对网络切片实例进行计费处理的方法、系统及相关设备Method, system and related equipment for charging network slice instance

技术领域technical field

本申请涉及通信领域，尤其涉及一种对网络切片实例进行计费处理的方法、系统以及相关设备。The present application relates to the field of communications, and in particular, to a method, system, and related equipment for performing charging processing on network slice instances.

背景技术Background technique

5G(5th Generation，第五代)网络的主要应用场景包括eMBB(enhanced MobileBroadband，增强移动宽带)、uRLLC(ultra High-Reliability and Low-LatencyCommunication，超高可靠性低时延通信)、mMTC(massive Machine Type Communication，大连接机器类通信)等。这些场景对网络特性的需求有很大的差异，例如：mMTC场景会有非常多的设备，但每个设备的吞吐量可能非常低，需要的带宽很小；而eMBB场景则需要几乎相反的特性，因为它将具有少得多的设备，但是每个设备都将发送或接收大量数据，需要的带宽很大；uRLLC场景则对端到端的时延要求很高，如自动驾驶，时延要求小于3毫秒。为满足上述不同应用场景的需求，可以在端到端的层面上对物理网络进行划分，以形成网络切片(Network Slice)，实现流量分组、隔离租户和宏观层面的资源配置。网络切片的本质是在共享的物理网络基础设施之上运行的虚拟网络，运营商可以根据不同的服务需求(比如时延、带宽、安全性和可靠性等)在物理网络基础上创建出满足相应服务需求的虚拟网络(对应为一个网络切片实例，Network Slice Instance，NSI)，以供有不同网络特性需求的客户使用，从而提高网络资源的利用率以及网络服务的服务质量。The main application scenarios of 5G (5th Generation) networks include eMBB (enhanced Mobile Broadband), uRLLC (ultra High-Reliability and Low-Latency Communication), mMTC (massive Machine) Type Communication, large connection machine type communication) and so on. These scenarios have very different requirements for network features. For example, the mMTC scenario will have a lot of devices, but the throughput of each device may be very low and the required bandwidth is very small; while the eMBB scenario requires almost the opposite features. , because it will have much fewer devices, but each device will send or receive a large amount of data, requiring a lot of bandwidth; uRLLC scenarios have high end-to-end latency requirements, such as autonomous driving, the latency requirement is less than 3 ms. In order to meet the requirements of the above different application scenarios, the physical network can be divided at the end-to-end level to form a network slice (Network Slice) to realize traffic grouping, tenant isolation and resource allocation at the macro level. The essence of network slicing is a virtual network running on a shared physical network infrastructure. Operators can create virtual networks on the basis of physical networks to meet different service requirements (such as delay, bandwidth, security, and reliability, etc.). The virtual network of service requirements (corresponding to a network slice instance, Network Slice Instance, NSI) is used by customers with different network characteristic requirements, thereby improving the utilization rate of network resources and the service quality of network services.

现有技术中，对网络资源进行计费处理的方案是，由业务系统根据业务的开始、结束等业务事件触发计费系统进行计费，同时业务系统统计准确的业务信息(如业务使用的流量、业务使用的时长等)，上报给计费系统，以使计费系统据此进行批价和扣费。In the prior art, the solution for charging network resources is that the business system triggers the billing system to perform billing according to business events such as the start and end of the business, and the business system counts accurate business information (such as the traffic used by the business). , the duration of business use, etc.), and report it to the billing system, so that the billing system can conduct pricing and deductions accordingly.

假如仍然按照上述计费处理方案对网络切片实例进行计费处理，则将导致计费结果与运营商为相应网络切片实例的投入不匹配，从而不利于实施上述多样化应用场景，进而降低网络资源的使用效率或降低网络服务的服务质量。If the network slicing instance is still charged according to the above charging processing scheme, the charging result will not match the operator's investment in the corresponding network slicing instance, which is not conducive to the implementation of the above-mentioned diversified application scenarios, thereby reducing network resources. use efficiency or reduce the service quality of network services.

为便于理解本申请中的实例，下面进一步解释几个与网络切片性能指标有关的概念：In order to facilitate the understanding of the examples in this application, several concepts related to network slicing performance indicators are further explained below:

(1)网络切片性能指标(Network Slice Performance Parameter,NSPP)：是用于描述所述网络切片实例的网络性能的参数或参数集，可以包括但不限于下述参数中的一个或多个：(1) Network Slice Performance Parameter (NSPP): is a parameter or parameter set used to describe the network performance of the network slice instance, which may include but is not limited to one or more of the following parameters:

-端到端时延：指数据包在网络切片实例的接入域、传输域和核心网域的传输时延；-End-to-end delay: refers to the transmission delay of data packets in the access domain, transmission domain and core network domain of a network slice instance;

-PDU(protocol data unit session，协议数据单元)会话数：指在网络切片实例上建立的PDU会话数量(即使用该网络切片实例的用户设备与该网络切片上数据网关之间建立的PDU会话的数量)；-Number of PDU (protocol data unit session, protocol data unit) sessions: refers to the number of PDU sessions established on the network slice instance (that is, the number of PDU sessions established between the user equipment using the network slice instance and the data gateway on the network slice) quantity);

-带宽：指网络切片实例所有并发PDU session所使用的带宽的总和；-Bandwidth: refers to the total bandwidth used by all concurrent PDU sessions of the network slice instance;

-用户数：指实际使用过或者并发使用该网络切片实例的用户数量或者注册在该网络切片实例上的用户的数量；- Number of users: refers to the number of users who have actually used or concurrently used the network slice instance or the number of users registered on the network slice instance;

为叙述方便，本申请实施例中也将网络切片性能指标简称为“指标”。For the convenience of description, the network slicing performance indicator is also referred to as an "indicator" for short in this embodiment of the present application.

应理解，一个网络切片实例可以具有一个或多个网络切片性能指标，本申请实施例对网络切片实例的网络切片性能指标的个数不作限定。It should be understood that a network slice instance may have one or more network slice performance indicators, and the embodiment of the present application does not limit the number of network slice performance indicators of the network slice instance.

相对于业务相关的指标(如流量)，网络切片性能指标既能体现客户或用户在使用所述网络切片实例上的关注点，又能体现运营商在所述网络切片实例上的投入，因此，基于网络切片性能指标对应的数据进行计费可以兼顾双方的利益。例如，运营商与客户可以就网络切片实例约定SLA(Service Level Agreement，服务等级协议)，可以约定网络切片性能指标的约束条件，例如，“时延超过5ms次数应在10次以内”，“带宽低于100G的累计时间不超过30小时”等，并约定在SLA的不同满足程度下的计费方法或计费费率。Compared with service-related indicators (such as traffic), network slicing performance indicators can not only reflect the concerns of customers or users in using the network slicing instance, but also reflect the operator's investment in the network slicing instance. Therefore, Billing based on data corresponding to network slice performance indicators can take into account the interests of both parties. For example, operators and customers can agree on SLAs (Service Level Agreements) for network slicing instances, and can agree on the constraints of network slicing performance indicators, for example, "the number of times the delay exceeds 5ms should be within 10 times", "the bandwidth The accumulated time less than 100G shall not exceed 30 hours”, etc., and the billing method or billing rate under different SLA satisfaction levels shall be agreed.

在具体实现中，通过消息传递的网络切片性能指标可以用指标的参数名称或参数标识来表示，例如，用“E2EDelay”或“101”表示“时延”这个网络切片性能指标。本申请实施例对网络切片性能指标的表示方式不作限定。为叙述方便，本申请实施例以参数名称为例进行说明。In a specific implementation, the network slice performance indicator passed through the message can be represented by the parameter name or parameter identifier of the indicator. For example, "E2EDelay" or "101" is used to represent the network slice performance indicator of "delay".

(4)网络切片性能指标的约束条件：是指对某个统计时间范围内网络切片性能指标的值的量化约束或量化要求，通常用数值范围来表示，也可以用具体数值来表示。例如，“带宽”这个指标的约束条件可以为“月平均带宽＝100M”，也可以为“带宽小于100M的累计时长不超过30小时”，“时延”这个指标的约束条件可以为“时延超过50ms的次数小于10次”等；网络切片性能指标的约束条件通常是在客户订购网络切片实例过程中与运营商达成一致的结果。(4) Constraints of network slicing performance indicators: refers to the quantitative constraints or quantitative requirements on the values of network slicing performance indicators within a certain statistical time range. For example, the constraint condition of the "bandwidth" indicator can be "monthly average bandwidth = 100M", or it can be "the cumulative duration of the bandwidth less than 100M does not exceed 30 hours", and the constraint condition of the "latency" indicator can be "delay" The number of times exceeding 50ms is less than 10 times”, etc.; the constraints of network slicing performance indicators are usually the result of agreement with operators during the process of ordering network slicing instances by customers.

(5)网络切片性能指标的统计值：是指按照一定的统计方法，对采样时间或获取时间落在某个统计时间范围内的网络切片性能指标的值进行统计得到的结果。所述统计方法，可以是与约束条件无关的统计方法，例如求平均值、加权平均值等，也可以是与约束条件相关的统计方法，即根据约束条件中的参数确定的统计方法。下面结合几种网络切片性能指标的统计值的类型分别举例说明，参见表1所示的情况。应理解，网络切片性能指标的统计值的类型并不限于表1所列情形。(5) Statistical values of network slice performance indicators: refers to the results obtained by performing statistics on the values of network slice performance indicators whose sampling time or acquisition time falls within a certain statistical time range according to a certain statistical method. The statistical method may be a statistical method unrelated to constraints, such as averaging, weighted average, etc., or a statistical method related to constraints, that is, a statistical method determined according to parameters in the constraints. The following is an example of the types of statistical values of several network slice performance indicators, referring to the situations shown in Table 1. It should be understood that the types of statistical values of network slice performance indicators are not limited to the situations listed in Table 1.

例如，当需要变更所述RPC中的结束条件，则所述变更指示可以是“变更结束条件”的指示，以指示NSMF设备提前或延迟结束上报的时间点；再如，当需要NSMF设备在收到变更指示后，立即上报性能指标对应的数据，则所述变更指示可以是“立即上报”的指示，以便NSMF设备将当前未上报的性能指标对应的数据上报给NSCF设备进行计费处理或者输出账单。For example, when the end condition in the RPC needs to be changed, the change instruction may be an indication of "change end condition" to indicate the time point at which the NSMF device ends the reporting earlier or later; for another example, when the NSMF device is required to receive After the change instruction, the data corresponding to the performance index is reported immediately, and the change instruction may be an "immediately report" instruction, so that the NSMF device reports the data corresponding to the performance index that is not currently reported to the NSCF device for charging processing or output. bill.

可选地，所述PPROId可以使用上述NSIId代替，NSMF设备可以使用NSIId作为PPRO标识，也可以在本地建立NSIId与PPROId的映射关系，再通过该映射关系由NSIId确定相应的PPROId，从而可以根据PPROId确定相应的PPRO的计算资源，进而对其进行变更。Optionally, the PPROId can be replaced by the above-mentioned NSIId, the NSMF device can use the NSIId as the PPRO identifier, or can establish a mapping relationship between the NSIId and the PPROId locally, and then determine the corresponding PPROId by the NSIId through the mapping relationship, so that the PPROId can be determined according to the PPROId. Determine the computing resources of the corresponding PPRO, and then change it.

步骤208：NSMF设备基于变更指示，改变PPRO的操作过程。Step 208: The NSMF device changes the operation process of the PPRO based on the change instruction.

具体地，NSMF设备接收步骤207所述的请求消息并从中解析出所述PPRO标识PPROId和所述变更指示，基于所述PPRO标识和所述变更指示，对所述PPRO执行与所述变更指示相应的变更操作，例如：对于“变更结束条件”的指示，执行改变结束条件的操作；对于“立即上报”的指示，执行立即上报所述上报指标对应的数据的操作；对于“变更上报周期”的指示，执行调整上报周期的操作。Specifically, the NSMF device receives the request message in step 207 and parses out the PPRO identifier PPROId and the change instruction, and executes the PPRO corresponding to the change instruction based on the PPRO identifier and the change instruction. For example, for the instruction of "change end condition", execute the operation of changing the end condition; for the instruction of "immediately report", execute the operation of immediately reporting the data corresponding to the reporting indicator; for the instruction of "change the reporting period" Indicate, perform the operation of adjusting the reporting period.

需要说明的是，步骤206-步骤208可以在步骤204-步骤205之前、期间或者之后进行，即对PPRO的变更，可以发生在PPRO开始前、执行过程中或者执行之后，图2所示顺序仅是示例性的，并非限定这些步骤的执行顺序。步骤206-208为可选步骤，即中途对PPRO进行变更是可选的。It should be noted that steps 206 to 208 can be performed before, during or after steps 204 to 205, that is, changes to the PPRO can occur before, during or after the execution of the PPRO. The sequence shown in FIG. 2 is only It is exemplary and does not limit the order in which the steps are performed. Steps 206-208 are optional steps, that is, it is optional to change the PPRO in the middle.

步骤209：NSCCF设备确定需要结束PPRO。Step 209: The NSCCF device determines that the PPRO needs to be terminated.

具体地，NSCCF设备根据关于所述NSI的订购信息的变更或者其他计费因素的变化，确定需要结束所述PPRO。Specifically, the NSCCF device determines that the PPRO needs to be terminated according to changes in subscription information about the NSI or changes in other charging factors.

例如，当客户在订购周期结束之前提出结束订购，或者在订购周期结束之前，客户账上的余额已经不足，则可以确定出需要结束所述PPRO的执行。For example, when the customer proposes to terminate the order before the end of the order period, or the balance in the customer's account is insufficient before the end of the order period, it may be determined that the execution of the PPRO needs to be terminated.

步骤210：NSCCF设备向NSMF设备发送PPRO标识PPROId和结束指示。Step 210: The NSCCF device sends the PPRO identifier PPROId and an end indication to the NSMF device.

具体地，NSCCF设备向NSMF设备发送请求消息(本申请实施例不限定该请求消息的名称，例如，可以为“结束PPRO请求”或者“删除PPRO请求”)，所述请求消息包含所述PPRO标识PPROId和结束指示，所述结束指示用于指示NSMF设备结束所述PPRO。Specifically, the NSCCF device sends a request message to the NSMF device (the name of the request message is not limited in the embodiment of this application, for example, it can be "end PPRO request" or "delete PPRO request"), the request message contains the PPRO identifier PPROId and an end indication, where the end indication is used to instruct the NSMF device to end the PPRO.

步骤211：NSMF设备确定需要结束PPRO。Step 211: The NSMF device determines that the PPRO needs to be terminated.

如果NSMF设备通过步骤210从NSCCF设备接收到结束指示，则可以不执行本步骤，否则，具体地，NSMF设备根据上述RPC中的结束条件，确定出需要结束所述PPRO的执行。也就是说，NSMF设备至少存在两种触发因素结束所述PPRO，一种是收到NSCCF设备发送的结束指示，另一种是自身判断所述RPC中的结束条件满足(如到达结束时间点)。If the NSMF device receives an end indication from the NSCCF device through step 210, this step may not be performed, otherwise, specifically, the NSMF device determines that the execution of the PPRO needs to be ended according to the end condition in the above RPC. That is to say, there are at least two trigger factors for the NSMF device to end the PPRO, one is to receive the end instruction sent by the NSCCF device, and the other is to judge that the end condition in the RPC is satisfied (such as reaching the end time point) .

步骤212：NSMF设备向NSCF设备发送结束上报指示和RPC中上报指标对应的数据。Step 212: The NSMF device sends the NSCF device the end reporting indication and the data corresponding to the reporting indicator in the RPC.

具体地，NSMF设备通过步骤210或者步骤211，确定需要结束PPRO的执行，可以向NSCF设备发送请求消息(本申请实施例不限定该请求消息的名称，例如，可以为“网络切片计费结束请求”或者“网络切片性能指标上报结束请求”)，所述请求消息中包含结束上报指示，以使NSCF设备进行相应的计费处理，如输出账单等。可选地，所述请求消息还可以包含所述RPC中上报指标对应的数据，以将尚未上报的所述上报指标对应的数据上报给NSCF设备。Specifically, the NSMF device determines through step 210 or step 211 that the execution of the PPRO needs to be terminated, and can send a request message to the NSCF device (this embodiment of the present application does not limit the name of the request message, for example, it can be "Network slice charging end request" "or "Network Slicing Performance Indicator Reporting End Request"), the request message includes an end reporting indication, so that the NSCF device performs corresponding charging processing, such as outputting bills, etc. Optionally, the request message may further include data corresponding to the reporting indicator in the RPC, so as to report the data corresponding to the reporting indicator that has not been reported to the NSCF device.

需要说明的是，步骤209-步骤212可以在步骤204-步骤205执行期间或执行之后进行。图2所示顺序仅是示例性的，并非限定这些步骤的执行顺序。步骤209-步骤210为NSMF设备被动确定需要结束PPRO(NSCCF设备触发结束)，步骤211为NSMF设备自主确定需要结束PPRO，可以二者选其一。It should be noted that, steps 209 to 212 may be performed during or after the execution of steps 204 to 205 . The sequence shown in FIG. 2 is only exemplary and does not limit the execution sequence of these steps. Steps 209 to 210 are that the NSMF device passively determines that the PPRO needs to be terminated (NSCCF device triggers the termination), and step 211 is that the NSMF device autonomously determines that the PPRO needs to be terminated, and one of the two can be selected.

为描述方便，上述方法流程中以一个NSI对应一个RPC为例进行说明，但本申请实施例并不限定上述方法流程中的NSI个数和相应RPC的个数，例如，当一个客户订购了多个网络切片实例时，可以在步骤202的请求消息中包含多个NSIId和多个相应的RPC，或者包含多个NSIId和共用的RPC(也就是NSIId和RPC可以一一对应，也可以多对一，还可以多对多)，步骤204中可以针对不同的NSI分别上报各自上报指标对应的数据，步骤207或步骤210中的请求消息中可以用NSIId或其他标识NSI对应的上报操作的信息替代PPROId，以分别管理或结束每个NSI对应的上报指标对应的数据的获取和上报操作，如仍用PPROId，则可以表示对所述多个NSI执行相应的管理操作，例如步骤210的请求消息中包含PPROId和结束指示，则表示停止所述多个NSI对应的上报指标对应的数据的获取和上报操作，而如果该请求消息中包含一个NSIId和结束指示，则表示停止该NSIId对应的NSI的上报指标对应的数据的获取和上报操作，其他NSI的上报指标对应的数据的获取和上报操作不受影响。For the convenience of description, the above method flow is described by taking one NSI corresponding to one RPC as an example, but the embodiments of the present application do not limit the number of NSIs and the number of corresponding RPCs in the above method flow. In the case of a network slice instance, the request message in step 202 may contain multiple NSIIds and multiple corresponding RPCs, or multiple NSIIds and shared RPCs (that is, NSIIds and RPCs may correspond one-to-one or many-to-one). , can also be many-to-many), in step 204, the data corresponding to the respective reporting indicators can be reported for different NSIs respectively, and in the request message in step 207 or step 210, NSIId or other information that identifies the reporting operation corresponding to the NSI can be used to replace PPROId , to separately manage or end the acquisition and reporting operations of the data corresponding to the reporting indicators corresponding to each NSI. If PPROId is still used, it can indicate that corresponding management operations are performed on the multiple NSIs. For example, the request message in step 210 contains PPROId and end indication, it means to stop the acquisition and reporting operation of the data corresponding to the reporting indicators corresponding to the multiple NSIs, and if the request message contains an NSIId and an end indication, it means to stop the reporting indicators of the NSI corresponding to the NSId The corresponding data acquisition and reporting operations, and the data acquisition and reporting operations corresponding to other NSI reporting indicators are not affected.

相对于传统上基于终端业务数据(如流量或时长)的线性方式的计费方法而言，图2对应的对网络切片实例进行计费处理的方法，可以基于网络切片性能指标对应的数据对网络切片实例进行计费处理，由于网络切片性能指标对应的数据既是客户所关心的数据，又能更好地体现运营商的投入，因此有助于提高计费结果与网络资源投入的匹配程度，有利于实施上述多样化应用场景，进而有助于提高网络资源的使用效率或提高网络服务的服务质量。Compared with the traditional linear charging method based on terminal service data (such as traffic or duration), the method for charging a network slice instance corresponding to FIG. The slicing instance performs billing processing. Since the data corresponding to the network slicing performance indicators is not only the data that customers care about, but also better reflects the operator's investment, so it helps to improve the matching degree between the billing result and the network resource investment. It is beneficial to implement the above-mentioned diversified application scenarios, thereby helping to improve the use efficiency of network resources or improve the service quality of network services.

图3A为本申请实施例提供的对网络资源进行计费处理的又一方法流程图，该方法流程基于图1所示的架构实现，其中NSCCF设备对应图1中的NSCCF设备101，NSMF设备对应图1中的NSMF设备103，NSCF设备对应图1中的NSCF设备102。该方法流程以较具体的例子说明NSCCF设备如何确定PPRO的RPC、NSMF设备如何据此执行PPRO以实现对网络切片实例进行计费处理，具体包括如下步骤：3A is a flowchart of another method for performing charging processing on network resources provided by an embodiment of the present application. The method flowchart is implemented based on the architecture shown in FIG. 1 , wherein the NSCCF device corresponds to theNSCCF device 101 in FIG. 1 , and the NSMF device corresponds to TheNSMF device 103 and the NSCF device in FIG. 1 correspond to theNSCF device 102 in FIG. 1 . The method flow uses a specific example to illustrate how the NSCCF device determines the RPC of the PPRO and how the NSMF device executes the PPRO accordingly to implement the charging processing for the network slice instance, which specifically includes the following steps:

步骤301：NSCCF设备确定针对NSI的性能指标上报操作PPRO的上报参数集RPC01。Step 301: The NSCCF device determines the reporting parameter set RPC01 of the NSI performance indicator reporting operation PPRO.

具体地，对于给定的NSI(其标识为NSIId01)，NSCCF设备可以根据所述NSI的订购信息、所述NSI的信息、运营商预先配置的信息和客户账户余额信息中的任意一项或任意组合，确定针对所述NSI的性能指标上报操作PPRO的上报参数集合RPC如下：Specifically, for a given NSI (identified as NSIId01), the NSCCF device can use any one or any of the subscription information of the NSI, the information of the NSI, the information pre-configured by the operator, and the customer account balance information. Combining, determine the reporting parameter set RPC of the performance indicator reporting operation PPRO for the NSI as follows:

应理解，RPC01中的各项上报参数是可选的，当其在上述RPC数据结构中不出现或者取值为空值时，可以视为NSCCF设备和NSMF设备之间达成一致的默认值，例如“上报地址”可以采用NSMF设备和NSCCF设备共同默认的NSCF设备的地址和端口。It should be understood that each reporting parameter in RPC01 is optional, and when it does not appear in the above RPC data structure or takes a null value, it can be regarded as a default value agreed between the NSCCF device and the NSMF device, for example The "reporting address" can use the default address and port of the NSCF device that are shared by the NSMF device and the NSCCF device.

应理解，本申请实施例并不限定上报参数集的表示形式，例如，也可以采用脚本或者伪代码的形式表示，将RPC01表示如下：It should be understood that the embodiment of the present application does not limit the representation form of the reporting parameter set. For example, it can also be represented in the form of a script or pseudocode, and RPC01 is represented as follows:

RPC的其他表示形式，本申请实施例不一一赘述。Other representations of the RPC are not described in detail in the embodiments of the present application.

步骤302：NSCCF设备向NSMF设备发送创建PPRO请求，所述请求中包含NSIId01和RPC01。Step 302: The NSCCF device sends a request to create a PPRO to the NSMF device, where the request includes NSIId01 and RPC01.

步骤303：NSMF设备向NSCCF设备返回创建PPRO响应，所述响应中包含PPROId01。Step 303: The NSMF device returns a Create PPRO response to the NSCCF device, where the response includes PPROId01.

该步骤为可选，NSMF设备可以在步骤309再对上述创建PPRO请求作出响应。This step is optional, and the NSMF device may respond to the above request for creating a PPRO in step 309 .

具体地，NSMF设备接收NSIId01和RPC01后，确定需要执行的PPRO，并为其分配唯一标识PPROId01，并向NSCCF设备返回创建PPRO响应，所述响应中包含PPROId01。Specifically, after receiving NSIId01 and RPC01, the NSMF device determines the PPRO to be executed, assigns a unique identifier PPROId01 to it, and returns a PPRO creation response to the NSCCF device, where the response includes PPROId01.

应理解，PPROId01可以由NSMF设备分配并通过本步骤中创建PPRO响应返回给NSCCF设备，也可以由NSCCF设备分配或通过其他方式获取，并通过步骤302的创建PPRO请求中发送给NSMF设备，即步骤302的创建PPRO请求中，除了包含NSIId01和RPC01外，还可以包含NSCCF设备分配的PPROId01。所述创建PPRO相应中包含的PPROId01，可以用于后续对相应的PPRO进行管理(变更、结束等)，也可以用于向NSCCF设备表示所述创建PPRO请求得到成功处理。It should be understood that PPROId01 can be allocated by the NSMF device and returned to the NSCCF device by creating a PPRO response in this step, or it can be allocated by the NSCCF device or acquired by other means, and sent to the NSMF device through the creating PPRO request in step 302, that is, step 302. In addition to NSIId01 and RPC01, the create PPRO request of 302 may also include PPROId01 allocated by the NSCCF device. The PPROId01 included in the PPRO creation response can be used for subsequent management (change, termination, etc.) of the corresponding PPRO, and can also be used to indicate to the NSCCF device that the PPRO creation request has been successfully processed.

步骤304：NSMF设备确定开始条件满足。Step 304: The NSMF device determines that the start condition is satisfied.

具体地，NSMF设备确定当前时间为“20190101:00:00:00”，满足RPC01中的开始条件。Specifically, the NSMF device determines that the current time is "20190101:00:00:00", which satisfies the start condition in RPC01.

RPC01中，开始条件不限于“到达某个时间点”，也可以是其他条件，例如，“网络切片实例开始得到使用”或者“有用户设备接入网络切片实例”，则NSMF设备可以监视网络切片实例的运行状态，一旦有用户设备接入网络切片实例，即确定开始条件满足。NSMF设备确定满足开始条件将因RPC中的开始条件不同而有所不同，本申请实施例不一一赘述。In RPC01, the start condition is not limited to "a certain time point", but can also be other conditions, for example, "the network slice instance is started to be used" or "there is a user equipment connected to the network slice instance", then the NSMF device can monitor the network slice The running state of the instance, once a user equipment accesses the network slice instance, it is determined that the start condition is satisfied. The determination by the NSMF device that the start condition is satisfied will vary due to different start conditions in the RPC, which are not described in detail in the embodiments of the present application.

步骤305：NSMF设备开始获取上报指标对应的数据。Step 305: The NSMF device starts to acquire the data corresponding to the reported indicator.

具体地，NSMF设备根据RPC01中的上报指标(即“带宽”)，开始获取NSIId01对应的网络切片实例的带宽数据。Specifically, the NSMF device starts to acquire the bandwidth data of the network slice instance corresponding to NSIId01 according to the reported indicator (ie, "bandwidth") in RPC01.

步骤306：NSMF设备向NSCF设备发送网络切片NS计费初始请求，所述NS计费初始请求中包含NSIId01。Step 306: The NSMF device sends an initial NS charging request for the network slice to the NSCF device, where the initial NS charging request includes NSIId01.

具体地，NSMF设备根据RPC01中的上报方式为“会话上报”，确定需要在其与NSCF设备之间建立计费会话，以便后续基于该计费会话上报RPC01中的上报指标对应的数据，进而根据RPC01中的上报地址“http://NSCF-ip:port”向NSCF设备发起NS计费初始请求，所述NS初始请求中包含NSIId01，以与NSCF设备建立计费会话。可选地，所述NS计费初始请求还可以包含“创建会话”的指示信息，用于指示NSCF设备创建计费会话，并分配所述计费会话的唯一标识。Specifically, the NSMF device determines that a charging session needs to be established between it and the NSCF device according to the reporting method in RPC01 as "session reporting", so as to subsequently report the data corresponding to the reporting indicators in RPC01 based on the charging session, and then according to The reporting address "http://NSCF-ip:port" in RPC01 initiates an initial NS charging request to the NSCF device, where the initial NS request includes NSIId01 to establish a charging session with the NSCF device. Optionally, the NS charging initial request may further include "create session" indication information, which is used to instruct the NSCF device to create a charging session and assign a unique identifier of the charging session.

应理解，“NS计费初始请求”是示例性消息名称，该消息可以是其他名称，例如“创建计费会话请求”等。It should be understood that "NS Charging Initial Request" is an exemplary message name, and the message may be other names such as "Create Charging Session Request" and the like.

步骤307：NSCF设备创建计费会话CS01。Step 307: The NSCF device creates a charging session CS01.

具体地，NSCF设备接收到所述NS计费初始请求并从中解析出NSIId01，并创建计费会话(Charging Session，CS)，例如CS01，并为CS01分配唯一标识CSId01。可选地，NSCF设备还可以从所述NS计费初始请求中解析出“创建会话”的指示信息，并根据该指示信息创建CS01。在所述NS计费初始请求不包含“创建会话”的指示信息的情况下，NSCF设备可以将所述NS计费初始请求消息名称作为创建CS01的依据，也就是说，NSCF设备在接收到该消息时，默认建立计费会话、分配计费会话标识且在响应消息中返回计费会话标识。NSCF设备也可以根据NSIId01从NSMF设备或其他设备获取相应NSI的信息，并根据NSI的信息，如NSI的类型(如eMBB类型),确定需要创建所述计费会话CS01。对此，本申请实施例不做限定。Specifically, the NSCF device receives the initial NS charging request and parses the NSIId01 from it, creates a charging session (Charging Session, CS), such as CS01, and assigns CS01 a unique identifier CSId01. Optionally, the NSCF device may also parse out the indication information of "create a session" from the initial NS charging request, and create CS01 according to the indication information. In the case that the NS charging initial request does not contain the indication information of "create session", the NSCF device can use the NS charging initial request message name as the basis for creating CS01, that is, the NSCF device receives the message, the charging session is established by default, the charging session identifier is allocated, and the charging session identifier is returned in the response message. The NSCF device can also obtain the corresponding NSI information from the NSMF device or other devices according to NSIId01, and determine that the charging session CS01 needs to be created according to the NSI information, such as the NSI type (eg eMBB type). In this regard, the embodiment of the present application does not limit it.

步骤308：NSCF设备向NSMF设备返回NS计费初始响应，所述NS计费初始响应中包含CSId01。Step 308: The NSCF device returns an NS charging initial response to the NSMF device, where the NS charging initial response includes CSId01.

CSId01可以用于NSMF设备后续向NSCF设备上报所述上报指标对应的数据，也可以用于在NSMF设备中区分不同NSI对应的上报过程或上报操作，适用于一个客户有多个NSI，或者一个PPRO中要上报多个NSI的上报指标对应的数据的情况。此外，CSId01也可以用于表示所述NS计费初始请求得到成功处理。CSId01 can be used by the NSMF device to subsequently report the data corresponding to the reporting indicator to the NSCF device, and can also be used to distinguish the reporting process or reporting operation corresponding to different NSIs in the NSMF device. It is suitable for a customer with multiple NSIs, or a PPRO In the case where the data corresponding to the reporting indicators of multiple NSIs needs to be reported. In addition, CSId01 can also be used to indicate that the NS charging initial request has been successfully processed.

应理解，CSId01可以由NSCF设备在步骤307中分配再通过步骤308的NS计费初始响应返回给NSMF设备，也可以由NSMF设备在步骤306之前分配再通过步骤306的NS计费初始请求发送给NSCF设备，对此，本申请实施例不作限定。It should be understood that the CSId01 can be allocated by the NSCF device in step 307 and then returned to the NSMF device through the NS charging initial response in step 308, or can be allocated by the NSMF device before step 306 and then sent to the NSMF device through the NS charging initial request in step 306. NSCF equipment, which is not limited in this embodiment of the present application.

应理解，步骤305也可以改为在步骤308之后执行，即：NSMF设备可以在与NSCF设备建立计费会话之前开始获取上报指标对应的数据，也可以在建立计费会话之后再开始获取所述上报指标对应的数据。图3A所示步骤的顺序只是一种示例，并非时序上的限定。It should be understood that step 305 can also be changed to be executed after step 308, that is, the NSMF device can start to acquire the data corresponding to the reported indicators before establishing a charging session with the NSCF device, or it can start to acquire the data after the charging session is established. Report the data corresponding to the indicator. The sequence of the steps shown in FIG. 3A is only an example, and is not limited in timing.

步骤309：NSMF设备向NSCCF设备返回创建PPRO响应，所述创建PPRO响应中包含PPRO标识PPROId01和所述计费会话标识CSId01。Step 309: The NSMF device returns a PPRO creation response to the NSCCF device, where the PPRO creation response includes the PPRO identifier PPROId01 and the charging session identifier CSId01.

如果NSMF设备在步骤303对创建PPRO请求作出响应，则本步骤可以省略。If the NSMF device responds to the create PPRO request in step 303, this step may be omitted.

NSMF设备可以将所述PPROId01和所述CSId01通过两个参数分别包含在所述创建PPRO响应中，也可以通过一个参数包含在所述创建PPRO响应中。例如，可以用“PPROId01_CSId01”表示既包含PPROId01也包含CSId01的参数或信息，这里“包含”的含义是，从所述参数或信息中可以解析出或者读取出所述PPROId01和所述CSId01。例如，假设一个参数是一个字符串，包含64个字符，则前32个字符对应PPROId01，用于唯一标识PPRO自身，后32个字符对应CSId01，用于唯一标识与所述NSI对应的计费会话CS01，NSMF设备可以将该长度为64的字符串包含在所述创建PPRO响应中，NSCCF设备可以从该字符串中解析或读取前32个字符作为PPROId01，后32个字符作为CSId01。The NSMF device may respectively include the PPROId01 and the CSId01 in the Create PPRO response through two parameters, or may include the PPROId01 in the Create PPRO response through one parameter. For example, "PPROId01_CSId01" may be used to indicate parameters or information including both PPROId01 and CSId01, where "includes" means that the PPROId01 and the CSId01 can be parsed or read from the parameters or information. For example, assuming that a parameter is a string containing 64 characters, the first 32 characters correspond to PPROId01, which is used to uniquely identify the PPRO itself, and the last 32 characters correspond to CSId01, which is used to uniquely identify the charging session corresponding to the NSI. CS01, the NSMF device can include the string of length 64 in the Create PPRO response, and the NSCCF device can parse or read the first 32 characters from the string as PPROId01, and the last 32 characters as CSId01.

与步骤303类似，PPROId01用于后续对相应的PPRO进行管理(变更、结束等)，也可以用于表示所述创建PPRO请求得到成功处理。由于所述创建PPRO响应中还包含了CSId01，后续NSCCF设备可以基于PPROId01也可以基于CSId01向NSMF设备发起管理(变更、结束等)指令或管理消息。Similar to step 303, PPROId01 is used for subsequent management (change, termination, etc.) of the corresponding PPRO, and may also be used to indicate that the request for creating a PPRO has been successfully processed. Since the Create PPRO response also includes CSId01, the subsequent NSCCF device may send a management (change, end, etc.) instruction or management message to the NSMF device based on PPROId01 or CSId01.

应理解，在所述PPRO中仅向NSCF设备上报一个NSI(即NSIId01对应的NSI)的性能指标对应的数据的情况下，所述创建PPRO响应中也可以不包含CSId01，NSCCF设备后续可以基于PPROId01向NSMF设备发送管理指令，NSMF设备可以事先在本地维护PPROId到CSId的对应关系，根据该对应关系由PPROId01找到相应的CSId01，并基于CSId01向NSCF设备发起各种计费消息。It should be understood that in the case that only the data corresponding to the performance index of one NSI (that is, the NSI corresponding to NSIId01) is reported to the NSCF device in the PPRO, the CSId01 may not be included in the PPRO response created, and the NSCCF device can subsequently be based on the PPROId01 Send a management instruction to the NSMF device. The NSMF device can maintain the corresponding relationship between PPROId and CSId locally in advance. According to the corresponding relationship, PPROId01 finds the corresponding CSId01, and sends various charging messages to the NSCF device based on CSId01.

应理解，当所述PPRO中向NSCF设备上报多个NSI的性能指标对应的数据的情况下，所述创建PPRO响应中可以包含PPROId01与多组NSIId与CSId的对应关系(在此之前，NSMF设备可以针对每一个NSI向NSCF设备分别发起NS计费初始请求，以使NSCF设备为每一个NSI分别创建计费会话)，例如一个创建PPRO响应可以为：It should be understood that when the data corresponding to the performance indicators of multiple NSIs is reported to the NSCF device in the PPRO, the corresponding relationship between PPROId01 and multiple groups of NSIId and CSId may be included in the created PPRO response (before this, the NSMF device An initial request for NS charging can be initiated to the NSCF device for each NSI, so that the NSCF device can create a charging session for each NSI. For example, a Create PPRO response can be:

从而，当NSCCF设备需要针对某一个NSI的上报操作进行管理的情况下，可以基于对应的CSId向NSMF设备发起管理指令或管理消息。Therefore, when the NSCCF device needs to manage the reporting operation of a certain NSI, it can send a management instruction or a management message to the NSMF device based on the corresponding CSId.

应理解，当所述PPRO中向NSCF设备上报多个NSI的性能指标对应的数据的情况下，所述创建PPRO响应中也可以不包含每个NSI对应的计费会话标识CSId。NSCCF设备后续可以基于网络切片实例的标识NSIId向NSMF设备发送管理指令，NSMF设备可以事先在本地维护NSIId到CSId的对应关系，根据该对应关系由NSIId找到相应的CSId，并基于CSId向NSCF设备发起各种计费消息。It should be understood that when the data corresponding to the performance indicators of multiple NSIs is reported to the NSCF device in the PPRO, the PPRO creation response may not include the charging session identifier CSId corresponding to each NSI. The NSCCF device can subsequently send management instructions to the NSMF device based on the identifier NSIId of the network slicing instance. The NSMF device can maintain the corresponding relationship between the NSIId and the CSId locally in advance. According to the corresponding relationship, the NSIId can find the corresponding CSId, and based on the CSId, send a message to the NSCF device. Various billing messages.

关于PPROId及CSId的使用，可进一步参考步骤319、步骤322和步骤327及其相关步骤中的说明。Regarding the use of PPROId and CSId, further reference may be made to the descriptions in step 319 , step 322 , and step 327 and related steps.

步骤310：NSMF设备确定上报条件满足。Step 310: The NSMF device determines that the reporting condition is satisfied.

NSMF设备根据上报条件满足确定需要将所述RPC中上报指标对应的数据上报到NSCF设备是其确定需要将所述RPC中的上报指标对应的数据上报给所述NSCF设备的实现方式之一(另一种方式是根据从NSCCF设备接收到的上报指示确定，具体参见步骤322和步骤323等)。The NSMF device determines that it needs to report the data corresponding to the reporting index in the RPC to the NSCF device according to the reporting conditions. It is one of the implementations (otherwise) in which it determines that the data corresponding to the reporting index in the RPC needs to be reported to the NSCF device. One way is to determine according to the reporting indication received from the NSCCF device, see step 322 and step 323 for details).

由于RPC01中的上报条件为“每隔5分钟上报一次”，NSMF设备可以确定时间每推进5分钟均满足上报条件。为此，NSMF设备可以为上报启动周期为5分钟的循环定时器，定时时间结束时即满足上报条件。Since the reporting condition in RPC01 is "report every 5 minutes", the NSMF device can determine that the reporting condition is satisfied every 5 minutes of time advance. To this end, the NSMF device may start a cyclic timer with a period of 5 minutes for reporting, and the reporting conditions are met when the timing expires.

RPC01中，上报条件不限于“周期性上报”，也可以是其他条件，例如，“时延超过100ms”(假设RPC01中的上报指标为“时延”)，则NSMF设备需要监视所述NSI的端到端时延，在端到端时延超过100ms的情况下，确定上报条件满足。NSMF设备确定上报条件满足的方法将因RPC01中的上报条件的不同而有所不同，本申请实施例不一一赘述。In RPC01, the reporting condition is not limited to "periodic reporting", but can also be other conditions, for example, "delay exceeds 100ms" (assuming that the reporting indicator in RPC01 is "delay"), then the NSMF device needs to monitor the NSI's End-to-end delay, when the end-to-end delay exceeds 100ms, it is determined that the reporting conditions are met. The method for the NSMF device to determine that the reporting condition is satisfied will vary depending on the reporting condition in the RPC01, which will not be described in detail in this embodiment of the present application.

步骤311：NSMF设备向NSCF设备发送NS计费更新请求，所述NS计费更新请求中包含CSId01、上报指标对应的数据pfmParData01和上报原因rptRsn01。Step 311: The NSMF device sends an NS accounting update request to the NSCF device, where the NS accounting update request includes CSId01, data pfmParData01 corresponding to the reporting indicator, and reporting reason rptRsn01.

具体地，NSMF设备根据RPC01中的获取方式(即“获取采样值”)，获取上报指标“带宽”的采样值pfmParData01，并向NSCF设备发送NS计费更新请求，所述NS计费更新请求中包含CSId01，pfmParData01和上报原因rptRsn01，rptRsn01取值为“上报条件满足”，表明是NSMF设备在判断上报条件满足的情况下向NSCF设备上报带宽的采样值。Specifically, the NSMF device obtains the sampling value pfmParData01 of the reporting indicator "bandwidth" according to the acquisition method in RPC01 (ie, "obtain sampling value"), and sends an NS accounting update request to the NSCF device, where the NS accounting update request contains It includes CSId01, pfmParData01, and reporting reason rptRsn01. The value of rptRsn01 is "reporting condition is satisfied", indicating that the NSMF device reports the bandwidth sampling value to the NSCF device when it judges that the reporting condition is satisfied.

应理解，如果步骤308中所述NS计费初始响应中不包含CSId01，则本步骤所述NS计费更新请求中可以用NSIId01替代CSId01，NSCF设备可以用NSIId01作为计费会话CS01的标识。后续步骤中，CSId01均可以用NSIId01替代，将不再赘述。It should be understood that if CSId01 is not included in the NS charging initial response in step 308, NSIId01 can be used instead of CSId01 in the NS charging update request in this step, and the NSCF device can use NSIId01 as the identifier of the charging session CS01. In the subsequent steps, CSId01 can be replaced by NSIId01, which will not be repeated.

可选地，NSMF设备可以先存储所述上报指标对应的数据，将pfmParData01取值为所述上报指标对应的数据的存储地址，或者在pfmParData01中包含所述上报指标对应的数据的存储地址，再根据本步骤上述过程将其发送给NSCF设备。Optionally, the NSMF device may first store the data corresponding to the reporting indicator, set pfmParData01 as the storage address of the data corresponding to the reporting indicator, or include the storage address of the data corresponding to the reporting indicator in pfmParData01, and then Send it to the NSCF device according to the above procedure of this step.

步骤312：NSCF设备进行计费处理。Step 312: The NSCF device performs charging processing.

具体地，NSCF设备接收所述NS计费更新请求，并从中解析出CSId01、pfmParData01和rptRsn01，再基于CSId01、pfmParData01和rptRsn01进行计费处理，具体可以是：基于pfmParData01生成所述网络切片实例的计费话单，或者，基于pfmParData01以及所述NSI对应的计费规则，计算所述网络切片实例的使用费用。本步骤中，pfmParData01是上报指标对应的采样值(带宽的采样值)，但如果上述获取方式取其他值，pfmParData01也可以为上报指标对应的统计值，或者是上报指标的采样值或采样值与采样时间的组合。Specifically, the NSCF device receives the NS charging update request, parses out CSId01, pfmParData01, and rptRsn01 from it, and then performs charging processing based on CSId01, pfmParData01, and rptRsn01, which may specifically be: generating a calculation of the network slice instance based on pfmParData01 bill of charges, or, based on pfmParData01 and the charging rule corresponding to the NSI, calculate the usage fee of the network slice instance. In this step, pfmParData01 is the sampling value (sampling value of bandwidth) corresponding to the reported indicator, but if the above acquisition method takes other values, pfmParData01 can also be the statistical value corresponding to the reported indicator, or the sampled value of the reported indicator or the sampled value and the A combination of sample times.

当pfmParData01为上报指标的采样值与采样时间的组合时，NSCF设备可以将每一组该采样值与采样时间的组合写入NSIId01对应的指标采样值计费话单，后续基于所述指标采样值话单进行费用计算；NSCF设备也可以进一步确定出相应的统计时间范围和统计方法，并按照该统计方法对从所述指标采样值计费话单中的多组采样值与采样时间的组合进行统计，得到上报指标的统计值，进而使用该统计值计算NSIId01对应的网络切片实例的使用费用。When pfmParData01 is the combination of the sampling value and sampling time of the reported index, the NSCF device can write each combination of the sampling value and sampling time into the CDR for the index sampling value corresponding to NSIId01, and the subsequent charging based on the index sampling value The NSCF device can also further determine the corresponding statistical time range and statistical method, and according to the statistical method, calculate the combination of multiple groups of sampling values and sampling time in the charging CDR from the sampling value of the indicator. Statistics to obtain the statistical value of the reported indicator, and then use the statistical value to calculate the usage fee of the network slice instance corresponding to NSIId01.

当所述pfmParData01为上报指标的统计值时，NSCF设备可以将该统计值写入NSIId01对应的指标统计值话单，后续基于所述指标统计值话单进行费用计算；NSCF设备也可以使用该统计值直接计算NSIId01对应的网络切片实例的使用费用。When the pfmParData01 is the statistical value of the reported indicator, the NSCF device can write the statistical value into the CDR of the indicator statistical value corresponding to NSIId01, and subsequently perform cost calculation based on the CDR of the indicator statistical value; the NSCF device can also use the statistics The value directly calculates the usage fee of the network slice instance corresponding to NSIId01.

表-2为上述计费处理过程及相应的示例性适用场景。Table-2 shows the above charging processing procedures and corresponding exemplary applicable scenarios.

表-2Table 2

可选地，NSCF设备可以先获取相关计费规则，再基于所述计费规则和所述统计值计算所述网络切片实例的使用费用。例如，假设运营商为该网络切片模板配置的计费规则为“累计端到端时延超过50ms达10次以上月租减半”，上述上报指标为“时延”，其统计值为“11次”，则对上述网络切片实例的使用按50％的费率进行收费。可选地，NSCF设备可以从客户订购信息中获取所述计费规则。Optionally, the NSCF device may obtain relevant charging rules first, and then calculate the usage fee of the network slice instance based on the charging rules and the statistical value. For example, assuming that the charging rule configured by the operator for the network slice template is "The cumulative end-to-end delay exceeds 50ms and the monthly rent is halved for more than 10 times", the above reported indicator is "Latency", and its statistic value is "11" times”, the usage of the above network slice instance will be charged at a rate of 50%. Optionally, the NSCF device may acquire the charging rules from customer subscription information.

由于上报原因rptRsn01为“上报条件满足”，可暂不触发账单系统输出相应的计费账单。Because the reporting reason rptRsn01 is "reporting condition satisfied", the billing system can be temporarily not triggered to output the corresponding billing bill.

应理解，根据上报的pfmParData01和rptRsn01的不同，计费处理方式有所不同，本申请实施例不一一赘述。It should be understood that, according to the difference between the reported pfmParData01 and rptRsn01, the charging processing methods are different, and the embodiments of the present application will not describe them one by one.

可选地，当pfmParData01中包含所述上报指标对应的数据的存储地址或者pfmParData01的值为所述上报指标对应的数据的存储地址，NSCF设备可以先根据该存储地址获取所述上报指标对应的数据，再根据本步骤上述过程进行计费处理。Optionally, when pfmParData01 contains the storage address of the data corresponding to the reporting indicator or the value of pfmParData01 is the storage address of the data corresponding to the reporting indicator, the NSCF device can first obtain the data corresponding to the reporting indicator according to the storage address. , and then perform charging processing according to the above process of this step.

步骤313：NSCF设备向NSMF设备返回NS计费更新响应。Step 313: The NSCF device returns an NS accounting update response to the NSMF device.

可选地，所述NS计费更新响应中可以包含指示所述NS计费更新请求得到成功处理的信息，例如：“200OK”。Optionally, the NS charging update response may include information indicating that the NS charging update request has been successfully processed, for example: "200 OK".

应理解，步骤313可以在步骤312之前执行，图3A所示步骤的顺序只是一种示例，并非时序上的限定。It should be understood that step 313 may be performed before step 312 , and the sequence of the steps shown in FIG. 3A is only an example, and is not limited in timing.

步骤310-步骤313的过程为NSMF设备根据RPC中的上报参数自主上报性能指标对应的数据的过程，可以多次执行；NSMF设备可以根据所述RPC01中的开始条件、结束条件和获取方式等上报参数确定具体执行的次数，例如，可以根据开始条件中的开始时间、结束条件中的结束时间以及获取方式中的上报周期，确定总的执行次数。由于PPRO执行期间，NSCCF设备可以对其进行管理(变更或结束)，因此，所述确定的执行次数并不固定，具体可参见后续步骤319、步骤322和步骤327及其相关步骤中的描述。The process of step 310-step 313 is a process in which the NSMF device autonomously reports the data corresponding to the performance index according to the reporting parameters in the RPC, which can be performed multiple times; the NSMF device can report according to the start condition, end condition and acquisition method in the RPC01. The parameter determines the specific execution times. For example, the total execution times can be determined according to the start time in the start condition, the end time in the end condition, and the reporting period in the acquisition method. Since the NSCCF device can manage (change or end) the PPRO during its execution, the determined execution times are not fixed. For details, please refer to the descriptions in the subsequent steps 319, 322 and 327 and their related steps.

步骤314：NSMF设备确定结束条件满足。Step 314: The NSMF device determines that the end condition is satisfied.

具体地，NSMF设备可以根据RPC01中的结束条件“20190331:23:59:59结束”，在2019年3月31日23:59:59时确定结束条件满足。Specifically, the NSMF device may determine that the end condition is satisfied at 23:59:59 on March 31, 2019 according to the end condition "20190331:23:59:59 end" in RPC01.

RPC01中，上报条件不限于“到达某个时间点”，也可以是其他条件，例如，“某个事件发生”(假设RPC01中的上报指标为“时延”)，则NSMF设备确定上报条件满足的方法将有所不同，本申请实施例不一一赘述。In RPC01, the reporting condition is not limited to "a certain time point", but can also be other conditions, for example, "a certain event occurs" (assuming the reporting indicator in RPC01 is "delay"), then the NSMF device determines that the reporting condition is satisfied The method will be different, and the embodiments of the present application will not describe them one by one.

RPC01中，开始条件不限于“到达某个时间点”，也可以是其他条件，例如，“某个事件发生”，则NSMF设备确定开始条件满足的方法将有所不同，本申请实施例不一一赘述。In RPC01, the start condition is not limited to "reach a certain time point", but can also be other conditions, for example, "a certain event occurs", then the method for the NSMF device to determine that the start condition is satisfied will be different, and the embodiments of this application are different. One more elaboration.

步骤315：NSMF设备向NSCF设备发送NS计费结束请求，所述NS计费结束请求中包含CSId01和上报指标对应的数据pfmParData02。Step 315: The NSMF device sends an NS charging end request to the NSCF device, where the NS charging end request includes CSId01 and data pfmParData02 corresponding to the reporting indicator.

具体地，NSMF设备根据步骤314所确定的结束条件满足，确定需要结束所述PPRO，包括向NSCF设备发送NS计费结束请求，停止获取RPC01中的上报指标对应的数据等，其中所述NS计费结束请求中包含CSId01。当NSMF设备确定有RPC01中的上报指标对应的数据尚未上报，则可以在所述PPRO结束前将其上报给NSCF设备，为此，可以在所述NS计费结束请求中进一步包含pfmParData02，如此，pfmParData02在所述NS计费结束请求中是可选的。Specifically, the NSMF device determines that the PPRO needs to be terminated according to the termination condition determined in step 314, including sending an NS accounting termination request to the NSCF device, and stopping the acquisition of data corresponding to the reporting indicators in RPC01, etc., wherein the NS accounting CSId01 is included in the end of fee request. When the NSMF device determines that the data corresponding to the reporting indicator in RPC01 has not been reported, it can report it to the NSCF device before the end of the PPRO. For this reason, the NS charging end request can further include pfmParData02, so, pfmParData02 is optional in the NS charging end request.

当一个PPRO中有多个NSI对应的上报指标对应的数据需要上报时，为了确保不同NSI的计费正确，不同NSI对应的获取和上报操作的结束可以分开进行，即：针对多个NSI，NSMF设备可以逐一确定对应的结束条件满足，再向NSCF设备发送NS计费结束请求，其中包含相应的CSId/NSIId，并停止获取相应NSI的上报指标对应的数据。When the data corresponding to the reporting indicators corresponding to multiple NSIs needs to be reported in a PPRO, in order to ensure the correct charging of different NSIs, the acquisition and reporting operations corresponding to different NSIs can be completed separately, that is, for multiple NSIs, NSMF The device may determine that the corresponding end conditions are satisfied one by one, and then send the NS charging end request to the NSCF device, which includes the corresponding CSId/NSIId, and stop acquiring the data corresponding to the reporting indicator of the corresponding NSI.

NSMF设备根据RPC01中的结束条件满足确定需要结束所述PPRO，是其确定需要结束所述PPRO的实现方式之一(另一种方式是根据从NSCCF设备接收到的删除PPRO请求或结束指示，具体参见步骤327、328等)。The NSMF device determines that the PPRO needs to be terminated according to the termination conditions in RPC01, which is one of the implementation modes for determining that the PPRO needs to be terminated (another way is to delete the PPRO request or termination instruction received from the NSCCF device, specifically See steps 327, 328, etc.).

步骤316：NSCF设备进行计费处理并释放计费会话CS01。Step 316: The NSCF device performs charging processing and releases the charging session CS01.

具体地，NSCF设备接收步骤315中的所述NS计费结束请求并从中解析出计费会话标识CSId01和所述上报指标对应的数据pfmParData02，再基于pfmParData02进行计费处理，具体可以参见步骤312，进而根据CSId01确定相应的计费会话CS01，释放或者回收CS01对应的计算资源。Specifically, the NSCF device receives the NS charging end request in step 315, parses the charging session identifier CSId01 and the data pfmParData02 corresponding to the reporting indicator, and then performs charging processing based on pfmParData02. For details, refer to step 312. Further, the corresponding charging session CS01 is determined according to CSId01, and the computing resources corresponding to CS01 are released or reclaimed.

应理解，由于pfmParData02在步骤315中的所述NS计费结束请求中是可选的，当其在所述NS计费结束请求中不出现时，NSCF设备基于pfmParData02进行的计费处理也将省略。It should be understood that since pfmParData02 is optional in the NS charging end request in step 315, when it does not appear in the NS charging end request, the charging process performed by the NSCF device based on pfmParData02 will also be omitted .

由于NSCF设备可能同时接收多个NSI的性能指标对应的数据，并行进行计费处理，上述基于CSId01有针对性地释放或者回收计算资源，有助于保持NSCF设备上计费处理事务的稳定性，同时有助于提高NSCF设备整体的可用性和稳定性。Since NSCF equipment may receive data corresponding to multiple NSI performance indicators at the same time and perform billing processing in parallel, the above-mentioned targeted release or recovery of computing resources based on CSId01 helps to maintain the stability of billing processing transactions on NSCF equipment. At the same time, it helps to improve the overall availability and stability of NSCF equipment.

步骤317：NSCF设备向NSMF设备返回NS计费结束响应。Step 317: The NSCF device returns an NS charging end response to the NSMF device.

可选地，所述NS计费结束响应中包含指示所述NS计费结束请求得到成功处理的信息，例如：“200OK”。Optionally, the NS charging end response includes information indicating that the NS charging end request has been successfully processed, for example: "200 OK".

步骤318：NSMF设备停止获取上报指标对应的数据。Step 318: The NSMF device stops acquiring the data corresponding to the reported indicator.

具体地，NSMF设备停止获取NSIId01对应的网络切片实例的带宽数据。Specifically, the NSMF device stops acquiring the bandwidth data of the network slice instance corresponding to NSIId01.

应理解，步骤316也可以在步骤317之后进行，步骤318也可以在步骤315之前进行。图3A所示步骤的顺序只是一种示例，并非时序上的限定。It should be understood that step 316 can also be performed after step 317 , and step 318 can also be performed before step 315 . The sequence of the steps shown in FIG. 3A is only an example, and is not limited in timing.

步骤314-步骤318的过程为NSMF设备根据RPC中的上报参数自主结束上报性能指标对应的数据的过程，该自主结束的机制，可以减少NSCCF设备与NSMF设备之间的交互次数。The process from step 314 to step 318 is that the NSMF device autonomously ends the process of reporting the data corresponding to the performance index according to the reporting parameters in the RPC. This autonomous termination mechanism can reduce the number of interactions between the NSCCF device and the NSMF device.

步骤319：NSCCF设备向NSMF设备发送变更PPRO请求，所述变更PPRO请求中包含PPROId01或CSId01和RPC011。Step 319: The NSCCF device sends a PPRO change request to the NSMF device, where the PPRO change request includes PPROId01 or CSId01 and RPC011.

如果所述PPRO中仅上报一个NSI的性能指标对应的数据，则所述变更PPRO请求可以包含PPROId01与RPC011，也可以包含CSId01与RPC011，均表示要将所述一个NSI对应的上报操作的上报参数集更新为RPC011，RPC011为不同于RPC01的上报参数集；If only the data corresponding to the performance index of one NSI is reported in the PPRO, the change PPRO request may include PPROId01 and RPC011, and may also include CSId01 and RPC011, both of which indicate the reporting parameters of the reporting operation corresponding to the one NSI The set is updated to RPC011, and RPC011 is a reporting parameter set different from RPC01;

如果PPRO中上报多个NSI的性能指标对应的数据，所述变更PPRO请求中可以包含PPROId01与RPC011，表示需要更新所述多个NSI的上报操作的上报参数集(假设针对所述多个NSI的上报操作共用相同的上报参数集)，也可以包含多组CSId与RPC的对应关系或者NSIId与RPC的对应关系，表示需要为所述多个NSI分别更新上报参数集。例如，一个变更PPRO请求可以为：If the data corresponding to the performance indicators of multiple NSIs is reported in the PPRO, the PPRO change request may include PPROId01 and RPC011, indicating that the reporting parameter set of the reporting operation of the multiple NSIs needs to be updated (assuming that the data for the multiple NSIs The reporting operation shares the same reporting parameter set), and may also include the corresponding relationship between multiple groups of CSId and RPC or the corresponding relationship between NSIId and RPC, indicating that the reporting parameter sets need to be updated for the multiple NSIs respectively. For example, a change PPRO request could be:

或者为：or as:

应理解，NSCCF设备在本步骤之前可以先确定需要变更PPRO中的上报参数集RPC，例如，NSCCF设备可以基于客户订购信息的变更、运营商计费策略的变更等，确定需要变更PPRO中的RPC。It should be understood that the NSCCF device may determine that the reporting parameter set RPC in the PPRO needs to be changed before this step. For example, the NSCCF device may determine that the RPC in the PPRO needs to be changed based on the change of the customer's subscription information, the change of the operator's billing policy, etc. .

步骤320：NSMF设备更新RPC并基于新RPC执行PPRO。Step 320: The NSMF device updates the RPC and performs PPRO based on the new RPC.

具体地，NSMF设备接收所述变更PPRO请求，从中解析出PPROId01/CSId01和RPC011，用所述RPC011更新与PPROId01或CSId01相应的上报操作对应的RPC，并基于更新的RPC执行上报操作，具体上报操作可以参见步骤310-步骤318的过程。Specifically, the NSMF device receives the change PPRO request, parses out PPROId01/CSId01 and RPC011 from it, uses the RPC011 to update the RPC corresponding to the reporting operation corresponding to PPROId01 or CSId01, and performs the reporting operation based on the updated RPC, the specific reporting operation See steps 310-318 for the process.

步骤321：NSMF设备向NSCCF设备返回变更PPRO响应。Step 321: The NSMF device returns a change PPRO response to the NSCCF device.

可选地，所述变更PPRO响应中可以包含指示所述变更PPRO请求得到成功处理的信息，例如：“200OK”。Optionally, the change PPRO response may include information indicating that the change PPRO request has been successfully processed, for example: "200 OK".

应理解，步骤321可以在步骤321之前进行。It should be understood that step 321 may be performed before step 321 .

步骤319-步骤321的过程是可选过程，是NSMF设备被动变更PPRO的过程，将影响或者改变此前根据RPC01确定的上报过程，例如将改变上报的次数、时间间隔等。The process from step 319 to step 321 is an optional process, which is the process of passively changing the PPRO by the NSMF device, which will affect or change the reporting process previously determined according to RPC01, such as changing the number of reporting times, time interval, etc.

步骤322：NSCCF设备向NSMF设备发送变更PPRO请求，所述变更PPRO请求中包含PPROId01或CSId01，以及立即上报指示rptImd。Step 322: The NSCCF device sends a PPRO change request to the NSMF device, where the PPRO change request includes PPROId01 or CSId01, and an immediate reporting indication rptImd.

如果所述PPRO中仅上报一个NSI的性能指标对应的数据，则所述变更PPRO请求可以包含PPROId01与rptImd，也可以包含CSId01与rptImd，均表示需要将所述一个NSI的性能指标对应的数据上报到NSCF设备；If only the data corresponding to one NSI performance indicator is reported in the PPRO, the PPRO change request may include PPROId01 and rptImd, or CSId01 and rptImd, both of which indicate that the data corresponding to the one NSI performance indicator needs to be reported to the NSCF device;

如果PPRO中上报多个NSI的性能指标对应的数据，所述变更PPRO请求中可以包含PPROId01与rptImd，表示需要将所述多个NSI的性能指标对应的数据上报到NSCF设备，也可以包含多个CSId与rptImd或者包含多个NSIId与rptImd，表示需要将这些CSId或NSIId对应的NSI的性能指标对应的数据上报到NSCF设备。例如，一个变更PPRO请求可以为：If the data corresponding to multiple NSI performance indicators is reported in the PPRO, the PPRO change request may include PPROId01 and rptImd, indicating that the data corresponding to the multiple NSI performance indicators needs to be reported to the NSCF device, and may also include multiple The CSId and rptImd or multiple NSIId and rptImd are included, indicating that the data corresponding to the NSI performance index corresponding to these CSId or NSIId needs to be reported to the NSCF device. For example, a change PPRO request could be:

用于表示将计费会话标识分别为csid01、csid02和csid03的NSI的上报指标对应的数据上报给NSCF设备，csid01、csid02和csid03分别对应一个NSI。It is used to indicate that the data corresponding to the reporting indicators of the NSI with the charging session identifiers csid01, csid02 and csid03 are reported to the NSCF device, and csid01, csid02 and csid03 respectively correspond to an NSI.

或者为：or as:

用于表示将PPROId01对应的PPRO中所有NSI对应的上报指标对应的数据上报给NSCF设备。It is used to indicate that the data corresponding to the reporting indicators corresponding to all NSIs in the PPRO corresponding to PPROId01 is reported to the NSCF device.

或者为：or as:

用于表示将网络切片实例标识分别为nsiid01、nsiid02和nsiid03的NSI的上报指标对应的数据上报给NSCF设备。It is used to indicate that the data corresponding to the reporting indicators of the NSI whose network slice instance identifiers are respectively nsiid01, nsiid02, and nsiid03 are reported to the NSCF device.

应理解，NSCCF设备在本步骤之前可以先确定需要NSMF设备将所述NSI的性能指标对应的数据上报到NSCF设备，例如，NSCCF设备可以基于客户临时提出的查询账单的需求、运营商临时提出的输出账单的需求等，作出上述判断。It should be understood that the NSCCF device may first determine that the NSMF device needs to report the data corresponding to the performance index of the NSI to the NSCF device before this step. The demand for output bills, etc., make the above judgments.

应理解，所述立即上报指示rptImd也可以通过消息名称来体现，也就是说，如果本步骤的请求消息名称改为其他名称，以至于可以体现立即上报的指示(或者默认体现立即上报的指示)，则该请求消息中也可以不携带所述rptImd。It should be understood that the immediate reporting instruction rptImd can also be represented by the message name, that is, if the name of the request message in this step is changed to another name, so that the immediate reporting instruction can be represented (or the immediate reporting instruction is represented by default) , the rptImd may not be carried in the request message.

步骤323：NSMF设备向NSCF设备发送NS计费更新请求，所述NS计费更新请求中包含CSId01、pfmParData03和rptRsn02。Step 323: The NSMF device sends an NS accounting update request to the NSCF device, where the NS accounting update request includes CSId01, pfmParData03 and rptRsn02.

具体地，NSMF设备根据NSCCF设备发送的上报指示(rptImd)确定需要将所述RPC中的上报指标对应的数据上报到NSCF设备，向NSCF设备发送所述NS计费更新请求，所述NS计费更新请求中包含CSId01、pfmParData03he rptRsn02。本步骤与步骤311类似，但pfmParData03不同于pfmParData01(不同时刻下所述NSI的性能指标对应的数据)，上报原因rptRsn02不同于rptRsn01，为“NSCCF设备触发”。Specifically, the NSMF device determines that the data corresponding to the reporting indicator in the RPC needs to be reported to the NSCF device according to the reporting indication (rptImd) sent by the NSCCF device, and sends the NS accounting update request to the NSCF device, and the NS accounting The update request includes CSId01, pfmParData03, and rptRsn02. This step is similar to step 311, but pfmParData03 is different from pfmParData01 (data corresponding to the NSI performance indicators at different times), and the reporting reason rptRsn02 is different from rptRsn01, which is "NSCCF device trigger".

NSMF设备根据从NSCCF设备接收到的rptImd确定需要将所述RPC中上报指标对应的数据上报到NSCF设备，是其确定需要将所述RPC中上报指标对应的数据上报到NSCF设备的实现方式之一(另一种方式是确定RPC中的上报条件满足，具体参见步骤310等)。The NSMF device determines, according to the rptImd received from the NSCCF device, that the data corresponding to the reported indicator in the RPC needs to be reported to the NSCF device, which is one of the implementation manners in which it determines that the data corresponding to the reported indicator in the RPC needs to be reported to the NSCF device. (Another way is to determine that the reporting conditions in the RPC are satisfied, see step 310 for details).

应理解，本步骤中的NS计费更新请求与步骤311中NS计费更新请求的消息名称相同，为了使NSCF设备能区分触发上报所述上报指标对应的数据的原因(简称上报原因)，并根据上报原因的不同进行不同的计费处理(例如，在上报原因为“上报条件满足”时，NSCF设备进行的计费处理为将上报指标对应的数据写入计费话单，而在上报原因为“NSCCF设备触发”时，NSCF设备进行的计费处理为将上报指标对应的数据写入计费话单且触发账单系统输出账单)，而在这两个消息中分别携带了rptRsn01和rptRsn02；但如果这两个消息采用不同的名称，从而借助消息名称即可区分触发上报的原因，则也可以不在这两个消息中携带rptRsn01和rptRsn02。It should be understood that the NS charging update request in this step is the same as the message name of the NS charging update request in step 311, so that the NSCF device can distinguish the reason (reporting reason for short) that triggers the reporting of the data corresponding to the reporting indicator, and Different charging processing is performed according to different reporting reasons (for example, when the reporting reason is "reporting condition is satisfied", the charging processing performed by the NSCF device is to write the data corresponding to the reporting indicator into the charging CDR, and When it is "NSCCF device trigger", the charging processing performed by the NSCF device is to write the data corresponding to the reported indicator into the charging bill and trigger the billing system to output the bill), and these two messages carry rptRsn01 and rptRsn02 respectively; However, if the two messages have different names, so that the reason for triggering the reporting can be distinguished by the message names, rptRsn01 and rptRsn02 may not be carried in the two messages.

步骤324：NSCF设备进行计费处理。Step 324: The NSCF device performs charging processing.

具体地，NSCF设备接收所述NS计费更新请求，并从中解析出CSId01、pfmParData03和rptRsn02，再基于CSId01、pfmParData03和rptRsn02进行计费处理，例如，将pfmParData03(带宽采样值)记入CSId01对应计费话单中，由于上报原因rptRsn02为“NSCCF设备触发”，其意味着需要输出相应的计费账单，则NSCF设备可触发账单系统输出计费账单。NSCF设备也可以进一步结合客户订购时与运营商之间确定的计费规则(包括网络切片性能指标对应的数据，如其统计值，与计费方法的对应关系)，计算相应网络切片实例的费用。NSCF设备可以从订购实体或者NSCCF设备获取相应网络切片实例对应的计费规则。NSCF设备也可以在永久性存储介质中存储所述计费规则，以便在重启或故障恢复后继续使用所述计费规则。Specifically, the NSCF device receives the NS charging update request, parses out CSId01, pfmParData03 and rptRsn02 from it, and then performs charging processing based on CSId01, pfmParData03 and rptRsn02, for example, records pfmParData03 (bandwidth sample value) into the corresponding accounting of CSId01 In the bill of charges, rptRsn02 is "triggered by the NSCCF device" due to the reporting reason, which means that the corresponding billing bill needs to be output, and the NSCF device can trigger the billing system to output the billing bill. The NSCF device can also further calculate the cost of the corresponding network slice instance in combination with the charging rules determined between the customer and the operator (including the data corresponding to the network slice performance indicators, such as its statistical value and the corresponding relationship with the charging method). The NSCF device may obtain the charging rule corresponding to the corresponding network slice instance from the ordering entity or the NSCCF device. The NSCF device may also store the charging rules in a persistent storage medium, so as to continue to use the charging rules after restart or failure recovery.

根据上报的pfmParData03和rptRsn02的不同，计费处理方式有所不同，本申请实施例不一一赘述。According to the difference between the reported pfmParData03 and rptRsn02, the charging processing methods are different, and the embodiments of this application will not describe them one by one.

步骤325：NSCF设备向NSMF设备返回NS计费更新响应。Step 325: The NSCF device returns an NS accounting update response to the NSMF device.

可选地，所述NS计费更新响应中可以包含指示所述NS计费更新请求得到成功处理的信息，例如：“200OK”。Optionally, the NS charging update response may include information indicating that the NS charging update request has been successfully processed, for example: "200 OK".

应理解，步骤324可以在步骤325之后进行。It should be understood that step 324 may be performed after step 325 .

步骤326：NSMF设备向NSCCF设备返回变更PPRO响应。Step 326: The NSMF device returns a change PPRO response to the NSCCF device.

可选地，所述变更PPRO响应中可以包含指示所述变更PPRO请求得到成功处理的信息，例如：“200OK”。Optionally, the change PPRO response may include information indicating that the change PPRO request has been successfully processed, for example: "200 OK".

步骤322-步骤326的过程是可选过程，为NSMF设备被动上报NSI的性能指标对应的数据的过程。The processes from step 322 to step 326 are optional processes, and are processes in which the NSMF device passively reports data corresponding to the NSI performance index.

步骤327：NSCCF设备向NSMF设备发送删除PPRO请求，所述删除PPRO请求中包含PPROId01或CSId01。Step 327: The NSCCF device sends a PPRO deletion request to the NSMF device, where the PPRO deletion request includes PPROId01 or CSId01.

如果所述PPRO中仅上报一个NSI的性能指标对应的数据，则所述删除PPRO请求可以包含PPROId01，也可以包含CSId01，均表示要结束所述一个NSI的上报操作；If only the data corresponding to the performance index of one NSI is reported in the PPRO, the PPRO deletion request may include PPROId01 or CSId01, both of which indicate that the reporting operation of the one NSI is to be terminated;

如果PPRO中上报多个NSI的性能指标对应的数据，所述删除PPRO请求中可以包含PPROId01，表示要结束所述多个NSI的上报操作，也可以包含多个CSId或者NSIId，表示需要结束这些CSId或NSIId对应的NSI的上报操作。例如，一个删除PPRO请求可以为：If the data corresponding to the performance indicators of multiple NSIs is reported in the PPRO, the delete PPRO request may include PPROId01, indicating that the reporting operation of the multiple NSIs is to be terminated, and may also include multiple CSIds or NSIIds, indicating that these CSIds need to be terminated Or the reporting operation of the NSI corresponding to the NSIId. For example, a delete PPRO request could be:

DeletePPRORequest{DeletePPRORequest{

"CSIIdList":"csid01|csid02|csid03" "CSIIdList":"csid01|csid02|csid03"

}}

用于表示结束计费会话标识分别为csid01、csid02和csid03的上报过程(含上报指标对应的数据的获取和上报)，csid01、csid02和csid03分别对应一个NSI。It is used to indicate the end of the reporting process of the charging session identifiers csid01, csid02 and csid03 (including the acquisition and reporting of data corresponding to the reporting indicators), and csid01, csid02 and csid03 respectively correspond to an NSI.

或者为：or as:

DeletePPRORequest{DeletePPRORequest{

"PPROId":"PPROId01" "PPROId":"PPROId01"

}}

用于表示结束PPROId01对应的PPRO中所有NSI对应的上报指标对应的数据的获取和上报操作。It is used to indicate that the acquisition and reporting operations of data corresponding to reporting indicators corresponding to all NSIs in the PPRO corresponding to PPROId01 are ended.

或者为：or as:

DeletePPRORequest{DeletePPRORequest{

"NSIIdList":"nsiid01|nsiid02|nsiid03" "NSIIdList":"nsiid01|nsiid02|nsiid03"

}}

用于表示结束网络切片实例标识分别为nsiid01、nsiid02和nsiid03的NSI对应的上报过程(含上报指标对应的数据的获取和上报)。It is used to indicate the end of the reporting process corresponding to the NSIs whose network slice instance identifiers are nsiid01, nsiid02, and nsiid03 respectively (including the acquisition and reporting of data corresponding to the reporting indicators).

应理解，NSCCF设备在本步骤之前可以先确定需要NSMF设备结束所述NSI的上报操作，例如，NSCCF设备可以基于客户的账户余额、订购变更，作出上述判断。It should be understood that the NSCCF device may determine that the NSMF device needs to end the NSI reporting operation before this step. For example, the NSCCF device may make the above judgment based on the customer's account balance and subscription changes.

步骤328：NSMF设备向NSCF设备发送NS计费结束请求，所述NS计费结束请求中包含CSId01和所述上报指标对应的数据pfmParData04。Step 328: The NSMF device sends an NS charging end request to the NSCF device, where the NS charging end request includes CSId01 and data pfmParData04 corresponding to the reported indicator.

该步骤与步骤315类似，pfmParData04也是可选的。其中，NSMF设备是根据步骤327中的删除PPRO请求确定(也可以在该消息中包含“结束PPRO”的指示信息，从而可以根据该指示信息确定)需要结束所述PPRO。This step is similar to step 315, pfmParData04 is also optional. Wherein, the NSMF device determines according to the PPRO deletion request in step 327 (the message may also include "end PPRO" indication information, so that it can be determined according to the indication information) that the PPRO needs to be terminated.

当一个PPRO中有多个NSI对应的上报指标对应的数据需要上报时，为了提高NSCCF设备对NSMF设备关于PPRO的控制力度，NSMF设备可以进行如下处理：When the data corresponding to the reporting indicators corresponding to multiple NSIs needs to be reported in a PPRO, in order to improve the NSCCF device's control over the NSMF device regarding the PPRO, the NSMF device can perform the following processing:

-在步骤327所述删除PPRO请求中包含PPRO的标识(如PPROId01)的情况下，NSMF设备可以结束所述多个NSI对应的获取和上报操作，即向NSCF设备发送多个NS计费结束请求，每一个NS计费结束请求包含相应的CSId/NSIId，停止获取所述多个NSI的上报指标对应的数据；- In the case that the PPRO delete request in step 327 contains the PPRO identifier (eg PPROId01), the NSMF device can end the acquisition and reporting operations corresponding to the multiple NSIs, that is, send multiple NS charging end requests to the NSCF device , each NS charging end request includes the corresponding CSId/NSIId, and stops acquiring the data corresponding to the reporting indicators of the multiple NSIs;

-在步骤327所述删除PPRO请求中包含单个计费会话标识(如CSId01)或单个网络切片实例标识(如NSIId01)，NSMF设备可以结束该单个计费会话标识或单个网络切片实例标识对应的NSI所对应的获取和上报操作，即向NSCF设备发送NS计费结束请求，其中包含相应的CSId/NSIId，并停止获取相应NSI的上报指标对应的数据，PPRO中其他NSI对应的获取和上报操作不受影响。如果在步骤327所述删除PPRO请求中包含多个计费会话标识或多个网络切片实例标识，则对这些计费会话标识或网络切片实例标识逐一分别执行以上操作。- The deletion PPRO request in step 327 contains a single charging session identifier (eg CSId01) or a single network slice instance identifier (eg NSIId01), and the NSMF device can end the NSI corresponding to the single charging session identifier or single network slice instance identifier The corresponding acquisition and reporting operations are to send an NS charging end request to the NSCF device, which includes the corresponding CSId/NSIId, and stop acquiring the data corresponding to the reporting indicators of the corresponding NSI. The acquisition and reporting operations corresponding to other NSIs in PPRO are not Affected. If the deletion PPRO request in step 327 contains multiple charging session identifiers or multiple network slice instance identifiers, the above operations are performed on these charging session identifiers or network slice instance identifiers one by one.

NSMF设备根据NSCCF设备发送的删除PPRO请求或“结束PPRO”指示信息确定需要结束所述PPRO，是其确定需要结束所述PPRO的实现方式之一(另一种方式是根据RPC01中的结束条件满足，具体参见步骤314、315等)。The NSMF device determines that the PPRO needs to be terminated according to the delete PPRO request sent by the NSCCF device or the "end PPRO" indication information, which is one of the implementation ways for it to determine that the PPRO needs to be terminated (another way is to satisfy the termination condition according to RPC01). , see steps 314, 315, etc. for details).

步骤329：NSCF设备进行计费处理并释放计费会话CS01。Step 329: The NSCF device performs charging processing and releases the charging session CS01.

该步骤与步骤316类似，基于pfmParData04的计费处理也是可选的。This step is similar to step 316, and the charging process based on pfmParData04 is also optional.

步骤330：NSCF设备向NSMF设备发送NS计费结束响应。Step 330: The NSCF device sends an NS accounting end response to the NSMF device.

该步骤与步骤317类似This step is similar to step 317

步骤331：NSMF设备停止获取上报指标对应的数据。Step 331: The NSMF device stops acquiring the data corresponding to the reporting indicator.

该步骤与步骤318类似。This step is similar to step 318.

应理解，步骤331可以在步骤328之前进行，步骤329可以在步骤330之后进行。It should be understood that step 331 may be performed before step 328 , and step 329 may be performed after step 330 .

步骤332：NSMF设备向NSCCF设备返回删除PPRO响应。Step 332: The NSMF device returns a delete PPRO response to the NSCCF device.

可选地，所述删除PPRO响应中可以包含指示所述删除PPRO请求得到成功处理的信息，例如：“200OK”。Optionally, the PPRO deletion response may include information indicating that the PPRO deletion request has been successfully processed, for example: "200 OK".

应理解，上述消息的名称，如创建PPRO请求/响应、更新PPRO请求/响应、删除PPRO请求/响应、NS计费初始请求/响应、NS计费更新请求/响应、NS计费结束请求/响应等，均是示例性消息名称，本申请实施例不限定这些消息的名称。例如，可以用“第一PPRO管理请求/响应”、“第二PPRO管理请求/响应”……代替“创建PPRO请求/响应”、“更新PPRO请求/响应”……可以用“第一计费请求/响应”、“第二计费请求/响应”……代替“NS计费初始请求/响应”、“NS计费更新请求/响应”……。It should be understood that the names of the above messages, such as Create PPRO Request/Response, Update PPRO Request/Response, Delete PPRO Request/Response, NS Billing Initial Request/Response, NS Billing Update Request/Response, NS Billing End Request/Response etc., are all exemplary message names, and the embodiments of the present application do not limit the names of these messages. For example, "first PPRO management request/response", "second PPRO management request/response"... may be used instead of "create PPRO request/response", "update PPRO request/response"... may be replaced by "first billing request/response", "second charging request/response"... instead of "NS charging initial request/response", "NS charging update request/response"....

图3A对应的对网络资源进行计费处理方法，使得NSCCF设备可以下发面向单个NSI的上报操作(一个PPRO中上报一个NSI的性能指标对应的数据)，也可以下发面向多个NSI的上报操作(一个PPRO中上报多个NSI的性能指标对应的数据)给NSMF设备执行，并且既可以以PPRO为粒度进行管理，也可以以NSI或者计费会话为粒度，管理PPRO中的一部分(针对某个NSI的上报过程)进行管理，提高了NSCCF设备对网络切片实例进行计费处理的控制力度。此外，NSMF设备和NSCF设备之间基于会话进行上报(接收)，NSMF设备和/或NSCF设备(指任一方或双方)可以在不同上报操作之间重用计算资源，节约创建相应计算资源的时间，有利于提高NSMF设备和/或NSCF设备的运行效率。Fig. 3A corresponds to the charging processing method for network resources, so that the NSCCF device can issue a reporting operation for a single NSI (the data corresponding to the performance index of one NSI reported in one PPRO), and can also issue reporting for multiple NSIs The operation (data corresponding to multiple NSI performance indicators reported in one PPRO) is executed by the NSMF device, and can be managed either with PPRO as the granularity, or with NSI or charging session as the granularity to manage a part of the PPRO (for a certain The reporting process of each NSI) is managed, which improves the control strength of the NSCCF device for the charging processing of the network slice instance. In addition, the reporting (receiving) between the NSMF device and the NSCF device is based on the session, and the NSMF device and/or the NSCF device (referring to either or both parties) can reuse computing resources between different reporting operations, saving the time for creating corresponding computing resources, It is beneficial to improve the operation efficiency of NSMF equipment and/or NSCF equipment.

除了采用会话上报的方式外，还可以采用独立上报的方式，具体可参见图3B。In addition to the session reporting method, an independent reporting method can also be used, as shown in FIG. 3B for details.

图3B为本申请实施例提供的对网络资源进行计费处理的又一方法流程图，与图3A的方法流程相比，该方法流程中NSMF设备与NSCF设备之间采用独立上报方式进行上报，具体包括如下步骤：FIG. 3B is a flowchart of another method for performing charging processing on network resources provided by the embodiment of the present application. Compared with the method flowchart of FIG. 3A , in the method flowchart, the NSMF device and the NSCF device use an independent reporting method for reporting, Specifically include the following steps:

步骤350-步骤354：与步骤301-步骤305类似，不再赘述。步骤350所确定的RPC02中的上报方式取值为“独立上报”。Step 350-Step 354: are similar to Step 301-Step 305, and are not repeated here. The value of the reporting method in RPC02 determined in step 350 is "independent reporting".

步骤355-步骤358：与步骤310-步骤313的过程相比，其区别在于步骤356的NS计费请求中用网络切片实例的标识NSIId02代替步骤311的NS计费更新请求中的计费会话标识CSId01，NSMF设备每次向NSCF设备发送NS计费请求，NSCF设备创建或分配新的计算资源用于计费处理等，相应地，NSCF进行计费处理后，新创建或分配计算资源也在计费处理结束后及时释放或回收。Step 355-Step 358: Compared with the process of Step 310-Step 313, the difference is that the ID NSIId02 of the network slice instance is used in the NS charging request in Step 356 to replace the charging session ID in the NS charging update request in Step 311 CSId01, every time the NSMF device sends an NS accounting request to the NSCF device, the NSCF device creates or allocates new computing resources for accounting processing, etc. Correspondingly, after the NSCF performs the accounting processing, the newly created or allocated computing resources are also counted. It shall be released or recycled in time after the fee processing is over.

步骤359-步骤361：与步骤319-步骤321的过程相比，其区别在于步骤359的变更PPRO请求中用网络切片实例的标识NSIId02代替步骤319的变更PPRO请求中的计费会话标识CSId01。Step 359-Step 361: Compared with the process of Step 319-Step 321, the difference is that in the change PPRO request in step 359, the network slice instance identifier NSIId02 is used instead of the charging session identifier CSId01 in the change PPRO request in step 319.

步骤362-步骤366：与步骤322-步骤326的过程相比，其区别在于:步骤356的变更PPRO请求中，用网络切片实例的标识NSIId02代替步骤322的变更PPRO请求中的计费会话标识CSId01；步骤363的NS计费请求中,用网络切片实例的标识NSIId02代替步骤323的NS计费更新请求中的计费会话标识CSId01；且相应地，NSCF设备创建新的计算资源用于接收所述NS计费请求并进行计费处理(而不是重用此前创建或分配的计算资源)。Step 362-Step 366: Compared with the process of Step 322-Step 326, the difference is: in the change PPRO request in step 356, the network slice instance identifier NSIId02 is used to replace the charging session identifier CSId01 in the change PPRO request in step 322. ; In the NS charging request of step 363, replace the charging session identifier CSId01 in the NS charging update request of step 323 with the identifier NSIId02 of the network slice instance; and correspondingly, the NSCF device creates a new computing resource for receiving the described NS bills requests and performs billing processing (rather than reusing previously created or allocated computing resources).

步骤367-步骤372：与步骤327-步骤332的过程相比，其区别在于：步骤367的删除PPRO请求中，用网络切片实例的标识NSIId02代替步骤327的删除PPRO请求中的计费会话标识CSId01；步骤368的NS计费请求中,用网络切片实例的标识NSIId02代替步骤328的NS计费更新请求中的计费会话标识CSId01；且相应地，NSCF设备无需执行释放计费会话的操作。可选地，步骤368中还可以包含上报原因rptRsn05，为“上报结束”，以指示NSCF设备进行响应的计费处理，如触发账单系统输出账单等。Step 367-Step 372: Compared with the process of Step 327-Step 332, the difference is: in the delete PPRO request in Step 367, the network slice instance ID NSIId02 is used to replace the charging session ID CSId01 in the PPRO delete request in Step 327. ; In the NS charging request of step 368, the identifier NSIId02 of the network slice instance is used to replace the charging session identifier CSId01 in the NS charging update request of step 328; and accordingly, the NSCF device does not need to perform the operation of releasing the charging session. Optionally, step 368 may further include the reporting reason rptRsn05, which is "reporting end", to instruct the NSCF device to perform a responsive charging process, such as triggering the billing system to output bills.

图3B对应的对网络资源进行计费处理方法，使得NSMF设备和NSCF设备之间采用独立上报的方式进行上报(接收)，NSMF设备和/或NSCF设备可以在每次上报结束后及时释放或回收计算资源，避免在网络切片实例较多多时，占用NSMF设备和/或NSCF设备中过多的计算资源，有利于提高NSMF设备和/或NSCF设备的可用性和稳定性。The charging processing method for network resources corresponding to FIG. 3B enables the NSMF device and the NSCF device to report (receive) in an independent reporting manner, and the NSMF device and/or the NSCF device can release or recycle in time after each report ends. Computational resources are used to avoid occupying too many computing resources in the NSMF device and/or the NSCF device when there are many network slice instances, which is beneficial to improve the availability and stability of the NSMF device and/or the NSCF device.

为提高管理效率，上述上报参数集RPC可以在多个网络切片实例对应的上报操作之间进行共享，为此，可以在NSCCF设备与NSMF设备之间维护上报参数集模板RPCT，以便后续重用。图4为本申请实施例提供的管理上报参数集模板的方法流程图，其中RPCT管理客户端可以为图1中的NSCCF设备101，也可以是其他设备，RPCT管理服务器可以为图1中的NSMF设备103，也可以是其他设备，对此，本申请实施例不做限定。该方法流程具体包含如下步骤：To improve management efficiency, the above-mentioned reporting parameter set RPC can be shared among reporting operations corresponding to multiple network slice instances. To this end, the reporting parameter set template RCT can be maintained between the NSCCF device and the NSMF device for subsequent reuse. 4 is a flowchart of a method for managing and reporting a parameter set template provided by an embodiment of the present application, where the RPCT management client may be theNSCCF device 101 in FIG. 1 or other devices, and the RPCT management server may be the NSMF in FIG. 1 Thedevice 103 may also be other devices, which are not limited in this embodiment of the present application. The method process specifically includes the following steps:

步骤401：RPCT管理客户端向RPCT管理服务器发送创建RPCT请求，其中携带待创建的RPCT。Step 401: The RPCT management client sends a request for creating an RPCT to the RPCT management server, which carries the RPCT to be created.

应理解RPCT本质上也是一种RPC。It should be understood that RPCT is also an RPC in nature.

步骤402：RPCT管理服务器存储所述RPCT。Step 402: The RPCT management server stores the RPCT.

具体地，RPCT管理服务器接收多数创建RPCT请求，从中解析出所述待创建的RPCT，并为所述RPCT分配唯一标识RPCTId，且存储所述待创建的RPCT。Specifically, the RPCT management server receives most of the RPCT creation requests, parses out the RPCT to be created, assigns a unique identifier RPCTId to the RPCT, and stores the RPCT to be created.

步骤403：RPCT管理服务器向RPCT管理客户端返回创建RPCT响应，所述创建RPCT响应中包含所述RPCTId。Step 403: The RPCT management server returns a create RPCT response to the RPCT management client, where the create RPCT response includes the RPCTId.

后续RPCT管理客户端，例如NSCCF设备可以仅向NSMF设备发送所述RPCTId，而不用发送所述RPCTId对应的整个RPCT，可以提高NSCCF设备与NSMF设备之间传输信息的效率。The subsequent RPCT management client, for example, the NSCCF device can only send the RPCTId to the NSMF device without sending the entire RCT corresponding to the RPCTId, which can improve the efficiency of information transmission between the NSCCF device and the NSMF device.

所述RPCTId还可以用于向RPCT管理客户端表明所述创建RPCT请求得到成功处理，所述RPCT已在所述RPCT管理服务器生效。The RPCTId can also be used to indicate to the RPCT management client that the request for creating an RPCT has been successfully processed, and that the RPCT has taken effect on the RPCT management server.

步骤404：RPCT管理客户端向RPCT管理服务器发送更新RPCT请求，所述更新RPCT请求中携带RPCTId和RPCTUpdtInfo。Step 404: The RPCT management client sends an update RPCT request to the RPCT management server, where the update RPCT request carries RPCTId and RPCTUpdtInfo.

其中RPCTId用于确定已有RPCT，RPCTUpdtInfo用于更新已有RPCT中的上报参数。The RPCTId is used to determine the existing RCT, and the RPCTUpdtInfo is used to update the reporting parameters in the existing RPCT.

应理解，在本步骤之前，RPCT管理客户端可以先确定需要对RPCT进行更新，例如，RPCT管理客户端可以根据运营商统一制定的计费策略的变更作出上述判断。例如，随着运营商提供的网络带宽能力的提高，针对eMBB类型的NSI的RPCT中关于带宽约束条件可以上调，以便NSMF设备执行针对该类型NSI的上报操作时，统一使用上调的带宽约束条件。It should be understood that, before this step, the RPCT management client may determine that the RPCT needs to be updated. For example, the RPCT management client may make the above judgment according to the change of the charging policy uniformly formulated by the operator. For example, with the improvement of network bandwidth capabilities provided by operators, the bandwidth constraints in the RPCT for eMBB-type NSIs can be increased, so that NSMF devices can uniformly use the increased bandwidth constraints when performing reporting operations for this type of NSI.

步骤405：RPCT管理服务器更新RPCT。Step 405: The RPCT management server updates the RPCT.

具体地，RPCT管理服务器接收所述更新RPCT请求，从中解析出RPCTId和RPCTUpdtInfo，并根据RPCTUpdtInfo更新RPCTId对应的RPCT中的上报参数。Specifically, the RPCT management server receives the update RPCT request, parses the RPCTId and RPCTUpdtInfo from the request, and updates the reporting parameters in the RPCT corresponding to the RPCTId according to the RPCTUpdtInfo.

步骤406：RPCT管理服务器向RPCT管理客户端返回更新RPCT响应。Step 406: The RPCT management server returns an update RPCT response to the RPCT management client.

可选地，所述更新RPCT响应中可以包含指示所述更新RPCT请求得到成功处理的信息，例如：“200OK”。Optionally, the update RPCT response may include information indicating that the update RPCT request has been successfully processed, for example: "200 OK".

应理解，RPCT的更新，可以不影响已经基于更新前的RPCT进行的上报操作。It should be understood that the update of the RPCT may not affect the reporting operation that has been performed based on the RPCT before the update.

为确保不同RPCT管理客户端上的所述RPCT内容一致，RPCT管理客户端或者RPCT管理服务器可以向其他RPCT管理客户端广播关于所述RPCT已被更新的消息。To ensure that the RPCT content on different RPCT management clients is consistent, the RPCT management client or the RPCT management server may broadcast a message that the RPCT has been updated to other RPCT management clients.

步骤407：RPCT管理客户端向RPCT管理服务器发送删除RPCT请求，所述删除RPCT请求中携带RPCTId。Step 407: The RPCT management client sends a delete RPCT request to the RPCT management server, where the delete RPCT request carries the RPCTId.

应理解，在此之前RPCT管理客户端可以先确定需要删除RPCT，例如根据运营商统一规划，当某个计费规则不再适用于任何网络切片的时候，其相应的RPCT将可以删除。It should be understood that before this, the RPCT management client can determine that the RPCT needs to be deleted. For example, according to the unified planning of the operator, when a certain charging rule is no longer applicable to any network slice, the corresponding RPCT can be deleted.

这里删除RPCT请求消息的名称，可以视为一种删除指示，用于指示RPCT管理服务器删除RPCTId对应的RPCT。如果所述删除请求RPCT请求消息改为其他名称，则RPCT管理客户端也可以在请求消息中包含删除指示。The name of the delete RPCT request message here can be regarded as a deletion instruction, used to instruct the RPCT management server to delete the RPCT corresponding to the RPCTId. If the deletion request RPCT request message is changed to another name, the RPCT management client may also include a deletion indication in the request message.

步骤408：RPCT管理服务器删除RPCT。Step 408: The RPCT management server deletes the RPCT.

具体地，RPCT管理服务器接收所述删除RPCT请求，并从中解析出RPCTId，根据所述删除请求，查找并删除所述RPCTId对应的RPCT。Specifically, the RPCT management server receives the delete RPCT request, parses out the RPCTId from it, and searches and deletes the RPCT corresponding to the RPCTId according to the delete request.

为确保所述RPCT不再被使用，RPCT管理客户端或者RPCT管理服务器可以向其他RPCT管理客户端广播关于所述RPCT已被删除的消息。To ensure that the RPCT is no longer used, the RPCT management client or the RPCT management server may broadcast a message to other RPCT management clients that the RPCT has been deleted.

步骤409：RPCT管理服务器向RPCT管理客户端返回删除RPC响应。Step 409: The RPCT management server returns a delete RPC response to the RPCT management client.

可选地，所述删除RPCT响应中可以包含指示所述删除RPCT请求得到成功处理的信息，例如：“200OK”。Optionally, the delete RPCT response may include information indicating that the delete RPCT request has been successfully processed, for example: "200 OK".

图4对应方法流程使得NSCCF设备和NSMF设备之间可以拥有共同理解、识别的RPCT，便于在NSCCF设备下发PPRO时使用。The corresponding method flow in FIG. 4 enables RCTs that are commonly understood and identified between the NSCCF device and the NSMF device, which is convenient for use when the NSCCF device issues the PPRO.

图5为本申请实施例提供的对网络资源进行计费处理的又一方法流程图，该方法流程基于图1所示的架构实现，其中NSCCF设备对应图1中的NSCCF设备101(包含图4所示RPCT管理客户端的功能)，NSMF设备对应图1中的NSMF设备103(包含图4所示RPCT管理服务器的功能)，NSCF设备对应图1中的NSCF设备102。该方法流程以更具体的例子说明NSCCF设备与NSMF设备如何使用将事先维护好的RPCT进行PPRO的创建和执行，具体包括如下步骤：FIG. 5 is a flowchart of another method for performing charging processing on network resources provided by an embodiment of the present application. The method flowchart is implemented based on the architecture shown in FIG. 1 , wherein the NSCCF device corresponds to theNSCCF device 101 in FIG. 1 (including FIG. 4 ). The NSMF device corresponds to theNSMF device 103 in FIG. 1 (including the function of the RPCT management server shown in FIG. 4 ), and the NSCF device corresponds to theNSCF device 102 in FIG. 1 . The method flow uses a more specific example to illustrate how the NSCCF device and the NSMF device use the RPCT that will be maintained in advance to create and execute the PPRO, which specifically includes the following steps:

步骤501：NSCCF设备确定NSI对应的RPCT的标识RPCTId、NSI特定的上报参数specRP。Step 501: The NSCCF device determines the RCT identifier RPCTId corresponding to the NSI and the NSI-specific reporting parameter specRP.

具体地，NSCCF设备可以根据NSI的网络切片类型或者其他计费因素，确定适用所述NSI的RPCT或相应的RPCTId。例如，NSCCF设备可以在本地存储一个网络切片类型到RPCTId的对应表，如表2所示，以便于根据NSI对应的网络切片类型，确定相应的RPCTId。Specifically, the NSCCF device may determine the RPCT or corresponding RPCTId applicable to the NSI according to the network slice type of the NSI or other charging factors. For example, the NSCCF device may locally store a correspondence table between network slice types and RPCTId, as shown in Table 2, so as to determine the corresponding RPCTId according to the network slice type corresponding to the NSI.

表2Table 2

网络切片类型Network slice typeRPCTRPCTeMBBeMBBRPCTId01RPCTId01uRLLCuRLLCRPCTId02RPCTId02mMTCmMTCRPCTId03RPCTId03

具体地，NSCCF设备可以根据客户的订购信息，确定NSI特定的上报参数specRP，所述specRP包括但不限于上述RPC中的开始条件和/或结束条件。Specifically, the NSCCF device may determine the NSI-specific reporting parameter specRP according to the customer's subscription information, where the specRP includes but is not limited to the start condition and/or the end condition in the above RPC.

步骤502：NSCCF设备向NSMF设备发送创建PPRO请求，所述创建PPRO请求中包含所述NSIId、所述RPCTId和所述specRP。Step 502: The NSCCF device sends a PPRO creation request to the NSMF device, where the PPRO creation request includes the NSIId, the RPCTId and the specRP.

步骤503：NSMF设备根据所述RPCTId和specRP形成PPRO对应的RPC。Step 503: The NSMF device forms an RPC corresponding to the PPRO according to the RPCTId and specRP.

具体地，NSMF设备接收所述创建PPRO请求，从中解析出所述NSIId、所述RPCTId和所述specRP，并基于所述RPCTId和所述specRP形成待创建或待执行的PPRO对应的RPC。例如，NSMF设备根据RPCTId检索出本地保存的相应的RPCT，将所述specRP与所述RPCT进行组合，形成所述RPC。举例如下：Specifically, the NSMF device receives the PPRO creation request, parses out the NSIId, the RPCTId, and the specRP, and forms an RPC corresponding to the PPRO to be created or executed based on the RPCTId and the specRP. For example, the NSMF device retrieves the corresponding RPCT stored locally according to the RPCTId, and combines the specRP with the RPCT to form the RPC. An example is as follows:

一个RPCT为：An RPCT is:

其中，值为“待定”的上报参数，其值需要结合NSI特定的上报参数specRP确定。The value of the reporting parameter is "to be determined", and its value needs to be determined in combination with the NSI-specific reporting parameter specRP.

一个specRP为：A specRP is:

其中，值为“参考模板”的字段，其值需要结合相应RPCT中的上报参数确定。Among them, the value of the field is "reference template", and its value needs to be determined in combination with the reporting parameters in the corresponding RPCT.

则NSMF设备可以将二者进行结合，形成RPC如下：Then the NSMF device can combine the two to form an RPC as follows:

NSMF设备可以存储RPC03，以便在NSMF设备重启或故障恢复之后继续根据RPC03执行PPRO，且实现PPRO的执行不受RPCT变更的影响(RPCT的变更参见图4对应方法流程)。The NSMF device can store the RPC03, so that after the NSMF device restarts or fails, the PPRO continues to be executed according to the RPC03, and the execution of the PPRO is not affected by the change of the RPCT (see the corresponding method flow in FIG. 4 for the change of the RPCT).

步骤504：NSMF设备根据所述RPC获取并上报NSI的性能指标对应的数据。Step 504: The NSMF device acquires and reports data corresponding to the NSI performance index according to the RPC.

该步骤可参见步骤304-步骤318的过程。For this step, please refer to the process from step 304 to step 318 .

步骤505：NSCCF设备改变或结束PPRO的执行。Step 505: The NSCCF device changes or ends the execution of the PPRO.

该步骤可参见步骤319-322的过程。This step can refer to the process of steps 319-322.

图5对应方法流程使得NSCCF设备可以向NSMF设备发送RPCTId，而不用发送RPCTId对应的整个RPCT，可以提高NSCCF设备与NSMF设备之间传输信息的效率，同时也有助于提高NSCCF设备在RPC采用上的统一管控能力。The corresponding method flow in Figure 5 enables the NSCCF device to send the RPCTId to the NSMF device without sending the entire RPCT corresponding to the RPCTId, which can improve the efficiency of information transmission between the NSCCF device and the NSMF device, and also help improve the NSCCF device's RPC adoption efficiency. Unified management and control capabilities.

The performance indicator reporting operation of NSI operates the reporting parameter set RPC of PPRO. Theordering entity 604 is a functional module, which can be deployed in a CRM (Customer Relationship Management, customer relationship management) server, or can be deployed in other devices.

图7为本申请实施例提供的对网络资源进行计费处理的又一方法流程图，该方法流程基于图6所示的架构实现，其中：NSCCF设备对应图6中的NSCCF设备101、NSMF设备对应图6中的NSMF设备103、订购实体对应图6中的订购实体604。该方法流程中，由NSCCF设备负责根据订购实体提供的信息确定PPRO的上报参数集RPC，由NSMF设备负责根据所述RPC执行所述PPRO，以向NSCF设备上报网络切片性能指标对应的数据，以使NSCF设备基于该数据进行计费处理，具体包括如下步骤：FIG. 7 is a flowchart of another method for performing charging processing on network resources provided by an embodiment of the present application. The method process is implemented based on the architecture shown in FIG. 6 , wherein the NSCCF device corresponds to theNSCCF device 101 and the NSMF device in FIG. 6 . Corresponding to theNSMF device 103 in FIG. 6 , the ordering entity corresponds to theordering entity 604 in FIG. 6 . In the method process, the NSCCF device is responsible for determining the reporting parameter set RPC of the PPRO according to the information provided by the ordering entity, and the NSMF device is responsible for executing the PPRO according to the RPC, so as to report the data corresponding to the network slice performance indicators to the NSCF device, so as to Making the NSCF device perform charging processing based on the data specifically includes the following steps:

步骤701：订购实体从客户接收网络切片订购请求。Step 701: The ordering entity receives a network slice ordering request from a customer.

具体地，客户(假设其标识为“1381234567”)可以通过其终端(如手机终端、笔记本电脑等，可以通过浏览器，也可以通过其他渠道)向订购实体提交网络切片订购请求，所述订购请求包含所述客户对网络切片的网络性能的需求信息，所述需求信息可以包括网络切片类型、网络切片性能指标的要求等。Specifically, a customer (assuming its identity is "1381234567") can submit a network slice order request to the ordering entity through its terminal (such as a mobile phone terminal, a laptop, etc., through a browser, or through other channels), and the order request Contains the client's requirement information on the network performance of the network slice, and the requirement information may include the network slice type, the requirements of the network slice performance indicators, and the like.

订购实体可以提供多种网络切片类型，使其显示在客户终端上供客户选择，例如，订购实体可以提供：eMBB类型(设备少但带宽要求大)、uRLLC类型(要求端到端时延极小)、mMTC类型(带宽小但设备数量极多)三种类型供客户选择。The ordering entity can provide a variety of network slice types, which can be displayed on the client terminal for customers to choose. For example, the ordering entity can provide: eMBB type (less equipment but large bandwidth requirements), uRLLC type (requires extremely small end-to-end delay) ), mMTC type (small bandwidth but a large number of devices) three types for customers to choose.

客户订购网络切片实例时，可以进一步指定网络切片性能指标的约束条件(该值可以是一个具体的值也可以是一个范围值)。例如：客户选择eMBB类型的网络切片，则可以进一步指定该网络切片实例的带宽高于1000G；客户选择uRLLC类型的网络切片，则可以进一步指定该网络切片实例的最大时延低于5毫秒；客户选择eMTC类型的网络切片，则可以进一步指定该网络切片实例的并发PDU会话数量在100万以上。上述“带宽”、“最大时延”和“并发PDU会话数量”均为网络切片性能指标。When ordering a network slice instance, the customer can further specify the constraints of the network slice performance indicator (the value can be a specific value or a range value). For example, if a customer chooses an eMBB type network slice, he can further specify that the bandwidth of the network slice instance is higher than 1000G; if a customer chooses a uRLLC type network slice, he can further specify that the maximum delay of the network slice instance is lower than 5 milliseconds; If the network slice of the eMTC type is selected, you can further specify that the number of concurrent PDU sessions of this network slice instance is more than 1 million. The above "Bandwidth", "Maximum Delay" and "Number of Concurrent PDU Sessions" are all network slicing performance indicators.

应理解，当需要通过多个指标描述网络切片的网络性能时，客户可以分别指定每一个网络切片性能指标对应的约束条件。为叙述方便，本申请实施例以一个指标为例进行说明。It should be understood that when the network performance of the network slice needs to be described by multiple indicators, the customer can separately specify the constraints corresponding to each network slice performance indicator. For the convenience of description, the embodiment of the present application uses an index as an example for description.

可选地，为提高客户体验，订购实体还可以提供网络切片模板供客户选择或者作为客户修改的基础。某一网络切片类型可以有多种网络切片模板，每个网络切片模板有预置的网络切片性能指标的约束条件。例如，一个网络切片模板可以是：Optionally, in order to improve customer experience, the ordering entity may also provide network slice templates for customers to select or as a basis for customer modification. A network slice type can have multiple network slice templates, and each network slice template has preset network slice performance index constraints. For example, a web slice template could be:

客户可以选择上述模板，并基于上述模板修改出匹配自身开展的业务的网络切片需求，例如修改成：Customers can select the above template and modify the network slicing requirements to match their own business based on the above template, for example, modify it to:

进一步地，客户确认该网络切片实例对应的计费规则。所述计费规则包含网络切片性能指标的统计值对应的计费方法。针对不同统计值，分别举例如下：Further, the customer confirms the charging rule corresponding to the network slice instance. The charging rules include charging methods corresponding to the statistical values of network slice performance indicators. For different statistical values, examples are as follows:

(1)统计值为达标程度的情况：例如，关于“带宽”这个网络切片性能指标，客户指定的其约束条件为“月平均带宽达到100M/s”，而其实际平均值为“88M/s”，则达标程度为88/100＝0.88，则0.88为“带宽”这个指标的达标程度；表3为示例性的达标程度与计费方法的对应关系。(1) The situation where the statistical value meets the standard: For example, regarding the network slice performance indicator "bandwidth", the constraint condition specified by the customer is "the monthly average bandwidth reaches 100M/s", while the actual average is "88M/s" ”, then the degree of compliance is 88/100=0.88, and 0.88 is the degree of compliance of the indicator “bandwidth”; Table 3 is an exemplary correspondence between the degree of compliance and the charging method.

表3table 3

除了以上形式，达标程度与计费方法的对应关系还可以是表达式、公式或者函数的形式，但其实质上也是一种映射关系或者对应关系。In addition to the above forms, the corresponding relationship between the degree of compliance and the charging method may also be in the form of an expression, a formula or a function, but it is also a mapping relationship or a corresponding relationship in essence.

(2)统计值为不达标时长的情况：例如，关于端到端时延这个网络切片性能指标，客户指定的约束条件是“全程小于5ms”，而实际出现端到端时延大于5ms(不达标)的持续时间累计达到100小时，则这100小时为不达标时长；不达标时长与计费方法的对应关系可以采用如表-4所示的方式。(2) The case where the statistical value does not meet the standard duration: For example, regarding the end-to-end delay, a network slice performance indicator, the constraint condition specified by the customer is "the whole process is less than 5ms", but the actual end-to-end delay is greater than 5ms (not The accumulative duration of meeting the standard) reaches 100 hours, then the 100 hours is the non-compliance time; the corresponding relationship between the non-compliance duration and the billing method can be as shown in Table-4.

表4Table 4

类似的，不达标时长与计费方法的对应关系也可以是表达式、公式或者函数的形式。Similarly, the corresponding relationship between the substandard duration and the billing method may also be in the form of an expression, a formula or a function.

(3)统计值为不达标累计次数的情况：例如，关于端到端时延这个网络切片性能指标，客户指定的约束条件应该是“全程小于5ms”，而实际出现端到端时延大于5ms的出现次数累计达到60次，则这60次为不达标累计次数；不达标累计次数与计费方法的对应关系可以与上述达标程度与计费方法的对应关系类似，不再赘述。(3) The cumulative number of times when the statistical value is not up to the standard: For example, regarding the end-to-end delay as a network slice performance indicator, the constraint condition specified by the customer should be "the whole process is less than 5ms", but the actual end-to-end delay is greater than 5ms The accumulative number of occurrences reaches 60 times, and the 60 times are the accumulative times of failure to meet the standard; the corresponding relationship between the cumulative number of failures to meet the standard and the charging method may be similar to the corresponding relationship between the above-mentioned degree of compliance and the charging method, and will not be repeated here.

以上计费规则仅是示意性的，本申请实施例不排除其他基于网络切片性能指标的值进行计费的计费规则。The above charging rules are only illustrative, and the embodiments of the present application do not exclude other charging rules for charging based on values of network slice performance indicators.

在客户确认计费规则、选择订购周期(即网络切片实例的使用时间范围或计费周期，通常是一个时间段)后，订购实体可以创建并存储网络切片订购信息，例如：After the customer confirms the billing rules and selects the subscription period (that is, the usage time range or billing period of the network slice instance, usually a period of time), the ordering entity can create and store network slice order information, such as:

其中“计费规则”字段的值可以是上述计费规则(例如表3的内容)经转化得到的文本字符串，该字符串可以是XML(Extensible Markup Language，可扩展标记语言)格式、JSON(JavaScript object notation,JavaScript对象表示法)格式或其他文本格式，也可以是计算机可执行脚本，还可以是上述计费规则经转化得到的二进制格式的数据。对此，本申请实施例不作限定。The value of the "charging rule" field can be a text string obtained by converting the above charging rule (for example, the content of Table 3), and the string can be in XML (Extensible Markup Language) format, JSON (Extensible Markup Language) JavaScript object notation, JavaScript object notation) format or other text formats, it may also be a computer executable script, or it may be data in a binary format obtained by converting the above charging rules. In this regard, the embodiments of the present application are not limited.

应理解，后续NSCF设备可以根据所述计费规则对相应的网络切片实例进行计费处理，为此，可以由订购实体向NSCF设备提供(如发送、文件共享等)所述计费规则，也可以由订购实体向NSCCF设备提供所述计费规则后，再由NSCCF设备向NSCF设备提供(如发送、文件共享等)所述计费规则；由于不同的网络切片实例，其计费规则可能不同，订购实体和/或NSCCF设备可以提供网络切片实例的标识与计费规则的对应关系。It should be understood that the subsequent NSCF device may perform charging processing on the corresponding network slice instance according to the charging rules. For this purpose, the subscription entity may provide (such as sending, file sharing, etc.) the charging rules to the NSCF device, and also After the subscription entity provides the charging rules to the NSCCF equipment, the NSCCF equipment provides (such as sending, file sharing, etc.) the charging rules to the NSCF equipment; due to different network slice instances, the charging rules may be different. , the ordering entity and/or the NSCCF device may provide the corresponding relationship between the identifier of the network slice instance and the charging rule.

需要说明的是，本申请实施例所述的客户，可以是拥有很多用户设备的行业客户或企业客户，如共享单车企业、出租车公司等，也可以是自然人客户，为叙述方便，本申请实施例均称之为客户。It should be noted that the customers described in the embodiments of this application may be industry customers or corporate customers with many user equipment, such as bicycle sharing companies, taxi companies, etc., or natural person customers. For the convenience of description, this application implements Examples are called customers.

步骤702：订购实体通知NSMF设备开通网络切片服务。Step 702: The ordering entity notifies the NSMF device to activate the network slicing service.

具体地，订购实体可以向NSMF设备发送开通切片服务通知，所述开通切片服务通知可以包含上述网络切片订购信息中的切片类型和约束条件，以便NSMF设备创建满足客户要求的网络切片实例。Specifically, the ordering entity may send the NSMF device a notification of activating the slice service, and the notification of activating the slicing service may include the slice type and constraints in the above-mentioned network slice order information, so that the NSMF device can create a network slice instance that meets customer requirements.

可选地，所述开通切片服务通知还可以包含客户标识，从而，NSMF设备后续可以建立所创建的网络切片实例与客户标识的对应关系。Optionally, the slicing service activation notification may further include a client identifier, so that the NSMF device can subsequently establish a corresponding relationship between the created network slice instance and the client identifier.

步骤703：NSMF设备为该客户创建网络切片实例。Step 703: The NSMF device creates a network slice instance for the client.

具体地，NSMF设备从订购实体接收上述开通网络切片通知，并根据所述通知中的网络切片类型和约束条件，创建出相应的网络切片实例，并为其分配唯一标识，即网络切片实例标识。Specifically, the NSMF device receives the above-mentioned network slice activation notification from the ordering entity, creates a corresponding network slice instance according to the network slice type and constraints in the notification, and assigns a unique identifier to it, that is, the network slice instance identifier.

可选地，NSMF设备可以将该新创建的网络切片实例分配给上述客户，即建立所述网络切片实例标识与客户标识之间的对应关系。Optionally, the NSMF device may assign the newly created network slice instance to the above-mentioned client, that is, establish a correspondence between the identifier of the network slice instance and the client identifier.

应理解，NSMF设备也可以检查网络中是否已经存在能满足客户需求的网络切片实例，如果确定已经存在，并且该网络切片实例可分配给该客户，则NSMF设备可以直接将该已经存在的网络切片实例直接分配给上述客户，从而可以省去创建新的网络切片实例的过程。It should be understood that the NSMF device can also check whether a network slice instance that can meet the customer's needs already exists in the network. If it is determined that it already exists, and the network slice instance can be assigned to the customer, the NSMF device can directly use the existing network slice. Instances are assigned directly to the aforementioned clients, thus eliminating the need to create new network slice instances.

可选地，NSMF设备可以从上述网络切片通知消息中获取上述客户标识。Optionally, the NSMF device may obtain the above-mentioned client identifier from the above-mentioned network slice notification message.

步骤704：NSMF设备向订购实体返回网络切片实例的信息。Step 704: The NSMF device returns the information of the network slice instance to the ordering entity.

具体地，NSMF设备可以向订购实体返回开通网络切片响应，所述响应中可以包括网络切片创建成功的指示信息和上述网络切片实例的信息，该信息可以包括上述网络切片实例的标识、上述网络切片实例的创建时间和上述网络切片实例的当前状态(如已创建、已激活等)等。Specifically, the NSMF device may return a network slice activation response to the ordering entity, and the response may include information indicating that the network slice is successfully created and the information of the above-mentioned network slice instance, and the information may include the identifier of the above-mentioned network slice instance, the above-mentioned network slice.

上述步骤704和步骤705可以理解为，NSMF设备通过订购实体发送网络切片实例的信息给所述NSCCF设备。可选的，NSMF设备也可以直接向NSCCF设备发送网络切片实例的信息，如：网络切片实例的标识、网络切片实例创建时间、网络切片实例的当前状态(如已创建、已激活等)等。The above steps 704 and 705 can be understood as that the NSMF device sends the information of the network slice instance to the NSCCF device through the subscription entity. Optionally, the NSMF device can also directly send the information of the network slice instance to the NSCCF device, such as the identifier of the network slice instance, the creation time of the network slice instance, the current state of the network slice instance (such as created, activated, etc.), etc.

步骤706：NSCCF设备确定针对NSI的性能指标上报操作PPRO的上报参数集RPC。Step 706: The NSCCF device determines the reporting parameter set RPC of the performance indicator reporting operation PPRO for the NSI.

具体地，NSCCF设备接收到所述网络切片订购信息和所述网络切片实例的信息后，可以根据所述网络切片订购信息和所述网络切片实例的信息，确定所述PPRO的上报参数集RPC中的上报参数，例如：可以根据所述网络切片订购信息中的切片类型和/或约束条件，确定RPC中的上报指标，根据所述网络切片订购信息中的约束条件和/或计费规则，确定RPC中的上报条件、获取方式，根据网络切片实例创建时间，确定RPC中的开始条件等。Specifically, after receiving the network slice order information and the network slice instance information, the NSCCF device may determine, according to the network slice order information and the network slice instance information, that the PPRO reports in the parameter set RPC The reporting parameters, for example: can determine the reporting index in the RPC according to the slice type and/or constraints in the network slice ordering information, and determine according to the constraints and/or charging rules in the network slice ordering information The reporting conditions and acquisition methods in the RPC, and the start conditions in the RPC are determined according to the creation time of the network slice instance.

例如，如果订购信息为：For example, if the order information is:

则可以确定RPC为：Then it can be determined that the RPC is:
