Translated fromChinese技术领域technical field
本公开涉及移动通信技术领域，特别涉及一种寻址方法及装置。The present disclosure relates to the field of mobile communication technologies, and in particular, to an addressing method and device.
背景技术Background technique
随着信息和移动通信技术的深度融合，网络资产货币化越来越受到运营商的重视。为此，第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)在标准上明确定义了业务能力开放功能(Service Capability Exposure Function，SCEF)实体，也明确定义了服务质量(Quality of Service，QoS)、计费、通信行为、用户设备(UserEquipment)状态、网络状态、数据等网络能力开放场景。业务能力开放功能是将运营商网络的能力开放给应用或终端，为应用或终端提供差异化、精细化的产品和服务的能力，同时也是保障运营商网络安全的有效屏障。业务能力开放功能面向互联网服务提供商/内容提供商(Service Provider/Content Provider，SP/CP)，SP/CP中提供商的用户标识和运营商的用户标识完全独立，通常来说，提供商在请求QoS时，需要基于互联网向用户提供各种应用服务(Over The Top，OTT消息)向SCEF申请。With the deep integration of information and mobile communication technologies, the monetization of network assets has attracted more and more attention from operators. To this end, the 3rd Generation Partnership Project (3GPP) clearly defines the Service Capability Exposure Function (SCEF) entity in the standard, and also clearly defines the Quality of Service (QoS) , billing, communication behavior, user equipment (User Equipment) status, network status, data and other network capability opening scenarios. The business capability opening function is to open the capabilities of the operator's network to applications or terminals, and to provide differentiated and refined products and services for applications or terminals. It is also an effective barrier to ensure the security of the operator's network. The service capability opening function is oriented to the Internet Service Provider/Content Provider (SP/CP). The user ID of the provider in the SP/CP and the user ID of the operator are completely independent. When requesting QoS, it is necessary to provide various application services (Over The Top, OTT message) to the user based on the Internet and apply to SCEF.
在向SCEF申请诸如QoS能力的PCRF网络能力时，OTT消息需要向SCEF发送携带OTT消息用户的私网网络之间互连的协议(Internet Protocol，IP)以及公网IP的QoS能力申请消息；当SCEF接收到QoS能力申请消息时，向AAA协议标准路由代理(Diameter RoutingAgent，DRA)发送携带用户私网IP和公网IP的QoS能力申请消息，DRA根据接收到的私网IP和公网IP来确定用户的PCEF设备与PCRF设备之间(Gx)接口会话信息表，并绑定Gx接口会话信息表，在Gx接口会话信息表中寻址，获取用户所在的PCRF网元的身份(Identity，ID)信息，并由DRA向确定的PCRF网元转发SCEF的QoS能力申请消息。When applying to SCEF for PCRF network capabilities such as QoS capabilities, the OTT message needs to send to SCEF the protocol (Internet Protocol, IP) that carries the interconnection between the private network networks of the OTT message user and the QoS capability application message of the public network IP; when When SCEF receives the QoS capability application message, it sends the QoS capability request message carrying the user's private network IP and public network IP to the AAA protocol standard routing agent (Diameter RoutingAgent, DRA). Determine the (Gx) interface session information table between the user's PCEF device and the PCRF device, bind the Gx interface session information table, address in the Gx interface session information table, and obtain the identity (Identity, ID) of the PCRF network element where the user is located. ) information, and the DRA forwards the SCEF QoS capability application message to the determined PCRF network element.
在实现本公开的过程中，发明人发现现有技术至少存在以下问题：In the process of realizing the present disclosure, the inventor found that the prior art has at least the following problems:
由于DRA需要根据私网IP和公网IP来绑定Gx接口会话信息表，因此，DRA需要开启Gx接口会话绑定功能，并且需要存储全网用户的Gx接口会话信息表，但DRA的存储容量有限，这样，便需要对DRA进行扩容，导致部署的成本较高。Since the DRA needs to bind the Gx interface session information table according to the private network IP and public network IP, the DRA needs to enable the Gx interface session binding function, and needs to store the Gx interface session information table of users on the entire network, but the storage capacity of the DRA is limited. In this way, the DRA needs to be expanded, resulting in higher deployment costs.

为了避免对DRA造成较大的存储压力，本公开将用户标识和PCRF标识直接存储在通信系统中的网络设备上。通信系统中可以增加用于存储用户标识和PCRF标识的网络设备，也可将用户标识和PCRF标识存储在通信系统中的已有网元上，例如，可以存储在SCEF、认证，授权和计费(Authentication，Authorization and Accounting，AAA)网元、PCRF、PGW、DRA等，本公开对用户标识和PCRF标识的存储位置不进行具体限定。In order to avoid greater storage pressure on the DRA, the present disclosure directly stores the user ID and the PCRF ID on the network device in the communication system. A network device for storing user IDs and PCRF IDs can be added to the communication system, and user IDs and PCRF IDs can also be stored on existing network elements in the communication system. For example, they can be stored in SCEF, authentication, authorization, and billing (Authentication, Authorization and Accounting, AAA) network element, PCRF, PGW, DRA, etc. The present disclosure does not specifically limit the storage locations of the user identifier and the PCRF identifier.
当用户标识和PCRF标识存储在诸如SCEF或AAA网元上时，由于SCEF或AAA网元本身就具有寻址以及进行Qos能力请求的功能，因此，可以直接基于设备所存储的用户标识和PCRF标识来进行后续的寻址和能力请求过程，可以将这类设备称为业务能力开放功能实体。当用户标识和PCRF标识存储在通信系统中除SCEF或AAA网元以外的其他网络设备上时，例如PCRF、PGW或DRA等网络设备，这些网络设备可能不具有寻址以及进行Qos能力请求的功能，因此，可将这类网络设备看做存储实体，这样，SCEF或AAA网元在进行寻址时如果需要获取PCRF标识，则可以通过与这些存储实体进行交互，以获取用户标识对应的PCRF标识，从而通过寻址来确定PCRF，进而为UE进行Qos能力请求。下面，基于上述两类不同方式的部署对寻址过程进行描述：When the user ID and PCRF ID are stored on the network element such as SCEF or AAA, because the SCEF or AAA network element itself has the functions of addressing and requesting QoS capabilities, it can be directly based on the user ID and PCRF ID stored in the device. To carry out subsequent addressing and capability request processes, such devices can be called service capability openness functional entities. When the user ID and PCRF ID are stored on other network devices other than SCEF or AAA network elements in the communication system, such as PCRF, PGW or DRA and other network devices, these network devices may not have the function of addressing and requesting QoS capabilities Therefore, such network devices can be regarded as storage entities. In this way, if the SCEF or AAA network element needs to obtain the PCRF identifier during addressing, it can interact with these storage entities to obtain the PCRF identifier corresponding to the user identifier. , so as to determine the PCRF through addressing, and then perform a QoS capability request for the UE. Below, the addressing process is described based on the deployment of the above two different modes:
首先，介绍用户标识和PCRF标识存储在SCEF或AAA网元上时的寻址过程，其具体步骤可以参照图3A中的过程，图3A是根据一示例性实施例示出的一种寻址方法的流程图。如图3A所示，该方法包括以下步骤。First, the addressing process when the user identity and PCRF identity are stored on the SCEF or AAA network element is introduced. For the specific steps, please refer to the process in FIG. 3A , which shows an addressing method according to an exemplary embodiment. flow chart. As shown in Figure 3A, the method includes the following steps.
在步骤301中，UE建立与PGW之间的IP CAN会话，PGW与PCRF网元交互CCR和CCA，完成UE在通信系统中的注册。In step 301, the UE establishes an IP CAN session with the PGW, and the PGW exchanges CCR and CCA with the PCRF network element to complete the registration of the UE in the communication system.
在本公开实施例中，当UE请求在通信系统中进行注册时，需要建立与PGW之间的IPCAN会话，并基于IP CAN会话将注册信息发送至PGW；当PGW接收到UE的注册信息时，在至少一个PCRF网元中选取可注册的PCRF网元，并向PCRF网元发送携带注册信息的信用控制请求(Credit Control Request，CCR)，以使PCRF网元在接收到CCR后，对UE进行注册，并在注册成功后，向PGW返回携带PCRF标识的信用控制应答(Credit Control Answer，CCA)，以便PGW将PCRF标识返回至UE，完成UE在通信系统中的注册。In the embodiment of the present disclosure, when the UE requests to register in the communication system, it needs to establish an IPCAN session with the PGW, and send the registration information to the PGW based on the IP CAN session; when the PGW receives the UE's registration information, Select a registrable PCRF network element from at least one PCRF network element, and send a credit control request (Credit Control Request, CCR) carrying registration information to the PCRF network element, so that the PCRF network element, after receiving the CCR, performs After the registration is successful, a Credit Control Answer (CCA) carrying the PCRF identifier is returned to the PGW, so that the PGW returns the PCRF identifier to the UE to complete the registration of the UE in the communication system.
在步骤302中，PGW向SCEF发送用户标识和PCRF标识，PCRF标识用于标识用户所在的PCRF网元。In step 302, the PGW sends the user identifier and the PCRF identifier to the SCEF, and the PCRF identifier is used to identify the PCRF network element where the user is located.
其中，用户标识为UE在通信系统中注册时，通信系统为UE生成的唯一通用标识，可以由固定网号码(Mobile Subscriber International ISDN/PSTN Number，MSISDN)、国际用户识别码(International Mobile Subscriber Identification Number，IMSI)、用户的公网IP和/或私网IP、接入点(Access Point Name，APN)以及用户临时标识中的一种或多种组成。PCRF标识用于唯一标识一个PCRF，PCRF标识一般为PCRF主机名信息，也可以是其他可以唯一标识PCRF网元信息，例如IP或设备编号等。Wherein, the user identifier is the unique universal identifier generated by the communication system for the UE when the UE registers in the communication system, which can be determined by a fixed network number (Mobile Subscriber International ISDN/PSTN Number, MSISDN), an International Mobile Subscriber Identification Number (International Mobile Subscriber Identification Number) , IMSI), one or more of the user's public network IP and/or private network IP, an access point (Access Point Name, APN), and a user temporary identity. The PCRF identifier is used to uniquely identify a PCRF, and the PCRF identifier is generally PCRF host name information, and may also be other information that can uniquely identify the PCRF network element, such as IP or device number.
由于UE在通信系统中进行注册时，会注册至通信系统中的某一PCRF网元上，因此，当UE在通信系统中注册成功后，PGW便可获取UE所在的PCRF网元的PCRF标识。为了使SCEF获取到用户标识和PCRF标识，并简化SCEF请求用户标识和PCRF标识的流程，PGW可主动将用户标识和PCRF标识上传至SCEF，以使SCEF将用户标识和PCRF标识对应进行存储。Since the UE registers in the communication system, it will register with a PCRF network element in the communication system. Therefore, after the UE is successfully registered in the communication system, the PGW can obtain the PCRF identifier of the PCRF network element where the UE is located. In order for SCEF to obtain the user ID and PCRF ID, and to simplify the process of SCEF requesting the user ID and PCRF ID, the PGW can actively upload the user ID and PCRF ID to SCEF, so that SCEF stores the user ID and PCRF ID correspondingly.
PGW在将用户标识和PCRF标识发送至SCEF时，可以基于当前通信系统中已有接口发送，也可在通信系统中新建一个或多个新增接口，并基于新增接口将用户标识和PCRF标识发送至SCEF。其中，已有接口可为开源异步编程(Reactive Extensions，Rx)接口、API接口或认证服务(Radius)接口。若基于Radius接口发送用户标识和PCRF标识，则PGW在将用户标识和PCRF标识发送至SCEF之前，需要基于Radius接口生成消息，并在消息中添加需要发送的用户标识和PCRF标识，生成验证消息，并将验证消息发送至SCEF，由SCEF在验证消息中提取用户标识和PCRF标识，将用户标识和PCRF标识对应进行存储，以便在后续进行寻址时，SCEF可以直接确定与用户标识对应的PCRF标识。其中，PGW基于Radius接口生成消息可为接入请求(Access-Request)消息或统计请求(Accounting-Request)消息，本公开对PGW基于Radius接口生成的消息不进行具体限定。When the PGW sends the user ID and the PCRF ID to the SCEF, it can send it based on the existing interface in the current communication system, or it can create one or more new interfaces in the communication system, and based on the newly added interface, the user ID and PCRF ID can be sent. Sent to SCEF. The existing interface may be an open source asynchronous programming (Reactive Extensions, Rx) interface, an API interface or an authentication service (Radius) interface. If the user ID and PCRF ID are sent based on the Radius interface, before sending the user ID and PCRF ID to the SCEF, the PGW needs to generate a message based on the Radius interface, and add the user ID and PCRF ID to be sent in the message to generate a verification message. Send the verification message to the SCEF, and the SCEF extracts the user ID and the PCRF ID in the verification message, and stores the user ID and the PCRF ID correspondingly, so that when the subsequent addressing is performed, the SCEF can directly determine the PCRF ID corresponding to the user ID. . Wherein, the message generated by the PGW based on the Radius interface may be an access request (Access-Request) message or an accounting request (Accounting-Request) message, and the present disclosure does not specifically limit the message generated by the PGW based on the Radius interface.
在本申请实施例中，仅以发送用户标识和PCRF标识的网络设备为PGW为例进行说明，而在实际场景中，还可以由分组网关实体来进行发送，这种实时上报用户标识以及用户所在的PCRF标识的方式，可以避免由于上报不及时而造成的处理时延和处理错误。In the embodiment of this application, only the network device that sends the user ID and PCRF ID is the PGW as an example for description, but in an actual scenario, the packet gateway entity can also send it. The PCRF identification method can avoid processing delay and processing errors caused by untimely reporting.
在步骤303中，当SCEF接收到用户标识和PCRF标识时，将用户标识与PCRF标识对应存储。In step 303, when the SCEF receives the user identification and the PCRF identification, the user identification and the PCRF identification are stored correspondingly.
在本公开实施例中，SCEF在接收到PGW发送的用户标识和PCRF标识后，由于SCEF可以存储用户标识和PCRF标识，因此，SCEF便直接将用户标识和PCRF标识对应进行存储，以便在后续进行寻址时，SCEF可以直接确定与用户标识对应的PCRF标识。In the embodiment of the present disclosure, after the SCEF receives the user identifier and the PCRF identifier sent by the PGW, since the SCEF can store the user identifier and the PCRF identifier, the SCEF directly stores the user identifier and the PCRF identifier correspondingly, so that the subsequent When addressing, the SCEF can directly determine the PCRF identity corresponding to the user identity.
其中，SCEF在接收用户标识和PCRF标识时，可基于上述步骤302中提及的已有接口或新增接口接收，本公开对SCEF接收用户标识和PCRF标识的方式不进行具体限定。Wherein, when the SCEF receives the user identifier and the PCRF identifier, it can be received based on the existing interface or the newly added interface mentioned in the above step 302, and the present disclosure does not specifically limit the manner in which the SCEF receives the user identifier and the PCRF identifier.
需要说明的是，上述步骤302和步骤303中所示的过程为PGW主动将用户标识与PCRF标识上传至SCEF，由SCEF进行存储的过程，而在实际应用的过程中，参见图3B，SCEF还可以采取下述两种方式在PGW中获取用户标识和PCRF标识。It should be noted that the process shown in the above steps 302 and 303 is the process in which the PGW actively uploads the user ID and the PCRF ID to the SCEF, and the SCEF stores them. In the actual application process, referring to FIG. 3B , the SCEF also The following two ways may be adopted to obtain the user identity and the PCRF identity in the PGW.
方式一、SCEF向PGW发送携带用户标识的标识获取请求，并接收PGW返回的用户标识对应的PCRF标识。Manner 1: The SCEF sends an identification acquisition request carrying the user identification to the PGW, and receives the PCRF identification corresponding to the user identification returned by the PGW.
当UE完成在通信系统中的注册后，由于通信系统中的全部网络设备均可获取到UE的用户标识，这样，SCEF可以基于用户标识向PGW请求与用户标识对应的PCRF标识。当PGW接收到SCEF发送的用户标识后，确定与用户标识对应的PCRF标识，并将PCRF标识返回至SCEF，由SCEF将用户标识和PCRF标识对应进行存储，以便在后续进行寻址时，SCEF可以直接确定与用户标识对应的PCRF标识。由于PGW仅在接收到SCEF的标识获取请求时，才将PCRF标识发送至SCEF，因此，可以避免由于通信系统中注册的UE过多，导致SCEF可能接收到的并行数据过多，造成SCEF的存储压力过大。After the UE completes the registration in the communication system, since all network devices in the communication system can obtain the UE's user identity, the SCEF can request the PGW for the PCRF identity corresponding to the user identity based on the user identity. After the PGW receives the user ID sent by SCEF, it determines the PCRF ID corresponding to the user ID, and returns the PCRF ID to SCEF, where SCEF stores the user ID and PCRF ID correspondingly, so that SCEF can The PCRF identifier corresponding to the user identifier is directly determined. Since the PGW only sends the PCRF identifier to the SCEF when it receives the identifier acquisition request of the SCEF, it can avoid that the SCEF may receive too much parallel data due to too many UEs registered in the communication system, resulting in the storage of the SCEF. Too much pressure.
其中，PGW在将用户标识和PCRF标识发送至SCEF时，可以基于上述步骤302中的方式进行发送，此处不再进行赘述。Wherein, when the PGW sends the user identifier and the PCRF identifier to the SCEF, the sending may be based on the manner in the foregoing step 302, which will not be repeated here.
方式二、若PGW配置有超文本传输协议(HyperText Transfer Protocol，HTTP)头增强功能，则SCEF获取PGW发送的用户标识和HTTP，在HTTP的头信息中获取PCRF标识。Manner 2: If the PGW is configured with the HyperText Transfer Protocol (HyperText Transfer Protocol, HTTP) header enhancement function, the SCEF obtains the user ID and HTTP sent by the PGW, and obtains the PCRF ID from the HTTP header information.
在本公开实施例中，若PGW配置有HTTP头增强功能，则PGW可以修改HTTP的头信息，在HTTP的头信息中增加相应信息，这样，当UE完成在通信系统中的注册后，UE便可直接访问SCEF中的网络服务(Web Server)，这样，PGW便可检测到UE的访问行为，并获取UE在访问WebServer时的HTTP，将PCRF标识添加至HTTP的头信息中，将HTTP和用户标识发送至SCEF，由SCEF在HTTP中提取PCRF标识，将用户标识和PCRF标识对应存储，以便在后续进行寻址时，SCEF可以直接确定与用户标识对应的PCRF标识。In the embodiment of the present disclosure, if the PGW is configured with the HTTP header enhancement function, the PGW can modify the HTTP header information and add corresponding information to the HTTP header information. In this way, after the UE completes the registration in the communication system, the UE can It can directly access the network service (Web Server) in SCEF, so that the PGW can detect the access behavior of the UE, and obtain the HTTP when the UE accesses the WebServer, add the PCRF identifier to the HTTP header information, and connect the HTTP and user The identifier is sent to the SCEF, and the SCEF extracts the PCRF identifier in HTTP, and stores the user identifier and the PCRF identifier correspondingly, so that in subsequent addressing, the SCEF can directly determine the PCRF identifier corresponding to the user identifier.
由于PGW可以直接修改HTTP的头信息，在HTTP的头信息中添加PCRF标识，因此，无需再生成携带PCRF标识的其他请求，简化了将PCRF标识传输至SCEF的流程，避免通信系统中的请求过多导致通信系统的负载过大。Since the PGW can directly modify the HTTP header information and add the PCRF identifier to the HTTP header information, there is no need to generate other requests carrying the PCRF identifier, which simplifies the process of transmitting the PCRF identifier to the SCEF and avoids excessive requests in the communication system. Mostly lead to the overload of the communication system.
在步骤304中，SCEF接收SP/CP的申请能力请求，申请能力请求携带用户标识。In step 304, the SCEF receives the application capability request from the SP/CP, and the application capability request carries the user identifier.
在本公开实施例中，当SP/CP需要获取PCRF网元的服务质量能力时，可以向SCEF发送携带用户标识的申请能力请求，以便SCEF确定与用户标识对应的PCRF标识，基于PCRF标识进行寻址，向PCRF标识对应的PCRF网元进行服务质量能力请求。需要说明的是，该申请能力请求可为OTT消息，该OTT消息可由SP或CP上的OTT服务发送，本公开实施例对此申请能力请求的类型以及发送方式不进行具体限定。In the embodiment of the present disclosure, when the SP/CP needs to obtain the service quality capability of the PCRF network element, it can send a request for capability application carrying the user ID to the SCEF, so that the SCEF determines the PCRF ID corresponding to the user ID, and searches for the PCRF ID based on the PCRF ID. address, and request the QoS capability to the PCRF network element corresponding to the PCRF identifier. It should be noted that the application capability request may be an OTT message, and the OTT message may be sent by the OTT service on the SP or CP. The embodiment of the present disclosure does not specifically limit the type and transmission method of the application capability request.
在步骤305中，SCEF基于申请能力请求携带的用户标识，在已存储的用户标识与PCRF标识中，确定PCRF标识。In step 305, the SCEF determines the PCRF identifier from the stored user identifier and PCRF identifier based on the user identifier carried in the application capability request.
在本公开实施例中，SCEF在确定用户标识对应的PCRF标识时，可以直接在申请能力请求中提取用户标识，并在已存储的用户标识与PCRF标识中查找用户标识对应的PCRF标识。In the embodiment of the present disclosure, when the SCEF determines the PCRF identifier corresponding to the user identifier, it can directly extract the user identifier from the application capability request, and search the stored user identifier and PCRF identifier for the PCRF identifier corresponding to the user identifier.
在步骤306中，SCEF基于PCRF标识进行寻址，得到与PCRF标识对应的PCRF网元，向PCRF标识对应的PCRF网元进行服务质量能力请求。In step 306, the SCEF performs addressing based on the PCRF identifier, obtains the PCRF network element corresponding to the PCRF identifier, and makes a service quality capability request to the PCRF network element corresponding to the PCRF identifier.
在本公开实施例中，当SCEF确定用户标识对应的PCRF标识后，便可基于PCRF标识进行寻址，确定与PCRF标识对应的PCRF网元，并向PCRF网元请求服务质量能力。在获取到服务质量能力的能力参数后，SCEF可将服务质量能力的能力参数返回给SP/CP，以使SP/CP基于能力参数为用户提供服务。In the embodiment of the present disclosure, after the SCEF determines the PCRF identifier corresponding to the user identifier, it can address based on the PCRF identifier, determine the PCRF network element corresponding to the PCRF identifier, and request the QoS capability from the PCRF network element. After acquiring the capability parameter of the QoS capability, the SCEF may return the capability parameter of the QoS capability to the SP/CP, so that the SP/CP provides a service for the user based on the capability parameter.
本公开实施例所述的方法，SCEF通过获取用户的用户标识和规则功能PCRF标识，将用户标识与PCRF标识对应存储，使得在接收到携带用户标识的申请能力请求时，可以直接从已存储的用户标识与PCRF标识中，确定与用户标识对应的PCRF标识，基于PCRF标识进行寻址，得到与PCRF标识对应的PCRF网元，向PCRF标识对应的PCRF网元进行服务质量能力请求，无需为用户建立Gx接口会话信息表，避免了对DRA的存储容量进行扩容，降低了通信系统的部署成本。In the method described in the embodiments of the present disclosure, SCEF obtains the user ID of the user and the PCRF ID of the rule function, and stores the user ID and the PCRF ID correspondingly, so that when receiving the application capability request carrying the user ID, the user ID can be directly retrieved from the stored user ID. Among the user identification and the PCRF identification, determine the PCRF identification corresponding to the user identification, perform addressing based on the PCRF identification, obtain the PCRF network element corresponding to the PCRF identification, and request the service quality capability to the PCRF network element corresponding to the PCRF identification, without requiring the user The establishment of the Gx interface session information table avoids the expansion of the storage capacity of the DRA and reduces the deployment cost of the communication system.
由于用户标识和PCRF标识还可存储在PCRF、PGW或DRA等网络设备，下面，以用户标识和PCRF标识存储在PCRF上为例介绍寻址过程，其具体步骤可以参照图4A中的过程。图4A是根据一示例性实施例二示出的一种寻址方法的流程图。如图4A所示，该方法包括以下步骤。Since the user ID and PCRF ID can also be stored in network devices such as PCRF, PGW, or DRA, the addressing process is described below by taking the user ID and PCRF ID stored on the PCRF as an example, and the specific steps can refer to the process in FIG. 4A . FIG. 4A is a flowchart of an addressing method according to an
在步骤401中，UE建立与PGW之间的IP CAN会话，PGW与PCRF网元交互CCR和CCA，完成UE在通信系统中的注册。In step 401, the UE establishes an IP CAN session with the PGW, and the PGW exchanges CCR and CCA with the PCRF network element to complete the registration of the UE in the communication system.
在本公开实施例中，UE在通信系统中注册的过程与上述步骤301中所示的过程一致，此处不再进行赘述。In the embodiment of the present disclosure, the process of the UE registering in the communication system is the same as the process shown in the foregoing step 301, which will not be repeated here.
在步骤402中，PGW向PCRF发送用户标识和PCRF标识。In step 402, the PGW sends the user identity and the PCRF identity to the PCRF.
在本公开实施例中，由于UE在通信系统中进行注册时，会注册至通信系统中的某一PCRF网元上，因此，当UE在通信系统中注册成功后，PGW便可获取UE所在的PCRF网元的PCRF标识。为了使PCRF获取用户标识和PCRF标识，并简化PCRF获取用户标识和PCRF标识的流程，PGW可主动将用户标识和PCRF标识上传至PCRF，以使PCRF将用户标识和PCRF标识对应进行存储。In the embodiment of the present disclosure, when the UE registers in the communication system, it will register with a certain PCRF network element in the communication system. Therefore, after the UE is successfully registered in the communication system, the PGW can obtain the location where the UE is located. PCRF identifier of the PCRF network element. In order to enable the PCRF to obtain the user ID and the PCRF ID, and to simplify the process for the PCRF to obtain the user ID and the PCRF ID, the PGW can actively upload the user ID and the PCRF ID to the PCRF, so that the PCRF stores the user ID and the PCRF ID correspondingly.
PGW在将用户标识和PCRF标识发送至PCRF时，可以基于当前通信系统中已有接口发送，也可在通信系统中新建一个或多个新增接口。其中，PGW基于接口将用户标识和PCRF标识发送至PCRF的过程与上述步骤302中的PGW基于接口将用户标识和PCRF标识发送至SCEF的过程一致，此处不再进行赘述。When the PGW sends the user identifier and the PCRF identifier to the PCRF, it may send based on an existing interface in the current communication system, or may create one or more newly-added interfaces in the communication system. The process of the PGW sending the user identifier and the PCRF identifier to the PCRF based on the interface is the same as the process of the PGW sending the user identifier and the PCRF identifier to the SCEF based on the interface in step 302, and will not be repeated here.
在步骤403中，PCRF接收用户标识和PCRF标识，将用户标识与PCRF标识对应存储。In step 403, the PCRF receives the user identification and the PCRF identification, and stores the user identification and the PCRF identification correspondingly.
在本公开实施例中，PCRF在接收到PGW发送的用户标识和PCRF标识后，由于PCRF可以存储用户标识和PCRF标识，因此，PCRF直接将用户标识和PCRF标识对应进行存储，以便在后续进行寻址时，PCRF可以直接确定与用户标识对应的PCRF标识。In the embodiment of the present disclosure, after the PCRF receives the user identifier and the PCRF identifier sent by the PGW, since the PCRF can store the user identifier and the PCRF identifier, the PCRF directly stores the user identifier and the PCRF identifier correspondingly, so as to search for the user identifier and the PCRF identifier later. When the address is used, the PCRF can directly determine the PCRF identity corresponding to the user identity.
其中，PCRF在接收用户标识和PCRF标识时，可基于上述步骤302中提及的已有接口或新增接口接收，本公开对PCRF接收用户标识和PCRF标识的方式不进行具体限定。Wherein, when the PCRF receives the user identifier and the PCRF identifier, it can be received based on the existing interface or the newly added interface mentioned in the above step 302, and the present disclosure does not specifically limit the manner in which the PCRF receives the user identifier and the PCRF identifier.

方式二、若PGW配置有HTTP头增强功能，则PCRF获取PGW发送的用户标识和HTTP，在HTTP的头信息中获取PCRF标识。Manner 2: If the PGW is configured with the HTTP header enhancement function, the PCRF obtains the user ID and the HTTP sent by the PGW, and obtains the PCRF ID in the HTTP header information.
在本公开实施例中，PGW向PCRF发送用户标识和HTTP以及PCRF获取PCRF标识的过程与上述实施例一中所示的方式二的过程一致，此处不再进行赘述。In the embodiment of the present disclosure, the process that the PGW sends the user identity and the HTTP to the PCRF and the process that the PCRF obtains the PCRF identity is the same as the process of the second method shown in the first embodiment, and will not be repeated here.
在步骤404中，当SCEF接收到SP/CP发送的申请能力请求时，向PCRF发送携带用户标识的网元标识请求。In step 404, when the SCEF receives the capability application request sent by the SP/CP, it sends a network element identification request carrying the user identification to the PCRF.

When the SCEF receives the application capability request sent by the SP/CP, it can extract the user identifier from the application capability request, and generate a network element identifier request based on the user identifier. The PCRF sends a network element identification request, so as to obtain the PCRF identification corresponding to the user identification in the PCRF.
在步骤405中，PCRF接收SCEF发送的网元标识请求，从已存储的用户标识与PCRF标识中，确定与用户标识对应的PCRF标识。In step 405, the PCRF receives the network element identification request sent by the SCEF, and determines the PCRF identification corresponding to the user identification from the stored user identification and PCRF identification.
