一种通信方法及装置A communication method and device

技术领域technical field

本发明涉及通信技术领域，尤其涉及一种通信方法及装置。The present invention relates to the technical field of communication, in particular to a communication method and device.

背景技术Background technique

移动通信网络在支持传统的移动宽带(Mobile Broadband，MBB)场景的同时，还需要支持新的场景。新的场景对网络有不同的需求，例如对计费，策略控制，安全和移动性等功能有不同的需求。移动宽带场景可能要求与应用相关的计费和策略控制，然而其他场景可能要求更简单的计费或策略。While supporting traditional mobile broadband (Mobile Broadband, MBB) scenarios, a mobile communication network also needs to support new scenarios. New scenarios have different requirements on the network, such as functions such as billing, policy control, security, and mobility. Mobile broadband scenarios may require application-dependent charging and policy control, while other scenarios may require simpler charging or policy.

为了更好地支持不同的场景，需要隔离不同场景的业务。例如，大量的电子传感器故障不能影响MBB用户。凭借网络切片技术，单一物理网络可以划分成多个虚拟网络，从而为不同用户群使用的不同业务提供最佳支持。网络切片(Slice)的定义如下：网络切片由三层组成：业务实例层，网络切片实例层和资源层。如图1所示，对上述三层的介绍如下：(1)、业务实例层代表的是支持的业务(终端用户业务或商业业务)。每个业务实例代表一个业务。一般而言，业务可由网络运营商或第三方提供。因此，业务实例可代表运营商业务或第三方提供的业务。(2)、网络切片实例向业务实例提供其所需的网络特征。网络运营商提供的多个业务实例可共享一个网络切片实例。网络切片实例可能包括0个、1个或多个子网实例，这些子网实例可能被其他的网络切片实例共享。子网实例由一组网络功能组成，这些网络功能运行于物理/逻辑资源之上。(3)、资源层包括物理资源和逻辑资源。其中物理资源是计算机，存储和传输资源(包括无线接入)的集合。逻辑资源是为网络功能专门划分的物理资源，或由一组网络功能共享的物理资源。每个网络切片包括逻辑网络功能的集合，该集合支持特定场景的通信业务需求。逻辑功能可以是位置管理功能，切换控制功能，会话管理功能等。根据网络切片提供的业务不同，网络切片内包括的具体逻辑功能不同，例如支持移动宽带业务的切片需要支持上述三种功能，而支持物联网业务的切片不需要支持位置管理功能和切换控制功能。In order to better support different scenarios, services in different scenarios need to be isolated. For example, a large number of electronic sensor failures cannot affect MBB users. With network slicing technology, a single physical network can be divided into multiple virtual networks to provide optimal support for different services used by different user groups. The definition of network slicing (Slice) is as follows: network slicing consists of three layers: business instance layer, network slice instance layer and resource layer. As shown in Figure 1, the introduction to the above three layers is as follows: (1) The service instance layer represents the supported services (end user services or commercial services). Each business instance represents a business. In general, services can be provided by network operators or third parties. Therefore, a service instance may represent an operator service or a service provided by a third party. (2) The network slice instance provides the required network features to the service instance. Multiple service instances provided by network operators can share one network slice instance. A network slice instance may include 0, 1 or more subnet instances, and these subnet instances may be shared by other network slice instances. A subnet instance consists of a set of network functions that run on top of physical/logical resources. (3) The resource layer includes physical resources and logical resources. Among them, physical resource is a collection of computer, storage and transmission resources (including wireless access). Logical resources are physical resources that are dedicated to network functions or shared by a group of network functions. Each network slice includes a collection of logical network functions that support the communication service requirements of a specific scenario. Logical functions may be location management functions, handover control functions, session management functions, etc. According to the different services provided by the network slice, the specific logical functions included in the network slice are different. For example, the slice supporting the mobile broadband service needs to support the above three functions, while the slice supporting the Internet of Things service does not need to support the location management function and handover control function.

参见图2，图中示出了现有技术中的寻呼过程，具体步骤如下：Referring to Figure 2, the paging process in the prior art is shown in the figure, and the specific steps are as follows:

步骤201、SGW(服务网关)接收到来自PDN GW(PDN网关)的下行数据(Downlink Data)，但是SGW没有UE(终端)的下行用户面连接(即SGW的上下文数据中没有下行用户面TEID)，SGW缓存下行数据包；Step 201, SGW (Serving Gateway) receives downlink data (Downlink Data) from PDN GW (PDN Gateway), but SGW does not have UE (terminal) downlink user plane connection (that is, there is no downlink user plane TEID in the context data of SGW) , the SGW buffers the downlink data packet;

步骤202a～202b、SGW向MME(移动性管理实体)发送下行链路数据通知消息(Downlink Data Notification)，MME向SGW返回下行数据第四确认消息(Downlink Data Notification Ack)；Steps 202a-202b, SGW sends a downlink data notification message (Downlink Data Notification) to MME (Mobility Management Entity), and MME returns a fourth downlink data confirmation message (Downlink Data Notification Ack) to SGW;

步骤203、MME向UE注册的跟踪区内的每个eNB(演进型基站)发送寻呼消息(Paging)；Step 203, MME sends a paging message (Paging) to each eNB (evolved base station) in the tracking area registered by the UE;

步骤204、eNB寻呼UE(Paging)；Step 204, eNB paging UE (Paging);

步骤205、UE接收到寻呼提示，发起业务请求过程(Service RequestProcedure)。Step 205, the UE receives the paging prompt, and initiates a service request procedure (Service Request Procedure).

业务请求过程结束之后，数据连接建立成功，SGW将缓存的下行数据发送给UE(Downlink Data E-UTRN)。After the service request process ends, the data connection is successfully established, and the SGW sends the buffered downlink data to the UE (Downlink Data E-UTRN).

参见图3，图中示出了现有技术中的业务请求过程，具体步骤如下：Referring to Fig. 3, the figure shows the service request process in the prior art, and the specific steps are as follows:

步骤301、UE向MME发送业务请求消息(Service Request)，该消息被封装在RRC(Radio Resource Control,无线资源控制)消息中，并发送给eNB；Step 301, the UE sends a service request message (Service Request) to the MME, the message is encapsulated in an RRC (Radio Resource Control, radio resource control) message, and sent to the eNB;

步骤302、eNB将业务请求消息封装在初始UE消息中，然后发送给MME。Step 302, the eNB encapsulates the service request message in the initial UE message, and then sends it to the MME.

步骤303、MME可能会发起认证和安全的过程(Authentication/Security)；Step 303, the MME may initiate an authentication and security process (Authentication/Security);

步骤304、MME向eNB发送初始上下文建立请求消息；Step 304, the MME sends an initial context establishment request message to the eNB;

步骤305、eNB执行无线承载建立过程(Initial Context Setup Request)；Step 305, the eNB executes the radio bearer establishment process (Initial Context Setup Request);

步骤306、UE可将上行数据(Uplink Data)通过eNB发送给SGW；Step 306, the UE can send the uplink data (Uplink Data) to the SGW through the eNB;

步骤307、eNB向MME发送初始上下文建立完成消息(Initial Context SetupComplete)；Step 307, the eNB sends an initial context setup complete message (Initial Context SetupComplete) to the MME;

步骤308、MME向SGW发送修改承载请求消息(Modify Bearer Request)；Step 308, the MME sends a modify bearer request message (Modify Bearer Request) to the SGW;

步骤309、如果无线接入类型、UE位置或UE所在时区发生变化，SGW向PGW发送修改承载请求消息(Modify Bearer Request)，将上述改变的信息通知给PGW；Step 309: If the radio access type, UE location or time zone where the UE is located changes, the SGW sends a Modify Bearer Request message to the PGW, and notifies the PGW of the above-mentioned changed information;

步骤310、如果部署了动态PCC，PGW与PCRF交互获得PCC规则(PCEFInitiated IP-CAN Session Modification)；Step 310, if dynamic PCC is deployed, PGW interacts with PCRF to obtain PCC rules (PCEFInitiated IP-CAN Session Modification);

步骤311、PGW向SGW发送修改承载回复消息(Modify Bearer Response)；Step 311, the PGW sends a modify bearer response message (Modify Bearer Response) to the SGW;

步骤312、SGW向MME返回修改承载回复消息(Modify Bearer Response)。Step 312, the SGW returns a modify bearer response message (Modify Bearer Response) to the MME.

根据现有方法，当网络接收到空闲态UE的数据包时，网络通过寻呼操作，触发UE进入连接态，然后将数据发送给UE。由于每个网络切片为终端提供的业务不同，因此每个网络切片相当于一个独立的网络。当终端连接到多个网络切片时，如果终端处于空闲态，每个网络切片接收到该终端的下行数据时，将分别执行寻呼操作，会导致大量的空口资源的开销。According to the existing method, when the network receives the data packet of the UE in the idle state, the network triggers the UE to enter the connected state through a paging operation, and then sends the data to the UE. Since each network slice provides different services for terminals, each network slice is equivalent to an independent network. When a terminal is connected to multiple network slices, if the terminal is in an idle state, each network slice will perform a paging operation when receiving the downlink data of the terminal, which will cause a large amount of air interface resource overhead.

Each network slice includes: control function and user plane function. The control function provides users with specific services by controlling the user plane function. Since different network slices provide different services, the control functions of different network slices may be different. . Specifically, the control function may support functions such as mobility management, session management, or handover control. The user plane function is mainly responsible for routing terminal data, for example: the user plane function can be a gateway in the live network.

继续参见图4，图中示出的第一接入网络和第二接入网络可以是使用不同的接入技术(例如LTE(Long Term Evolution，长期演进)，WLAN(无线局域网)等)形成的接入网络，接入网络可以由一个或多个接入设备组成，例如基站。在本实施例中，基站泛指无线接入网络中通过无线接口将终端接入到网络的设备，例如，LTE中的eNB(evolved Node B,演进型基站)，未来5G网络中无线网络接入设备(实现类似于eNB的功能)，WLAN的AP(Access Point，无线访问节点)或TWAG(可信任无线接入网关)等。Continuing to refer to FIG. 4, the first access network and the second access network shown in the figure may be formed using different access technologies (such as LTE (Long Term Evolution, long-term evolution), WLAN (wireless local area network), etc.) An access network.

The information management function can interact with the control function in the network slice and the access device in the access network to obtain terminal information. The specific connection is shown in Figure 5. It should be noted that FIG. 5 only shows that the information management function interacts with the control function in one network slice. Of course, it can be understood that the information management function can also be shared by multiple network slices.

第一实施例first embodiment

参见图6，图中示出了通信方法的流程，该通信方法的执行主体可以是网络切片中的控制功能，具体步骤如下：Referring to FIG. 6, the flow chart of the communication method is shown in the figure. The execution subject of the communication method may be the control function in the network slicing, and the specific steps are as follows:

步骤601、控制功能从信息管理功能获取终端的信息，然后进入步骤602。Step 601, the control function acquires terminal information from the information management function, and then enters step 602.

具体地，在步骤601中，控制功能向信息管理功能发送第一请求消息，第一请求消息中携带有终端的标识；控制功能接收信息管理功能返回的第一回复消息，该第一回复消息中携带有终端的信息，其中，终端的信息包括：状态信息和/或位置信息，该状态信息可以是连接态或者空闲态，当终端处于连接态时，信息管理功能中存储有状态信息(连接态)和有效的位置信息，例如该位置信息可以是终端连接的接入设备的位置信息或标识，或者终端所在的小区标识等。在终端处于空闲态时，信息管理功能中没有存储有效的位置信息，例如信息管理功能中存储有状态信息(空闲态)和终端的跟踪区列表。Specifically, in step 601, the control function sends a first request message to the information management function, and the first request message carries the identifier of the terminal; the control function receives the first reply message returned by the information management function, and the first reply message contains Carry terminal information, wherein the terminal information includes: status information and/or location information, the status information can be connected state or idle state, when the terminal is in the connected state, the information management function stores state information (connected state ) and valid location information, for example, the location information may be the location information or identification of the access device connected to the terminal, or the identification of the cell where the terminal is located. When the terminal is in the idle state, no effective location information is stored in the information management function, for example, state information (idle state) and a tracking area list of the terminal are stored in the information management function.

步骤602、控制功能根据终端的信息，为终端触发连接建立过程或者寻呼操作。Step 602, the control function triggers a connection establishment process or a paging operation for the terminal according to the information of the terminal.

可选地，在步骤602中，当终端为空闲态，或者当终端的位置信息是跟踪区列表时，控制功能为所述终端触发寻呼操作，或者当终端为连接态，或者当终端的位置信息是终端连接的接入设备的信息(例如基站的标识或IP地址等)时，控制功能根据终端的信息中的位置信息向终端连接的接入设备发送连接建立请求消息，然后指示接入设备为终端建立无线承载，前述接入设备可以是基站，当然也并不限于此。Optionally, in step 602, when the terminal is in an idle state, or when the location information of the terminal is a tracking area list, the control function triggers a paging operation for the terminal, or when the terminal is in a connected state, or when the location of the terminal When the information is the information of the access device connected to the terminal (such as the identification or IP address of the base station, etc.), the control function sends a connection establishment request message to the access device connected to the terminal according to the location information in the information of the terminal, and then instructs the access device to To establish a radio bearer for the terminal, the aforementioned access device may be a base station, but of course it is not limited thereto.

参见图7，图中示出了第一实施例中连接建立过程或寻呼过程的流程图，具体步骤如下：Referring to Fig. 7, the flow chart of the connection establishment process or paging process in the first embodiment is shown in the figure, and the specific steps are as follows:

步骤701、网络切片内的用户面功能接收到用户的下行数据；Step 701, the user plane function in the network slice receives the user's downlink data;

步骤702、用户面功能向控制功能发送下行数据通知消息；Step 702, the user plane function sends a downlink data notification message to the control function;

步骤703、控制功能向信息管理功能发送第一请求消息，消息中携带有终端的标识，例如IMSI(International Mobile Subscriber Identification Number，国际移动用户识别码)或其他新定义的标识；Step 703, the control function sends a first request message to the information management function, and the message carries the identifier of the terminal, such as IMSI (International Mobile Subscriber Identification Number, International Mobile Subscriber Identification Number) or other newly defined identifiers;

步骤704、信息管理功能向控制功能返回第一回复消息，消息中携带有终端的信息。Step 704, the information management function returns a first reply message to the control function, and the message carries terminal information.

根据第一回复消息中携带的终端的信息不同，控制功能的行为也不同。如果控制功能判断终端的状态为连接态，或者控制功能判断接收到的终端的信息中包含有效的位置信息(例如位置信息为接入设备的标识或小区标识等)，则控制功能触发连接建立过程。后续过程如下：控制功能向终端连接的接入设备发送连接建立请求消息(例如现有技术中的初始上下文建立请求消息)，请求接入设备为终端建立空口连接(即为终端在该网络切片内建立的连接建立空口)，接入设备为这些连接建立空口之后向控制功能返回连接建立回复消息(例如现有技术中的初始上下文建立完成消息)，控制功能将接入设备的信息进而发送给用户面功能。According to the different information of the terminal carried in the first reply message, the behavior of the control function is also different. If the control function judges that the state of the terminal is connected, or the control function judges that the received terminal information contains valid location information (for example, the location information is the identifier of the access device or the cell identifier, etc.), the control function triggers the connection establishment process . The follow-up process is as follows: the control function sends a connection establishment request message (such as the initial context establishment request message in the prior art) to the access device connected to the terminal, and requests the access device to establish an air interface connection for the terminal (that is, the terminal is in the network slice). The established connection establishes an air interface), and after the access device establishes an air interface for these connections, it returns a connection establishment reply message (such as the initial context establishment completion message in the prior art) to the control function, and the control function sends the information of the access device to the user surface function.

如果控制功能判断终端为空闲态，或者当终端的位置信息是跟踪区列表时，则控制功能触发寻呼操作。If the control function determines that the terminal is in an idle state, or when the location information of the terminal is a tracking area list, the control function triggers a paging operation.

需要说明的是，如果终端连接的当前网络切片接收到终端的下行数据，且终端在连接的其他网络切片内进入连接态，信息管理功能存储有终端的位置信息，例如基站的信息，信息管理功能可能向UE发送消息，使UE发起业务请求过程。具体地，控制功能向信息管理功能发送第二请求消息，由信息管理功能向终端发送第三请求消息触发终端发起业务请求过程，其中，第三请求消息中携带有控制功能所在网络切片的信息。It should be noted that if the current network slice to which the terminal is connected receives the downlink data of the terminal, and the terminal enters the connected state in another connected network slice, the information management function stores the location information of the terminal, such as base station information, and the information management function It is possible to send a message to the UE to make the UE initiate a service request process. Specifically, the control function sends a second request message to the information management function, and the information management function sends a third request message to the terminal to trigger the terminal to initiate a service request process, wherein the third request message carries information about the network slice where the control function is located.

参见图8，图中示出了第一实施例中向UE发起业务请求的流程图，在图8中，步骤804中的第二回复消息和步骤806中的第三回复消息可以是确认消息。步骤803的第二请求消息中可能携带有接收到下行数据的网络切片的信息(如切片标识或控制功能的标识或业务标识或APN)。如果信息管理功能可以从步骤803的第二请求消息的源IP地址推断出发送该消息的网络切片，则步骤803的第二请求消息中可以不携带任何参数。Referring to FIG. 8 , it shows a flow chart of initiating a service request to UE in the first embodiment. In FIG. 8 , the second reply message in step 804 and the third reply message in step 806 may be confirmation messages. The second request message in step 803 may carry information about the network slice that has received the downlink data (such as a slice identifier or a control function identifier or a service identifier or APN). If the information management function can deduce the network slice sending the message from the source IP address of the second request message in step 803, the second request message in step 803 may not carry any parameters.

步骤805中的第三请求消息中携带有控制功能所在网络切片的信息(或者接收到下行数据的网络切片的信息)，例如切片标识或控制功能的标识或业务标识或APN。The third request message in step 805 carries information about the network slice where the control function resides (or information about the network slice that receives the downlink data), such as the slice identifier or the identifier of the control function or service identifier or APN.

步骤807中的终端可以根据第三请求消息判断出需要向对应的控制功能发起连接建立过程。In step 807, the terminal may determine according to the third request message that it needs to initiate a connection establishment process to the corresponding control function.

第二实施例second embodiment

在第一实施例的基础上，下面再介绍状态信息管理功能获取终端信息的过程。参见图9，图中示出了状态信息管理功能获取终端信息的过程，具体过程如下：On the basis of the first embodiment, the process of acquiring terminal information by the status information management function is introduced below. Referring to Figure 9, the figure shows the process of obtaining terminal information by the state information management function, and the specific process is as follows:

步骤901、控制功能向信息管理功能发送第一通知消息，第一通知消息中至少携带终端的标识。In step 901, the control function sends a first notification message to the information management function, and the first notification message carries at least the identifier of the terminal.

需要说明的是，第一通知消息还可能包括状态信息、位置信息和/或控制功能所在网络切片的信息，其中，状态信息可以是连接态或空闲态；位置信息可以是终端连接的接入设备的信息、跟踪区列表、或终端所在的小区的标识；网络切片的信息可以是切片标识或APN(Access Point Name，接入点名称)或其他新定义的标识。It should be noted that the first notification message may also include status information, location information and/or information about the network slice where the control function is located, where the status information may be connected or idle; the location information may be the access device connected to the terminal The information of the tracking area, or the identifier of the cell where the terminal is located; the information of the network slice may be a slice identifier or an APN (Access Point Name, access point name) or other newly defined identifiers.

步骤902、信息管理功能向控制功能返回第一确认消息。Step 902, the information management function returns a first confirmation message to the control function.

第三实施例third embodiment

在第一实施例的基础上，下面介绍信息管理功能获取终端信息的过程。参见图10，图中示出了信息管理功能获取终端信息的过程，具体过程如下：On the basis of the first embodiment, the process of acquiring terminal information by the information management function is introduced below. Referring to Figure 10, the figure shows the process of the information management function acquiring terminal information, the specific process is as follows:

步骤1001、控制功能检测终端的状态信息是否发生改变，当控制功能发现终端的状态信息发生改变，控制功能向信息管理功能发送第二通知消息。Step 1001, the control function detects whether the status information of the terminal has changed, and when the control function finds that the status information of the terminal has changed, the control function sends a second notification message to the information management function.

根据终端进入的状态不同，第二通知消息的参数不同。如果终端进入连接态，则第二通知消息的参数至少包括：终端的标识，状态信息(例如连接态)，和/或位置信息(例如基站标识或小区标识)，此时第二通知消息还可能包括控制功能所在的网络切片的信息，例如切片标识或APN。如果终端进入空闲态，则第二通知消息的参数至少包括终端的标识和状态信息(空闲态)，此时第二通知消息还可能包括控制功能所在的网络切片的信息，例如切片标识或APN。According to different states entered by the terminal, parameters of the second notification message are different. If the terminal enters the connected state, then the parameters of the second notification message at least include: the identity of the terminal, state information (such as connected state), and/or location information (such as base station identifier or cell identifier), and the second notification message may also Include information about the network slice where the control function resides, such as slice identity or APN. If the terminal enters the idle state, the parameters of the second notification message include at least the identification and status information (idle state) of the terminal. At this time, the second notification message may also include information about the network slice where the control function is located, such as slice identifier or APN.

步骤1002、信息管理功能存储终端的信息，并向控制功能返回第二确认消息。Step 1002, the information management function stores the information of the terminal, and returns a second confirmation message to the control function.

第四实施例Fourth embodiment

在第一实施例的基础上，介绍状态信息管理功能获取位置信息的过程。当处于连接态的UE发生移动时(例如UE连接的基站发生改变)，网络切片内的控制功能需要将该信息通知给信息管理功能。具体过程如图11所示。On the basis of the first embodiment, the process of obtaining location information by the state information management function is introduced. When the UE in the connected state moves (for example, the base station to which the UE is connected changes), the control function in the network slice needs to notify the information management function of the information. The specific process is shown in Figure 11.

步骤1101、控制功能检测位置信息是否发生改变，当控制功能发现位置信息发生改变时(例如终端连接的基站发生改变)，控制功能向信息管理功能发送第三通知消息。Step 1101, the control function detects whether the location information changes, and when the control function finds that the location information changes (for example, the base station connected to the terminal changes), the control function sends a third notification message to the information management function.

第三通知消息的参数至少包括终端的标识和位置信息(如基站标识或小区标识)，此时第三通知消息还可能包括控制功能所在的网络切片的信息，例如切片标识或APN。The parameters of the third notification message include at least the identifier and location information of the terminal (such as the base station identifier or the cell identifier). At this time, the third notification message may also include the information of the network slice where the control function is located, such as the slice identifier or APN.

步骤1102、信息管理功能更新终端的信息，并向控制功能返回第三确认消息。Step 1102, the information management function updates the information of the terminal, and returns a third confirmation message to the control function.

第五实施例fifth embodiment

当终端在多个网络切片进入连接态时，如果终端的信息发生改变(例如终端移动导致其连接的基站发生改变)，则需要将变化后的位置信息通知给信息管理功能。由于上述多个网络切片都能感知该事件，如果这些网络切片都向信息管理功能发送消息，则存在信令浪费的问题。在本实施例中，信息管理功能可从终端处于连接态的多个网络切片中选择一个，被选中的网络切片的控制功能需要向状态信息管理功能上报终端的信息，相应地，控制功能可以检测是否有向信息管理功能发送终端的信息的权限。When the terminal enters the connected state in multiple network slices, if the information of the terminal changes (for example, the base station connected to it changes due to the movement of the terminal), it is necessary to notify the information management function of the changed location information. Since the above-mentioned multiple network slices can perceive the event, if these network slices all send messages to the information management function, there will be a problem of signaling waste. In this embodiment, the information management function can select one of the multiple network slices where the terminal is in the connected state, and the control function of the selected network slice needs to report the information of the terminal to the state information management function. Correspondingly, the control function can detect Whether there is permission to send terminal information to the information management function.

基于第三实施例，当网络切片内的控制功能向信息管理功能表明终端进入连接态时，信息管理功能向控制功能返回第二确认消息时，可选地，在第二确认消息中携带指示信息，表明后续是否需要其上报位置信息。如果指示信息表明需要上报，则该网络切片内的控制功能需要执行第四实施例的过程；否则，网络切片内的控制功能不需要执行第四实施例的过程。Based on the third embodiment, when the control function in the network slice indicates to the information management function that the terminal enters the connected state, and the information management function returns the second confirmation message to the control function, the indication information may optionally be carried in the second confirmation message , indicating whether it needs to report location information in the future. If the indication information indicates that reporting is required, the control function in the network slice needs to execute the process of the fourth embodiment; otherwise, the control function in the network slice does not need to execute the process of the fourth embodiment.

对于信息管理功能指定的控制功能，如果终端在控制功能所在的网络切片进入空闲态，则信息管理功能需要判断终端是否在其他网络切片内处于连接态，如果是，则信息管理功能从这些网络切片中选择一个，由该网络切片内的控制功能上报终端的信息，具体过程如图12所示。否则，信息管理功能不执行任何操作。For the control function specified by the information management function, if the terminal enters the idle state in the network slice where the control function is located, the information management function needs to determine whether the terminal is in the connected state in other network slices, and if so, the information management function starts from these network slices Select one of them, and the control function in the network slice reports the information of the terminal. The specific process is shown in FIG. 12 . Otherwise, the information management function does nothing.

步骤1201、信息管理功能向控制功能发送第四通知消息，向控制功能说明当终端的信息(例如位置信息)发生改变时，控制功能需要上报该信息。Step 1201, the information management function sends a fourth notification message to the control function, explaining to the control function that when terminal information (such as location information) changes, the control function needs to report the information.

步骤1202、控制功能向状态信息管理功能返回第四确认消息。Step 1202, the control function returns a fourth confirmation message to the status information management function.

第六实施例Sixth embodiment

本实施例描述的是网络切片接收到终端的下行数据，网络切片内的控制功能没有从信息管理功能接收到有效的位置信息，而执行寻呼UE的过程。This embodiment describes that the network slice receives the downlink data of the terminal, but the control function in the network slice does not receive valid location information from the information management function, and executes the process of paging the UE.

该过程可能发生的场景如下：The possible scenarios for this process are as follows:

场景1、信息管理功能没有存储有效位置信息，即没有存储终端的位置信息或者终端管理功能存储的终端的位置信息是终端的跟踪区列表，终端在所有的网络切片内都处于空闲态；Scenario 1. The information management function does not store valid location information, that is, the location information of the terminal is not stored, or the location information of the terminal stored by the terminal management function is the tracking area list of the terminal, and the terminal is in an idle state in all network slices;

场景2、信息管理功能存储了终端的位置信息，但是终端连接的基站无法连接到上述网络切片，例如该基站与上述网络切片之间无连接。信息管理功能可通过配置信息判断终端已连接的基站与某个网络切片之间是否有连接。Scenario 2: The information management function stores the location information of the terminal, but the base station to which the terminal is connected cannot connect to the network slice, for example, there is no connection between the base station and the network slice. The information management function can determine whether there is a connection between the base station to which the terminal is connected and a certain network slice through configuration information.

参见图13，图中示出了寻呼的示意图，具体步骤如下：Referring to Figure 13, a schematic diagram of paging is shown in the figure, and the specific steps are as follows:

步骤1304、信息管理功能向控制功能返回第五回复消息，第五回复消息中携带提示信息，向控制功能说明不存在有效位置信息，或第五回复消息中携带有终端的状态信息(空闲态)，或第五回复消息中携带有终端的位置信息(跟踪区列表)。Step 1304, the information management function returns the fifth reply message to the control function, the fifth reply message carries prompt information, and explains to the control function that there is no valid location information, or the fifth reply message carries the status information of the terminal (idle state) , or the fifth reply message carries the location information (tracking area list) of the terminal.

步骤1305、控制功能向接入设备发送寻呼消息。寻呼消息中可能携带控制功能所在网络切片的信息。控制功能发送寻呼消息的范围可与现有机制类似，即向TA(Tracking Area，跟踪区)列表中的所有TA内的接入设备发送寻呼消息。Step 1305, the control function sends a paging message to the access device. The paging message may carry information about the network slice where the control function resides. The scope of the control function sending the paging message may be similar to the existing mechanism, that is, sending the paging message to all access devices in the TA in the TA (Tracking Area, tracking area) list.

第七实施例Seventh embodiment

本实施例描述的是网络切片接收到终端的下行数据，网络切片内的控制功能从信息管理功能接收到位置信息，而执行连接建立的过程。该过程发生的场景是信息管理功能存储有位置信息，例如终端已经在其他网络切片内进入连接态。如果运营商部署的基站不能连接所有的网络切片，信息管理功能还需要进一步判断终端连接的接入设备和上述网络切片是否有连接。具体过程如图14所示。This embodiment describes the process that the network slice receives the downlink data of the terminal, the control function in the network slice receives the location information from the information management function, and executes the process of connection establishment. The scenario where this process occurs is that the information management function stores location information, for example, the terminal has entered the connected state in other network slices. If the base station deployed by the operator cannot connect to all network slices, the information management function needs to further determine whether the access device connected to the terminal is connected to the network slice. The specific process is shown in Figure 14.

步骤1401、网络切片内的用户面功能接收到用户的下行数据；Step 1401, the user plane function in the network slice receives the user's downlink data;

步骤1402、用户面功能向控制功能发送下行数据通知消息；Step 1402, the user plane function sends a downlink data notification message to the control function;

步骤1403、控制功能向信息管理功能发送第六请求消息，第六请求消息中携带有终端的标识，例如IMSI或其他新定义的标识；Step 1403, the control function sends a sixth request message to the information management function, the sixth request message carries the identifier of the terminal, such as IMSI or other newly defined identifiers;

步骤1404、信息管理功能向控制功能返回第六回复消息，第六回复消息中携带终端的位置信息，如终端连接的基站的信息或小区标识。Step 1404, the information management function returns a sixth reply message to the control function, the sixth reply message carries the location information of the terminal, such as the information of the base station to which the terminal is connected or the cell identifier.

步骤1405、控制功能向基站发送初始上下文建立请求消息。Step 1405, the control function sends an initial context establishment request message to the base station.

步骤1406、基站为UE建立无线承载。Step 1406, the base station establishes a radio bearer for the UE.

步骤1409、用户面功能向控制功能返回修改承载回复消息。Step 1409, the user plane function returns a modify bearer reply message to the control function.

说明：图中的步骤1405至1409均为现有消息。如果基站不知道网络切片内的控制功能的信息，则需要对步骤1405进行扩展，在初始上下文建立消息中携带控制功能所在网络切片的信息，如果基站知道网络切片内的控制功能的信息(例如IP地址)，则不需要扩展步骤1405的初始上下文建立消息。Explanation: Steps 1405 to 1409 in the figure are all existing messages. If the base station does not know the information of the control function in the network slice, step 1405 needs to be extended to carry the information of the network slice where the control function is located in the initial context establishment message. If the base station knows the information of the control function in the network slice (such as IP address), then there is no need to extend the initial context establishment message of step 1405.

第八实施例Eighth embodiment

场景假设：终端在网络切片1和网络切片2内处于连接态，在网络切片3内处于空闲态；终端通过基站1连接到网络切片1，通过基站2连接到网络切片2；信息管理功能中存储的信息可以包括：<网络切片1：连接态，基站1>，<网络切片2：连接态，基站2>；网络切片3接收到终端的下行数据。Scenario assumption: the terminal is in the connected state in network slice 1 and network slice 2, and is in the idle state in network slice 3; the terminal is connected to network slice 1 through base station 1, and connected to network slice 2 through base station 2; the information management function stores The information may include: <network slice 1: connected state, base station 1>, <network slice 2: connected state, base station 2>; network slice 3 receives the downlink data of the terminal.

网络切片3内的控制功能从信息管理功能接收到位置信息，即基站1的位置信息和基站2的位置信息。网络切片3内的控制功能选择一个路由路径最短的接入设备(基站，例如距离SGW-U最近)，发起连接建立过程。如果建立失败，则选择次优的基站建立连接。The control function in the network slice 3 receives the location information from the information management function, that is, the location information of the base station 1 and the location information of the base station 2 . The control function in the network slice 3 selects an access device (base station, for example, the closest to the SGW-U) with the shortest routing path, and initiates a connection establishment process. If the establishment fails, a suboptimal base station is selected to establish a connection.

第九实施例Ninth embodiment

在本实施例中，某个网络切片接收到终端的下行数据，此时终端已在其他网络切片内进入连接态，状态信息管理功能中存储有终端的位置信息，如基站的信息。信息管理功能触发终端发起业务请求过程，以建立用户面连接。具体过程如图15所示。In this embodiment, a certain network slice receives the downlink data of the terminal. At this time, the terminal has entered the connected state in another network slice, and the state information management function stores the location information of the terminal, such as the information of the base station.

步骤1506、终端向信息管理功能返回第七确认消息。Step 1506, the terminal returns a seventh confirmation message to the information management function.

步骤1507、终端发起业务请求过程。Step 1507, the terminal initiates a service request process.

在上述场景中，如果终端未在其他网络切片内进入连接态，则不执行图虚框内的步骤(步骤1505～1507)，且在步骤1504中，状态信息管理功能向控制功能返回的第五确认消息中携带有原因或原因值，表明终端未在其他网络切片内进入连接态。此时，控制功能发起寻呼操作。In the above scenario, if the terminal does not enter the connected state in other network slices, the steps in the virtual frame in the figure (steps 1505-1507) are not executed, and in step 1504, the status information management function returns the fifth The confirmation message carries a reason or a reason value, indicating that the terminal has not entered the connected state in other network slices. At this point, the control function initiates a paging operation.

第十实施例Tenth embodiment

参见图16，图中示出了第十实施例中通信方法的流程，该通信方法包括：Referring to Figure 16, the figure shows the flow of the communication method in the tenth embodiment, the communication method includes:

步骤1601、信息管理功能向控制功能发送终端的信息，由控制功能根据所述终端的信息触发对终端的连接建立过程或者触发对终端的寻呼操作；或Step 1601, the information management function sends the information of the terminal to the control function, and the control function triggers a connection establishment process for the terminal or triggers a paging operation for the terminal according to the information of the terminal; or
