通常，服务化架构是第五代移动通信5G网络架构中的重要特征，在服务化架构中，核心网控制面网元可以通过服务化接口将特定的服务功能提供给其他网元，提供服务的网元可称为“服务提供者”，使用服务的网元可称为“服务消费者”，例如，当某网元需要使用某种服务时，其可以先与网络仓储功能(Network Repository Function，NRF)交互，向NRF提供需要的服务的信息，NRF返回服务提供者的信息，然后该网元可与服务提供者直接交互，得到相应的服务。目前服务化架构中仅NRF网元可执行类似的处理，对于一些重要场景例如设备至设备D2D场景等，目前的服务化架构还无法实现上述处理或交互。Generally, service-oriented architecture is an important feature of the fifth-generation mobile communication 5G network architecture. In the service-oriented architecture, core network control plane network elements can provide specific service functions to other network elements through service-oriented interfaces. Network elements can be called "service providers", and network elements that use services can be called "service consumers." For example, when a network element needs to use a certain service, it can first communicate with the Network Repository Function (Network Repository Function, NRF) interacts to provide required service information to NRF, and NRF returns the service provider's information, and then the network element can directly interact with the service provider to obtain the corresponding service. In the current service-based architecture, only NRF network elements can perform similar processing. For some important scenarios such as device-to-device D2D scenarios, the current service-based architecture cannot yet implement the above processing or interaction.

为了清楚地阐述本申请实施例的思想，首先对通信系统中。。。的处理过程进行简要描述。In order to clearly explain the ideas of the embodiments of the present application, first the communication system is discussed. . . The processing process is briefly described.
服务化架构是5G网络架构中的重要特征，即核心网网元可以提供特定的服务，并通过定义的API接口供其他网元调用服务。图2示出了一种移动终端接入移动网络的系统架构图。其中，UE与基站进行接入层(Access Stratum，AS)连接，交互接入层消息及无线数据传输；UE与移动管理功能AMF进行非接入层(Non-access stratum，NAS)连接，交互NAS消息。AMF负责对UE移动性的管理，会话管理功能(Session Management Function，SMF)负责对UE的会话管理，AMF在 对移动终端进行移动性管理之外，还负责将从会话管理相关消息在UE和SMF之间的转发。策略控制功能(Policy Control Function，PCF)负责制定对UE的移动性管理、会话管理、计费等相关的策略。用户面功能UPF与基站及外部数据网络相连进行数据传输。Service-oriented architecture is an important feature of 5G network architecture, that is, core network elements can provide specific services and allow other network elements to call services through defined API interfaces. Figure 2 shows a system architecture diagram for a mobile terminal to access a mobile network. Among them, the UE and the base station are connected to the Access Stratum (AS), exchanging access layer messages and wireless data transmission; the UE and the mobility management function AMF are connected to the Non-access stratum (NAS) to exchange NAS information. The AMF is responsible for managing the mobility of the UE, and the Session Management Function (SMF) is responsible for the session management of the UE. In addition to mobility management of the mobile terminal, the AMF is also responsible for transferring session management related messages between the UE and the SMF. forwarding between. The Policy Control Function (PCF) is responsible for formulating policies related to UE mobility management, session management, and charging. The user plane function UPF is connected to the base station and external data network for data transmission.
进一步，服务化架构中定义了两种服务，一是“Request-Response”(请求-响应)，二是“Subscribe-Notify”(订阅-通知)，其中前者是提供者接收到请求后立即发送回复消息且一般只回复一次，后者是提供者接收Subscribe后立即或延时Notify响应的内容，后续可能还会发送多次Notify。Furthermore, two services are defined in the service-oriented architecture, one is "Request-Response" (request-response), and the other is "Subscribe-Notify" (subscription-notification). The former is that the provider sends a reply immediately after receiving the request. The message generally only responds once. The latter is the content of the provider's immediate or delayed Notify response after receiving the Subscribe. The provider may also send multiple Notify messages in the future.
另一方面，在服务化架构中可使用“Restful HTTP”(一种按照表述性状态转移(Representational State Transfer，Rest)风格设计的超文本传输协议HTTP接口)方式进行通信。例如，图2中的核心网控制面网元可以通过服务化接口(如图2中Nnssf接口、Npcf接口、Nudm接口等)将特定的服务功能提供给其他网元，提供服务的网元可称为“服务提供者”，使用服务的网元可称为“服务消费者”。例如当某网元需要使用某种服务时，其可以先与NRF交互，向NRF提供需要的服务的信息，由NRF返回服务提供者的信息，然后该网元可与服务提供者直接交互，得到相应的服务。On the other hand, "Restful HTTP" (a Hypertext Transfer Protocol HTTP interface designed in the Representational State Transfer (Rest) style) can be used for communication in a service-oriented architecture. For example, the core network control plane network element in Figure 2 can provide specific service functions to other network elements through service-oriented interfaces (Nnssf interface, Npcf interface, Nudm interface, etc. in Figure 2). The network element that provides services can be called As a "service provider", the network elements using the service can be called "service consumers". For example, when a network element needs to use a certain service, it can first interact with the NRF, provide the required service information to the NRF, and the NRF returns the service provider's information. Then the network element can directly interact with the service provider, and get Corresponding services.
目前，服务化架构中仅NRF网元可执行以上描述的核心网网元的查找，对于除此之外的其他重要场景，例如设备至设备D2D(如UE与UE直通)等场景，目前的服务化架构还无法实现，有待进一步扩展和优化。Currently, in the service-based architecture, only NRF network elements can perform the above-described search for core network elements. For other important scenarios, such as device-to-device D2D (such as UE-to-UE direct connection), the current service The centralized architecture cannot yet be realized and needs to be further expanded and optimized.
