In the description of the embodiments of the present application, the term "corresponding" may indicate that there is a direct correspondence or an indirect correspondence between the two, or may indicate that there is an association between the two, or may indicate a relationship between the two and the indicated, configured, etc.

In order to clearly illustrate the ideas of embodiments of the present application, first, a communication system is described. . . Is briefly described.

The service architecture is an important feature in the 5G network architecture, that is, the core network element can provide specific services, and provide services for other network elements through defined API interfaces. Fig. 2 shows a system architecture diagram of a mobile terminal accessing a mobile network. The UE is connected with a base station through an Access Stratum (AS), and exchanges Access Stratum information and wireless data transmission; the UE performs Non-access stratum (NAS) connection with the mobile management function AMF, and interacts NAS messages. The AMF is responsible for managing mobility of the UE, the session management function (Session Management Function, SMF) is responsible for session management of the UE, and the AMF is responsible for forwarding session management related messages between the UE and the SMF in addition to mobility management of the mobile terminal. The policy control function (Policy Control Function, PCF) is responsible for formulating policies related to mobility management, session management, charging, etc. for the UE. The user plane function UPF is connected with the base station and an external data network for data transmission.

Further, two services are defined in the service architecture, namely "Request-Response", which is that the provider sends a reply message immediately after receiving the Request and generally replies only once, and "Subscribe-Notify", which is that the provider receives the content of the Response immediately after receiving the Subscribe or after delaying Notify, and possibly also sends Notify multiple times later.

On the other hand, communication may be performed in a serviceization architecture using a "Restful HTTP" (a hypertext transfer protocol HTTP interface designed according to the representational state transfer (Representational State Transfer, rest) style). For example, the core network control plane network element in fig. 2 may provide specific service functions to other network elements through a service interface (such as the Nnssf interface, the Npcf interface, the Nudm interface, etc. in fig. 2), and the network element providing the service may be referred to as a "service provider", and the network element using the service may be referred to as a "service consumer". For example, when a certain network element needs to use a certain service, it may interact with the NRF first, provide the NRF with information of the required service, return the NRF with information of the service provider, and then the network element may interact with the service provider directly to obtain the corresponding service.

At present, only the NRF network element in the service architecture can perform the search of the core network element described above, and for other important scenes such as a scene of device-to-device D2D (e.g. UE-to-UE direct communication) and the like, the current service architecture cannot be realized yet, and needs to be further expanded and optimized.

In the following embodiments, description will be made taking an example in which both the provider and the consumer of the service are terminal devices, and registration and lookup are performed through the core network element NRF.

Process 1: registration request procedure

In this embodiment, both the service provider and the consumer are terminal devices, respectively denoted as UE-1 and UE-2, where UE-1 registers through the core network element NRF, and the registration request process may refer to fig. 6, and UE-1 may send a registration request through NAS messages, which is described in detail below.

1. The UE-1 may be a Service provider (Service provider), and the UE-1 sends a registration request message to the NRF, where the request message includes a Service identifier (or Service ID), specifically:

● The service identity represents the identity of the service or application that the UE-1 device itself supports (or: allows, activates, requests); the following are exemplary:

analysis identity (analysis ID): a data processing manner that may indicate that the UE-1 is capable of performing or providing, and/or an artificial intelligence service;

Artificial intelligence model identification (AI model ID): AI models that may be used to indicate UE-1 support or use;

application ID: indicating the applications supported by UE-1.

Further, the registration request message may further include at least one of the following parameters:

3. the NRF feeds back the query result (e.g., the query is successful) and the corresponding UE information (e.g., the identity, address, etc. of UE-1) in the reply message, where the UE information is used for UE-2 discovery or finds UE-1.

Wherein, optionally, the reply message may further include a corresponding temporary identifier/code, where the temporary identifier/code may be the same as the temporary identifier/code fed back to UE-1 by NRF in the registration process. Optionally, the NRF may update the temporary identity/code again to UE-2, if needed later.

In this embodiment, the connection between UE-2 and UE-1 may be established in at least one of the following ways, which are described in detail below.

Mode 1: establishing a connection via a PC5 interface

Referring to fig. 8, the UE-2 establishes a connection with the UE1 through a PC5 interface according to information obtained from the network side.
