Abstract: A communication method and apparatus. One method includes: a session management network element obtains an identifier of a DN accessed by a terminal device and/or an identifier of a network slice accessed by the terminal device. The session management network element determines, based on the identifier of the DN and/or the identifier of the network slice, a service type requested by the terminal device. The session management network element requests, from an access network device on a satellite, tunnel information corresponding to the service type. The session management network element receives, from the access network device, the tunnel information corresponding to the service type.

Abstract: The present disclosure provides an authorization method and an apparatus to verify whether a terminal device is authorized to provide or use a relay service. The method includes: a policy control function network element receives an authorization request message from an access and mobility management function network element, and determines, based on proximity-based services authorization information of a terminal device, whether the terminal device is authorized to use a relay service code. The authorization request message includes the relay service code from the terminal device. The authorization request message is for requesting to verify whether the terminal device is authorized to use the relay service code. The relay service code identifies a connection service provided by a relay device for a remote device, and the proximity-based services authorization information indicates a relay service with which the terminal device is authorized.

Abstract: This application provides a method for performing data transmission by two terminal devices and an apparatus, so that only a spectrum resource needs to be occupied or fewer spectrum resources need to be occupied, and fewer spectrum resources are consumed, thereby helping alleviate a strain on spectrum resources. The method includes: A first core network device determines that a first terminal and a second terminal are in a mutual backup relationship. The first core network device sends pairing indication information to a base station, where the pairing indication information indicates that the first terminal and the second terminal are in the mutual backup relationship.

Abstract: A method and an apparatus for establishing secure communication. The method includes: a terminal device receives a first message from a first network element, where the first message includes an identifier of a second network element and first indication information, and the first indication information indicates a candidate authentication mechanism associated with the second network element. The terminal device establishes a communication connection with the second network element based on the candidate authentication mechanism. The terminal device may obtain an authentication mechanism of the dynamically configured second network element, to meet a requirement for establishing a secure communication connection through authentication in an MEC architecture.

Abstract: This application provides a communication system, method, and apparatus, to resolve a prior-art problem that a terminal device does not know how to initiate a correct procedure to establish a communication connection to an application function AF to obtain a business service. A principle of the method is as follows: An AF sends a service mode supported by the AF to UE by using a core network. Therefore, before initiating a service to the AF, the UE can sense the service mode supported by the AF, and the UE initiates a correct connection establishment procedure to the AF based on the service mode supported by the AF.

Abstract: This application provides a communication system, method, and apparatus. The system is applied to implement AKMA service-based data transmission between a terminal device and an application function network element, and the system includes an AKMA anchor function network element and a network exposure function network element. The network exposure function network element obtains first identification information from a unified data management network element, where the first identification information is used to determine an authentication server function network element corresponding to the terminal device, and sends the first identification information to the AKMA anchor function network element. The AKMA anchor function network element obtains, from the unified data management network element based on the first identification information, identification information of the authentication server function network element corresponding to the terminal device.

Abstract: A communication method includes receiving, by a policy control network element executed by a processor, first information. The first information is service information or a traffic steering requirement. The traffic steering requirement includes at least one service function. The communication method also includes obtaining, by the policy control network element, first traffic steering policy information from a first network element based on the first information. The first traffic steering policy information indicates network elements corresponding to the at least one service function and a sequence in which service data passes through the network elements corresponding to the at least one service function.

Abstract: The present disclosure relates to communication methods and apparatus. One example method includes receiving, by a target service entity, a first request message from a first participating service entity, and sending, by the target service entity, a first response message to the first participating service entity. The first request message comprises an identity of a target multicast bearer and a group identity of a terminal group. The first response message is used to instruct the first participating service entity to use the target multicast bearer to send service data of the terminal group.
