Abstract: This disclosure provides a communication method, apparatus, and system. The method is performed by a remote terminal, which receives first policy information from a policy control function network element, where the first policy information includes a relay mode corresponding to a first application of the remote terminal, determines a first relay mode based on the first policy information, and transmits data of the first application in the first relay mode to a relay device. In the method, the remote terminal selects a relay mode for individual application and deliver data of the individual application in the selected relay mode such that different relay modes can be applied to different applications. In this way, requirements of different applications are met, and collaboration between different relay modes is enabled.

Abstract: A data communication method includes receiving a first message. The first message includes an identifier of a second terminal, and the first message requests to perform communication of a first application between a first terminal and the second terminal. The data communication method also includes sending first information to an access network device based on the first message. The first information includes an identifier of a first bearer and an identifier of a second bearer, the first bearer is for transmitting data of the first application for the first terminal, the second bearer is for transmitting the data of the first application for the second terminal, and the first information is used by the access network device to directly forward the data of the first application between the first terminal and the second terminal.

Abstract: An authorization method and an apparatus are provided. An access management network element obtains operation allowed indication information and an authorization condition, where the operation allowed indication information indicates that a terminal device is allowed to provide a connection service, and the authorization condition includes an authorized location range of the connection service and/or an authorized time range of the connection service. The access management network element determines an authorization result based on the authorized location range and/or the authorized time range, and sends the authorization result to an access network element accessed by the terminal device, where the authorization result indicates that the terminal device is not allowed to provide the connection service, or the terminal device is allowed to provide the connection service.

Abstract: The disclosure provides a communication method and apparatus. The method is performed by an access network device, and includes: receiving reference information of a first multicast/broadcast service (MBS) session from an access and mobility management network element, where the reference information of the first MBS session indicates a feature of the first MBS session; and triggering, based on the reference information, a first receive end corresponding to the first MBS session to enter an idle state or a radio resource control (RRC) inactive state. In this application, a receive end corresponding to an MBS session is not always in an RRC connected state, and the method can avoid maintaining a large quantity of receive ends corresponding to the MBS session in the RRC connected state for a long term, and further save processing resources of the access network device.
