Abstract: This application provides a multicast/broadcast service transmission method, a core network element, and a terminal device. The method performed by a first core network element includes: obtaining a multicast/broadcast access type supported by a terminal device that is located in a first service area of a multicast/broadcast service and that belongs to a group corresponding to the multicast/broadcast service; determining a multicast/broadcast transmission type of the multicast/broadcast service in the first service area based on the multicast/broadcast access type supported by the terminal device; and notifying an access network element corresponding to the multicast/broadcast service to use the multicast/broadcast transmission type to transmit data of the multicast/broadcast service. According to the method, the first core network element may determine a specific RAT based on which multicast/broadcast transmission is performed, to better adapt to a case in which a terminal device supports a plurality of RATs, and improve multicast/broadcast transmission efficiency.

Abstract: The technology of this application relates to a method for selecting a network element in a communication sensing service and a communication apparatus. In the method, a radio access network element, an access and mobility management function network element, and a sensing network element each having a sensing capability can register the sensing capability with a network repository function network element. After receiving a sensing service request, a network exposure function network element, the access and mobility management function network element, or the sensing network element selects an appropriate network element based on the sensing capability of each network element (for example, the radio access network element, the access and mobility management function network element, or the sensing network element) registered with the network repository function network element, to select the appropriate network element for a sensing service, to support the sensing service in an end-to-end manner.

Abstract: An authorization method includes receiving, by a policy control function device of a relay terminal, a request message from an access and mobility management function device of the relay terminal. The request message includes an identifier of a remote terminal and an identifier of the relay terminal. The method also includes determining, by the policy control function device, an authorization result based on the identifier of the remote terminal and the identifier of the relay terminal. The authorization result indicates whether the relay terminal and the remote terminal are authorized to establish a relay service relationship. The method further includes sending, by the policy control function device, the authorization result to the access and mobility management function device.

Abstract: A data processing method and a data processing apparatus are described that simplify an operation procedure in which an access and mobility management function (AMF) entity delivers a quality of service (QoS) parameter to an access network device to which the terminal device requests to connect or a target access network device to which the terminal device requests to be handed over, and reduce signaling overheads. The described method includes an access and mobility management function AMF entity receiving a quality of service QoS parameter used for a ProSe communication 5 (PC5) interface communication of a terminal device. The AMF entity stores the QoS parameter. When a preset condition is satisfied, the AMF entity sends the stored QoS parameter to a first access network device.
