Abstract: Embodiments of this application provide a multicast/broadcast service communication method, an apparatus, and a system. The method includes: a first terminal device receives first information, where the first information indicates activation or release of a first multicast/broadcast session, the first terminal device joins the first multicast/broadcast session, the first terminal device is in a radio resource control inactive state, and the first multicast/broadcast session is used for transmitting a first multicast/broadcast service; and the first terminal device enters a connected state or keeps in the radio resource control inactive state based on the first information. According to the method, a terminal device that is in a radio resource control inactive state and that is allowed to receive a multicast/broadcast service in this state does not enter a connected state, thereby helping reduce network overheads.

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 handover method and a communication apparatus are provided. The method includes: A target access network device obtains a first message and information used for transmitting multicast data, where the first message is used for requesting to establish a resource for handing over a terminal device to the target access network device. The target access network device sends a second message, where the second message indicates the established resource on the target access network device; receives a first packet from a user plane network element, where the first packet corresponds to the information used for transmitting the multicast data; and sends the first packet to the terminal device. In this way, the terminal device is handed over from a source access network device to the target access network device when the terminal device receives the multicast data.

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.

Abstract: This application discloses example communications methods and apparatuses. One example method includes receiving, by a core network element, a first request message from a terminal, where the first request message is used to request information used for PC5 interface-based communication of the terminal. The core network element can then send, to the terminal and based on the first request message, a quality of service (QoS) rule used for the PC5 interface-based communication.
