Abstract: This application discloses a communication method, an apparatus, and a device, to ensure continuity of service transmission. The method includes: An AS sends a service data packet of a first service to a terminal device over a multicast session. When a condition for the terminal device to perform inter-communication system switching is met or the terminal device performs the inter-communication system switching, the terminal device may send first information to trigger the AS to send the service data packet of the first service to the terminal device in a unicast transmission mode. In this way, an inter-communication system switching procedure of the terminal device does not affect transmission of the first service of the terminal device, to ensure continuity of service transmission.

Abstract: This application provides a communication method and a communication apparatus. In a technical solution of this application, when a preset condition is met, an access network device notifies user equipment that a multicast session is to be released or is to be deactivated. If the multicast session is being used or is to be used, the user equipment may feed back to the access network device that the user equipment is still interested in a multicast service. The access network device may determine, based on whether the feedback from the user equipment is received within a preset time period, whether to continue to release or deactivate the multicast session. In this way, when user equipment in an idle state can receive multicast data, this technical solution can properly manage the multicast session.

Abstract: This application discloses a communications method and apparatus. The method includes: receiving, by a radio access network (RAN) node, a first message from an access and mobility management function (AMF) node, where the first message includes specified area related information of a terminal device, and the specified area related information is used to indicate a specified area of the terminal device; and when the RAN node determines, based on the specified area related information and first location information of the terminal device, that the terminal device moves out of the specified area, sending, by the RAN node, the first location information or first indication information to the AMF node or an SMF node, where the first indication information is used to indicate that the terminal device already moves out of the specified area.

Abstract: This application discloses a multicast/broadcast communication method and an apparatus, and relates to the field of wireless communication. The method includes: receiving first information from an application function network element, and determining a target MB-SMF network element based on the first information. The first information includes a first identifier of a first MBS session and information about an MBS service area. The first MBS session is for transmitting data to the MBS service area. The target MB-SMF network element supports the MBS service area, and the target MB-SMF network element is configured to create the first MBS session. In the foregoing method, the target MB-SMF network element may be determined based on the first identifier of the first MBS session and the information about the MBS service area. Therefore, the target MB-SMF network element can serve the MBS service area.
