Abstract: Embodiments of this application relate to the field of communication technologies, and provide a method for determining an edge configuration server and an apparatus, to select a more proper edge configuration server for a terminal apparatus. The method includes: A core network element determines, based on a mobile network accessed by a terminal apparatus, that an edge configuration server serving the terminal apparatus is a first edge configuration server, where at least one mobile network corresponding to the first edge configuration server includes the mobile network accessed by the terminal apparatus. The core network element sends, to the terminal apparatus, information indicating the first edge configuration server.

Abstract: This application discloses a communications system, a communication method, and an apparatus thereof. The system includes: a multicast session management network element, an access and mobility management network element and a user plane function network element. The multicast session management network element sends a first multicast session request carrying a multicast session context to the access and mobility management network element to request to establish a multicast session based on the multicast session context; and sends a second multicast session request to the user plane function network element, where the second multicast session request carries user plane forwarding-related information indicating a user plane forwarding rule of the multicast session. The access and mobility management network element sends the first multicast session request to an access network node. The user plane function network element sets, based on the user plane forwarding-related information, the user plane forwarding rule of the multicast session.

Abstract: A communication method and an apparatus are provided. The method includes: A common application programming interface framework core function (CCF) network element first sends reference information of an application to a first network element. Therefore, the first network element determines network slice information corresponding to the application; and then the first network element sends the determined network slice information to the CCF network element. In this way, the CCF network element may determine the network slice information corresponding to the application, so that when an API invoker network element searches for an API, the CCF network element can accurately find, based on an API inquiry parameter, the API from a network slice corresponding to the network slice information.

Abstract: A multicast communication method and a communication apparatus provide for transmission of data of a multicast service using a PDU session established by a terminal device to improve network element utilization. An AF network element sends first multicast service indication information to a session management network element indicating a first multicast service. The session management network element sends, based on the first multicast service indication information, multicast service information to an access network device that serves a terminal device. The access network device establishes an association relationship between the terminal device and the first multicast service based on the multicast service information, so that the access network device can send, when receiving data of the first multicast service, the data of the first multicast service to the terminal device using a PDU session.

Abstract: The present disclosure relates to broadcast bearer management methods and devices. One example method includes receiving, by a first bearer management server (BMS), a first message sent by a server, where the first message includes a group identifier of a service group, determining, by the first BMS, a first broadcast bearer for the service group based on the first message, and sending, by the first BMS, a second message to the server, where the second message carries user plane information of the first broadcast bearer.
