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: Embodiments of this application relate to the field of communications technologies, and disclose an application programming interface (API) topology hiding method, a device, and a system. A common API framework core function (CCF) receives, from a topology hiding request entity, a request message that includes information about an API and that is used to request to hide an API exposing function (AEF) that provides the API. Based on the request message, a topology hiding entry point used by an API invoker to invoke the API is determined. An identifier of the API and an identifier of the AEF that provides the API are sent to the topology hiding entry point so that the topology hiding entry point hides the AEF that provides the API.

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.
