Abstract: A paging method and apparatus are provided to simplify a prior-art paging process. The method includes: receiving, by an access device, downlink data, where the downlink data includes a first identifier of a terminal; determining a paging identifier based on the first identifier; and sending, by the access device, a paging message to the terminal, where the paging message carries the paging identifier. After the access device receives the downlink data, the access device can initiate the paging process without using a control plane network element device. The advantages of the innovative paging methods disclosed herein include reduced signaling, shortened signaling transmission, and simplified paging process.

Abstract: A communication method and apparatus. One method includes: a session management network element obtains an identifier of a DN accessed by a terminal device and/or an identifier of a network slice accessed by the terminal device. The session management network element determines, based on the identifier of the DN and/or the identifier of the network slice, a service type requested by the terminal device. The session management network element requests, from an access network device on a satellite, tunnel information corresponding to the service type. The session management network element receives, from the access network device, the tunnel information corresponding to the service type.

Abstract: This application provides a communication method and apparatus. The method includes: A first session management function network element determines whether a first session management function network element is able to serve a first data network access identifier (DNAI). The first session management function network element sends first information to a first access and mobility management function network element when the first session management function network element is able to serve the first DNAI, where the first information is used by the first access and mobility management function network element to remove an intermediate session management function network element.

Abstract: In a media data transmission method, an access network device receives layered coding information of a media flow, where the media flow is a target service; the access network device determines a plurality of multicast groups based on the layered coding information and information about terminal devices that access the target service; and the access network device sends a media data packet of the target service to the terminal devices based on the plurality of multicast groups. By using the method, multicast grouping may be performed on a plurality of terminal devices that access a same service, and further differentiated transmission is performed on media data of the same service. This improves a data transmission speed of the access network device, and improves a data throughput in a signal coverage area of the access network device.

Abstract: This application provides a method for controlling a terminal device to access a network, and a communication apparatus. The method includes: An access network device sends, to a mobility management network element, identification information of a network selected by a terminal. When a core network does not determine whether the terminal device is allowed to access the network, the mobility management network element sends, to the terminal device, information indicating not to initiate a service. According to the method, the terminal device is prevented from initiating a service before the core network verifies whether the terminal device is allowed to access the network, so that compliance with regulatory requirements is ensured.
