Abstract: A service authorization method and a communications apparatus to resolve a problem that, in a scenario in which a second server is discovered by a client, a first server fails to obtain service authorization to access the second server, so as to reduce a security risk of a service-based network. The method includes: applying, by the client on behalf of the first server, for an access token for the first server to access the second server, and notifying the access token to the first server. Alternatively, the first server applies for the access token based on an instance identifier or a resource identifier of the second server that is provided by the client.

Abstract: This application provides an indication information transmission method and a related apparatus. The method includes: An intermediate session management network element sends third indication information to a target user plane network element based on second indication information from a session management network element, so that the target user plane network element buffers an uplink packet based on the third indication information. When learning that handover to a target application network element has been completed, the session management network element may send fourth indication information to the intermediate session management network element, so that the intermediate session management network element sends fifth indication information to the target user plane network element based on the fourth indication information, and the target user plane network element forwards the uplink packet based on the fifth indication information.

Abstract: A data transmission method and apparatus are provided. One example method involves establishing two tunnels between an access network device and a user plane function network element, where the two tunnels may be tunnels used for downlink data transmission or tunnels used for uplink data transmission. When communicating with the user plane function network element, the access network device may transmit two data packets. In this way, when one data packet is lost, the receive end may further receive the other data packet.

Abstract: A method for paging a user equipment includes: receiving, by the user equipment, an area identifier and a corresponding layering type, where the layering type is a capacity-oriented type or a coverage-oriented type; if an area currently accessed by the user equipment is a capacity-oriented area, switching, by the user equipment, to a coverage-oriented area based on the layering type when changing to an idle state; and receiving a paging message for the coverage-oriented area. Alternatively, the method includes: determining, by a network device, a coverage-oriented area in a registration area of a user equipment based on an area identifier and a corresponding layering type, and paging the user equipment in the coverage-oriented area.
