摘要： This application provides a satellite ephemeris update method and a communication apparatus. The method includes: A first network element determines whether an ephemeris in a terminal device needs to be updated; and the first network element sends first information to the terminal device, where the first information includes an updated ephemeris or indication information indicating that the ephemeris does not change. Optionally, the first network element may be a core network element. For example, the first network element may be an AMF, an SMF, or the like. According to the ephemeris update method provided in this application, the terminal device is timely notified of ephemeris update information, so that the terminal device can timely and effectively obtain the updated ephemeris. This reduces a delay of accessing a satellite cell by the terminal device, and improves communication efficiency and user experience.

摘要： The present invention relates to a paging processing method, user equipment and system. One method includes: receiving, by a user equipment, a paging message sent by a mobility management network element; sending, by the user equipment, a message for location update according to a value of a temporary identity (TIN) used for next update; and receiving, by the mobility management network element, the message for location update, and acquiring a bearer context of the user equipment. In the embodiments of the present invention, after receiving the paging message, the user equipment sends the message for location update after determining the value of the TIN of the user equipment, and after receiving the message for location update, the mobility management network element acquires the bearer context, so that the bearer context on the mobility management network element on the network side where the user equipment is located and the bearer context on the user equipment may keep consistent, thereby further overcoming a problem of a loss of a part of bearers or setup of a bearer with inconsistent bearer contexts at two ends in a paging process, ensuring normal use of a service, and improving user experience.

摘要： This application provides a wireless network communication method, a network device, and a terminal. The method includes: An uncrewed aerial vehicle traffic management entity receives an authorization request. The uncrewed aerial vehicle traffic management entity sends an authorization response. The authorization request is used to request authorization to control an uncrewed aerial vehicle by a terminal, and the authorization response is used to indicate whether the terminal is allowed to control the uncrewed aerial vehicle. Alternatively, the authorization request is used to request authorization to pair a terminal with an uncrewed aerial vehicle controller, and the authorization response is used to indicate whether the terminal is allowed to be paired with the uncrewed aerial vehicle controller. An uncrewed aerial vehicle traffic management entity in a mobile communication network is used to authorize or pair an uncrewed aerial vehicle controller and an uncrewed aerial vehicle, thereby facilitating long-distance communication between the uncrewed aerial vehicle controller and the uncrewed aerial vehicle.
