Abstract: A wireless network communication method, a network device, and a terminal, where 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.

Abstract: This application provides a communication method and an apparatus. The communication method includes: A terminal device in a satellite service range receives first indication information indicating the terminal device to notify a network when the terminal device is in an idle state or a suspended state and is about to leave the satellite service range. The terminal device in the idle state or the suspended state determines that the terminal device is about to leave the satellite service range, and in this case, reports second indication information indicating that the terminal device is about to leave the satellite service range. In this way, a network side learns whether the terminal device in the idle state or the suspended state has left the satellite service range, thereby avoiding invalid paging.

Abstract: In a communication method when a preset quantity of terminal devices is allowed to simultaneously use a user identifier and a terminal device expects to use the user identifier, the terminal device sends a first message including the user identifier to a first network element. The first network element determines, based on information about the user identifier, whether the first terminal device is allowed to use the user identifier.

Abstract: This application provides a communication method and apparatus. The method includes: A first access network element determines that a terminal device is in a suspended state and that the first access network element cannot serve the terminal device when the terminal device is recovered to a connected state. The first access network element sends a context of the terminal device to a second access network element. The context is used by the terminal device to be recovered to the connected state. In the method, when determining that the terminal device is in the suspended state and that the first access network element cannot subsequently serve the terminal device, the first access network element can actively send the context of the terminal device to the second access network element.

Abstract: Methods, systems, and apparatus for rate control are provided. In one aspect, a rate control method includes: receiving, by a control device, a connection establishment request from a terminal, the connection establishment request being for establishing a connection for the terminal to transmit data, and sending, by the control device, rate control time management information to a data sending device. The data sending device is configured to perform rate control over the data sent through the connection based on the time management information. The ratio control time management information includes start time indication information of a rate control time unit used for rate control, and the start time indication information indicates a start time of the rate control time unit.

Abstract: Embodiments of this application provide a communication method and apparatus, and a device. The method includes: A network device determines first user slice information of a first user. The network device sends the first user slice information to a terminal device, where the terminal device is a terminal device used by the first user, and a user slice indicated by the first user slice information is a user slice used by the first user. This improves flexibility of performing communication by using a network slice.
