Abstract: A handover method and a communication apparatus are provided. The method includes: A target access network device obtains a first message and information used for transmitting multicast data, where the first message is used for requesting to establish a resource for handing over a terminal device to the target access network device. The target access network device sends a second message, where the second message indicates the established resource on the target access network device; receives a first packet from a user plane network element, where the first packet corresponds to the information used for transmitting the multicast data; and sends the first packet to the terminal device. In this way, the terminal device is handed over from a source access network device to the target access network device when the terminal device receives the multicast data.

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.

Abstract: This application provides an unmanned aerial vehicle authentication method and an apparatus. The method includes: sending, by a communications device after determining that a type of a terminal is a UAV, authentication information of the terminal to an authentication server, so that the authentication server can perform authentication on the terminal based on the authentication information of the terminal, and therefore, the authentication server completes authentication on the terminal. In addition, the unmanned aerial vehicle is allowed to fly only after authentication on the terminal succeeds. Therefore, flight security of the unmanned aerial vehicle can be improved.

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.
