    Abstract: This application discloses a communication method, an apparatus, and a device, to ensure continuity of service transmission. The method includes: An AS sends a service data packet of a first service to a terminal device over a multicast session. When a condition for the terminal device to perform inter-communication system switching is met or the terminal device performs the inter-communication system switching, the terminal device may send first information to trigger the AS to send the service data packet of the first service to the terminal device in a unicast transmission mode. In this way, an inter-communication system switching procedure of the terminal device does not affect transmission of the first service of the terminal device, to ensure continuity of service transmission.

    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.

    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 a communication method and an apparatus. The method includes: A terminal device, a serving access network device, a target access network device, a mobility management network element, or a session management network element corresponding to the terminal device, or a session management network element corresponding to a broadcast service may bind the terminal device to the broadcast service and/or activate/deactivate the broadcast service, based on one or more of identification information of the broadcast service, a service area of the broadcast service, a location of the terminal device, or a status of the terminal device, to reuse a unicast resource of the terminal device. In addition, a binding procedure and an activation procedure may be coupled or separately performed.

    Abstract: A data transmission method and apparatus, a system, and a storage medium are provided. In the method, a user plane function network element performs transmission through an established unicast user plane connection, and when sending data of a first service to an access network device, the user plane function network element can be configured to send only the data that is of the first service and that is carried in one data flow to improve use efficiency of resources on a core network side. Then, the access network device can send, in a multicast manner through an established unicast channel, the received data of the first service to a group of terminals corresponding to the data of the first service, and does not need to additionally establish a multicast channel and switch to the multicast channel, thereby further reducing data transmission delay.

    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.
