Abstract: This application provides a method for sending application context relocation ACR information and an apparatus. The method includes: An edge application server EAS receives first information from an edge enabler server EES, where the first information indicates whether ACR information is allowed to be sent by using an enabler layer. The EAS determines, based on at least the first information, a manner of sending the ACR information. The EAS sends the ACR information in the manner of sending the ACR information. According to the solution of this application, the manner of sending the ACR information by the EAS is associated with whether an EEC subscribes to the ACR information. Therefore, according to the method provided in this application, the EAS can send the ACR information in a correct manner, to ensure that the ACR information can be successfully sent to a terminal device.

Abstract: A method includes obtaining at least one of application context relocation (ACR) capability information supported by an edge application server (EAS), ACR capability information supported by an edge enabler client (EEC), ACR capability information supported by an application client (AC), or ACR capability information supported by an edge enabler server (EES). The method also includes selecting ACR mode information for the AC based on the at least one of the ACR capability information supported by the EAS, the ACR capability information supported by the EEC, the ACR capability information supported by the AC, or the ACR capability information supported by the EES. The ACR mode information indicates an identifier indicating the AC and an ACR scenario selected for the AC.

Abstract: An aircraft control method and an apparatus are provided, and pertain to the field of communications technologies. The method performed by an AMF network element includes: obtaining information about a no-fly zone of an aircraft (301); sending reference information to a control apparatus when a shortest distance between the aircraft and the no-fly zone is less than or equal to a first preset value (302), where the reference information includes at least one of first indication information and location information of the aircraft, and the first indication information indicates that the shortest distance between the aircraft and the no-fly zone is less than or equal to the first preset value. This resolves problems that efficiency of preventing an aircraft from flying in a no-fly zone is relatively low and an advance preparation process is relatively complex and time-consuming, avoids installation of geofences on an edge of the no-fly zone.

Abstract: A data transmission method and apparatus are described. The method includes sending, by a terminal, a first request message to an SMF, where the first request message is used to request to perform a UPF local broadcast breakout on unicast flow data; and receiving, by the terminal, a response message for the first request message. The first request message is used to request to perform the UPF local broadcast breakout on the unicast flow data, so that a UPF that manages a broadcast session does not forward the received unicast flow data to an AS, but directly performs the broadcast breakout on the received unicast flow data locally. Therefore, a length of a transmission path for the unicast flow data is reduced, and a transmission delay of the unicast flow data that needs to be broadcast in a small range is reduced.

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, to hide, from an API invoker, an API exposing function (AEF) that provides an API. The method includes: receiving, by a common API framework core function (CCF) from a topology hiding request entity, a request message that includes information about an API and that is used to request to hide an AEF that provides the API; determining, based on the request message, a topology hiding entry point used by an API invoker to invoke the API; and sending, to the topology hiding entry point, an identifier of the API and an identifier of the AEF that provides the API, so that the topology hiding entry point hides the AEF that provides the API.
