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: This application discloses a deterministic transmission method, a communication apparatus, and a storage medium, and relates to the communication field. In the method, a radio access network device may generate deterministic transmission capability information of a first switching node, and send the deterministic transmission capability information to a first network element. The first switching node includes the radio access network device and a terminal. Then, the radio access network device may receive a first scheduling policy that is delivered by the first network element based on the deterministic transmission capability information of the first switching node, so that deterministic transmission can be performed according to the first scheduling policy. This reduces a delay variation of a QoS flow carrying a TSN flow in a 5GS, and can avoid a need to select a QoS flow whose delay indicator is excessively high for the TSN flow.

Abstract: This application provides a communication method and apparatus, to improve data transmission efficiency. The communication method and apparatus may be used in systems such as a 5G system and a V2X system. The method includes: After receiving, through a first unicast session, a request message for adding a first terminal to a multicast group, a first session management network element sends second information based on first information. The second information is for requesting a first user plane network element to send multicast data not through the first unicast session or not to send first signaling to a data network. The first signaling is for establishing a second tunnel used by the data network to send the multicast data to the first user plane network element, and the first user plane network element is a user plane network element corresponding to the first unicast session.

Abstract: This application discloses a communications method and apparatus, to resolve a problem that a terminal device can still receive downlink LADN data when moving out of an LADN SA. The method includes: receiving, by a RAN node, a first message from an AMF node, where the first message includes specified area related information of a terminal device, and the specified area related information is used to indicate a specified area of the terminal device; and when the RAN node determines, based on the specified area related information and first location information of the terminal device, that the terminal device moves out of the specified area, sending, by the RAN node, the first location information or first indication information to the AMF node or an SMF node, where the first indication information is used to indicate that the terminal device already moves out of the specified area.

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.
