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: This application provides a context transfer method and a communication apparatus. The method includes: When an edge enabler client context fails to be relocated from a second edge enabler server to a first edge enabler server, a first apparatus sends first information to a first edge application server corresponding to the first edge enabler server, where the first information is used by the first edge application server to subscribe to edge enabler server capability exposure information from the first edge enabler server. In the foregoing technical solution, when an edge enabler client context fails to be transferred, the first apparatus may indicate a target edge application server to subscribe to edge enabler server capability exposure information from a target edge enabler server.

Abstract: Embodiments of this application relate to the field of communication technologies, and provide a method for determining an edge configuration server and an apparatus, to select a more proper edge configuration server for a terminal apparatus. The method includes: A core network element determines, based on a mobile network accessed by a terminal apparatus, that an edge configuration server serving the terminal apparatus is a first edge configuration server, where at least one mobile network corresponding to the first edge configuration server includes the mobile network accessed by the terminal apparatus. The core network element sends, to the terminal apparatus, information indicating the first edge configuration server.

Abstract: An application context relocation method and apparatus are provided. One example method includes: receiving first information from an application function entity, where the first information is for indicating to relocate an application context associated with the application function entity; and when an event that triggers relocation of the application context occurs, determining, based on the first information, to relocate the application context.
