Classification: CPC H | IPC G  H

Claim 14:
15. A communication apparatus, comprising a processor, a memory, and instructions that are stored in the memory and that can be run on the processor, wherein the instructions, when running, cause the apparatus to perform a method comprising:
obtaining information about a source application instance of an application accessed by a terminal device and information about a target application instance of the application; and
sending a first message to a first multi-access edge computing (MEC) platform, wherein the first message is used to request to migrate a user context of the application from the source application instance to the target application instance, the source application instance is deployed on the first MEC platform, and the target application instance is deployed on a second MEC platform;
receiving a second message from the first MEC platform, wherein the second message indicates a migration state of the user context of the application;
receiving, by the MEC network element, a third message from a core network control plane network element, wherein the third message is used to notify that a user plane path of the terminal device has changed; and
determining, by the MEC network element, the information about the source application instance and the information about the target application instance based on the third message, wherein the source application instance is located at a location corresponding to an access identifier of a source data network, and the target application instance is located at a location corresponding to an access identifier of a target data network.
