Mobile edge platform switching method, apparatus, and system

A mobile edge platform switching method, comprising:

• obtaining, by a first mobile edge platform, an uplink data packet of a user equipment;
• and
• when the uplink data packet is forwarded by a second mobile edge platform:
• obtaining, by the first mobile edge platform, information about the user equipment from the uplink data packet;
• determining, by the first mobile edge platform and based on the information about the user equipment, current service quality of a service provided by a source application instance for the user equipment;
• and
• when the current service quality does not meet a service quality requirement of the user equipment, determining, by the first mobile edge platform, that the user equipment needs to perform mobile edge platform switching;
• determining, by the first mobile edge platform, an application identity of the source application instance of the user equipment, wherein the first mobile edge platform provides the service for the source application instance, and wherein the source application instance provides the service for the user equipment;
• and
• sending, by the first mobile edge platform, the application identity to the second mobile edge platform comprises:
• sending, by the first mobile edge platform, a switching request message to the second mobile edge platform, wherein the switching request message carries the application identity, wherein the application identity is used by the second mobile edge platform to determine a target application instance of the user equipment, wherein the source application instance and the target application instance are two different copies of a same application and are deployed on two different virtual machines, wherein the source application instance and the target application instance have the same application identity uniquely identifying the application, and wherein the second mobile edge platform provides the service for the target application instance.

• receiving, by a target application instance, a switching notification message from the mobile edge platform, wherein the switching notification message is used to instruct the target application instance to provide the service for the user equipment, and the mobile edge platform provides the service for the target application instance;
• and
• sending, by the target application instance, a synchronization request message to the source application instance based on the switching notification message, wherein the synchronization request message is used to request the source application instance to send context information of the user equipment to the target application instance, wherein the source application instance and the target application instance are two different copies of a same application and are deployed on two different virtual machines, and wherein the source application instance and the target application instance have the same application identity uniquely identifying the application.
