Function migration method and apparatus

A method implemented by a second device and comprising:

• receiving, from a first device, a first request carrying a first identifier of the first device, a second identifier of a first application of the first device, and a third identifier of a second application of the second device;
• creating a first group, wherein first members of the first group comprise the second application;
• sending, to the first device, a first response indicating the first group;
• receiving, from the first device, a second request requesting to add the first application to the first group;
• and
• receiving a first function that is in the first application and that is migrated by the first device,
• wherein the first function comprises one or more graphical user interfaces (GUIs).

A first device comprising:

• a memory configured to store program instructions;
• one or more processors coupled to the memory and configured to execute the program instructions to cause the first device to:
• send, to a second device, a first request carrying a first identifier of the first device, a second identifier of a first application of the first device, and a third identifier of a second application of the second device;
• receive, from the second device, a first response indicating a first group created by the second device, wherein first members of the first group comprise the second application;
• send, to the second device, a second request requesting to add the first application to the first group;
• and
• migrate a first function in the first application to the second application,
• wherein the first function comprises one or more graphical user interfaces (GUIs).
