Communication method and corresponding apparatus

An apparatus, comprising:

• at least one processor;
• and
• one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to:
• send a first request to a target network apparatus, wherein the first request is for requesting to set up a first communication interface between the access network apparatus and the target network apparatus;
• receive a first response from the target network apparatus, wherein the first response indicates that the target network apparatus has configured a context parameter of the first communication interface;
• set up the first communication interface with the target network apparatus based on the context parameter of the first communication interface;
• and
• switch a corresponding communication interface from a second communication interface to the first communication interface, wherein the second communication interface is a communication interface between the access network apparatus and a source network apparatus.
