NETWORK SWITCHING METHOD, ACCESS POINT, CONTROLLER AND BASE STATION

摘要

Provided in an embodiment of the present invention are a network switching method, access point, controller and base station, the network switching method comprising: a first network access point acquires transmission delay reference information from a user equipment (UE) to be switched to a second network access point, the transmission delay reference information being used to determine transmission delay information between the UE to be switched to the second network access point; and the first network access point transmits to a second network controller a switching request containing the transmission delay reference information, the switching request being used to instruct the second network controller to transmit the transmission delay information to the second network access point, and to control the second network access point to conduct network switching synchronization with the UE to be switched. The embodiment of the present invention improves network switching efficiency, and solves the problem of long network interruption delay during network switching for a UE.
