Abstract
Provided is a method for selecting a shunt gateway and a controller. The method includes that: the controller allocates an Anycast address of Serving Gateways (S-GWs) for a user equipment, and sends the Anycast address to all of the S-GWs; the controller sends the Anycast address to a radio-side network element via a Mobility Management Entity (MME); and when the controller receives a Packet_In message and a first uplink data packet from the user equipment sent by an S-GW, the controller selects the S-GW as an S-GW for the user equipment.
