Provided in the present invention is a method for establishing an interface, said method comprising: a service node sends a first indication message to an anchor node, the first indication message being used for indicating the establishment of a first interface between the service node and the anchor node (S201), and the service node receives a response message sent by the anchor node in response to the first indication message (S202); or the service node receives a first indication node sent by the anchor node, the first indication message being used for indicating the establishment of the first interface, and the service node sends a response message to the anchor node in response to the first indication message. The present invention allows the wireless connection of a terminal and the service node to terminate at the anchor node; when the terminal switches service node under the same anchor node, the interface of the terminal need not be switched, thus reducing the core network signalling load caused by switching. |
