Abstract
Since user data from a mobile station always passes a gateway, even in communication between mobile stations in a cell of the same base station in the same mobile station system, user data is transferred to the gateway and the trombone phenomenon occurs. Traffic is concentrated in the gateway and networks near the gateway. A local routing node includes a unit for passing signaling of communication between a base station and the gateway according to a protocol of the mobile communication system, for extracting and decapsulating bearer data transferred between the base station and the gateway, and for thereby obtaining and transferring user data and a unit for encapsulating and transferring user data. The local routing node extracts bearer data, which is conventionally transferred up to the gateway, and transfers the data to the network.
