Title:

CONTROL STATION, MOBILE STATION, MOBILE COMMUNICATION SYSTEM AND MOBILE COMMUNICATION METHOD

Document Type and Number:

WIPO Patent Application WO/2010/053066

Kind Code:

A1

Abstract:

When performing handover from an access network (B) to an access network (A), a UE (10) transmits an attach request to an MME (30). The MME (30) establishes a bearer in a first access network based on the attach request. The UE (10) requests that the MME (30) establish a specific bearer to guarantee the QoS necessary for flow. The MME (30) receives the request for establishment of a specific bearer, establishes a specific bearer to guarantee the QoS for flow and establishes a path for communication flow between the UE (10) and a PGW (20). This provides a mobile communication system that can accomplish handover while maintaining communication quality when handover is performed by the mobile station selecting a specific flow from among multiple flows and handing over directly to the bearer communication path.
