MOBILE COMMUNICATION SYSTEM, SECOND BASE STATION, MOBILE STATION, AND COMMUNICATION METHOD FOR MOBILE COMMUNICATION SYSTEM

摘要

Provided is a mobile communication system in which a first base station included in a first access network initiatively performs a handover from the first base station to a second base station, with respect to communication including a plurality of flows, the second base station determines an availability of a handover for each flow, and notifies the mobile station of the determination result, and the mobile station switches communication of a flow for which the handover is determined to be possible, from a transfer path over the second access network to a transfer path over the first access network. Thus, in the handover of the mobile station between access systems, the handover is initiatively performed by a base station, a handover destination access system determines a communication flow to be handed over and a communication flow to be handed over, and the access networks are switched based on the determination result, so as to continue communication.

主权项

1. A mobile communication system in which a first access network and a second access network are connected to a core network, and a first base station included in the first access network initiatively performs a handover of a mobile station connected to the first base station, from the first base station to a second base station included in the second access network, with respect to communication including a plurality of flows,
wherein the mobile station establishes a transfer path through a control station included in the core network and the first access network, wherein the second base station determines the availability of a handover for each flow, and notifies the mobile station of the determined availability of handover, and wherein the mobile station establishes a transfer path over the second access network and switches communication of a flow for which the handover is determined to be possible, from a transfer path over the first access network.
