MOBILE COMMUNICATION SYSTEM, QoS CONTROL STATION AND MOBILE STATION

摘要

A first access network in which a bearer transfer path that guarantees a predetermined QoS has been established and a second access network in which a transfer path which is different from that in the first access network has been established are provided, and PCRF 60 transmits to a mobile station an uplink traffic switching request including information of a flow of which the access system type is switched, out of flows in which a UE 10 performs communication, and information of an access system type to be a switching destination of the flow, and the UE 10, upon receiving the uplink traffic switching request, switches a transfer path of the flow included in the uplink traffic switching request to that of the access system type. This makes it possible to provide a mobile communication system or the like in which a transmission path of a flow established by a mobile station capable of being simultaneously connected to a plurality of radio access networks is able to be switched without making alterations to all the radio access networks, with initiative taken by a control station installed in a core network.

主权项

1. A mobile station apparatus comprising:
a control portion; and a transmission/reception portion, wherein the control portion is configured to:
establish a first communication path connecting with a core network via a first access network based on an Access Point Name (APN), andestablish a second communication path connecting with the core network via a second access network based on the APN, and the transmission/reception portion is configured to:
transmit or receive a first flow and a second flow by using the first communication path,receive, from the core network, a switching request containing at least an identification information of the first flow and information indicating a switch to the second access network,transmit or receive the first flow by switching to use the second communication path, based on a reception of the switching request, andmaintain transmission or reception of the second flow by using the first communication path.
