Mobile communication system, QoS control station and mobile station
First Claim
1. A mobile station apparatus comprising:
- a control portion; and
a transmission/reception portion, whereinthe 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, andthe 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 control message containing at least an identification information of the first flow,send, to the core network, a response control message for the control message,after transmission of the response control message, transmit or receive the first flow by switching to use of the second communication path based on the control message, andmaintain transmission or reception of the second flow by using the first communication path,wherein the control message is the message received in a procedure initiated by the core network, the procedure being to change the communication path for the first flow.

Abstract
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.

5. A gateway apparatus being configured in a core network and connecting a Packet Data Network (PDN) with the core network, the gateway apparatus comprising:
a transmission/reception portion configured to; transmit/receive a first flow and a second flow by using a first communication path connecting a mobile station apparatus and a core network via a first access network, the first communication path being established based on an Access Point Name (APN), transmit, toward the mobile station via a second gateway, a control message containing at least an identification information of the first flow in order to switch communications of the first flow to use a second communication path connecting the mobile station apparatus and the core network via a second access network, the second communication path being established based on the APN, the second gateway being connecting the core network and the second access network, receive, from the mobile station, a response control message for the control message, and after reception of the response control message, transmit or receive the first flow by switching to use of the second communication path based on the control message, wherein the control message is the message transmitted in a procedure initiated by the core network, the procedure being to change the communication path for the first flow. - View Dependent Claims (6, 7, 8, 9)

10. A communication method in a mobile station apparatus, the communication method comprising:
-
establishing a first communication path connecting with a core network via a first access network, based on an Access Point Name (APN), establishing a second communication path connecting with the core network via a second access network, based on the APN, transmitting or receiving a first flow and a second flow by using the first communication path, receiving, from the core network, a control message containing at least an identification information of the first flow, sending, to the core network, a response control message for the control message, after transmission of the response control message, transmitting or receiving the first flow by switching to use the second communication path based on the control message, and maintaining transmission or reception of the second flow by using the first communication path, wherein the control message is the message received in a procedure initiated by the core network, the procedure being to change the communication path for the first flow.
