Abstract
A mobile station that establishes a first transfer path by way of a first access network between the mobile station and a control station. The mobile station establishes a default EPS (Evolved Packet System) bearer by way of a second access network between the mobile station and the control station by transmitting an attach request for requesting a handover of a partial flow among the plurality of flows when performing transmission/reception of a plurality of flows with the control station by using the first transfer path.
Claims4
A User Equipment (UE) comprising:
- transmission and/or reception circuitry;
- and
- control circuitry,
- wherein
- the control circuitry is configured to establish, by way of a first access network, a first transfer path between the UE and a Packet Data Network Gateway (PGW),
- the transmission and/or reception circuitry is configured to perform communication of a plurality of flows with the PGW by using the first transfer path,
- the control circuitry is further configured to establish, by way of a second access network, a default Evolved Packet System (EPS) bearer between the UE and the PGW by the transmission of an attach request during the communication,
- the control circuitry is further configured to establish, by way of the second access network, a dedicated EPS bearer between the UE and the PGW,
- the control circuitry is further configured to switch a specific flow among the plurality of flows from the first transfer path to the dedicated EPS bearer,
- the transmission and/or reception circuitry is further configured to perform communication of the specific flow by using the dedicated EPS bearer, and
- the transmission and/or reception circuitry is further configured to perform communication of the remaining flows except the specific flow among the plurality of flows by using the first transfer path.
