Abstract:
1. A User Equipment (UE) in a mobile communication system that comprises a Packet data Gateway (PGW) and the UE, the UE comprising: a control circuit configured to establish a first transfer path by way of a first access network between the UE and the PGW, wherein when performing transmission/reception of a plurality of flows with the PGW by using the first transfer path, the control circuit is configured to establish a default EPS (Evolved Packet System) bearer as a second transfer path by way of a second access network between the UE and the PGW by transmitting an attach request for starting an attach procedure; and the control circuit configured to establish a specific EPS bearer as a third transfer path by way of the second access network between the UE and the PGW after transmitting a notice including identification information that identifies a specific flow among the plurality of flows, to the PGW by way of the second access network; wherein the control circuit is configured to switch a transfer path for performing transmission/reception of the specific flow to the third transfer path by way of the second access network.
