Abstract

A radio terminal performs traffic steering between a mobile communication network and a wireless LAN. The radio terminal receives dedicated parameters notified individually from a cell provided in the mobile communication network. The dedicated parameters being determination parameters for determining whether or not to perform the traffic steering. The radio terminal discards the dedicated parameters when performing a connection process on the cell for transition to a Radio Resource Control (RRC) connected state after transition to an RRC idle state on the cell.

Claims

1. A radio terminal that performs traffic steering between a mobile communication network and a wireless LAN, comprising:

a receiver configured to receive dedicated parameters notified individually from a cell provided in the mobile communication network, the dedicated parameters being determination parameters for determining whether or not to perform the traffic steering; and

a controller configured to discard the dedicated parameters when performing a connection process on the cell for transition to a Radio Resource Control (RRC) connected state after transition to an RRC idle state on the cell.

2. The radio terminal according to claim 1, wherein

the controller holds the dedicated parameters in a period during which a predetermined timer started in response to the transition to the RRC idle state is running, and

the controller stops the predetermined timer when performing the connection process after transition to the RRC idle state.

3. The radio terminal according to claim 2, wherein

the controller stops the predetermined timer when performing the connection process due to quality deterioration of the wireless LAN after transition to the RRC idle state.

4. The radio terminal according to claim 2, wherein

the controller discards the dedicated parameters along with the stopping of the timer.

5. A processor for controlling a radio terminal that performs traffic steering between a mobile communication network and a wireless LAN, comprising:

a controller coupled to a memory, the controller configured to execute the processes of;

receiving, dedicated parameters notified individually from a cell provided in the mobile communication network, the dedicated parameters being determination parameters for determining whether or not to perform the traffic steering; and

discarding the dedicated parameters when performing a connection process on the cell for transition to a Radio Resource Control (RRC) connected state after transition to an RRC idle state on the cell.
