Set it to the disabled state. The availability status information is information indicating whether wired / wireless integrated service is available. The access manager unit 150 transmits the available status information to the control unit 140, and the control unit 140 sets VoIP to be impossible through Wi-Fi, so that the call can be made through the WCDMA network. 100). In addition, the connection manager unit 150 may display a message indicating the impossible state of the wired / wireless integrated service together with the setting of the available state information. For example, the connection manager 150 may display a message “No FMC service is currently available” through the display unit 111. At this time, it is obvious that the control unit 140 may control the message display according to the implementation method of the mobile terminal 100.

When the base station apparatus 290 to which the mobile terminal 100 is connected may provide the wired / wireless integrated service, in step 230, the connection manager 150 may determine the available state information of the wired / wireless integrated service of the mobile terminal 110. Set to. The access manager unit 150 transmits the available status information to the controller 140, and the controller 140 sets VoIP to be enabled through Wi-Fi, so that the call can be made through the Wi-Fi network.
