ABSTRACT:
An object of the present invention is to make it possible to appropriately maintain PPP-based communications even in an environment in which the terminal moves and the communication environment continually changes. A mobile communication terminal comprises a plurality of wireless accessing devices for establishing PPP-based communication links for respectively different modes of wireless communications with a fixed communication apparatus, which is a communication partner; a PPP device for combining the established communication links; and a valid wireless LAN searching portion for detecting that wireless communication is possible for a wireless LAN adapter. The PPP device executes control so as to establish communication links for the wireless LAN adapter detected as being capable of wireless communication, and for a L2TP virtual device.
