MOBILE COMMUNICATION TERMINAL, COMMUNICATION DEVICE, MOBILE COMMUNICATION METHOD AND COMMUNICATION METHOD

PROBLEM TO BE SOLVED: To allow PPP (point-to-point protocol)-based communication to be continued appropriately, even in a communication environment which varies continuously with a terminal that moves. SOLUTION: A communication terminal 10 includes a plurality of wireless access means 11, 12 and 13 for establishing wireless communication according to PPP communication links, which each differing in communication method thereof, with a fixed communication device 20, the other end in communication; a PPP device 14 for integrating the established communication links; and an effective wireless LAN search unit 16 for detecting whether the wireless LAN adaptor 12 is capable of wireless communication. The PPP device 14 controls the wireless LAN adaptor 12, which is detected to be capable of wireless communication and an L2TP virtual device 13, such that they establish a communication link.
