Wireless Communication System

A wireless communication system capable of establishing connection of basic access network capable of signaling communication concerned with continuous communication switch control and access network for carrying out other data communication than the signaling communication, at the same time, using at least two or more kinds of communication networks including wireless communication network, the wireless communication system including wireless communication terminal, basic access network terminal and network server,

• wherein the wireless communication terminal includes:
• access communication processing unit capable of communication with at least two or more kinds of communication networks including the wireless communication network;
• each network device corresponding to each communication network;
• a passage and device for communication with the basic access network terminal;
• and basic access network client processing unit having client function in signaling communication concerning connection/disconnection processing request to at least the access network obtained through the communication passage,
• the network server includes:
• management information database having user information and device information concerning the basic access network terminal;
• and basic access network server processing unit which controls the signaling communication concerning communication control containing registration/updating processing of at least the basic access network terminal with the basic access network terminal when switching communication of the access network continuously, and
• the basic access network terminal includes basic access network signaling processing unit which carries out the signaling communication with the basic access network server processing unit of the network server and the basic access network client processing unit at the wireless communication terminal and device control unit which at least controls the communication device.
