<p>For data transfer to and from a host device via a radiocommunication network, and to and from a communication device connected to an external communication network outside the radiocommunication network via the radiocommunication network, communication setting information on the external communication network, internally stored, is used to set a relation of connection to the external communication network via the communication device (S1-1 to S11). The relation of connection with the external communication network is used to transfer data to and from the external communication network via the communication device and also transfer data to and from the host device via the radiocommunication network, thereby controlling data transfer between the host device and external communication network (S12 to S14). <IMAGE></p> |
