ABSTRACT:
A portable terminal includes a first store for storing a first physical address including a serial number of the terminal, a second store for storing a first logical address including a subscriber's telephone number, a third store for storing a second physical address of a hardware used for computer communication, a fourth store for storing a second logical address corresponding to the second physical address, an interface for radio LAN, and an interface for PHS system. When a call is originated, a first channel is connected by using the first physical address and the first logical address. The second physical address and the second logical address are transmitted to the network from the call originator's terminal through the first channel, thereby setting in a state enabling communication between computers, and necessary data is transmitted to the call originator's terminal through a second channel by communication between computers.
