MOBILE RADIO DATA COMMUNICATION SYSTEM

摘要

In a mobile radio data communication system in which a wireless circuit switching network system composed of a mobile radio station (30a), a radio connecting device (20a), and an exchange (10a) is connected to a LAN (40a) through a TA (60a) and a router (50a) so that users of the system can transmit packet data to a desired communication party in a virtual network extending over the wireless circuit switching network system and a LAN without being bothered with the conversion of the address of a physical network to an address; the exchange (10a) performs the address conversion which is required for establishing a communication channel between terminals in the system based on a conversion table.
