Abstract
Abstract In order for the user to perform a transmission of packet data to a desired communication counterpart on a virtual network across a wireless circuit exchange type network system and a LAN without being bothered by address exchange between an address of a physical network and an address of a virtual network, an exchange (10a) performs an address exchange necessary for establishing a communication channel between the terminal equipments within the system using a conversion table, in a mobile wireless data communication system in which a wireless circuit type network system comprising a wireless mobile station (30a), a wireless connection equipment (20a) and the exchange (10a) is connected to a LAN (40a) through a TA (60a) and a router (50a).
