<p>PROBLEM TO BE SOLVED: To conduct connection type data communication between a mobile data terminal and a stationary data terminal connecting to a LAN in a radio communication system such as a digital cordless telephone system. SOLUTION: In the case that a destination address of a packet is not registered, a base station controller 2b receiving a packet from a stationary data terminal 12b or a mobile data terminal 5b allows a base station controller 2a managing a home network 10a of a concerned mobile data terminal 5a through a signal line 9 for telephone communication to inquire about an address allocated to a radio network 10c of a mobile destination to retrieve an identifier in a data communication network of the mobile destination, and encapsulates the packet by setting the identifier to be a destination address and sends the resulting packet to the data communication network. Furthermore, a base station controller 2c of the mobile destination receiving the packet from the data communication network routes the packet to the destination mobile data terminal 5a based on the destination address of the packet.</p> |
