Switching system connecting a radio communication terminal via a LAN line to a public switched network or a leased line
First Claim
1. A switching system having a LAN (Local Area Network) line connectable to a radio communication terminal, which effects radio communication to either one of a public switched network line and a leased network line, for executing call switching, comprising:
- a telephone switching system accommodating the public switched network line and the LAN line for executing the call switching; and
a terminal adapter for effecting communication to the LAN line when directly connecting the radio communication terminal, said terminal adapter delivering, while connecting said radio communication terminal, being supplied with electric power from said radio communication terminal and then detecting the connection of the radio communication terminal, number conversion information including terminal information stored in the radio communication terminal and an identification number assigned to said terminal adapter to said telephone switching system, and effecting communication on the LAN line between the radio communication terminal and said telephone switching system;
said terminal adapter comprising;
a voice controller for executing voice control on a basis of control information for a voice processing system, which is received from the radio communication terminal, to hold voice communication on the LAN line between the radio communication terminal and said telephone switching system;
said telephone switching system comprising;
a position information manager for registering, on receiving the number conversion information from said terminal adapter over the LAN line, the identification number of said terminal adapter and the terminal information of the radio communication terminal included in said number conversion information in one-to-one correspondence for thereby managing position information of the radio communication terminal connected to said terminal adapter; and
a switching controller for searching, on receiving a call originated on either one of a telephone terminal accommodated in said switching system and an accommodated communication terminal having a voice communication function and interconnected to the LAN line, said position information manager for the terminal information in accordance with a destination number and substituting, if the terminal information matching with the destination number is present in said position information manager, the identification number of said terminal adapter matching with the terminal information for the destination number to thereby control call switching.

Abstract
A telephone switching system includes a position information management database and a call conversion controller. On receiving number conversion information from an adapter having a radio communication terminal connected, the database registers an identification number assigned to the adapter and terminal information particular to the communication terminal in one-to-one correspondence, thereby managing the position of the communication terminal. When a call is originated on a telephone terminal interconnected thereto or a communication terminal having a voice communication function interconnected to its LAN system, the call conversion controller searches the database on the basis of a destination number and substitutes, if terminal information corresponding to the destination number is found out in the database, the identification number of the adapter corresponding to the terminal information for the destination number to process call switching.
