ABSTRACT:
A mobile telephone location system is provided wherein a plurality of mobile telephone exchanges, each of which controls an area and is in a position to monitor the presence of mobile telephone units within its own area, are connected with a national center. The national center is capable of receiving requests for the location of mobile telephone units from each of the mobile telephone exchanges and transmit location information via satellite to all of the mobile telephone exchanges within the system. The mobile telephone exchange in whose area the paged mobile telephone unit is located sends location information to the national center or directly to the originating mobile telephone exchange. This location information contains information pertaining to the identity of the mobile telephone exchange and the mobile telephone. This data is transmitted by the national center to the mobile telephone exchange which issued the request enabling the exchange to make the connection.
