PURPOSE: A location server, a communication system comprising the same and a communication method thereof are provided to increase the efficiency of the communication system without the interworking with an external circuit network for a newly added switching center. CONSTITUTION: A communication system includes an originating-side switching center(30) and a location server(20). The originating-side switching center processes the reception of an outgoing call. The location server stores information about a switching center in which the destination number of the outgoing call is stored, and then provides information about destination-side switching center to the originating-side switching center in response to the request of the originating-side switching center. The originating-side switching center transmits the outgoing call to a subscriber terminal corresponding to the destination number when the originating-side switching center information is the same as the destination-side switching center information. |
