Routing system in the next generation open network and method of controlling the routing system
First Claim
1. A method of controlling a routing system in the next generation open network that includes a number of media gateway controllers that support cooperation of packet network and public switched telephone network (PSTN), comprising:
- transmitting bearer information from an originating media gateway to an originating media gateway controller;
receiving call request signal from the originating media gateway controller; and
transmitting the call request signal to a terminating media gateway controller.

Abstract
The present invention relates to a routing system in the next generation open network and a method of controlling the routing system. More particularly, the present invention relates to mutual communication between media gateway controllers that use different protocols. A method of controlling a routing system in the next generation open network according to one preferred embodiment of the present invention stores information of a number of media gateway controllers that support cooperation of packet network and public switched telephone network (PSTN) in advance and performs routing of call by retrieving a terminating media gateway controller when call request signal is received from an originating media gateway controller. Further, the method of controlling a routing system in the next generation open network supports routing of call between media gateway controllers using different protocols.

17. A method of controlling a routing system in the next generation open network, comprising:
-
storing in advance in a routing server communication set-up information of a number of media gateway controllers that support cooperation of packet network and PSTN;
extracting IP address of the rouging server by translating call request signal that originating media gateway controller received from originating PSTN and transmitting the call request signal to the routing server;
extracting IP address of terminating media gateway controller by translating call request signal that the routing server received from the originating media gateway controller and transmitting the call request signal to the terminating media gateway controller; and
retrieving a terminating PSTN by translating the call request signal that the terminating media gateway controller received from the routing server and transmitting the call request signal to the terminating PSTN. - View Dependent Claims (18, 19, 20, 21, 22)

23. A routing system in the next generation open network, comprising:
-
originating media gateway controllers configured to transmit call request signal received from an originating PSTN;
terminating media gateway controllers configured to retrieve a terminating PSTN by translating the call request signal and to transmit the call request signal to the terminating PSTN; and
routing servers configured to have communication set-up information of a number of media gateway controllers, to receive the call request signal from the originating media gateway controller and to transmit the call request signal to the terminating media gateway controller corresponding to the call request signal. - View Dependent Claims (24, 25, 26)
