Routing system in the next generation open network and method of controlling the routing system

摘要

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.
