Abstract
A communication network comprising a plurality of border controllers, a first packet voice network, a second packet voice network coupled to the first packet network by the plurality of border controllers, and a master border controller coupled to the plurality of border controllers and coupled to the first packet voice network and the second packet voice network. The master border controller, responsive to receiving a plurality of update messages from the plurality of border controllers, processes the update messages to determine the operational states of the plurality of border controllers.
Claims38
A communication network comprising:
- a plurality of border controllers;
- a first packet voice network;
- a second packet voice network coupled to the first packet voice network by the plurality of border controllers;
- and
- a master border controller coupled to the plurality of border controllers and coupled to the first packet voice network and the second packet voice network;
- wherein the master border controller, in response to receiving a plurality of update messages from the plurality of border controllers, processes the update messages to determine operational states of the plurality of border controllers, and responsive to receiving a query from a first switch in the first packet voice network for a call between the first and second packet voice networks, processes the query to determine a first border controller for the call of the plurality of border controllers based on the operational states of the plurality of border controllers, and transfers a response to the first switch in the first packet network wherein the response indicates the first border controller.
A method of operating a communication network comprising a plurality of border controllers, a first packet voice network, a second packet voice network coupled to the first voice packet network by the plurality of border controllers, and a master border controller coupled to the plurality of border controllers and coupled to the first packet voice network and the second packet voice network, the method comprising:
- receiving in the master border controller a plurality of update messages from the plurality of border controllers, and in response
- processing in the master border controller the update messages to determine operational states of the plurality of border controllers;
- and
- responsive to receiving a query in the master border controller from a first switch in the first packet voice network for a call between the first and second packet voice networks, processing the query to determine a first border controller for the call of the plurality of border controllers based on the operational states of the plurality of border controllers, and transferring a response to the first switch in the first packet network wherein the response indicates the first border controller.
