Estimating the term…
Call Control entities in a network communicate between themselves by amending call processing messages to include encrypted network information. As such, a call may be established whose path through the network is dependent on the paths of other calls. Information of a scope larger than a Call Controller normally possesses can, as a result of this communication, be made available to Call Controllers for constraining call establishment. This information could relate to other calls and connections associated with those other calls. The information may also relate to gateways in and to adjacent networks and the Call Controllers in the adjacent networks that are related to the current Call Controller.
In a connection-oriented network including a plurality of interconnected call controllers, a method of optimally establishing multiple calls between a source client call controller and a destination client call controller comprising:
In a connection-oriented network including a plurality of interconnected call controllers, a call controller comprising:
In a connection-oriented network including a plurality of interconnected call controllers, a call controller comprising:
A method of, at a client call controller, requesting the establishment of a second call from a source to a destination, where a path for said second call uses path segments distinct from path segments used in a previously determined path for a first call, said method comprising, responsive to receiving a call processing message, where said call processing message includes encrypted network information, sending a message, to a network call controller, requesting establishment of said second call, where said message includes said encrypted network information.
In a connection-oriented network including a plurality of interconnected call controllers, a client call controller comprising:
In a connection-oriented network including a plurality of interconnected call controllers, a client call controller comprising:
At a source client call controller connected to a connection-oriented network including a plurality of interconnected network call controllers, a method of requesting the establishment of a given call to a destination client call controller, said method comprising:
A client call controller connected to a connection-oriented network including a plurality of interconnected network call controllers, said client call controller comprising:
At a network call controller in a connection-oriented network including a plurality of interconnected network call controllers, a method of call processing comprising:
In a connection-oriented network including a plurality of interconnected network call controllers, a network call controller comprising:
In a connection-oriented network including a plurality of interconnected network call controllers, a method of call processing at a network call controller comprising:
In a connection-oriented network including a plurality of interconnected network call controllers, a network call controller comprising:
At a network call controller in a connection-oriented network including a plurality of interconnected network call controllers, a method of call processing comprising:
In a connection-oriented network including a plurality of interconnected network call controllers, a network call controller comprising:
At a client call controller connected to a connection-oriented network including a plurality of interconnected network call controllers, a method of using information about a first call when requesting a second call, said method comprising:
A client call controller connected to a connection-oriented network including a plurality of interconnected network call controllers, said client call controller comprising:
At a network call controller in a connection-oriented network including a plurality of interconnected network call controllers, a method of message processing comprising:
In a connection-oriented network including a plurality of interconnected network call controllers, a network call controller comprising:
At a client call controller connected to a connection-oriented network including a plurality of interconnected network call controllers, a method of requesting a call comprising:
