Abstract
The invention relates to a data communications network and a method of operation thereof. A data communications network (14) is described which includes a call server (58, 60, 62, 64) for the purpose of signalling, and a routing server (66, 68) for the purpose of routing to permit communication between users of the network. The call server (58, 60, 62, 64) is operable to send a request to the routing server (66, 68) for the purpose of obtaining the identity of another call server (58, 60, 62, 64) to which it is required to communicate. The request is provided with a parameter which relates to the origin of the communication within the data network (14) to enable a desired routing of the communication through the network.
Claims23
A data communications network comprising:
- a routing server configured to route communications between users of the network;
- and
- a first call server configured to send a request to the routing server to obtain an identity of a second call server with which the first call server is required to communicate, the request including a parameter that identifies an origin of a communication within the data network, and that is used to route the communication through the data network.
A method of operating a data communications network having a first call server and a routing server, the method comprising:
- sending a request from the first call server to the routing server to obtain an identity of a second call server that is required to communicate with the first call server, the request including a parameter that identifies an origin of a communication within the data communications network;
- and
- routing, by the routing server, the communication through the data communications network from the first to the second call server based on the parameter that identifies the origin of the communication within the data communications network.
