Abstract
Abstract A method of operating a switched communications network redirects certain types of messages away from the switch to free up switch resources for other messages, thereby decreasing the size of switch needed or delaying necessary switch size upgrading. Messages are redirected by intelligent concentrators that can connect certain types of messages to their destinations without routing them through the switch. For example, messages between an origination and a destination connected to the same concentrator need not be sent through the switch. Similarly, messages between originations and certain high-volume, long-duration destinations such as data service gateways can be connected directly without passing through the switch. The intelligent concentrators communicate with the switch on a control channel so that the switch remains aware of the status of each origination or destination (e.g., so that it knows not to attempt to route messages to an origination or destination that is in use).
