Abstract
A cellular wireless core network for establishing calls via dynamic virtual circuit connections includes a source call server exchanging messages with a destination call server in order to determine a destination media gateway. The destination media gateway determines a destination logical ATM component and its logical ATM component address. The destination media gateway returns the destination logical ATM component address to the destination call server, which, in turn, returns the destination logical ATM component address to the source call server. The source call server forwards the destination logical ATM component address to a source logical ATM component. The source logical ATM component sends an Establish Request (ERQ) message to the destination logical ATM component containing the destination logical ATM component address, the source logical ATM component address, and a virtual circuit connection identifier that uniquely defines the virtual connection through the ATM network.
