Abstract
A system (10) and method (100) reduce an amount of signalling resources used for calls involving more than one gateway (40, 41). Instead of having two gateways (40, 41) handle signalling resources, one gateway (40) becomes the serving gateway for a subscriber unit call segment. For signalling cut-through, a call is set-up in the usual way with a transit connection established between gateways (40, 41). After normal call set-up completed, including voice cut-through, signalling cut through is invoked to remove the need to maintain the transit connection and one local connection for the duration of the call. The old local connection is replaced with a new local connection to the serving gateway.
