System and method for having a single gateway set-up and maintain local signalling connections

摘要

A system (10) and method (100) selects one of the gateways (40, 41) to set-up and maintain signalling resources associated with a call. Instead of having two gateways (40, 41) handle signalling resources, a single gateway (40) becomes the serving gateway for one or both of the subscriber units' call segment. The system and method do not establish a transit connection between gateways (40, 41).
