System and method for executing signalling cut-through
First Claim
1. A method for eliminating signalling connections in a network, comprising the steps of:
- a) establishing a first local connection, a second local connection and a transit connection;
b) selecting a gateway to handle signalling resources;
c) establishing a third local connection with the selected gateway; and
d) eliminating the transit connection and one of the first and second local connections.

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.

11. A method for eliminating signalling connections in a network, comprising the steps of:
-
a) establishing a first local connection between a first gateway and a first subscriber unit; b) establishing a transit connection between the first gateway and a second gateway; c) establishing a second local connection between the second gateway and a second subscriber unit; d) selecting a selected gateway from the first gateway or the second gateway based on which of the first gateway or the second gateway is first to perform a voice cut-through; and e) executing a signalling cut-through so that only the selected gateway services the network for a call between the first subscriber unit and the second subscriber unit. - View Dependent Claims (12, 13)

14. A system comprising:
-
a first subscriber unit; a second subscriber unit; a first gateway capable of establishing a first local connection to the first subscriber unit; and a second gateway capable of establishing a transit connection to the first gateway and a second local connection to the second subscriber unit, wherein the first gateway is capable of establishing a third local connection to the second subscriber unit and eliminating the transit connection and the second local connection.
