Abstract
A method for routing bearer traffic (70′) between 3G networks (32, 42) and 2G networks (12, 22) and vice versa uses voice signaling gateways (VSGW)(14, 24, 34, 44). The method determines a VSGW nearest the calling party (11). The nearest VSGW directly routes (86) the bearer traffic through the inter-network (50) to the called party (31) and avoids the “tromboning” effect of always sending bearer traffic to the called party's home location.
Claims17
In a communication system a method for routing bearer traffic between a 3G network and a 2G network, the method for routing bearer traffic comprising the steps of:
- if a calling party is roaming into a first network, determining by the first network a local gateway of the first network and in proximity to a calling party;
- sending the bearer traffic by the first network to the local gateway;
- and
- directly routing the bearer traffic from the local gateway to a called party through a second network in proximity to the called party.
