Abstract:
In a wireless communications system comprising first and second interconnected mobile switching centers, an internet protocol network, a first media gateway and a second media gateway, the first and second mobile switching centers coupled to the first and second media gateways, respectively, and wherein the first and second mobile switching centers are further coupled to the internet protocol network, a method of reducing the use of circuit connections between the mobile switching centers comprising the steps of:a) the first mobile switching center transmitting a transaction identifier to both the first media gateway and second mobile switching center; b) the second mobile switching center transmitting a control message to the second media gateway requesting a redirection of speech packets over the internet protocol network; c) the second media gateway transmitting the control message to the first media gateway requesting a redirection of speech packets having a predetermined address to said internet protocol network; and d) transmitting said speech packets over said internet protocol network using said transaction identifier thereby reducing the use of circuit connections between said first and second interconnected mobile switching centers.
