Abstract:
1. A method for routing calls in a distributed mobile switching center environment, the distributed mobile switching center including at least a plurality of Media Gateways and a Mobile Switching Center Server, the method comprising: receiving a call at a first node in a telecommunication network, wherein the first node includes a plurality of Media Gateways, the first node associated with a plurality of trunks; identifying an interconnection constraint comprising at least one of a preference and a restriction relating to selection of a circuit among a plurality of circuits associated with one of the plurality of trunks associated with the first node for routing the call; and routing the call to a trunk in accordance with the interconnection constraint, wherein the plurality of Media Gateways further comprises a cluster comprising a single switch that uses a single set of routing translations, wherein the first node comprises one of a plurality of IO nodes operable to handle bearer traffic, each of the plurality of IO nodes operating under control of a server implementing signaling traffic associated with the bearer traffic; wherein the constraint relates to one of a preference or a restriction against routing the call through an interconnection with another of the plurality of nodes; and wherein the preference comprises: selecting a circuit associated with the first node for routing the call if a circuit associated with the first node is available; and allowing use of a circuit associated with a particular other one of the plurality of nodes through an interconnection with the particular one of the plurality of nodes if a circuit associated with the first node is not available.
