Abstract:
1. A method for routing a signaling message in a telecommunication network, wherein the telecommunication network includes a first licensed operator network and second licensed operator network, the first licensed operator network including a first Border Node adjacent to a second Border Node of the second licensed operator network, the method comprising: providing a first numbering plan for use by the first licensed operator network, wherein the first numbering plan specifies the Point Codes used in the first licensed operator network; providing a second numbering plan for use by the second licensed operator network wherein the second numbering plan specifies the Point Codes used in the second licensed operator network and wherein the first and second numbering plans use a same Point Code configuration numbering plan; receiving at the first Border Node the signaling message comprising an Originating Point Code (CRC) and a Destination Point Code (DPC) in accordance with the first numbering plan; mapping the OPC and the DPC of the signaling message from the first to the second numbering plan; and delivering the signaling message from the first Border Node to a destination node of the telecommunication network according to the mapped OPC and DPC, wherein the destination node is in the second licensed operator network, the step of mapping the OPC and the DPC of the signaling message further including: checking in the MTP of the Border Node if the Link Set associated toward the destination node supports MTP Point Code Mapping, if so
