Abstract:
1. A Signaling System No. 7 (SS7) node for sharing transaction capabilities application part (TCAP) traffic load from a SS7 subnet with one or more nodes in another SS7 subnet, comprising: a first interface for said SS7 subnet; a second interface for said another SS7 subnet; a processor in communication with said first and second interfaces and with one or more structured data storages, wherein said processor carries out a process of sharing said TCAP traffic load from said SS7 subnet with one or more nodes in said another SS7 subnet, said process comprising: receiving a TCAP message from said SS7 subnet through said first interface; extracting originating point code (OPC), destination point code (DPC) and transaction identifier (TID) of said TCAP message; looking up and retrieving, from said one or more structured database storages, a corresponding OPC, a corresponding DPC and a corresponding TID for one of said one or more nodes in said another SS7 subnet partially or combinedly based on said OPC, said DPC and said TID of said received TCAP message; and replacing said OPC, said DPC and said TID of said received TCAP message with said corresponding OPC, said corresponding DPC, and said corresponding TID; forwarding said TCAP message with said corresponding OPC, said corresponding DPC, and said corresponding TID to said another SS7 subnet; and prior to looking up and retrieving said corresponding OPC, said corresponding DPC and said corresponding TID, said processor further takes the steps of:
