  • Patent number: 6130940
    Abstract: A "Local Number Portability (LNP) intelligent Signal Transfer Point (STP)" which can perform a Local Number Portability (LNP) query towards a Service Control Point (SCP) and modify the incoming Initial Address Message (IAM) with the Location Routing Number (LRN) and the Ported Dialed Number (PDN), and indicate, using the Forward Call Indicator (FCI) (M-bit), whether the number has been translated. This advantageously allows non-Advanced Intelligent Network capable Service Switching Points (SSPs) (but Integrated Services Digital Network User Part, or ISUP, capable SSPs) to support Local Number Portability (LNP) without having to upgrade the SSP's. In addition, the LNP intelligent STP system provides AIN-capable SSPs with an alternative means of LNP, which reduces both the internal switching processes and the cost for the LNP query transactions.
