System and method for a local number portability cache

摘要

A system and method for intelligently caching Local Number Portability queries from a Public Switched Telephone Network (PSTN). The apparatus may include: an intelligent communications platform connected between a switch and a Signaling System 7 (SS7) network to intercept Transactions Capabilities Applications Part (TCAP) messages between the switch and the SS7 network; and a communications control module connected to the intelligent communications platform via a Transmission Control Protocol/Internet Protocol (TCP/IP) link, the communications control module for providing management and communications to the ICP and providing access to the management and communication for a plurality of subscribers. The apparatus can also include: an SS7 I/O card for processing SS7 messages; and a CPU card for processing Integrated Services Digital Network User Part (ISUP) and TCAP messages. The communications control module can include instructions for receiving messages from other ICPs for updated information on LNP queries. The communications control module can also include instructions for the plurality of subscribers to view results of LNP queries.
