ABSTRACT:
Incoming calls or messages for a mobile station that has been ported from a first HLR to a second HLR are first received by a gateway node. The gateway node, in turn, transmits a signal requesting routing instruction to a centralized database connected to a gateway node. Utilizing the received Mobile Station Integrated Services Digital Network (MSISDN) number, the centralized database determines the network address of the new HLR currently serving the ported mobile station. The received signal requesting routing information is then routed to the new HLR. The new HLR retrieves the requested information and transmits it back to the gateway node. The gateway node, utilizing the received routing information received from the new HLR, accordingly routes the incoming calls or messages to the ported mobile station.
