Patent ID: 7542559

Claim:
A method for alleviating the signaling system number network comprising: originating a message for a remote receiver from an originator subscriber; sending the message to an originator subscriber's home short messaging service center (SMSC): and routing the message to an intelligent routing server, wherein the intelligent routing server: validates against a carrier's own subscriber database to determine if the originator subscriber is a valid user of a particular service; and determines whether the remote receiver is one of its own carrier subscribers, wherein: if the intelligent routing server determines that the remote receiver is one of the carriers own subscriber's service provider, then the intelligent routing server routes the SMS to the appropriate SMSC; and if the intelligent routing server determines that the remote receiver is not one of its own subscriber's service provider, then the intelligent routing server performs a query to a Wireless Number Portability (WNP) database to determine a four digit service provider ID (SPID) for the destination remote receiver from the WNP database for the remote receiver, and uses the WNP data information to route the message over the intelligent routing server to the remote receiver.
