Patent 7813491 was granted and assigned to AT&T Intellectual Property I on October, 2010 by the United States Patent and Trademark Office.
A method of AIN query redirection is performed by a first SCP in a telecommunication network. The first SCP receives a query from an originating SSP and determines that a second SCP should service the query. The query is then populated with information from the originating SSP as well as appropriate routing information to send the query to a second SCP where a response is generated by the second SCP. The query response is sent back from the second SCP to the originating SSP without passing through the first SCP.
