摘要
A method of enabling a home network to identify a location of its subscriber roaming within a visited network. An Intelligent Data Routing (IDR) application functions as a proxy between a Serving GPRS Support Node (SGSN) of the visited network and a Gateway GPRS Support Node (GGSN) of the home network. The IDR receives a Create PDP Context Request message or an Update PDP Context Request message that is sent from the SGSN to GGSN. The IDR determines whether the Routing Area Identity (RAI) and User Location Information (ULI) Information Elements (IEs) of the Request message have been populated by the SGSN. If the IDR application determines that at least one of these IEs is absent, the IDR application populates them with appropriate values obtained from the SGSN. The routing application sends the modified Request message having the populated RAI and ULI IEs to the GGSN.
