Abstract
A system and method are described for providing and using an inter-working location gateway (IWLG) that allows a trusted/non-trusted user plane mobile node to successfully utilize user location services while data roaming. In an embodiment, once the mobile node establishes a data connection while roaming, the mobile node uses IP connectivity to exchange messages, e.g., IS-801 messages, with an IWLG located in the home network. Via the messaging, the mobile node provides certain parameters which the IWLG uses to determine which network the mobile node is roaming. The IWLG interfaces with the appropriate network elements in the visited network to determine the location of the mobile node.
