LBS support to CDMA mobiles while roaming on another network. IS-801 session data is routed by a routing gateway to a correct visited network PDE that contains correct BSA data, which is used to return assistance data to an interrogating mobile device. A standalone exemplary roaming LBS routing gateway (XRG) provides network connectivity between PDE equipment in multiple carrier networks. Conventional LBS roaming support is defined via the use of Mobile Position Centers (MPCs). The invention implements a roaming LBS gateway to enable roaming between CDMA carriers that are only using a PDE (Positioning Determining Entity) for this purpose, since a mobile position center (MPC) is typically an optional network node according to location based services (LBS) specifications.
1. A method of facilitating location based services (LBS) for a roaming mobile device, comprising: receiving IS-801 session data, at a physical LBS routing gateway, from a physical roaming mobile device in a visited carrier network;determining an address of a visited carrier network positioning enti
1. A method of facilitating location based services (LBS) for a roaming mobile device, comprising: receiving IS-801 session data, at a physical LBS routing gateway, from a physical roaming mobile device in a visited carrier network;determining an address of a visited carrier network positioning entity (PDE) containing position information associated with said physical roaming mobile device;routing said IS-801 session data to said visited carrier network PDE containing position information associated with said physical roaming mobile device; andtransmitting said position information to an interrogating device;wherein LBS roaming is facilitated between network carriers using said visited carrier network PDE that is distinct from an mobile positioning center (MPC) to provide said position information to said interrogating device; andwherein said physical LBS routing gateway is located outside of said visited carrier network and a home carrier network. 2. The method of facilitating location based services (LBS) for a roaming mobile device according to claim 1, wherein said received IS-801 session data determines: an identity of said visited carrier network; andan identity of a home network associated with said physical roaming mobile device. 3. The method of facilitating location based services (LBS) for a roaming mobile device according to claim 2, wherein: said identity of said visited carrier network includes a system ID (SID) and a network ID (NID). 4. The method of facilitating location based services (LBS) for a roaming mobile device according to claim 1, wherein: said mobile device is a CDMA device. 5. The method of facilitating location based services (LBS) for a roaming mobile device according to claim 1, wherein: said physical LBS routing gateway is located outside of said visited carrier network. 6. The method of facilitating location based services (LBS) for a roaming mobile device according to claim 1, wherein: said physical LBS routing gateway is located outside of a home carrier network. 7. A method of facilitating location based services (LBS) for a roaming mobile device, comprising: receiving IS-801 session data, at a physical LBS routing gateway, from a physical roaming mobile device in a visited carrier network;determining an address of a visited carrier network positioning entity (PDE) containing position information associated with said physical roaming mobile device;routing said IS-801 session data to said visited carrier network PDE containing position information associated with said physical roaming mobile device;transmitting said position information to an interrogating device;querying a PDE route table to determine an Internet protocol (IP) address and port number of said visited carrier network PDE; andestablishing a TCP/IP connection between said physical LBS routing gateway and said visited carrier network PDE;wherein LBS roaming is facilitated between network carriers using said visited carrier network PDE that is distinct from an mobile positioning center (MPC) to provide said position information to said interrogating device.
