SYSTEM AND METHOD FOR PROVIDING LOCATION-BASED SERVICES (LBS) TO ROAMING SUBSCRIBERS IN A WIRELESS ACCESS NETWORK
Document Type and Number:
WIPO Patent Application WO/2010/025036
Kind Code:
A3
Abstract:
Embodiments of a wireless access network and method for providing a location based service (LBS) to a visiting mobile station are disclosed. In some embodiments, a location data request forwarded by a home location server (HLS) is received at a visited location server (VLS). A subscriber profile and security query is generated for forwarding from a visitor authentication server to a home authentication server. When the home authentication server authenticates the request, location information for the visiting mobile station is obtained and a location data response message that includes the location information from the VLS is sent to the HLS for forwarding to the location client for use by the location client in performing a requested LBS.
