PROVIDING GNSS ASSISTANCE DATA VIA A WIRELESS LAN ACCESS POINT
First Claim
1. A method for communication, the method comprising:
- performing by one or more processors and/or circuits in a wireless mobile device, wherein whenever said wireless mobile device is within range of a wireless local area network (WLAN) access point;
receiving Global Navigation Satellite Systems (GNSS) assistance data broadcasted from said WLAN access point, wherein said GNSS assistance data are acquired by said WLAN access point from an associate network and/or a reference database that is communicatively coupled to a location server.

Abstract
A wireless mobile device, either a WLAN enabled mobile device or a Bluetooth enable device, which is within range of a WLAN access point, is operable to receive GNSS assistance data broadcasted from the WLAN access point. The GNSS assistance data are acquired by the WLAN access point from a reference database coupled to a location server. The broadcast GNSS assistance data comprise ephemeris data, LTO data, location information related to the WLAN access point and/or time information. The WLAN access point receives the acquired GNSS assistance data from the location server over a broadband IP network. The WLAN access point selects available resources for broadcasting the received GNSS assistance data to wireless mobile devices in range. The wireless mobile device receives the broadcast GNSS assistance data to calculate its own location. The calculated location of the wireless mobile device is used to update or refine the reference database.
