Abstract
A servicing communication device may receive a subset of a location reference database that is maintained by a plurality of location servers, and may provide location related data to a mobile device that is communicatively coupled to the servicing communication device based on the received subset. The servicing communication device may determine capabilities and/or requirements of the mobile device, and may generate the location related data based on that determination. The servicing communication device may determine attributes and/or parameters that may affect determination of the subset of the location reference database. The subset of location reference database may be requested based on the determined attributes and/or parameters. The attributes and/or parameters may comprise a location of the servicing communication device. The servicing communication device may determine its location, directly based on GNSS transmissions and/or indirectly based on assisted GNSS (A-GNSS) data received from the plurality of location servers.
