    • 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.
    • 服务通信设备可以接收由多个位置服务器维护的位置参考数据库的子集,并且可以基于所接收的子集向通信地耦合到服务通信设备的移动设备提供位置相关数据。 服务通信设备可以确定移动设备的能力和/或要求,并且可以基于该确定来生成位置相关数据。 服务通信设备可以确定可能影响位置参考数据库的子集的确定的属性和/或参数。 可以基于所确定的属性和/或参数来请求位置参考数据库的子集。 属性和/或参数可以包括服务通信设备的位置。 服务通信设备可以直接基于GNSS传输和/或间接地基于从多个位置服务器接收到的辅助GNSS(A-GNSS)数据来确定其位置。
