  • Publication number: 20080096527
    Abstract: Techniques to support positioning of roaming mobile stations are described. A roaming mobile station communicates with a visited network and has a data connection to a home network. The mobile station sends a request for positioning assistance to a home position determining entity (H-PDE) in the home network. The H-PDE determines that base station almanac (BSA) data applicable for the mobile station is not locally available and sends a request for location information for the mobile station to a designated network entity. This entity may be a BSA server storing BSA data for different networks or a visited PDE (V-PDE) in the visited network. The H-PDE receives location information (e.g., BSA data, assistance data, and/or a position estimate for the mobile station) from the designated network entity and provides positioning assistance to the mobile station based on the received location information.

  • Publication number: 20060271517
    Abstract: A method, system, and computer-readable medium bearing instructions for calibrating a location system are described. The method includes receiving connection information regarding the connection of a device to a network and querying a user to provide input regarding the physical location of the device. User input is received regarding the physical location of the device connected to the network and the connection information and user input are stored.

  • Publication number: 20050037775
    Abstract: Methods and apparatuses for position determination and other operations. In one embodiment of the present invention, a mobile station uses wireless signals from a plurality of wireless networks (e.g., with different air interfaces and/or operated by different service providers) for position determination (e.g., for data communication, for obtaining time and/or frequency information, for range measurement, for sector or altitude estimation). In one embodiment of the present invention, mobile stations are used to harvest statistical data about wireless access points (e.g., the locations of mobile stations that have received signals from the wireless access points, such as from cellular base stations, wireless local area network access points, repeaters for positioning signals, or other wireless communication transmitters) and to derive location information (e.g., position and coverage area of the wireless access points) for the wireless networks from the collected statistical data.
