Abstract: A Femtocell measures power from a serving and/or neighboring base stations in a radio access network specified in, for example, 3GPP, 3GPP2 and/or WiMAX. The power measurements are transmitted over a broadband IP network to a location server coupled to an associated mobile core network. Related location information comprising reference positions and/or actual location of the Femtocell are received from the location server over the broadband IP network. The Femtocell generates measurement reports of a serving and/or neighboring base stations in the radio access network. The generated measurement reports are transmitted to the location server over the broadband IP network. The location server identifies the reference positions of the Femtocell from a reference database based on the received measurement reports for calculating the location of the Femtocell by the location server and/or by the Femtocell itself. The calculated location of the Femtocell is used to update the reference database.

Abstract: Aspects of a method and system for customized full ephemeris compatible with standard AGPS network devices allows a GPS enabled handset to receive real-time full ephemeris from an AGPS server for calculating a position fix. The real-time full ephemeris may be generated at the AGPS server in response to one or more request for real-time full ephemeris from the GPS enabled handset. The AGPS server may be configured to provide fresh full ephemeris generated at smaller intervals such as every 10-15 minutes as approximated real-time full ephemeris. The generated real-time full ephemeris or fresh full ephemeris may be communicated to the GPS enabled handset periodically or aperiodically. Various predicted real-time full ephemeris or predicted fresh full ephemeris compatible with various standards may be generated via Short Term Orbits (STO) technology.

Abstract: A multi-magnetometer device comprises at least two z-axis aligned and physically rotated magnetometer triads utilized for measuring corresponding earth's magnetic field. The magnetic field measurements are utilized to measure rotation measurements of a single orthogonal axis along the 360 degrees of the complete circle without user's assistance and/or magnetometer movement for magnetometer calibration. The multi-magnetometer device may compute its magnetic heading utilizing the magnetic field measurements if no magnetic perturbations are detected. When magnetic perturbations are detected, a perturbation mitigation process may be performed. The rotation measurements may be generated by selectively combining the magnetic field measurements. Hard-iron components are determined utilizing the rotation measurements, and are removed from the magnetic field measurements.

Abstract: Embodiments enable higher accuracy GNSS performance by generating local/regional ionosphere models tailored to specific local/regional areas of interest and by using location-based delivery of the local/regional ionosphere models to mobile GPS receivers. Different types and levels of reference locations (e.g., Cell ID (CID), Location Area Code (LAC), Radio Network Controller ID (RNC-ID), Mobile Country Code (MCC)) can be used to estimate the location of mobile GPS receivers and to deliver the appropriate local/regional ionosphere models to the mobile GPS receivers. According to embodiments, the local/regional ionosphere models are fit into the same 8-parameter set as the broadcast global ionosphere model, therefore being compatible with existing GPS receivers that accept the broadcast global ionosphere model.

Abstract: A mobile device in a cellular communication network collects round-trip time (RTT) measurements for a single active cell. The collected RTT measurements are transmitted to a location server. The location server uses the transmitted RTT measurements to calculate a GNSS position of the single active cell. One or more of the transmitted RTT measurements are taken by the mobile device, and/or are collected from other mobile devices in the single active cell. The transmitted RTT measurements are collected at different GNSS fixes in the same single active cell. The mobile device location stamps the collected RTT measurements using corresponding GNSS fixes, and transmits to the location server using a NML. The location server calculates the GNSS position of the single active cell using location stamped RTT measurements in the received NMLR to refine an associated reference database periodically or aperiodically.

Abstract: A mobile device learns cell information for a serving cell and for neighbor cells. The learned cell information is communicated to a remote location server for locating base stations within the serving and/or neighbor cells. The learned cell information comprises cell signal strength information and/or other cell information such as cell identifiers (Cell-IDs) and Country Code (MCC). Received signal strength (RSS) on the serving cell and the neighbor cells are measured. Locations pertaining to the RSS measurements are determined. The mobile device location stamps the RSS measurements utilizing the determined locations to generate a neighbor cell report, which is utilized by a cellular communication network to prepare a handover operation whenever needed, and/or to build a local cell-learning database. A portion of the local cell-learning database is transmitted as cell data to the remote location server that collects cell data from a plurality of mobile devices.

Abstract: A method and system is presented for a global navigation satellite system (GNSS) enabled WCDMA handset to receive reference locations from a network location server based on RNC geographic service areas. The GNSS enabled WCDMA handset may generate a location request comprising an RNC ID and may determine its location based on the received reference location and/or received GNSS assistance data. The RNC geographic service area and/or an area of uncertainty may comprise one or more of a latitude, a longitude and uncertainty value. Accuracy of the RNC geographic service area and/or the area of uncertainty may be increased over time. The RNC service area may be determined by the network location server based on an average of a plurality of handset locations that are reported by handsets that are served by the RNC. Handset location reports may comprise the RNC ID.

A response from the mobile terminal may comprise its location. A navigation satellite system receiver such as GPS and/or GLONASS and/or an assisted navigation satellite system receiver may be utilized to determine the mobile terminal location. In addition, cell ID, location ID and/or network mobile report (NMR) information may be utilized to determine the mobile terminal location.
