Abstract: A GNSS enabled handset receives signals from different resources comprising GNSS satellites and/or from a wireless network. The GNSS enabled handset acquires location information comprising various positioning resource data comprising GPS data and/or WiFi data from the received signals. The GNSS enabled handset calculates a plurality of possible position fixes based on the acquired location information using various positioning approaches. A current position fix associated with the GNSS enabled handset is determined based on the plurality of calculated possible position fixes via running a location-based service (LBS) client on the GNSS enabled handset. The LBS client determines the plurality of possible position fixes using various positioning approaches in a particular or determined order. Confidence levels for each of the calculated plurality of possible positions are determined and used to refine the current position fix.

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 client device dynamically selects one of client based location computation and server based location computation, based on propagation environment around the client device, to determine its own location. The client device may switch between client based location computation and server based location computation based on the local propagation environment for a desired quality of location and low data load from a remote location server. The client device measures power of received radio transmissions from radio transmission sources such as WLAN access points and/or cellular base stations. For a client based location solution, the client device performs location computation utilizing the local power measurement and assistance data downloaded from the remote location server. For a server based location solution, the remote location server may perform location computation for the client device.

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 GNSS capable LBS client device sends a device RF environment report to a location server and subsequently receives a capture profile from the location server. A new RF environment report is generated according to the received capture profile. The device RF environment report comprises various encountered RF information, for example, state of radios, state of power and/or memory resource, and/or positioning variables.

Desired RF environment data are captured according to the received capture profile, and time and location stamped to generate the new device RF environment report, which is sent to the location server to update the reference database to enhance locating the GNSS capable LBS client device when need.

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.

Abstract: Aspects of a method and system for global position reference map (GPRM) for AGPS are provided. A GPS enabled device may transmit reference location data to a location server and responded with a global position reference map (GPRM) from the location server. The reference location data and/or the received GPRM may comprise reference positions, which may be any identifiable location information, for the GPS enabled device. The reference location data may be formatted via various location identifiers such as a RNC ID, MCC and/or a MNC indicating desired coverage areas for the received GPRM. The reference location data may be a portion of a reference position database inside the GPS enabled device. The reference position database may be updated via the received GPRM. A fast position fix for the GPS enabled device may be achieved by combining AGPS data or LTO AGPS data, and the reference position database.
