Patent number: 8325087Abstract: A system and method for determining whether a wireless device has transmitted one or more forged satellite measurements. An estimated location of the wireless device may be determined as a function of information from a cellular network. Acquisition assistance data may be determined for a first set of satellites as a function of the estimated location, the assistance data including an uncertainty window. If measured code phase information in the satellite measurements substantially correlates to the uncertainty window, then the wireless device may be transmitting forged satellite measurements.Type: GrantFiled: October 10, 2011Date of Patent: December 4, 2012Assignee: Andrew LLCInventors: Martin Thomson, Neil Harper

Patent number: 8301160Abstract: A system and method for assisting the H-SLP is selecting a V-SLP using the HELD client of a SET. The SET receives identity information from an access network regarding associated LIS. The SET relays this information as well as measurements taken of the wireless network to the H-SLP. If the H-SLP does not contain enough information to determine a location estimate, the H-SLP uses the identity information from the access network to find an associated SLP that may serve as a V-SLP. A request using roaming location protocol may then be transmitted from the H-SLP to the V-SLP for location assistance.Type: GrantFiled: June 10, 2010Date of Patent: October 30, 2012Assignee: Andrew LLCInventors: Martin Thomson, Anthony James Winterbottom, Nguyen Khiem Tran

Patent number: 8290510Abstract: A system and method for enhancing a SUPL session where a SET with a HELD client discovers an LIS of an access network and provides information received from the LIS or plurality of LISs to the SLP. The SLP determines the trustworthiness of the location information and estimates a location. The degree to which the SLP uses the location information is a function of the trustworthiness of the LIS and restraints on the location request. The location information may include a URI or domain name or other indication of location.Type: GrantFiled: May 19, 2010Date of Patent: October 16, 2012Assignee: Andrew LLCInventors: Martin Thomson, Anthony James Winterbottom, Nguyen Khiem Tran

Patent number: 8289210Abstract: A disclosed method uses the results of location queries to tune the value of measurements of a property to obtain a statistically representative measurement for geo location. As location requests arrive, a current measurement value associated with the serving area or location is used to determine the number of measurements to obtained; the resulting uncertainty is mapped against the number of measurements required to determine that value. If additional measurements are required to achieve the target uncertainty in the result, this is recorded. The process relies on empirical observations and has the additional advantage of being blind to the actual network topology. This approach by its own nature automatically takes into account network changes whether known or unknown.Type: GrantFiled: October 15, 2009Date of Patent: October 16, 2012Assignee: Andrew LLCInventors: Martin Thomson, James Winterbottom

Patent number: 8188920Abstract: The present subject matter discloses a method for estimating dilution of precision (DOP) across a service area. A Monte Carlo simulation is used to determine the DOP across a service area. Random points are selected across a service area and as well as the radio transmitters who signals are capable of being received at the random points are determined. Using the network topology of radio transmitters, a DOP is calculated for each of the random points. DOP is modeled for the service area as a function of the calculated DOP for each of the random points. The modeled DOP is used to determined the measurement accuracy required for subsequent location requests.Type: GrantFiled: October 15, 2009Date of Patent: May 29, 2012Assignee: Andrew, LLCInventors: Martin Thomson, James Winterbottom
