Patent number: 9648460Abstract: A method for forging location measurements at a wireless device can include determining, at the wireless device, a Cell-ID for a cell in a vicinity of a false location. The method can also include receiving, at the wireless device, an identification of a set of satellites that are within view from the false location. The method can further include generating, at the wireless device, forged location measurements that characterize satellite signals from a subset of the set of satellites that would be received at the false location. The method can still further include providing, from the wireless device, the forged location measurements.Type: GrantFiled: January 30, 2014Date of Patent: May 9, 2017Assignee: Telecommunication Systems, Inc.Inventor: Neil Harper

Publication number: 20160282475Abstract: A method for a mobile location center (MLC) to determine a location of a mobile device in a wireless communication network includes receiving a request to determine the location of the mobile device; concurrently requesting global navigation satellite system (GNSS) measurements from the mobile device and terrestrial measurements from transceivers in the wireless communication network, and receiving the GNSS measurements and at least one of the terrestrial measurements. A GNSS location of the mobile device is calculated as a function of the GNSS measurements, and the calculated GNSS location is determined to be the location of the mobile device when the calculated GNSS location meets a predetermined accuracy threshold. A terrestrial location of the mobile device is calculated as a function of the terrestrial measurements, and the calculated terrestrial location is determined to be the location of the mobile device when the calculated terrestrial location meets the predetermined accuracy threshold.Type: ApplicationFiled: June 8, 2016Publication date: September 29, 2016Inventors: Neil HARPER, Martin DAWSON

Patent number: 8718673Abstract: A system and method for determining whether an estimated location of a wireless device includes one or more forged location measurements. A first estimated location of the wireless device using a first set of location measurements is determined, and a second estimated location of the wireless device using a second set of location measurements is determined. The first estimated location may be compared to the second estimated location. One of the determined locations may then be identified as having one or more forged location measurements if the comparison between the first estimated location and second estimated location is greater than a predetermined threshold. The second set of location measurements may be produced using a location technology different than the location technology used to produce the first set of location measurements.Type: GrantFiled: May 20, 2011Date of Patent: May 6, 2014Assignee: Maple Acquisition LLCInventor: Neil Harper

Patent number: 8638259Abstract: A system and method for determining the location of a wireless device. A boundary for an approximate area in which the wireless device is located is determined and a plurality of satellites may be determined as a function of the boundary. Assistance data is transmitted to the device which includes information from the plurality of satellites, and the location of the wireless device may be determined from the information. In one embodiment, if the number of the plurality of satellites is greater than a predetermined threshold then the number of satellites may be reduced as a function of one or more of the elevation of each satellite above the horizon, a distance between each satellite to one or more other satellites, and an altitude of each satellite.Type: GrantFiled: September 1, 2010Date of Patent: January 28, 2014Assignee: Maple Acquisition LLCInventors: Neil Harper, Martin Dawson, Martin Thomson

Patent number: 8467805Abstract: A system and method for providing assistance data to a wireless device. A location request may be received for the wireless device, the location request identifying location information for the wireless device. A reference location for the wireless device may then be determined as a function of a comparison of the location information and a region determined as a function of at least one of a mobile country code (“MCC”), mobile network code (“MNC”), and an Area-Identification (“Area-ID”), such as a location area code (“LAC”) or a Radio Network Controller-Identification (“RNC-ID”). Assistance data may be provided to the wireless device as a function of the determined reference location.Type: GrantFiled: May 8, 2009Date of Patent: June 18, 2013Assignee: Andrew LLCInventor: Neil Harper

Patent number: 8378888Abstract: A system and method for determining the location of a mobile device. A first set of signals from a plurality of radio frequency (“RF”) sources may be received at a mobile device and then downconverted into a second set of signals. The mobile device may then time stamp the second set of signals and transmit the time stamped signals to a location determining system. The location of the mobile device may be determined at the location determining system as a function of the time stamped signals.Type: GrantFiled: February 28, 2012Date of Patent: February 19, 2013Assignee: Andrew LLCInventors: Neil Harper, Martin Dawson

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: 8299961Abstract: A system and method for determining one or more satellites in view of a wireless device. A request for satellite assistance data may be received from a requesting entity and a reference location determined as a function of the request. A set of satellites may be determined as a function of the reference location. Subsequent cached information may be determined for each satellite in the set of satellites if cached information already existing for each satellite in the set of satellites has been cached for greater than a predetermined time period. This subsequent cached information may then replace the previously existing cached information for the reference location. One or more satellites in view of the wireless device may then be determined as a function of either the subsequent cached information or previously existing cached information, and assistance data may be provided to the requesting entity to determine an estimated location of the wireless device.Type: GrantFiled: July 25, 2011Date of Patent: October 30, 2012Assignee: Andrew LLCInventor: Neil Harper
