Patent number: 9736627Abstract: As part of a localized positioning solution, a mobile device may transmit a request message to a server to obtain information about location contexts near the mobile device. In response, the server may, in some implementations, transmit a response message back to the mobile device that identifies a list of nearby LCIs and an area that encompasses these LCIs. The mobile device may store the returned LCI information and the returned area information in corresponding databases for later use. In some implementations, time limits may be placed on the returned area information after which the information is deemed stale.Type: GrantFiled: September 8, 2014Date of Patent: August 15, 2017Assignee: QUALCOMM IncorporatedInventors: Eric K. Holm, Arie Rahmat, Rajarshi Gupta

Publication number: 20170074972Abstract: Disclosed are methods, systems and devices for providing location based services in a venue. To estimate its location, in a particular implementation, a mobile device may obtain a measurement of a range to a transponder device positioned at a known location based on measurements of a signal round-trip time (RTT) in a message exchange with the transponder device. Positioning assistance data from a server may enable the mobile device to measure a delay at the transponder device in providing a response to a probe message to thereby more accurately measure the signal RTT.Type: ApplicationFiled: November 28, 2016Publication date: March 16, 2017Inventors: Ju-Yong Do, Gengsheng Zhang, Sundar Raman, Chandrakant Mehta, Arie Rahmat, Lionel Jacques Garin

Patent number: 9357473Abstract: Disclosed are a system, apparatus, and method for adaptive discovery and scanning of wireless access points. In one embodiment, a set of channels can be scanned in a first iteration to discover wireless access points. In one embodiment, a discovery profile based on the discovered wireless access points can be determined and in a second iteration, a subset of the set of channels can be scanned. In one embodiment, the subset consists of non-overlapping channels selected according to the discovery profile.Type: GrantFiled: March 12, 2013Date of Patent: May 31, 2016Assignee: QUALCOMM INCORPORATEDInventors: Jeemil N. Shah, Ashok Bhatia, Yuhua Hu, Gengsheng Zhang, Arie Rahmat

Publication number: 20150212191Abstract: Method, device, computer program product, and apparatus for performing and processing mobile device positioning are described. A mobile device can request vertical positioning assistance. The mobile device can receive vertical positioning assistance from a transmitter classified for vertical positioning assistance. The mobile device can receive optimized assistance data created in response to a particular positioning request. The optimized assistance data may be optimized for vertical position, horizontal positioning, or both usage types. The mobile device can receive usage type classifications directly from a transmitter. A server can receive and determine a request is a vertical positioning request. Vertical positioning can include determining one or more of: an altitude, floor, level, or any combination thereof, within the environment.Type: ApplicationFiled: September 23, 2014Publication date: July 30, 2015Inventors: Gengsheng Zhang, Ju-Yong Do, Sundar Raman, Chandrakant Mehta, Arie Rahmat, Sunil Patel

Patent number: 8634785Abstract: In a radio frequency (RF) receiver, a receiver RF chain is tuned to a first (e.g., global positioning system (GPS)) channel to permit receipt of a first (e.g., GPS) signal over the first (e.g., GPS) channel on the receiver RF chain during a first time duration. The receiver RF chain is tuned to a second (e.g., cellular page) channel to permit receipt of a second (e.g., cellular page) signal over the second (e.g., cellular page) channel on the receiver RF chain during a second time duration, following the first time duration. The first (e.g., GPS) signal is processed during the first time duration and the second time duration, without any apparent interruption of the first (e.g., GPS) signal during the second time duration. The processing, for example, provides a bridge signal (e.g., an estimated GPS signal on the receiver RF chain) during the second time duration.Type: GrantFiled: April 28, 2009Date of Patent: January 21, 2014Assignee: QUALCOMM IncorporatedInventors: Ashok Bhatia, Dominic Gerard Farmer, Douglas Neal Rowitch, Douglas Grover, Arie Rahmat, Chang Shik Row

The processing, for example, treats the actual interruption as a temporary, short term fade of the first (e.g., GPS) signal during the second time duration, or provides a bridge signal (e.g.Type: ApplicationFiled: April 28, 2009Publication date: November 5, 2009Applicant: QUALCOMM IncorporatedInventors: Ashok Bhatia, Dominic Gerard Farmer, Douglas Neal Rowitch, Doulgas Grover, Arie Rahmat, Chang Shik Row
