Publication number: 20150304452Abstract: A method is provided for maintaining session state in a Secure User Plane Location (SUPL) enabled system during a triggered session. The method includes modifying at least one parameter of a session message to include state data indicating the session state, and transmitting a request to a SUPL Enabled Terminal (SET) to initiate the triggered session, the request comprising the session message having the at least one modified parameter to be stored at the SET. The method further includes receiving a triggered message from the SET in response to occurrence of a trigger event detected by the SET, the triggered message comprising the stored state data. The triggered session is identified using the state data received in the triggered message.Type: ApplicationFiled: June 30, 2015Publication date: October 22, 2015Applicant: TELECOMMUNICATION SYSTEMS, INC.Inventors: NGUYEN KHIEM TRAN, MARTIN WYVILLE THOMSON, DARREN PAWSON

Patent number: 8380223Abstract: An apparatus and method are provided for processing requests by a stand-alone serving mobile location center (SAS), shared by multiple radio access networks in a wireless network, for determining locations of mobile devices within the wireless network. A positioning request message for a mobile device is received from a radio network controller (RNC) in a radio access network (RAN) of the multiple radio access networks. An originating point code (OPC) and a cell identifier are retrieved from the positioning request message. A mobile country code (MCC) and a mobile network code (MNC) corresponding to the RAN are determined based on the retrieved OPC. A serving network node communicating with the mobile device is identified using the cell identifier and the determined MCC and MNC.Type: GrantFiled: September 16, 2009Date of Patent: February 19, 2013Assignee: Andrew LLCInventors: Darren Pawson, Nguyen Khiem Tran

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: 8217832Abstract: A system and method for determining a location of a wireless device in a communications network. A request for satellite assistance data may be received from a requesting entity, and a reference location determined as a function of the request. One or more characterizing attributes may be identified as a function of the reference location, and a set of satellites determined as a function of the reference location. It may also be determined whether more than one set of signal measurements should be acquired from one or more satellites in the set of satellites as a function of the identified one or more characterizing attributes. The one or more sets of signal measurements may be acquired, and a location of the wireless device determined from the acquired measurements.Type: GrantFiled: September 23, 2009Date of Patent: July 10, 2012Assignee: Andrew, LLCInventors: Martin Wyville Thomson, Neil Lindsay Harper, Nguyen Khiem Tran
