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.

System and method for concurrently determining locations of mobile device in wireless communication network

A method is provided for processing emergency service calls from a user device to a PSAP, the user device having an associated line number and being configured to originate calls from fixed and mobile access networks. The method includes determining whether a call from the user device originates from a home location in a fixed access network. When the call is determined to have originated from the home location in the fixed access network, the call is routed to the PSAP, where a location of the user device is determined based on the Automatic Number Identification (ANI) included in signaling associated with the call. When the call is determined not to have originated from the home location in the fixed access network, adding pseudo-ANI to signaling associated with the call and routing the call to the PSAP, where the location of the user device is determined based on the pANI.

Enabling location determination of user device originating emergency service call

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.

Method and system for providing assistance data for A-GPS location of handsets in wireless networks

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.

System and method for determining the location of a mobile device

A system and method for determining an approximate location of a mobile device. The occurrence of a predetermined event may be determined at a first node of a network. Measurement data associated with the mobile device may be stored at a second node of the network. An attempt may be made to determine a location of the mobile device using a first location methodology. Upon failure of the location attempt, the mobile device data may be received at a third node of the network from the second node. At the third node an approximate location of the mobile device may be determined using the mobile device data.

Network measurement report caching for location of mobile devices

A system and method to arbitrate between SUP and CoPL LCS technology in a mized access network environment. The method includes signaling the serving network to obtain information prior to selecting a location determination session. The information is then indexed to a database to determine the location determination session desired.

Using serving area identification in a mixed access network environment

A system and method is disclosed that correlates the MSISDN of a target mobile by performing an out of band request using a IMSI. The correlation between the MSISDN and the IMSI of IMEI is cashed at a database for retrieval. The correlation of the MSISDN allows the position of a mobile device to be determined using a CoPL and/or SUPL location determination sessions.

Correlation mechanism to communicate in a dual-plane architecture

A system and method is disclosed that determines the position of a mobile device using information obtained by employing a first location determination protocol (or modality) to control the efficient or advantageous invocation of a second location determination protocol (or modality). The system utilizes information readily available from the Control plane along with request parameters and device capabilities to determine whether to invoke a CoPL or SUPL session.
