摘要： Methods and systems are employed by a wireless location system (WLS) for locating a wireless device operating in a geographic area served by a wireless communications system. An exemplary method includes monitoring a set of signaling links of the wireless communications system, and detecting at least one predefined signaling transaction occurring on at least one of the predefined signaling links. Then, in response to the detection of the at least one predefined network transaction, at least one predefined location service is triggered.

摘要： By combining imaging systems with wireless location functionality, a subject's videometric signature can be linked to a public identity, thus enabling continuous surveillance outside or between the coverage area of video surveillance networks. In addition to extending the surveillance coverage area, the combination of computerized video surveillance with wireless location determination may also allow for identification of mobile device users via the existing mobile equipment and user identifiers used in the wireless network.

摘要： A method for use in controlling a mobile device's access to one or more wireless communications networks (WCNs) with an overlaid wireless location system (WLS) includes monitoring a set of one or more predefined signaling links of at least one WCN, and detecting an event associated with the mobile device. Next, using a low-accuracy location function of the WLS, the system determines that the mobile device is within a defined area of interest and is potentially within a defined quiet zone. Next, using a high-accuracy location function of the WLS, the system determines a precise geographic location of the mobile device and based thereon confirms that the mobile device is within the quiet zone or at least within an area of ambiguity around the quiet zone. Finally, the mobile device's access to the wireless communications network is limited, e.g., according to a pre-defined rule established by the carrier. This approach allows finer definition of the fenced area while also minimizing the load on the high-accuracy location function. The proximity threshold is preferably based on the accuracy of the underlying location technology.

摘要： One illustrative embodiment takes the form of a system for locating wireless transmitters employing an Orthogonal Frequency Division Multiplexing (OFDM) digital modulation scheme. The OFDM scheme comprises transmitting signal components over narrowband frequency channels spanning a wideband channel. The system includes a first receiving system configured to receive a fraction of the signal components transmitted by a first wireless transmitter to be located in a fraction of the narrowband frequency channels, and to process the fraction of the signal components to derive location related measurements. The system further includes at least a second receiving system configured to receive the fraction of the signal components transmitted by the first wireless transmitter, and to process this fraction of the signal components to derive location related measurements. The system also includes a processing system configured to use location related measurements from the first and second receiving systems to compute the location of the wireless transmitter.

摘要： A method for improving the results of radio location systems that incorporate weighted least squares optimization generalizes the weighted least squares method by using maximum a posteriori (MAP) probability metrics to incorporate characteristics of the specific positioning problem (e.g., UTDOA). Weighted least squares methods are typically used by TDOA and related location systems including TDOA/AOA and TDOA/GPS hybrid systems. The incorporated characteristics include empirical information about TDOA errors and the probability distribution of the mobile position relative to other network elements. A technique is provided for modeling the TDOA error distribution and the a priori mobile position. A method for computing a MAP decision metric is provided using the new probability distribution models. Testing with field data shows that this method yields significant improvement over existing weighted least squares methods.

摘要： Several techniques for locating wireless devices involve the Mobile Stations (MS) making measurements of the signals transmitted by geographically distributed base stations within a wireless network. If some key site information is known about these transmitters, such as the transmitter location, transmit signal power, signal propagation, and transmit signal timing, measurements of these transmit signals by a MS can be used to determine the position of the MS. An automatic method to detect transmitters, identify key transmitter information, and utilize the base station transmit signals to perform location is presented. In addition, this method facilitates the use of cell site transmit signals that are part of multiple wireless networks.
