摘要:
A novel system and method for a network overlay geolocation system operating in a host wireless communication system with repeaters is disclosed. Embodiments of the novel system and method enable wireless communication system to determine if signals being received by system receivers arrive directly from a target mobile appliance or if the signals are passing through a repeater. The system's determination may be based at least in part on the TA of the signal, the power of the received signal, the power of the transmitted signal, the hearabiltiy of the signal at system receivers, the hearabiltiy of system transmitters at the mobile and the known delays associated with the repeaters. Embodiments of the novel system and method provide a more accurate geolocation of mobiles served by repeater stations than capable in the prior art.

A novel system and method for tasking and reporting the geolocation of a mobile appliance for a wireless communications network overlay system is disclosed. Embodiments of the novel system and method allow for geolocating a mobile appliance regardless of the wireless air interface protocol standard utilized by the mobile appliance.
摘要:
A system and method for geolocating a mobile unit from a single base station is described. Communication signals and pilot signal information from a mobile unit are received at a base station with randomly-located antennas. Certain parameters of the signals are detected and a set of real-time, but ambiguous, location measurements is determined. The real-time measurements are compared to reference measurements previously stored in a database, indexed by range and bearing from the base station, to find the best match and thereby the geolocation of the mobile unit. A time history of the mobile unit's position is stored and compared with static information from maps and other geomorphological data to further refine the geolocation of the mobile unit.

A system for monitoring each channel of the communication link (307) for protocol messages and identifying a set of channels with valid protocol messages and, monitoring the set of channels to determine the transceivers (309) served by the set of channels and associating the transciver (309) with respective channels from the set of channels.
摘要:
A system and method supports multiple wireless carrier mobile station location requirements with a common network overlay location system. The common network overlay location system shares geolocation assets such as location measurement units (LMU), geo-location control system (GCS), and, optionally, mobile positioning centers (MPC). The shared location assets are configured to operate with each of the sharing carrier systems. The number of sharing carriers in the same market is not limited. LMUs are configurable and switchable to measure attributes of the transmitted signal from mobile stations belonging to any of the wireless carriers which are used by the common location system to estimate the location of the mobile station using time of arrival, time difference of arrival, angle of arrival, signal power, and combinations of the same. The location of the LMUs are configured to provide an acceptable level of accuracy while minimizing a function such as the need for additional LMUs and cost.

A system and method for a network analysis system operating in a wireless communication system with repeaters is disclosed. Embodiments of the system and method enable the network analysis system to determine if signals being received by the network receivers arrive directly from a target mobile appliance or if the signals are passing through a repeater. The repeaters through an augmentation measure attribute of a received signal to a network manager and based on these attributes it is determine whether the signal is served by a repeater or other network device.

摘要:
A system and method for determining the geolocation of autonomous mobile appliances using timing measurements from reference signals to determine position. The system and method allows the use of reference signals from disparate communication and navigation networks of which the mobile appliance may or may not be a network member. The system and method also maintains and dynamically updates its database of the location of reference signal transmitters and the reference signals emitted by the reference signal transmitters upon the detection of new reference signals or when the geolocation solution of a mobile appliance is over-determined.
