摘要： A method and system for determining an approximate range from a location measurement unit to a mobile device. An uplink signal from the mobile device is received by the location measurement unit, and an uplink frame marker is determined from the uplink signal. A downlink signal is received at the location measurement unit from a base station serving the mobile device, and a downlink slot marker is determined from the downlink signal. A round trip propagation delay is determined based upon the uplink frame marker and the downlink slot marker, and an approximate range from the location measurement unit to the mobile device is determined as a function of the round trip propagation delay.

摘要： A system and method for estimating a location of an unknown Node B in a wireless communication system having a plurality of other nodes and a plurality of location measurement units. A first value may be determined based on a network timing characteristic for one of the nodes, and a second value may be determined based on a network measurement report characteristic from a user equipment (“UE”). An observed time difference of arrival (“OTDOA”) hyperbola may then be calculated based on the first and second values, and a location of the unknown Node B as a function of the OTDOA hyperbola. Therefore, through the combination of a UE network measurement report characteristic and a downlink timing measurement from a location measurement unit, the location of an unknown Node B may be determined.

摘要： A system and method for estimating a location of wireless devices transmitting signals on channels in a communications system having a plurality of nodes and a plurality of Location Measurement Units (“LMU”). A first plurality of signals from a first channel may be received by one or more of the plural LMUs and a second plurality of signals from a second channel may be received by one or more of the plural LMUs. The received first and second plural signals may be converted into first and second digital signals and then divided into first and second sets of frequency bins, the first and second sets of bins corresponding to the respective channel. Each of the divided signals may be correlated with one or more reference signals, and the correlated signals stored in a database for estimating a location of one or more wireless devices.

摘要： A system and method for estimating a location of a wireless device in a wireless communication system having a plurality of nodes and a plurality of location measurement units (“LMUs”). A set of signal samples from a first wireless device and a second wireless device may be collected by one or more LMUs in a search window. A first time of arrival (“TOA”) is determined, and a second search window is estimated as a function of the first TOA. A second TOA may be determined within the second search window at a second node or one of the LMUs from the set of signal samples. A range estimate of the wireless device may then be determined, and an estimated location of the wireless device may be determined as a function of the first uplink TOA, the second uplink TOA, or the range estimate and second TOA.

摘要： 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 attributes of a received signal and based on these attributes the system determine whether the signal is served by a repeater or other network device.

摘要： A system and method for estimating a location of a wireless device receiving signals from plural nodes of a Universal Mobile Telecommunications System (“UMTS”) network. Observed time difference of arrival (“OTDOA”) measurements of signals received by the wireless device are collected and a message is transmitted to a stand alone serving mobile location center (“SAS”), the message including round trip time information, tipping information, and the collected OTDOA measurements. One or more location measurement units (“LMU”) are tasked to determine uplink and downlink signal measurements between the wireless device and ones of the plural nodes as a function of the transmitted message. At the one or more LMUs, range measurements from the wireless device to ones of the plural nodes, uplink time of arrival (“TOA”) measurements, and downlink TOA measurements are determined. A location of the wireless device may then be determined as a function of the uplink and downlink TOA measurements, OTDOA measurements, round trip time information, and range measurements.

摘要： A system and method for estimating a location of a wireless device receiving signals from plural nodes of a Worldwide Interoperability for Microwave Access (“WiMAX”) communication system. Contention or non-contention based ranging may be allocated to the wireless device, and a first signal may be transmitted from at least one of the plural nodes to the wireless device. Tipping information may then be transmitted to one or more location measurement units, and a ranging signal transmitted from the wireless device in response to the first signal. Uplink signal time of arrival measurements of the ranging signal may be performed as a function of the tipping information, and a location of the wireless device estimated as a function of the determined uplink measurements. Downlink signal measurements of first signals received by the wireless device from the plural nodes may also be determined and a location of the wireless device determined from the uplink and/or downlink measurements.
