    • 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 hearability of the signal at system receivers, the hearability 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.
    • 公开了一种在具有中继器的主机无线通信系统中操作的网络覆盖地理位置系统的新型系统和方法。 新颖的系统和方法的实施例使得无线通信系统能够确定系统接收器正在接收的信号是否直接从目标移动设备到达,或者信号是否通过中继器。 系统的确定可以至少部分地基于信号的TA,接收信号的功率,发射信号的功率,系统接收机处的信号的可听性,移动台处的系统发射机的可听性以及 与中继器相关的已知延迟。 新型系统和方法的实施例提供了比现有技术中能力更好的由中继站服务的移动台的地理定位。

    • A system and method for determining a location of a mobile device operating in a wireless communications network having an assisted global positioning system (A-GPS) positioning determining entity (PDE). A location request may be received for the mobile device. The location of the mobile device may be determined as a cell identification location if no location results are received from either the A-GPS PDE or a proximity detection system PDE, or the location of the mobile device may be determined as a location result from the A-GPS PDE if the A-GPS PDE provides a location result having a lower uncertainty than a location result from the proximity detection system PDE, or the location of the mobile device may be determined as a location result from the proximity detection system PDE if the proximity detection system PDE provides a location result having a lower uncertainty than a location result from the A-GPS PDE.
    • 一种用于确定在具有辅助全球定位系统(A-GPS)定位确定实体(PDE)的无线通信网络中操作的移动设备的位置的系统和方法。 可以为移动设备接收位置请求。 如果没有从A-GPS PDE或接近检测系统PDE接收到位置结果,则移动设备的位置可以被确定为小区标识位置,或者可以将移动设备的位置确定为来自 A-GPS PDE如果A-GPS PDE提供具有比来自接近检测系统PDE的位置结果更低的不确定性的位置结果,或者移动设备的位置可以被确定为来自接近检测系统PDE的位置结果,如果 接近检测系统PDE提供具有比来自A-GPS PDE的位置结果更低的不确定性的位置结果。
