    • A system for locating a mobile wireless device is configured to communicate with a wireless communications system via a control plane and a user plane. The user plane includes a data channel, and the system includes a server configured to communicate via the data channel with a wireless device to be located. The server obtains from the wireless device information useful for tasking the wireless location system. The information useful for tasking may include information indicative of at least one cell site neighboring a serving cell site with which the wireless device is communicating. This may include information indicative of a serving cell site, a reverse channel through which the wireless device is communicating, and/or a hopping pattern, etc. The system may be used, for example, in connection with a GSM or UMTS wireless communications system.

    • Mobile LMUs can be used in a Wireless Location System to provide detection coverage in areas lacking adequate receiver coverage. The mobile LMUs can be used to detect the radio frequency (RF) transmissions from wireless handsets and devices over a period of time to permit determination of their location. The mobile LMU' s time, position, and velocity is calculated and transmitted to a SMLC along with any transmissions received from wireless devices. The SMLC analyzes and resolves the Doppler component of the wireless device while compensating for the Doppler component of the mobile LMU. The position and velocity of the wireless device can be compared with real-time imagery taken by the mobile LMU platform to accurately determine the location of the wireless device. To enhance the mobile LMU' s ability to detect a signal of interest, which may be very weak and/or corrupted by noise, a process may be employed whereby the low power mobile terminals' signals are received at receiving sites and stored in memory. Then, a more powerful replica of the SOI is received at a later time from a network controller, or BTS, and this is employed to enhance the correlation processing of the SOI in memory.
    • 移动LMU可用于无线定位系统,以在缺乏足够的接收机覆盖的区域提供检测覆盖。 移动LMU可用于在一段时间内检测来自无线手机和设备的射频(RF)传输,以允许确定其位置。 计算移动LMU的时间,位置和速度并将其发送到SMLC以及从无线设备接收的任何传输。 SMLC分析和解决无线设备的多普勒分量,同时补偿移动LMU的多普勒分量。 无线设备的位置和速度可以与移动LMU平台拍摄的实时图像进行比较,以准确地确定无线设备的位置。 为了增强移动LMU检测感兴趣的信号的能力,其可能非常弱和/或被噪声破坏,可以采用这样的过程,由此在接收站点接收低功率移动终端的信号并将其存储在存储器中。 然后,在后来从网络控制器或BTS接收更强大的SOI复制品,并且这被用于增强存储器中的SOI的相关处理。
