    • A system and method for effectively performing enhanced device location procedures to determine the current physical location of a mobile device includes a plurality of satellites that wirelessly transmit satellite beacon signals, a plurality of base stations that wirelessly transmit pilot signals, and a plurality of access points that wirelessly transmit access-point beacon signals. A location detector of the mobile device coordinates a device location procedure by measuring the satellite beacon signals, the pilot signals, and the access-point beacon signals to generate corresponding satellite information, base station information, and access point information. The location detector analyzes the satellite information, the base station information, and the access point information to select an optimal system configuration from the most effective satellites, base stations, and access points. The location detector then utilizes the optimal system configuration to accurately calculate the current physical location of the mobile device.
    • 用于有效执行增强的设备定位过程以确定移动设备的当前物理位置的系统和方法包括:无线发射卫星信标信号的多个卫星,无线发射导频信号的多个基站以及多个接入点 无线发送接入点信标信号。 移动设备的位置检测器通过测量卫星信标信号,导频信号和接入点信标信号来协调设备定位过程,以产生对应的卫星信息,基站信息和接入点信息。 位置检测器分析卫星信息,基站信息和接入点信息,以从最有效的卫星,基站和接入点中选择最佳系统配置。 然后,位置检测器利用最佳系统配置来精确地计算移动设备的当前物理位置。
