    • In a method for a terminal to measure a location by using a public safety monitoring system, when a public safety mode available for tracking a location while a terminal is turned off is set, the terminal acquires location measurement information and transmits it to the public safety monitoring system. In a method for measuring a location of a terminal to which plural stages of public safety modes are set, when a stage for performing a location measurement process is set, the terminal acquires location measurement information, transmits location measurement information to the public safety monitoring system, and enters the next stage when the public safety mode is not cancelled after a predetermined time. In a method for measuring a location of a terminal in a public safety monitoring system, a public safety mode setting request message including control information is transmitted to the terminal to which a public safety mode setting is requested, location measurement information is received from the terminal, and the location of the terminal is tracked.
    • 在终端通过使用公共安全监控系统测量位置的方法中,当设置在终端被关闭时可用于跟踪位置的公共安全模式时,终端获取位置测量信息并将其发送到公共安全 监视系统。 在设置多级公共安全模式的终端的位置测定方法中,当设置用于进行位置测量处理的阶段时,终端取得位置测量信息,将位置测量信息发送到公共安全监控系统 并且在公共安全模式在预定时间之后未被取消时进入下一阶段。 在公共安全监控系统中测定终端的位置的方法中,将包含控制信息的公共安全模式设定请求消息发送到请求公共安全模式的终端,从终端接收位置测量信息 ,并跟踪终端的位置。

    • A wireless positioning method of a receiver is provided. Signals are received from a plurality of transmitters, propagation taps of the plurality of transmitters received from the plurality of transmitters are determined, respectively, the distance between the receiver and each of the transmitters is calculated, respectively, the weight of each of the transmitters is calculated by using each of the propagation delay tap, the distance is adjusted by using the weight of each of the transmitters, and an area, in which circles away by the adjusted distances between the receiver and each of the transmitters on the basis of each of the transmitters overlap with each other, is estimated as the location of the receiver. Thus, an error of wireless positioning according to a propagation environment can be reduced.
    • 提供了一种接收机的无线定位方法。 从多个发射机接收信号,分别确定从多个发射机接收的多个发射机的传播抽头,分别计算接收机与每个发射机之间的距离,每个发射机的权重分别为 通过使用每个传播延迟抽头计算出的距离,通过使用每个发射机的权重以及基于接收机和每个发射机之间的调整距离的圆距离来调整距离 发射机彼此重叠,被估计为接收机的位置。 因此,可以减少根据传播环境的无线定位的错误。
