    • A cellular radiotelephone system providing service to remote units having a voice operated transmitter (VOX) is disclosed. If the regularly scheduled periodic signal quality measurements made by fixed site equipment indicate that the remote unit signal has not been received for a predetermined number of measurements, an audit request is transmitted to the remote unit. The remote unit responsively keys its transmitter for a predetermined period of time. A first special scan is programmed into the regular process such that the fixed site equipment may continue with its regular process until the signal quality measurement must be made. A second measurement is made following the first and if the two signal quality measurements made while the VOX remote unit is known to be transmitting agree, system reconfiguration for the service of this remote unit may be implemented by the cellular system.
    • 公开了向具有语音操作发射机(VOX)的远程单元提供服务的蜂窝无线电话系统。 如果由固定现场设备进行的定期定期周期信号质量测量表明远程单元信号未被接收到预定数量的测量值,则向远程单元发送审核请求。 远程单元响应地将其发射机按压预定的时间段。 第一次特殊扫描被编程到常规过程中,使得固定位置设备可以继续其常规过程,直到必须进行信号质量测量。 在第一测量之后进行第二测量,并且如果在已知VOX远程单元被发送的情况下进行的两个信号质量测量一致,则该远程单元的服务的系统重新配置可以由蜂窝系统实现。
