    • Systems and methods of this disclosure can operate to re-synchronize timing between communication devices and can include a timing server. The timing server can provide timing messages containing timing correction values to communication devices that can synchronize the communication devices. If communication devices fail to receive timing messages, the communication devices may continue to provide communication services using their internal clocks that can drift over time. When timing messages are restored, the timing correction values can be significant enough to result in the loss of communications if immediately applied by communication devices. By gradually applying timing corrections over a period of time approaching the received timing correction value, communication devices can achieve re-synchronization while avoiding and/or minimizing the loss of communications.
    • 本公开的系统和方法可以操作以重新同步通信设备之间的定时,并且可以包括定时服务器。 定时服务器可以向可以同步通信设备的通信设备提供包含定时校正值的定时消息。 如果通信设备不能接收定时消息,则通信设备可以使用其随时间漂移的内部时钟来继续提供通信服务。 当定时消息被恢复时,如果通信设备立即应用,定时校正值可能足够大以导致通信丢失。 通过在接近定时校正值的时间段内逐渐应用定时校正,通信设备可以实现重新同步,同时避免和/或最小化通信丢失。
