    • Methods are disclosed for detecting and recovering from incidents of wireless signal interference that threaten to disable or disrupt wireless telephone services. Mobile units that are engaged in active calls that are compromised due to incidents of wireless signal interference are instructed to retune to an alternate channel. If the mobile successfully receives the retune message, it performs a handoff to the alternate channel and the call remains active. Otherwise, the call will be dropped or suspended. For a period of time following incidents of interference, affected channels are rendered unavailable for new call originations, terminations, handoffs or reconnects; however, the channels may be redesignated as available if sufficient time elapses without any further incidents of wireless signal interference.
    • 公开了用于检测和恢复威胁禁用或中断无线电话服务的无线信号干扰事件的方法。 指示由于无线信号干扰的事件而入侵的活动呼叫的移动单元重新调谐到备用信道。 如果移动设备成功接收到重新调谐消息,它将执行到备用频道的切换,并且呼叫保持活动状态。 否则,呼叫将被丢弃或暂停。 在干扰事件发生一段时间后,受影响的频道不可用于新的呼叫发起,终止,切换或重新连接; 然而,如果足够的时间经过而没有任何进一步的无线信号干扰的事件,信道可被重新指定为可用。
