    • 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。

    • A mobile communications network is provisioned to provide surveillance services. A subscriber database is adapted to include surveillance service information. For example, the subscriber database is adapted to include an IP address of a surveillance sensor such as a camera or microphone associated with a subscriber and located at a place to be monitored. A mobile switching center is adapted to determine a surveillance session start time, receive the surveillance sensor IP address from the subscriber database and connect to the surveillance sensor associated with the IP address. The MSC is also adapted to receive surveillance information from the surveillance sensor and transmit the surveillance information to a mobile communications device of the subscriber. The mobile communications device presents the surveillance information to the user. For example, images are displayed and/or audio signals are produced. The subscriber database can be provisioned by the subscriber through a web portal.
    • 提供移动通信网络来提供监控服务。 订户数据库适于包括监视服务信息。 例如,订户数据库适于包括监视传感器的IP地址,诸如与用户相关联的相机或麦克风,并位于要监视的地点。 移动交换中心适于确定监控会话开始时间,从用户数据库接收监视传感器IP地址并连接到与IP地址相关联的监视传感器。 MSC还适于从监视传感器接收监视信息,并将监视信息发送给用户的移动通信设备。 移动通信设备向用户呈现监视信息。 例如,显示图像和/或音频信号。 用户数据库可以由用户通过门户网站提供。
