    摘要： The disclosure is directed to a mobile communication device that may receive wireless broadcast signals from a number of different base stations or transmitters. The device alternates its operation between a low-power mode and a higher-power mode to conserve battery power. The length of time the device remains in the sleep mode is its sleep interval. The sleep interval is a function of two components. One component is set by the wireless broadcast network and the other component is set by the carrier that provisions the mobile communications device. When the device awakens from the sleep mode, it can check the status of any notification messages. If there are any updates, then it will process them. If there are no updates, then it will return to the low-power mode.

    摘要翻译： 本公开针对可从多个不同基站或发射机接收无线广播信号的移动通信设备。 该设备在低功耗模式和高功率模式之间交替运行，以节省电池电量。 设备保持睡眠模式的时间长度是其睡眠间隔。 睡眠间隔是两个组件的函数。 一个组件由无线广播网络设置，另一个组件由提供移动通信设备的运营商设置。 当设备从睡眠模式唤醒时，它可以检查任何通知消息的状态。 如果有任何更新，那么它将处理它们。 如果没有更新，那么它将返回到低功耗模式。

    摘要： Methods and apparatus to optimize delivery of multicast content using probabilistic feedback. A method is provided for transmitting data from a server to a plurality of receiving terminals. The method includes transmitting the data from the server to the plurality of receiving terminals, and generating a random response value at each receiving terminal. The method also includes comparing the response value to an acknowledgement value at each receiving terminal, and transmitting an acknowledgment signal to the server from selected receiving terminals. The selected receiving terminals are a portion of the plurality of receiving terminals where the response value has a selected relationship to the acknowledgement value.
