摘要： In a radio frequency (RF) receiver, a receiver RF chain is tuned to a first (e.g., global positioning system (GPS)) channel to permit receipt of a first (e.g., GPS) signal over the first (e.g., GPS) channel on the receiver RF chain during a first time duration. The receiver RF chain is tuned to a second (e.g., cellular page) channel to permit receipt of a second (e.g., cellular page) signal over the second (e.g., cellular page) channel on the receiver RF chain during a second time duration, following the first time duration. The first (e.g., GPS) signal is processed during the first time duration and the second time duration, without any apparent interruption of the first (e.g., GPS) signal during the second time duration. The processing, for example, treats the actual interruption as a temporary, short term fade of the first (e.g., GPS) signal during the second time duration, or provides a bridge signal (e.g., an estimated GPS signal on the receiver RF chain or an actual GPS signal received on another receiver RF chain) during the second time duration.
摘要翻译：在射频（RF）接收机中，接收器RF链被调谐到第一（例如，全球定位系统（GPS））信道，以允许在第一（例如，GPS）信道上接收第一（例如，GPS）信号在第一时间段内在接收机RF链上。接收机RF链被调谐到第二（例如，蜂窝页）信道，以允许在第二持续时间期间在接收机RF链上的第二（例如，蜂窝页）信道上接收第二（例如，蜂窝页）信号，按照第一次持续时间。在第一持续时间和第二持续时间期间处理第一（例如，GPS）信号，而在第二持续时间期间没有第一（例如，GPS）信号的明显中断。例如，该处理将实际中断视为在第二持续时间期间第一（例如，GPS）信号的临时短期衰落，或提供桥接信号（例如，接收机RF链上的估计的GPS信号或在另一个接收机RF链上接收的实际GPS信号）。

摘要： A method performs an update for a first device that consumes information with a known expiration time. The first device operates within a network that accommodates other devices also consuming the information. The method includes setting a time for the first device to refresh the information, the time to refresh being based on a pseudorandom time offset. The method also includes sending a refresh request to a resource for the data during the set time.
