摘要： A method and apparatus whereby a remote unit (10A, 10B and 10C) in a slotted mode wireless communication system may calculate accurate time throughout its entire active state. In the remote unit (10A, 10B and 10C) a 'wall clock time' is calculated from a modulo 80 counter called a combiner time counter (224). When a remote unit (10A, 10B and 10C) enters its inactive state, counters within the remote unit (10A, 10B and 10C), including the combined time counter, are deactivated. When the remote unit (10A, 10B and 10C) reenters its active state, the value in the combiner time counter (224) may not be correct in relationship to slotted mode time. A controller (106) in the remote unit (10A, 10B and 10C) forces the combiner time counted to the correct phase resulting in the combiner (224) being within 26.66 of the correct value. The controller (106) then determines a combiner offset to compensate for any remaining error in the combiner time counter (224). The control (106) may then use the combiner time counter (224) and the combiner offset to calculate accurate wall clock time. When convenient, such as at a slot boundary, the remote unit (10A, 10B and 10C) may reset the combiner counter (224) to a correct value, and set combiner offset to zero.

摘要： A quick paging channel (QPCH) is used to receive paging indicators that indicate that a wireless communication device (WCD) has a message on a paging channel relating to, for example, an incoming call to the WCD. When the condition of the quick paging channel is too low to receive paging indicators reliably, the quick paging channel is disabled to avoid false alarms, and the slotted paging channel is used to receive paging messages without monitoring the QPCH. When the QPCH signal is strong, the probability of false alarms is lower, and the quick paging channel is enabled. By using the quick paging channel to receive paging indicators only when the QPCH signal is strong, the wireless communication device can remain in a sleep state for greater periods of time as compared with the use of a slotted paging channel. As a result, standby time may be significantly improved.
摘要翻译：快速寻呼信道（QPCH）用于接收指示无线通信设备（WCD）在寻呼信道上具有与例如对WCD的呼入有关的消息的寻呼指示符。当快速寻呼信道的条件太低而不能可靠地接收寻呼指示时，快速寻呼信道被禁用以避免虚假告警，并且时隙寻呼信道用于接收寻呼消息而不监控QPCH。当QPCH信号强时，虚警告的概率较低，快速寻呼信道被使能。通过使用快速寻呼信道仅在QPCH信号强时接收寻呼指示符，与使用时隙寻呼信道相比，无线通信设备可以保持更长时间的睡眠状态。结果，可以显着提高待机时间。

摘要： A mobile station selectively operates in quick paging mode (108) or in slotted paging mode (110). If the quality of the channel exceeds a threshold (106), then the mobile station operated in quick paging mode; otherwise in slotted paging mode. The mobile station measures channel quality by measuring various quality metrics (112-120) made during several previous pages (124), preferably over a period of about ten seconds (128). The quality metrics, and the previous pages, are preferably all given equal weight (122, 126).
