摘要： A system for measuring a rise-over-thermal (RoT) characteristic in a communication network includes controlling a transmitting station to maintain its transmit power at a substantially constant level for a first time interval, and measuring a first received power level. The transmitting station is then controlled to adjust its transmit power by a selectable amount for a second time interval, and a second received power level is measured. The first and second received power levels are then processed to determine the RoT characteristic.

摘要： Interoperability between wireless communication systems, such as the IS2000-1x and IS856 systems, is facilitated by using supervision timers. A wireless communication device starts one or more supervision timers and performs an intersystem transition. When the wireless communication device returns from the transition, the supervision timers are used to estimate the duration of the transition. The wireless communication device then performs a sequence of tasks appropriate to the estimated duration.

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无法可靠地接收寻呼指示时，快速寻呼信道被禁止，以避免误报，而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，误报的概率较低，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较长时间的睡眠状态。结果，可以显着提高待机时间。

摘要： A wireless communication device performance, such as standby time, is improved by adaptively allocating surplus system resources to change quick paging channel parameters at the system, such a system being for example, a base station. Adaptively adjusting the quick paging channel parameters allows available base station resources to be allocated to the quick paging channel, thereby enabling the wireless communication device to demodulate the quick paging channel more reliably. Parameters such as the number of quick paging channels, the data rate used by the paging channel, and the quick paging channel transmit power level are weighed and adjusted.
