摘要： Methods, devices and computer program products are disclosed that allow for wireless communication devices to operate more robustly in the slotted mode of operation in the event of network system loss. Specifically, present aspects require the wireless device to move to or remain in the slotted mode of operation as opposed to immediately entering into a system determination/acquisition mode upon failing to acquire an active set pilot during a slotted wake-up. By moving to the slotted mode of operation or providing for additional slotted-wake-ups, a number of attempts at acquiring the active set pilot can be performed before declaring the system as lost, thereby allowing for fading channel conditions to prevail without the need to re-acquire the lost system or otherwise acquire another system. Since the performance of the slotted mode is less power intensive than acquiring or re-acquiring a system, a substantial power savings is realized.

摘要： A wireless device detects for an adverse channel condition, which may be (1) a frequent out of service (FOOS) condition indicative of frequent in and out of service or (2) an unbalanced forward/reverse link condition indicative of unbalanced coverage for the forward and reverse links. A FOOS condition may be detected based on an average in-service time, the number of lost system connections, the number of systems to which connections have been made, the rate of change for the systems, the altitude of the wireless device, and/or other parameters. An unbalanced forward/reverse link condition may be detected based on the average in-service time, the number of system access failures, and/or other parameters. The wireless device performs at least one action to conserve battery power if an adverse channel condition is detected. The action(s) may include performing system acquisition less frequently, disabling system registration, performing registration less frequently, and/or going to sleep.

摘要： The standby time of a CDMA cell phone is extended by using two receive chains to monitor the Quick Paging Channel (QPCH) when the signal-to-noise ratio falls within a predetermined range. Monitoring the QPCH saves battery power by obviating the need to monitor the general paging message unless quick paging (PI) bits are set. The QPCH is not monitored, however, in noisy environments where PI bits are incorrectly detected causing the paging message to be needlessly monitored. Power is saved by monitoring the QPCH in noisier environments without increasing the incorrect detection rate. Incorrect detection is reduced in the predetermined range by using an additional receive chain to achieve receive diversity. Although additional power is consumed by the second receive chain in the predetermined range, the power saved by not demodulating the paging message at each slot more than compensates for the additional power consumed by the second receive chain.
摘要翻译： 当信号噪声比落在预定范围内时，通过使用两个接收链来监视CDMA蜂窝电话的待机时间来监视快速寻呼信道（QPCH）。 除非快速寻呼（PI）位被设置，否则监视QPCH可以通过消除监视通用寻呼消息的需要来节省电池电量。 然而，在不正确检测到PI位导致寻呼消息被不必要地监视的嘈杂环境中，QPCH不被监视。 通过在嘈杂的环境中监视QPCH来节省功耗，而不会增加错误的检测率。 通过使用额外的接收链来实现接收分集，在预定范围内减少了不正确的检测。 虽然第二接收链在预定范围内消耗额外的功率，但是通过不解调每个时隙处的寻呼消息所节省的功率多于补偿第二接收链消耗的附加功率。

摘要： Apparatus and methods are disclosed for power optimization in a wireless device. The apparatus and methods effect monitoring the amount of data stored in a data buffer that buffers data input to and data output from a processor. Dependent on the amount of data stored in the buffers parameters of a control function, such as a Dynamic Clock and Voltage Scaling (DCVS) function are modified based on the amount of data stored in the data buffer. By modifying or pre-empting the parameters of the control function, which controls at least processor frequency, the processor can process applications more dynamically over default parameter settings, especially in situations where one or more real-time activities having strict time constraints for completion are being handled by the processor as evinced by increased buffer depth. As a result, power usage is further optimized as the control function is more responsive to processing conditions.

摘要： Techniques for dynamically selecting warm-up time for a wireless device operating in the idle mode are described. At each active interval, conditions affecting warm-up of the wireless device at a next active interval are determined. The conditions may pertain to channel conditions, operating conditions, and/or hardware configuration. A warm-up time is selected based on the determined conditions. A wake-up time for the next active interval is determined based on the selected warm-up time. The wireless device then goes to sleep until the wake-up time. In one scheme, the strongest pilot acquired in each active interval is identified, and its pilot strength is averaged to obtain an average pilot strength. The average pilot strength is compared against at least one threshold, and one of at least two possible time durations is selected for the warm-up time based on the comparison result.

摘要： A channel scanning order is dynamically created, modified, selectively ignored, or combinations thereof based on historical data, motion information, context information, alert message systems, network reselection, or combinations thereof. If a less preferred network has served a mobile device longer than a threshold amount of time, acquisition of the less preferred network is attempted before attempting acquisition of a more preferred network.
