<p>Disclosed is a method and a system for conserving power. The method and system maintains continuous CDMA system time using a 32 kHz clock source. Specifically, one embodiment of the present invention includes a method for conserving power during a low power mode of a communication device while dynamically maintaining a Code Division Multiple Access (CDMA) system time. The method includes the step of causing a mobile station to enter a low power mode and utilizing a low power consuming inaccurate clock source (e.g., 32 kHz) to dynamically maintain a CDMA system time while limiting power input to a high power consuming accurate clock source, e.g., a Voltage Control Temperature Control Crystal Oscillator (VCTCXO). Furthermore, the method includes the step of utilizing an adjustment function to update a polynomial function (e.g., long PN) at a fixed increment which is part of the CDMA system time in order to minimize pilot signal acquisition time when the mobile station wakes up from the low power mode.</p> |
