Motion status states reported by an advanced motion detection process or other means of obtaining a movement state of Stationary or Non-Stationary from filtered accelerometer data are utilized to reacquire service during Out of Service scenarios. Both movement states operate in three power phases: aggressive scanning or normal power mode, slow scanning or moderate power mode, and deep sleep or power saving mode. The scanning rate, power mode, scanning period and/or channel list depend upon the movement state and power phase. Motion information obtained from an advanced motion detection process provides substantial improvements in service reacquisition performance and power consumption in stationary Out of Service scenarios. When compared to traditional service reacquisition scanning routines, the reductions in average current can be achieved of: at a 5-minute OOS mark, ˜45% reduction, at a 15-minute OOS mark, ˜60% reduction and at a 6-hour OOS mark, ˜50% reduction.
