20130090117 | METHOD AND APPARATUS FOR OPTIMIZED REACQUISITION OF WIRELESS COMMUNICATIONS SYSTEMS - 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. | 04-11-2013 |
20130090151 | METHOD AND APPARATUS FOR ADVANCED MOTION DETECTION IN WIRELESS COMMUNICATIONS SYSTEMS - Advanced Motion Detection in Wireless Communication Systems processes accelerometer or other sensor input data to distinguish between random in-place movements and actual start of motion that could produce a change in the user's location by filtering unsustained random motion. Random in-place motion such as table banging, knee jiggling, vibration, etc. are filtered out from Stationary and Non-Stationary motion state determinations. The process utilizes data from motion sensors or any accelerometer standard in all smart mobile devices and any mobile device that has automatic portrait-landscape switching (screen rotation). A state machine processes sensor or other input to produce a filtered Stationary or Non-Stationary output movement state unaffected by transient motion or rest periods. A sensor processing subsystem (SPS), or other low power processor for processing sensor or other input may be implemented to reduce power consumption and processing overhead while, for example, a modem processor or other high power processor is in a sleep mode. | 04-11-2013 |
