REDUCED TERMINAL POWER CONSUMPTION VIA USE OF ACTIVE HOLD STATE
摘要:
An access terminal (AT) in a cellular communication system is configured to operate in an active hold (AH) state, a transitional state between traffic and dormant states. The AT applies power to its transmit chain with a low duty cycle while in the AH state, conserving battery power. To improve robustness of the communications, the radio network may power control the AT to a higher level relative to the power control level of the AT in the traffic state. Transition from the traffic state to the AH state may be initiated after a brief period of inactivity on the reverse link. The AT may remain in the AH state while receiving forward link payload data. Transmission of a reverse link payload packet in the AH state may initiate transition to the traffic state. A prolonged period of inactivity may initiate a transition from the AH state to the dormant state.
