    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.

    摘要： Embodiments disclosed herein relate to methods and systems for providing adaptive server selection in wireless communications. An access terminal may be configured to determine a forward link quality metric associated with each of a plurality of sectors serviced by a plurality of access points; assign credits to each sector in relation to the forward link quality metric; and change a data source control (DSC) value if the credits accumulated for a non-serving sector at a DSC change boundary is greater than a predetermined threshold, where the non-serving sector and the serving sector for the access terminal belong to different cells. The access terminal may be further configured to change a data rate control (DRC) cover in accordance with the DSC change. The use of DSC may provide an early indication of handoff, thereby allowing the service outage associated with server switching to be substantially reduced.
