Fast reacquisition after long sleep
First Claim
Patent Images
1. A mobile station comprising:
- a receiver for receiving a first plurality of signals from a first base station operating in a voice network and a second plurality of signals from a second base station operating in a data network; and
a processor which controls the receiver and analyzes the second plurality of signals, the processor configured to activate the receiver prior to a paging slot and determine if a handoff in the data network is desired, wherein the processor deactivates the receiver prior to the paging slot if no handoff is desired.

Abstract
The mobile station is in the sleep mode until just prior to a designated slot. Upon wakeup, the mobile station ensures a link is maintained with the network by measuring the strength of several pilots. If a neighbor pilot is stronger than the current pilot, a handoff is performed. After handoff, the Control Channel Capsule (CCC) may be demodulated by the mobile station to obtain new overhead information, such as neighbor pilots. If no handoff is performed, the reacquisition slew for the current pilot is measured and fed back to the sleep controller to determine the next wake-up time. The mobile station then returns to sleep mode.
