Managing power consumption in a wireless device
First Claim
Patent Images
1. A method of managing power consumption in a wireless communication device, said method comprising:
- monitoring a property of a wireless signal over time while maintaining a device in a first power state that utilizes less power than a second power state;
while said device remains in said first power state, comparing a measure of said property of said wireless signal to a first threshold and to a second threshold; and
transitioning said device from said first power state to said second power state if said measure crosses said first threshold and said second threshold, and otherwise maintaining said device in said first power state.

Abstract
A property of a wireless signal over time is monitored while a processor is maintained in a first power state that utilizes less power than a second power state. While the processor remains in the first power state, a measure of the property is compared to a first threshold and to a second threshold. The processor can be transitioned from the first power state to the second power state if the measure crosses the first threshold and the second threshold, and otherwise the processor is maintained in the first power state.

8. A method of managing power consumption in a wireless communication device, said method comprising:
-
monitoring a property of a wireless signal over time while maintaining a processor in a first power state that utilizes less power than a second power state; while said processor remains in said first power state, comparing a fluctuation of a measure of said property of said wireless signal to an acceptable range that has an upper limit and a lower limit; and transitioning said processor from said first power state to said second power state if said fluctuation increases or decreases beyond said acceptable range, and otherwise maintaining said processor in said first power state. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A system comprising:
-
a wireless communication device; and a processor coupled to said wireless communication device and having a first power state and a second power state, wherein said first power state utilizes less power than said second power state; wherein a property of a wireless signal is monitored over time with said processor in said first state, wherein a measure of said property of said wireless signal is compared to a first threshold and to a second threshold with said processor in said first power state, said processor transitioning from said first power state to said second power state if said measure crosses said first threshold and said second threshold, said processor otherwise remaining in said first power state. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
