Method of power conservation in a data communications system
First Claim
1. In a communications apparatus, a method comprising:
- monitoring a data channel during an active time period;
determining a channel quality value for the data channel during at least a portion of said active time period;
upon completion of the active time period comparing said channel quality value to a first threshold;
entering a sleep state when said channel quality value satisfies said first threshold; and
scanning another data channel for another channel quality value that satisfies a second threshold when said channel quality value does not satisfy said first threshold.

Abstract
In a data communications system including an infrastructure and a subscriber unit operating with a protocol that mandates proactive scanning, a method of power conservation practiced at the subscriber unit including monitoring a registered data channel during an active time period (403), assessing the data channel during the active time period to provide a channel quality value (407), comparing the channel quality to a first threshold (413), assuming a sleep state when the channel quality satisfies the first threshold (417), and scanning another data channel for another channel quality value that satisfies a second threshold when the channel quality does not satisfy the first threshold (415).

8. A communications apparatus, comprising:
-
means for waking a portion of the communications apparatus up from an inactive time period; means for monitoring a data channel during an active time period; means for determining a channel quality value for the data channel during at least a portion of said active time period, and upon completion of the active time period, comparing said channel quality value to a first threshold; wherein the means for waking up is further operable for causing said portion of the communications apparatus to enter a sleep state when said channel quality value satisfies said first threshold; and wherein the means for determining is further operable for scanning another data channel for another channel quality value that satisfies a second threshold when said channel quality value does not satisfy said first threshold, and then controlling said means for waking to cause said portion of the communications apparatus to enter the sleep state. - View Dependent Claims (9, 10, 11, 12, 13, 14)
