Abstract
A method and system of reducing average power consumption in a wireless communication device (WCD) that operates in sleep and awake modes during monitoring of a slotted paging channel includes the steps of providing a plurality of counters; establishing a roll over point for each counter at a predetermined offset relative to each other counter; identifying a timing, point for at least one roll over point; and transitioning between the sleep and awake modes during the occurrence of an identified timing point.

A method of reducing average power consumption in a wireless communication device (WCD), the WCD operating in sleep and awake modes during monitoring of a slotted paging channel, comprising:
- providing a plurality of equal periods;
- establishing a roll over point for each counter at a predetermined offset relative to each other counter to establish substantially equal time increments around a pseudoniose (PN) sequence period between adjacent roll over points;
- identifying a timing point for at least one roll over point;
- and
- transitioning between the sleep and awake modes during the occurrence of an identified timing point.
A Wireless Communications Device (WCD) with reduced power consumption, the WCD operating in sleep and awake modes during monitoring of a slotted paging channel comprising:
- a plurality of counters of substantially equal periods, each counter having a roll over point at a predetermined offset relative to each other counter to establish substantially equal time increments around a pseudonoise (PN) sequence period between adjacent roll over points;
- a plurality of timing points that occur at the roll over times for the plurality of counters;
- and
- a controller that transitions the WCD between sleep and awake mode operation at the occurrence of one of the plurality of timing points.
A Wireless Communications Device (WCD) with reduced power consumption, the WCD open in sleep and awake modes during monitoring of a slotted paging channel, comprising:
- means for providing a plurality of counters of substantially equal periods;
- means for establishing a roll over point for each counter at a predetermined offset relative to each other counter to establish substantially equal time increments around a pseudonoise (PN) sequence period between adjacent roll over points;
- means for identifying a timing point for at least one roll over point;
- and
- means for transitioning between the sleep and awake modes during the occurrence of an identified timing point.
A computer program product comprising computer program logic for enabling a processor in a computer system to reduce average power consumption in a wireless communications device (WCD), the WCD operating in sleep and awake modes during monitor of a slotted pang channel, comprising:
- means for enabling the processor or to provide a plurality of counters of substantially equal periods;
- means for enabling the processor to establish a roll over point for each counter at a predetermined offset relative to each other counter to establish substantially equal time increments around a pseudonoise (PN) sequence period between adjacent roll over points;
- means for enabling the processor to identify a timing point for at least one roll over point;
- and
- means for enabling the processor to transition between the sleep and awake modes during the occurrence of an identified timing point.
