Classification: CPC H  Y | IPC H

Claim 17:
18. A system comprising:
at least one hardware processor; and
software configured to, when executed by the at least one hardware processor, for each of a plurality of wireless devices,
synchronize one or more parameters defining an extended-sleep cycle at the wireless device with the wireless device, wherein each extended sleep cycle comprises an extended-sleep-ON duration, during which the wireless device monitors paging occasions transmitted over a wireless communication network, and an extended-sleep-OFF duration, during which the wireless device does not monitor the paging occasions;
receive a message to be transmitted to the wireless device,
based on the synchronized one or more parameters, determine a transmission time at which to transmit the message to the wireless device over the wireless communication network, such that the message will be received within the extended-sleep-ON duration of an extended-sleep cycle;
queue the message until the transmission time, and
at the transmission time, transmit the message over the wireless communication network to the wireless device,

wherein the synchronized one or more parameters for each of the plurality of wireless devices comprise a timing TB of the extended-sleep-cycle i of that wireless device, defined by:

TB(i)=T0+(exsSleepCycleLength*PCL*i)+(S*PCL),

wherein T0 is an offset of a universal time standard,
wherein exsSleepCycleLength is a duration of the extended-sleep cycle,
wherein PCL is a length of a paging cycle, and
wherein S is a parameter that is specific to the wireless device.
