Patent Images
1. A method for controlling a power state of a communications device, the method comprising:
- receiving over a network at a communications device in a low-power mode from a scheduling device an assignment of a power state schedule indicating one or more intervals to enter an active state period and one or more intervals to enter a sleep state period; and
during an active state period at the communications device, receiving over the network from a second communications device aware of the power state schedule a request that the communications device exit the low-power mode.

Abstract
Controlling a power state of a communications device includes: receiving over a network at a communications device in a low-power mode from a scheduling device an assignment of a power state schedule indicating one or more intervals to enter an active state period and one or more intervals to enter a sleep state period; and during an active state period at the communications device, receiving over the network from a second communications device aware of the power state schedule a request that the communications device exit the low-power mode.

19. A method for controlling a power state of a communications device, the method comprising:
-
receiving over a network at a communications device in a low-power mode from a scheduling device an indication of a power state schedule of a second communications device, the power state schedule indicating one or more intervals to enter an active state period and one or more intervals to enter a sleep state period; and during an active state period at the communications device, sending over the network to the second communications device, during an active state period indicated by the power state schedule, a request that the second communications device exit the low-power mode.

20. A network, comprising:
-
a scheduling device; and a communications device in communication with the scheduling device, configured to receive, in a low-power mode, an assignment of a power state schedule from the scheduling device, the power state schedule indicating one or more intervals to enter an active state period and one or more intervals to enter a sleep state period, and receive, during an active state period, a request that the communications device exit the low-power mode from a second communications device aware of the power state schedule.
