DEVICES AND METHODS FOR SAVING ENERGY THROUGH CONTROL OF SLEEP MODE
First Claim
Patent Images
1. A host device that is configured to save energy through control of a sleep mode, the host device comprising:
- an interface configured to receive, as an input, a requested sleep policy to be performed by a proxy device, and to provide, to the proxy device, a proxy sleep request comprising the requested sleep policy; and
a processor configured to extract, from a proxy sleep reply, information about whether the proxy sleep request is accepted by the proxy device, and to enter the sleep mode if the proxy sleep request is accepted.

Abstract
A system for saving energy through control of a sleep mode, and a method of operating the system are provided. The energy-saving system may enable a proxy device to maintain a minimum basic setup necessary for a communication when a host device enters a sleep mode, and may omit an operation performed based on the basic setup when the host device switches to a communication mode, thereby enabling a smooth switch between the sleep mode and the communication mode.

4. A proxy device that is configured to save energy through control of a sleep mode, the proxy device comprising:
-
a determination unit configured to extract a requested sleep policy from a proxy sleep request received from a host device, and to determine whether to accept the proxy sleep request based on at least one of the requested sleep policy extracted from the proxy sleep request and an available capacity of a cache; and a controller configured to provide, to the host device, a proxy sleep reply comprising information about whether the proxy sleep request is accepted. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13)
