1. A host device that is configured to save energy through control of a sleep mode, the host device comprising:
- an interface configured toreceive, 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, andreceive, as an input, a sleep period indicating a duration that the see mode is to be maintained, and to provide the input sleep period to the proxy device by incorporating the sleep period into the proxy sleep request; and
a processor configured toextract, from a proxy sleep reply received from the proxy device in response to the proxy sleep request, information about whether the proxy sleep request is accepted by the proxy device,enter the sleep mode in response to the proxy sleep request being accepted,maintain the sleep mode for the duration of the sleep period, andswitch to a communication mode in response to the sleep period expiring or a wake-up request being received from the proxy device.

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.

5. 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 extract, from the proxy sleep request, a sleep period indicating a duration that the sleep mode is to be maintained, and determine whether to accept the proxy sleep request based on the requested sleep policy extracted from the proxy sleep request, and based on the sleep period; 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 (6, 7, 8, 9, 10, 11, 12, 13, 14)

15. A method of a host device that is configured to save energy through control of a sleep mode, the method comprising:
-
receiving, as an input, a requested sleep policy to be performed by a proxy device, and providing, to the proxy device, a proxy sleep request comprising the requested sleep policy; receiving, as an input, a sleep period indicating a duration that the sleep mode is to be maintained, and providing the input sleep period to the proxy device by incorporating the sleep period into the proxy sleep request; extracting, from a proxy sleep reply received from the proxy device in response to the proxy sleep request, information about whether the proxy sleep request is accepted by the proxy device, and entering the sleep mode in response to the proxy sleep request being accepted; and maintaining the sleep mode for the duration of the sleep period, and switching to a communication mode in response to the sleep period expiring or a wake-up request being received from the proxy device. - View Dependent Claims (16)

17. A method of a proxy device that is configured to save energy through control of a sleep mode, the method comprising:
-
extracting a requested sleep policy from a proxy sleep request that is received from a host device; extracting, from the proxy sleep request, a sleep period indicating a duration that the sleep mode is to be maintained; determining whether to accept the proxy sleep request based on the requested sleep policy extracted from the proxy sleep request, and based on the sleep period; and providing, to the host device, a proxy sleep reply including information about whether the proxy sleep request is accepted. - View Dependent Claims (18, 19)
