1. A method of supporting sleep mode of a mobile station (MS) in a broadband wireless access system, the method comprising:
- receiving, from a MS network control management system (NCMS), a first primitive that indicates a sleep request;
sending, to the MS NCMS, a second primitive that indicates a sleep confirmation after sending, to a network, a sleep request message and receiving, from the network, a sleep response message;
sending, to the MS NCMS, a third primitive that indicates whether there is traffic or not, in response to receiving, from the network, a traffic indication message;
receiving, from the MS NCMS, a fourth primitive that indicates a sleep start request; and
sending, to the MS NCMS, a fifth primitive that indicates a result of the sleep start request, wherein the result indicates success or failure of the sleep start request,wherein the fourth primitive comprises an action code, the action code indicating maintain normal status or start sleep status.

Abstract
The primitives between an upper management layer and the MAC layer within a mobile station and a base station are defined in order to specify and clarify the operations within the protocol stack layers in a broadband wireless access system to allow a mobile station to perform sleep mode. Media Independent Handover (MIH) procedures can be achieved because the NCMS and MIH layer can communicate through use of these primitives.

6. A method of supporting sleep mode of a mobile station (MS) in a broadband wireless access system, the method comprising:
-
establishing a unified interface media independent handover (MIH) to an upper layer of the MS for managing messages to and from at least one of a homogeneous network and a heterogeneous network; sending, to a MS network control management system (NCMS), a first message that allows the unified interface MIH to request a MS MAC to initiate sleep mode; receiving, from a MS MAC, a second message that indicates confirmation of the initiated sleep mode; and receiving, from the MS MAC, a third message that indicates whether there is traffic or not; sending, to the MS NCMS, a fourth message that indicates a sleep start request; and receiving, from the MS NCMS, a fifth message that indicates a result of the sleep start request, wherein the result indicates success or failure of the sleep start request. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A method of supporting sleep mode of a mobile station in a broadband wireless access system, the method comprising:
-
sending, to a network control management system (NCMS) or upper entity, a first primitive that indicates a sleep request after receiving, from a MS MAC, a sleep request message; receiving, from the network NCMS or upper entity, a second primitive that indicates a result of the sleep request; and sending, to the MS MAC, a sleep response message. - View Dependent Claims (14, 15, 16)
