More particularly, the method comprises the steps of: transmitting a message including a dedicated connection identifier (CID) dedicatedly allocated to a device that supports machine to machine communication; allocating a dedicated ranging area for transmission of a ranging request message to the device that supports machine to machine communication; and transmitting an uplink map (UL-MAP) message including information on the dedicated CID and the dedicated ranging area to the device that supports machine to machine communication. ## Claims ### Claim 1 A method of assigning a ranging channel in a wireless communication system supporting a machine to machine communication, the method comprising: transmitting a message including a dedicated connection identifier (CID) dedicatedly allocated to a device supporting the machine to machine communication; allocating a dedicated ranging region to the device supporting the machine to machine communication to transmit a ranging request message; and transmitting an uplink MAP (UL-MAP) message including information on the dedicated CID and the dedicated ranging region to the device supporting the machine to machine communication. ### Claim 2 (depends on 1) The method of claim 1, wherein the message including the dedicated CID corresponds to an uplink channel descriptor message or a downlink channel descriptor message. ### Claim 3 (depends on 1) The method of claim 1, wherein the message including the dedicated CID corresponds to a registration response message. ### Claim 4 (depends on 1) The method of claim 1, wherein the message including the dedicated CID corresponds to a de-registration response message. ### Claim 5 (depends on 1) The method of claim 1, wherein the message including the dedicated CID corresponds to a dynamic service addition request message or a dynamic service addition response message. ### Claim 6 (depends on 1) The method of claim 1, wherein the dedicated ranging region is differently allocated according to a group including one or more devices supporting the machine to machine communication. ### Claim 7 (depends on 1) The method of claim 1, further comprising transmitting a message including a dedicated ranging region indicator, wherein the dedicated ranging region indicator indicates whether the device supporting the machine to machine communication uses a ranging region allocated by the UL-MAP message including a broadcast CID. ### Claim 8 A base station assigning a ranging channel in a wireless communication system supporting a machine to machine communication, the base station comprising: an RF (radio frequency) unit configured to transceive a radio signal; and a processor configured to transmit a message including a dedicated connection identifier (CID) dedicatedly allocated to a device supporting the machine to machine communication, the processor configured to allocate a dedicated ranging region to the device supporting the machine to machine communication to transmit a ranging request message, and the processor configured to transmit an uplink MAP (UL-MAP) message including information on the dedicated CID and the dedicated ranging region to the device supporting the machine to machine communication. ### Claim 9 (depends on 8) The base station of claim 8, wherein the message including the dedicated CID corresponds to an uplink channel descriptor message or a downlink channel descriptor message. ### Claim 10 (depends on 8) The base station of claim 8, wherein the message including the dedicated CID corresponds to a registration response message. ### Claim 11 (depends on 8) The base station of claim 8, wherein the message including the dedicated CID corresponds to a de-registration response message. ### Claim 12 (depends on 8) The base station of claim 8, wherein the message including the dedicated CID corresponds to a dynamic service addition request message or a dynamic service addition response message. ### Claim 13 (depends on 8) The base station of claim 8, wherein the dedicated ranging region is differently allocated according to a group including one or more devices supporting the machine to machine communication. ### Claim 14 (depends on 8) The base station of claim 8, further comprising transmitting a message including a dedicated ranging region indicator, wherein the dedicated ranging region indicator indicates whether the device supporting the machine to machine communication uses a ranging region allocated by the UL-MAP message including a broadcast CID.
