Abstract

Disclosed is a method in which a machine-to-machine (M2M) device and a base station in a wireless communication system perform network reentry comprises the steps of: receiving, from a base station, information related to an uplink resource for the transmission of a ranging request message; and transmitting the ranging request message to the base station on the basis of the received information related to the uplink resource.

Claims

1. A method of performing a network reentry by an M2M (machine-to-machine) device in a wireless communication system, the method comprising:

receiving information related to an uplink resource for transmitting a ranging request message from a base station; and

transmitting the ranging request message based on the received information related to the uplink resource to the base station.

2. The method of claim 1, further comprising:

receiving a ranging response message including assigned uplink bandwidth information from the base station in response to the ranging request message, wherein the ranging request message includes a bandwidth request indicator.

3. The method of claim 1, wherein the information related to the uplink resource is transmitted through a paging message.

4. The method of claim 3, wherein the information related to the uplink resource comprises information regarding to a transmission timing of control information including uplink resource information allocated for a ranging request transmission.

5. The method of claim 3, wherein the information related to the uplink resource comprises information indicating the uplink resource allocated for a ranging request transmission and wherein the ranging request message is transmitted to the base station through the indicated uplink resource.

6. The method of claim 4, wherein the control information corresponds to CDMA Allocation A-MAP IE message type.

7. The method of claim 3, wherein the uplink resource is a dedicated resource for the M2M device.

8. The method of claim 1, wherein the M2M device is a fixed M2M device.

9. An M2M (machine to machine) device for performing a network reentry in a wireless communication system, the M2M device comprising:

a receiver configured to receive an information related to an uplink resource for transmitting a ranging request message from a base station; and

a transmitter configured to transmit the ranging request message based on the received information related to the uplink resource to the base station.

10. The M2M device of claim 9, wherein the receiver receives a ranging response message including an assigned uplink bandwidth information from the base station in response to the ranging request message and wherein the ranging request message includes a bandwidth request indicator.

11. The M2M device of claim 9, wherein the information related to the uplink resource is transmitted through a paging message.

12. The M2M device of claim 11, wherein the information related to the uplink resource comprises information regarding a transmission timing of control information including uplink resource information allocated for a ranging request transmission.

13. The M2M device of claim 11, wherein the information related to the uplink resource comprises information indicating the uplink resource allocated for a ranging request transmission and wherein the transmitter transmits the ranging request message to the base station via the indicated uplink resource.

14. The M2M device of claim 12, wherein the control information corresponds to CDMA Allocation A-MAP IE message type.

15. The M2M device of claim 11, wherein the uplink resource is a dedicated resource for the M2M device.

16. The M2M device of claim 9, wherein the M2M device is a fixed M2M device.

17. A method of performing a network reentry by a base station with an M2M (machine-to-machine) device in a wireless communication system, the method comprising:

transmitting information related to an uplink resource for transmitting a ranging request message to the M2M device; and

receiving the ranging request message based on the received information related to the uplink resource from the M2M device.

18. The method of claim 17, further comprising:

transmitting a ranging response message including an assigned uplink bandwidth information to the M2M device in response to the ranging request message, wherein the ranging request message includes a bandwidth request indicator.

19. A base station for performing a network reentry with an M2M (machine-to-machine) device in a wireless communication system, the base station comprising:

a transmitter configured to transmit an information related to an uplink resource for transmitting a ranging request message to the M2M device; and

a receiver configured to receive the ranging request message based on the received information related to the uplink resource from the M2M device.

20. The method of claim 19, wherein the transmitter transmits a ranging response message including assigned uplink bandwidth information to the M2M device in response to the ranging request message, wherein the ranging request message includes a bandwidth request indicator.
