Abstract

Provided are an operation method for M2M (machine to machine) communication and a device using same. M2M equipment receives a paging message including a resource offset for indicating an offset for uplink allocation. The M2M equipment transmits a ranging request message using the uplink allocation.

Claims

1. A method of operation in an idle mode for Machine To Machine (M2M) communication, comprising:

receiving, by a M2M device in the idle mode, a paging message from a base station, the paging message including an action code, an access type and a resource offset, the action code indicating that the M2M device perform a ranging for a network reentry, the access type indicating a type for the network reentry, the resource offset indicating an offset for an uplink assignment if the access type indicates a dedicated ranging channel allocation,

wherein the paging message further includes a group identifier that identifies a group to which the M2M device belongs;

receiving, by the M2M device, the uplink assignment based on the resource offset,

wherein the resource offset indicates the offset that the M2M device starts to monitor the uplink assignment; and

transmitting, by the M2M device, a ranging request message to the base station by using the uplink assignment.

2. The method of claim 1, wherein the M2M device terminates the idle mode upon receiving the paging message.

3. The method of claim 1, wherein the uplink assignment is a code division multiple access (CDMA) allocation advanced-MAP (A-MAP).

4. A device for Machine To Machine (M2M) communication, comprising:

a radio frequency unit configured to receive and transmit a radio signal; and

a processor operatively coupled with the radio frequency unit and configured to;

receive a paging message from a base station while operated in an idle mode, the paging message including an action code, an access type and a resource offset, the action code indicating that the device perform a ranging for a network reentry, the access type indicating a type for the network reentry, the resource offset indicating an offset for an uplink assignment if the access type indicates a dedicated ranging channel allocation,

wherein the paging message further includes a group identifier that identifies a group to which the M2M device belongs;

receive the uplink assignment based on the resource offset,

wherein the resource offset indicates the offset that the M2M device starts to monitor the uplink assignment; and

transmit a ranging request message to the base station by using the uplink assignment.

5. The device of claim 4, wherein the processor is configured to terminate the idle mode upon receiving the paging message.

6. The device of claim 4, wherein the uplink assignment is a code division multiple access (CDMA) allocation advanced-MAP (A-MAP).
