Title:
METHOD AND APPARATUS FOR TRANSMITTING BROADCASTING MESSAGE IN WIRELESS ACCESS SYSTEM SUPPORTING M2M ENVIRONMENT
Document Type and Number:
WIPO Patent Application WO/2012/177084
Kind Code:
A3
Abstract:
The present invention relates to a wireless access system supporting an M2M environment, and provides a method and an apparatus for broadcasting a medium access control (MAC) control message. A method for receiving a broadcasting message from the wireless access system supporting the M2M environment, according to one embodiment of the present invention, comprises the steps of: an M2M equipment receiving a broadcast allocation map information element including a message type field, which shows the type of the broadcasting message, and resource allocation information, which shows an allocation region of a broadcasting burst from which the broadcasting message is transmitted; and the M2M equipment confirming the type of the broadcasting message which is shown by the message type field, wherein when the broadcasting message type is related to the M2M equipment, the M2M equipment receives the broadcasting message through the broadcasting burst that is indicated by the resource allocation information, and when the broadcasting message type is not related to the M2M equipment, the M2M equipment does not decode the broadcasting burst that is indicated by the resource allocation information.
