| 发明名称 | Method and apparatus for allocating device identifiers (STID) in a wireless access system | ||
| 摘要 | The present description provides a method for allocating a device identifier through an initial network entry process with a base station in a wireless access system. The method comprises a step of transmitting control information, indicating a mobile station supporting Machine to Machine (M2M) communication, to a base station; and receiving a first message, comprising at least one of a first identifier indicative of a group to which devices belong and a second identifier indicative of each of the devices belonging to the group, from the base station. | ||

| 主权项 | 1. A method for machine-to-machine (M2M) communication in a wireless access system, the method comprising: receiving, by a M2M device from a base station, a M2M group identifier (MGID) being identification information related to a M2M group to which the M2M device belongs; applying, by the M2M device, the MGID to a cyclic redundancy check (CRC) mask; and decoding, by the M2M device, a message, which is in form of an advanced map information element (A-MAP IE) based on the CRC mask, wherein the CRC mask includes a masking prefix, a type indicator and a masking code. | ||
