| 发明名称 | Method and device for ranging in a wireless communication system | ||
| 摘要 | Provided are a method and device for ranging in a wireless communication system. A machine-to-machine (M2M) device receives an advanced air interface-system configuration descriptor (AAI-SCD) message including information on a dedicated ranging channel for the M2M device and an M2M parameter change count from a base station, and attempts ranging through the dedicated ranging channel to the base station. At this point, the M2M parameter change count orders information on the dedicated ranging channel in the AAI-SCD message to change. | ||

| 主权项 | 1. A method for ranging, by a machine-to-machine (M2M) device, in a wireless communication system, the method comprising: receiving an opportunity index included in a random access identifier (RA-ID), wherein the opportunity index is masked with a CDMA allocation A-MAP information element (IE); receiving an Advanced Air Interface-System Configuration Descriptor (AAI-SCD) message including information on a dedicated ranging channel for the M2M device and a M2M parameter change count from a base station; and transmitting a ranging request message to the base station through the dedicated ranging channel, wherein the M2M parameter change count indicates that the information on the dedicated ranging channel in the AAI-SCD message has changed, and wherein the information on the dedicated ranging channel for the M2M device relates to a M2M ranging indicator indicating dedicated ranging for the M2M device. | ||
