1. A method for performing a ranging for Machine To Machine (M2M) communication, comprising:
- periodically receiving, by a M2M device, a system configuration descriptor message including first dedicated ranging channel allocation information;
entering, by the M2M device, into an idle mode;
receiving, by the M2M device in the idle mode, a paging message from a base station, the paging message including second dedicated ranging channel allocation information and a dedicated channel allocation timer; and
transmitting, by the M2M device, a ranging code to the base station in accordance with the second dedicated ranging channel allocation information when the second dedicated ranging channel allocation information is valid,wherein the second dedicated ranging channel allocation information included in the paging message is valid within a time duration indicated by the dedicated channel allocation timer when the second dedicated ranging channel allocation information in the paging message is different from the first dedicated ranging channel allocation information allocated via the system configuration descriptor message, andwherein the first and second dedicated ranging channel allocation information are used for performing a ranging procedure.

4. A Machine To Machine (M2M) device configured for performing a ranging for M2M communication, comprising:
-
a radio frequency unit for receiving and transmitting a radio signal; and a processor operatively coupled with the radio frequency unit and configured to; periodically receive a first system configuration descriptor message including dedicated ranging channel allocation information; enter into an idle mode; receive a paging message from a base station, the paging message including second dedicated ranging channel allocation information and a dedicated channel allocation timer; and instruct the radio frequency unit to transmit a ranging code to the base station in accordance with the second dedicated ranging channel allocation information when the second dedicated ranging channel allocation information is valid, wherein the second dedicated ranging channel allocation information included in the paging message is valid within a time duration indicated by the dedicated channel allocation timer when the second dedicated ranging channel allocation information allocated through the paging message is different from the first dedicated ranging channel allocation information allocated via the system configuration descriptor message, and wherein the first and second dedicated ranging channel allocation information are used for performing a ranging procedure. - View Dependent Claims (5, 6)
