1. A method of accessing a base station by a first machine to machine (M2M) mobile station in a wireless communication, the method comprising:
- broadcasting, to a base station via a first channel, an advertising message;
wherein the first channel is randomly selected by the first M2M mobile station among a plurality of channels available to the first M2M mobile station,wherein the advertisement message is relayed to the base station via a second M2M mobile station when the first channel is selected, andwherein the advertising message contains an address of the first M2M mobile station, a type of the first M2M mobile station, a service category, a sleep interval and a listening duration; and
receiving, from the base station via the second M2M mobile station, an invite message permitting the first M2M mobile station to access the base station after the base station judges that the first M2M mobile station is permitted to access the base station based on the advertising message,wherein, when the first M2M mobile station receives the invite message from the base station in the listening duration, an access procedure with the base station is performed according to the invite message,wherein, when the first M2M mobile station does not receive the invite message from the base station in the listening duration, a sleep mode is performed during the sleep interval,wherein the advertising message is re-broadcasted via a second channel via the second M2M mobile station after the sleep interval is passed by, andwherein the second channel is randomly selected by the first M2M mobile station among a plurality of channels available to the first M2M mobile station.
