Abstract: PURPOSE: A synchronization method for broadcast multicast service and an apparatus thereof are provided to dynamically solve inconsistency of broadcast service start time among base stations which can occur in starting the broadcasting service. CONSTITUTION: If it is later than service start setting time among checking times of checking the change about the broadcasting service with a constant period, a calculation unit (420) compares a change checking time closest to the service start setting time with the service start setting time. If it is judged that the change checking time is later than the service start setting time over pre-set inside float time, the calculation unit determines the change checking time as a service start time when the broadcasting service starts. A communication unit (430) transmits the information about the service starting time to at least one base station. [Reference numerals] (410) Receiving unit; (420) Calculation unit; (430) Communication unit; (AA) Session start request message; (BB) Session start setting time; (CC,DD) Service start time

Abstract: PURPOSE: A base station and a method for operating the base station are provided to dynamically vary low-duty cycles according to the amount of traffics. CONSTITUTION: The amount of traffics is measured in a downlink buffer. The measured amount of the traffics is compared to a threshold value. Based on the comparison result, a first rate between an active section and an inactive section is adjusted. If the measured amount of the traffics is higher than the threshold value, a second rate of the amount of the traffics with respect to the threshold value is determined. According to the second rate, the first rate is adjusted.
