    Abstract: PURPOSE: An apparatus and method for controlling a transmission power of a mobile communication terminal is provided to remove phenomenon in which the transmission power is instantaneously increased or decreased according to a switching of a power amplifier. CONSTITUTION: The first power amplifier(330) outputs an RF(Radio Frequency) signal which is more a predetermined power level. The second power amplifier(380) is connected to the first power amplifier(330) in parallel, and outputs an RF signal which is less than the power level. A variable attenuator(320) is located at a front terminal of the first power amplifier(330). An RSSI(Received Signal Strength Indicator) detecting unit(360) detects the strength of a received signal. A control unit(370) determines an output power level according to the detected strength of the received signal, controls the variable attenuator(320) for adjusting a difference of power gains of two power amplifiers(330,380) as a value within a predetermined range, and selects one between the first and second amplifiers(330,380). A power supply unit(350) supplies an operation power suitable for the selected power amplifier so that the input RF signal is amplified by the selected power amplifier and the amplified RF signal is transmitted.

    Abstract: PURPOSE: An apparatus and a method for determining a paging warning mode in a mobile communication system are provided to set up a paging warning mode in a mobile communication system. CONSTITUTION: A mobile terminal judges whether a broadcasting channel message is received(610). If the broadcasting channel message is received, the mobile terminal analyzes subcell information and a beacon paging cycle contained in the broadcasting channel message(612). After temporarily storing subcell information and the beacon paging cycle, the mobile terminal judges whether the current cell contains a subcell(614). If it is judged that the subcell exists, the mobile terminal determines a paging group, which it belongs to, using its own ID and the number of paging groups(618). After determining the paging group, the mobile terminal accesses a beacon paging group frame and the determined paging group frame at the same time(620). The mobile terminal receives the beacon paging group frame through the access of the beacon paging group frame. Grasping beacon paging group information, the mobile terminal judges whether a change of a paging warning mode is required(622). If it is judged that the paging warning mode change request has been received, the mobile terminal transfers the current mode into a vibration mode(624).
