ABSTRACT:
Disclosed is a mobile communication terminal that includes: a radio unit for receiving a broadcast control channel signal including cell information and transmitting a random access channel signal for a call allocation request to a corresponding cell; a reception power level measurement unit for measuring reception power levels of the broadcast control channel signal; a transmission power level calculation unit for calculating a transmission power level of the random access channel signal based on the measured reception power levels and the cell information; a key input unit for outputting a signal corresponding to network connection request by a user; and a controller for acquiring system information after synchronizing with a strongest broadcast control channel signal according to the measured reception power level, and controlling the random access channel signal for the call allocation request to be transmitted at the calculated transmission power level when the signal corresponding to the network connection request is input.
