Abstract: PURPOSE: A method for controlling power of a base station is provided to control a pico-cell base station not to regulate or raise transmission power of a mobile terminal, when the mobile terminal moves between a pico-cell and a macro-cell, so as to perform soft hand-off. And the method is provided to set up a backward boundary of the pico-cell larger than a forward boundary, to reduce power of the mobile terminal. CONSTITUTION: If a mobile terminal located in a macro-cell moves to a pico-cell and enters a hand-off range, the mobile terminal transmits a PSMM(Pilot Strength Measure Message) to a base station(A) serving the macro-cell(S600). A base station controller analyzes the PSMM, and requests channel allocation for hand-off to a base station(B) serving the pico-cell, if the hand-off is decided to be necessary. During the hand-off, the base station(B) transmits a power control command to the mobile terminal, make the pico-cell not regulate transmission power of the mobile terminal or raise transmission power. Accordingly, the base station(B) does not lower signal power of the mobile terminal. The mobile terminal transmits transmission power identical with transmission power of connection with the base station(A) in the hand-off range, and the base station(B) allocates a channel requested from the base station controller. If information on the channel allocation is received from the base station(B), the base station controller requests hand-off to the base stations(A,B) and transmits an extended hand-off direction message to the mobile terminal through the base stations(A,B)(S601). The mobile terminal adds the base station(B) to an activated aggregate, and sets up a speech channel with the base station(B), then transmits a hand-off complete message to the base stations(A,B) to turn the base stations(A,B) to a hand-off state(S602).
