PURPOSE: A method and a system for distributing traffic loads in a mobile station are provided to compare a power strength reference value of a pilot channel received from a serving base station in a corresponding cell with a power strength of a pilot channel received from a new base station, so as to quickly decide whether to perform soft handover to the new base station. CONSTITUTION: A handover region deciding unit receives and analyzes a message that requests traffic loads distribution(S201), to check whether a power strength reference value of a pilot channel received from a serving base station is smaller than a power strength of a pilot channel received from a new base station(S202). If so, soft handover to the new base station is decided(S203), and if not smaller, general handover is performed(S204). A handover performing unit decides whether to register the new base station in an active set of a corresponding mobile station(S205). A state checking unit checks whether the active set of the mobile station is in a saturation state(S206). If not, the new base station is registered in the active set of the mobile station(S207). If the active set is in a saturation state, a base station eliminating unit eliminates the serving base station in accordance with a predetermined formula(S208). And a base station replacing unit replaces a base station having the worst pilot strength among base stations registered in the active set of the mobile station by a base station having the best pilot strength among base stations registered in a monitoring set in accordance with a predetermined formula, thereby performing speed soft handover to the new base station(S209).
