Method and apparatus for performing soft hand-off in a wireless communication system

A providing soft handover in a mobile communication system and method and device, according to the far-end) and communication multiple base stations signal energies calculates, a threshold value; A along the base station signal energy observed value and threshold value; and comparesAnd when the additional base depot's signal energy observed value super-junction the threshold value; and base station. Additionally, wherein the instruction a far-end base station signal strength the signal strength measurement information from multiple base stations; Selecting two base stations as member for base station according team; Signal strength adding together with the member of working team, reportThe signal strength for working team member add together, calculates a threshold value; And an threshold value to compare the signal strength of wherein of base station for reporting of determining to the additional member in the team. The invention with the de-repeated data to send a soft handover to the base station number of mobile station and is smaller, and providing transmission of flexibly.
