Power control method and arrangement for handover in a mobile communication system

The invention relates to a mobile communication system power control method and protocol of handover. Is average speeds to each cell is in the highest the power level of the transmitting cell, and mobile station for uplink signal optimizing layer is tracking handover flowing achieve. Target cell received layer is a obtaining is higher than the target cell uplink signal optimizing layer, a tracking handover in the power layer of mobile is lower than the target cell highest the power layer, wherein the lowers value is equal to the front the target cell uplink signal optimizing layer receiving layer and handover difference of the target cell downlink signal receiving layer, obtaining.
