For providing power control for a mobile station in a mobile communication, in connection with accomplishing a handover of the mobile station from a presently serving cell to a target cell, each cell is assigned a maximum transmitting power level at which mobile stations are allowed to transmit in the cell. The receive level of the downlink signal of the handover target cell is measured at the mobile station prior to the handover, and the transmitting power level of the measured receive level of the downlink signal of the target cell. The mobile station is commanded to use the determined transmitting power level as its initial output power level in the target cell following the handover. The transmitting power level of the mobile station following the handover is lower than the maximum transmitting power level of the target cell by an amount equal to the difference between the optimum level of the uplink signal of the target cell and the measured receive level of the downlink signal of the target cell as measured prior to the handover, if the measured receive level of the target cell is higher than the optimum level of the uplink signal of the target cell.

[ I claim:] [1.] A power control method for handover to a handover target cell in a mobile communication system including mobile stations and cells, comprising the steps of:assigning each cell a maximum transmitting level at which mobile stations are allowed to transmit in the respective cell,measuring the receive level of the handover target cell at a respective mobile station prior to the handover,determining the transmitting power level of the mobile station for said target cell by utilizing the measured receive level of a downlink signal of the target cell, andcommanding the mobile station to use said determined transmitting power level as an initial output power level in the target cell following the handover.
