摘要
A node connected to a radio network controller has a target Signal to Interference Ratio (SIR) used in the mobile system in carrying out uplink inner loop power control. Updating of the target SIR is carried out as uplink outer loop power control by the radio network controller provided with a wait-timer which produces a time-out signal when said wait-timer times a preselected time duration after the wait-timer is set. The radio network controller judges whether or not the radio network controller receives from the node a report representative of a radio condition around the node before the wait-timer produces the time-out signal. The radio network controller updates the target SIR into a new target SIR on the basis of the report when the radio network controller judges that the radio network controller receives from the node the report before the wait-timer produces the time-out signal. The radio network controller again sets the wait-timer when the target SIR is updated into the new target SIR. The radio network controller decreases the target SIR by a predetermined value into a decreased target SIR when the radio network controller judges that the radio network controller does not yet receive from the node the report when the wait-timer produces the time-out signal. The radio network controller again sets the wait-timer when the target SIR is decreased into the decreased target SIR.
