In addition, the reliability of control packets sent over the dedicated link flow can be improved upon by increasing the number of retransmissions associated with the control packets and / or decreasing the window of time before the retransmissions are sent. A system, mobile terminal, network entity, and computer program product for implementing the method are also provided.

Presence / absence of a failure in a feedback control system of a motor is monitored. When a failure is detected in the feedback control system, the motor is driven by switching to an open-loop control. During the open-loop control, the motor is rotated by sequentially switching the motor current supply phase without feeding back encoder count information. The position count is incremented or decremented every time the current supply phase is switched. When the position count has reached a target count, it is determined that the rotor has reached a target position, whereupon the open-loop control is finished.
