ABSTRACT:
A method and device for controlling a mobile user equipment being in radio communication with base stations of a wireless communication system. The transmit power of the user equipment is controlled by the communication system. Immediately before sending an event message by the user equipment, the transmit power is increased by the user equipment, in order to increase the likelihood that the message is properly received by the base station. The message may be a soft handover event message. The transmit power is increased by opening a closed loop power control circuit, which normally controls the transmit power of the user equipment. By opening the closed loop circuit, the user equipment takes over the control of its transmitted power for increase thereof. Following the sending of the message, the user equipment may control the base station to send with increased power by increasing a target signal-to-interference ratio value (SIRref) by means of which the base station power level is controlled. In this way, the likelihood of receiving any acknowledgement messages and event messages from the base station is increased.
