The user control type transmission power control in hand over of the CDMA system

摘要

SolutionsMethod and the device in order to control the transmission electric power of the Mobile user device which is base station of the radio communication system and in the midst of radio communication are offered. Transmission electric power of the user device is controlled by the communication system. Immediately before the transmission of the event message by the user device, message in order to increase the possibility of being received appropriately depending upon base station, transmission electric power it increases by the user device. Transmission electric power increases by opening the closed loop power control circuit which usually controls the transmission electric power of the user device. The user device takes over the control for increasing the transmission electric power by opening the closed loop circuit. Following to the transmission of message, the user device in order to transmit by the electric power which increases by increasing the set point of signal anti- interference ratio in order to control the power level of base station, may control base station. Because of this, the possibility of receiving verification message and event message from base station increases. Selective figure Figure 3
