METHOD AND DEVICE FOR CONTROLLING FORWARD TRAFFIC CHANNEL POWER OF CDMA RADIO SUBSCRIBER NETWORK SYSTEM

摘要

PROBLEM TO BE SOLVED: To reduce the interference signal power of a forward link which is due to traffic increase and to obtain an appropriate traffic (speech communication) quality to a terminal station by deciding whether full power that has been allocated to a forward traffic channel of the terminal station is a normal mode or a critical mode, comparing a receiving bit energy/noise ratio with a power control critical value and increasing or reducing sending power according the difference. SOLUTION: When signal information is received from a mother base station 200, it is transmitted to a terminal station traffic channel demodulator 212 and is modulated. A forward traffic channel receiving bit energy/noise ratio measuring part 214 measures a receiving bit energy/noise ratio of a traffic channel from demodulated receiving data. The power increase or reduction with respect to the forward traffic channel is decided by comparing the receiving bit energy/noise ratio with the power control critical value of the forward traffic channel. Thus, a traffic quality of a good quality can be acquired to a terminal station.
