Abstract:
A transmission power control system for a mobile communication network comprising a radio base station (50.sub.1) having a service area, a host station (11) connected to said radio base station and constituting a fixed station together with said radio base station, and a mobile terminal (13) present within said service area, said transmission power control system comprising, in said radio base station, transmission power control means (37, 48, 52) for carrying out transmission power control of said mobile terminal by transmitting, in dependence upon a signal power of a received signal received from said mobile terminal, said mobile terminal with a control signal requesting a decrease of transmission power of said mobile terminal, said transmission power control system further comprising in said fixed station:abnormal terminal detecting means (48, 49, 52) connected to said transmission power control means for detecting said mobile terminal as an abnormal terminal when said mobile terminal does not decrease the transmission power after said transmission power control means transmits said mobile terminal with said control signal, said abnormal terminal detecting means transmitting, when detects said abnormal terminal, said abnormal terminal with a forced communication-disabling signal which is for use in said abnormal terminal in forcedly disabling communication when said abnormal terminal receives said forced communication-disabling signal.
