ない。Next, the operation will be described. The sensor 8 detects the environmental temperature of the wireless base station 1 and outputs a signal indicating the range of the detected temperature to the control device 10 via a signal line 19 in real time. Here, the temperature range is divided into three: "normal", "high temperature", and "abnormal high temperature". When the environmental temperature of the wireless base station 1 is “high temperature”, the wireless base station 1 can operate for a short time, and when the environmental temperature is “abnormally high”, normal operation of the wireless base station 1 is not guaranteed.

The following control is performed to stop the power supply to the power supply 6. That is, the control device 10 first controls the communication line switch 9 to transfer the traffic of the communication line 11 and the traffic of the communication line 13 to the communication lines 12 and 1 respectively.

Is turned off, the contacts a and c are opened (the state shown in the figure), and the power supply to the amplifiers 4 and 6 is stopped. Therefore, the amplifiers 4 and 6 stop operating, and the heat from the amplifiers 4 and 6 disappears, so that the environmental temperature of the wireless base station 1 falls to a temperature in a normal range. In the meantime, 50% of the amplifiers, i.e. amplifiers 5 and 7, are powered, so that traffic is carried through them.

Is at a predetermined level, the base station controller hands over traffic of a line corresponding to a predetermined number of amplifiers to a line corresponding to another amplifier. When the temperature detected by the temperature detecting means is at a predetermined level, the power control means cuts off the power of a predetermined number of amplifiers. As a result, even if the environmental temperature of the wireless base station rises abnormally, the power supply of the amplifier, which is a main heat source, is shut off to stop the operation, and the environmental temperature can be lowered to the normal range. In the meantime, traffic can be carried through the remaining powered amplifiers.
