The present invention relates to the field of communications, and in particular, to a method and a device for turning off a carrier frequency slot.

Background Art In a communication base station of a GSM (Global System for Mobile Communicating System), a radio frequency module is responsible for transmitting and receiving information. Each radio frequency module should be composed of at least one BCCH (Broadcast Control Channel) transceiver. The BCCH transceiver provides a total of eight time slots from TS0 to TS7. The TS0 provides the relevant control information of the base station, which is called channel control. Time slots, TS1 to TS7 can be used to send and receive voice and data services of users, called service time slots. The GPRS (Traffic Channel) transceiver can also be added to the RF module based on the presence of the BCCH transceiver. The TCH transceiver is used to specifically send and receive voice and data services.

At present, GSM operators pay attention not only to the power consumption of base station equipment during peak hours, but also to the power consumption of base station equipment during low-load periods. It is found that the RF module of the GSM base station is in a low load or no load state every day for 60% to 70% of the time, which is not only inefficient, but also consumes a lot of power. The prior art provides a solution for a multi-carrier power amplifier, that is, a radio frequency module composed of one BCCH transceiver and a plurality of TCH transceivers, in the case where the service is relatively small, by idle time of the TCH transceiver The gap is turned off to achieve energy savings, and the BCCH transceiver needs to turn on all eight time slots for full power transmission.

However, the power consumption of the prior art base station is still relatively high and cannot be reduced as much as possible.
