Method for controlling host computer operation in indoor distribution system and device thereof

The invention discloses a method for controlling host computer operation in an indoor distribution system. The method comprises the following steps: comparing outdoor signal strength received by a receiving antenna in the indoor distribution system with a threshold value; controlling opening of the host computer when the outdoor signal strength is lower than the threshold value; and controlling close of the host computer when the outdoor signal strength is not lower than the threshold value. The invention simultaneously discloses a host computer operation controlling device in the indoor distribution system. By adopting the method and the device, interference of the indoor host computer on an outdoor base station can be avoided under the condition that the indoor signal coverage requirement is fulfilled.
