Abstract:
1. A device for power overload control of a trunking group forward supplemental channel for setting the higher limit of a forward supplemental channel transmitting power of sector trunking group and controlling power overloads, characterized in that comprises: a sector power saving and overload judgment module for saving a sector power and judging whether the sector power is overload; a sector power overload control module for reducing or increasing the higher limit of the forward supplemental channel transmitting power of the sector trunking groups users correspondingly based on whether the sector power is overload, and setting the changed higher limit of the forward supplemental channel transmitting power of the sector trunking group as the target maximum transmitting power of the trunking group forward supplemental channels; a trunking group forward supplemental channel power control module for dividing the sector trunking group users into groups based on a channel board, and determining the adjusting step size based on the ratio between a trunking group combining transmitting power of the users divided and a forward supplemental channel shared transmitting power of the sector trunking group, the comparison between the forward supplemental channel shared transmitting power of the sector trunking group and a target maximum transmitting power of the trunking group forward supplemental channels, and adjusting the higher limit of the forward supplemental channel transmitting power of the trunking group based on the adjusting step size.
