Abstract:
1. A method for optimizing network coverage and capacity, comprising: judging by a NodeB whether there is a coverage and capacity problem based on set threshold parameters for collected coverage and capacity optimizing data, and if yes, determining by the NodeB a solution strategy according to the existing coverage and capacity problem and the coverage and capacity optimizing data causing the problem; wherein, the step of judging by a NodeB whether there is a coverage and capacity problem based on the set threshold parameters for the collected coverage and capacity optimizing data is at least one of the following: setting a threshold for cell signal quality and a threshold for a number of cell switching failures in the NodeB, once the signal quality in the coverage and capacity optimizing data of the cell collected by the NodeB is lower than the set threshold and the number of the cell switching failures surpasses the set threshold, it is believed that the cell has a coverage loss problem; and setting a threshold for the number of dropped calls in the NodeB, when the number of the dropped calls in the coverage and capacity optimizing data of the cell collected by the NodeB surpasses the threshold, it is determined that a cell adjacent to this cell has been deleted according to cell deletion information of a adjacent NodeB, and it is believed that the cell has the coverage loss problem.
