Claim Text:
1. A method for optimizing a tradeoff between capacity and coverage of a network, the method comprising: receiving statistical information and a first count that are sent by a base station, wherein the first count is the number of all user equipments (UEs) counted by the base station, the statistical information comprises information related to a coverage hole (CH) of the base station and/or information related to a coverage overlap (CO) of the base station; establishing at least one coverage cluster according to the received statistical information, and calculating cluster values of all the coverage clusters according to the first count and the statistical information, wherein the coverage cluster is used for recording a base station identifier related to the CH or a base station identifier related to the CO, and the cluster value is a CH value or a CO value of each coverage cluster; acquiring an entire-network CH value and an entire-network CO value according to the cluster values of all the coverage clusters; calculating an entire-network utility value according to the entire-network CH value and the entire-network CO value; determining, according to the entire-network utility value, whether a capacity or coverage weight and an antenna downtilt of each base station in all the coverage clusters need to be adjusted; if the adjustment is needed, acquiring an adjustment value for the capacity or coverage weight of each base station and an adjustment value for the antenna downtilt of each base station according to an optimization strategy; sending the acquired adjustment value for the capacity or coverage weight of each base station and the acquired adjustment value for the antenna downtilt of each base station to a corresponding base station, so that the base station calculates the optimal pilot power.
