The invention relates to the technical field of wireless mobile communication, specifically to a dual band network automatic telephone traffic and quality balancing method based on measurement report, which is characterized in that the method optimizes network parameters by a configuring data processing sub-system, an interference mode building sub-system, a basic data management sub-system, a network analyzing sub-system, an antenna feeder parameter optimizing sub-system, a re-chosen and switched parameter optimizing sub-system, a neighboring area optimizing sub-system and a network property assessing sub-system. The method can reflect network condition truly along with high working efficiency, reduce cost of repeatedly ''optimizing-assessing-optimizing'', shorten optimizing time, reduce workload, evenly consider all cells in the optimized zone, automatically balance all parameters and guarantee the optimized result. The method provides a total solution, so the total performance of the local area wireless network is the best in optimizing RF parameters, optimizing the re-chosen and switched parameters as well as in optimizing neighboring areas.
