After the scores of the three dimensions are obtained, a score proportion is given to each dimension, and the comprehensive score calculation is carried out, so that a comprehensive score can be obtained. Examples of the invention
In the embodiment of the invention, under the condition that the coverage effect of the 4G cell is not good, the 2G cell is scored by collecting the data generated by the 4G user in the 2G cell, so that the coverage effect of the 4G cell is reversely evaluated, wherein the higher the score of the 2G cell is, the more the user data generated by the 4G user flowing back to the 2G cell is, the worse the coverage effect of the 4G cell is.
