Adjust back scene and carry out radio network optimization.
Further, in the present embodiment, for benchmark scene, when carrying out radio network optimization according to benchmark combination solution, prison
Survey the running status and default network performance index of benchmark scene.Wherein, it is pre- for each default network performance index
One number range is first set, if running status deteriorates or default network performance index is not in the range of default value, said
Bright use benchmark combination solution is not applicable for the benchmark scene, then the benchmark scene is adjusted back, the benchmark scene is changed
For readjustment scene, the readjustment scene is redefined in the optimal solution of RS power ratio parameter groups, the present embodiment, it is determined that readjustment field
The optimal solution of the RS power ratio parameter groups of scape is conservative combination solution, and carries out wireless network to readjustment scene according to conservative combination solution
Network optimizes, to ensure that the readjustment scene is effectively improved in a large amount of network performance indexes.
Wherein, default network performance index can for it is following any one or more：
Percent of call completed that 4G is wireless, LTE business drop rate, blow back into switching out success rate, downstream rate, single current ratio, 4G frequently
3G several ratio, TA abnormal distribution sampled points ratio, 4G flow accountings.
