Vo LTE voice quality optimization is the important content optimization

but relatively lack. Because the problem analysis and optimization methods positioning precision is low and cannot meet the required by the current optimization. We explored a new method to position the problem of voice quality by fi tting " basestation MOS scores " and Vo LTE " Call history Information ". This method which based on MOS scores

realized the problem of voice quality quasi-call level. This method is based on the call logs which combined with the MR

traffi c statistics

and base station engineering parameters

the performance of the base station parameters

alarms

and operation records data

for problem location and data analysis. It has a greate improvement compared with the traditional way of optimization in positioning comprehensive

real-time and precision.
