There are many weak coverage problems in 5 G network

so it is necessary to continue to evaluate and locate the weak coverage location

so as to carry out targeted optimization and optimization work. However

5 G now has few user sampling points

5 G network management does not support data reporting of MDT and MR temporarily

but there are various disadvantages in coverage evaluation by means of on-site test and simulation. Therefore

this paper mainly proposes a method to evaluate 5 G coverage of MDT data based on 4 G. This method has short analysis period

high accuracy and wide applicability

which can not only evaluate 5 G coverage of the whole network area

but also precisely locate 5 G weak coverage the area.
