Based on the sampling MDT data of LTE network

as well as 4 G/5 G co-site information and basic data from co-build and co-share agreement

according to the completion time of the 5 G site installation

using python to calculate the differences in coverage azimuth and coverage distance of the 4 G macro cell before and after the installation

check the abnormal cells with large differences in coverage to con? rm whether 4 G cell antenna’s azimuth

downtilt angle

position

height

environment

etc.

have changed due to the installation and construction of 5 G site

which then affect the 4 G network coverage consequently. Optimizing and adjusting 4 G cells with abnormal network changes timely is contributed to maintain stable network quality and avoid poor user perception and user complaints. This method can effectively identify network changes instantly and eliminate the hidden trouble. It is valuable for popularized application and prospect.
