With the promotion and usage of LTE

the depth coverage has becoming one of the key indicators of user perceptions. However

due to the complexity of networks and the resource constraints

it’s difficult to identify the pain points and causes efficiently and accurately. To solve this problem

we propose an automatic analysis tool based on R language and the big data

which could obtain the list of weak coverage cells and the corresponding preliminary solutions including the malfunction type verification

parameter verification and peripheral zero traffic cells verification. With GIS presentation

the proposed tool would provide accurate direction for the following on-site inspection.
