With increasing of LTE network load

the network structure problem and the same frequency interference is becoming more and more obvious

which has bad infl uence on user perception. Therefore

network structure optimization is very important. The traditional method of network structure optimization is very ineffi cient. To solve a problem cell

we need to adjust several neighboring cells. If too many cells are adjusted

it will affect the operation of network

and also lead to more new network structure problems. This paper has provided the network structure optimization method using interference source location

which can quickly and accurately locate the network structure problem area and the main interference source in the region. By adjusting the main interference source

the index of all disturbed cells in the region is improved signifi cantly

and the quality and effi ciency of the optimization are greatly improved.
