With the accelerate developing of 4G network

the paper mainly studies data traffic resides in LTE network strategy and 3G/4G common mode optimizing strategy in order to improve the ability of 4G mobile highly possible staying on 4G network. By collecting the process and method of LTE distribution

4G distribution intelligent optimization platform has been developed. Furthermore

the paper also deeply analyses dimensional LTE distribution

and summarizes three-step optimization method of backflow grids which effectively guiding LTE programming

constructing and optimizing. Through solidifying the optimization of the algorithm

strategy and outcome can be presented automatically that highly improve the accuracy of the problem and greatly improve the work efficency. Since the project putting into effect

the data traffic flow in 4G network increases apparently and the split ratio of data traffic and the length of time both receive a significant boost.
