Fast and accurate positioning the data service problem of 4G

which can improve the QoS of 4G. The paper joint consider the end-to-end and the whole service process when user using 4G network

then propose a method named ba-yuan-ba-jie to improve the QoS of 4G. The method can analyze the service of 4G through step by step

and slove the problem one by one

which is one of the best method to handle the service of 4G. At the last

the method can be dis-played as system development to achieve automated analysis.
