With the development of LTE service and the scale of users

the number of base stations is increasing

the speed of base station opening is quickening

the network environment is becoming more complex

the diffi culty and the task of the network are increasing. The traditional road test is diffi cult to realize realtime and full scene coverage

and the accuracy needs to be improved urgently. Based on the limitation of traditional way of road measurement

MDT uses the network running terminal to carry on the realtime road survey and report

not only saves the manpower and material resources of the traditional road test

but also can achieve full coverage and real-time monitoring. In this paper

the technical background and algorithm design of the minimized road measurement technology are analyzed and explained. By comparing the similarities and differences of the shortest path measuring technique

the traditional road test and the common MR data

the MDT precision is highlighted. Then

through comparison verifi cation

MDT road test comparison and region based MDT data comparison verifi cation are given. Finally

the hotspots of complaints are selected

and the MDT implementation scheme is tested to optimize the network structure.
