Research on Maintenance and Fault Treatment of TD-LTE Equipment

With the construction of large scale TD-LTE eNodeB, the number and type of eNodeB fault will increase,the failure of eNodeB will directly affect the construction and network quality of TD-LTE system. This paper takes the Datang Mobile EMB5116 TD-LTE eNodeB as the platform, through the project practice, classifies and analyzes the typical faults of the TD-LTE eNodeB in the process of installation, opening, maintenance and optimization. According to the fault type, the fault location method is determined. The article sums up the process of fault handling on the base station, and then analyzes the positioning GPS fault, RF fault, transmission fault and processing method in the form of case,forms the eNodeB problem locating and troubleshooting case library of TD-LTE, Thus, it can effectively shorten the fault duration of eNodeB, improve the efficiency of fault repair, achieve the purpose of communication network security more effectively.
