Study Of Bozhou Telecom LTE Wireless Network Optimization

The LTE(LongTerm Evolution)scheme was proposed by 3GPP,which is compatible with current 3G telecommunications system.Channel estimation plays a quite important role in the LTE system which requires high data rate,high quality and high mobility. Long Term Evolution aimed at achieving 100 Mbps peak rate in 20 MHz bandwidth and 50 Mbps in uplink ale carried out in 3GPP.At present the international mainstream has two kinds of TDD- LTE and FDD- LTE standard, the FDD and TDD LTE standard two mode is essentially the same, there are only small differences between two patterns, similarity of 90%. With the rapid development of the information age, people are more and more inseparable from the mobile phone, so the wireless network is becoming more and more important. Gradually increase of mobile phone users, also make the network pressure is increasing. So on LTE wireless network optimization work, is particularly important.Network optimization is a process to improve the quality of the whole network, to ensure the effective use of network resources. Traditional network in a large number of users will cause the network congestion, the user’s perception of poor, the end user of the network is reduced, resulting in a reduction in the operation of commercial brand image. Therefore, this thesis takes Bozhou Telecom FDD-LTE network as an example to discuss the theory and process of cluster optimization, so as to guarantee and improve the quality of the network, improve the competitiveness of enterprises and customer satisfaction. First of all, according to the Bozhou urban area and the county area of the terrain, the regional environmental characteristics, the same TAC region and other information to cluster. Secondly, the use of Probe tools to collect DT data, and to quantify the data to get the need for optimization of the indicators, and the problem points to be classified to determine the priority of the adjustment. Finally, based on the analysis of the previous data, the index is compared and analyzed, and the reasons for the adjustment of the non-effective points are analyzed, and the corresponding engineering optimization scheme is put forward.
