Prediction of interference areas for 3G network based on drive test and throughput data
Seksan Charoenlap, Peerapong Uthansakul · 2016
The growth of customers in 3G network has forced the operators to always optimize their network performances. One of the most concerned parameters to indicate the quality of network is the interference area. Especially in 3G network, this parameter is directly influenced by the number of users. Hence, it would be better if the operators can predict the areas experiencing interference before getting the users complaint. However, it is rarely possible to mathematically realize the interference power for all areas without real measurements. This is because in practice the fading channels depend on individual characteristic of environments. In this paper, based on drive test and throughput data, the method to predict the interference areas have been proposed. The performance matrices obtained from drive test are co-analyzed in cooperation with throughput data obtained from base stations. The results indicate that the prospective areas of interference problem can be predicted using the proposed method. Also the limitation of cell throughput can be pointed out in order that the operators can arrange the appropriate plan to upgrade their networks.
