| dc.description.abstract | In GSM communications, congestion remains a major factor and stands as a high influence in the satisfaction of subscribers and service providers[1]. Traffic Channel (TCH) and Standalone Dedicated Control Channel (SDCCH) Congestions are two major problems faced in GSM networks. This thesis attempted to investigate the causes of SDCCH & TCH congestions, and the assessment of the current state of GSM networks in Liberia by using a Liberian GSM network‟s KPI (key Performance indicator) as case study to develop an optimized GSM network model. During the sampling and processing of the data in the investigation, a range of 49-0% was chosen as the worst call setup success rate (WCSSR). These WCSSR locations along with their various SDCCH & TCH congestion results were later plotted into bar chart graphs, and point graphs using OriginPro software. Finally, a Sugeno-Takagi KPI Optimization simulation setup was developed using Adaptive Network Fuzzy Inference System (ANFIS) model in MATLAB. The simulations compares and demonstrates the current and expected optimized network. The result shows that optimization is possible and can be almost at the maximum level in real cellular networks. | en_US |
