An Efficient RF Self Optimization Tool (SOT) for 4G/5G Mobile Communication

With the rapid growth of mobile networks, maintenance is becoming more complex, time-consuming, and expensive. One of the most important requirements of network operators and service providers is network optimization. Network optimization is one of the key parts of the life cycle of mobile systems. In this paper, a design of RF Self Optimization Tool called (SOT) for a 4G/5G network is introduced. In particular, an optimization framework is developed considering different stages that include the collection of data inputs from different sources, the description of all Key Performance Indicators (KPI's) categories, and the optimization procedure itself. It enables faster measurements and response for the statues of the 4G/5G networks by offering the actions that should be taken automatically to optimize the network and to be gained for performance issues. The proposed design is applied and the performance is evaluated illustrating the capability to automatically identify a cell with sub-optimal coverage and to provide solutions to these problems to meet QoS requirements.
