An Adaptive Auto-Tuning Scheme Based Mobility in 4G and Beyond Networks

Self-Organizing Network, or SON, is a new technology that aims to minimize human efforts spent in management and operating processes. In technical term; this solution was proposed to reduce the operational expenditure for service providers in future wireless systems since it offers the possibility of automatic and remote managing of mobile networks especially in LTE-Advanced and beyond, coming within the 11th Release of 3GPP. SON includes a set of functions divided into three types: self-configuration, self-optimization and self-healing functions. Some of these functions have already been standardized but others still under researches, since they present some problems such as auto-tuning mobility parameters, which is the main topic that will be discussed throughout this work. Thus, we will try in this paper to find solutions to achieve traffic balancing and enhance the network capacity by developing a novel auto-tuning strategy based on mobility. This strategy will present the impact of LTE-A and mobility auto-tuning on the system performances, defined as the user throughput average and congestion indicators of the network. At the end simulation results demonstrate that the gain capacity when using the auto-tuning concept is further greater than without it.
