Performance Evaluation of Mobility Robustness Optimization (MRO) in 5G Network With Various Mobility Speed Scenarios

The massive deployment of small-sized cells for the Fifth Generation (5G) mobile network will increase Handover Probability (HOP), potentially causing higher Ping-Pong (HPPP) and/or Radio Link Failure (RLF). Inappropriate usage Control Parameter (HCP) settings may further exasperate this issue. Therefore, Mobility Robustness Optimisation (MRO) has been introduced and developed as a significant Self-Optimisation Network (SON) function in 5G beyond. main aim MRO is to address Management (MM) issues during user mobility between ensure smooth connection. Although various algorithms were suggested literature, they mostly cater 4G networks which not be effective due different characterisations. This paper analyses performance with system scenarios network. investigated from literature include Distance (Dis), Cost Function (CF), Fuzzy Logic Controller (FLC) Performance Indicator (HPI). Validation accomplished conditions A simulation based on MATLAB software conducted using tools. evaluation analysis terms Signal to-Interference-plus-Noise-Ratio (SINR), HPPP RLF effects since these are major indicators assessing selecting handover decision mobility. outcomes show that HPI algorithm more reactive speed over time, significantly reducing compared other do provide large reactions same conditions. Simultaneously, exhibits highest SINR among algorithms. distance best SINR, achieving an acceptable level HPPP. These results point operate most robust algorithms, confirming potential Dis approach
