Abstract- – This research focuses on the mobility management technique of network slicing in 5G networks. Network slicing involves dividing the physical network infrastructure into multiple virtual networks called network slices, each optimized for specific applications or use cases. Network slice handover enables seamless transfer of a user’s connection between different network slices without interrupting the quality of service. The research aims to analyze and develop an algorithm for making network slice handover decisions in segmented 5G networks and evaluate its performance. The research proposes an algorithm for network slice handover delivery decisions based on an analytic model using Markov chain. The network model’s architecture and the implementation of the vertical delivery decision-making algorithm are described. The performance of the algorithm is evaluated using key performance indicators (KPIs) related to quality of service at the connection level, such as the likelihood of new calls being blocked, or connections being lost. Simulations are conducted to assess how changes in metrics, such as contact arrival rate, capability, new call threshold, base bandwidth unit, and call departure rate, impact the quality-of-service measurements. The simulation results show that the developed algorithm generally provides good quality of service levels, with a lower likelihood of dropping a distribution call compared to new calls being blocked in all cases. The research contributes to the understanding and improvement of network slice handover in 5G networks by proposing an algorithm and evaluating its performance through simulations. The results demonstrate the algorithm’s effectiveness in maintaining quality of service during network slice handover.
