In 5G and beyond (B5G) networks, handover management is a challenging task due to the complexity of optimizing decisions in dynamic and heterogeneous environments. Factors like user mobility, diverse service requirements, and multiple access technologies make handover optimization an NP-hard problem. To address these challenges, this paper introduces a Fuzzy-based Handover system for 5G and B5G wireless networks considering four key parameters: Slice Stability (SS), Slice Active Time (SAT), Slice Reliability (SR), and Radio Access Technology Condition (RATC), with RATC being a new parameter. The simulation results show that by increasing SS, SAT, SR and RATC, the probability of initiating HD decreases. The enhanced stability, greater slice reliability, longer slice activity and improved radio access technology conditions contribute to a more stable network connection and reduced handover events.

摘要

In 5G and beyond (B5G) networks, handover management is a challenging task due to the complexity of optimizing decisions in dynamic and heterogeneous environments. Factors like user mobility, diverse service requirements, and multiple access technologies make handover optimization an NP-hard problem. To address these challenges, this paper introduces a Fuzzy-based Handover system for 5G and B5G wireless networks considering four key parameters: Slice Stability (SS), Slice Active Time (SAT), Slice Reliability (SR), and Radio Access Technology Condition (RATC), with RATC being a new parameter. The simulation results show that by increasing SS, SAT, SR and RATC, the probability of initiating HD decreases. The enhanced stability, greater slice reliability, longer slice activity and improved radio access technology conditions contribute to a more stable network connection and reduced handover events.
