The handover process introduces new and complex challenges in the 5G/Beyond 5G (B5G) wireless networks. Unlike previous generations, users in 5G/B5G networks do not only transit between different base stations or access technologies but also across various Network Slices (NSs). These slices are selected based on the user’s specific requirements and preferences. Therefore, the constraints on NS must be taken into account to ensure that handover decisions adequately satisfy user demands. This paper proposes a fuzzy-based system for handover management, incorporating four parameters: Slice Delay (SD), Slice Bandwidth (SB), Slice Stability (SS), and Slice Active Time (SAT), which is a new parameter. The simulation results indicate that these parameters have different impacts on the Handover Decision (HD). The increase of SD leads to the increase of the HD parameter, while the increase of SB, SS and SAT values leads to the decrease of HD value.

摘要

The handover process introduces new and complex challenges in the 5G/Beyond 5G (B5G) wireless networks. Unlike previous generations, users in 5G/B5G networks do not only transit between different base stations or access technologies but also across various Network Slices (NSs). These slices are selected based on the user’s specific requirements and preferences. Therefore, the constraints on NS must be taken into account to ensure that handover decisions adequately satisfy user demands. This paper proposes a fuzzy-based system for handover management, incorporating four parameters: Slice Delay (SD), Slice Bandwidth (SB), Slice Stability (SS), and Slice Active Time (SAT), which is a new parameter. The simulation results indicate that these parameters have different impacts on the Handover Decision (HD). The increase of SD leads to the increase of the HD parameter, while the increase of SB, SS and SAT values leads to the decrease of HD value.
