Network slice access selection scheme in 5G

The demand and scene of 5G network are diverse, and different scenes have different requirements for the function and performance of the network. On the basis of the traditional single network, the continuous fusion and optimization can't meet the diverse needs of 5G networks, and some optimizations and requirements may be contradictory in different scenarios. The introduction of network section in 5G network, different slices can be defined for different needs of the scene, but also share the same infrastructure, so as to achieve the full utilization of resources and meet the different demand scenarios. In this paper, we propose a network slicing architecture and propose a network slicing access selection method based on this architecture. It not only optimizes the performance of the network and maximizes resource utilization, but also shortens the creation time of the slice.
