Realizing 5G Network Slicing Provisioning with Open Source Software

5G has gradually been commercialized in countries around the world, but for most telecom companies, network slicing is still in the development stage and has not been applied to appropriate scenarios. Automated provisioning of network slicing is even more challenging for development. The purpose of this research is to implement a complete, open source, and automatically deployable 5G network slicing architecture. We use OpenStack as the platform required to realize virtualization, Tacker module for slicing environment deployment, free5GC as the core network of the 5G system, and UERANSIM as the role of simulating UE and gNB. Through the proposed architecture, an automatic slicing service with specific functions can be created, the slice can be registered into the 5G network with the support of the core network, and the simulated UE can be used to connect the related slice. Experimental results show that the proposed open-source-based architecture is feasible and the QoS is guaranteed for each slice.
