Multimedia Wireless Networks (ET5907701) Iwan Setiawan (stwn at unsoed.ac.id) Network Slice (NS) Terms ● NS Selection Funct. (NSSF): NF to select NSI serving the UE ● NS Template (NST): logical NFs and resources linked to the services and network capabilities required* ● NS Instance (NSI): an NS instance created fom NST ● NS Selection Assistance Information (NSSAI) – Slice/Service Type (SST): eMBB (1), uRLLC (2), mMTC (3)** – Slice Differentiator (SD): additional differentiator if multiple network slices carry the same SST value * 3GPP TS 23.501 * https://mpirical.com/glossary

Conclusions 

Multimedia Wireless Networks (ET5907701) Iwan Setiawan (stwn at unsoed.ac.id) Concluding Remarks ● 5GC uses SDN and NFV in the SBA to support network slicing for multi use cases ● NFs in 5GC can be created dynamically to provide network slice for each use case ● Each network slice has different set of NFs, and it can share set of NFs with other slices
