5G slicing and S-NSSAI

Network Slicing is considered as one of the key feature by 3GPP in 5G.  A network slice can be looked as a logical end-to-end network that can be dynamically created. A UE may access to multiple slices over the same gNB. Each slice may serve a particular service type with agreed upon Service-level Agreement (SLA).

To uniquely identify a  Network Slice, the 5G system defines the S-NSSAI (Single – Network Slice Selection Assistance Information).

S-NSSAI is made up of two field SST (Slice/Service Type) and SD (Service Differentiator). SD is an optional field. SST has 8 bit field length implying that it can indicates a total of 255 different slice types.

  1. SST (Slice/Service Type) – this will define the expected behaviour of the Network Slice in terms of specific features and services, such as V2X. The standard SST values are highlighted below :
Slice/Service Type SST Value Characteristics
eMBB 1 Slice suitable for the handling of 5G enhanced Mobile Broadband
URLLC 2 Slice suitable for the handling of ultra- reliable and low latency communications
MIoT 3 Slice suitable for the handling of massive IoT
V2X 4 Slice suitable for the handling of V2X services
HMTC 5 Slice suitable for the handling of High-Performance Machine-Type Communications

 

2) SD (Slice Differentiator) – this is optional information that complements the Slice/Service type and is used as an additional differentiator if multiple Network Slices carry the same SST value
