Standardized SST values provide a way for establishing global interoperability for slicing so that PLMNs can support the roaming use case more efficiently for the most commonly used Slice/Service Types.
The SSTs which are standardised are in the following Table 5.15.2.2-1.
Table 5.15.2.2-1: Standardised SST values
| 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 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. |
| HDLLC | 6 | Slice suitable for the handling of High Data rate and Low Latency Communications. |
| GBRSS | 7 | Slice suitable for the handling of Guaranteed Bit Rate Streaming Service. |
NOTE 1: The support of all standardised SST values is not required in a PLMN. Services indicated in this table for each SST value can also be supported by means of other SSTs.
NOTE 2: A mapping of GSMA defined Network Slice Types (NEST) to standard SST values is defined in GSMA NG.116 [137].
