Design and Experimental Validation of a Software-Defined Radio Access Network Testbed with Slicing Support
Table 1
3GPP defined attributes for network slicing configuration.
NSSI NRM (SliceProfile class)
Attribute
Explanation
SliceProfileId
A unique identifier of the slice profile.
SNSSAI
Set of supported S-NSSAI(s) in the NSSI. Each S-NSSAI is comprised of a SST (Slice/Service type) and an optional SD (Slice Differentiator) field.
PLMNId
Set of PLMN(s) associated with the NSSI.
PerfReq
It specifies the requirements to the NSSI in terms of the scenarios defined in the TS 22.261, such as experienced data rate, and area traffic capacity (density) of UE density. Limitation of the attribute values is not addressed.
maxNumber ofUEs
It specifies the maximum number of UEs that may simultaneously access the NSSI.
coverageArea TAList
List of tracking area(s) where the NSSI can be selected.
Latency
It specifies the packet transmission latency (millisecond) through the RAN, CN, and TN part of 5G network
UEMobility Level
It specifies the mobility level of a UE accessing the NSSI. Allowed values: stationary, nomadic, restricted mobility, and fully mobility.
Resource SharingLevel
It specifies whether the resources to be allocated to the network slice instance may be shared with another network slice instance(s). Allowed values: shared, non-shared.
NR and NG-RAN (gNB) NRM
Attribute
Explanation
SNSSAI
Set of supported S-NSSAI(s).
RRMPolicy
Represents the RRM policy, which includes guidance for split of radio resources between multiple slices the cell supports. The RRM policy is implementation dependent.
