Amf to Nssf NF Tab

The Amf to Nssf NF (Network Function) Consumer tab is available when Test NSSF (Nnssf), From AMF (N22) is selected on Service Based Nodal test case and when N22 interface is enabled on AMF Node Emulator Configuration. About the 5G Application.

TS 23.501 defines Network Function, Slice, and Slice Instance as follows:

Network Function: A 3GPP adopted or 3GPP defined processing function in a network, which has defined functional behavior and 3GPP defined interfaces. (Note: A network function can be implemented either as a network element on a dedicated hardware, as a software instance running on a dedicated hardware, or as a virtualized function instantiated on an appropriate platform, e.g. on a cloud infrastructure.)

Network Slice: A logical network that provides specific network capabilities and network characteristics.

Network Slice Instance: A set of Network Function instances and the required resources (e.g. compute, storage and networking resources) which form a deployed Network Slice.

Per 3GPP TS 23.501, 23.502 and 29.5xx.

Network Slice Selection Request Info

Enable Slice Info for Registration

Select Enable Slice Info for Registration to enter the Network Slice Selection Request Info. Identification of a Network Slice is done via the Single Network Slice Selection Assistance Information (S-NSSAI). The NSSAI (Network Slice Selection Assistance Information) is a collection of S-NSSAIs. Currently 3GPP allows up to eight (8) S-NSSAIs in the NSSAI sent in signaling messages between the UE and the Network. This means a single UE may be served by at most eight Network Slices at a time. The S-NSSAI signaled by the UE to the network, assists the network in selecting a particular Network Slice instance.

When Nnssf Version (29.531) is > 15.2.0, Enable Slice Info Selection Update becomes available.
