Network Slice Selection Policy

NSSF allows the operator to configure network slice selection policies. Following diagram illustrates the Policy configuration.

Figure 1-1 Policy Configuration

NSSF Policy is a set of dynamic policy rules which enables NSSF to select and update Network slice mapping and availability status on time. The operator can configure policy rules such that an NSSelection request coming from a given AMF having a given PLMN and/or TAC and containing a given S-NSSAI that is both requested and subscribed can be either allowed for a certain Access Type with certain Network Slice Profile(s) or can be restricted at the PLMN or TA. The AMF, PLMN, and TAC can be configured as Don't Cares to enable policies to span geographies.
