9.11.3.36 Network slicing indication
Taught in 4. Inside TS 24.501, the document at the centre (CT1 — the group that writes what your phone says, overview).
The purpose of the Network slicing indication information element is to indicate additional information associated with network slicing in the generic UE configuration update procedure and the registration procedure, other than the user's configured NSSAI, allowed NSSAI, pending NSSAI and rejected NSSAI information.
The Network slicing indication information element is coded as shown in figure 9.11.3.36.1 and table 9.11.3.36.1.
The Network slicing indication is a type 1 information element.
