9.11.4.18 5GSM network feature support
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 5GSM network feature support information element is to indicate whether certain session management related features are supported by the network.
The 5GSM network feature support information element is coded as shown in figure 9.11.4.18.1 and table 9.11.4.18.1.
The 5GSM network feature support is a type 4 information element with a minimum length of 3 octets and a maximum length of 15 octets.
