9.11.3.99 Non-3GPP access path switching 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 Non-3GPP access path switching indication information element is to indicate whether the UE supports the non-3GPP access path switching for the PDU session.
The Non-3GPP access path switching indication information element is coded as shown in figure 9.11.3.99.1 and table 9.11.3.99.1.
The Non-3GPP access path switching indication is a type 4 information element with a length of 3 octets.
