9.11.4.41 Non-3GPP device information

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 device information information element is to provide one or more non-3GPP device identifiers for which QoS differentiation of traffic is requested or for which suspend of QoS differentiation of traffic is requested.

The Non-3GPP device information information element is coded as shown in figure 9.11.4.41.1, figure 9.11.4.41.2, figure 9.11.4.41.3, figure 9.11.4.41.4, figure 9.11.4.41.5, figure 9.11.4.41.6, and table 9.11.4.41.1.

The Non-3GPP device information information element is a type 6 information element with minimum length of 7 octets.
