Editing My 3GPP 24.501 notes (section)

== 9.11	Other information elements ==

=== 9.11.1 General ===

<span style="color:red">The different formats (V, LV, T, TV, TLV, LV-E, TLV-E) and the five categories of information elements (type 1, 2, 3, 4 and 6) are defined in 3GPP TS 24.007.</span>

The first octet of an information element in the non-imperative part contains the IEI of the information element. If this octet does not correspond to an IEI known in the message, the receiver shall determine whether this IE is of type 1 or 2 (i.e., it is an information element of one octet length) or an IE of type 4 (i.e., that the next octet is the length indicator indicating the length of the remaining of the information element) (see 3GPP TS 24.007).

This allows the receiver to jump over unknown information elements and to analyze any following information elements of a particular message.

The definitions of information elements which are:
<ol type="a">
<li>common for the 5GMM and 5GSM protocols;</li>
<li>used by access stratum protocols; or</li>
<li>sent to upper layers</li>
</ol>
are described in subclause 9.11.2.

The information elements of the 5GMM or 5GSM protocols can be defined by reference to an appropriate specification which provides the definition of the information element, e.g., "see subclause 10.5.6.3A in 3GPP TS 24.008".

=== 9.11.3 5GS mobility management (5GMM) information elements ===

See spec for details...

==== <span style="color:red">9.11.3.4 5GS mobile identity</span> ====

<span style="color:red">The purpose of the 5GS mobile identity information element is to provide either the SUCI, the 5G-GUTI, the IMEI, the IMEISV, the 5G-S-TMSI, the MAC address or the EUI-64.</span>

The 5GS mobile identity information element is coded as shown in figures 9.11.3.4.1, 9.11.3.4.2, 9.11.3.4.3, 9.11.3.4.4, 9.11.3.4.5, 9.11.3.4.6, 9.11.3.4.8 and 9.11.3.4.7, and table 9.11.3.4.1.

The 5GS mobile identity is a type 6 information element with a minimum length of 4.
