3GPP 24.501 v20.0.0 — the document's own text
9.11.3.53A UE parameters update transparent container
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 UE parameters update transparent container when sent from the network to the UE is to provide UE parameters update data, optional acknowledgement request and optional re-registration request. The purpose of the UE parameters update transparent container when sent from the UE to the network is to indicate the UE acknowledgement of successful reception of the UE parameters update transparent container.
The UE parameters update transparent container information element is coded as shown in figure 9.11.3.53A.1, figure 9.11.3.53A.2, figure 9.11.3.53A.3, figure 9.11.3.53A.4, figure 9.11.3.53A.4B, figure 9.11.3.53A.4C, figure 9.11.3.53A.5, figure 9.11.3.53A.6, figure 9.11.3.53A.7 and table 9.11.3.53A.1.
The UE parameters update transparent container is a type 6 information element with a minimum length of 20 octets.

| 0 1 0 1 Protected UE parameters update header information (NOTE 5) | |
| All other values are reserved | |
| Disaster Roaming Enabled Indication (DREI) value (octet d*, bit 1) | |
| 0 | Disaster roaming is disabled in the UE |
| 1 | Disaster roaming is enabled in the UE |
| Indication of 'applicability of "lists of PLMN(s) to be used in disaster condition" provided by a VPLMN' (AOL) value (octet d*, bit 2) | |
| 0 | false |
| 1 | true |
| Disaster Roaming Enabled Indication in EPS (DREIEPS) value (octet d*, bit 3) | |
| 0 | Disaster roaming in EPS is disabled in the UE |
| 1 | Disaster roaming in EPS is enabled in the UE |
| The secured packet is coded as specified in 3GPP TS 31.115 [22B]. | |
| The default configured NSSAI is encoded as the value part of the NSSAI IE (see clause 9.11.3.37). | |
| Routing indicator | |
| Routing indicator is encoded as the routing indicator field of the 5GS mobile identity IE (see clause 9.11.3.4). | |
| NOTE 1: When the routing indicator is updated, if the SNPN uses the EAP based primary authentication and key agreement procedure using the EAP-AKA' or the 5G AKA based primary authentication and key agreement procedure, then UE parameter update data set type is set to "routing indicator update data", otherwise, UE parameter update data set type is set to "ME routing indicator update data".NOTE 2: The UPU data type set to "0" is used in the network to UE direction. The UPU data type set to "1" is used in the UE to network direction.NOTE 4: In the UE parameters update data set with the UE parameters update data set type indicating "protected UE parameters update header information", the UPU data type shall be set to "0".NOTE 5: If the UE supports UE parameters update header protection and the UE parameters update list includes a UE parameters update data set with the UE parameters update data set type indicating "protected UE parameters update header information", then the UE uses header information from the UE parameters update data set with the UE parameters update data set type indicating "protected UE parameters update header information". |
