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.4A, Figure 9.11.3.53A.4B, 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.

The UE security capability information element is used by the UE and by the network to indicate which security algorithms are supported by the UE in N1 mode for NAS security as well as which security algorithms are supported over NR and E-UTRA connected to 5GCN for AS security. The UE security capability information element is coded as shown in Figure 9.11.3.54.1 and Table 9.11.3.54.1. The UE security capability is a type 4 information element with a minimum length of 4 octets and a maximum length of 10 octets. Octets 5 to 10 are optional. If octet 5 is included, then also octet 6 shall be included. If the UE does not support any security algorithm for AS security over E-UTRA connected to 5GCN, it shall not include octets 5 and 6. The UE shall not include octets 7 to 10. If the UE does not support any security algorithm for AS security over E-UTRA connected to 5GCN, and if the network includes octets 7 to 10, then the network shall also include octets 5 to 6. If the network includes octet 7, then it shall include also octet 8. If the network includes octet 9, then it shall include also octet 10.

The purpose of the UE's usage setting information element is to provide the network with the UE's usage setting as defined in TS 24.301. The network uses the UE's usage setting to select the RFSP index. The UE's usage setting information element is coded as shown in Figure 9.11.3.55.1 and Table 9.11.3.55.1. The UE's usage setting is a type 4 information element with a length of 3 octets.

The purpose of the UE status information element is to provide the network with information concerning aspects of the current UE registration status which is used for interworking with EPS. The UE status information element is coded as shown in Figure 9.11.3.56.1 and Table 9.11.3.56.1. The UE status is a type 4 information element with a length of 3 octets.

The purpose of the Uplink data status information element is to indicate to the network which preserved PDU session(s) have uplink data pending or which preserved PDU session(s) are associated with active multicast MBS session(s). The Uplink data status information element is coded as shown in Figure 9.11.3.57.1 and Table 9.11.3.57.1. The Uplink data status information element is a type 4 information element with minimum length of 4 octets a maximum length of 34 octets.
