Value part of the LADN indication information element (octet 4 to h): | |
The value part of the LADN indication information element consists of zero or more LADN DNN values. If the LADN indication information element conveys more than 8 LADN DNN values in this information element, the network shall consider the first 8 LADN DNN values and ignore the remaining octets of the information element. | |
LADN DNN value: | |
LADN DNN value is coded as the length and value part of DNN information element as specified in subclause 9.11.2.1B starting with the second octet. | |
Value part of the LADN information information element (octet 4 to octet h) | |
The value part of the LADN information information element consists of one or several LADNs. Each LADN (e.g. octet 4 to octet a) consists one DNN value and one 5GS tracking area identity list. The length of each LADN is determined by the length of DNN value field and the length of 5GS tracking area identity list field. The UE shall store the complete list as received. If more than 8 LADNs are included in this information element, the UE shall store the first 8 LADNs and ignore the remaining octets of the information element. | |
DNN value (octet 5 to octet m): | |
DNN value field is coded as DNN value part of DNN information element as specified in subclause 9.11.2.1B starting with the third octet. | |
5GS tracking area identity list (octet m+1 to octet a): | |
5GS tracking area identity list field is coded as the length and the value part of the 5GS Tracking area identity list information element as specified in subclause 9.11.3.9 starting with the second octet. | |
Registration Area Allocation Indication (RAAI) (octet 1, bit 1) | |
In the network to UE direction: | |
0 | all PLMN registration area not allocated |
1 | all PLMN registration area allocated |
In the UE to network direction bit 1 is spare. The UE shall set this bit to zero. | |
Strictly Periodic Registration Timer Indication (SPRTI) (octet 1, bit 2) | |
In the network to UE and the UE to network direction: | |
0 | strictly periodic registration timer not supported |
1 | strictly periodic registration timer supported |
Bits 3 and 4 are spare and shall be coded as zero. | |
NOTE:
In the network to UE direction in the CONFIGURATION UPDATE COMMAND message, bits 1 and 2 shall be coded as zero.
|
MA PDU session information value (octet 1, bit 1 to bit 4) | |
Bits
4 3 2 1 | |
0 0 0 0 | No additional information |
0 0 0 1 | MA PDU session network upgrade is allowed |
All other values are spare. If received they shall be ignored. | |
Value part of the Mapped NSSAI information element (octet 3 to v) | |
The value part of the Mapped NSSAI information element consists of one or more mapped S-NSSAI contents. Mapped S-NSSAI content: | |
Length of S-NSSAI contents (octet 3) | |
Mapped HPLMN Slice/service type (SST) (octet 4) | |
This field contains the 8 bit SST value of an S-NSSAI in the S-NSSAI(s) of the HPLMN to which the SST value is mapped. The coding of the SST value part is defined in TS 23.003. | |
Mapped HPLMN Slice differentiator (SD) (octet 5 to octet 7) | |
This field contains a 24-bit SD value of an S-NSSAI in the S-NSSAI(s) of the HPLMN to which the SD value is mapped. The coding of the SD value part is defined in TS 23.003. | |
Type of security context flag (TSC) (octet 1) | |
Bit
4 | |
0 | native security context (for KSIAMF) |
0 | mapped security context (for KSIASME) |
TSC does not apply for NAS key set identifier value "111". | |
NAS key set identifier (octet 1) | |
Bits
3 2 1 | |
0 0 0
through 1 1 0 | possible values for the NAS key set identifier |
1 1 1 | no key is available (UE to network);
reserved (network to UE) |
