9.11.3.82 NSSRG 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 NSSRG information information element is to identify one or more NSSRG values associated with each of the HPLMN S-NSSAIs in a configured NSSAI.

The NSSRG information information element is coded as shown in figure 9.11.3.82.1, figure 9.11.3.82.2 and table 9.11.3.82.1.

The NSSRG information is a type 6 information element with minimum length of 7 octets and maximum length of 4099 octets.

Value part of the NSSRG information information element (octet 4 to v)The value part of the NSSRG information information element consists of one or more NSSRG values for each S-NSSAI in the Configured NSSAI IE.S-NSSAI value (octet 5 to w) (see NOTE 2)S-NSSAI value is coded as the length and value part of S-NSSAI information element as specified in clause 9.11.2.8 starting with the second octet. See NOTE 1.
NSSRG value for the S-NSSAI (octet w+1)
This field contains the 8 bit NSSRG value.
NOTE 1: If a mapped HPLMN SST is included in a S-NSSAI value, then the NSSRG value(s) are associated with the Mapped HPLMN SST, and the Mapped HPLMN SD, if included.NOTE 2: The NSSRG information IE shall contain the complete set of S-NSSAI(s) included in the configured NSSAI.NOTE 3: The number of NSSRG values associated with an S-NSSAI cannot exceed 16. If there are more than 16 NSSRG values for an S-NSSAI in the NSSRG information, then the UE shall retain only the first 16 NSSRG values and ignore the rest.
