9.11.3.92 SNPN list

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 SNPN list information element is to provide a list of SNPN identities.

The SNPN list information element is coded as shown in figure 9.11.3.92.1, table 9.11.3.92.1, figure 9.11.3.92.2 and table 9.11.3.92.2.

The SNPN list is a type 4 information element with a minimum length of 11 octets and a maximum length of 137 octets.

Each SNPN identity field is coded according to figure 9.11.3.92.2 and table 9.11.3.92.2.

Table 9.11.3.92.2: SNPN identity i

MCC, Mobile country code (octet (i*9-6), octet (i*9-5) bits 1 to 4)
The MCC field is coded as in ITU-T Recommendation E.212 [42], annex A.
MNC, Mobile network code (octet (i*9-5) bits 5 to 8, octet (i*9-4))
The coding of this field is the responsibility of each administration but BCD coding shall be used. The MNC shall consist of 2 or 3 digits. If a network operator decides to use only two digits in the MNC, bits 5 to 8 of octet 6 shall be coded as "1111"
The MCC and MNC digits are coded as octets 6 to 8 of the Temporary mobile group identity IE in figure 10.5.154 of 3GPP TS 24.008 [12].
NID (octet (i*9-3) to octet (i*9+2))
NID field is coded as the NID field of NID IE as specified in figure 9.2.7-2 and table 9.2.7-2 of 3GPP TS 24.502 [18] starting with the octet 3 and ending with the octet 8.
