9.11.3.83 List of PLMNs to be used in disaster condition

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 list of PLMNs to be used in disaster condition information element is to provide the "list of PLMN(s) to be used in disaster condition" associated with the serving PLMN to the UE.

The list of PLMNs to be used in disaster condition information element is coded as shown in figures 9.11.3.83.1 and 9.11.3.83.2 and table 9.11.3.83.1.

The list of PLMNs to be used in disaster condition is a type 4 information element, with a minimum length of 2 octets.

MCC, Mobile country code (octet q+1 and bits 1 to 4 octet q+2)The MCC field is coded as in ITU-T Recommendation E.212 [42], annex A.
MNC, Mobile network code (bits 5 to 8 of octet q+2 and octet q+3)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 q+2 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].
NOTE: The PLMN IDs are provided in decreasing order of priority, i.e. PLMN ID 1 indicates highest priority and PLMN ID n indicates lowest priority.
