9.11.3.85 PLMN identity
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 PLMN identity information element is to provide a PLMN identity.
The PLMN identity information element is coded as shown in figure 9.11.3.85.1, and table 9.11.3.85.1.
The PLMN identity is a type 4 information element.
| 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | |
|---|---|---|---|---|---|---|---|---|
| PLMN identity IEI | octet 1 | |||||||
| Length of PLMN identity contents | octet 2 | |||||||
| MCC digit 2 | MCC digit 1 | octet 3 | ||||||
| MNC digit 3 | MCC digit 3 | octet 4 | ||||||
| MNC digit 2 | MNC digit 1 | octet 5 |

Table 9.11.3.85.1: PLMN identity information element
| MCC, Mobile country code (octet 3, octet 4 bits 1 to 4) |
|---|
| The MCC field is coded as in ITU-T Recommendation E.212 [42], annex A. |
| MNC, Mobile network code (octet 4 bits 5 to 8, octet 5) |
| 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 4 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]. |
