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.

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].
