Section: 24.2.3 Format of PLMN ID in ProSe Application ID
Content: The PLMN ID shall uniquely identify the PLMN of the ProSe Function that has assigned the ProSe Application ID. The PLMN ID is composed of two labels which shall be separated by a dot as follows: "mcc<MCC>.mnc<MNC>" where: "mcc" and "mnc" serve as invariable identifiers for the following digits. <MCC> contains the MCC (Mobile Country Code) of the ProSe Function that has assigned the ProSe Application ID. <MNC> contains the MNC (Mobile Network Code) of the ProSe Function that has assigned the ProSe Application ID. In order to guarantee inter-PLMN operability, the <MCC> and the <MNC> shall be represented by 3 digits. If there are only 2 significant digits in the MNC, one "0" digit is inserted at the left side of the MNC to form the <MNC> in the "mnc<MNC>" label. EXAMPLE: The PLMN ID for MCC 345 and MNC 12 will be "mcc345.mnc012".
