Section: 24.3.3 Format of temporary identity in ProSe Application Code
Content: The temporary identity in the ProSe Application Code is a bit string whose value is allocated by the ProSe Function. The length of the temporary identity in the ProSe Application Code is equal to: - 180 bits when the E bit of the PLMN ID in the ProSe Application Code is set to 0. - 160 bits when the E bit of the PLMN ID in the ProSe Application Code is set to 1. The temporary identity in the ProSe Application Code shall contain a metadata index to reflect the current metadata version if dynamic metadata is used when allocating the ProSe Application Code. The content, position and length of metadata index is operator specific. In this release, the MCC and the MNC of the ProSe Function that has assigned the ProSe Application Code are always included in the PLMN ID in ProSe Application Code. The length of the temporary identity in the ProSe Application Code shall always be equal to 160 bits.
