Trace Reference shall be coded as depicted in Figure 8.45-1. See 3GPP TS 32.422 [18], clause 5.6, for the definition of Trace Reference.

See 3GPP TS 24.008 [5], clause 10.5.1.4, Mobile Identity, for the coding of MCC and MNC, whose values are obtained from the serving PLMN that the EM/NM is managing. If MNC is 2 digits long, bits 5 to 8 of octet 6 are coded as "1111".
