Figure 8.136-1: Extended Trace Information

Octets 5 to 10 represent the Trace Reference parameter as defined in clause 5.6 of 3GPP TS 32.422 [18].

Triggering Events, List of NE Types, Session Trace Depth, List of Interfaces and IP Address of Trace Collection Entity are specified in 3GPP TS 32.422 [18].

NOTE: The List of Triggering Events, List of NE Types and List of Interfaces include the events, NE types and List of interfaces to be traced in the target system during an EPS to 5GS or 5GS to EPS mobility, see clause 4.1.2.15.2 of 3GPP TS 32.422 [18].

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".
