Figure 8.2.108-1: Trace Information
Octets 5 to 10 represent the Trace Reference parameter as defined in clause 5.6 of 3GPP TS 32.422 [35].
Triggering Events, Session Trace Depth, List of Interfaces and IP Address of Trace Collection Entity are specified in 3GPP TS 32.422 [35].
Octets "(p+2) to q" shall contain an IPv4 address value (4 octets) or IPv6 address value (16 octets).
See 3GPP TS 24.008 [5], clause 10.5.1.4, Mobile Identity, for the coding of MCC and MNC. If MNC is 2 digits long, bits 5 to 8 of octet 6 are coded as "1111".
