29.0603GPPGeneral Packet Radio Service (GPRS)GPRS Tunnelling Protocol (GTP) across the Gn and Gp interfaceRelease 17TS
The additional Trace Info is used to inform the GGSN of the additional trace parameters. An Additional Trace Info consists of Trace Reference2, Trace Recording Session Reference, triggering events in GGSN, Trace Depth, List of interfaces to trace in GGSN and a Trace Activity Control.
