▀ Subscriber Session Trace Functional Description
(specific decoded IEs) to be traced and forwarded. The contents and definition of the medium and minimum trace can
be found in 3GPP standard 3GPP TS 32.423 V8.2.0 (2009-09).
Important:

Trace Scope

The Trace Scope defines what NEs and what interfaces have the tracing capabilities enabled on them. This is actually a
specific list of NE types and interfaces provided in the trace session configuration by the operator (either directly via a
management interface or indirectly via a signaling interface).

Network Element Details

Trace functionality for each of the specific network elements supported by this functionality are described in this
section.
This section includes the trace monitoring points applicable to them as well as the interfaces over which they can send
and/or receive trace configuration.

MME
