12.083GPPSubscriber and equipment traceTS
The present document specifies the Trace facility for GSM where it refers to:
‑ subscriber tracing (tracing of International Mobile Subscriber Identity (IMSI));
‑ equipment tracing (tracing of International Mobile station Equipment Identity (IMEI)).
It does not cover:
‑ types of trace which relate more to network elements than to individual subscribers e.g. tracing events within a Base Station System (BSS), and so on;
‑ tracing of all possible parties in e.g. a multi‑party call.
It also refers only to tracing activated from the OSF and not to that activated by means of local Man Machine Interface (MMI).
