Q2 - Visibility on all relevant procedures (both control plane on S1, S10, S11 and S5/S8 and User Plane on S5/S8), as well as key recovery for NAS de-ciphering (S6a).
Q4- Additional interfaces will become important later as different QoS levels will be implemented (Gx) as well as Rel 8 handover (S3, S4). S9 PCRF-PCRF will also be supported for LTE Roaming.

Roaming Problem Identification: exampleThis statistic
provides all the reasons why
roaming wasn’t successful
A Trace filter can be applied directly from the
statistic page
Some “Roaming not allowed”needs further investigation
Roaming Problem Identification: example
By opening the Trace page the user
immediately gets all the filtered frames
Clicking on a frame it is possible to recover
the related CDR
Roaming Problem Identification: example
The first digits of the IMSI identifies the Operator of the end-user
Usability - Filters

Filter Setup
� Filter Templates� Filters can be applied and saved even if no value has been assigned� Filters with no values can be saved in a library as well; hence a user can create
its own templates� The same Filter can be applied twice in the same “AND” group
32
Filter Setup
� Add Time Search option: delimit the search of frames or CDRs in a limited time frame to reduce Search waiting (From/To filter)
