When checking Gb over IP -trace, I need to first use the decode as NSIP to get
wireshark to show the Gb-signalling.
After that, when I try to set the filter with most fields on BSSGP-layer (e.g.
using right-click and "prepare filter...selected", I'll get definately wrong
filters. I've tried to manually create those filters as well and they don't
work. However at least bssgp.tmsi_ptmsi and bssgp.pdu_type works.
Here are some examples which don't work properly:
Should be prepare filter...selected
bssgb.tlli bssgp.ie_type == 0x1f
bssgp.imsi bssgp.ie_type == 0x0d
And so on. As there are further protocols inside BSSGP-frames, it seems that I
can't use their fields as a filter either.
When I need to check any Gb over IP-traces, these identifiers are most useful
for me:
tlli (and tmsi, ptmsi and any equivalent to them; as mobile identity or
allocated p-tmsi or tlli)
P-TMSI signature
imsi
imei (and imeisv)
ipv4_address
cell, RAC, LAC, MNC, MCC (any location information)
Protocols that I need to have those fields as a filter:
BSSGP
LLC
GSM_BSSMAP
There are lots of other fields that I could use and other protocols that I may
need in future, but those are my current need.
