      Hello,


If you want to capture frames on a GSM network, you should have a look to
the GSM wiki, and to the CaptureSetup/SS7 wiki.

I think the easiest way is to connect a monitoring equipment for E1 (or
board) on the A interface. So you will have all the messages exchanged
between the MS and the Network.
If you are using a board for the capture on the Wireshark PC, you can have
a realtime monitoring.
If you are using a Telco monitoring equippment, you will probably have to
save the capture in a file, and to do the analysis later on our wireshark
station.

The GSM dissectors in wireshark are compliant to the 3GPP, so should be
compliant will all the vendors.

Hello list members,

I noticed the GSM features in Wireshark, but I'm a bit confused about using
WireShark to sniffer traffic in our GSM network, how can I connect to the
network?

1- Plug the wiresharked PC into the related interface (A=fiber, Abis=E1's,
...) How to realise it?
2-Attach an Fiber & E1 cards to the pc (does it exists?)
3-Use OMC service ports (only O&M data)
4- ...

Mainly I need a way to extract some user related parameters from those
interfaces, such as IMSI, IMEI, NMR and TA for positioning. Is it
applicable  as real time or I must dump a file and  do analysis later by
wireshark.

Does Wireshark GSM analysis compatible with all vendors, especially
Ericsson?

Thanks in advance ...
