Hi List, I have been capturing and decoding some live traffic on a GSM network, and find a problem in decoding of GSM MAP operations.
The GSM MAP dissector is currently based on 3GPP TS 29.002 v7.5.0. This leads to incorrect decoding of packets which are working on lower MAP versions. For example, a MAP v2 ShortMsgMT-Relay gets decoded as MAP v3 ShortMsgMO-Relay (because the opcodes are same). This leads to all kinds of warnings, and sometimes incorrect decoding. I don't suppose there is a (simple) way around this, is there? I guess a complex (and resource hungry) method would be for the TCAP dissector to follow dialogs and then pass the application context information to the MAP dissector for MAP to interpret the operation based on the application context in addition to the op-code. I am sorry if this has already been discussed, I searched the archives, but could not find anything relevant... perhaps I didn't use the correct search string. Thanks, Abhik. _______________________________________________ Wireshark-dev mailing list [email protected] http://www.wireshark.org/mailman/listinfo/wireshark-dev
