Hi! I recently wrote a wireshark dissector for the CBSP protocol, which is a 3GPP standard for the interface between the Cell Broadcast Centre and the BSC. It's specified in 3GPP TS 48.049 in case you're curious. The dissector can be found at https://code.wireshark.org/review/#/c/29745/ However, I couldn't find any protocol traces to verify the dissector against. So if you happen to have done any work on cell broadcast in 2G network and have a CBSP trace around (or can generate one): Please send it to me, thanks! If I ever find the time, I'd love to add CBSP support to OsmoBSC, and even to go one step further and write a minimal CBC itself. Contributions are of course always welcome, in case there are other interested folks.
