Hi experts

I’m looking for a decoder for some ASN.1 files coming from a P-GW. I have tried several online tools without success.
It seems you need to know the specific format (fields) into the files. EPS Vendor is Ericsson this case.
I don’t know if they can be converted to pcap for instance to be analyzed with wireshark.
Any suggestion?
thanks in advance.

Hi, @Guillermo_Gomez, ASN.1 should be avaiable in ELEX. But that is require some coding skills.

Checkout PyCrate - It’s a Python library for working with ASN1 and has precompiled decoders for the 3GPP CDR spec, to allow you to take your ASN1 formatted CDRs and turn it into whatever formats you like (CSV, JSON, Excel, etc)
