UMTS RRC Decode

[Alphab]

Hi,

I want to share the UMTS RRC Decode program for Cygwin environment.

You can use it for Windows as well with the cygwin1.dll in the same folder
with the progname.exe executable ...

it uses a .dat file which is the binary content of the RRC dump ...

Usage :

progname -h

progname -p list

you can find the .asn content as well ...

no password, enjoy ...

if you like thanks and add rep ...

unfortunately it runs in the command mode ...

and you have to form the .dat hex dump of the RRC message ...

you have to select the pdu type as well ...

progname -p list : lists the available PDU types ...

Hi, thanks!

Is this Open Source ASN.1 Compiler: asn1c 0.9.22 ?

Have you updated rrc.asn1 definitions, or it is R7 RRC.asn1 as distributed with
asn1c?

great tool, very fast, we use it a lot for GPEH parsing.
Unfortunatelly, asn1c does not work with byte-alligned PER, so NBAP/RANAP/RNSAP
can not be parsed: for those we use wireshark.

It is great to have command line parser, suitable for scripting.
When doing GPEH etc, we just get anything automatically parsed and posprocessed.
I do not see any advantage in E/// approach: Gui to start, GUI to check, GUI to parse...
Far too much time waiting for job to be done.
When I need files, I want them NOW, not after half and hour of clicking.

yes open source asn1c as you mentioned ...

i didnt use the distributed asn, instead i captured from the etsi document ...

this i compiled long time ago, and i really dont remember the release version ..

are you sure alligned PER is not possible with asn1c ?

let me check it also ...

[Alphab]

you are totally right : aligned PER is not supported yet

[s52d]

you are totally right : aligned PER is not supported yet

Author has other priorities, well away from ASN.1, so it probably never be.

Hi
