Hi Sabyasachi,

Hi Anders,
Thanks for the response. I am using the message structure of TS 36.413 v13.3.0 and wireshark development version Version 2.3.0-2658-gfe285c6 (v2.3.0rc0-2658-gfe285c6). I do not know the process of filling a ticket for wireshark. Attaching the trace here so that you guys can help.Inline image 1


Wireshark tries to decode the S1-Message element as a UE Initial Message PDU, and not as a S1AP message PDU. It means that the decoding is shifted by a few bits, leading to a wrong decoding. I'm gonna fix this.

Hi,

The S1AP dissector in trunk is based on TS 36.413 V13.5.0 (2016-12) so I guess it should decode the message.

The best is to raise a bug attaching a trace with the RerouteNASRequest message and describe what is not dissected correctly.

Regards

Anders

Subject: [Wireshark-users] R13 S1AP message "Reroute NAS Request" is not decoding completely using 2.3.0

 

Hi,

R13 baseline S1AP message "RerouteNASRequest" is not decoding completely using 2.3.0. Can anyone suggest how to proceed on this or is there any plan supporting this.
