hi:

Mobile communications, 5gc network. /namf-comm/v1/ue-contexts/imsi-******/n1-n2-messages messages.

It belongs to the http/2 protocol and encapsulates the content of different protocols Content-Type: application/json, Content-Type: application/vnd.3gpp.5gnas and Content-Type: application/vnd.3gpp.ngap.

The current highest version of wireshark does not support the decoding of Content-Type: application/vnd.3gpp.5gnas and Content-Type: application/vnd.3gpp.ngap. Is there any good solution?

Can you post the Wireshark version info from the Help -> About Wireshark -> Wireshark dialog?

My Wireshark version is "Version 4.2.0 (v4.2.0-0-g54eedfc63953)." I found similar decoding information on some forums and am trying it. For my problem, the encoding rules need to be found from 3gpp ts29.518 Chapter 6.1.6.4 binary data and need to be decoded manually.

That should be working. Do you see the http2 messages decoded properly?

Yes, I can see that the http2 headers are decoded correctly. In response to my problem, I found some relevant information. I should find the encoding rules from 3gpp ts29.518 Chapter 6.1.6.4 binary data, and need to manually decode it.

Can you open an issue and share a trace?
