Hi Anders,
Please see the answers from our developers regarding the issue:
============
The wireshark decode the rrc container to HandoverToUTRANCommand, it is error.
We use radiobearerreconfiguration as the ho message for ue in intra rat ho, not
HandoverToUTRANCommand
============
But I still stay with a problem to decode the HO flow
Please advise,
regards,
Slawa
