The F1AP dissector should already handle UL CCCH messages. For DCCH messages, what you have is NR PDCP PDUs and not RRC messages. Moreover they are likely ciphered, that's why I did not add this code. I should probably make the call to the PDCP dissector optional (based on a preference) for the rare cases where ciphering is unused. I should also add DL CCCH dissection. A capture file would be welcome to test the code.
