Are these messages send using the framing format mentioned in
http://wiki.wireshark.org/MAC-LTE ?
If so, then you need only turn on the MAC-LTE protocol preference 'Try
heuristic LTE-MAC over UDP framing'.

If not, then you'll need to create your own dissector for your format,
parse out the required information and call set_mac_lte_proto_data() (see
http://anonsvn.wireshark.org/wireshark/trunk/epan/dissectors/packet-mac-lte.h)
and call the mac-lte dissector for the PDU itself.

There are currently MAC and RLC statistics, but not RRC...  You should
automatically get those statistics, although for RLC you should check your
MAC-LTE preference settings to ensure that the MAC SDUs are called with
correct RLC format (i.e. mode, sequence number length).

Good luck,
Martin
