I thought FP was transgered over UDP only, but in general se athe similar questions http://ask.wireshark.org/tags/umts-fp/

See: http://wiki.wireshark.org/FP

More specifically: The FP dissector is mostly functional, but can currently only be invoked while reading Catapult DCT2000 or Tektronix K12 format traces (these contain the additional information needed in order to properly decode the frames). It would be possible, but challenging, to decode the RRC messages describing the configuration of the lower layers, and use this information to infer how each FP frame should be decoded.

It actually works partly if NBAP and RRC signaling is present.

Then we should update the Wiki page ;)

How can we determine if RRC signalling is present? Is it as straightforward as seeing packets labelled as RRC? Or does it require some decoding?
