Frame Protocol (FP)
The Frame Protocol is the user plane protocol used in UTRAN IuB and IuR interfaces. It is described in 3GPP TS 25.427 (Dedicated transport channels) and 3GPP TS 25.435 (Common transport channels)
These transport channel formats are described in R99, R4, R5, R6 and R7 releases of the above documents.
- FP can be transported over AAL2, AAL0 or ["UDP"]
XXX - Add example decoded traffic for this protocol here (as plain text or Wireshark screenshot).
The FP dissector is mostly functional, but can only be invoked at the moment while reading ["DCT2000"] format traces (these contain additional information needed in order to properly decode the frames).
There are currently no preference settings.
Example capture file
XXX - Add a simple example capture file to the SampleCaptures page and link from here (see below). Keep this file short, it's also a good idea to gzip it to make it even smaller, as Wireshark can open gzipped files automatically.
A complete list of FP display filter fields can be found in the [http://www.wireshark.org/docs/dfref/f/fp.html display filter reference]
Show only the FP based traffic:
Because FP traces can only currently be read from existing trace files, there is no way to filter for FP frames while capturing.
