Radio Resource Control RRC

History

The Radio Resource Control (RRC) protocol for the UE-UTRAN radio interface.

Protocol dependencies

Example traffic

XXX - Add example decoded traffic for this protocol here (as plain text or Wireshark screenshot).

Wireshark

The RRC dissector is partially functional. Currently, there are no links to the main dissector due to a lack of traces with RRC; however, the dissector should be able to dissect the entire protocol.

Preference Settings

(XXX add links to preference settings affecting how PROTO is dissected).

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.

• SampleCaptures/PROTO.pcap

Display Filter

A complete list of PROTO display filter fields can be found in the display filter reference

Show only the rrc based traffic:

 rrc

Capture Filter

You cannot directly filter PROTO protocols while capturing. However, if you know the TCP port used (see above), you can filter on that one.

Capture only the PROTO traffic over the default port (80):

 tcp port 80
