Hi All, I have the below RRC_MEASUREMENT_REPORT Trace sent by UE to RNC.=> this is one packet only . how can I read the values of the three Scrambling codes, and the three RSCPs... using tshark

Hi all I found the solution to this : it will be in the below format : 1,1,1,1,1,1 is the values of the sub items in the same message

tshark -r export_ETHERNET.pcap -T fields -e ip.src -e ip.dst -e ranap.ProtocolIE_Field_element 10.231.35.67 10.235.214.29 1,1,1,1,1,1 10.235.214.29 10.231.35.111

Hi,

tshark cannot read this proprietary log format, so you are out of luck.

Best regards, Pascal.

You didn't read my question well ! tshark does read pcap files, and not this log above. My question is : how can tshark read the pcap trace file and extract the measuredResults fields .

etarira ( Apr 10 '0 )

Well, nowhere in your question it was clear that you had a pcap that would match this proprietary log. If you expect to get some help, it would be a good idea to share the pcap rather than this non Wirehark based decoding. Help us help you.

Pascal Quantin ( Apr 10 '0 )

Fine. That is the problem : I was trying to convert this text trace to pcap trace using text2pcap but it is not giving me any output .

To be more precise , my goal is to read these parameters from measurement report : - OFF - tm - Scrambling code for every neighboring cell. In this case, the returned result should be an array or a list instead of a single value !! This is the trick ! How can i do that.
