This is Routines for Radio Access Network Application Part Protocol dissection Based on 3GPP TS 25.413 V3.4.0.
 
Using ethereal for a protocol test, I found a some problem.
 
First problem found in Initial UE, RANAP Procedure.
Initial UE have 6 IEs, CN_Domain Indicator, LAI, SAI, NAS-PDU, Iu Signalling Connection ID and Global RNC_ID.
 
I could not decode Iu Signalling Conntion ID and Global RNC_ID.
 
ethereal only print out 'Malformed Packet'. because IuSigConID Decoding is mal-functioned, and GlobalRNC_ID Decoding is not coded.
 
I try fix routine, and Decode again, But This problem is not solved.
 
Second problem founded in RAB Assignment Request Message.
SDU Format Parameter is not docoded in SDU Parameter ,RAB Parameter, RAB Assignment Request.
 
I try fix the source code. try again. found the problem.
 
problem occured when RAB Subflow Combination bit rate number is over 2. that is 1 is decoded well, and 2 is not  decoded.
 
ethereal only print out 'Malformed Packet',
 
Can you help me?
 
Sincerely,
