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?
