Hi

Can anyone explain what rrcConnectionSetupComplete-r3-add-ext bitstring means:

- <UL-DCCH-Message>

- <message>

This is 3GPP, check 25.331...

Please see the asn.1 definition from 25.331:
rrcConnectionSetupComplete-r3-add-ext BIT STRING
(CONTAINING RRCConnectionSetupComplete-r3-add-ext-IEs) OPTIONAL

RRCConnectionSetupComplete-r3-add-ext-IEs ::= SEQUENCE {
rrcConnectionSetupComplete-v650ext RRCConnectionSetupComplete-v650ext-IEs OPTIONAL,
v680NonCriticalExtensions SEQUENCE {
rrcConnectionSetupComplete-v680ext RRCConnectionSetupComplete-v680ext-IEs,
v7e0NonCriticalExtensions SEQUENCE {
rrcConnectionSetupComplete-v7e0ext RRCConnectionSetupComplete-v7e0ext-IEs,
v7f0NonCriticalExtensions SEQUENCE {
rrcConnectionSetupComplete-v7f0ext
RRCConnectionSetupComplete-v7f0ext-IEs,
nonCriticalExtensions SEQUENCE {} OPTIONAL
} OPTIONAL
} OPTIONAL
} OPTIONAL
}

If you look into the detail, all IEs are related to the UE radio access capabilities.

Thanks, I know it. But I am interested in content of bit string

<rrcConnectionSetupComplete-r3-add-ext>101000100000100000000110000110011000000000000011</rrcConnectionSetupComplete-r3-add-ext>

What information does this bit string convey?

All the information in the RRC complete message is related to different UE's capabality...

Hi,

First of all, your decoder doesn't work. Otherwise, this bit string would have been decoded into meaningful ASN.1 sequence.

Hi.

I did not find information about rrcConnectionSetupComplete-r3-add-ext in 25.331 so I have this question.

Thanks.

you should look at "RRCConnectionSetupComplete-r3-add-ext-IEs" to understand the contents of "rrcConnectionSetupComplete-r3-add-ext". My understanding is that your decoded doesnt understand "RRCConnectionSetupComplete-r3-add-ext-IEs".

If you have the message in hex you can copy paste here..

3GCellPro - UMTS Protocols Decoder (http://www.3gcellpro-tocols.com/)

and get it decoded. Hopefully their decode is more up to date than your protocol analyser..
