    There are just names of parameters with their values. There is no explanation in tools collecting logs which I am using.

    Oh!!!
    Pawel,many of the parameters are self explainatory,like es_ind,rf_power_cap etc etc.Name only those which bothers you the most

    Hi,..

    Can anyone tell in which practical scenario classmark change comes under the picture.

    I know what is the use of classmark. But why classmark change procedure required while location update or CM procedure is ongoing.

    hi,

    The MS sends this message to the network, to list all its capabilities. The network is then aware of what the MS can or cannot do.

    Hi Mr.PIX,

    I know what is classmark. But sometimes classmark change is come under the picture, when at all MS change its capabilities (like Band info, addition of power amplification). How come it changes band info and add the power amplification. That is what i thought to ask. Can you any practical scenario, why it is doing addition of power amplification

    When at all it needs to change the classmark. Why it needs to change Band info and addition of power amplification

    Hi,

    I don’t know. It’s part of the standard procedure, you’d have to check 3GPP on that one…

    where you seen this parameters?
    As i am using the TEMS release 5,
    the information of repeated SACCH(ACCH capability) is not indicated there.
    So, can u suggest the tool, where i see these parameters.

    I understand that to prevent attacks on A5/3, networks have started rejecting classmark change requests (sent from a fake MS) to A5/1. Would like to understand if this is true (at least on some parts of the world) and whether this is a directive to be fulfilled by all operators by a specific date.
