    A number of IE related to HSDPA will be present in the RRC Connection Setup. The easiest to look for will be an H-RNTI present at the beginning of the message.

    Hi,


    It is simple to benchmark feature affect via DT. Basically perform HSDPA call set up once without feature and once with feature activated and then evaluate call set up time . For sure with feature activated it will be meaningfully lesser.

    There is another way also which normally is not required to be that much detailed.


    Cheers

    Hi,

    Yes it is possible , You need to refer to RRC Conection setup message in L3 in TEMS then open it and look at "DL-TransportChannelType-r5" and "UL-TransportChannelType", "ul-TrChType" elements . In case feature is OFF it takes "dch", "dch" values in both UL and DL direction and when it is ON it takes "hsdsch", "e-dch" values in DL direction. THere are some more info in L3 to distinguish the functionality but the explained one will be enough for your purpose. Hope it helps you



    Cheers
