    Hello All
    this is to start the discussion over the performance issues in GPRS/GSM network.
    can anyone suggest what issues are created when a GPRS is newly integrated in the GSM network, specially in Air interface.

    Hi
    I read your probelm ,in a newly
    integrated gsm network the first which we face is there how much timeslot is given for the GPRS,and how much you given following specify
    1-CDEF
    2-CDED
    3-TRP
    4-BFG
    5-NSEI

    is that correct format or not
    and the timeslot or dedicated or dynamic
    Regards

    Hi Amir
    CDED STANDS FOR DEDICATED GPRS CAPACITY
    CDEF DEFAULT GPRS CAPACITY
    CDED MUST BE SMALLER THAN CDEF

    GIVE ME YOUR MAIL ID I HAVE A SLIDE WHICH WILL GIVE YOU A CLEAR PICTURE ABOUT THIS

    CDED is % of total tsl always used for data and CDEF is % of total tsl that can be dynamically allocated for data but will revert to vioce if needed. A simple example :
    Total tsl avail – 10
    CDED 20% = 2 tsl dedicated to data.
    CDEF 40% = 4 tsl that can be used for data unless need for voice.
    CMAX 100% – I think this is combo of CDED and CDEF = 60% = 6 tsl in this example.
    So CDED cannot be greater then CDEF since you would not be using any tsl dynamically then and have no need for it.
    This is my best understanding of these parameters. If it is wrong in any way please post a detailed explaination.
