    I increased CDED & CDEF on a site and my throughput has gone up a little as expected. I also noticed gprs_ter_upgrd_req counter has dropped off from an average of 1100 requests daily to 300. Is this to be expected? Is this all due to the increase in CDED and is this all good?

    Hello,

    What is definition of CDED?
    Perhaps I can relate to our parameters.

    CDED is number of tch channels dedicated to data

    CDED is actually a percentage of avalable channels dedicated to data

    the gprs_ter_upgrd_req counter has decreased probably because less MS are needing additional PDCH : they are already fully served.

    If there is not enough PDCH in the cell (= if CDED is too small) then the MS will keep trying to get more PDCH, therefore more gprs_ter_upgrd_req are counted.

    So this appears to be a normal result and should not be a concern as long as the site is carrying the same (or larger)volume of data traffic as it did prior to my changes, correct? Does the reduced number of requests help the site performance in any other way not related to data, possibly reduce SDCCH signaling?.

    No, it just increases the qos offered to the subscriber. SDCCH are never used during a GPRS data call.

    Perhaps it unloads the GPU as well?

    Hi,
    Increasing CDED, which is % from total BTS TCH resource, you reserve PCU resource and radio resource as well. That’s critical for high loaded cells as dedicated TCH can not be used for speech. Increasing CDEF you reserve resource only in PCU and territory upgrade become possible only if radio resource is available. What is the priority, voice or data?

    Operators give more priority to voice : it brings more money than data.

    Of course Pix! That’s why CDEF is better parameter to play with
