I have question about reducing TRX from a cell, when asking for reduce TRX for a cell they will software blocking TRX but still ohysical exist in the cell and also in hopping list what will happen???
my network use BBH and what I want is that if the removed frequency for raleted TRX remain in the hopping list I think system will try to allocate this frequency to MS and when there is no dedicated TRX for this frequency is cause performance bad isn’t ????????
ok, so for your problem, i don’t think hopping is the issue. actually, i would suspect two possibilities :
1/ one trx is faulty, but the wrong TRX was locked –> the faulty trx carries more traffic, therefore, there is more call drops, etc.
2/ the faulty trx is locked, indeed, so the other trx’s are going to carry more traffic. It is a possibility that another trx is also faulty, so by locking one TRX, you actually reveal another faulty trx.
that sounds more probable than a wrong hopping management, but who knows…
Which vendor? if ericsson check the counters CNRELCONG and TNRELCONG, are they increased,if yes, this mean that you needed this TRX, and you shouldn’t lock it. Unless you are ready with cell load sharing strategy. on the other hand, in BBH number of frequencies = number of TRXs, and when you lock a TRX, then you are locking the Frequency you assigned to it, this means hoping will not include this frequency.
