I can’t help you… You said
“absolute power level”.
And I 100% agree with you : the BSC sends absolute power level.
I have no idea what is your problem. You send an order at 28dB to the MS, and the MS is setting its power to 25dB ?
Is that the problem ?
Perhaps the absolute power “coding” you sent to the MS is misinterpreted because the MS is readng it with a different “coding” table than yours. It could happen if the MS is in DCS1800 band and the BSC is using the GSM900 coding.
That’s just a possibility, but I don’t really see anything else. The problem can only be one of misunderstanding :
BSC misunderstands you
or BTS misunderstands BSC
or MS misunderstands BTS
I’m sorry I can’t help more than that.
