Good afternoon!
We on a network have a following problem: on Gb
Transaction Type: RADIO-STATUS (BSSGP Transaction) c Radio cause value:Radio contact lost with the MS.
Whether who faced the given problem, if yes as have solved a problem. Who can will prompt where to search, on what interface?
In the relation good rxlev, good rxqual, good neighbors of questions doesn’t arise, since the given reason is present at different honeycombs, during different time frames (loading of the data immediately was thus checked being at most BTS). In a cell exposed gprsMaxNumberPDCHRes = 7 or 14, but RADIO-STATUS (BSSGP Transaction) c Radio cause value:Radio contact lost with the MS is present. Loading Abis – 70 % in a maximum.
PPXU are loaded Prime Time =48 %, Total Time =58 %
Whether Можел to be the reason in adjustments BSC or probably there are no other resources.
p.s. During time contact lost MS, at once produced an outgoing call, MS answers.
It is difficult to understand your text. Are you doing an automatic translation ?
Back to GPRS : the problem comes from radio quality. The quality can be bad for GPRS connection and be good for Voice connection, there is no paradox here.
Check your RC retransmission rate, check your MCS usage, check your TBF Drop rate, their causes.
Check the TCH Establishment failure causes.
