what is the value of sdcch assignment failure rate due to radio problem ?
if Abis or Ater link is over satellite, this might explain the high failure rate : you need to set longer values for several timers (for gsm and gprs).
Can you list the values of the following QoS indicators, per cell :
sdcch drop rate
tch assignment failure rate
tch allocation efficiency (per TRX)
tch drop rate
RACH, PCH, AGCH loads & numbers
SDCCH traffic model (rate of LU, OC, TC, IMSI detach, etc)
SDCCH traffic BH per TRX
TCH traffic BH per TRX
Radio Measurements, per TRX:
– RXLEV DL AVG
– RXLEV UL AVG
– Path Balance Avg
– Timing Advance Avg
(these indicators are at the bottom of the list of indicators in RNO)
The path balance might be the problem… Please list all these values, for one typical day.
