Reply To: High SDCCH Establishment failure rate


According to the KPI document in use:
from the BSS side: message in question is CHANNEL REQUIRED, BTS => BSC.
from the NSS side: an SCCP CONNECTION CONFIRMED message.

is it mentioned that due to the fact that these are under two different protocols, indicator may present values that do not report the end user perception.

the indicator is according to the vendor´s documentation.

the main challenge is to identify possible reasons that justify this bad behaviour and solution to make it better.
