Multirab Drops in NSN

[rumy]

Hi friends,

We are facing an inssue with MultiRab drops with good RF condtions, in NSN network.
MultiRab combination we are using is CS 12.2 + PS (HSDPA or R99), SwissQual logs with Actix Analyzer.

The strange issue is that on Drop events UE sends CellUpdate with "RLC unrecoverable error" message.
All drop events analysed so far are recorded in FACH state with the previous state been DCH.

Do you have similar experience or any hints on this issue?

Regards!

Hi, yes, we also are experiencing the same. For now no clue what is causing it and how to solve it.
BTW, you are running RU30 or RU40? Also your WBTS SW is 6th or 7th series?
