increase sdcch capacity until there is no more SDCCH congestion.
TCH congestion is less critical for the network, and can be reduced by other means (HR, off-load to neighbours/micros, drirected retry, etc)
HR is already activated and I think directed retry also. Can I really apply it to a scenario like this : Sd cong =27%, TC cong= 27% or Sd cong=11% and TC cong=26%.
Can you explain me why SD cong is more critical than TC cong?
Thanks again for your quick response.
