Anyone experienced congestion with NSN Node_B?
Recently I had a problem with a configuration FSMB+FSMD with a 88% of maximum channel element usage. The problem was presented as a huge increase of RRC setup failures due to cell reselection, admission control and bts / frozen bts. The total RRC attempts (CS+PS) were 10,000 per hour in 3 sectors.
After upgrading hardware FSMD+FSMD, problems dissapeared. THe fact is that only statistics problems appeared, but not any alarm
So, anyone knows the real capacity of a NSN node B? I only have the input of channel element handling, not more
