hi alonewolves,

when failure is 100%, the problem always come from a faulty HW.

Now, i don’t know Nokia systems, but you might want to check the PCU (packet control unit) congestion or processor overload. Under extreme stress, I assume defense mechanisms are activated (tbf assign reject?). Also, maybe it’s your BTS processing unit that’s overloaded.

I have no other suggestions… check interfaces congestions as well (ater, abis, Gb)

I don’t think the core network (SGSN) could be the problem here.

Again, i would say that’s either a BTS or a PCU HW problem.

Regards
