interesting behaviour !
i’ll try to dig further, but I can’t promise anything soon…
did you try other settings of QSearch_C ? The idea would be to see whether the number of HO REQ when QS_C=15 is similar to the number of HO REQ with a little more “favorable” QS_C.
(for example, measure 3G only when 2G signal is extremely good… let’s assume such behaviour is defined by QS_C=14, just for the sake of my demonstration. I actually don’t know the coding of the QS_C and I’m too lazy to go find it out ! But the idea is to take a very restrictive setting)
I would expect the number of HO Req to be much lower at 15 than at 14.
And if that is the case, then I would say that some MS are not obeying the value “15” !
On the other hand, if the number of HO Req is similar, then I would suspect a faulty BSS behaviour.
