Yes , No IFHO because A2 not Triggered so A5 also not Triggered

Scenario : A2 trhld = -140 db, A5 thrld 1 = -105 db and thrld 2 = -104 db

for my test logs i can see :
Events:

EUTRAN RRC A5 Event: PCell/PSCell becomes worse than ‘threshold1’ and neighbor becomes better than ‘threshold2’
Serving Cell RSRP: (24) -117 dBm
Serving Cell RSRQ: (17) -11.5 dB
Neighbors
Cell ID: 54
RSRP: (70) -71 dBm
RSRQ: (26) -7 dB

but there is no IFHO with this measurements as well.

Can you pls give some clear idea what could be the issue…

Thank you for such a useful article!
Could you please explain is there any time duration between checking Condition#1 and Condition#2 or they happens at the same time?
Thanks

Hi, it was not restricted. Here mostly used scenario in practice was described.

Could you please provide the source of this information and could you explain why event A4 and A5 are restricted to inter-frequency Handover only?
