If network capability IE in attach request indicate that all the UMTS security functions are not support, can we comfirm that this UE is not support UMTS?
In other words, if UE support UMTS, is it possible that UE set all UMTS security not support in network capability IE when attach request?
Note: UMTS security is include integrity (UIA0~UIA7) and encryption(UEA0~UEA7)
and another question is that is it possible support encryption function but not support any integrity function?
