please any one can advice me about the CIO parameter setting , why the default value is 0 , and when I need to change it .
I know that it affect the drop rate , but I need to know under which conditions it will ?

Im not also familiar with this parameter, but as someone hinted to me, CIO is a 3G handover parameter. The higher the CIO,the earlier it will handover to neighbor cell, therefore the lesser the chance of call drop because of handover failure. Im not even 1% sure if my argument is correct. Comments pls.6th September 2013 at 12:18 #69006pixGuest
Definition (copied from doc)
The offset is added to the measured quantity before the UE evaluates whether an event has occurred. Improper use of non-default values may result in instability and unequal cell borders.
By applying a positive offset, the UE sends a MEASUREMENT REPORT message back to the SRNC as if the measured value is offset higher than reality. By applying a negative offset, the UE considers the measured value to be offset lower than reality at event evaluation.
-10 dB (late detection) –> 10 dB (early detection)

Hi, I want to understand, what are the conditions other than Cell Unavailability, for a Cell, that triggers the counter to peg under Category of Drop due to Unmonitored Neighbors.In simple understanding, can anyone share the reasons of drop due to unmonitored neighbors.

Hi, you can change de CIO (Cell Individual Offset) when you want perform HO easier, while greater CIO value is easier the HandOver to target Cell.30th March 2019 at 12:01 #69009AlaaGuest
why I need to add an offset value ?
what is the important of this value ?27th June 2019 at 10:14 #69010Murali AnandGuest
Why CIO is not required for inter rat handover?
