Thanks & best regards

From someone,

For optimising the Soft Handover (SHO) usually a parameter "Soft Handover (SHO) Overhead" is measured and tuned. This value is easy to measure. The metric, i.e. measured value of "SHO Overhead" is tuned to a (arbitrary) specific target value. This target value is determined based on uniform traffic distributions and provides decent network performance for such cases. The target for the "SHO Overhead" in the tuning is also often set to a value which is acceptable in terms of the allowedcapacity for the backbone network, e.g. Iub links. The importance of the "Soft Handover Overhead" metric is to make sure that the overhead in terms of the number of connections per cell is not excessive.

Soft Handover Overhead is calculated in two ways. 1) Average Active Set Size – Total Traffic / Primary Traffic. 2) Secondary / Total Traffic
Typical Values are like
1.7 (Avg Active Set Size)

or 35% (Secondary / Total )

Hope it helps.

Regards.

we know that SHO Overhead is a ration of resource consumption. This is formular of Nemo
(As_size_1_count + As_size_2_count*2 + As_size_3_count *3)/((As_size_1_count + As_size_2_count + As_size_3_count) -1)*100

Sr, this is formular
((As_size_1_count + As_size_2_count*2 + As_size_3_count *3)/(As_size_1_count + As_size_2_count + As_size_3_count) -1)*100
