hi puru,

you forgot one major information:
which vendor are you working with?

and also:
– are those concentric cells (inner zone / outer zone) or multiband cells (1800 zone and 900 zone) ?
– what is the major cause of the HO? (you should find the split of handover causes in your qos stats)

List of Intracell HO possible causes:

Interferences for non AMR calls
Interferences for AMR calls
AMR FR-HR
AMR HR-FR
TFO
TCH vs PDCH resources management
Inner-Outer Zone
Outer-Inner Zone

And that’s it, for alcatel. Perhaps other vendors propose additional causes.

regards
