the handovers algorithms are complex, and there could be fewreasons why the ho is not taking place:
– congestion in target cell
– high traffic load in target cell
– neighbour belong to a different band or a different layer
you have checked the inc ho matrix for that particular neighbour, if i understood well ? and the incoming is good. What about the ho in the other way around ?
If the statistics are showing HO Req and HO Succ, then I would strongly believe that the HO is not taking place for your particular MS, due to one of the reasons above.
How many HO Succ and HO Req are measured, between these 2 cells, in both directions, for one full day ?
