fahim,
the multiband cells are using special algorithm to HO the calls in 900/outer to 1800/inner zone.
you should set the RXLEV_DL_ZONE and RXLEV_UL_ZONE, and the ZONE_UL_HYST and zone_DL_HYST…
it’s a bit complicated, i suggest you refer your problem (and how you would like your cells to behave) to your optimization engineer (or alcatel engineers…)
