Which Event will be trigger?

Suppose the Iur interface is not defined between two RNC, so which event will be trigger before handover between one RNC to another?

If Iur is not defined between the Source RNC and the drift RNC, you will get drops due to IuR..mostly because of missing neighbors between the 2 rnc's.

Only Hard Handover (if the neighbors are declared in DB) . assuming the neighbor cell is on the same frequencey , you will get event 1D (HHO Replace best cell)

1A : add new cell to Active Set (monitored set ==> active set)
1B : remove worst cell from Active Set
1C : replace worst cell in Active Set (monitored set <==> active set)
1D : replace the best cell (this includes intra frequency HHO)

yes, it is the answer ! only hard handover then will get event 1D

in the event of ho during inter-rnc, drops and failure will occur because neighbors between inter-rnc are not defined. I already experienced several incidents between undefined inter-rnc neighbors. (if this is useful, please add reps thanks man)

absolutely, two relation must be created then hard handover applying for mobility
