Does the MS sends the HO ACCESS, right after the reception of the HO COMMAND ?
The HO FAIL message is in UL, right ? (I forgot)
How many times did this situation occur ? Only once ?
Now, in RNO/NPO : can you check the indicators in “Adjacency” / MATRIX / BASIC (it is the type 180, I’m sure you know)
How many HO Requests & Allocated & Success from this serving cell to each of the top 3 neighbours (in the list you gave)
In the serving cell (Cell Indicator), what is the rate of Outgoing HO Failure Rate ?
I assume you are using ALU ? (And are you one of my trainees I saw few weeks ago ?)
