During SHO a UE has more than one brach and the UE is dropped.

How is it possible this?

Plesease help me.

there are some reason, neighbor list, pilot pollution, resource congestion...
If you provide the logfiles, i think we can pass over.

Hi ,
as first assumption I uspect a missing neighbour, just check the active set measuerement data cell/UE and the monitored/detected cellslist .if all OK
have you check the messages prior the drop in the protocols stack?
Anyway the logfile will help us to help u!

Best regards

You need to check whether the UE is sending MEASUREMENT REPORTS prior to the release for cells that are not being added to the active set. All RAN vendors have a parameter that controls the triggering of a release if a cell that cannot be added to the active set exceeds a particular threshold.

Of course it could be something unrelated to the above, but it is a good place to start.
