>>> RETAINABILITY ANALYSIS

1. Drop speech due to soft handover actions

It is dropped Speech calls due to Soft Handover action, which are network initiated call releases due to inability to include a non-valid or

valid cell in the active set. This means that missing neighbour drops due to releaseConnOffset exceeding are included. In general every

cause that does not allow executing a SHO is triggering the counter at numerator

2. Drop speech due to missing neighbor

It is dropped Speech call due to unknown measured cell (missing neighbor relation).

3. Drop speech due to UL Synchronization lost

It is dropped Speech call due to UL Synchronization Lost. It has to be noted that the counter at numerator is only pegged as a UL synch

drop if dchRcLostT (default 5s) expires.
