The observed event include: cell reselection, handover, handover (intracell), handover failure and intracell handover failure.

Information Element of the most influential for the handover and the handover failure is received power, whereas for two other events the most influential is the received bit error.

There is only once handover intracell failure happened which may be caused by full traffic in candidate channel, but no cell reselection failure is found because this event doesn’t need traffic channel but only signaling channel.
