� VS.SHO.AS.4

� Mean Number of UEs with Five RLs

� VS.SHO.AS.5

� Mean Number of UEs with Six RLs

� VS.SHO.AS.6

� This is because we usually set the maximum cell in an active set as 3.

� These measurement items provide the mean number of UEs with different RLs.

� The RNC periodically takes a sample from the number of UEs with different RLs. At the end of the measurement period, the RNC divides the accumulated number by the

number of samples to obtain the average number of UEs with different RLs in the measurement period.

� VS.HHO.InterFreq.Att.RNC

� This measurement item provides the number of inter-frequency hard handover requests initiated by the RNC.

� The measurement is triggered at point B, as shown in the figure. To initiate an inter-frequency hard handover procedure, the RNC first sends a RADIO LINK SETUP REQUEST message to the NodeB.

If the UE returns a PHYSICAL CHANNEL RECONFIGURATION FAILURE message, or a TRANSPORT CHANNEL RECONFIGURATION FAILURE message, or a RADIO BEARER RECONFIGURATION FAILURE message, it indicates that the hard handover fails. If the RNC cannot maintain the call connected before the hard handover, it initiates an RRC connection release procedure, which results in call drops. At this moment, the measurement of this item shall be triggered.
