VS.HHO.InterFreq.Drop.RNC

VS.HHO.InterFreq.Succ.RNC

This measurement item provides the number of successful inter-frequency hard handovers initiated by the RNC.

The measurement is triggered at point C, as shown in the figure. When the RNC receives a PHYSICAL CHANNEL RECONFIGURATION COMPLETE message, or a TRANSPORT CHANNEL RECONFIGURATION COMPLETE message, or a RADIO BEARER RECONFIGURATION COMPLETE message from a UE during inter-frequency hard handover, the measurement of this item shall be triggered.

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. After it receives a RADIO LIN SETUP RESPONSE message, the RNC sends a PHYSICAL CHANNEL RECONFIGURATION message, or a TRANSPORT CHANNEL RECONFIGURATION message, or a RADIO BEARER RECONFIGURATION message to the UE. At this moment, the measurement of this item shall be triggered.

VS.HHO.InterFreq.Drop.RNC

This measurement item provides the number of call drops due to inter-frequency hard handover failure in the RNC.

During inter-frequency hard handover, the RNC sends a PHYSICAL CHANNEL RECONFIGURATION message, TRANSPORT CHANNEL RECONFIGURATION message, or RADIO BEARER RECONFIGURATION message to the UE and starts a timer to wait for the response from the UE. 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.
