BreezeCOMPACT Full Configuration via CLI
To set the HO triggers, you define the measurement type and thresholds for the A5 triggers
using the following commands:
 set cell handover-triggers measurement-type <RSRP or RSRQ>
Sets the way how the measurement will be prformed (based on RSRP or RSRQ)
 set cell handover-triggers a5-threshold1-rsrp <Defines the RSRP level for
threshold 1>
Specifies the Threshold 1 value used in an E-UTRA measurement-report triggering
condition for the A5 (dBm) RSRP event.
 set cell handover-triggers a5-threshold1-rsrq<Defines the RSRQ level for
threshold 1>
Specifies the Threshold 1 value used in an E-UTRA measurement-report triggering
condition for the A5 (dB) RSRQ event.
 set cell handover-triggers a5-threshold2-rsrp <Defines the RSRP level for
threshold 2>
Specifies the Threshold 2 value used in an E-UTRA measurement-report triggering
condition for the A5 (dBm) RSRP event.
In order to show the current handover trigers related parameters in the ENB perform the
following command from CLI BreezeCompact% prompt:
 show cell handover-triggers
As a result the output should look like that :
measurement-type RSRP; a5-threshold1-rsrp -140;
a5-threshold2-rsrp -140;
a5-threshold1-rsrq -20;
a5-threshold2-rsrq -20;
An A3 HO event basic form the UE sends an A3 measurement report when a non-serving
cell RSRP becomes better than the serving cell RSRP by a margin defined by an A3 offset
parameter. (A3-OFFSET parameter units is 0.5db)
In other words, when ∆RSRP > A3 offset,
where ∆RSRP = RSRPneigh − RSRPserv.
Figure below shows an example of the A3 reporting event.
