Configure Mobility Parameter

In the left navigation column, select “NR Setting > Mobility Parameter” to enter the
mobility parameter configuration page.
The Mobility Parameter menu pertains to how roaming UE sessions are handled
between different gNBs in the same service area. When a UE is actively connected to an
gNB is referred to as the serving gNB or cell. The other gNBs in the area are referred to
as either neighbor or target gNBs or cells.
The process of a device moving from cell to cell and changing over from its serving gNB
to a neighbor (target) gNB is called handoff or handover. The UE exchange information
with its serving gNB to perform cell selection and reselection based on parameters which
you will set for each gNB.
7.7.1 A1 Event Threshold
The A1 event is triggered when the serving cell’s Reference Signal Received Power
(RSRP) is better than the A1 threshold. The A1 event can be used to turn off certain
inter-cell measurements.
The conditions for entering A1 event are shown in formula 4.1, and the conditions for
leaving A1 event are shown in formula 4.2.
