5G Reselection Analysis Dashboard

Real-time evaluation of idle-mode reselection logic for RF and RAN troubleshooting.

Analysis Workflow

Evaluate serving and candidate cells with a clearer decision flow

Use the measured values, thresholds, and priorities to understand whether the UE can search, compare, and finally reselect the target cell under idle-mode logic.

What this dashboard checks

The tool focuses on reselection decisions using the values you enter. It compares Srxlev, evaluates search conditions, and then applies the priority branch to reach a final result.

Signal Criteria Srxlev = Qrxlevmeas - Qrxlevmin
Decision Inputs Search gates, serving threshold, and priority relation between source and target.
Serving Cell Evaluate Qrxlevmeas, Qrxlevmin, Srxlev, and serving priority.
Search Gates Validate INTER and INTRA search conditions before reselection.
Decision Logic Compare equal, lower, and higher-priority reselection branches.

Reselection Storyboard

Move the inputs and watch how the UE interprets serving quality, opens search, and either stays camped on the source cell or camps on the target cell.

Waiting for values
Serving Cell P7 | Srxlev 29.0
Camped on Source
Target Cell P7 | Srxlev 29.0
The UE starts camped on the serving cell. It only moves when the search conditions and the active priority branch allow reselection.
Serving Srxlev Qrxlevmeas -95 dBm
29.0 dB
This is the current camping quality margin of the source cell.
Target Srxlev Qrxlevmeas -95 dBm
29.0 dB
This is the candidate quality margin the UE compares before it can reselect.
Step by Step

Why the UE stays or moves

Each block below explains the active branch of the logic in plain language, so the result is easier to teach and troubleshoot.

01 Serving

Serving cell quality

The source cell Srxlev is compared against the low-priority threshold.

03 Priority

Priority branch

The comparison path changes depending on whether the target has equal, lower, or higher priority.

04 Decision

Final camping action

The final decision combines the measurements, gate status, and branch rule.
