Usage Guidelines

An emergency handover may occur when the radio environment is unstable or a trackside AP fails. To prevent back and forth handovers between trackside APs (ping-pong handovers), you can configure penalty parameters for an emergency handover. The penalty parameters include the penalty period and penalty level. When an emergency handover occurs, the vehicle-mounted AP disconnects the active link from a trackside AP. If the RSSI of the trackside AP falls within the RSSI range of the candidate area before the penalty period expires, the vehicle-mounted AP deducts the penalty level from the RSSI of the trackside AP before making handover calculations based on the handover algorithm.

Example

# Set the penalty period for an emergency handover to 1,000 ms and penalty level to 20 dB in the Mesh handover profile huawei.
