Usage Guidelines

A common handover is triggered when the following conditions are met: The RSSI of a candidate link is in the RSSI range of the candidate area, the RSSI difference between the candidate link and current active link is greater than or equal to the RSSI threshold for a Mesh link handover, and the serving time of the current active link is longer than or equal to the link holding time. In actual scenarios, set the proper RSSI threshold for a Mesh link handover. If the RSSI threshold is set too large, the active Mesh link cannot be switched in a timely manner. If the RSSI threshold is set too small, emergency handovers repeatedly occur, degrading vehicle-ground fast link handover performance.

Example

# Set the RSSI threshold for a Mesh link handover to 20 dB in the Mesh handover profile huawei.
