Configuring a Mesh Handover Profile

Configuring a Mesh Handover Profile


A Mesh profile must have a Mesh handover profile referenced to provide the fast link handover function.


A Mesh handover profile and the FWA mode of a Mesh profile are mutually exclusive and cannot be configured together.


  1. Run:


    The system view is displayed.

  2. Run:


    The WLAN view is displayed.

  3. Run:

    mesh-handover-profile name profile-name

    A Mesh handover profile is created, and the Mesh handover profile view is displayed.

    By default, the system provides the Mesh handover profile default.

  4. Run:

    location-based-algorithm enable

    The location-based enhanced link handover algorithm is enabled.

    By default, the location-based enhanced link handover algorithm is disabled.


    After the location-based enhanced link handover algorithm is enabled, the vehicle-mounted AP will switch the active link to the nearest trackside AP that meets handover requirements.

    In vehicle-ground communication scenarios, signals of a trackside AP distant from a train may be temporarily better than the trackside AP near the train due to radio environment changes. If an active link handover occurs at this time, the active link may be incorrectly switched to the distant trackside AP. To prevent incorrect handovers and improve vehicle-ground communication quality, you can use the location-based enhanced link handover algorithm. This algorithm requires that trackside APs be named in ascending or descending order of sequence numbers.

    Trackside APs should be named in head-name_sequence-number format. head-name describes track line information and can be different for trackside APs on the same track. It is recommended that you set the same head-name for APs on a track to differentiate tracks. sequence-number of APs along a track must be in descending or ascending order. The sequence numbers of trackside APs can be set with unequal steps. head-name and sequence-number are separated using an underline (_), for example, L1_001, L1_002, L1_005, L1_010.
