Summary of Vehicle-Ground Fast Link Handover Configuration Tasks

Summary of Vehicle-Ground Fast Link Handover Configuration Tasks

A rail transportation system involves the following scenarios:
  • Scenario 1: Each train travels on a fixed line.
  • Scenario 2: A train may switch between traveling lines.

Both of the scenarios above require the configuration for vehicle-mounted and trackside APs. The differences between the configurations are listed in Table 15-3.

Vehicle-mounted APs support the configuration for scenario 2 from V200R009.

Table 15-3  Vehicle-ground fast link handover configuration tasks

Task

Description

Configuration Difference Between Scenarios 1 and 2

Configure vehicle-mounted APs.

Configuring Mesh Radio Parameters

Configure the same channel and bandwidth for both the vehicle-mounted and trackside APs.

In scenario 1, configure only one working channel for radios on a vehicle-mounted AP.

In scenario 2, configure different working channels for radios on a vehicle-mounted AP, which map working channels of trackside APs on different lines.

Configuring a Security Profile

Configure a security profile and a security policy to improve Mesh security.

In scenario 1, configure only one security profile for a vehicle-mounted AP.

In scenario 2, configure multiple security profiles for a vehicle-mounted AP to map the Mesh networks where trackside APs on different lines reside.

(Optional) Configuring a Mesh Whitelist

Add trackside APs to a Mesh whitelist so that the vehicle-mounted AP can set up Mesh links only with the trackside APs in the whitelist. If the Mesh whitelist is not configured, vehicle-mounted APs can set up Mesh links with all trackside APs.

The Mesh whitelist is not recommended in scenarios 1 and 2.

If a Mesh whitelist is configured:
  • In scenario 1, add all trackside APs on the line to the whitelist.
  • In scenario 2, add all trackside APs on different lines to different whitelists.
Configuring Train-Ground Communication (For Vehicle-Mounted APs in V200R007 or Later)

Configure the vehicle-ground communication mode based on site requirements.

No difference

Configuring a Mesh Profile

Configure Mesh profile parameters to generate a Mesh VAP for setting up links with trackside APs.

In scenario 1, configure only one Mesh profile for a vehicle-mounted AP, set the Mesh ID, and bind the Mesh profile to the security profile.

In scenario 2, configure multiple Mesh profiles for a vehicle-mounted AP, set different Mesh IDs, and bind the Mesh profiles to the security profiles.

Configuring Proxied Ground Devices

Configure proxied ground devices. When a train turns around, data streams sent to the ground network are routed to the vehicle-mounted AP at the front, ensuring normal data transmission.

No difference

Configuring Proxied Vehicle-Mounted Devices

Configure proxied vehicle-mounted devices. When a vehicle-mounted AP connects to a new trackside AP, devices on the ground network can forward data to the vehicle-mounted AP through the new trackside AP.

No difference

Enabling IGMP Snooping on a Vehicle-Mounted AP

Configure uninterrupted multicast services.

No difference

Configure trackside APs.

Adding APs

Add trackside APs to the AC for management.

No difference

Configuring Mesh Radio Parameters

Configure radio parameters for trackside APs.

No difference

Configuring Parameters for an AP's Wired Interface

Configure the wired port of trackside APs to work in root mode, and add the ports to VLANs.

No difference

Configuring a Security Profile

Configure a security profile and a security policy to improve Mesh security.

No difference

Configuring a Mesh Whitelist

Add vehicle-mounted APs to a Mesh whitelist so that the APs can communicate with trackside APs.

In scenario 1, add vehicle-mounted APs only on a train traveling on the current line to the Mesh whitelist for the current line.

In scenario 2, add vehicle-mounted APs on trains traveling on multiple lines to the Mesh whitelist for the current line.

Configuring a Mesh Handover Profile

Bind a Mesh profile to a Mesh handover profile to provide the fast link handover function.

No difference

Configuring a Mesh Role and Mesh Profile

Configure trackside APs as MPPs and a vehicle-mounted AP as MPs, and set Mesh profile parameters.

No difference

Guaranteeing Multicast Data Transmission

Configure uninterrupted multicast services.

No difference
