urgent-handover low-rate

urgent-handover low-rate

Function

The urgent-handover low-rate command sets the minimum rate threshold for an emergency handover and the minimum rate holding time.

The undo urgent-handover low-rate command restores the minimum rate threshold for an emergency handover and minimum rate holding time to default values.

By default, the minimum rate threshold for an emergency handover is 10 Mbit/s and the minimum rate holding time is 2,000 ms.

Format

urgent-handover low-rate threshold rate-value period time

Parameters

Parameter

Description

Value

threshold rate-value

Specifies the minimum rate threshold for an emergency handover.

The value is an integer that ranges from 1 to 1300, in Mbit/s. The default value is 10.

period time

Specifies the minimum rate holding time.

The value is an integer that ranges from 0 to 10,000, in milliseconds. The default value is 2,000.

Usage Guidelines

In certain scenarios (for example, when fast frequency offset occurs), a link has a high RSSI but a very low rate. If a link handover is not implemented in these scenarios, vehicle-ground communications will be affected. If the link rate has fallen below the minimum rate threshold and stayed in this low-speed state longer than the minimum rate holding time, the vehicle-mounted AP implements an emergency handover to switch the active link.

rate-value refers to the packet transmission rate on the air interface. In actual situations, the rate depends on the radio type, channel bandwidth, GI mode, and spatial streams. For rates supported by different protocol standards, see the corresponding IEEE 802.11 protocol document. Set a proper minimum rate threshold according to user requirements.

Example

# Set the minimum rate threshold for an emergency handover to 20 Mbit/s and the minimum rate holding time to 1,000 ms in the Mesh handover profile huawei.
