Configuring Multimedia Air Interface Optimization

Context

Adjust WMM parameter settings as follows:

Manual adjustment: You can manually adjust EDCA parameter settings and ACK policies for APs and STAs.
Automatic adjustment: After multimedia air interface optimization is enabled, the system automatically adjusts EDCA parameter settings and ACK policies for APs and STAs.

After multimedia air interface optimization is enabled, the system dynamically adjusts EDCA parameter settings and ACK policies based on the number of different types of access users, improving user experience on voice and video applications.

The number of voice or video users is identified based on the user packet density threshold configured using the multimedia-air-optimize threshold command. If the number of voice or video packets sent by a user through the internal statistics queue of a radio with the unit time (1 second) exceeds the threshold, the user is considered a voice or video user.

After the multimedia-air-optimize enable command is executed, the wmm edca-ap and wmm edca-client (SSID profile view) commands do not take effect.

For details about the configuration for manual EDCA parameter adjustment, see Configuring WMM.

Pre-configuration Tasks

Before configuring multimedia air interface optimization, complete the following tasks:

Configure basic WLAN services.

Procedure

Run system-view
The system view is displayed.
Run wlan
The WLAN view is displayed.
Run rrm-profile name profile-name
A radio resource management (RRM) profile is created, and the RRM profile view is displayed.
Run multimedia-air-optimize enable
Multimedia air interface optimization is enabled.

By default, multimedia air interface optimization is disabled.
(Optional) Run multimedia-air-optimize threshold { video video | voice voice } ^*
The user packet density threshold is set for multimedia air interface optimization.

By default, the video user packet density threshold is 100 per second, and the default voice user packet density threshold is 30 per second.
Run quit
Return to the WLAN view.
Bind the RRM profile to a radio profile.
1. Run radio-2g-profile name profile-name or radio-5g-profile name profile-name
  The 2G or 5G radio profile view is displayed.
2. Run rrm-profile profile-name
  The RRM profile is bound to the 2G or 5G radio profile view.
3. Run quit
  Return to the WLAN view.
Bind the radio profile to an AP group or a specific AP. For the detailed procedure, see Binding a Radio Profile.

Verifying the Configuration

Run the display rrm-profile name profile-name command to check configuration of the multimedia air interface optimization function.
