Wi-Fi Calling

Certain mobile service providers offer Wi-Fi Calling, allowing built-in software applications on smartphones to initiate an authentication process between the mobile device and the mobile carrier through the Wi-Fi network.

As a result, an IPsec tunnel is established between the phone and the mobile network using Wi-Fi, through which calls, and SMS messages are routed. Although the end-user device and Mobile Packet Core communicate directly over encrypted tunnels, the controller can identify and prioritize Wi-Fi Calling traffic according to the Wi-Fi Calling profiles you create.

Note: There is no need to enable the Wi-Fi Calling feature in the controller for Wi-Fi Calling to function. End-user devices (smartphones) and mobile service providers communicate directly, and form encrypted tunnels using the regular IP service provided by the Wi-Fi network. The access points or controller do not intermediate this communication. However, the RUCKUS controller can detect and prioritize Wi-Fi Calling traffic to ensure an optimal application experience.

In this section:

  1. Creating a Wi-Fi Calling Profile
    You can classify the voice packets in a Wi-Fi call based on the carrier by creating a Wi-Fi calling profile.
  2. Configuring Wi-Fi Calling in a WLAN
    Use the configuration option to create the Wi-Fi policies.
  3. Analyzing Wi-Fi Calling Statistics
    Wi-Fi calls are tunneled to the carrier’s Evolved Packet Data Gateway (EPDG), which eliminates dropped calls when switching from Wi-Fi to LTE and vice versa. Multiple carriers’ EPDGs can be supported on a single WLAN. Wi-Fi Calling coexists seamlessly with RUCKUS CBRS (Citizens Band Radio Service) APs.
