Understanding WiFi Calling
Mobile service providers offer services where you can make voice calls or send and receive text messages from their mobile phones using a WiFi network, without changing the mobile number.
Built-in software applications on smart phones provide seamless authentication of the device when on the Wi-Fi network with the mobile carrier network. When WiFi calling is enabled by the mobile carrier, an IPSec tunnel is established between the phone and the mobile network through which calls are routed.
Due to increasing use of Wi-Fi for device connections, WiFi Calling is seeing high demand by many service providers worldwide, which allows them to differentiate their WiFi access. Though the end-user device and Mobile Packet Core communicate directly over encrypted tunnels, it is important for the Wi-Fi network to detect and prioritize this type of traffic for an optimal application experience.
This feature supports WiFi calling traffic recognition and prioritization above other network traffic, with visibility for Wi-Fi calling stats for the network operator. Following are some benefits of using WiFi calling in Ruckus networks:
- QoS ensures advanced identification rules prioritize voice traffic over data traffic
- Seamless roaming across APs
- Voice call analytics and reporting aid in planning network resource and troubleshooting
- Accurate classification and prioritization of voice calls over WiFi on WLANs
- Enables users to define priorities for voice, video, background and best effort on the WiFi calls generated from a particular carrier phone. For example, you can prioritize your choice of carriers WiFi calls over other WiFi calls.
- Easy to setup and offers the flexibility to add more than one ePDG FQDN/address for a carrier
- WiFi call prioritization when mobile phones roams form one AP to another
