Embodiments include receiving one or more packets of a Wi-Fi calling session via a secure tunnel from a user device, where the user device is connected to a source network via a Wi-Fi access point. Embodiments also include determining whether the Wi-Fi calling session is a threat based, at least in part, on identifying an anomaly of at least one packet of the one or more packets. An action can be taken if the Wi-Fi calling communication is determined to be a threat. More specific embodiments include determining the at least one packet is associated with the Wi-Fi calling session by correlating information in the packet with control plane data of the Wi-Fi calling session. Further embodiments can include intercepting the one or more packets in a second secure tunnel established between an evolved packet data gateway and a service provider network associated with the user device.

A gateway is preconfigured to establish an Internet Protocol (IP) tunnel with a default local mobility anchor on behalf of a mobile node. The gateway receives from the mobile node an Internet access request including a mobile identifier and authorization and authentication protocol information, and sends to the default local mobility anchor an IP tunnel request to establish an IP tunnel. The gateway receives from the default local mobility anchor a tunnel redirect message to redirect the IP tunnel from the default local mobility anchor to a serving local mobility anchor and, responsive to the tunnel redirect message, authenticates the mobile node and establishes an IP tunnel with the serving local mobility anchor through which the mobile node communicates.
