In a mobile device operative in a packet switched wireless network, the control logic for handling the PS connection resides inside the modem part of the device when dual-stack operation is required (e.g., PDN connections having PDN types IPv4 and IPv6). This effectively hides how dual-stack IPv4v6 connectivity is implemented towards the relevant 3GPP network. Further, the modem always only uses one and only one network interface, as seen from the IP stack, when it operates in dual-stack mode, regardless of how the underlying PDN connection(s) are set up.
