When connected to a cellular (e.g., 5G) network a device can receive/transmit Internet Protocol (IP) traffic via the packet data protocol (PDP). When connected to a Wi-Fi network a device can receive/transmit IP traffic via the Institute of Electrical and Electronics Engineers (IEEE) 802.11 protocol. This proposal provides for combining the capabilities of both cellular and Wi-Fi via a Wireless Link Aggregation (WLA) technique that allows for seamless roaming, no IP address change and no gateway change for a mobile device that is switched between access links, and enhanced experiences for users.
