Abstract: The present disclosure provides a system and a method for managing a plurality of data networks on a user equipment (UE) (102) by simultaneously utilizing an 3GPP network (104) and a Wi-Fi channel (106) on the UE (102) for data usage by utilizing the 3GPP network by a first UE application and utilizing the Wi-Fi channel by a second UE applications and access traffic steering, switching, and splitting (ATSSS), pushing rulesets into the UE that allows control traffic to a network operator for a desired application based on security, criticality, and priority. Th steering includes packet-level switching and splitting through a multipath transmission control protocol and a flow-based data switching.
