1. A wireless transmit/receive unit (WTRU), the WTRU in communication with a wireless communication network, the WTRU comprising:

  • a processor, configured, at least in part, to;

    create a first virtual network stack (VNS);

    obtain a first internet protocol (IP) address from a first node;

    associate the first IP address with the first VNS;

    associate a first interface with the first VNS;

    initiate a first application on the first VNS;

    initiate a first IP flow between the WTRU and the first node via a first connection corresponding to the first VNS, the first IP flow corresponding to the first application;

    initiate a handover to a second node of the wireless communication network;

    create a second VNS;

    obtain a second IP address from the second node;

    associate the second IP address with the second VNS; and

    initiate a second IP flow between the WTRU and the second node via a second connection corresponding to the second VNS, the second IP flow corresponding to a second application using the second VNS, the first connection corresponding to the first VNS being revockable and managed under a first Quality of Service (QoS) and the second connection corresponding to the second VNS being revockable and managed under a second QoS, wherein the revocability of the first connection corresponding to the first VNS is independent from the revocability of the second connection corresponding to the second VNS.
