Abstract
A method and apparatus are described for supporting advanced distributed and dynamic mobility management (DMM) features with multiple flows anchored at different gateways. A software defined networking (SDN) controller may support the attachment of a wireless transmit/receive unit (WTRU) to a network. The SDN controller may receive initial attachment signaling from a point of attachment (PoA) indicating that the WTRU initially attached to the network. The anchor node may be a distributed gateway (D-GW). The SDN controller may select an anchor node to serve the WTRU Internet protocol (IP) flow traffic. Initial attachment signaling, intra-anchor node handover, inter-anchor node handover, new anchor node allocation and inter-domain mobility across virtualized operators are also described.
