SOFTWARE DEFINED NETWORKING DISTRIBUTED AND DYNAMIC MOBILITY MANAGEMENT
First Claim
1. A method for use in a software defined network (SDN) controller of a network, comprising:
- receiving an initial attachment signaling from a first point of attachment (PoA) node indicating that a wireless transmit receive unit (WTRU) is attached to the network;
determining if the WTRU is currently attached to the network by checking a database;
selecting a first anchor node to provide connectivity to the WTRU, wherein the selecting the first anchor node is based on at least one of the following criteria;
expected mobility patterns of the WTRU, known mobility patterns of the WTRU, speed of the WTRU, status of the network, load of the network, or capabilities of the network;
configuring a forwarding data plan plane to allow signaling to reach the first anchor node; and
configuring the forwarding data plane between the first anchor node and the WTRU to allow data packets to be forwarded between the WTRU and the first anchor node.

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.

11. A software defined network (SDN) controller, comprising:
-
a processor and a transceiver configured to receive an initial attachment signal from a first point of attachment (PoA) node indicating that a wireless transmit/receive unit (WTRU) is attached to the network; the processor and the transceiver configured to determine if the WTRU is currently attached to the network by checking a database; the processor and the transceiver configured to select a first anchor node to provide connectivity to the WTRU, wherein the processor and the transceiver are configured to select the first anchor node based on at least one of the following criteria;
expected mobility patterns of the WTRU, known mobility patterns of the WTRU, speed of the WTRU, status of the network, load of the network, or capabilities of the network;the processor and the transceiver configured to determine a forwarding data plan plane to allow signaling to reach the first anchor node; and the processor and the transceiver configured to determine the forwarding data plan plane between the first anchor node and the WTRU to allow data packets to be forwarded between the WTRU and the first anchor node. - View Dependent Claims (12, 13, 14, 15, 16, 17)
