Abstract: Methods, apparatus and systems may support distributed and dynamic mobility management features, including for nodes, functions and interfaces. A distributed gateway (D-GW), which may be a logical entity, may implement functionality of a PDN gateway (PGW) along with additional functionality that may support distributed mobility management (DMM). Additionally, methods, apparatus, and systems may support detecting and discovering capabilities that may be used to support dynamic IP mobility features on mobile node and networks.

Abstract: A device and method for registering devices on advanced networks as well as providing operative communications between a legacy device and a advanced network. The legacy device may contain data, such as sensor data, which is being collected on a network outside the communication range/abilities of the legacy device. An intermediary device may receive the data via a first communication scheme and send the device to a server collecting the data via a second communication scheme.

Abstract: Systems, methods, and instrumentalities are disclosed that provide for a gateway outside of a network domain to provide services to a plurality of devices. For example, the gateway may act as a management entity or as a proxy for the network domain. As a management entity, the gateway may perform a security function relating to each of the plurality of devices. The gateway may perform the security function without the network domain participating or having knowledge of the particular devices. As a proxy for the network, the gateway may receive a command from the network domain to perform a security function relating to each of a plurality of devices. The network may know the identity of each of the plurality of devices. The gateway may perform the security function for each of the plurality of devices and aggregate related information before sending the information to the network domain.

Abstract: A method and apparatus for offloading backhaul traffic are disclosed. A first base station may detect a condition triggering backhaul traffic offloading for a wireless transmit/receive unit (WTRU). The first base station may establish a wireless connection with a second base station, and offload at least one bearer of the WTRU onto the second base station via the wireless connection. The first base station may be a macro-cell base station and the second base station may be a femto-cell base station having a wired connection to Internet and a mobile operator core network. The first or second base station may include a relay functionality and act as a relay between the WTRU and the other base station. The backhaul link may be established using a Uu, Un, X2 interface or any other interface over a licensed or license-exempt frequency, a TV white space frequency, etc.

Abstract: A bandwidth management (BWM) controller may provide the capability to combine a lower speed, wide area network (WAN) that may have connectivity with an opportunistic network (ONW) that may have intermittent connectivity. This may be done, for example, to generate a multi-connection service that may provide connectivity that may take advantage of occasional high-speed ONW connection events.

Abstract: A method and apparatus for power control for distributed wireless communication is disclosed including one or more power control loops associated with a wireless transmit/receive unit (WTRU). Each power control loop may include open loop power control or closed loop power control. A multi-phase power control method is also disclosed with each phase representing a different time interval and a WTRU sends transmissions at different power levels to different set of node-Bs or relay stations during different phases to optimize communications.

Abstract: Systems, methods, and instrumentalities are described to implement reporting of surveillance information associated with a device. A gateway device may intercept a communication associated with the device. The gateway device may route the communication such that the communication bypasses a core network. The gateway device may report information associated with the communication to a core network entity. The gateway device may receive a command message. The command message may include a request for a surveillance status of the device. The gateway device may send a response message. The response message may indicate a surveillance status of the device. The gateway device may receive an activate surveillance signal for the device. The gateway device may receive a deactivate surveillance signal for the device. Upon receiving the deactivate surveillance signal, the gateway device may stop further reporting.
