摘要： 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.

摘要： 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.

摘要： Embodiments contemplate network stack virtualization which may be virtualization of a portion of the communication stack, such as the protocol stack, in some embodiments, multiple functionally of independent copies of the protocol stack may be simultaneously running on the terminal and/or serving the needs of different applications. This may allow independent operation from the application point of view, including connectivity to different networks with different identities. Embodiments contemplate that any number of such virtual network stacks can be instantiated, perhaps in some embodiments depending on the characteristics of an active application. Embodiments also contemplate the presentation of multiple allocated internet protocol (IP) addresses that may have sufficient information to enable an intelligent source IP address selection on the WTRU. The WTRU may be able to select an optimum IP address, perhaps in some embodiments depending on which application may be started.
摘要翻译：实施例考虑网络堆栈虚拟化，其可以是通信栈的一部分的虚拟化，例如协议栈，在一些实施例中，协议栈的独立副本的多个功能可以同时在终端上运行和/或满足不同的应用。这可能允许从应用的角度进行独立操作，包括连接到具有不同身份的不同网络。实施例考虑到任何数量的这样的虚拟网络栈可以被实例化，或许在一些实施例中取决于活动应用的特性。实施例还考虑了可以具有足够信息以实现WTRU上的智能源IP地址选择的多个分配的因特网协议（IP）地址的呈现。 WTRU可能能够选择最佳IP地址，在一些实施例中，取决于可以开始哪个应用。

摘要： Control and/or management plane interactions may be implemented between one or more wireless backhaul links and respective associated access and/or core networks. The control and/or management plane interactions may be implemented in accordance with self-optimization functionalities and may be implemented to perform radio resource management (RRM) for the one or more wireless backhaul links. Packet-based synchronization and/or delay measurement techniques may be implemented to determine estimated values for wireless backhaul induced delay. The delay estimation information may be used by one or more devices in a wireless communications network, such as a packet data network gateway (PGW), a small cell gateway (SC GW), or an access point (AP), such as a small cell access point (SC AP). Delay estimation for wireless backhaul links may be implemented in accordance with PTP message replication and/or side-channel signaling, dual synchronization with GPS and PTP signaling, and/or timestamping.
摘要翻译：可以在一个或多个无线回程链路和相应的相关联的接入和/或核心网络之间实现控制和/或管理平面交互。控制和/或管理平面交互可以根据自身优化功能来实现，并且可以被实现为对一个或多个无线回程链路执行无线电资源管理（RRM）。基于分组的同步和/或延迟测量技术可以被实现以确定无线回程感应延迟的估计值。延迟估计信息可以由诸如分组数据网络网关（PGW），小型小区网关（SC GW）或接入点（AP）的无线通信网络中的一个或多个设备使用，诸如小型小区接入点（SC AP）。无线回程链路的延迟估计可以根据PTP消息复制和/或侧信道信令，与GPS和PTP信令的双重同步和/或时间戳来实现。
