摘要： An aspect of the disclosure provides for a method for user equipment (UE) internet protocol (IP) address management. The method includes sending by an application function (AF), a request to a policy control function (PCF), the request including information identifying traffic and an indication that a UE IP address associated with the traffic should be preserved. The method further includes sending by the PCF, to a session management function (SMF) being responsible for managing a Protocol Data Unit (PDU) session associated with the traffic, a policy and charging control (PCC) rule including the indication. In some embodiments, the request is sent by the AF to the PCF via a network exposure function (NEF). In some embodiments, the method further includes managing, by the SMF, the UE IP address according to the PCC rule. In some embodiments, the managing includes preserving the UE IP address for a PDU session associated with the traffic. In some embodiments, the preserving includes preventing reselection of a protocol data unit (PDU) session anchor (PSA) to which the UE IP address is associated.

摘要： Methods and apparatus for management of network slices in a communication network such as a 5th generation wireless communication network are provided. Management planes may be provided which are separate from the plurality of network slices. A connection manager residing in a management plane receives an indication that a mobile device is to be associated with the communication network. The connection manager may reside at an access node or in the core network. A network slice is determined, and the connection manager transmits instructions, to one or more network nodes, to associate the mobile device with the network slice. The instructions may be provided to a local connection manager. The slice may be requested explicitly by the mobile device, or determined based on device and/or network requirements.

摘要： Methods, systems and architectures are described which provide at least one aggregated tunnel protocol, in addition to the existing per PDU session tunnel protocols (1, 2, . . . N). When the UE requests a new PDU session or a new QoS flow, the SMF may establish a Per PDU Session Tunnel to serve this PDU session. Alternatively, an Aggregated Tunnel may be selected to serve the PDU session or to serve the QoS flow. When a packet from a UE arrives, the receiving network function can send this packet either using a per PDU session tunnel protocol or aggregated tunnel protocol.

摘要： Methods and apparatus for managing data content among in-network caches of a communication network are provided. In some embodiments, multiple registers are maintained for indexing cached data content. Different data content is indexed in different registers based on parameters such as popularity or content freshness. Customized popularity estimators can be applied to each register, and data content may be indexed by different registers as parameters change. Less popular content can be removed from caches as required. In some embodiments, caches can be grouped into clusters, and deletion of data content from a cache may be modified or inhibited if the cluster still requires a copy of that data content. Data content can be moved between caches of a cluster based on popularity.

摘要： There is provided systems and methods for Network Function Virtualization (NFV) in a control plane. The NFV framework is be used to define a plurality of virtual network functions (VNFs), each of which can correspond to a function enabling operation of a communication network. There is provided a method and system for managing a plurality of network slices in a communication network, the method comprising: instantiating a Global Control Plane set apart from the plurality of network slices, the Global Control Plane configured to at least partially manage each of the plurality of network slices.
