摘要： Methods(1100) and System(100) for enhanced navigation and traffic management are provided. A controller(102) obtains input indicative of conditions on a physical road, traffic status information associated with the physical road and requirements of a mobile device(1102). Based at least in part on the input, one or more virtual lanes defining respective routes along the physical road are determined(1104). The virtual lanes are communicated to mobile devices which follow them in place of painted lanes. The virtual lanes can be dynamically updated for example to avoid obstacles. Different lanes can correspond to different priorities of traffic.

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： A method, apparatus and system for supporting Mobile Edge Computing (MEC) in a network such as a 5G communication network. Application Function (AF) request data is received from an AF operating in the network in support of MEC, stored in memory, and transmitted from the memory to one or more Policy Control Functions (PCFs) operating in the network. Subscribing PCFs may be notified of the receipt and storage of the data and request retrieval of the data. The data may be stored and handled by a function referred to as the Application Data Repository, or by another data repository. The operations may be performed by a network function such as but not limited to an Application Data Repository function. The function can store the AF request data and notify the PCFs. The function can handle AF requests associated with roaming UEs.

摘要： Routing packets through a virtual network (VN) in support of service-based traffic forwarding is provided. Data packets are routed using a virtual router (v-router) toward a destination end point over a pre-configured VN. The v-router is associated with a VN node, which is associated with a physical network node (NN). A data packet associated with the VN is received and a name identifier of the destination end point is specified. A location corresponding to the name identifier is obtained. An indication of a destination VN node corresponding to the location is obtained. An indication of a next VN node on a path between the virtual router and the destination VN node is obtained. The indication of the next VN node is inserted into the packet to produce a routed packet. The routed packet is submitted to the associated NN for transmission toward the next node.

摘要： A method and apparatus for routing packets to a destination end point over a virtual network (VN) pre-configured on a network. The routing is performed by a VN virtual router (v-router) associated with a node of the VN. The v-router receives a data packet, obtains an indication of location of the destination end point from a connection management (CM) entity tracking the end point, and selects a logical tunnel or next VN node to forward the data packet to. The CM entity tracks end points upon registration and provides updates upon a request or other trigger.

摘要： The present application provides a method for routing traffic from a user equipment (UE) to a service available on a network. In the method, a virtual router entity that services a virtual network available on the network receives a packet from the UE, the received packet including at least a destination ID and payload. The virtual router then forwards a location resolution request including the received destination ID to an associated connectivity manager operating on the network. The virtual router receives a location resolution response from the connectivity manager including at least a destination network node ID. The virtual router may then forward the packet to the destination network node ID.

摘要： A method for tracking a location of a User Equipment (UE) connected to a network is provided. When the UE is in an IDLE state, and a mobility management entity of the network receives a notification message that downlink data is available for the UE, the mobility management entity may transmit paging instructions to access points in a paging area. The paging area may be defined as one or more access points within one or more tracking areas. The tracking areas may be defined as a one or more access points from which the UE can access the network. The paging areas may further be defined by a mobility pattern of the UE that tracks location and mobility behaviour of the UE.

摘要： An improved system and method for providing data analytics management (DAM), in particular for wireless networks having multiple domains, is disclosed. Some embodiments utilize a hierarchical DAM structure. Such a hierarchy includes a Global DAM function which provides inter network DAM, and domain DAM functions which provide intra network DAM. Some embodiments utilize a plurality of local DAM functions within a domain. In some embodiments. the global DAM can be implemented by a third party. In other embodiments, different networks inter operate by utilizing virtual network slices over non-owned infrastructure to provide what appears to be a global network by each operator. For such embodiments, DAM can be performed on a per slice basis.
