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： Application Function (AF) influenced routing for peer-to-peer (P2P) communications is provided. Core network elements correlate PDU sessions and optimize the UP path for peer-to-peer traffic. UP selection, reselection, configuration or reconfiguration can be performed in support of P2P traffic routing. P2P traffic between a pair of UEs is routed or rerouted through a bridge. The bridge may be established between the first UP and the second UP, and/or between associated RAN nodes. One or more application functions can be included along the bridge path. A policy control function (PCF) directs underlying resources to route P2P traffic via the bridge, for example in response to a trigger from the AF. A session management function (SMF) directs underlying resources to configure or reconfigure user plane data paths to route P2P traffic via the bridge. First and second SMFs of the first and second UPs can cooperate to establish the desired traffic routing. One or more UPFs can be configured to support P2P traffic detection.

摘要： An aspect of the disclosure provides a method of network slice management performed by a Communication Service Management Function (CSMF). The method includes receiving service requirements and receiving capability exposure information. The method further includes transmitting network slice requirements in accordance with the service requirements and capability exposure information. In some embodiments the capability exposure information is received from a Network Slice Management Function (NSMF). In some embodiments the network slice requirements are transmitted to the NSMF. Other aspects are directed to methods implemented by an NSMF and a Network Sub-Slice Management Function (NSSMF). Other aspects are directed to the network functions themselves.

摘要： Methods and apparatus for supporting customer charging in 5G networks are provided. Monitoring functions are instantiated at selected network locations for tracking access to network services. The monitoring functions provide charging information for use in customer billing. A customer can enter a service level agreement with a particular customized method of charging for service usage, and the monitoring functions can be customized to provide charging information according to the service level agreement. Charging can vary based on factors such as time of day, network congestion, service traffic characteristics, and geographic location.

摘要： Embodiments provide systems and methods for managing resources in networks which utilize network slicing. Embodiments include systems and methods for monitoring performance in networks which utilize network slicing when the resources of a network domain are allocated to more than one slice. Embodiments include systems and methods for monitoring performance when resources of a slice are controlled by different network operators/service providers. A domain manager can make the performance measurement data available per network allotment instance with an identifier indicating to which virtual network service the performance measurement data belongs.

摘要： Aspects of the disclosure provide architectures, methods and systems that will allow reconfigurability of the network to suit the needs of various parties. Accordingly, some embodiments provide a controllable open operation environment. In such an environment, there can be a decoupling of various network aspects which would be conventionally be under the span of control of a service provider, allowing for each aspect to be provided by a different entity. For example, infrastructure can be provided separately from the provider of network services to subscribers and/or from the provider of slices and/or from the provider of NOS services. For example an infrastructure provider can provide infrastructure used by a slice provider to provide network slices to virtual network providers which provide services to end customers. Generally speaking, SONAC-Com is responsible for the composition of slices and manages resources at the slice level. SONAC-Op is responsible for the operation of slices. For example, SONAC-Com develops slices using the general infrastructure resource pools, while SONAC-Op manages the delivery of slice traffic packets over deployed slices.

摘要： Methods and systems are disclosed which can reduce energy and overhead information by reducing the need for a UE to decode every (System Information Block) SIB from overhead signaling for every cell for every cell reselection. Instead the UE can determine information from Physical Cell ID (PCI) information received by the map download and update procedures described herein. A map contains a list of cells including cell-specific system information including location; it may also be associated with a geographic boundary. In the map, each 3GPP cell is indexed by PCI (physical cell id). In some embodiments the UE retrieves dynamic information from the Master Information Block (MIB) to determine what SIB information needs to be decoded. Furthermore, in some embodiments, this can be applied for both 3GPP cells and non-3GPP cells.
