    摘要： Methods by which User Plane (UP) management information is exchanged between an Application Function (AF) supporting one or more applications and a Slice Management Function (SW) configured to manage traffic flows in a given slice of the network. The exchange of UP management information may be initiated from either the AF or the SW. In the case of AF-initiated information exchange, the UP management information provided by the AF may comprise traffic requirements of applications supported by the AF. In the case of SMF-initiated information exchange, the UP management information provided by the SM may comprise operator policy information or events, and the AF may respond with information of traffic requirements of applications supported by the AF.

    摘要： A method for optimizing operation of a user equipment (UE) in a wireless communications network. The method, performed at a network function (NF), comprises: transmitting along the network at least one rule of at least one policy that governs how the UE exchanges packets along the network and that contains information conditioned on at least one information element, such that: if the information conditioned on the at least one information element is contained in the at least one rule and the UE does not satisfy the information contained in the at least one rule, the UE is precluded from exchanging packets in accordance with the at least one rule; if the information conditioned on the at least one information element is contained in the at least one rule and the UE satisfies the information contained in the at least one rule, the UE exchanges packets in accordance with any constraints contained in the at least one rule; and if there is no information in the at least one rule corresponding to the at least one information element, the UE exchanges packets in accordance with any constraints contained in the at least one rule.

    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： Systems and methods for performing User Plane (UP) path selection or reselection over a communications network with a 3rd party entity, and for notifying network entities of UP changes in a communications network, are disclosed. The method includes: receiving an application program interface based request for UP path selection from the 3rd party entity; performing a validation and authorization procedure with the request; transmitting a UP path selection configuration request to a Control Plane Function that maintains configuration data; obtaining a reference number confirming the UP path selection configuration request; and installing the UP path selection according to the reference number.
