摘要: A network function and a method for associating a UE of a UE group to a PDU session with in a CN. The NF establishes a shared PDU session for the UE group before all of the UEs in the UE group register with the CN and binds a UE that has not yet registered with the CN to the shared PDU session when the UE registers with the CN, provided the UE will share at least one of a UL UP connection and a DL UP connection associated with the shared PDU session. The NF may be an SMF.

摘要: The present invention provides systems and methods and apparatuses for enabling private communication between user equipments (UEs) in a (LAN) UE group. The UEs in the (LAN) UE group can communicate with each other using IP and/or non-IP type communication services. The communications between these UEs may take place in the form of point to point (e.g. UE to UE) communication or point to multi-point communication (e.g. UE to multiple UEs) as opposed to UE to Data Network (DN) communication.

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: 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: A method of providing a network slice service includes a mobile network operator (MNO): providing one or more service profiles to a virtual service provider (VSP) serving a user population including a plurality of user devices, each service profile comprising attributes defining characteristics of a respective network slice service offered by the MNO, the network slice service comprising any one or more of: a Virtual Network with E2E service requirements; a Virtual Network with a specified network topology; and a virtualized infrastructure. The MNO receives a request for a selected network slice service from the VSP; determines whether or not the requested service can be provided; and responsive to determining that the requested service can be provided: sending a Service Level Agreement (SLA) for the network slice service to the VSP; and subsequently facilitating a network slice service instance in accordance with the SLA.
