    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 and system of unifying data transmission and storage in a communication network are provided. The method comprises determining, by a coordinator associated with a network data analytics function (NWDAF) service instance set, what data that more than one NWDAF service instances in the NWDAF service instance set requires, if the data required by the more than one NWDAF service instances is the same, requesting, by the coordinator associated with the NWDAF service instance set, the data from a network function service instance set, and receiving the data from a data storage function that is notified by the network function service instance set of the request from the coordinator associated with the NWDAF service instance set.

    摘要: Upon receiving a request for a virtual network and before admitting the requested virtual network, a virtual service provider controller may assess the ability of the virtual service provider network to meet conditions specified in the request. In particular, the virtual service provider controller may consider details of the traffic expected in the requested virtual network in the context of existing traffic on the virtual service provider network. Consideration may be given to geographic distribution of traffic, type of traffic, and key performance indices. Indeed, traffic of different types may be homogenized through the use of weighting factors to simplify the assessment. Upon determining that the virtual service provider network may not be able to meet the conditions, the virtual service provider controller may attempt to obtain additional resources from an infra-structure provider network or may attempt to adjust resources allocated to already admitted virtual networks.

    摘要: A plurality of methods for unicast and group communication delivery of Downlink (DL) group communication data to a plurality of User Equipment's (UEs) are used by embodiments of this invention. These methods include two architectures wherein both architectures include a first AMF, AMF-1, which has an N1 connection to UE and both AMF-1 and a second AMF, the network control function, have an N2 connection to the RAN. In the first architecture, AMF-1 supports unicast data delivery and a second AMF, the network control function, supports GC data delivery. AMF-1 and the network control function have no direct connection between each other in the first architecture. In the second architecture, AMF-1 supports unicast data delivery and the network control function supports group communication data delivery. In the second architecture, the network control function and AMF-1 are connected by an interface.

    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: A network data analytics (NWDA) function and method of policy optimization in a communication network are provided. The NWDA performs data analytics on the communication network traffic, and includes communication interfaces to connect to other network elements in the communication network. The method comprises the NWDA function configured to receive a request for a policy input, send instructions to network elements to obtain network performance measurement data, receive the measurement data from the network elements, and transmit a policy input based on the received measurement data.
