    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.
