Abstract: 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.

Abstract: Systems and methods described for providing capacity and coverage hole analysis in next generation wireless networks (e.g. 5G networks). Provided is a network function comprising a network interface for receiving data from, and transmitting data to, a plurality of network functions connected to a within a communication network; a processor; and a non-transient memory for storing instructions executable by the processor to cause the network function to receive a request for capacity and coverage hole (CCH) information from a capacity and coverage hole analysis (CCHA) consumer, collect the CCH information responsive to the request; and determine a capacity and coverage hole profile that is indicative of at least one of a network coverage sufficiency and coverage service quality based at least in part on the CCH information.

Abstract: A method and apparatus for pre-configuring a communication network to support delivery of a service to an end point associated with the service is provided. A virtual network (VN) having a plurality of VN nodes is provided and associated with a respective plurality of physical network nodes of the communication network. Logical tunnels communicatively interconnect the VN nodes. VN virtual routers (v-routers) associated with the VN nodes are provided and configured to route packets between the VN nodes via the logical tunnels. Edge nodes of the communication network are configured to monitor for a packet associated with the service, and to submit the packet to the VN for handling thereby.

Abstract: A communication service manager (CSM) apparatus for monitoring a communication network is provided. The CSM receives configuration instruction message from a higher-level device, and creates or modifies a set of tasks based on the configuration instruction message. The CSM is thus configured to interact with data provider devices to obtain specific information, process the information, and report the results of the processing operations toward a specified device or database. The data provider devices monitor network operations and may include network functions and data analytics manager (DAM) functions. A format for configuration instruction messages, for configuring the CSM, is also provided.

Abstract: A method and system for responding to demand-based charging in a communication network, such as a 5G wireless communication network. Service providers and/or infrastructure providers adjust network usage pricing dynamically based on demand. Customers such as Virtual Network operators respond to pricing adjustments by adjusting their network usage, service requirements, and/or by re-negotiating the pricing structure. Network usage can be adjusted by controlling network traffic generated in response to activity of end-user devices of the Virtual Network.

Abstract: A method for managing network slice enabled traffic on a communications network is disclosed. The network slice is instantiated on the communications network for providing connectivity resources to a network operator using the communications network. The method comprises measuring a traffic level indicative of the traffic enabled by the network slice; and adjusting the traffic enabled by the network slice in accordance with the traffic level and a network operator enabled function associated with the network slice.
