  • Publication number: 20170359749
    Abstract: Methods for quality of service monitoring, policy enforcement, and charging in a communications network, are disclosed. The methods include mapping quality of service parameters to measured parameters of a real-time video or packet data unit flow. The mapping may be used to monitor bursty traffic to adhere to quality of service requirements, perform traffic shaping, and for use in reporting certain network events. The measured parameters of real-time packet data unit flow include a first bit rate measured over a short-term measurement window and a second bit rate measured over a long-term measurement window. The short-term and long-term measurement windows are differently sized.

  • Publication number: 20170332282
    Abstract: The present application provides a channel type used to support user QoE expectations, which is, in particular, a QoS and QoE guaranteed channel (QQGC). Also provided is a related method and system for providing a QQGC. Effective bit rate (EBR), average bit rate, and maximum bit rate, are determined and used to support the channel. The EBR can be determined based on QoE reports. An application function, such as a network data analytics function provides the indication of effective bit rate. One or more portions of the application function can be provided in potentially different locations of a communications network and operatively coupled. Alternatively, application function portions can be co-located. The EBR is provided to and used by devices in the network to reserve user plane resources to support data flows at the EBR. The EBR can also be used for admission or rejection of requests for a QQGC channel.

  • Publication number: 20170171114
    Abstract: Methods and apparatus for managing data content among in-network caches of a communication network are provided. In some embodiments, multiple registers are maintained for indexing cached data content. Different data content is indexed in different registers based on parameters such as popularity or content freshness. Customized popularity estimators can be applied to each register, and data content may be indexed by different registers as parameters change. Less popular content can be removed from caches as required. In some embodiments, caches can be grouped into clusters, and deletion of data content from a cache may be modified or inhibited if the cluster still requires a copy of that data content. Data content can be moved between caches of a cluster based on popularity.

A set of network nodes is identified such that, for each of a set of client device locations, and for at least a number c of the set of nodes, output of a coverage cost function is no greater than a threshold. The coverage cost function receives as input a client location and one of the nodes. The set of network caches are then located at the respective set of nodes. The set of network nodes can be selected from plural candidate sets based on a utility criterion. The candidate sets can be generated by successive addition and/or removal of nodes. Information obtained from a Traffic Engineering function can be used to direct selection of the set of nodes. A cache-client association can be generated for directing clients to particular caches.

    Abstract: Methods and apparatus for determining whether to admit a virtual network using a set of communication network resources are provided. Different network resources can be owned by different infrastructure providers. Virtual network requests include a spatial profile of traffic requirements to be accommodated, and a determination is made as to whether the request can be accommodated based on available network resources. The resources include available backhaul link capacities. The resources can include computing resources for supporting service functions of the virtual network. Monitored network resource usage and traffic corresponding to the virtual network can be used to adjust future requests and accommodations. When a virtual network cannot be accommodated, a counter-offer can be made. Accommodation may incorporate monetary considerations. A feasibility computation of the admission procedure is formulated.

  • Publication number: 20170099225
    Abstract: Embodiments are provided herein for a system and methods for real-time video (or other real-time traffic) delivery, e.g., for cellular or wireless networks. The schemes herein address real-time video delivery by a joint design of the radio resource scheduler and the video encoder at the network side, and of the decoder at the users' terminals. The system design reduces frame loss and hence improves user quality of experience. In an embodiment, a radio node detects a frame of a real-time traffic flow. Upon determining that a transmission deadline corresponding to a rate for real-time traffic flow does not support a size of the frame, the transmission deadline is extended according to the size of the frame and a size of a next frame. The frame and the next frame are scheduled for forwarding within the extended transmission deadline.
