  • Patent number: 10298713
    Abstract: Network caching performance can be improved by allowing users to discover distributed cache locations storing content of a central content server. Specifically, retrieving the content from a distributed cache proximately located to the user, rather than from the central content server, may allow for faster content delivery, while also consuming fewer network resources. Content can be associated with distributed cache locations storing that content by cache location tables, which may be maintained at intermediate network nodes, such as border routers and other devices positioned in-between end-users and central content servers. Upon receiving a query, the intermediate network nodes may determine whether the content requested by the query is associated with a cache location in the cache location table, and if so, provide the user with a query response identifying the associated cache location.

  • Patent number: 10298580
    Abstract: An aspect of the disclosure provides a method for session admission at a node in an infrastructure provider network. The method includes receiving a connection request from a user equipment not associated with a network with which the infrastructure provider network is associated and obtaining from the user equipment, an identification of a service provider with which the infrastructure provider network is associated. Access authorization is then requested from the identified service provider. Embodiments allow such a process to provide government mandated free access, or for some other service provider to pay for the service.

  • Patent number: 10212097
    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.

  • Patent number: 10193813
    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.

    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.

  • Patent number: 10123205
    Abstract: An aspect of the disclosure provides a method of admitting a session from a user device subscribed to a service with a virtual network operator. The method includes receiving a service request from said user device at an Access Point and selecting a network function Authentication and Authorization (AA) function (AAF) to confirm the user device is authorized for the requested service, and transmitting the request to the selected network function AAA function. The AAAF which processes the request may reside with the virtual network operator (VNO). However, the VNO may share its AAA database with other network entities (for example, Telecom Connectivity Service Providers (TCSPs) or InPs), and allow those entities to perform the AAA functions.

  • Publication number: 20180317230
    Abstract: 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.
