  • Patent number: 11240644
    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.

  • Patent number: 11071020
    Abstract: Interference costs on virtual radio interfaces can be modeled as a function of loading in a wireless network to estimate changes in spectral efficiency and/or resource availability that would result from a provisioning decision. In one example, this modeling is achieved through cost functions that are developed from historical and/or simulated resource cost data corresponding to the wireless network. The cost data may include interference data, spectral efficiency data, and/or loading data for various links over a common period of time (e.g., a month, a year, etc.), and may be analyzed and/or consolidated to obtain correlations between interference costs and loading on the various links in the network. As an example, a cost function may specify an interference cost on one virtual link as a function of loading on one or more neighboring virtual links.

  • Patent number: 10892949
    Abstract: A telecom connectivity service provider (TCSP) and a method for allocating an infrastructure resource to a virtual network operator (VNO). A TCSP control element sends to a downstream control element, a request for a portion of the infrastructure to be allocated to the TCSP by an infrastructure provider (InP) and receives a response from the downstream control element providing access to and control of the allocated infrastructure. The TCSP control element can pool the allocated infrastructure with other resources allocated to the TCSP and/or communicate with an upstream control element for providing access to and control of the allocated infrastructure to the VNO. The downstream control element is a local InP control element or a downstream TCSP control element. The upstream control element is a VNO control element or an upstream TCSP control element.

  • Patent number: 10887118
    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.

  • Patent number: 10855340
    Abstract: Embodiments are provided for uplink measurement based mechanism and control using user equipment (UE) centric sounding signals. The mechanism provides an alternative to DL-measurement dominated system control. Based on UL-measurements at TPs, the network obtains knowledge of users' channel and timing information, traffic, and interference, and is thus able to perform better control, including TP and UE clustering and optimization, and power control and link adaptation. In an embodiment method, a TP receives one-to-one mapping information indicating a plurality of UE IDs and a plurality of sounding channels assigned to the corresponding UE IDs. When the TP detects a sounding reference signal (SRS) from a UE, the TP is able to identify the UE using the detected SRS and the one-to-one mapping information. The TP then obtains measurement information for the identified UE, enabling better control and communications for uplink and downlink transmissions between multiple TPs and the UE.
