  • Patent number: 9629061
    Abstract: A wireless communication access path exists between an ingress station and an egress station. A logical communication tunnel is established between the ingress and egress stations directly or through any number of intermediate relay stations to handle session flows of PDUs. As PDUs arrive, the ingress station may determine and add information bearing on an identified QoS associated with the PDU to the PDUs before they are delivered to the downstream egress station(s) or intermediate relay station(s). The information may be used by the downstream stations to schedule the PDUs for further delivery. The information may also be used by the egress station to schedule the PDUs for delivery.

  • Publication number: 20170019817
    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.

  • Publication number: 20170012751
    Abstract: Backhaul resource utilization efficiency can be improved by performing lower-layer decoding of uplink transmissions at access points to obtain transport blocks carried by the uplink transmissions, and then strategically scheduling the transport blocks over backhaul links extending between the access points and network nodes. Upon reception, the network nodes may perform radio link control (RLC) decoding of the transport blocks to obtain the uplink data. Transport blocks may be scheduled a manner that prioritizes time-sensitive data (e.g., voice traffic), or in a manner that strategically routes transport blocks over backhaul paths to increase the overall utilization of backhaul resources.

  • Publication number: 20170012678
    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.

  • Publication number: 20160366623
    Abstract: Predicting mobile station migration between geographical locations of a wireless network can be achieved using a migration probability database. The database can be generated based on statistical information relating to the wireless network, such as historical migration patterns and associated mobility information (e.g., velocities, bin location, etc.). The migration probability database consolidates the statistical information into mobility prediction functions for estimating migration probabilities/trajectories based on dynamically reported mobility parameters. By example, mobility prediction functions can compute a likelihood that a mobile station will migrate between geographic regions based on a velocity of the mobile station. Accurate mobility prediction may improve resource provisioning efficiency during admission control and path selection, and can also be used to dynamically adjust handover margins.

  • Publication number: 20160359725
    Abstract: Increased resource utilization efficiency can be improved by modeling path costs during admission and path-selection. Specifically, path costs for candidate paths are modeled based on load characteristics (e.g., current load, load variation, etc.) of links in the candidate paths. Path costs can represent any quantifiable cost or liability associated with transporting a service flow over the corresponding path. For example, path costs can correspond to a probability that at least one link in the path will experience an outage when transporting the service flow, a price charged by a network operator (NTO) for transporting the traffic flow over the candidate path, or a total network cost for transporting the flow over a candidate path. The candidate path having the lowest path cost is selected to transport a service flow.

  • Publication number: 20160360408
    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.
