  • Patent number: 9722887
    Abstract: A device is configured to receive packet timing data, from multiple network devices, for subscriber application traffic over an Internet Protocol (IP) wireless access network and to calculate, based on the packet timing data, timing latencies for a particular subscriber flow. The device is configured to retrieve Quality of Service (QoS) timing specifications for the particular subscriber flow and to determine when the calculated timing latencies for the particular subscriber flow fail to meet the QoS timing specifications for the particular subscriber flow. The device is configured to identify one or more of the network devices that are causing the particular subscriber flow to fail to meet the QoS timing specifications and to instruct the one or more of the network devices to modify QoS parameters for the particular subscriber flow to improve timing latency for the particular subscriber flow.

  • Patent number: 9642059
    Abstract: A method and system for coordinated interference suppression in a communication system. The communication system implements at least a first radio access technology via a first base station and a second radio access technology via a second base station. The first and second radio access technologies differ from one another. Information relating to an interference signal received at the first base station via the first radio access technology is received at the second base station from a first device associated with the first base station. At a second device associated with the second base station, an interfering user equipment accessing the second base station via the second radio access technology is identified. The identification is based on the information received from the first device associated with the first base station. Interference caused by the identified interfering user equipment is suppressed by the second base station.

  • Patent number: 9622265
    Abstract: Embodiments are provided for implementing a CSMA-CA half window scheme in 802.11 networks or other suitable wireless networks that could benefit from such scheme. The half window scheme improves a back-off time calculation by adding a probability prediction factor. The back-off time is part of a delay time in accessing a wireless transmission medium by a station (STA). The probability prediction factor is used to adjust a contention widow (CW) used to calculate the back-off time, based on the STA's medium access probability. The STA splits the CW into two at least half windows and then chooses one of the windows according to the window's information gain for the probability prediction. The selected window is used to select a random number for the back-off time. The improved back-off time calculation reduces contention between STAs in accessing the medium.

  • Patent number: 9608900
    Abstract: Techniques are provided for generating efficient flooding tree paths in a network. At a node device in a network, a unicast message is sent to a plurality of node devices in the network. The node device obtains an identifier associated with each of the node devices in the network. The identifier contains information indicating node connectivity for each of the node devices. A selected node device is then identified. The selected node device is one of the node devices in the network that has a lowest identifier value indicating a lowest number of connected node devices to the selected node device in the network. The selected node device is classified as a root flooding tree node device. A flooding tree is generated by performing a shortest path first operation from the selected node device to the plurality of node devices in the network.
