  • Patent number: 9131391
    Abstract: A method of dynamically adjusting Wi-Fi parameters of a plurality of access points (APs) is disclosed. Reports from the plurality of APs are received through an interface. A conflict graph is created by a processor. Creating the conflict graph includes creating a plurality of vertices of the conflict graph, each vertex corresponding to one of the plurality of APs. Creating the conflict graph further includes determining that there is a conflict between at least some of the pairs of APs based at least in part on the received reports. Creating the conflict graph includes connecting an edge between each of the at least some of the pairs of APs. The conflict graph is stored in a memory.

  • Patent number: 9131392
    Abstract: A method of detecting a hidden node is disclosed. Reports from a plurality of access points (APs) are received. The method includes determining that transmissions from a second AP are not detected by a first AP based on the received report from the first AP. The method includes determining that transmissions from a client associated with the first AP are detected by the second AP based on the received report from the second AP. The method further includes detecting that the second AP is a hidden node, wherein transmissions from the hidden node interfere with transmissions between the client and the first AP, and wherein the detection is based at least in part on the determination that transmissions from the second AP are not detected by the first AP and the determination that transmissions from the client associated with the first AP are detected by the second AP.

  • Patent number: 9066251
    Abstract: A method of managing Wi-Fi access points (APs) includes selecting between a global optimization and a local optimization of AP parameters based at least in part on one or more factors. The method includes causing a global optimization to be performed in the event that a global optimization is selected, the global optimization comprising: searching for adjustments to a first set of AP parameters that optimize an overall performance associated with a global region, the global region including a first set of APs. The method includes causing a local optimization to be performed in the event that a local optimization is selected, the local optimization comprising: searching for adjustments to a second set of AP parameters that optimize an overall performance associated with a localized region, the localized region including a second set of APs, wherein the second set of APs comprises a subset of the first set of APs.

  • Patent number: 9060289
    Abstract: A method of configuring small cell base stations in a cellular network is disclosed. A constraint on a performance-related metric associated with at least a portion of the cellular network is received. In some embodiments, the constraint on the performance-related metric comprises a constraint on a performance-related metric associated with one or more macrocells. Measurement data from one or more small cell base stations is received via a control interface. One or more optimized values of one or more parameters associated with one or more small cell base stations are searched. The searching is based at least in part on the received measurement data and subject to the constraint on the performance-related metric associated with the at least a portion of the cellular network. The one or more optimized values of the one or more parameters to the associated small cell base stations are transmitted.

  • Patent number: 8867490
    Abstract: A method of offloading data from an IP-based cellular network to a Wi-Fi network is disclosed. A request from a user equipment (UE) to connect to a Wi-Fi network is received. It is determined whether the UE is a subscriber to a cellular network. It is determined whether to offload data from the cellular network to the Wi-Fi network. The determination is based at least in part on a set of offload criteria. A Home IP Address is obtained, wherein the Home IP Address comprises a mobile IP address corresponding to the UE assigned by the cellular network. The Home IP Address is allocated to the UE as the UE's IP address for communicating with the UE on the Wi-Fi network. Data is offloaded from the cellular network to the Wi-Fi network.

  • Publication number: 20130077482
    Abstract: A method of handing off between a cellular network and a Wi-Fi network is disclosed. A cellular base station of the cellular network is caused to collect information related to the cellular network. A Wi-Fi access point of the Wi-Fi network is caused to collect information related to the Wi-Fi network, wherein the cellular base station and the Wi-Fi access point are co-located. The information related to the cellular network and the information related to the Wi-Fi network are used collectively for determining whether to handoff traffic of a user equipment from a cellular air interface of the cellular network to a Wi-Fi air interface of the Wi-Fi network, or vice versa.
