  • Patent number: 10624153
    Abstract: According to one configuration, an access point control resource receives channel allocation information indicating a change to allocation of channels in a wireless band currently used by multiple wireless access points to communicate with multiple communication devices in a network. The access point control resource uses the channel allocation information to identify a particular wireless channel (such as a de-allocated wireless channel) to be terminated from use by the multiple wireless access points. In accordance with the channel allocation information, when vacating use of the de-allocated channel, the access point control resource controls an order of terminating use of the particular wireless channel by the multiple wireless access points.

  • Patent number: 10028193
    Abstract: A mobile computer device establishes a wireless communication link between the mobile computer device and a first access point of multiple access points in a network environment. While wirelessly connected to the first access point, the mobile computer device monitors communications from a set of neighboring access points including at least a second access point of the multiple access points. The mobile computer device transmits performance information derived from the monitored communications to a controller resource. To alleviate a current load on the first access point, the controller resource generates control information to terminate the wireless communication link between the mobile computer device and the first access point and establish a replacement wireless communication link between the mobile computer device and a second access point.

  • Patent number: 9942749
    Abstract: Sensor based information from a base station is received by a configuration management device and is used to determine orientation, altitude and/or location. In some embodiments, the configuration management device compares measurement based information to corresponding expected values in a deployment plan to determine whether or not the base station has been correctly deployed. In some embodiments, the configuration management device uses received sensor based information from a base station to control re-configuration of the base station, e.g., re-orient an antenna or change an antenna pattern.

  • Patent number: 9232364
    Abstract: A method, apparatus and computer-readable medium for improving push-to-talk call setup speed by disabling an idle mode of a mobile station are provided. According to the method, a deregistration request is received from a mobile station. The base station determines whether a push-to-talk service flow exists for the mobile station, based upon a unique identifier for push-to-talk service flow for the mobile station. If the service flow does exist, then the base station transmits a deregistration command to the mobile station including an action code that instructs the mobile station to disable its idle mode and change its mobility feature supported field to sleep only mode. Since the time required to transition from sleep mode to active mode is less than from idle mode to sleep mode, the push-to-talk call setup speed is improved.

  • Patent number: 8098748
    Abstract: Systems and methods of testing a wireless network are provided. Simulated user data, spread across all user data sub-carriers of all sub-channels of a frequency band assigned for transmissions, is transmitted by a number of base stations surrounding a base station under test. The power level of the simulated user data is determined based on a selected network load. A mobile station receives signals from the base station under test and the number of base stations, and the interference caused by the simulated user data to the transmission from the base station under test is determined. When less than 100% loading is employed for testing, the sub-channels carrying the simulated user data can vary on a frame-by-frame basis.

  • Publication number: 20070025291
    Abstract: Systems and methods for enhancing the capacity of base stations are provided. A base station can operate in a time division duplex mode within a first frequency band. When a second frequency band is acquired for the base station's geographic region, a duplexer can be added to the base station. The base station can then operate in a frequency division duplex mode, where the first frequency band is used for base station downlink transmissions and the second frequency band is used for uplink transmissions.
