Patent number: 10624153Abstract: 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.Type: GrantFiled: November 14, 2018Date of Patent: April 14, 2020Assignee: Time Warner Cable Enterprises LLCInventors: Umamaheswar A.

Patent number: 10028193Abstract: 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.Type: GrantFiled: March 29, 2016Date of Patent: July 17, 2018Assignee: Time Warner Cable Enterprises LLCInventors: Rajesh Gangadhar, Praveen Srivastava, Sourabh Gupta

Patent number: 9232364Abstract: 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.Type: GrantFiled: May 18, 2009Date of Patent: January 5, 2016Assignee: Nextel Communications, Inc.Inventors: Zheng Cai, Feng Huang, Rajesh Gangadhar

Patent number: 8098748Abstract: 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.Type: GrantFiled: November 13, 2007Date of Patent: January 17, 2012Assignee: Clearwire IP Holdings, LLCInventors: Nagi A.
