Publication number: 20170208505Abstract: A method is provided for enforcing quality of service parameters. A gateway receives a request for data usage from a mobile device. The gateway sends, to a controller, inquiry for allowed bit rate. Upon receiving a first bit rate value, the gateway sends, to a charging system, request for quota. In response to receiving the quota, the gateway provides data to the mobile device based on the first bit rate value. The gateway provides data to the mobile device until the quota is exhausted. Once a data usage threshold is reached, the gateway receives, from the controller, a second bit rate value. In response to receiving the second bit rate value, the gateway provides data to the mobile device based on the second bit rate value, until an activation-time is reached. When the activation-time is reached, the gateway resets the allowed bit rate from the second bit rate value to the first bit rate value.Type: ApplicationFiled: January 20, 2016Publication date: July 20, 2017Inventors: Ho Yin Cheuk, Lixia Yan, Violeta Cakulev, Sudhakar Reddy Patil, Raymond So

Publication number: 20160345239Abstract: Systems and methods for data bandwidth optimization are disclosed. A server receives, from a computing device, a request to begin a network data session. Responsive to receiving the request, the server allows the computing device to access network data at a full speed for a grace time period. Upon expiration of the grace time period, the server allows the computing device to access network data at a reduced speed for a monitoring time period. During the monitoring time period, the server monitors the computing device to determine whether the computing device is accessing network data in bursts or streaming data. Based on whether the computing device is accessing network data in bursts or streaming data, the server either allows the computing device to access network data at the full speed for a waiver time period or allows the computing device to access network data at the reduced speed until completion.Type: ApplicationFiled: May 22, 2015Publication date: November 24, 2016Inventors: Barry F.
