Patent number: 7864802Abstract: A method and system, are provided for dynamically allocating channel resources in a wireless network. The wireless network may be a multi-rate network having a base station controller that adapts wireless channel rates associated with a communication session based on a TCP sending rate associated with a sending device. The base station controller includes a scheduler and optimization engine that probes the wireless network to gather TCP parameters, such as round trip times, etc. The optimization engine utilizes a long-term sending rate to generate a subset of channel rates from available channel rates associated with the wireless network. The scheduler engine utilizes the instantaneous sending rate to adapt the wireless channel rate by selecting a channel rate from the subset of channel rates.Type: GrantFiled: August 17, 2006Date of Patent: January 4, 2011Assignee: Sprint Communications Company L.P.Inventors: Majid Ghaderi Dehkordi, Ashwin Sridharan, Hui Zang

Patent number: 7733777Abstract: A media, method, and system, are provided for dynamically allocating channel resources to multiple TCP sessions in a wireless network. The wireless network may be a multi-rate network having a base station controller that adapts wireless channel rates associated with a communication session based on a preemption probability associated with a high-rate channel. The base station controller includes a scheduler and optimization engine that probes the wireless network to gather TCP parameters, such as round trip times, etc. The optimization engine utilizes a long-term sending rate to generate a subset of channel rates from available channel rates associated with the wireless network. The scheduler engine utilizes the instantaneous sending rate to adapt the wireless channel rate by selecting a channel rate from the subset of channel rates.Type: GrantFiled: June 8, 2007Date of Patent: June 8, 2010Assignee: Sprint Communications Company L.P.Inventors: Ashwin Sridharan, Majid Ghaderi, Hui Zang
