Patent number: 8879409Abstract: A method and system for improving quality of service (QoS) in a wireless network are disclosed. In one embodiment, bearer connection context parameters of each of a plurality of data packets in the wireless network are obtained. Further, general packet radio service tunneling protocol user plane protocol data unit (G-PDU) packets are determined in the plurality of data packets based on first bearer connection context parameters which is a subset of the bearer connection context parameters. Furthermore, the determined G-PDU packets are queued in a non-signaling queue. QoS attributes are then computed for each of the queued G-PDU packets. In addition, priority data is computed for each of the queued G-PDU packets is computed using the computed QoS attributes. Moreover, one or more priority queues are formed based on the computed priority data of each of the queued G-PDU packets for improving QoS in the wireless network.Type: GrantFiled: September 27, 2011Date of Patent: November 4, 2014Assignee: Wipro LimitedInventors: Saptarshi Chaudhuri, Subhodeep Sarkar

Patent number: 8797861Abstract: A system and method for mobile Internet offloading in a wireless communication network are disclosed. In one embodiment, a session is established through an Internet offload gateway (IOGW) with a mobile operator network to establish a communication with a mobile device. A packet coming from the mobile device is received by an intelligent policy manager (IPM) residing in the IOGW during the session. If the received packet is a signaling packet, offload rule flags are generated and operator defined offload policy rules are then enabled. If the received packet is a data packet, it is determined whether the operator defined offload policy rules match with session information associated the data packet. If the operator defined offload policy rules match, the data packet is offloaded to the Internet. If the operator defined offload policy rules do not match, the data packet is sent to a home gateway.Type: GrantFiled: August 25, 2012Date of Patent: August 5, 2014Assignee: Wipro LimitedInventors: Saptarshi Chaudhuri, Subhodeep Sarkar, Soumya Shankar Sardar
