20110267951 | Systems and Methods For Prioritization of Data For Intelligent Discard in a Communication Network - Systems and methods for optimizing system performance of capacity and spectrum constrained, multiple-access communication systems by selectively discarding packets are provided. The systems and methods provided herein can drive changes in the communication system using control responses. One such control responses includes the optimal discard (also referred to herein as “intelligent discard”) of network packets under capacity constrained conditions. The systems and methods prioritize packets and make discard decisions based upon the prioritization. Some embodiments provide an interactive response by selectively discarding packets to enhance perceived and actual system throughput, other embodiments provide a reactive response by selectively discarding data packets based on their relative impact to service quality to mitigate oversubscription, others provide a proactive response by discarding packets based on predicted oversubscription, and others provide a combination thereof. | 11-03-2011 |

20120008499 | SYSTEMS AND METHODS FOR PRIORITIZING AND SCHEDULING PACKETS IN A COMMUNICATION NETWORK - Systems and methods provide a weight-based scheduling system that incorporates end-user application awareness and can be used with scheduling groups that contain data streams from heterogeneous applications. Individual data queues within a scheduling group can be created based on application class, specific application, individual data streams or some combination thereof. Application information and Application Factors (AF) are used to modify scheduler weights to differentiate between data streams assigned to a scheduling group. Dynamic AF settings may adjust relative importance of user applications to maximize user Quality of Experience (QoE) in response to recurring network patterns, one-time events, application characteristics, protocol characteristics, device characteristics, service level agreements, or combinations thereof. Scheduling weights may be dynamic and incorporate the notions of “duration neglect” and “recency effect” in an end-user's perception of video quality in order to optimally manage video traffic during periods of congestion. | 01-12-2012 |
20120013748 | SYSTEMS AND METHODS FOR PRIORITIZATION OF DATA FOR INTELLIGENT DISCARD IN A COMMUNICATION NETWORK - Capacity and spectrum constrained, multiple-access communication systems optimize performance by selectively discarding packets. Changes in the communication systems may be driven using control responses. Control responses include intelligent discard of network packets under capacity constrained conditions. Packets are prioritized and discard decisions are made based on the prioritization. Various embodiments provide an interactive response by selectively discarding packets to enhance perceived and actual system throughput, provide a reactive response by selectively discarding data packets based on their relative impact to service quality to mitigate oversubscription, provide a proactive response by discarding packets based on predicted oversubscription, or provide a combination thereof. Packets may be prioritized for discard using correlations between discards and bandwidth reduction and quality degradation. The quality degradation for video packets may be measured objectively. | 01-19-2012 |

20120140730 | ADVANCED TECHNOLOGY FRAME STRUCTURE WITH BACKWARD COMPATABILITY - An advanced technology frame structure is described herein. The advanced technology frame structure can enhance a first technology frame structure in dimensions of time, frequency, or a combination of time and frequency. A second technology frame structure time division multiplexes second technology subframes with the first technology downlink and uplink subframes. The first technology downlink subframe can be divided into a first technology downlink subframe and one or more second technology downlink subframes. Similarly, the first technology uplink subframe can be divided into a first uplink subframe and one or more second technology uplink subframes. These principles can be expanded upon and can be applied in many communication systems. | 06-07-2012 |

Individual data queues within a scheduling group can be created based on application class, specific application, individual data streams or some combination thereof. Application information and Application Factors (AF) are used to modify scheduler weights to differentiate between data streams assigned to a scheduling group. One embodiment adjusts the relative importance of different user applications using dynamic AF settings to maximize user Quality of Experience (QoE) in response to recurring network patterns, one-time events, or both. One embodiment maximizes user QoE for video applications by dynamically managing scheduling weights is provided that incorporates the notions of “duration neglect” and “recency effect” in an end-user's perception of video quality in order to optimally manage video traffic during periods of congestion. | 12-27-2012 |
20130142055 | SYSTEMS AND METHODS FOR PRESERVING APPLICATION IDENTIFICATION INFORMATION ON HANDOVER IN A COMMUNICATION NETWORK - Systems and methods preserve application identification information on handover in a communication network. End user quality of experience is improved by determining applications associated with communications to and from the end user. The applications may include application classes and specific applications. The application information is used to schedule packets such that the end user quality of experience is improved for that application. When the end user is handed over between wireless access nodes, the access nodes transfer application information so that the improved end user quality of experience is maintained. | 06-06-2013 |
