20080212501 | Half Duplex Frequency Division Duplex Scheduling - A method, computer program, and a wireless system for scheduling half duplex frequency division duplex bursts includes populating a burst frame having an uplink sub-frame and a downlink sub-frame with one or more block pairs, each block pair including an uplink block and a down link block. Populating the burst frame includes identifying a largest unscheduled block pair, and appending one of the uplink block and the downlink block of the identified block pair to a shortest sub-frame string. Populating the burst frame also includes appending the other of the uplink block and the downlink block to a diagonally opposed sub-frame string. The method also includes determining if a conflict exists between the uplink block and the downlink block for each scheduled block pair. | 09-04-2008 |
20100198943 | SYSTEM AND METHOD FOR PROGRESSIVE DOWNLOAD USING SURPLUS NETWORK CAPACITY - Systems and methods for providing the progressive download of media content using techniques that preferentially identify and use periods of surplus network capacity to maintain the content delivery. A buffer of a receiving system is maintained and pre-filled with enough content to bridge playback intervals where a network is unable to deliver content as fast as it is played out. Content delivery does not impact other users' applications and use of the network and its resources since content is only sent when surplus network capacity exists in the network. When no surplus network capacity is available, a user requesting content may be given the option to continue the delivery in the background so that the content may be played at a later time. The user may then resume their playback experience once the content has been completely delivered using surplus network capacity as it becomes available. | 08-05-2010 |
20100274871 | SYSTEM AND METHOD FOR CONGESTION DETECTION IN AN ADAPTIVE FILE DELIVERY SYSTEM - An adaptive file delivery system and method transmits a data file, such as an audio-video file, over a network or collection of networks in segments, each segment transmitted during a different time period. Each time period has a transmission portion to transmit its associated file segment and a wait portion in which no further interaction with the network occurs regarding the transmitted segment. In some implementations, the duration of the transmission portion of each time period is sufficient to reach a steady-state throughput condition, which allows the traffic load status of the network or networks to be determined from rate measurements of file segment transmissions. The duration of the wait portion of each time period is at least long enough to limit the average rate of file segment transmission to adapt to network traffic load variations and avoid network congestion. Various techniques for measuring congestion are described. | 10-28-2010 |
20100274872 | SYSTEM AND METHOD FOR FLOW CONTROL IN AN ADAPTIVE FILE DELIVERY SYSTEM - An adaptive file delivery system and method transmits a data file, such as an audio-video file, over a network or collection of networks in segments, each segment transmitted during a different time period. Each time period has a transmission portion to transmit its associated file segment and a wait portion in which no further interaction with the network occurs regarding the transmitted segment. In some implementations, the duration of the transmission portion of each time period is sufficient to reach a steady-state throughput condition, which allows the traffic load status of the network or networks to be determined from rate measurements of file segment transmissions.

20110029664 | SYSTEM AND METHOD FOR PEAK FLOW DETECTION IN A COMMUNICATION NETWORK - An adaptive file delivery system and method transmits a data file, such as an audio-video file, over a network or collection of networks in segments, each segment transmitted during a different time period. Each time period has a transmission portion to transmit its associated file segment and a wait portion in which no further interaction with the network occurs regarding the transmitted segment. In some implementations, the duration of the transmission portion of each time period is sufficient to reach a steady-state throughput condition, which allows the traffic load status of the network or networks to be determined from rate measurements of file segment transmissions. A peak flow determination is made to assure that the delivery of file segments does not cause network congestion. The system has spurious peak rejection to avoid the false detection of network congestion. | 02-03-2011 |

The first data type may relate to either voice data communications or another high priority data type, and the second data type may relate to a media content file type. | 06-02-2011 |
20120106383 | SYSTEM AND METHOD FOR AUTONOMOUS DISCOVERY OF PEAK CHANNEL CAPACITY IN A WIRELESS COMMUNICATION NETWORK - A wireless device includes a data structure that relates peak channel capacity to the quality of the wireless communication link. The wireless communication link quality forms an index to indicate the expected peak channel capacity for that particular quality value of the wireless communication link. The wireless device uses the data storage structure to determine an expected data transfer throughput based on the quality of the wireless communication link. A transfer rate lower than expected may indicate congestion in the core network or the RAN. In this case, the network may slow the data delivery from the data source or temporarily suspend delivery. Conversely, low data throughput may be the result of a poor quality wireless communication link. If the data structure indicates that the data throughput corresponds to the expected throughput for the quality value of the wireless communication link, the system need not take any steps to reduce congestion. | 05-03-2012 |
