    Abstract: A method and an apparatus for maintaining a quality of service (QoS) for a multi-media packet data service in a transport network is provided. The method comprises determining a first packet loss indication for a first flow of QoS traffic packets. The method further comprises determining a second packet loss indication for a second flow of QoS traffic packets, wherein the determination of the first packet loss indication for the first flow of QoS traffic packets is independent from the determination of the second packet loss indication for the second flow of QoS traffic packets. The method further comprises determining whether to drop the first flow of QoS traffic packets based on the first packet loss indication or to drop the second flow of QoS traffic packets based on the second packet loss indication. By using per-flow independent packet loss statistics to determine whether that flow should be dropped and gradually dropping such QoS flows having the most impact on a desired QoS performance, a reduced number of QoS flows may be dropped to recover a data transport network from congestion.

    Abstract: For applications with very small data activities, connection of a UE to a wireless network for sending or receiving such small data traffic increments via conventional connection set-up processes is quite inefficient in terms of spectral resource utilization. The invention provides a new connectionless methodology for transmission of such small data increments between a UE and a serving eNB. In particular, the invention methodology contemplates identifying a set of preamble sequences among the pool of preamble sequences provided for access requests from a UE to an eNB via the Random Access Channel as corresponding to a request from the UE for access to transmit an increment of data smaller than a predetermined threshold data size. When a UE has data traffic to transmit of a size smaller than the predetermined threshold size, it selects one of the preamble sequences in the identified set and sends an access request, using the selected preamble sequence, to a serving eNB via the Random Access Channel. Upon receipt of the access request from the UE, the eNB determines an appropriate RF resource for the data increment sought to be transmitted by the UE, based on the use of the selected preamble sequence sent by the UE, and schedules an uplink connection for the transmission of that data increment by the UE.

    Abstract: A wireless communication system (20) includes backhaul congestion control. Whenever congestion is detected on the backhaul, a flow control message sets a window size to a reduced window size to reduce or eliminate packet drops and to facilitate alleviating the congestion condition. A disclosed example includes detecting backhaul congestion and responsively reducing an available backhaul receiver buffer space factor used for setting the window size for a subsequent backhaul transmission. In a disclosed example, the buffer space factor is gradually increased back toward an actual available buffer space as the congestion status improves.

    Abstract: In order to help music players without sufficient musical knowledge to adapt original music pieces but still keep the original style, the present invention provides an interactive system and the accompanying method for creating music by substituting audio tracks. The interactive system includes a database of musical elements that comprises tonality, tempo, beat, timbre, texture, chord, and pitch, a database of music that contains multiple original music pieces, and a processor. As a result, players without strong knowledge in music theories can create adapted a music piece that matches the style of the original one.

    Abstract: Method, device, and non-transitory computer-readable medium detecting a gathering of objects based on stereo vision are disclosed, and the method comprises steps of obtaining current and prior images and a corresponding depth map; extracting foreground pixels corresponding to detection objects from the current and prior images, and projecting the foreground pixels onto a ground surface to acquire a foreground projection image including foreground projection blocks; conducting, based on image feature differences of the foreground pixels between the current and prior images, projection onto the ground surface to acquire moving foreground projection blocks; utilizing the moving foreground projection blocks to erode the foreground projection blocks to obtain still foreground projection blocks; and determining, based on the still foreground projection blocks, whether the gathering of objects exists.
