摘要： 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.

摘要： A method and an apparatus for reducing packet loss for a packet data service during congestion in a transport network are provided. The method comprises measuring a packet loss rate over a time period in one or more flows of data traffic packets associated with the packet data service to determine whether the one or more flows of data traffic packets are experiencing a variation in a desired traffic performance level at a particular time duration during the congestion in the time period. The method further comprises triggering a request to reduce a flow rate of at least one of the one or more flows of data traffic packets based on the packet loss rate if the at least one of the one or more flows of data traffic packets experiences the variation in the desired traffic performance level. By using a distributed transport congestion control, for example, only such Best Effort data traffic packet flows that generate bursty traffic at a specific moment of congestion sense the congestion and thus trigger an associated rate reduction action. However, other flows that do not experience the congestion may not be affected.

摘要： 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.

摘要： A method for gracefully degrading packet data voice quality in a wireless network includes monitoring and evaluating data transfer conditions on the network. This may be done on a network-wide level, or for access terminals individually. For the evaluation, data transfer conditions are compared to criteria that indicate a relative quality level. Based on the evaluation, a variable number of the voice data packets addressed to the access terminals are eliminated prior to transmission over the airlink. If conditions are optimal, no data packets are eliminated. If not, one or more packets may be eliminated periodically (e.g., 1 data packet out of every five) until conditions change. The access terminals compensate for any eliminated packets. In this manner, packet data voice quality is gracefully degraded for temporarily reducing voice traffic on the network when conditions are poor, avoiding the need for dropped calls or the like.
摘要翻译：一种在无线网络中适度降级分组数据语音质量的方法包括监测和评估网络上的数据传输条件。这可以在网络范围内进行，也可以单独进行接入终端。对于评估，将数据传输条件与指示相对质量水平的标准进行比较。基于该评估，在通过空中链路传输之前，消除了寻址到接入终端的可变数量的语音数据分组。如果条件最佳，则不会消除任何数据包。如果不是，则可以周期性地消除一个或多个分组（例如，每5个中1个数据分组），直到条件改变为止。接入终端补偿任何消除的分组。以这种方式，当条件差时，分组数据语音质量被适度地降级以临时降低网络上的语音流量，避免了掉话等的需要。

摘要： A wireless communication system (20) allows communications between a mobile station (22) and a wireless network (24) over combined physical traffic channels (44, 46). In a disclosed example, a mobile station (22) has multiple wireless access terminals (40, 42) for transmitting different portions of a communication over multiple physical traffic channels (44, 46). In a disclosed example, each wireless access terminal (40, 42) utilizes one of the channels (44, 46). A known multilink PPP protocol facilitates splitting a communication into portions to be communicated over the combined physical traffic channels (44, 46) and then recombined at the mobile station (22) or an appropriate portion of the network (24). With a disclosed example, the achievable throughput using combined physical traffic channels (44, 46) approaches the aggregate or sum of the individual channel throughput capacities.

摘要： 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.
