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： 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： 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： 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.
