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： The present invention provides a method and an apparatus of wireless communication with at least one wireless unit. The method includes detecting an indication of error in a plurality of traffic frames to control transmit power between at least a first and second forward link based on the indication of error. The method further includes receiving a plurality of consecutive traffic frames over at least two reverse links from a wireless unit to select a frame in soft handoff. To control transmit power, for example, a controller may perform reverse link error detection after frame selection. The controller detects a frame error to boost the transmit power, substantially correcting a link imbalance situation. In this way, by controlling transmit power in a spread spectrum wireless communication system to reduce call drops, a call drop rate may be significantly decreased while increasing capacity of radio frequency transmission.

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 handover between wireless telecommunications networks of different technology types, an air interface is set up between a first node 4 included in a network of a first technology type and a second node 10 included in a network of a second different technology type. Signaling messaging, in accordance with the second technology type, is related to handover of a mobile terminal from the network of the first technology type to the network of the second technology type. The signaling messaging is encapsulated in a container for transmission over the signaling interface. An identifier is associated with the container to indicate that it encapsulates the signaling messaging. When the identifier is detected at the first node, the container is sent over the interface to the second node. In one method in accordance with the invention, the first technology type is WiMAX and the identifier is a special service flow identifier. This may be detected at an Access Services Network Gateway (ASN GW), for example. A method in accordance with the invention thus permits the use of logical radio channels for encapsulating inter-technology signaling.
