    • Methods and network nodes for dynamically controlling throughput over an air interface between a mobile terminal and a radio telecommunication system, are disclosed. A Gateway GPRS Service Node (GGSN) (12) receives a plurality of traffic flows for the mobile terminal and uses a Deep Packet Inspection (DPI) module (11) to determine (41) a target delay class for each traffic flow. The GGSN signals (23) the target delay class of each traffic flow to a Radio Network Controller (RNC) (16) utilizing per-packet marking within a single radio access bearer (RAB). The RNC defines (24) a separate virtual queue for each delay class on a per-RAB basis, and instructs (25) a Node B (17) serving the mobile terminal to do the same. The Node B (17) services the queues according to packet transmission delays associated with each queue. A flow control mechanism sets a packet queue length for each queue to optimize transmission performance.
    • 公开了用于动态地控制移动终端和无线电通信系统之间的空中接口的吞吐量的方法和网络节点。 网关GPRS服务节点(GGSN)(12)为移动终端接收多个业务流,并使用深度分组检测(DPI)模块(11)确定(41)每个业务流的目标延迟类别。 GGSN信号(23)使用单个无线电接入承载(RAB)内的每个分组标记,向无线电网络控制器(RNC)(16)传送每个业务流的目标延迟类别。 RNC在每个RAB的基础上为每个延迟类定义(24)单独的虚拟队列,并指示(25)为移动终端服务的节点B(17)进行相同操作。 节点B(17)根据与每个队列相关联的分组传输延迟来服务队列。 流控制机制为每个队列设置分组队列长度,以优化传输性能。
