Dynamic control of air interface throughput |
摘要 |
A system, method, and network node for dynamically controlling throughput over an air interface between a mobile terminal and a radio telecommunication system. A Gateway GPRS Service Node (GGSN) receives a plurality of traffic flows for the mobile terminal and uses a Deep Packet Inspection (DPI) module to determine a target delay class for each traffic flow. The GGSN signals the target delay class of each traffic flow to a Radio Network Controller (RNC) utilizing per-packet marking within a single radio access bearer (RAB). The RNC defines a separate virtual queue for each delay class on a per-RAB basis, and instructs a Node B serving the mobile terminal to do the same. The Node B services the queues according to packet transmission delays associated with each queue. A flow control mechanism in the Node B sets a packet queue length for each queue to optimize transmission performance.
