摘　　要：在移动通信网内采用业务质量(QoS,Quality of Service)机制实现差异化的业务传输是近年的研究热点。端到端QoS包括非接入层用户和业务的识别、不同承载间QoS的一致性传递和接入层QoS的正确执行。这里以EDGE网络中数据业务传送机制为基础,全面研究了3GPP的QoS框架在UMTS网络的GERAN A/Gb模式和UTRAN Iu模式中的QoS映射,给出一个经过优化的端到端QoS参数映射表,并基于该表,在真实的EDGE网络中验证了QoS参数优化的可行性和参数映射的一致性。实验结果表明,根据不同业务的特点采用差异化的传输策略可以提升业务的感知。The adoption of QoS mechanism for achieving differentiated service transmission now becomes a hotspot in mobile communication network.The end-to-end QoS includes the identification of users and services in non-access layer,the consistent transfer among different bearers and the correct transfer in access layer.Based on the packet transport mechanism in EDGE network,an in-depth study on QoS paramaters translation and mapping of 3GPP QoS framework in UMTS GERAN A / Gb mode and UTRAN Iu mode is done.A optimized parameters mapping table is given and the impact on the service performance is verified in a real EDGE network.Experiment results show that the adoption of differential transport strategy and optimized parameters in accordance with different service characteristics could improve the perception and capacity of the network.
