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。
In recent years, the use of QoS (Quality of Service) mechanism to achieve differentiated service delivery in mobile communication networks has been a hot research topic. End-to-end QoS includes identification of non-access stratum users and services, consistent delivery of QoS across bearers, and correct implementation of access-layer QoS. Based on the data traffic transmission mechanism in EDGE network, the QoS mapping of 3GPP QoS framework in GERAN A / Gb mode and UTRAN Iu mode of UMTS network is comprehensively studied. An optimized end-to-end QoS parameter mapping table Based on this table, the feasibility of QoS parameter optimization and the consistency of parameter mapping are verified in the real EDGE network. The experimental results show that using different transmission strategies based on different business characteristics can improve business perception.
