WCDMA(W ideband Code D ivision Mu ltip le Access)系统的一个重大挑战,就是在保证服务质量的前提下,承载各种不同类型的业务。为此,在对WCDMA网络的QoS(Quality of Service)和QoE(Quality of End-user Experience)管理、网络监测和优化等问题进行研究的基础上,分析了几种网络配置以及实时业务向不同QoS等级映射的问题,给出了优先选择方法区分服务模型。结果表明,该模型系统能以最符合成本效益的方法承受QoS实时服务,灵活地处理区分服务业务,QoS测试结果验证了预期优先选择方法的优越性。运用优先选择方法后,网络的频谱利用率达到32%;区分服务模型使网络的资源使用能力提高了23%。
A major challenge for the WCDMA (Widband Code Division Multiple Access) system is to host a wide range of different types of services while maintaining quality of service. Therefore, based on the research of Quality of Service (QoE) and QoE (Quality of End-user Experience) management and network monitoring and optimization of WCDMA networks, several network configurations and the impact of real-time services on different QoS Level mapping problem, given the priority selection method to distinguish service model. The results show that the model system can bear the QoS real-time service in the most cost-effective way and handle the differentiated services flexibly. The QoS test results verify the superiority of the expected prior selection method. With the prior selection method, the spectrum utilization rate of the network reaches 32%; and the service differentiation model improves the resource utilization capability of the network by 23%.
