LTE-Advanced中的QOS参数映射的研究

摘要

QoS参数映射提供了一种机制,使得下层能够从上层的信息中获得相关的QoS信息,从而保障整个传愉的服务质量.随着LTE-A系统的不断更新演进,在满足系统架构的QoS决定、传递或映射系统信息的功能方面,QoS参数映射起着越来越重要的作用.文章根据LTE-A中的QoS参数映射架构,分析了该架构中各组成部分的功能和作用,对具体参数的映射过程和映射规则做出了详细的说明.%Mapping of QoS parameters provides a mechanism for lower layers to know the service QoS information of the upper layer so that transmission quality is guaranteed. As LTE-A continues to be evaluated, mapping of QoS parameters is becoming more important in satisfying the QoS decision of the system architecture and transforming or mapping systems information. This paper analyzes the architecture for mapping QoS parameters in LTE-A. It examines the function of each part of the architecture' s framework and specifies the mapping process and rules for specific parameters.
