QoS参数映射是异构网络中动态保证业务QoS的关键技术。本文研究了一种保证用户满意的端到端服务质量的方法，重点研究了级联中各层之间的服务质量映射问题。由于参数的动态映射，保证了用户和网络之间的一致性。在本文中，我们提出了一种新的跨层QoS映射机制的基础上，多元线性回归。该机制实现了QoS参数在用户层和传输层之间的垂直映射。因此，在网络之间建立QoS连接，以确保业务的端到端QoS。仿真结果表明，该机制在不降低平均吞吐量的情况下，可以大大提高用户的满意度。
QoS parameter mapping is a key technology with respect to guaranteeing QoS of business in heterogeneous networks dynamically. This paper studies a method for guarantee necessary End-to-End QoS for user satisfaction, focusing on the problem of quality of service (QoS) mapping between layers in a cascade. Due to the dynamic mapping of parameters, the consistency between user and network is guaranteed. In this paper, we proposed a novel cross-layer QoS mapping mechanism on the basis of a multiple linear regression. The mechanism realizes the vertical mapping of QoS parameters between user-level and transport-level. Hence the QoS connection is constructed between networks to ensure the end-to-end QoS of business. The simulation results show that our mechanism can greatly improve the satisfaction of users without reducing the mean throughput.
