摘要
对上述技术的QoS框架进行了简要比较。无线资源管理(RRM)技术用于全球微波接入互操作性(WiMAX),可以提供4G无线网络所承诺的许多服务和功能。例如支持高数据速率、广覆盖区域的多媒体业务,以及具有安全性和QoS (Quality of Service)支持的全ip。QoS支持包括包调度和带宽分配策略。该方案有效地提高了性能和资源利用率,同时又具有公平性和实用性。QoS支持标准定义的所有流量类,并根据流量特性和业务需求采用不同的技术动态改变带宽分配。
A Quality of Service Based Resource Allocation in Wireless Communication Networks
A brief comparison of the QoS framework of the aforementioned technologies is provided. Radio Resource Management (RRM) techniques used in the Worldwide Interoperability for Microwave Access (WiMAX) can provide for many of the services and features promised by 4G wireless networks. Such as supporting multimedia services with high data rates, and wide coverage area, as well as all-IP with security and Quality of Service (QoS) support. QoS Support includes packet scheduling and bandwidth allocation strategies. The proposed solution efficiently enhances performance and utilizes resources, while being fair, practical. In this QoS support to all traffic classes defined by the standard, and it dynamically changes the bandwidth allocation based on the traffic characteristics and service demands using different techniques.
