基于IP网络的宽带无线接入（BRAIN）项目旨在研究一种结合不同无线接入网络技术的系统。我们提出了管理端到端QoS的机制，包括传输路径中的移动端系统和基于IP的无线接入网（即BRAIN接入网，BAN）。这包括移动性对QoS问题的可能影响。在移动环境中支持QoS很难实现，因为与固定网络相比，无线链路存在潜在的切换（水平和垂直）和错误率模式。为了解决这个问题，需要QoS信令和自适应机制。我们建议在BRAIN QoS框架和BRAIN ENd Terminal Architecture （BRENTA）的基础上进行构建，BRENTA提供了从用户和应用程序的角度端到端管理QoS的终端系统功能。我们还展示了接纳控制如何嵌入到整个场景中，并为QoS的端到端协商起草了几个协议变体，这些协议变体集成了本地资源管理和源自用户QoS需求的自适应路径策略。
The BRAIN (broadband radio access for IP based networks) project has been proposed to study a system that combines different wireless access network technologies. We present mechanisms to manage end-to-end QoS, including mobile end-systems and IP based wireless access networks (i.e. the BRAIN access network, BAN) in the transmission path. This includes the possible impact of mobility on QoS issues. Supporting QoS in mobile environments is hard to achieve because of potential handovers (horizontal and vertical) and error rate patterns of wireless links in contrast to fixed networks. To solve this issue, QoS signalling and adaptation mechanisms are required. We propose to build upon the BRAIN QoS framework and the BRain ENd Terminal Architecture (BRENTA), which provides the end-system functionality to manage QoS end-to-end from the users and applications point of view. We also show how admission control is embedded in the overall scenario and draft several protocol variants for an end-to-end negotiation of QoS that integrates local resource management and adaptation path strategies derived from users' QoS requirements.
