摘要
超3G的移动通信系统是一种全口的系统，它融合了因特网和移动通信的优点。BRAIN(基于IP的宽带无线接入网)的发展就是要把基于HIPERLAN／2(high performance radiolocal area network type 2)的本地宽带无线接入系统和多个宽覆盖的移动通信系统结合起来，使用户无论是在热点地区还是在移动中都能实现基于口服务的无缝覆盖。能够提供端到端的QoS是在系统设计中的关键环节，因此在系统的应用中，网络以及无线接入层中都必须支持QoS。文中介绍了QoS系统的结构，包括终端结构和基于IP的接入网的结构。
Mobile radio systems beyond the third generation will evolve into allIP systems, integrating Internet and mobile system advantages. The BRAIN project is developing a system architecture which combines local coverage broadband radio access systems based on HIPERLAN/2 with several widercoverage mobile radio systems, enabling full coverage of seamless IPbased services for users in hot spot areas and on the move. Endtoend QoS provision is one of the major challenges in the design of such a system and must be supported by the application, network, and wireless access layers. This article proposes a QoS system architecture, including the terminal architecture, and the IPbased access network.
