对于新一代的无线网络，宽带无线系统的融合将成为一个重要的技术难题。近年来，尽管一些研究人员已经提出了几种技术方案用来增强第二代媒体访问控制协议（MAC ），但这些设计主要针对的是数字信息。针对实时宽带信源给出一个了更好的集中控制访问技术，这项技术通过实现信息源的统计复用，并根据不同用户的服务质量需求来对无线终端进行组合，使之形成一个固定的有线宽带网络。同时这项技术将轮询方式与随机接入方式整合在一起，基站中的数据包调度程序负责动态地选择最高传输需求吞吐量的接入方式。对上述方法进行了性能测定，并估算了相关的参数。

For the new generation of wireless networks,the convergence of wireless systems with broadband services is becoming an important technical issue.In recent years,several schemes for enhancing second-generation media access control(MAC)protocols have been proposed,which,however,mainly focus on digital information.In this paper,an enhanced centrally controlled access technique for real-time broadband sources is presented.It enables full integration of wireless terminals into fixed wired broadband networks by realizing the statistical multiplexing of sources and depending on the user's requirements of quality-of-service. Furthermore,the technique combines random access with polling,and the packet scheduler running at the base station dynamically selects the access method with the highest throughput for transmission of capacity requests. The performance of the method is tested,and the relevant parameters are calculated.
