摘要/Abstract

摘要：

基于宽带无线通信WiMax系统，运用多播轮询技术和 IP语音(VoIP)业务的静默特性，提出了支持VoIP业务的有效的上行调度服务机制和算法。通过理论和仿真分析，在不影响VoIP业务时延特性条件下，新算法能提高系统吞吐量和容纳更多的语音用户。

Abstract:

Making full of multi-polling technique and the silence characteristic of voice over IP（VoIP）service, an new efficient uplink scheduling algorithm is proposed based on broadband wireless access system. via analysis of theory and simulation, the proposed algorithm has superior performance in view of throughput and capacity on the condition of having no influence in the access delay of VoIP service.

Key words: broadband wireless access system, uplink scheduling service, multi-polling, voice over IP services
