摘要

在本文中，我们提出了不同的IEEE 802.16e上行通道访问机制，可用于在静默期后激活扩展实时轮询服务(ertPS) IP语音(VoIP)连接。通过仿真比较了不同恢复机制的性能，特别是上行链路延迟。除了对上行VoIP延迟进行研究外，还研究了不同机制下上行资源的使用情况。在我们的研究中，我们发现使用快速反馈通道或多播轮询是最有希望有效恢复ertPS VoIP的方法。

Uplink VoIP Delays in IEEE 802.16e Using Different ertPS Resumption Mechanisms

In this paper, we present different IEEE 802.16e uplink channel access mechanisms that can be used to activate extended real-time polling service (ertPS) voice over IP (VoIP) connections after a silence period. The performance, especially uplink delay, of different resumption mechanisms is compared with each other using simulations. In addition to uplink VoIP delay, we study the uplink resource usage with different mechanisms. In our studies, we have found that using the fast feedback channel or multicast polling are the most promising approaches for efficient ertPS VoIP resumption.
