Abstract

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.
