Abstract
In this paper, we analyze the voice communication over Long Term Evolution (LTE) network which is transmitted using a voice over internet protocol (VoIP), as in LTE the core network is purely packet switched, designed for high data throughput. Similarly to legacy circuit-switched network, serving the largest number of users performing simultaneous VoIP calls, and ensuring their satisfaction will be the main objective for LTE operators willing to introduce voice over LTE service. To simulate the impact of scheduling strategies in the VoIP capacity, we use the Open Wireless Network Simulator (OpenWNS). With the obtained results, we show the VoIP capacity bottleneck. We also recommend the best strategies to improve the VoIP capacity.
