Abstract :
Long Term Evolution (LTE) is the first fully IPbased 3GPP standard for wireless transmission system. Due to innovative features it is able to offer very high throughput (e.g. 100 Mbps in downlink) to end user. For this reason Mobile Network Operators (MNO) need to adopt efficient end-to-end QoS approach in order to improve service quality perceived by end user. This should be adopted especially in case of delay sensitive services carried out over LTE networks, like VoIP over LTE (VoLTE). Transmission conditions and network impairments are key negative factors that can affect service delivery and network management activities. This research paper analyzes the influence of link utilization and network congestion on end-to-end basis VoLTE performance. Different scenarios are simulated using OPNET Modeler software tool in a good way. Finally comparison among them is provided.
