Long Term Evolution (LTE) is a 3GPP standard for wireless transmission systems. It is also the first 3GPP wireless standard full IP-based. Due to its possibility to reach very high throughput (e.g. 100 Mbps in downlink), an efficient end-to-end QoS treatment is needed in order to guarantee a good QoS perceived by end user (QoE). Voice service delivered by LTE systems is Voice over IP (VoIP) service, with no QoS-aware mechanism. LTE provides a unique and native QoS-aware mechanism for end-to-end service delivering based on EPS bearer and QCI. Since efficient end-to-end QoS management of VOLTE should treat different aspects, this paper analyze the influence of voice codecs on end-to-end VoLTE performance. Different voice codecs are considered in different scenarios simulated using OPNET Modeler software tool. Final comparison among them is provided.

Abstract
Long Term Evolution (LTE) is a 3GPP standard for wireless transmission systems. It is also the first 3GPP wireless standard full IP-based. Due to its possibility to reach very high throughput (e.g. 100 Mbps in downlink), an efficient end-to-end QoS treatment is needed in order to guarantee a good QoS perceived by end user (QoE). Voice service delivered by LTE systems is Voice over IP (VoIP) service, with no QoS-aware mechanism. LTE provides a unique and native QoS-aware mechanism for end-to-end service delivering based on EPS bearer and QCI. Since efficient end-to-end QoS management of VOLTE should treat different aspects, this paper analyze the influence of voice codecs on end-to-end VoLTE performance. Different voice codecs are considered in different scenarios simulated using OPNET Modeler software tool. Final comparison among them is provided.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
