Performance analysis of VoIP services on the LTE network

Abstract:

With the arrival of LTE standard it is expected that the mobile voice services paradigm will shift from the circuit switched to fully packet switched mode supporting the VoIP services. VoIP services took quite a bit of time before they were accepted as the main stream telephony service in the fixed networks. To provided VoIP services over the LTE networks with appropriate QoS it is necessary to analyze the performance of such services on the LTE network and optimize the network parameters. This paper analyses the performance of VoIP services on the LTE network using the FD and the SMP packet scheduling techniques. This work identifies and analyzes the features of above LTE packet scheduling techniques to enhance the QoS of VoIP services. An OPNET based simulation model is used to analyse the performance of VoIP services on the LTE network by incorporating G.711 and G.723 speech coders. The work also studied the performance of VoIP services in variable transmission channel conditions.

Video and voice transmission over LTE networks

Abstract:
Video and voice transmission over wireless broadband has become popular and attracted more attention ever since. More and more hand phone owners use their phones to play video and voice over the Internet. Transmitting video and voice in a good quality over the wireless networks is a challenge to service providers. LTE, also known as one of the beyond 3G wireless network technology is designed to have a greater delivery service for multimedia, voice and video applications to end users. However, the QoS provisioning of the voice/video/multimedia in the intricacy wireless network is highly depended on the QoS framework of a network. The QoS framework for LTE network is studied and comparisons among the scheduling algorithms are made in this study. Extensive simulation results showed that the performance of the scheduling algorithms could enhance the video and voice delivery quality.

Hi, Just in case, the great book:
"Voice over LTE (VoLTE)"
by Miikka Poikselkä, Harri Holma, Jukka Hongisto, Juha Kallio, Antti Toskala
Publication Date: March 5, 2012


Description
Describes the technological solutions and standards which will enable the migration of voice and SMS services over to LTE/EPC networks

Main drivers for the introduction of Long Term Evolution of UTRAN (LTE) is to provide far better end user experience for mobile broadband services. However, service providers also need to have a clear strategy of how to offer voice and messaging services for consumers and enterprises. The voice service over LTE is becoming increasingly important when the smartphone penetration is increasing rapidly. Smartphones require both good quality voice and high speed broadband data.

This book provides the exhaustive view to industry-approved technologies and standards behind the Voice over LTE (VoLTE). Whether a decision maker or technology analyst, this book explains a topic of substantial global market interest. It provides a good introduction to the technology and is useful for operators who may be deploying VoLTE, product managers responsible for VoLTE products and those who work in implementation and standardization of related technologies.

* Provides a comprehensive overview of industry-approved technologies and standards, providing vital information for decision makers and those working on the technology
* Written by authors working at the cutting edge of mobile communications technology today, bringing a mix of standards and product background, guaranteeing in-depth practical and standards information
* Covering the technical and practical elements of VoLTE, explaining the various approaches for providing voice services over LTE
