“…RBP represents the number of PHY RBPs allocated for MBMS video delivery service, F (DL) eMBMS is the fraction of frame symbols allocated for eMBMS, α eMBMS is a fraction of control data required by eMBMS (α eMBMS = 10% [3]), R c f g th% is the average data rate of the c f g system configuration (c f g could be SFN-eMBMS or SC-eMBMS service configuration) required to achieve th% user coverage, and finally, R eMBMS is the service unit data rate: a single eMBMS channel (e.g., 384, 768 or 1536 kbps) [3]. From the number of eMBMS channels the system configuration is able to provide over a given frequency allocation N (DL) RBP , the bandwidth allocation (in kHz) per eMBMS channel is:…”

“…Provisioning of high-quality multimedia services over cellular networks has became a reality as a result of technological maturity reached at both the cellular network and the user equipment (UE) side. Indeed, the requirements for high quality multimedia over cellular are met with the introduction of 3GPP Long Term Evolution (LTE) and LTE-Advanced (LTE-A) [2], [3]. In addition, typical smartphones/tablets available on the market represent powerful handheld computers able to process high-quality compressed multimedia and present it on a large size/resolution screen.…”

SUMMARYMobile video services are becoming a dominant traffic category in emerging fourth generation (4G) cellular networks such as the 3GPP Long-Term Evolution (LTE) and LTE-Advanced (LTE-A). In particular, mobile video unicasting services based on 3GPP Dynamic Adaptive Streaming over HTTP (DASH) and multicasting/broadcasting services based on 3GPP evolved Multimedia Multicast/Broadcast Service (eM-BMS) will require considerable resources for high-quality service delivery with high coverage probability. Faced with the challenge of energy efficient multimedia service provisioning over LTE/LTE-A, in this paper, we present simple analytical tools for evaluation of average service data rates, bandwidth and energy-consumption requirements applicable for different multimedia delivery services and LTE/LTE-A radio access network (RAN) configurations. Moreover, we introduce and evaluate novel energy and bandwidth performance measures defined per unit of service. As a result, we are able to compare the efficiency of different multimedia service delivery configurations over LTE/LTE-A. In particular, in this paper, as a running example we focus on eMBMS and compare the Energy of Service (EoS) of the two macro-cellular LTE/LTE-A configurations recently proposed in 3GPP: i) a single frequency network eMBMS (SFN-eMBMS), and ii) a single-cell eMBMS (SC-eMBMS). Furthermore, we extend this analysis to eMBMS provisioning over Heterogeneous Networks (HetNets) environment. However, the methodology presented is general and targets light-weight system design and comparison of bandwidth/energy costs of different LTE/LTE-A multimedia service delivery configurations. key words: eMBMS, energy efficiency, video multicast, LTE/LTE-A

“…Según el estudio realizado en [2], para el año 2016 el tráfico de datos móviles llegará a más 10.8 Exabytes por mes, del cual el 70% será generado por flujos de video. Es por tanto que las redes móviles están al borde de una tercera fase de evolución en la cual el tráfico de datos móviles será dominado principalmente por contenidos de video y que se requerirán nuevas formas de optimizar la red para evitar la saturación de la misma [3]. La estimación del incremento de este tipo de tráfico es uno de los principales impulsores para la adopción de los nuevos estándares de banda ancha móvil LTE (Long Term Evolution) y LTE-Advanced (LTE-A) [3].…”

SUMMARYThe next step beyond third generation mobile networks is the Third Generation Partnership Project standard, named Long Term Evolution. A key feature of Long Term Evolution is the enhancement of multimedia broadcast and multicast services (MBMS), where the same content is transmitted to multiple users located in a specific service area. To support efficient download and streaming delivery, the Third Generation Partnership Project included an application layer forward error correction (AL‐FEC) technique based on the systematic fountain Raptor code, in the MBMS standard. To achieve protection against packet losses, Raptor codes introduce redundant packets to the transmission, that is, the forward error correction overhead. In this work, we investigate the application of AL‐FEC over MBMS streaming services. We consider the benefits of AL‐FEC for a continuous multimedia stream transmission to multiple users and we examine how the amount of forward error correction redundancy can be adjusted under different packet loss conditions. For this purpose, we present a variety of realistic simulation scenarios for the application of AL‐FEC and furthermore we provide an in‐depth analysis of Raptor codes performance introducing valuable suggestions to achieve efficient use of Raptor codes.
