Abstract

Distributed architecture offers many advantages compared to centralized architecture in terms of providing multimedia services. However, as a trade-off, distributed architecture requires that peers contribute a portion of their bandwidth and computational capacity to maintain the mutual overlay interconnection. This requirement develops into a serious problem for mobile users and wireless infrastructure, as the radio resource in this network is tremendously expensive, based on 3gpp , and is one of the reasons why distributed architecture has not been widely applied in next-generation (4G) networks. It is also the main reason why multimedia services such as video conference have to rely on a costly centralized architecture built over an expensive media resource function controllers via the Internet protocol (IP) multimedia subsystem (IMS). This research work proposes a new distributed architecture utilizing intelligence and extra capacity, currently available on LTE and WiMAX base stations to reduce the required bit rates that each peer has to provide in order to maintain the overlay network. This reduction saves valuable radio resources and allows a distributed architecture to provide video conferencing services on 4G networks, with all the advantages of a distributed architecture such as flexibility, scalability, smaller delay, and lower cost. In addition, this can be implemented with a minimum modification of the standardized IMS platform and the 4G infrastructure, thereby saving the operators and service providers from excessive investments. A prototype has been built to prove the feasibility of the proposed architecture and evaluate its performances. The results show that our proposed distributed video conferencing service can actually reduce the average bandwidth required for data and signaling messages at wireless mobile terminals while maintaining the main operations of a video conference session.

Intra-stream traffic differentiation and resource allocation for video teleconferencing in LTE systems
liangping ma

2013 IEEE 15th International Workshop on Multimedia Signal Processing (MMSP), 2013

This paper considers a downlink LTE system where a basestation (eNodeB) is serving video traffic (generated possibly due to video teleconferencing applications) to many users in a cell. The video traffic is separated into multiple sub-streams (logical channels) based on the coding structure or priority of video packets. The objective is to maximize video quality by servicing appropriate video sub-streams and users while taking into account the resource constrained wireless channel. It is shown that one can obtain significant gains in video quality by determining the quality of service (QoS) parameters on a per sub-stream basis, rather than in 'user-based' approach where all the sub-streams are lumped into one single stream. Motivated by video teleconferencing applications, we provide simulation results for the case where video traffic is separated into logical channels based on a Hierarchical-P encoding structure. Furthermore, we demonstrate the gains in video quality that can be obtained by allocating resources across logical channels. With the exploding growth in mobile video traffic expected to happen in 4G systems, this study suggests potential benefits of a logical channel based approach as compared to conventional user-based schemes.

Enhanced video phone services for NGN/IMS
Yi-bing Lin

Wireless Communications and Mobile Computing, 2010

A Next Generation Network (NGN) has been developed in Taiwan, where IP Multimedia Subsystem (IMS) plays an important role to offer IP-based multimedia services. Such NGN/IMS networks have also been deployed worldwide. However, details of commercial-grade NGN service implementations are seldom reported in public. In this paper, we show how existing video phone service can be enhanced through Chunghwa Telecom's NGN/IMS. Specifically, we illustrate three examples including Multimedia on Demand (MOD) TV, Multimedia Ringback Tone (MRBT), and Easy Go (EzGo). We also measure the delay times for accessing these services. The measurements indicate that performance for these IMS-based services is satisfactory.

High Quality of Service Video Conferencing over IMS
VERA SURYANI

International Journal of Information and Education Technology, 2016

IMS is an evolving definition of an architecture that solves the continuing demands and frustrations of users and enterprises. IMS is a whole new way to deliver multimedia services (voice, video, data, etc.) regardless of the device (mobile phone, landline phone, cable, Internet, etc.) and will change the way all of us relate to our increasingly digital world. Real-time applications such as voice and video have a great deal of demand over IMS network. The QoS is the major concern for real-time application such as voice and video. In order to fulfill the users demand, it is necessary to improve the QoS. In this work, we implement IntServ and DiffServ with MPLS which can have great potential in improving the QoS scheme in IMS for video conferencing. We evaluate the performance of QoS for video conferencing over that mechanism perform with IMS. The performance is evaluated based on some QoS parameters such as end-to-end delay, packet loss and jitter. In order to investigate the performance of QoS scheme in IMS, we analyze the simulation results. The investigation shows that proper adaptation of QoS provides qualitative transmission of video conferencing in wireline. Finally on the basis of the simulation results, we study the QoS performance and propose difference schemes to enhance the QoS performance in IMS based on the QoS parameters.  Index Terms-IP multimedia subsystem (IMS), multi-protocol label switching (MPLS), video conferencing (VC), quality of service (QoS).

QoS Performance Evaluation of Video Conferencing over LTE
IMAM HOSSEN

2012

Mobile data usage has been on the rise in relation to the streaming media such as video conferencing and online multimedia gaming. As a result, Long-Term Evolution (LTE) has earned a rapid rise in popularity during the past few years. The aim of this master’s thesis is to analyze the quality of service (QoS) performance and its effects when video is streamed over a GBR (Guaranteed bit rate) and non-GBR bearers over LTE. Using OPNET (Optimized Network Engineering Tool), the performance can be simulated having Downlink (DL) and Uplink (UL) scenarios for video conferencing including web traffic. Further we also measured the performance of packet End-to-End (E2E) delay, packet loss and packet delay variation (PDV). This thesis work is an empirical work, which can be followed up by further research propositions.

Beyond 3G video mobile conversational services: An overview of 3G-324M based messaging and streaming
Andrea Basso

2004

3G-324M is a 3 rd Generation Partnership Project (3GPP) umbrella standard for wireless video communications, which was created to satisfy the stringent requirements of real-time, low-delay interactive conversational video services. However it is, in practice, employed today in 3G networks to enable also a variety of multimedia services including messaging and streaming. The unification of this variety of services under the same umbrella standard has significance for the design of the supporting architectures and the applications that run such services. In this paper we will discuss the current limitations of 3G-324M in supporting streaming and messaging services and propose a set of requirements that imply some extensions and clarifications of the standard to better support them.

An Evaluation of Architectures for IMS Based Video Conferencing
Khoem Sambath

The IP Multimedia Subsystem is an architectural framework for delivering multimedia services over an Internet Protocol (IP) network. Originally, it was specified for wireless networks, but has since evolved to incorporate fixed line access as well. It forms part of a Next Generation Network (NGN) which is defined as a packet-based network where the service functionality is independent of the underlying transport technologies. This allows new converged services to be implemented on top of an existing packet switched network.

Architecture and Protocol to Optimize Videoconference in Wireless Networks
José Luis García Navas

Wireless Communications and Mobile Computing

In the past years, videoconferencing (VC) has become an essential means of communications. VC allows people to communicate face to face regardless of their location, and it can be used for different purposes such as business meetings, medical assistance, commercial meetings, and military operations. There are a lot of factors in real-time video transmission that can affect to the quality of service (QoS) and the quality of experience (QoE). The application that is used (Adobe Connect, Cisco Webex, and Skype), the internet connection, or the network used for the communication can affect to the QoE. Users want communication to be as good as possible in terms of QoE. In this paper, we propose an architecture for videoconferencing that provides better quality of experience than other existing applications such as Adobe Connect, Cisco Webex, and Skype. We will test how these three applications work in terms of bandwidth, packets per second, and delay using WiFi and 3G/4G connections. Fin...

2011 15th International Conference on Intelligence in Next Generation Networks, 2011

This paper proposes a new service architecture based on the interconnectivity between Subscriber Units (SUs) running on WiMAX network participating in an Application Layer Multicasting-based distributed multimedia conference. The novelty of the proposal is that it replaces the standard centralized architecture of IMS-based conference in order to utilize the intelligence and computational capacity of WiMAX Base stations. Thank to a distributed architecture, the expensive Media Resource Function Controller (MRFC) and Media Resource Function Processor (MRFP) can be completely omitted in this proposal. Experimental results show that the proposed architecture outperforms the previous system. Afterward, a prototype has been built to measure and prove the advanced performance of the proposed architecture.
