Signaling for multimedia conferencing in 4G: the case of integrated 3G/MANETs

Fourth-generation wireless systems are composed of coexisting and cooperating legacy and new networks. Mobile ad hoc networks are examples of new networks. They have several attractive characteristics and are gaining more and more momentum. Their integration with legacy third-generation networks is now being contemplated. Multimedia conferencing is the basis of a wealth of applications, including video conferences, multiparty games, and distance learning. Signaling is the central nerve of multimedia conferencing. It establishes, modifies, and tears down multimedia conferencing applications. This article is devoted to the signaling aspects of multimedia conferencing in 4G and focuses on the specific case of integrated 3G/MANETs. It reviews the standard 3G architecture and the emerging architectures for MANETs. This review shows that none of them is suitable for integrated 3G/MANETs. We propose a new architecture based on application-level clusters and conference gateways. We have implemented a prototype using the session initiation protocol (SIP) technology.

The 3G-324M protocol for conversational video telephony

As mobile operators worldwide migrate to third-generation (3G) networks, conversational video-telephony services are becoming a key differentiator between new 3G offerings and existing 2G/2.5G services. Although it's possible to have limited video-based services - such as a multimedia messaging service - that deliver pictures and video clips over 2.5G services, these are delay-insensitive applications that could run over a packet-based wireless network like general packet radio service (GPRS) or code division multiple access (CDMA)'s 1XRTT. For delay-sensitive applications such as conversational video telephony, present 3G packet bearers are inadequate, and the Third Generation Partnership Project (3GPP; http://www.3gpp.org) mandates using the 3G bandwidth-guaranteed circuit-switched bearer and the 3G-324M system. The 3G-324M system is a derivative of the International Telecommunication Union (ITU) H.324 protocol standard for low-bitrate multimedia communication, which ITU-T developed for the public switched telephone network (PSTN). This article describes the 3G-324M system, which has been adopted by both 3GPP and 3GPP2 (htpp://www.3gpp2.org), as well as its H.324 roots.

Resource management and quality of service in third generationwireless networks

The third generation networks and services present opportunities to offer multimedia applications and services that meet end-to-end quality of service requirements. The key parts of the standards are already in place, and limited 3G services have already been turned on. While the evolution to 3G occurs, many operators will implement 2.5G interim solutions for a good period of time. We discuss the various evolution scenarios from the present 2G networks to 3G networks. Then we present the UMTS QoS architecture and its requirements, followed by a discussion on QoS in 3G air interfaces, radio access network, and core network

Interactive cellular and cordless video telephony: State-of-the-art system design principles and expected performance

Second-generation (2G) mobile radio standards have not been designed with video communications in mind, although the employment of error-resilient, constant-bit-rate proprietary video codecs over these systems is realistic. The third-generation (3G) systems are capable of providing higher rates and better communications integrity in support of video applications. This paper advocates the employment of burst-by-burst adaptive transceivers, which are capable of accommodating the time-variant channel quality fluctuation of wireless channels. This paper is concluded with a range of performance figures and system design guidelines for wireless systems.
