The third wireless network generation (3G) aims to provide fast Internet access with quality of service (QoS) guarantees, especially to multimedia applications. UMTS (Universal Mobile Telecommunication System) is a kind of 3G networks. To provide QoS, the network must use an efficient admission control mechanism. This mechanism needs to prioritize network access to critical classes of applications. This work proposes an UMTS admission control mechanism, called CAC-RD (Call Admission Controlbased on Reservation and Diagnosis). It is based on network diagnosis and on channel reservation for handovers. These techniques are associated with new calls blocking when the network reaches utilization thresholds. CAC-RD is a tool that prioritises handovers and conversational applications. The main CAC-RD goals are the handovers blocking reduction and the acceptable performance levels guarantee. Simulation results show that the CAC-RD channel reservation and the diagnosis techniques associated with the intrinsic network signal power control effectively reduces blockings while guarantying performance levels. Due to computational resource limits, simulations cannot answer related to admission control in big networks with thousands of users. This work presents a method to extrapolate scientific questions like CAC's behavior with thousands of users and many

“…Given the number of different technologies, the possibility exists to extend mobile TV reception to handheld devices-personal TVs, PDAs, even mobile phones. This can further be enhanced by using 3G networks such as General Packet Radio Service (GPRS) [21] and Universal Mobile Telecommunications System (UMTS) [22] to provide the user with converged services via an interaction channel (usually a network allowing the user to interact with the broadcast/network operator) while on the move [23].…”

The subject of the future of the interactive Television medium has become a topic of great interest to the academic and industrial communities particularly since in the recent years there has been a dramatic increase in the pace of innovation of convergence of digital TV systems and services. The purpose of this paper is to provide a brief overview of what we know as digital TV converged services, to present and categorise the digital Television middleware technologies that contributed to it, and to present possible future trends and directions. A new Television era of converged wireless and mobile content delivery, user-authored content, multimodal interaction, intelligent personalisation, smart space awareness, and 3D content sensations is foreseen, creating ambient and immersive experiences.

Among the factors, which can affect the quality of service of the four different levels of the traffic classes differentiated by their sensitivity to the delay tolerance, signaling ranks on the top. There is significant signaling messaging activity in UMTS among core network elements, and between SGSN and UTRAN that needs to be characterized so that its impact on the application architecture could be determined, and appropriate hardware and service software architectures to support signaling could be developed. Signaling affects mobility management, session management, call setup, and teardown times, etc. thus affecting the QoS of applications. In this paper we first examine the resulting signaling load on a core and a radio access networks for a given traffic penetration in the packet domain by considering a signaling procedure "Attach" and then analytically compute the throughput and the latencies for other basic signaling procedures such as Detach, and the PDP context activation in addition to attach by considering a platform which can act as a signaling server for the RNC, the SGSN, and the GGSN.
