Book Synopsis System Engineering for IMS Networks by : Arun Handa

Download or read book System Engineering for IMS Networks written by Arun Handa. This book was released on 2009-03-12. Available in PDF, EPUB and Kindle. Book excerpt: The IMS is the foundation architecture for the next generation of mobile phones, wireless-enabled PDAs, PCs, and the like. IMS delivers multimedia content (audio, video, text, etc.) over all types of networks. For network engineers/administrators and telecommunications engineers it will be essential to not only understand IMS architecture, but to also be able to apply it at every stage of the network design process. This book will contain pragmatic information on how to engineer IMS networks as well as an applications-oriented approach for the engineering and networking professionals responsible for making IMS function in the real world. - Describes the convergence of wireless IMS (IP Multimedia Subsystem) with other networks, including wireline and cable - Discusses building interfaces for end users and IMS applications servers - Explores network management issues with IMS

Book Synopsis Voice over LTE by : André Pérez

Download or read book Voice over LTE written by André Pérez. This book was released on 2013-09-03. Available in PDF, EPUB and Kindle. Book excerpt: Voice over LTE (Long Term Evolution) presents the mechanisms put in place in 4G mobile networks for the transportation of IP packets containing voice data and telephone signaling, as well as the technologies used to provide a telephone service in the IMS (IP Multimedia Sub-system) network. Despite the difficulty connected to the handover of the 4G network to the 2G/3G network, a telephone communication will not be established on the 4G network. This book analyzes the technologies that have been put in place, such as CSFB (Circuit Service FallBack), an interim solution that enables a mobile connected to the 4G network to receive an alert transmitted by the 2G/3G network. The book also goes on to develop the SIP (Session Information Protocol) on which the telephone signaling transferred by the 4G network is based, the IMS network that provides the service and defines the routing, the SRVCC (Single Radio Voice Call Continuity) mechanism that maintains communication and the TAS (Telephony Application Server) that supplies supplementary services. Contents 1. The EPS Network. 2. The LTE Interface. 3. The CSFB Function. 4. SIP and SDP Protocols. 5. The IMS Network. 6. Telephone Services. 7. The SRVCC Function. About the Authors André Perez is a consultant and teacher in networks and telecommunications. He works with industrialists and operators regarding architecture studies and leads training on the 4G and IMS networks for NEXCOM.

Book Synopsis IMS Application Developer's Handbook by : Rogier Noldus

Download or read book IMS Application Developer's Handbook written by Rogier Noldus. This book was released on 2011-08-23. Available in PDF, EPUB and Kindle. Book excerpt: IMS Application Developer Handbook will give a hands-on view of exactly what needs to be done by IMS application developers to write an application and take it "live" on an operator's network. It will offer practical guidance on building innovative applications using the features and capabilities of the IMS network, show how the rapidly changing development environment is impacting on the business models employed in the industry and how existing network solutions can be moved towards IMS. The book will also elaborate on how IMS applies basic VoIP principles and techniques to realise a true multi-access, multimedia network. The Handbook demonstrates how the IMS architecture and protocols are applied to multimedia services from a "hands-on" perspective, ensuring that developers know how to use the IMS most effectively for their chosen application. Clear, concise and comprehensive view of the IMS and Rich Communication Suite (RCS) for developers. Written by established experts in the IMS services layer, who have been involved in many customer projects for the implementation of fixed mobile converged IMS network and service. Covers potential service and operator scenarios for the IMS architecture; it is significantly more than merely a description of the IMS standards.

Book Synopsis Performance Optimization of IP Multimedia Subsystem by : Mlindi Mashologu

Download or read book Performance Optimization of IP Multimedia Subsystem written by Mlindi Mashologu. This book was released on 2010-06-18. Available in PDF, EPUB and Kindle. Book excerpt: The IP Multimedia Subsystem (IMS) is the basic network architecture for Next Generation Networks (NGN) which is intended to bridge the divide between the traditional circuit switched and packet switched networks, thereby providing a single network capable of providing all service offerings. IMS is based on the IP infrastructure and it enables the convergence of data, speech and video on the same network platform. The IMS forms the basis of Fixed Mobile Convergence (FMC), where fixed-line operators are striving to provide mobile access and mobile operators are trying to provide fixed access. This is done to provide both services to a customer in a single device. The IMS is based on Session Initiation Protocol (SIP), which is a text-based protocol. The IMS will generally create additional signaling traffic in the IP based networks, so there is a need to take necessary precautions to minimize the signaling overload. This research is based on how the performance of the IMS can be improved by optimization of SIP as well as IMS elements. An analysis and characterization of the signaling traffic generated by IMS has been performed and how the signaling traffic can be reduced by the compression of SIP using the Burrows Wheeler Transform (BWT) has been explored. The queuing models of the IMS have been formulated and the mathematical approach has been used to find the impact of implementing the Hyper-Threading technology on the IMS Elements.
