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 Andr? Perez is a consultant and teacher in networks and telecommunications.

The UK government has committed to reducing the nation’s carbon emissions by 80% by 2050. Buildings currently use almost half of the UK’s generated energy and they are now the focus of an unprecedented drive to cut energy use in our homes, offices, schools, libraries – in fact in almost every building, public or private. Delivering Sustainable Buildings: an industry insider’s view offers peer-to-peer insights and advice from a leading practitioner in this field and brings together in one book an overview of the main issues to consider when creating energy-efficient and sustainable buildings. A resource to dip into for practical advice, which is both highly readable and also backed up by in-depth technical knowledge, giving the important points to note and common pitfalls to avoid. Based on observations of an author with hands-on experience of dealing with the various elements of the building services engineering industry, the book gives a unique insight into the particular challenges faced by designers, project managers, contractors and installers working to deliver lower carbon and sustainable building projects and operation. There is a lot of guidance on sustainable buildings available from reputable sources including BRE, CIBSE, B&ES, ECA and BSRIA. This book is different in that it speaks directly to contractors and practitioners, with practical messages dealing with real on-site challenges, offering practical advice based on experience. Many contractors are now faced with a business choice of offering services related to issues of the energy hierarchy, minimising energy use, providing good building automation and controls and then looking further at microgeneration/renewables. Here they must decide what technologies might be suitable for their businesses, as well as considering what level of training is required before they or their employees can start to work with these technologies. Delivering Sustainable Buildings: an industry insider’s view will help specialist contractors and facilities managers understand sustainable buildings at the strategic level (legislation, finance, training) and then to offer practical advice on various aspects of sustainable buildings (water use, energy-efficient building services, commissioning and keeping the building maintained to optimum performance) to their clients.

Dementia is increasingly and widely recognised as a serious health and social challenge, in the developed world as well as in the developing world. The need therefore to design and implement dementia care services of high quality is becoming more and more vital, particularly given the likelihood of ever increasing demand in a world, which likely sees resources at best remaining at current levels. Designing and Delivering Dementia Services describes current developments in the design and configuration of dementia services. It offers an informative and detailed overview of what constitutes high quality care, considering the circumstances patients and carers may find themselves in. For dementia to get the priority it deserves, a number of factors are important and the book charts the invaluable contributions of various Alzheimer's Associations and Societies: this provides a focus on dementia strategies and plans at national levels: the book reports on the state of affairs regarding such strategies and provides a unique insight into the process of how one of these was developed and implemented. Recognising the need to prove that service developments lead to a higher quality of care, increased productivity and increased efficiency, the book links the resulting picture to service-based research methodologies, with an emphasis on the strengths and limitations of that research. Contributions from 17 countries on 4 continents give an overview of the state of affairs across the world, paying attention to successful – and less successful – initiatives to improve dementia care. The book furthermore provides pragmatic approaches to ensure planning becomes reality, highlights the need for structured workforce development, education and training and describes the opportunities afforded by assistive technology. This book is of prime informative and practical value given that pressures on dementia services are projected to mount across the world against a backdrop of limited resources and expertise. Designing and Delivering Dementia Services Defines the problems involved in meeting an increasing demand for dementia care services in a poorer world Maps initiatives and developments in the design and configuration of these services in a variety of international settings Analyses these developments against the background of political and health economic circumstances Provides a road map of where health services should go in response to this growing challenge. The first book to define, analyse and map initiatives for dementia care services in a time of increasing demand and decreasing resources, this book is essential reading for commissioners, senior clinicians and service planners in health and social care. It will also be of interest to academic researchers involved in qualitative services research as well as quantitative health economic research, health and social care managers and those involved in workforce planning and development.
