MMS has evolved from the huge popularity of the SMS text service for GSM networks. It is a departure from the transport mechanism used for SMS (which is based on the GSM signalling channels) to the use of IP to transport messages within the MMS network. To this end MMS has similarities with Internet email and standard IETF protocols. As with any new technology it is difficult to accurately predict the position within the next 5 years, although based on previous experience with WAP and SMS it would be fair to say that these protocols will increase in usage over the next 5 years and become legacy for a further 5 years following which, users will migrate onto the next wave of messaging. Significant revenue growth and data usage is expected to be driven by consumer usage of MMS. But MMS technology offers more than just a broadening of message content. With MMS, it is not only possible to send your multimedia messages from one phone to another, but also from phone to email, and vice versa. This feature dramatically increases the possibilities of mobile communication, both for private and corporate use. Multimedia messaging will reshape the landscape of mobile communication, making it more personal, more versatile, and more expressive than ever before. MMS:  Is the first book to address how MMS (and the use of IP to transport messages) will affect existing infrastructure and business models Covers the fundamental changes to mail and billing systems Includes future recommendations, such as interoperability and evolution Presents an overview of the MMS technology components  Drawing on the authors hands-on experience in the implementation of MMS technology (developing, billing and delivering services) at BT, this innovative book will appeal to engineering managers, network operators, market analysts, business decision makers, content providers and operator organizations.

Mathematical Programs with Equilibrium Constraints

<p>This book provides a solid foundation and an extensive study for Mathematical Programs with Equilibrium Constraints (MPEC). It begins with the description of many source problems arising from engineering and economics that are amenable to treatment by the MPEC methodology. Error bounds and parametric analysis are the main tools to establish a theory of exact penalization, a set of MPEC constraint qualifications and the first-order and second-order optimality conditions. The book also describes several iterative algorithms such as a penalty based interior point algorithm, an implicit programming algorithm and a piecewise sequential quadratic programming algorithm for MPECs. Results in the book are expected to have significant impacts in such disciplines as engineering design, economics and game equilibria, and transportation planning, within all of which MPEC has a central role to play in the modeling of many practical problems.</p>
