Due to key developments in the telecommunications industry, such as Voice over WiFi and 3G network integration, together with increasingly aggressive competition and rapid technology changes, service providers are faced with the challenge of creating a new, service-centric management model that provides for the creation of new services and assures superior service quality. This unique resource offers a practical view of the service model concept and discusses the management issues that you need to understand in order to implement an effective management solution for operating in today's competitive environment. Explaining how such a model can be integrated in your organization's operations flow, the book clearly explains the tight relationships among business, service, technology, and operations. You learn how to drastically improve the service quality of important advanced and emerging mobile services, solve service assurance and operations problems related to dual mode mobile phone service, and design a large scale operations system for supporting next generation wireless applications. This practical book guides you in migrating from traditional network-centric operations to service- based operations that are geared for today's known applications, and can be adapted for future service growth.
