Discusses typical regulatory rules and the legal and administrative framework for regulation, and looks at regulatory strategies, market structures and approaches to price control. The book includes a number of case studies which show how regulators engage with such topical issues as interconnection and loop unbundling, and also features technical coverage of both numbering and number portability. Finally, it looks at new products and services such as virtual network operators, intelligent networks, radio spectrum and next generation networks, and considers the impact these might have on the future of regulation.
