摘要

With the collapse of the conventional telecommunication carrier business model based on distance-based time duration billing system, Internet Protocol (IP) services with monthly flat-rate pricing are rapidly growing. Owing to the accelerating progress in the performance of digital processors and memory, expansion of communication line bandwidth with the use of optical fiber cables, and great advances in mobile terminals as a result of progress in mobile radio telecommunication technologies, business models of communication carriers are dramatically changing to service provider models that can cover sharp drops in unit price per bit using profits from cloud services as well as content and applications. At the same time, this has presented a huge challenge to the global business models of infocommunication system vendors and parts device vendors, which has led to significant changes in technological development and product strategies as described below.
