摘要: A Next Generation Network (NGN) has been developed in Taiwan, where IP Multimedia Subsystem (IMS) plays an important role to offer IP-based multimedia services. Such NGN/IMS networks have also been deployed worldwide. However, details of commercial-grade NGN service implementations are seldom reported in public. In this paper, we show how existing video phone service can be enhanced through Chunghwa Telecom's NGN/IMS. Specifically, we illustrate three examples including Multimedia on Demand (MOD) TV, Multimedia Ringback Tone (MRBT), and Easy Go (EzGo). We also measure the delay times for accessing these services. The measurements indicate that performance for these IMS-based services is satisfactory. Copyright (c) 2010 John Wiley & Sons, Ltd.
