中文摘要 | IMS為3GPP所訂的一個處理多媒體呼叫的子系統,NGN予以調整後納為其呼叫控制的核心。IMS-based NGN已成為固網業者力求生存的重要法寶,它除了延續既有PSTN/ISDN服務外,還可提供3G、WLAN(Wireless LAN)、xADSL(x Aysmmetric Digital Subscriber Line)與xPON(x Passive Optical Network)等各種接取使用共同服務,達到自然FMC(Fix Mobile Convergence)。在安全與品質的要求下,提供多媒體服務為其服務的主要特色。此外,結合第三者的加值服務開發方式,讓未來的服務呈現更貼近用戶的需求。本文旨在探討滿足上述需求並以IMS為基礎的NGN架構。 |
英文摘要 | The NGN(Next Generation Network) uses the modified 3GPP IMS (IP Multimedia Subsystem) as the main service control component. IMS not only provides the converged and optimized operating networks but also meets the increasing demand for new multimedia services and mobility. One goal of NGN is to replace PSTN/ISDN. Therefore, providing the capabilities in support of the legacy PSTN/ISDN services is also a must. In order to differentiate the services from Internet, NGN shall provide a QoS(Quality of Service) assurance environment for customers, network operators and service providers. Besides the above issues, this paper finally discusses how NGN supports appropriate interconnections to other networks for smooth network evolution. |
