    摘要: IP多媒體子系統(IP Multimedia Subsystem;IMS),是一種嶄新的多媒體應用服務平台。它能夠滿足使用者更新鮮、更多樣化的多媒體需求,而且它解決了行動通訊與固網的結合,因此IMS被認為是下一世代網路(Next Generation Networking;NGN)的核心。 對於未來的應用服務現在還沒有一個明確之說明顯示它會以何種形式呈現,但是可以確定的是,未來之應用服務不會是單一的,而會是一種多重應用服務結合而成。另外,除了新穎的應用服務出現外,既有的應用服務也不能抹滅,而是使之更豐富化。關於應用服務的接取技術,在未來無論使用何種技術,對使用者來說操作應用服務的方式依舊,且不受限制。 本論文主要探討在IMS上佈建應用服務,以U化(Ubiquitous)車輛派遣系統為例來呈現,讓派遣系統跳脫傳統注入新想法,加入狀態服務(Presence service)、定位服務(Location service)、有多樣的叫車方式與緊急呼叫。藉由這個實作,我們希望有越來越多的IMS服務可以更豐富人們的生活。 IP Multimedia Subsystem(IMS) is a brand-new platform designed for multimedia services and applications. IMS lets subscribers enjoy novel services and meets the variety of requirements from them. Moreover, IMS deals with problems that come from merging the existing access networks including wireless and fixed ones. Therefore, IMS is considered to be the core part of Next Generation Networking(NGN). Up to now, the characteristics of applications and services in the NGN are defined unclearly. Nevertheless, what we can make sure is that any application or service deployed in the future will comes with plenty of functionalities which each offered by a single application or service nowadays. In addition, except bringing in novel applications, legacy services should not be threw away. Contrarily, we shall make them more abundantly. When speaking to network accessing technologies, it is important that subscribers can keep their operation knowledge and skills they have learned from existing ones to operate new ones with pleasantness. In this paper, we introduce the development and deployment of an application based on IMS platform, which is named as “ubiquitous vehicle assignment system”. Many functionalities are integrated into the vehicle assignment system, for example, presence service, location service, multiple way to ask vehicle, emergency call, etc. By this implementation, we hope that there will be more and more services base on the IMS platform as successors to benefit human’s daily lift.
