CCL OSA:以CORBA為基礎的開放式服務存取平台

Abstract

Open Service Access (OSA) 是開放式的服務存取平台。該平台提供業者建立與部署兼具彈性與效率的行動服務。OSA可以讓網路的營運業者，透過第三方應用程式與服務的提供者，來增加他們的收入。在OSA的架構下，網路端的功能可以藉由定義不同的Service Capability Features來提供給應用程式使用。由應用程式所實作的服務，則可以透過標準的OSA API來接取Service Capability。本論文設計與發展出以CORBA為基礎的OSA平台。我們說明如何將OSA API中所定義的介面與函式，透過CORBA中的clients，stubs，servants，和skeletons來實作，以及在我們的OSA平台中如何設定CORBA POA和ORB。最後，我們透過初始存取(initial access)的認證流程，來說明CORBA機制如何在我們的OSA實作中運作。

Open Service Access (OSA) is a flexible and efficient approach for mobile service creation and deployment. OSA allows network operators and enterprises to increase revenues via third party applications and service providers. In OSA, network functionality offered to applications is defined by a set of Service Capability Features (SCF). Services can be implemented by applications accessing the Service Capability (SC) through the standardized OSA Application Programming Interface (API). This thesis designs and develops a CORBA-based OSA system. We show how OSA API interfaces and functions can be implemented by CORBA clients, stubs, servants, and skeletons, and how CORBA POA and ORB are set up for our OSA implementation. Then we use the authentication procedure for initial access to illustrate how CORBA mechanism works for our OSA implementation.
