本文的目的在於整合異質的分散式網路服務，提供了單一的呼叫介面來執行不同標準以及不同架構下所部署的服務，例如JINI Services、Web Services等，並且利用階層式SIP來建構網路平台，用來提供服務mbolity的能力，研究中提出了「Remote Service Invocation；RSI」，來整合異質的服務呼叫，並利用SIP的特性來提供服務mobility的能力，同時支援了非同步呼叫方式，增加了撰寫應用程式時的效能，且透過設計模式的方式來建構系統，以便達到重用性以及可擴充性。本論文的貢獻在於整合分散式環境下的服務呼叫，並提供了服務漫遊以及非同步呼叫。

　　The main purpose of this paper is to integrate varieties of distributed services developed using different existing service middleware and provide single Application Interface (API) to invoke the services under heterogeneous environment such as JINI Services, Web Services etc. We employ SIP to build network platform which supported service mobility. Therefore we propose “Remote Service Invocation (RSI)” to integrate service invocaton APIs. It achieves service mobility capability of utilizing characteristic of SIP and supports asynchronous invocation model to raise system efficiency. Finally we establish system framework using Design pattern for reuse and extension. The major contribution of this paper is to integrate different invocations of distributed heterogeneous services and provide service roaming ability and support asynchronous mode of services’ invocation.
