Recently, many researches focus on Ubiquitous Network which comprised various networks for effective service provision. In particular, OSGi proposed by OSGi Alliance is preferred for core infrastructure to establish Ubiquitous Network as it supports integration and inter-operation among various service environments, and dynamic configuration of services. However, OSGi is limited to be used only within local service framework, since OSGi specification does not have any considerations for inter-operations between internal and external services. Thus, in this paper we propose JARSIO(JAva Remote Service Invocation for OSGi) framework which enables the inter-operations of dynamic internal OSGi services and other external services. The proposed framework is based on the TCP/IP protocol, and provides effective mechanisms for the inter-operations of the services.
