To achieve interconnection and interoperability among different devices in home network environment, such as TV, PAD, and computer. Several digital home network protocol standards, such as UPnP, Java Intelligent Network Infrastructure (Jini), IGRS, etc, are proposed. But, devices based on these different protocols cannot discover or control each other, so it is very important to achieve interoperability among these devices.

A method of interconnection between IGRS network and UPnP network based on Open Service Gateway Initiative (OSGI) platform is proposed in this paper. A service agent on the OSGI platform is designed. This paper described the system architecture and implement process of this method. The experiment result of this method is also described. It is shown that the Service search and protocol conversion between UPNP and IGRS devices are implemented effectively.
