Osgi-Based Dynamic Service Management Method for Context-Aware Systems
First Claim
1. An OSGi-based dynamic service management method for context-aware system, characterized in that a service manager comprising a service bundle, a service bundle activator, a service installer, and a service factory is added to an OSGi service framework so as to allow a dynamic service management in the context-aware system, whereby management is achieved in service unit in a bundle, and an object of the service manager is implemented as a remote object so as to remotely manage the object of the service manager, whereby a remote access is possible and various environment modeling is possible.

Abstract
An OSGi-based dynamic service management method for context-aware system is provided. By adding a service bundle for service implementation to an OSGi framework, a service lifecycle is separately managed. For this purpose, the service bundle has several service implementations, and a service factory object is generated as many as the service implementations. The lifecycle of the service is managed. The service factory object installs and uninstalls the service. Accordingly, even when various sensors and devices are newly added to the context-aware system, a corresponding service can be installed and uninstalled at any time, thereby providing a dynamic management.
