This paper presents a remotely manageable electrocardiogram measurement system for managing middleware applications using OSGi and LDAP technologies. The platform incorporates a Device Connection Interface, a Data Transmission System, a Service Management Center, and a Health Care Portal System. In this paper we focus on the health care service manage framework which is intended to simplify the provision of applications and reduce the managing effort. A pilot application for telecardiology is presented and discussed. The system, if successfully operated, will offer better service management framework for large scale of homecare service devices.
