3. Issues With the increase in life expectancy and the number of aging populations, there is a significant interest in wireless healthcare applications that could improve the quality of life of elderly and chronically sick people. 3

4. Motivations Combining the capabilities of WSNs(Wireless Sensor Networks) and the IMS(The IP Multimedia Subsystem) opens the door to a wide range of personalized and adaptive value added services for 3G users. Wireless healthcare is one of the important application areas that can benefit from the combined IMS/WSNs capabilities. 4

5. Goals We focus on this application area and present a case study on the design and implementation of a context-aware IMS wireless healthcare application, that leverages the capabilities of our WSN/IMS integration solution. 5

18. Comments 可發展性 這個架構未來有很多發展的空間，因為它有廣大的擴充 性，透過建置新的 S-CSCF 與其應用伺服器，便能提供 給使用者新的服務項目。 實際問題 因為這屬於醫療上的緊急救護的科技應用，所以應該還 要有其他突發狀況的備援計畫，例如：救護車在前往醫 院途中有緊急事件發生時如何應對。 18
