Abstract—Hypertension and arrhythmia are chronic diseases, which can be effectively prevented and controlled only if the physi- ological parameters of the patient are constantly monitored, along with the full support of the health education and professional med- ical care. In this paper, a role-based intelligent mobile care system with alert mechanism in chronic care environment is proposed and implemented. The roles in our system include patients, physicians, nurses, and healthcare providers. Each of the roles represents a person that uses a mobile device such as a mobile phone to com- municate with the server setup in the care center such that he or she can go around without restrictions. For commercial mo- bile phones with Bluetooth communication capability attached to chronic patients, we have developed physiological signal recogni- tion algorithms that were implemented and built-in in the mobile phone without affecting its original communication functions. It is thus possible to integrate several front-end mobile care devices with Bluetooth communication capability to extract patients’ var- ious physiological parameters [such as blood pressure, pulse, satu- ration of haemoglobin (SpO2), and electrocardiogram (ECG)], to monitor multiple physiological signals without space limit, and to upload important or abnormal physiological information to health- care center for storage and analysis or transmit the information to physicians and healthcare providers for further processing. Thus, the physiological signal extraction devices only have to deal with signal extraction and wireless transmission. Since they do not have to do signal processing, their form factor can be further reduced to reach the goal of microminiaturization and power saving. An alert management mechanism has been included in back-end health- care center to initiate various strategies for automatic emergency alerts after receiving emergency messages or after automatically recognizing emergency messages. Within the time intervals in sys- tem setting, according to the medical history of a specific patient, our prototype system can inform various healthcare providers in
