Abstract
The present invention relates to a heath care system having proximity-based neighbor device wake-up and automatic user identification function, a method for automatic logging of user's daily activity history, and a method for managing a user activity pattern, and the system comprises: a health or wellness service unit; and an user terminal. The health or wellness service unit transmits a wake-up signal for changing a state of the user terminal from a sleep state into a wake-up state, a low frequency (LF) signal for identifying a physical distance and direction between the health or wellness service unit and the user terminal, and a measured biological signal of a measuring object. The user terminal receives the biological signal, the wake-up signal, and the LF signal through bidirectional wireless communication with the health or wellness service unit, and transmits a terminal identification (ID) and a received signal strength indication (RSSI) corresponding to the received LF signal.
