1. A user terminal device for recognizing a user location using sensor-based activity recognition, the user terminal device comprising:

  • a communication interface circuitry (CIC) configured to receive activity information from a mobile device that senses information about at least one of a user state and surrounding environments, and extracts the activity information based on the sensed information, and configured to perform Bluetooth communication and Wi-Fi communication; and

    a processor configured to;

    identify a user location in a user space corresponding to a user activity based on the received activity information,measure a distance between the mobile device and the user terminal device based on signal strength of the Bluetooth communication with the mobile device, andbased on a user and the user terminal device being identified to be in the same location when the measured distance is within a predetermined range, identifying a user terminal location obtained by a Wi-Fi-based positioning system (WPS) as a user location.
