Claim 0:
1. A method of providing location tracking service based on situational awareness information of a location tracking device, the method comprising:
detecting the situational awareness information measured by a situation analysis engine of the location tracking device, the situational awareness information comprising a heart rate, a body temperature, a movement status of a user, and situation information acknowledged by sensors configured to receive signals in the vicinity of the location tracking device;
determining a situation or a surrounding situation of the user of the location tracking device based on the situational awareness information measured by the situation analysis engine of the location tracking device;
selecting a location tracking module to be used for a location tracking in the location tracking device based on a power consumption criterion and a precision criterion of the location tracking module according to the determined situation based on whether the user is in an emergency state or a non-emergency state and the user's location is indoors or outdoors, the location tracking module comprising at least one of SIGFOX, Bluetooth Low Energy (BLE), Global Positioning Service (GPS), Wireless Fidelity (WI-FI), and Low Power Wide Area Network (UWB);
detecting location data of the user of the location tracking device using the selected location tracking module;
selecting a communication method for transmitting the detected situational awareness information and location data based on determining if the user of the location tracking device is in the emergency state, if a response message is available to confirm that a signal sent from the location tracking device is received to a network server when the user is in the non-emergency state, and if an interference recovery operation is available in a state in which the response message is available, the communication method comprising at least one of SIGFOX, LoRa (Long Range), NB_IoT (Narrow Band Internet of Things), LTE CAT.M1 (Long Term Evolution Category 1 Machine Type Communication), and 5G (5 Generation); and
transmitting the situational awareness information and location data to the network server using the selected communication method.
