Abstract: A method and apparatus provide an indoor travel path based on a beacon. In an embodiment, the apparatus extracts, as a target beacon, at least one beacon device corresponding to at least one destination and also extracts, as an intermediate beacon, one or more beacon devices intervening between the target beacon and a user's terminal device. Then the apparatus establishes a link connecting the target beacon and the intermediate beacon and, based on the established link, calculates one or more paths configured to start from a current location of the terminal device, to pass through the intermediate beacon, and to arrive at the target beacon. Further, the apparatus selects a travel path having the minimum number of link hops from among the calculated paths and offers it to the terminal device.

Abstract: A radio fingerprint device implements a radio fingerprint map construction and location tracking method. In this method, the radio fingerprint device receives, from a manager terminal device, radio environment information varying for a predetermined time at a specific referential position in a particular indoor area so as to create a radio fingerprint map. Then the radio fingerprint device extracts a periodic pattern from the received radio environment information, and stores, in the radio fingerprint map, the extracted periodic pattern as a radio fingerprint feature of the specific referential position.

The method of expanding beacon service coverage using the terminal may include receiving a beacon signal transmitted from a beacon device, measuring signal strength of the beacon signal to determine whether to perform a beacon function, and transmitting the beacon signal within a certain service coverage when the terminal determines to perform the beacon function.

Abstract: A user's terminal device and a service management server can provide specific service content associated with a registered beacon service to a user. In an embodiment, the terminal device registers at least one beacon service at a user's request and sends information about the registered beacon service to the service management server. Then the terminal device receives first beacon identification information corresponding to the registered beacon service from the service management server and stores the first beacon identification information. Further, when a beacon signal containing second beacon identification information is received from a beacon device, the terminal device compares the second beacon identification information with the first beacon identification information. If both of identification information are identical with each other, the terminal device offers service content corresponding to the second identification information.
