The management server 300 may pre-store location information in which a plurality of wireless routers 200a, 200b, 200c, ..., 200m are installed. And through the access information of the user terminals (100a, 100b, 100c, …, 100n) provided from a plurality of wireless routers (200a, 200b, 200c, …, 200m), the user terminals 100a, 100b, 100c, ... , 100n) location and movement path, etc. can be identified. Since various methods are known as a technology for determining the location of a user terminal based on Wi-Fi, detailed descriptions are omitted.

Meanwhile, according to an embodiment, the management server 300 receives GPS information from user terminals 100a, 100b, 100c, ..., 100n connected to a plurality of wireless routers 200a, 200b, 200c, ..., 200m, and GPS Based on the user terminal (100a, 100b, 100c, ..., 100n) it is also possible to determine the location and movement path.
