FIELD: radio engineering, communication.
SUBSTANCE: method includes determining by a portable device, whether the connection for the near communication with the first terminal is disconnected; and if it is detected that the short-range connection to the first terminal is disconnected, broadcasting a notification message to instruct, at least, one second terminal to establish a short-range connection to the portable device and to instruct, at least, one second terminal to notify about the connection to the server, in order for the server to determine the location of the portable device corresponding to, at least, one second terminal. After broadcasting the notification message and establishing a short-range connection with the nearest second terminals, the second terminals inform the server of the identity of the connected portable device, and the server determines the location of the portable device corresponding to the plurality of the second terminals and thus determines the location information of the portable device.
EFFECT: increasing the determination accuracy.
