System and method for positioning mobile device by using bluetooth signal
First Claim
1. A system for positioning a mobile device by using a Bluetooth signal, in which the mobile device receives the Bluetooth signal, which is periodically transmitted by a beacon, to determine the location of the mobile device, the system comprising:
- a strong signal beacon configured to periodically transmit a first Bluetooth signal having a first identification number representing the strong signal beacon, with a relatively strong intensity;
a plurality of weak signal beacons arranged within a Bluetooth signal range of the strong signal beacon and each configured to transmit a second Bluetooth signal having a second identification number representing each of the plurality of weak signal beacons, with a relatively weak intensity compared to the intensity of the first Bluetooth signal; and
a mobile device configured to store signal properties of the beacons including the strong signal beacon and the plurality of weak signal beacons corresponding to the identification numbers of the strong signal and the weak signal beacons and determine whether Bluetooth signal reception sensitivity of the mobile device is normal based on the identification numbers of the strong signal and the weak signal beacons included in the Bluetooth signal received by the mobile device and the signal properties corresponding to the identification numbers of the beacons and determine a location of the mobile device relative to the beacons based on a result of the determining whether the Bluetooth signal reception sensitivity of the mobile device is normal,wherein if only the first Bluetooth signal of the strong signal beacon is received, and the second Bluetooth signal of the plurality of weak signal beacons is not received, the mobile device determines the Bluetooth signal reception sensitivity as abnormal, and when the first Bluetooth signal of the strong signal beacon is continuously received for a predetermined period of time or longer, the mobile device determines its location to be within the Bluetooth signal range of the strong signal beacon.

Abstract
Provided are a system and method for positioning a mobile device by using a Bluetooth signal, and more particularly, to a system and method for positioning a mobile device by using a Bluetooth signal, in which a location of a user carrying a mobile device is effectively determined by using the mobile device receiving a Bluetooth signal, and a method of positioning the mobile device.
Provided are a system and method for positioning a mobile device by using a Bluetooth signal, in which a location of the mobile device may be more accurately determined by considering a Bluetooth signal receiving environment of the mobile device when providing a service and method of determining a location of the mobile device by using a Bluetooth signal.

9. A method of positioning a mobile device by using a Bluetooth signal, in which the mobile device receives the Bluetooth signal, which is periodically transmitted by a beacon, to determine a location of the mobile device, the method comprising:
-
(a) storing first identification number of a strong signal beacon that periodically transmits a first Bluetooth signal including the first identification number of the strong signal beacon with a relatively strong intensity and a second identification number representing each of a plurality of weak signal beacons arranged within a Bluetooth signal range of the strong signal beacon, wherein each of the plurality of weak signal beacons is configured to transmit a second Bluetooth signal having the second identification number of the corresponding weak signal beacon with a relatively weak intensity compared to the intensity of the first Bluetooth signal of the strong signal beacon, and signal properties of the beacons including the strong signal beacon and the plurality of weak signal beacons correspond to the identification numbers of the beacons in the mobile device; (b) receiving first and second Bluetooth signals transmitted by the beacons, determining the first and second identification numbers of the strong and weak signal beacons included in the first and second Bluetooth signals, and determining the signal properties of the strong and weak signal beacons that transmitted the Bluetooth signals, wherein the receiving is performed by the mobile device; (c) determining whether a Bluetooth signal reception sensitivity of the mobile device is normal based on the identification numbers and the signal properties of the beacons included in the received first and second Bluetooth signals, wherein the determining is performed by the mobile device; and (d) determining the location of the mobile device relative to the beacons based on a result of (c), wherein in (c), when the mobile device receives only the first Bluetooth signal of the strong signal beacon but not the second Bluetooth signal of the plurality of weak signal beacons, the mobile device determines its Bluetooth signal reception sensitivity as abnormal, and wherein in (d), if the first Bluetooth signal of the strong signal beacon is continuously received for a predetermined period of time or longer, the mobile device determines the location of mobile device to be within the Bluetooth signal range of the strong signal beacon. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
