The contents described in this section merely provide background information on the present embodiment and do not constitute the prior art.

Recently, near-field service solutions using Bluetooth based beacon, which is a near-field wireless communication technology (PAN), are being launched one after another. Near field communication (NFC) or Quick Response (QR), which is similar to Bluetooth beacons, requires a user to take action such as touching or manipulating the device to recognize a tag or code because the communication distance is short. It is possible to automatically recognize the user and obtain the location, and to provide various location-based services to the user.

In addition, the Bluetooth beacon can be used indoors and more sophisticated than GPS (Global Positioning System) based positioning, and can be used as a base technology to provide various services in buildings such as stadiums, exhibitions, art galleries, shops .

However, according to the conventional technology, when the user tag transmits a Bluetooth signal at a certain time, the AP device sequentially scans three control channels. This method has a problem in that a signal transmitted by the user tag may be missing if the user tag overlaps with the time of transmitting the Bluetooth signal and the channel change period or the idle period of the AP apparatus.

In addition, a signal transmitted by the user tag may be missing or the same tag information may be duplicated depending on the scanning time period of the AP device. If the distance between the AP device and the user tag is long, the signal strength is weak, There is a problem that the reliability of the Bluetooth signal processing is lowered.
