Beacon is a short-distance communication technology that transmits information using Bluetooth communication and identifies the location of a communication terminal. A beacon is a device that uses a wireless communication technology based on the Bluetooth 4.0 (BLE) protocol, and can communicate with a terminal (smart devices including smartphones) up to a radius of up to 70 m. A guide service or a mobile coupon may be provided as soon as visitors enter the store. In addition, since a beacon terminal supporting low-power BLE (Bluetooth Low Energy) technology is used, battery consumption is small. In the case of GPS, there is an error of several tens of meters, whereas a beacon can measure a precise location of up to 5 cm, which can be advantageous, especially when controlling a terminal using a beacon indoors.

In the present invention, the first terminal 110 and the second terminal 120 are, for example, a computer, an Ultra Mobile PC (UMPC), a workstation, a net-book, a Personal Digital Assistants (PDA), and a portable (portable). ) As one of electronic devices such as a computer, a web tablet, a wireless phone, a mobile phone, a smart phone, and a portable multimedia player (PMP), an application related to an embodiment It may include any electronic device capable of being installed and executed.

In the present invention, the first terminal 110 may serve as a beacon terminal or may be an electronic device including a beacon terminal module. Also, when the second terminal 120 is located within the specific area 130 , the second terminal 120 may be an electronic device that receives the beacon data received from the first terminal 110 and determines whether to activate various functions. Furthermore, the second terminal 120 may include a beacon terminal module, like the first terminal 110, for encryption.

The first terminal 110 transmits beacon data to the second terminal 120 located within the specific area 130, and the second terminal 120 may control Internet and telephone functions based on the received beacon data. have.

In the present invention, the specific area 130 may be a range set so that the second terminal 120 can receive the signal of the first terminal 110 by adjusting the signal strength of the first terminal 110 in advance. Accordingly, the specific area 130 is an area in which the second terminal 120 can be controlled by the first terminal 110 transmitting beacon data, and the specific area 130 is the signal strength of the first terminal 110 . It can be enlarged or reduced by adjusting the

The second terminal 120 may control the Internet and telephone functions based on the received beacon data using an application program or an application installed in the second terminal 120 . Therefore, when the first terminal 110 transmits beacon data, the second terminal 120 compares the received beacon data with the encrypted data generated by the second terminal 120 to control the function of the second terminal 120 . (or control) At this time, the application program (application program or application) may be downloaded through an external server through wireless communication.

Also, the first terminal 110 may include the same application program or application as the second terminal 120 .

2 is a block diagram illustrating a first terminal and a second terminal of a terminal control system according to an embodiment of the present invention.

The first terminal 210 and the second terminal 250 of FIG. 2 may correspond to the first terminal 110 and the second terminal 120 of FIG. 1 , respectively.

According to an embodiment of the present invention, the first terminal 210 may include a real time clock (RTC) 220 , an encryption module 230 , and a communication module 240 .

The RTC 220 may be a computer clock that keeps the current time. In the present invention, the RTC 220 is produced by manufacturers such as Epson, Intersil, IDT, Maxim, NXP Semiconductors, Texas Instruments, or ST Microelectronics. it could be

The RTC 220 may calculate (or calculate) the current time by increasing the counter value in real time. Accordingly, the RTC 220 calculates the current time whenever new beacon data is generated and provides it to the encryption module 230 , and the encryption module 230 provides beacon data that is encrypted data based on the current time provided from the RTC 220 . can create

According to an embodiment of the present invention, the encryption module 230 may obtain the current time from the RTC 220 and generate beacon data that is encrypted data through an encryption process. Specifically, the encryption module 230 may generate beacon data using the current time and specific data for encryption. In this case, the specific data may be a combination of numbers and/or letters preset for encryption and stored in the first terminal 210 . In other words, the specific data may be a key set in advance to prevent another external encryption or decryption device from generating or decrypting the same beacon data as the encryption module 230 .

In the present invention, the specific data may be shared through applications installed in the first terminal 210 and the second terminal 250 . Therefore, if the first terminal 210 and the second terminal 250 generate encrypted data based on the same time, the first terminal 210 and the second terminal 250 always store the same specific data, The same encrypted data may be generated.

Also, the specific data may be changed by an administrator or a user of the first terminal 210 , and the changed specific data may be shared to the second terminal 250 through an application.

In the present invention, the encryption module 230 may generate beacon data using an encryption algorithm such as DES, TDES, AES, SEED, RSA, ARIA, SEED, ARIA, or 3DES. Here, the ARIA encryption algorithm is a public-private block symmetric key encryption algorithm developed by the National Security Research Institute.

The first terminal 210 that has completed generating the beacon data may transmit the beacon data to the second terminal 270 through the communication module 240 .

According to an embodiment of the present invention, the communication module 240 may transmit information about the current operation mode of the first terminal 210 together with beacon data. The operation mode may include a blocking mode and a release mode.

The blocking mode may be a mode for inactivating the Internet and telephone functions of the second terminal 250 , and the canceling mode may be a mode for activating the Internet and telephone functions again. In an embodiment, the operation mode may be selected by the user of the first terminal 210 . For example, the user may select an operation mode as a blocking mode when starting a class, and may select the operation mode as a cancellation mode after the class ends.

Alternatively, the first terminal 210 may normally operate in the cancellation mode, and may operate in the blocking mode if necessary. Conversely, the first terminal 210 may normally operate in the blocking mode, and may operate in the cancel mode if necessary. For example, when the first terminal 210 is installed in a university lecture room, it may operate in the cancel mode during non-class or test time, and may operate in the cut-off mode during class or test time. Conversely, when the first terminal 210 is installed in a place where a mobile phone cannot be used, such as a high school, it may operate in the blocking mode from the start time to the dismissal time, and then operate in the cancel mode after the school time.

According to an embodiment of the present invention, the first terminal 210 may generate new beacon data in a preset time unit. For example, the first terminal 210 may generate new beacon data every 10 minutes. Also, within the preset time unit, the first terminal 210 may transmit the same beacon data to the second terminal 250 in real time until the next new beacon data is generated. For example, if the RTC 220 calculates the time at 10:00 and the encryption module 230 generates beacon data based on 10:00, the first terminal 210 performs the Beacon data generated based on 10:00 can be transmitted. In this case, the preset time unit may include seconds, minutes, hours, days, weeks, and months. Also, the preset time unit may be shared by the first terminal 210 and the second terminal 250 through an application.

Also, the first terminal 210 may periodically transmit the same beacon data within a preset time unit. In this case, the period may include seconds, minutes, hours, and the like. Accordingly, all of the second terminals 120 entering the specific area 130 within a predetermined time unit before generating new beacon data may receive the same beacon data. For example, if the predetermined time unit is 10 minutes and new beacon data is generated at 10:00, the second terminal enters the specific area 130 at 10:05 and the specific area 130 at 10:07. ) entering the second terminal may receive the same beacon data. Also, the first terminal 210 may periodically generate the same beacon data within a preset time unit and then transmit it to the second terminal 250 .

According to an embodiment of the present invention, in addition to generating or transmitting the same beacon data in a preset time unit, the first terminal 210 starts or ends beacon data generation according to a preset data generation start time and end time. can do. Specifically, the user of the first terminal 210 sets the first terminal 210 by setting the data generation start time and end time, and the first terminal 210 sets the data generation start time and end time according to the preset data generation start time and end time. Beacon data generation can be started or stopped. Also, the first terminal 210 may generate beacon data for a specific time. For example, when the first terminal 210 is installed in a lecture room, the first terminal 210 generates beacon data in the blocking mode according to the start time of a class (or exam), etc., and enters the cancel mode according to the end time of the class. Beacon data can be generated for a certain period of time and the beacon data generation can be terminated. The data generation start time and end time can be newly set whenever the user of the first terminal 210 desires.

According to an embodiment of the present invention, the first terminal 210 may generate beacon data according to a user's request of the first terminal 210 . For example, when the user of the first terminal 210 possesses the first terminal 210 , the user selects an operation mode and inputs a beacon data generation request to the first terminal 210 to the first terminal ( 210 ). 210) to generate beacon data.

When the beacon data generation is completed, the encryption module 230 may provide the generated encrypted data to the communication module 240 . Also, the RTC 220 may provide the current time provided to the encryption module 230 to the communication module 240 to generate beacon data. Accordingly, the communication module 240 may transmit beacon data or beacon data and the current time to the second terminal 250 through a network (based on Bluetooth 4.0 (BLE) protocol). In one embodiment, if the preset time unit is not shared with the second terminal 250 , the second terminal 250 may generate encrypted data based on the current time calculated by the RTC 220 . have.

According to an embodiment of the present invention, since the first terminal 210 is provided with a separate power supply (not shown), when there is no need to generate the beacon data, the beacon data is not generated in a state in which the power is cut off. It may not be.

As shown in FIG. 2 , the second terminal 250 may include a communication module 260 , an RTC 270 , an encryption module 280 , and a control unit 290 .

According to an embodiment of the present invention, the communication modules 240 and 260 may communicate with various types of external devices according to various types of communication methods. The communication unit 210 may include at least one of a Wi-Fi chip, a Bluetooth chip, a wireless communication chip, and an NFC chip.

The Wi-Fi chip and the Bluetooth chip may perform communication using a WiFi method and a Bluetooth method, respectively. In the case of using a Wi-Fi chip or a Bluetooth chip, various types of connection information such as an SSID and a session key are first transmitted and received, and then various types of information can be transmitted and received after communication connection using the same. The wireless communication chip refers to a chip that performs communication according to various communication standards such as IEEE, ZigBee, 3rd Generation (3G), 3rd Generation PartnershIP Project (3GPP), and Long Term Evolution (LTE). The NFC chip refers to a chip operating in an NFC (Near Field Communication) method using a 13.56 MHz band among various RF-ID frequency bands such as 135 kHz, 13.56 MHz, 433 MHz, 860 to 960 MHz, 2.45 GHz, and the like.

According to an embodiment of the present invention, the communication module 260 of the second terminal 250 may receive at least one of beacon data, an operation mode signal, and a current time transmitted by the first terminal 210 .

The RTC 270 of the second terminal 250 may be a computer clock that maintains the current time in the same way as the RTC 220 of the first terminal 210 . Accordingly, the RTC 270 may calculate (or calculate) the current time by increasing the counter value in real time.

Therefore, the RTC 270 calculates the current time each time the second terminal 270 generates new encrypted data and provides it to the encryption module 280, and the encryption module 280 at the current time provided from the RTC 270. Based on the encryption data can be generated.

According to an embodiment of the present invention, the encryption module 280 may obtain the current time from the RTC 270 and generate encrypted data through an encryption process. Specifically, the encryption module 280 may generate encrypted data using the current time and specific data for encryption. In this case, the specific data may be data shared with the first terminal 210 that is preset for encryption.

In this case, since there is inevitably a difference between the time when the first terminal 210 generates the beacon data and the time when the second terminal 250 generates the encrypted data, the beacon data and the encrypted data are always different. Accordingly, in order to correct this, the first terminal 210 and the second terminal 250 need to share a preset time unit. If the second terminal 250 generates encrypted data within the preset time unit, the encryption module 280 compares the current time calculated by the RTC 270 with the current time calculated by the RTC 220 of the beacon. Encrypted data can be generated by considering the same time. For example, when the preset time unit is 10 minutes and the first terminal 210 generates beacon data based on the 10:00 minute time, the encryption module 280 receives the encrypted data from the RTC 270 to generate the encrypted data. Even if the acquired time is 10:06:10, since the current time has not elapsed from 10 to 10 minutes, the encryption module 280 may generate the encrypted data by considering the current time as 10:00.

According to an embodiment of the present invention, if the time calculated by the RTC 220 is also received through the network, the encryption module 280 does not need to check a preset time unit, and the received current time and specific data Encrypted data may be generated based on the In this case, if the same specific data as the first terminal 210 is stored in the second terminal 250 , the beacon data and the encrypted data generated in the second terminal 250 are inevitably the same.

According to an embodiment of the present invention, when the encryption module 280 generates encrypted data, the controller 290 may compare the encrypted data with the received beacon data. Based on the comparison, the controller 290 may control the second terminal 250 by determining whether to activate the Internet and telephone functions. Specifically, the control unit 290 receives the operation mode signal indicating that the blocking mode or the cancellation mode is in the blocking mode or the cancellation mode from the first terminal 210 through the communication module 260, and according to the comparison result of the beacon data and the encrypted data, Internet and telephone functions You can decide whether to activate or not.

According to an embodiment of the present invention, when the first terminal 210 transmits that the current operation mode is the blocking mode, the control unit 290 compares the beacon data and the encrypted data, and when both are the same, the Internet and telephone functions are provided. can be deactivated. Conversely, when the first terminal 210 transmits that the current operation mode is the cancellation mode, the controller 290 compares the beacon data and the encrypted data, and when both are the same, the Internet and telephone functions can be activated. However, the second terminal 250 does not necessarily need to receive information on the current operation mode from the first terminal 210 . For example, the second terminal 250 may receive information on the current operation mode from an external server (not shown) through an application installed in the second terminal 250 . In addition, as in the case described later, if the second terminal 250 determines activation of the Internet and telephone functions based on location, the first terminal 210 and the second terminal 250 may not need a separate operation mode. have.

According to an embodiment of the present invention, when the second terminal 250 leaves the place where the beacon is installed, the controller 290 may activate the Internet and telephone functions. Specifically, the second terminal 250 uses the location tracking technology to determine the current location of the second terminal 250 , and the controller 290 controls the second terminal 250 when the second terminal 250 deviates from the specific area 130 , the Internet and re-enable the phone function. In this case, the location tracking technology is a base station geofencing technology, Bluetooth communication (Bluetooth Low-Energy, BLE), a Wi-Fi positioning system (WiFi Positioning System, WPS), a sound QR (Sound QR, SQ) using an inaudible frequency band ), a global positioning system (GPS), and an infrared-based positioning technology (IR, infrared), but is not limited thereto.
