Description

Mobile commerce service device, mobile commerce service method based on ultrasonic wave transmitter/receiver and computer readable medium having computer program recorded thereon}

The present invention relates to a mobile commerce service device, a mobile commerce service method using an ultrasonic transceiver, and a recording medium on which a computer program is recorded, and in particular, a plurality of location analysis procedures for determining the location of a user located within a certain area around a specific point in a store. It relates to a mobile commerce service device for providing mobile commerce service by analyzing based on, a mobile commerce service method using an ultrasonic transceiver, and a recording medium on which a computer program is recorded.

As ICT (Information and Communication Technology) technology is rapidly developed and utilized, convergence of various services and systems is rapidly progressing. ICT technology through GPS (Global Positioning System) and Wi-Fi (Wireless Fidelity) has been applied to real life through the combination of performance improvement of devices owned by individuals and development of location analysis technology. In particular, domestic and foreign companies provided location services for indoor spaces through IT technology.

These technologies include GPS, Wireless Local Area Network (WLAN), Ultra WideBand (UWB), and Bluetooth technology. GPS provides wide-area global coordinate system-based location information in an outdoor environment, but it is impossible to provide location information indoors and in dense urban areas, so research on wide-area indoor location recognition technology to supplement this is being actively conducted.

WPS (Wi-Fi Positioning System) is a WLAN-based positioning technology that uses Wi-Fi routers installed in various places to estimate the position of a terminal. It is known that the error range is about 5m. Because UWB uses impulses, the bandwidth is spread and occupies a lot of bandwidth, which can cause failure in other wireless communication systems that are already used. However, the distance measurement at a location where there is no obstacle interference between APs calculates a relatively accurate distance, but the error range increases as the number of obstacles increases and the distance increases.

As a recently used technology, there is a beacon based on Bluetooth Low Energy (BLE). Compared to the existing Bluetooth protocol, the biggest feature of BLE beacon is that it consumes less battery of smart mobile devices. Although such a BLE beacon is the most noteworthy technology for positioning of IPS in the future, it may be difficult to provide accurate location service as a single technology with current technology.

8 is a conceptual diagram illustrating a method for generating an ultrasonic signal according to an embodiment of the present invention.

8 discloses a method of identifying a user device by dividing a band of an ultrasonic signal when an ultrasonic transmitter/ultrasonic receiver communicates with a user device based on an ultrasonic signal.

Referring to FIG. 8 , an ultrasound signal band 800 may be divided into a plurality of bands, and each divided ultrasound signal band may be allocated as a radio resource for one user device 140 . For example, when identification information of the user device 140 is obtained through a secondary location determination procedure, through an ultrasonic signal band uniquely allocated to the user device 140 based on the identification information of the user device 140. Ultrasound can be transmitted.

After receiving identification information from the user device 140, the ultrasound transmitter may allocate an ultrasound division signal band to the user device 140. The ultrasound transmitter may determine an ultrasound signal band to be allocated to the user device 140 in consideration of the number of user devices 140 to be communicated with and current ultrasound signal band allocation.

After receiving the identification information of the user device 140, the ultrasonic transmitter performs communication with the user device 140 based on the ultrasonic division signal band assigned to the user device 140 to the user device 140. ) can be measured. The user device 140 may receive information about the allocated ultrasound segmentation signal band and transmit the duplicate ultrasound signal and user device identification information through the allocated ultrasound segmentation signal band.

The ultrasound transmitter/ultrasound receiver 100 may continuously track the location of the user device 140 based on an ultrasound signal transmitted through an allocated ultrasound division signal band.

The ultrasonic transmitter/ultrasound receiver 100 may determine the number of user devices 140 located within the mobile commerce service area through a primary location determination procedure. The ultrasound transmitter/ultrasound receiver 100 may change the allocated ultrasound split signal band based on the number of user devices 140 .

For example, if the number of user devices 140 within the mobile commerce service area is x or less, communication with the user device 140 may be performed using the entire ultrasonic signal band 800 without separate division. That is, in the case of x or less, when the transmission period is set differently from each other, collisions do not occur much in performing communication between the x number of user devices 140 and the ultrasonic transmitter/ultrasound receiver 100, so that a separate ultrasonic wave is generated. Division of the signal band 800 may not be performed.

Conversely, when the number of user devices 140 in the mobile commerce service area exceeds x, the ultrasonic signal band 800 may be divided. For example, when the number of user devices 140 in the mobile commerce service area is x to y (where y>x), the ultrasonic signal band 800 is divided into two to obtain a first ultrasonic divided signal band and a second ultrasonic signal band 800. It can be divided into 2 ultrasonic division signal bands. In this case, 1/2 of the user devices 140 communicate with the ultrasonic transmitter/ultrasound receiver 100 through the first ultrasonic splitting signal band, and the other 1/2 of the user devices 140 use the second ultrasonic splitting signal band. It is possible to communicate with the ultrasonic transmitter/ultrasonic receiver 100 through the

Similarly, when the number of user devices 140 is y to z (in this case, z>y) in the mobile commerce service area, the ultrasonic signal band is divided into three, resulting in a first ultrasonic division signal band and a second ultrasonic division signal band and a third ultrasonic split signal band. In this case, one-third of the user devices 140 communicate with the ultrasonic transmitter/ultrasonic receiver 100 through the first ultrasonic division signal band, and the other one-third of the user devices 140 communicate with the second ultrasonic division signal band. The remaining 1/3 of the user devices 140 may communicate with the ultrasonic transmitter/ultrasonic receiver 100 through the third ultrasonic split signal band.

In this way, the possibility of collision that may occur during ultrasonic signal-based communication can be reduced through the division of the ultrasonic signal band.

In the above case, the ultrasonic transmitter/ultrasound receiver 100 and the mobile commerce service providing device 120 allocate a virtual identifier of the user device 140 to the identification information of the actual user device 140 for each band. you can manage it. In addition, the ultrasound transmitter/ultrasound receiver 100 may determine an ultrasound signal band allocated for each virtual ID in which the user device 140 operates.

For example, if 10 user devices (user device 1 to user device 10) 140 exist in the mobile commerce service area, the ultrasonic transmitter/ultrasound receiver 100 is provided to each of the user devices 1 to 5. Virtual ID1 to virtual ID5 may be assigned to each of the virtual IDs, and a first ultrasound division signal band may be assigned. In addition, the ultrasound transmitter/ultrasound receiver 100 may allocate virtual ID6 to virtual ID10 to each of the user devices 6 to 10 and allocate a second ultrasound division signal band.

9 is a conceptual diagram illustrating the operation of the mobile commerce service providing device 120 according to an embodiment of the present invention.

In FIG. 9 , a mobile commerce service operation considering user identification information of the mobile commerce service providing device 120 is disclosed.

Referring to FIG. 9 , the mobile commerce service providing device 120 may provide a mobile commerce service for the user device 140 based on a virtual ID mapped to identification information of the user device 140 . The mobile commerce service providing device 120 may provide a mobile commerce service by grouping user devices according to membership levels.

The mobile commerce service providing device 120 provides, for example, mobile commerce service 1 (915) to members of level 1 (910) and mobile commerce service 2 (925) to members of level 2 (920), , Mobile commerce service 3 (935) can be provided to members of level 3 (930). As a specific example, mobile commerce service 1 915 may provide a coupon with a discount rate of 10%, mobile commerce service 2 925 may provide a coupon with a discount rate of 20%, and mobile commerce service 3 935 may provide a coupon with a discount rate of 30%.

The mobile commerce service providing device 120 classifies at least one user device 140 corresponding to a first-class member into group 1 based on the user's identification information, and classifies at least one user device 140 corresponding to a second-class member. ) may be classified as group 2, and at least one user device 140 corresponding to a level 3 member may be classified as group 3.

After classification, the mobile commerce service providing device 120 provides mobile commerce service 1 915 to the user device 140 included in group 1, and provides mobile commerce service 2 (915) to the user device 140 included in group 2 ( 925), and mobile commerce service 3 935 may be provided to the user device 140 included in group 3.

For the mobile commerce service by level as described above, data for the mobile commerce service may be masked by an identifier according to a member level. For example, data for mobile covers service 1 915 may be masked by identifier 1 that only the user device 140 included in group 1 can decode. Accordingly, data for mobile covers service 1 915 can be decoded only by the user device 140 included in group 1. In the same way, data for mobile cover service 2 925 may be masked by identifier 2 that only the user device 140 included in group 2 can decode.

In addition, when the mobile commerce service providing device 120 detects the identification information of the new user device 140 in the signal transmitted by the ultrasonic transmitter/ultrasonic wave receiver 100, the user device 140 is considered to be identified. The user device 140 may be included in a specific group.

In addition, the mobile commerce service providing apparatus 120 may provide a mobile covers service by classifying services according to levels and services not considering the level. The graded service is a service provided considering the grade of the user device 140, and the grade-non-considered service is a service provided without considering the grade of the user device 140. In the case of a service by level, the mobile commerce service providing device 120 may transmit data for the mobile commerce service by considering the level of the user device 140 as described above and masking it with an identifier for each level. In the case of a service not considering a level, the mobile commerce service providing device 120 may not consider the level of the user device as described above and may transmit data for the mobile commerce service without masking based on an identifier for each level.

According to an embodiment of the present invention, the mobile commerce service providing device 120 may manage information on the mobile commerce service so that it is not transmitted to the same user device 140 unnecessarily and repeatedly.

The mobile commerce service providing device 120 may periodically transmit information for the mobile commerce service. In this case, if the line where the user is located in front of the POS or the sales counter is long, the user may continuously receive overlapping information for the mobile commerce service, and the user's fatigue due to the continuous transmission of the same information may increase. . Therefore, according to an embodiment of the present invention, the mobile commerce service providing device 120 predicts the number of times the information is received by the user and when it is predicted that the information for the same mobile commerce service is transmitted more than the set number of times, the corresponding user device 140 ) may stop transmitting information for a mobile commerce service.

The mobile commerce service providing device 120 may calculate the time the user device 140 stayed within a certain area. The location of the user device 140 may be tracked based on the ultrasonic transmitter/ultrasound receiver 100, and the mobile commerce service providing device 120 may calculate the time the user device stays within a certain area. The mobile commerce service providing device 120 determines the number of times the mobile commerce service information is transmitted to the user device in consideration of the time the user device stays within a certain area and the transmission cycle of information for the mobile commerce service (hereinafter referred to as mobile commerce service information). Predictable. The predicted value of the number of transmissions of the mobile commerce service information to the user device may be expressed as a term of an estimated number of transmissions of the mobile commerce service information.

If the estimated number of transmissions of mobile commerce service information exceeds a preset maximum number of transmissions (eg, 1 to 2 times), the mobile commerce service information may not be transmitted to the user device 140 . The mobile commerce service providing device 120 may set the maximum number of information transmissions, and limit transmission of information for the mobile commerce service to the user device 140 according to the set maximum number of information transmissions.

As a specific example, the mobile commerce service providing device 120 may manage information about the time each of the user devices 1 to 5 stayed within a certain area (hereinafter referred to as a mobile commerce service area) where each of the user devices 1 to 5 can receive the mobile commerce service. It may be assumed that user device 1 stays within the mobile commerce service area for 5 minutes, user device 2 for 4 minutes, user device 3 for 3 minutes, user device 4 for 2 minutes, and user device 5 for 1 minute. If the transmission period of the mobile commerce service information is 2 minutes, the mobile commerce service providing device 120 calculates that the number of transmissions of the mobile commerce service information of user device 1 is predicted to be 2 times, and the number of times of transmission of mobile commerce service information of user device 2 is predicted to be 2 minutes. 2 times, the predicted number of mobile commerce service information transmission of user device 3 is 1 time, the predicted number of mobile commerce service information transmission of user device 4 is 1 time, and the predicted number of mobile commerce service information transmission of user device 5 is 0 times. .

If the set maximum number of transmissions of information is two times, the mobile commerce service providing device 120 may transmit mobile commerce service information only to user devices 3, 4, and 5 excluding user devices 1 and 2. .

Instead of predicting the number of transmissions of information for the mobile commerce service, the number of transmissions of information for the mobile commerce service may actually be stored in a database and managed. That is, the database may store the number of transmissions of information for mobile commerce service for each user device, and the mobile commerce service providing device 120 considers the number of transmissions of information for mobile commerce service for each user device stored in the database. It is possible to determine whether or not to transmit information for a mobile commerce service to the device.

As a specific example, the database of the mobile commerce service providing device 120 stores the actual number of transmissions, so that the number of transmissions of mobile commerce service information of user device 1 is 2 times, the number of transmissions of mobile commerce service information of user device 2 is 2 times, and the number of transmissions of mobile commerce service information of user device 3 is 2 times. The number of transmissions of mobile commerce service information of user device 4 may be stored as 1 time, the number of transmissions of mobile commerce service information of user device 4 as 1 time, and the number of transmissions of mobile commerce service information of user device 5 may be stored as 0 times. If the set maximum number of transmissions of information is two times, the mobile commerce service providing device 120 may transmit mobile commerce service information only to user devices 3, 4, and 5 excluding user devices 1 and 2. .

According to another embodiment of the present invention, information on the number of times mobile commerce service information has been received by the user device 140 may be transmitted to the mobile commerce service providing device 120 . For example, when receiving mobile commerce service information from the mobile commerce service providing device 120, the user device 140 may transmit an acknowledgment (ACK) signal in response to the mobile commerce service information. The ACK signal transmitted by the user device 140 may include information about the number of times the corresponding mobile commerce service information has been received. For example, when the maximum number of information transmission is set to 3, the ACK signal may include a 2-bit mobile commerce service information reception count field. If the value of the service information reception count field is '00', the service information reception count field means one reception of mobile commerce service information, and if the service information reception count field is '01', the service information reception count field means reception of mobile commerce service information twice, and when the value of the service information reception count field is '10', it means reception of mobile commerce service information three times, and the value of service information reception count field is '11'. ', this may mean reception of mobile commerce service information 4 times. The mobile commerce service providing device 120 may determine whether to additionally provide mobile commerce service information based on the ACK signal.

Alternatively, the user device 140 may directly set the maximum number of receptions of the mobile commerce service information, and the corresponding mobile commerce service information is not additionally transmitted through an ACK signal transmitted by the user device 140 according to the set maximum number of receptions. You can transmit information requesting silence. When receiving mobile commerce service information from the mobile commerce service providing device 120, the user device 140 may transmit an ACK signal in response to the mobile commerce service information. The ACK signal transmitted by the user device 140 may additionally include bit information indicating not to transmit mobile commerce service information. For example, when the value of the bit indicating not to transmit the mobile commerce service information is 1, the mobile commerce service providing apparatus 120 may not additionally transmit the mobile commerce service information. Conversely, when the value of the bit indicating not to transmit the mobile commerce service information is 0, the mobile commerce service providing device 120 may additionally transmit the mobile commerce service information.

Also, according to an embodiment of the present invention, the mobile commerce service providing device 120 may determine a transmission period of mobile commerce service information based on the number of user devices 140 located within the mobile commerce service area. That is, when the number of user devices 140 located within the mobile commerce service area is relatively large, the time to provide the mobile commerce service is relatively long because the waiting time within the mobile commerce service area is long. Accordingly, the mobile commerce service providing device 120 may provide the mobile commerce service to the user device 140 even if the transmission period of the mobile commerce service information is set to be relatively long. On the other hand, when the number of user devices located in the mobile commerce service area is relatively small, the time to provide the mobile commerce service is relatively short because the waiting time within the mobile commerce service area is short. Accordingly, the mobile commerce service providing device 120 may provide the mobile commerce service to the user device 140 by setting a relatively short transmission period of the mobile commerce service information.

The mobile commerce service providing device 120 obtains information about the number of user devices 140 located within the mobile commerce service area based on the location information of the user devices 140 received from the ultrasonic transmitter/ultrasound receiver 100. can The mobile commerce service providing device 120 may classify the number of user devices 140 into predetermined intervals and determine a transmission period of mobile commerce service information according to the classified interval. A transmission period of mobile commerce service information according to the number of user devices is predefined in a table or may be set according to settings of a mobile commerce service provider. For example, when the number of user devices 140 located within the mobile commerce service area is less than 10, the transmission period of mobile commerce service information is set to 1 minute, and the number of user devices 140 located within the mobile commerce service area is 10. If the number is less than 20, the transmission period of the mobile commerce service information is set to 2 minutes, and if the number of user devices 140 located in the mobile commerce service area is 20 or more and less than 30, the transmission period of the mobile commerce service information is It can be set to 3 minutes. Repeated transmission of unnecessary mobile commerce service information may be restricted based on the setting of the transmission period of the adaptive mobile commerce service information.

10 is a conceptual diagram illustrating a method of determining a target user device to which mobile commerce service information will be transmitted according to an embodiment of the present invention.

10 discloses a method of determining a target user device 1000 to receive mobile commerce service information among user devices located within a mobile commerce service area.

Referring to FIG. 10 , all user devices located within a mobile commerce service area may not be devices to receive mobile commerce service information because shopping malls and stores have a large floating population. Mobile commerce service information may be transmitted as the target user device 1000 by selecting only a user device waiting for payment in front of a sales counter from among all user devices located within the mobile commerce service area.

Various methods may be performed to determine the target user device 1000 among all user devices located within the mobile commerce service area. For example, it may be determined whether a user device located within the mobile commerce service area is the target user device 1000 based on a location change of the user device. In general, users wait in line in front of a sales counter or POS, and after the line decreases in a certain direction, the user and the clerk meet to perform a checkout procedure for products.

Accordingly, the mobile commerce service providing apparatus 120 may track the movement direction of the user device and determine only the user device moving in the direction in which the line decreases as the target user device 1000 . The mobile commerce service providing device 120 may have information about directions and areas where users generally cross lines. For example, the mobile commerce service providing device 120 may continuously receive images received from an imaging device in a store, and analyze the received images to determine directions and areas where users line up in the store. information can be obtained. The mobile commerce service providing device 120 selects a user device that lines up in a line and moves in a direction in which the line is reduced among all user devices located within the mobile commerce service area based on information on the direction and area where users generally line up, as the target user. It can be determined by the device 1000.

Also, according to an embodiment of the present invention, the mobile commerce service providing device 120 may determine, as the target user device 1000, a user device whose movement is equal to or less than a certain distance for a certain time within the mobile commerce service area of the user device. The mobile commerce service providing device 120 may perform the above determination on the assumption that a user device moving at a certain speed or less among user devices located within the mobile commerce service area is a user device that moves to a POS or a sales table for payment. . For example, the mobile commerce service providing apparatus 120 may calculate a moving speed for each user device within the mobile commerce service area and determine a user device having a moving speed equal to or less than a threshold speed as the target user device 1000 .

In addition, according to an embodiment of the present invention, the mobile commerce service providing device 120 determines whether the user device has received the mobile commerce service information, and if there is a user device that has not received the mobile commerce service information among the user devices, The clerk may be notified so that the user may be provided with the mobile commerce service.

If there are not many people in the store, the user device is not provided with the mobile commerce service and the user can directly perform a checkout procedure for the product with the clerk. In order to prevent such a case, the mobile commerce service providing device 120 may select a user device not provided with the mobile commerce service among user devices and notify the user of information about the mobile commerce service through a clerk.

For example, a separate signal may be transmitted to a user device of a user who performs a checkout procedure with a clerk within a mobile commerce service area to check whether mobile commerce service information is received. For example, the mobile commerce service server may transmit a mobile commerce service information acknowledgment request message to a user device performing a checkout procedure with a clerk. The mobile commerce service information reception confirmation request message may include information for confirming whether the mobile commerce service information has been received. The user device may receive the mobile commerce service information acknowledgment request message and transmit a response message to the mobile commerce service information acknowledgment request message. The response message may include information on whether mobile commerce service information has been received. When the response message indicates reception of mobile commerce service information, delivery of mobile commerce service information by a separate additional clerk is not required. However, when the response message indicates non-receipt of mobile commerce service information, delivery of information on mobile commerce service by a separate and additional clerk is required. In this case, the mobile commerce service providing device may notify the clerk's sales device of non-receipt of information on the user's mobile commerce service. The clerk may receive a message indicating non-receipt of information on the mobile commerce service of the user through the sales device, and directly orally convey the information on the mobile commerce service to the user.

Also, according to an embodiment of the present invention, information on different mobile commerce services may be provided for each area within the store. For example, a plurality of the above-described ultrasonic transmitter/ultrasound receiver 100 may be implemented in a store. Each of the plurality of ultrasound transmitters/ultrasound receivers 100 may be individually installed in a plurality of locations within a store to identify a user device located in a specific area within a store.

For example, ultrasonic transmitter 1/ultrasonic receiver 1, ultrasonic transmitter 2/ultrasonic receiver 2, ultrasonic transmitter 3/ultrasonic receiver 3, and ultrasonic transmitter 4/ultrasonic receiver 4 may be respectively installed in four places in the store.

Ultrasonic transmitter 1/ultrasonic receiver 1 is installed to provide mobile commerce service information related to a first product in a first zone in the store, and ultrasonic transmitter 2 / ultrasonic receiver 2 is installed to provide mobile commerce service information related to a second product in a second zone in the store. Installed to provide commerce service information, ultrasonic transmitter 3/ultrasound receiver 3 is installed to provide mobile commerce service information on a third product in a third zone in the store, and ultrasonic transmitter 4/ultrasonic receiver 4 is installed in the store It may be installed to provide mobile commerce service information related to a fourth product in a fourth zone. In this case, a user device located in the first area receives mobile commerce service information related to a first product, a user device located in a second area receives mobile commerce service information related to a second product, and a user device located in a third area receives mobile commerce service information related to a second product. The user device may receive mobile commerce service information related to the third product, and a user device located in the fourth area may receive mobile commerce service information related to the fourth product.
