Hereinafter, with reference to the accompanying drawings will be described the configuration of a customized content providing system using the location information when getting on and off the taxi according to the present invention.

1 is a reference diagram illustrating a state in which a reader is installed inside a taxi, and FIG. 2 is a customized content providing system using location information when getting on and off a taxi according to the present invention connected to a taxi, a credit card company, a notification server, and a smartphone. This is a network diagram explaining the relationship.

As shown in FIG. 2, the taxi 10 provides the passenger's credit card serial number and the merchant information of the reader 11 to the control server 12 or the customized content providing system 100 when the passenger gets on and off. .

To this end, the taxi 10 is provided with a reader 11, as shown in FIG. 1, and the passenger tags once on the reader 11 using a credit card at the time of getting on, and at the time of getting off to confirm the fare. The driver operates the reader 11.

In this case, when the credit card is tagged, the reader 11 recognizes the serial number of the credit card and transmits its merchant information to the credit card company server 13 through the mobile communication network. On the other hand, when there is a separate operation when the passengers get off, similarly transmits the serial number of the credit card and its own merchant information to the credit card company server 13 through the mobile communication network.

On the other hand, the information used by credit card merchants to identify themselves generally includes a business name, a telephone number, in the case of a taxi 10 includes a license plate number of the taxi.

The customized content providing system 100 obtains information about the credit card serial number, the coordinates of the reader 11, and the taxi 10 from the credit card company server 13 through the process described below.

Thereafter, the customized content providing system 100 selects predetermined contents to be provided to the smartphone 20 carried by the taxi passenger and transmits the predetermined contents to the notification server 14 in the form of a notification package, and the smartphone 20 periodically. By connecting to the notification server 14 and providing a device token, the notification package is received and displayed on the standby screen.

Hereinafter, a method of providing customized content using location information when getting on and off a taxi according to the present invention will be described in detail with reference to the flowcharts shown in FIGS. 5 and 6.

First, as shown in FIG. 5, when a passenger rides a taxi and tags his credit card to the reader 11 provided in the taxi 10, the reader 11 acquires the serial number of the credit card. At this time, since the contact type and the non-contact RF (Radio Frequency) reader are used interchangeably, the tagging does not necessarily mean that the card is brought into contact with the reader, but includes the act of bringing the reader 11 close enough to be read.

On the other hand, when the serial number of the credit card is obtained in this way, the reader 11 transmits it to the credit card company server 13 through the mobile communication network together with its affiliated store information (S101).

The received credit card company server 13 determines whether the received credit card serial number belongs to the service list (S102). The service list is a file listing credit card serial numbers, and the credit card company server 13 residing them in a memory and determining whether the same credit card serial number exists in the service list file when the credit card serial number is received.

The credit card company server 13, on the other hand, obtains the coordinate values of the reader 11 from the mobile communication company server 12 at the same time. Since the reader 11 transmits its merchant information and the like to the credit card company server 13 through the mobile communication network, the mobile communication company server 12 may not know the transmitted data, but the distance between the reader 11 and the base station By calculating the coordinate value of the reader 11 can be grasped.

When the coordinate value of the reader 11 is obtained as described above, the credit card company server 13 generates taxi information including the taxi number or the information of the taxi company corresponding to the merchant information of the reader. It encodes according to a predetermined data structure together with the coordinate values of the reader.

The data structure may be configured as shown in Table 1 below.

A B B B B B B B B B B B B B B B B C C C C C D D D D D D D D

(However, A: header, B: credit card serial number, C: taxi information, D: coordinate value)

The header can be expressed as 1 byte. The credit card serial number can be expressed as 16 bytes, and the coordinate value can be represented as 3 decimal places, and can be represented as 12 bytes for each of 6 bytes of latitude and longitude. Since it can be displayed, it can be determined variably according to its length.

Thereafter, the encoded data is transmitted to the customized content providing system 100. In this case, in order to secure the integrity of the security, it is preferably transmitted through a dedicated network (S103).

Upon receiving this, the customized content providing system 100 selects a value closest to the received coordinate value among names on the map (S104). For example, if the received coordinate value has a latitude of 37.31 and a longitude of 127.4, the name of the map data closest to the corresponding coordinate value is selected "cheongdam bridge south end".

Thereafter, the customized content providing system 100 dynamically generates a web page using the collected information. The included information includes time information at the time when the credit card serial number is received in step 103, and in step S103. The received taxi information, the name on the map selected in step S104 is included. Meanwhile, the map image of the location to which the coordinates received in step 103 belong may be included. In this case, the coordinates may be displayed on the map image.

Figure 4 (c) shows how to access the web page generated in this way using the smart phone 20, according to this "Ride time: 1 July 13:00," "Get off time : July 1, 13:30 pm "," Taxi number: Seoul Taxi Association No. 1234 "and information related to getting on and off the taxi is displayed, and the location and the getting off location is displayed on the map image at the bottom can confirm.

The dynamically generated web page is hosted for access through a browser (S105).

On the other hand, the customized content providing system 100 withdraws the device token of the passenger's smart phone 20 corresponding to the credit card serial number from the database (S106).

Subsequently, a character string including time information at the time when the credit card serial number is received in step 101, taxi information received in step S103, and a name on the map selected in step S104 is generated and used as a payload. By generating the notification package by combining the withdrawn device token (S107). In this case, the payload may include a link of the web page generated in step S106.

When the notification package is generated as described above, the customized content providing system 100 accesses the notification server 14 through a wired / wireless communication network, authenticates using a dedicated application identifier of the smart phone 20, and transmits the generated notification package (S108). ).

Authentication using a dedicated application identifier means a procedure for the notification server 14 to recognize that the notification package is for a corresponding application of the smartphone 20.

Meanwhile, when the notification server 14 receives the notification package, the notification server 14 stores the notification package. When the notification server 14 receives the device token from the smart phone 20 connected through the mobile communication network or the wired / wireless communication network, the notification package corresponding to the received device token is received. If there is a query to see if it exists, provides the smart phone 20 to download it.

As shown in (a) of FIG. 4, a popup displayed on the standby screen of the smart phone 20 displays the string "You have boarded a taxi 1234 near Yeoksam Station. Please run the APP for detailed information." In this way, the information on the taxi is provided to the passenger's smart phone 2 so that the passenger can use the taxi safely.

In addition, the passenger may execute a dedicated application to access the web page of the received link as shown in FIG. Such a web page can be accessed not only by the passenger but also by a third party related to the passenger using a personal computer, so that the passenger can move in real time through the taxi.

On the other hand, Figure 6 describes the process after providing the notification package according to the passenger's taxi ride in this way.

First, when the driver disembarks when the driver operates the reader 11 provided in the taxi 10, the reader 11 credits the serial number of the passenger's credit card and his / her affiliated store information obtained at the time of boarding through the mobile communication network. The card company server 13 transmits the data (S109).

The credit card company server 13 receiving the same checks whether the credit card serial number received in the step S101 and the credit card serial number received in the step S109 are matched. If it proceeds to the next step (S110).

If there is a match, the credit card company server 13 obtains the coordinate value of the reader 11 from the mobile communication company server 12 and transmits it through the private network to the customized content providing system together with an identifier for identifying the data transmitted in step S103. (S111).

The received customized content providing system 100 is updated by further displaying the coordinates of the taxi drop-off point received on the map image displayed on the web page dynamically generated in step S105 (S112).

In this case, as shown in (c) of FIG. 4, the coordinate values of the boarding point and the boarding point may be displayed at the same time. The customized content providing system 100 may further include a string indicating the boarding point or the getting off point, respectively. In addition, a straight line or a curve connecting the riding point and the discharging point may be displayed so that the movement route can be intuitively understood.

On the other hand, the customized content providing system 100 determines that the passengers safely get off the taxi, and withdraws the content related to the getting off location from the database (S113).

For example, as shown in (b) of FIG. 4, a string "Gangnam Station ABCD Bakery Sale is being displayed" is displayed on the pop-up displayed on the standby screen of the smart phone 20. Such content is located in the location "Gangnam Station". It can be seen that the

As such, when the content related to the location information is selected, the customized content providing system 100 generates a notification package by combining the selected content with the device token extracted in step S106 (S114).

Thereafter, the access server 14 is connected to the notification server 14 through a wired / wireless communication network and authenticates using a dedicated application identifier of the smart phone 20, and transmits the generated notification package (S115).
