As shown in the drawing, the mobile coupon providing system according to the present invention includes a central server 10 managed and operated by a communication service provider.

The central server 10 is a part for connecting the portable terminal 20 subscribed to the communication service provider with the other portable terminal 20 'desired through the base station 30, and additional functions such as additional services and text message delivery. In charge of.

Looking at the configuration of the central server 10 in more detail, the central server 10 includes a controller 11 for managing the base station 30, and interworking with the exchange 13 to be described later.

The controller 11 is connected to a switch 13 that controls voice calls and various additional services, sets up a call path, and provides a connection function with other equipment and an external network.

The switch 13 is connected with a location registration register 15 in which the location and subscriber information of the subscriber's portable terminal 20 are stored. The location registration register 15 is a location of a home location register (HLR) in which subscriber information, service type, home exchanger (13) ID information, and the like are stored outside the home exchanger (13). It includes a Visitor Location Register (VLR) that registers the.

That is, when the portable terminal leaves the position registered as the home position, the position moved by the portable terminal is recorded in the visitor location register, so that the central server 10 searches for the home location register and the visitor location register. The location of the portable terminal can be determined.

Meanwhile, the exchange 13 is connected to a short message controller 17 for processing a short message and an additional service processing controller (not shown) for processing an additional service.

The short message controller 17 is a part for receiving and transmitting a short message received by the exchange 13, and the transmission number of the text message is a specific number preset by a communication provider (hereinafter, for convenience of description, a specific number is used). In the case of '8598', it is recognized as a coupon request message according to the present invention.

That is, when the transmission number of the transmitted text is '8598', the text message is identified as a coupon request message to transmit a coupon to the service provider.

When the transmitted text is a coupon request message, the short message controller 17 recognizes a text included in a body of the text message as a search word. At this time, the recognition of the search word is divided into a plurality of search terms by dividing the words included in the body content by a predetermined identification code.

That is, for example, if the content of the text message body is "tours, bread, gongdong", and the identification code is ',', the short message controller 17 may search the search word of the coupon request message 'tours,' It is recognized as 'bread' and 'gungdong'.

The short message controller 17 compares index words stored in the data storage 18 to be described later, and searches for a coupon including all of the search terms in the index words. The retrieved coupon is transmitted to the reply number included in the coupon request message through the exchange 13.

In this case, the short message controller 17 reads the location registration register 15 to determine the location of the portable terminals 20 and 20 'to which the coupon is to be transmitted, and the portable terminal 20 to which the coupon is to be transmitted. 20 ') may be selected and sent to the nearest service provider of the coupon.

 And according to another embodiment of the present invention, if there are a plurality of the searched coupons, the short message controller 17 generates a coupon information message to organize the searched coupons in a list form to the originating terminal of the coupon request message ( You can major in 20.

Here, the coupon information message includes a service provider name of each coupon and an index word stored for the coupons in the data storage 18. The reason for writing the coupon information message including the index word is to allow the user to receive the coupon information message and input the correct search word again to send the coupon request message so as to download the coupon of the desired company.

Accordingly, in order to reduce the message capacity, the coupon information message may be created by including only the index words except for the same index word as the search word included in the first coupon request message sent.

Meanwhile, the short message controller 17 includes a data storage unit 18 that stores a coupon provided from a coupon provider, a company name of the coupon, an index word requested by the coupon provider for the coupon, and location information of a company using the coupon. Connected.

The central server 10 includes a modem 19 for connecting the central server 10 to the Internet. As described above, the modem 19 connects the central server 10 to the Internet network so that the external PC 50 can access the central server 10.

This is a part which allows the coupon request message to be written on the PC 50 and transmitted to the central server 10 using the Internet, rather than being created and transmitted by the portable terminal 20.

Further, the modem 19 is directly connected to the PC (50) to the central server 10, using the coupon sending system provided by the central server 10 to find the desired coupon directly to the desired portable terminal This is the part to transmit to (20,20 ').

And, as shown, the central server 10 is connected to the mobile telephone network 40 of another communication provider, so that the coupon can be transmitted when the terminal of the coupon is subscribed to a third party.

Hereinafter, a method of transmitting a mobile coupon according to the present invention will be described in detail with the accompanying drawings.

As shown in Figure 2, the mobile coupon transmission method according to a specific embodiment of the present invention, first, begins by creating a coupon request message in the portable terminal (20) (S100).

The coupon request message refers to a text inputted by a service provider as a transmission number on a short message service (SMS) currently being used, rather than another type of message.

That is, when the transmission number of a general text message is entered as '8598' (assuming that the preset number is '8598' as described above), the text message becomes a coupon request message.

   When the created coupon request message is transmitted (S110), the central server 10 of the mobile communication network receives the message (S120). The received message is transmitted to the short message controller 17, and the short message controller 17 determines whether the text message is a coupon request message (S130).

In this case, if the transmission number of the text message is a predetermined specific number, the determination method determines that the message is not a coupon request message or a general text message.

If the transmitted text message is not a coupon request message, the text message is transmitted like a normal text message (S140).

However, if the text message is a coupon request message, the corresponding coupon is searched by comparing the body content of the coupon request message with the contents stored in the data storage unit 18 (S150).

In the search method of the corresponding coupon, as described above, the contents of the coupon request message body are divided into predetermined identification codes and recognized as search terms, respectively, and the coupons having all the search terms are searched for a coupon.

In this case, in searching for the corresponding coupon, a coupon close to the positions of the receiving terminals 20 and 20 'may be preferentially provided using the location information of the receiving terminals 20 and 20' to receive the coupon. .

That is, in the search method of the corresponding coupon, as shown in detail in FIG. 3, first, a coupon having index information (index word) including a search word in a coupon request message is searched for (S152).

The terminal 20, 20 ′ to receive the coupon is searched for (S154). At this time, the positions of the receiving terminals 20 and 20 'can be searched by searching the above-described position registration register 15. Alternatively, when the terminals 20 and 20 'are equipped with a GPS receiving module, the terminal 20 and 20' may be searched by receiving the location information measured by the GPS from the terminals 20 and 20 'and by measuring the strength of the radio signal. It may also be calculated by triangulation.

That is, there is a method of using the recording of the location registration register as a representative method, but various well-known terminal location calculation methods may be applied.

After the location of the receiving terminal 20, 20 'is searched, the company is located at the shortest distance from the location of the terminal 20,20' from the location information of the coupon service company stored in the data storage 18. Search for the coupon and select the coupon as the corresponding coupon (S156).

Alternatively, as shown in FIG. 4, after performing the steps 152 and 154, the position of the terminal 20, 20 ′ is determined from the location information of the coupon service company stored in the data storage 18. A plurality of coupons (N) where a service provider is located at a short distance may be searched to select all of the coupons as corresponding coupons (S158).

Thereafter, the central server 10 transmits the corresponding coupon (s) to the terminal 20, 20 'number described in the received number of the coupon request message (S170).

Then, the shipment details (download information) of the coupon are stored in the data storage unit 18 (S180).

The shipment history refers to information such as the number of dispatches for the coupons that have been sent, the reception location, and the subscriber information (stored in the HLR) of the terminals 20 and 20 'that have received the coupons.

This is to allow a service provider (communication company) according to the present invention to be provided as a material informing each coupon provider how much their coupons were provided in what form.

In addition, the portable terminals 20 and 20 'that receive the coupon store the coupon (S190, S195).

In this case, the terminal 20 for creating and sending the coupon request message may be a portable terminal 20 or a PC 50 connected to the Internet. That is, the coupon request message may be created and transmitted using the PC 50.

In addition, the portable terminal receiving the coupon may be the same terminal 20 as the terminal 20 which has created the coupon request message, or may be another portable terminal 20 '.

In other words, you can receive a coupon using your own mobile phone, you can send a coupon to another person using your mobile phone, you can send a coupon to yourself or another person's mobile phone using a PC.

On the other hand, the mobile coupon transmission method according to another embodiment of the present invention, as shown in Figure 5, has a flow similar to the mobile coupon transmission method according to a specific embodiment of the present invention.

However, in the mobile coupon transmission method according to another embodiment of the present invention, when there are a plurality of searched coupons, a plurality of mobile coupons are selected so that the user can select and receive the optimal one again. A coupon information message containing information about coupons is generated to transmit the coupon information message.

Referring to FIG. 5, on the other hand, the mobile coupon transmission method according to another embodiment of the present invention is the same as the steps 100 through 150 of the mobile coupon transmission method according to a specific embodiment of the present invention. To step 250.

In operation S260, it is determined whether there are a plurality of corresponding coupons found in operation 250.

As a result of the determination in step 260, when there are a plurality of corresponding coupons, a coupon information message containing information of the corresponding coupons is generated (S262).

The coupon information message includes a service company name of the corresponding coupon, index words and location information assigned to each coupon.

In this case, the index word may be an index word except for an index word overlapping the search word included in the initial coupon request message.

That is, as described above, the coupon information message is for the user to receive it, so that the user can select the desired coupon to be sent again, the user sees the coupon information message all the index words of the desired company The coupon request message including the message may be sent again to receive one coupon.

To this end, there should not be more than one coupon for which the index terms all match. Therefore, at least one index word of each coupon is preferably set differently.

After the coupon information message is written, the coupon information message is transmitted to the receiving terminals 20 and 20 '(S264).

Then, the contents of the transmitted coupon information message are stored in the data storage unit 18 (S280).

In addition, the terminal (20, 20 ') receiving the coupon information message stores the received coupon information message (S266, S295).

On the other hand, if it is determined that the corresponding coupon is one, step 260, steps 270 to 295 are performed in the same manner as steps 170 to 195 of the method for transmitting a mobile coupon according to a specific embodiment of the present invention. do.
