Abstract

A collect call permission service system using SMS(Short Message Service) and a method thereof are provided to induce a callee to make a call to a caller and form a smooth call connection between the caller and the callee by transmitting a short message to inform the callee that the fee for this phone call will be paid by the caller, in case there is no response from the callee for the caller's call request. If a caller inputs a callee's phone number and executes a primary call request to a call processing server(S100), the call processing server forwards the request to the callee(S110). If the callee doesn't respond to the primary call request, the call processing server transmits the information generated for the primary call request to a database server so that the generated information can be stored(S130,S140). Then the call processing server transmits SMS forwarding request information, including the caller's phone number, the callee's phone number, a callback number, and a collect call guidance message, to an SMS server and requests the SMS server to send a short message to the callee(S150). The SMS server, receiving the SMS forwarding request, creates a short message, which contains the information that the fee for this phone call will be paid by the caller, on the basis of the received information. Then the SMS sends the created short message to the callee(S160).

The present invention relates to a system for receiving incoming calls and a service method using a short message service (SMS). When the called party does not answer a call request from a caller, the call charge for the call is borne by the caller. The present invention relates to an incoming billing call allowance service system and a service method using a short message service (SMS), which allows a called party to call a sender by sending an SMS message to a called party.

With the popularization of mobile communication, providers of mobile communication and mobile phones are trying to provide more various services to users. Therefore, in addition to simple call connection through mobile communication system, information service, e-mail, Various additional services such as web surfing are being made.

The handset is also miniaturized and lightened in the terminal itself, and in terms of functionality, it is maximizing user convenience by adding and improving additional functions such as electronic organizer, alarm, and clock in addition to functions for call service.

If a new function, which is organically combined with other functions of such a mobile phone or an additional service of mobile communication, is added to the mobile phone, it will be able to supply high quality service to the user.

Short Message Service (SMS) is a two-way service that can send and receive data of relatively short length (usually 80 to 160 bytes) between mobile communication terminals regardless of the communication between mobile terminals. Unlike this, it is widely used due to the advantage that the contents are delivered to the receiver at the same time as the sender.

SMS basically sends a reply number and a message between mobile terminals, and also in the form of text, bank account inquiry, money transfer, exchange rate information, travel information, traffic information, weather forecast, leisure information, TV information, You can receive a variety of information such as news, stock information and advertisements.

On the other hand, in the mobile communication system, the billing system basically consists of a billing system in which the caller bears the call charge, and the incoming billing system is applied as an additional service.

Here, the called billing service is a special number rather than a general telephone number, that is, a service charge number and a called billing number, which are assigned to the subscribers of the service, so that the call charge of the incoming call is sent to the called party (service subscriber) instead of the caller (service user). The service to be added.

Conventionally, there are the following methods for making the callee's billing call.

First, by using the 080-xxxxxxx phone number, the user has to subscribe separately and receive the 080 number separately from the real number, and is mainly serviced for the enterprise because the call is processed for all calls regardless of the caller.

Second, as a service such as 08217 and 1633, the caller presses the 08217 + real caller number and talks with the called party for the first few seconds, and then decides whether to continue the call according to the caller's intention to pay the call charge.

In this case, the caller should not only feel the burden because the caller has to ask the caller about whether the caller is charged, and there is an inconvenience in that the caller needs to distinguish whether the caller wants to talk while paying the call charge.

The present invention has been made to solve the above problems, and when there is no caller's call response to the caller's first call request, the caller is responsible for the call charges of the call, so the caller receives an SMS message to contact the caller. The purpose of the present invention is to provide an incoming billing call allowance service system and a service method using a short message service (SMS) to transmit a call to the caller to induce the caller to make a smooth phone connection between the caller and the called party.

An embodiment of an incoming billing call allowance service system using an SMS of the present invention transmits a caller's first call request to a called party so that a telephone call connection is made, and there is no answer of the called party to the first call request. When the called party sends a second call request in response to the SMS message, when the called party sends a second message, the information generated during the first call request is compared with the information generated during the second call request. If there is no response from the called party to the first call request and the information generated in the first call request is transmitted from the call processing server, the information generated in the first call request is transmitted to the database. Storing information in the corresponding table and transmitting the generated information when the stored primary call request is requested to the call processing server according to the request of the call processing server. If there is no database server and no response from the called party to the primary call request, information including an incoming billing call guide message and an SMS answering phone number is transmitted from the call processing server, and the information is converted into an SMS message. And an IVR server for transmitting the announcement to the called party or the caller according to the decision whether to allow the second call request from the call processing server.

An embodiment of an incoming billing call acceptance service method using an SMS of the present invention includes a first step in which a caller performs a first call request to a called party, and when there is no response to the first call request from the called party, call processing. A second step in which the server transmits the information generated in the first call request to a database server, and the database server stores the information generated in the first call request in a corresponding table of a database; A third step of transmitting information including a billing call guide message and an SMS response telephone number to an SMS server, wherein the SMS server converts the information into an SMS message and transmits the information to the called party; and the called party responds to the SMS message. A fourth step of determining, by the call processing server, whether to allow the second call request when the second call request is made; And if the secondary call request is allowed, the call processing server transmits the secondary call request to the caller, thereby establishing a telephone connection between the caller and the called party.

Hereinafter, a method of allowing an incoming billing call using the SMS of the present invention will be described in detail with reference to FIGS. 1 and 2. 1 is a diagram schematically showing the configuration of a system for implementing an incoming billing call permission service using the SMS of the present invention.

As shown therein, a system for implementing an incoming billing call allowance service using the SMS of the present invention includes a caller 10, a called party 20, a wired / wireless telephone network and an internet network 30, a call processing server 40, a database. A server 50, a Short Message Service (SMS) server 60, and an Interactive Voice Response (IVR) server 70 are configured.

The caller 10 and the called party 20 not only provide a voice call function for performing a normal voice call through wired / wireless communication with different terminals, but also create a short message to be delivered using the provided text writing function. It is a terminal capable of transmitting a message prepared by a wired / wireless telephone network and an internet network 30.

That is, the caller 10 and the called party 20 may not only transmit and receive calls, such as a PC, a personal digital assistant (PDA), a mobile phone, a wired terminal, and a Voice over Internet Protocol (VoIP) connected to the wired / wireless telephone network and the Internet network 30. It is a terminal that can transmit and receive a short message.

The call processing server 40 receives the first call request from the caller 10 and transmits it to the called party 20. The call processing server 40 receives the call response of the called party 20 to the first call request. Send to 10).

Here, when the called party 20 does not respond to the first call request of the caller 10 because the caller 20 is busy or powered off, the call processing server 40 displays the information generated at the first call request. The data is sent to the database server 50 for storage.

Then, the call processing server 40 is the telephone number of the caller 10, the telephone number of the called party 20, the SMS response telephone number (that is, call back number), the non-answering reason of the called party 20, incoming Information about the billing call guide is transmitted to the SMS server 60.

In addition, the call processing server 40, upon receiving a call request (that is, a secondary call request) as a response to the SMS message from the called party 20, when the first call request stored in the database server 50 It is determined whether the call is allowed by comparing the generated information with the information generated in the second call request.

Here, when the call processing server 40 does not allow the call for the secondary call request, the caller server 40 transmits a message to the called party 20 that the service of the present invention is not available to the IVR server 70. Ask for it.

In addition, when the call processing server 40 allows the call for the second call request, the call processing server 40 transmits the second call request of the called party 20 to the caller 10, and transmits the call to the IVR server 70. Requests to send the announcement to the caller 10 that the service of the present invention is started.

The call processing server 40 may be a telephone network-based computer telephony integration (CTI) server, an intelligent network or VoIP-based soft switch, an application server, or the like.

If there is no response from the called party 20 in response to the primary call request, the database server 50 transmits the information generated during the primary call request, and stores the information in the corresponding table of the database. .

When the call processing server 40 requests to transmit the information generated when the first call request is stored, the call processing server 40 extracts the corresponding information from the corresponding table in the database and transmits the information to the call processing server 40. give.

SMS server 60 from the call processing server 40, the telephone number of the caller 10, the telephone number of the called party 20, the SMS response telephone number, the non-responsive reason of the called party 20, the call charge guide When the information about the message is transmitted, the information is converted into an SMS message including the called billing call guide message and the SMS response phone number and transmitted to the called party 20.

When the IVR server 70 receives the announcement announcement request from the call processing server 40, the IVR server 70 transmits the announcement announcement to the caller 10 or the called party 20.

2 is a diagram illustrating a process of performing an incoming billing call permission service method using an SMS of the present invention. As shown therein, the caller 10 connected to the wired / wireless telephone network or the wired / wireless internet network 30 performs the first call request to the call processing server 40 (step S100).

At this time, when the caller 10 subscribes to a communication company providing an incoming billing call allowance service using the SMS of the present invention, the caller requests a call to the called party number (for example, 0210002001) of the called party 20. If the caller 10 does not subscribe to the telecommunications company, the called party 20 calls the prefix 20 and the called party number (for example, 1677 + 0210002001) designated by the telecommunications company for the service. The call request will be performed.

That is, a caller 10 who subscribes to a telecommunication company that provides an incoming billing call allowance service using the SMS of the present invention accesses a web site designated by the telecommunication company through a wired / wireless internet network, moves to a corresponding web page, and then selects a corresponding menu. After selecting and starting the incoming billing call allowance service using SMS, the call to the destination number of the called party 20 to perform a call request.

In this case, the caller 10 may terminate the incoming billing call permission service using the SMS in the same manner as the method for initiating the incoming billing call permission service using the SMS.

In addition, the caller 10 who does not subscribe to a communication company providing an incoming billing call allowance service using the SMS of the present invention presses a prefix number designated by the communication company for this service, and then presses the called party number of the called party 20. Will execute the request.

In this case, the sender 10 has an advantage that the service can be used anytime and anywhere without a separate subscription procedure.

The call processing server 40 forwards the primary call request from the originator 10 to the called party 20 (step S 110).

Then, when there is a call response to the primary call request from the called party 20, the call processing server 40 delivers the call response of the called party 20 to the caller 10 to call each other A connection is made (step S 120).

If the called party 20 does not respond to the primary call request for reasons such as being on a call or powered off, the call processing server 40 may provide information generated during the primary call request, for example, the caller. Send the telephone number of (10), the telephone number of the called party 20, the call request time, the reason for the non-answer of the called party 20, etc. to the database server 50 to store the information (step) S 130).

When the information, such as the telephone number of the caller 10, the telephone number of the called party 20, the call request time, the reason for no answer of the called party 20, is transmitted from the call processing server 40, the database server 50 ) Stores the information in a corresponding table of the database (step S 140).

In addition, the call processing server 40 transmits the information regarding the telephone number of the caller 10, the telephone number of the called party 20, the SMS response phone number, and the incoming call prompting message to the SMS server 60 to send the called party. Request 20 to send the SMS message (step S 150).

Upon receiving the SMS message sending request from the call processing server 40, the SMS server 60 sends the information received from the call processing server 40 to the caller 10's telephone number and the SMS response telephone number (i.e. , A callback number), and converts it into an SMS message including the incoming billing call guide message and transmits it to the called party 20 (step S 160).

Here, the incoming billing call guide message includes information indicating that the subsequent call charges will be borne by the caller 10 when the called party 20 responds to the SMS message.

For example, the call forwarding message "02-1000-2000 called but not connected because the call was missed. The call charge for this call is charged to 02-1000-2000. Click "."

When the called party 20 receives the SMS message and presses a call button or calls the SMS answering phone number included in the SMS message, the second call request is received by the call processing server 40 (step S 170). ).

When the secondary call request is received, the call processing server 40 checks whether the secondary call request is a call request as a response to the SMS message, and then, when the primary call request is made to the database server 50. A request is made to transmit the generated information (step S 180).

The call processing server 40 may check whether the secondary call request is a call request as a response to the SMS text message through the SMS response phone number included in the secondary call request.

That is, in general, the SMS response telephone number is composed of a prefix number specified by a communication company and the telephone number of the caller 10, and the call processing server 40 recognizes the prefix number included in the SMS response telephone number, It may be confirmed whether the call request is a call request as a response to the SMS text message.

As such, when it is confirmed that the secondary call request is a call request as a response to the SMS text message, the call processing server 40 determines the database server 50 to determine whether to allow the secondary call request. Request to transmit the information generated in the first call request stored in the).

When the database server 50 receives a request for transmission of information generated when the first call request is received from the call processing server 40, the database server 50 extracts information stored in a corresponding table of the database to the call processing server 40. Transmit it (step S 190).

When the information generated in the first call request is transmitted from the database server 50, the call processing server 40 compares the information generated in the first call request with the information generated in the second call request and the second call request. It is determined whether to allow the call request (step S200).

When the called party 20 makes a call request, it is common for the called party 20 to pay the call charge, but in the present invention, the caller 10 who made the first call request is borne by the called party 20. Therefore, the user who made the second call request needs to confirm whether the caller 10 who made the first call request is the other party who is willing to bear the call charge.

Accordingly, the call processing server 40 compares the caller's telephone number and the called party's telephone number in the information generated during the first call request and the information generated during the second call request, respectively, and compares the call request time with the secondary call. Determine whether to allow the request.

That is, the calling party telephone number at the first call request and the called party telephone number at the second call request are the same, and the called party telephone number at the first call request and the calling party telephone number at the second call request are the same. If the time difference between the first call request time and the second call request time is not large, the second call request is allowed.

In this case, when the originator 10 making the first call request attempts to pay a call fee only for the first call request from the called party 20, the call request from the called party 20 may be the first. The first or second call is allowed, and the second or third call is not allowed.

As a result of the determination by the call processing server 40, when the second call request is disallowed. For example, when the called party's telephone number at the time of the first call request and the calling party's telephone number at the second call request do not match. Or, if the second call request is not the first from the called party 20, it requests to transmit the announcement to the IVR server 70 (step S 210).

That is, when it is determined in step S 200 that the second call request cannot be accepted, the call processing server 40 informs the called party 20 that the service cannot be used. The IVR server 70 makes a request.

When the IVR server 70 receives the announcement message transmission request, the IVR server 70 transmits the announcement to the called party 20 indicating that the service cannot be used (step S 220).

As a result of the determination of step S 200, when the secondary call request is allowed, the call processing server 40 transmits the secondary call request to the caller 10 (step S 230), and the IVR server ( In step 70, a request is made to transmit the announcement to the caller 10 to start the service (step S240).

When the IVR server 70 receives the announcement message transmission request from the call processing server 40, the IVR server 70 transmits the announcement message including the content of starting the service to the caller 10 (step S 250).

That is, when the caller 10 responds to the secondary call request, the IVR server 70 transmits an announcement to the caller 10 that a call charge is borne by the caller 10. .

The caller 10 responds to the call processing server 40 in response to the second call request (step S260), and the call processing server 40 delivers the call to the called party 20 to each other. The telephone connection is made (step S 270).

On the other hand, while the present invention has been shown and described with respect to specific preferred embodiments, various modifications and variations of the present invention without departing from the spirit or field of the invention provided by the claims below It will be readily apparent to one of ordinary skill in the art that it can be used.

As described above, according to the present invention, when there is no call answer by the called party to the caller's initial call request, the call charges of the call are borne by the caller, so that the called party sends an SMS message to the called party to contact the caller. By instructing the caller to call, a smooth telephone connection can be made between the caller and the called party.

That is, from the caller's point of view, if there is no call response from the called party when the first call is requested, the caller may wait for the caller's call request, thereby eliminating the inconvenience of repeatedly requesting a call. In this case, since there is no objection that the caller bears the call charges, the call is actively answered to the second call request from the called party, thereby making a smooth telephone connection with each other.

In the case of the called party, even if a call request is made in response to the SMS message, the caller does not have to pay the call fee, so there will be no hesitation in making the second call request.
