Abstract

A method for maintaining relations between messages in interactive SMS(Short Message Service) is provided to offer a survey research system convenient for both a survey research company and respondents by enabling an interactive SMS user to simultaneously transmit a plurality of questionnaire messages through one subscriber destination number and to easily confirm for which questionnaire a received reply message is. An SMS questioner creates a questionnaire message(S10) and sends it to a questioner-side communication company(S20). The questioner-side communication company transmits the questionnaire message to a respondent-side communication company, including a respondent's destination number, a nominal callback number, and the SMS questioner's origination number(S30). The respondent-side communication company delivers the questionnaire message to the respondent's terminal together with the nominal callback number and the SMS questioner's origination number(S40). Confirming the questionnaire message, the respondent sends a reply message to the respondent-side communication company after selecting a response for the questionnaire message(S50,S60). In this case, the reply message is transferred together a nominal destination number and the respondent's callback number. The respondent-side communication company checks the prefix of the nominal destination number contained in the reply message, extracts an actual questioner destination number, executes routing on the basis of the extracted questioner destination number, and forwards the reply message to the questioner-side communication company(S70). In the same manner, the questioner-side communication company checks the prefix of the nominal destination number contained in the reply message, extracts the actual questioner destination number, executes routing on the basis of the extracted questioner destination number, and delivers the reply message to the SMS questioner(S80).

The present invention relates to a method for maintaining a relationship between messages in a two-way SMS, and in particular, when a user of a two-way SMS service simultaneously transmits a plurality of questionnaires using the SMS and receives a response message for the questionnaire, the response message corresponds to a questionnaire. The present invention relates to a method of maintaining a relationship between messages in a two-way SMS so that the response can be easily extracted.

As is well known, the short message service (SMS) is a short message service that can send and receive short messages between mobile subscribers. When a digital mobile subscriber sends a short sentence to another mobile subscriber in Korean or English, Messages can be received via data communication networks or the Internet. Although SMS has a limited number of words, unlike e-mail, contents are delivered at the same time as when sent. After inputting a message on the phone, the SMS is designated by the phone number of the recipient. In recent years, its use has diversified into marketing, customer care, financial services, and simple surveys.

When conducting a survey through such SMS, the data that can be sent in one copy is limited to 80 bytes (40 Korean characters, 80 English characters). It is virtually impossible, and accordingly, in order to perform a questionnaire consisting of a plurality of items with one SMS called number, each questionnaire has to be divided and transmitted.

However, even in this case, a very cumbersome procedure is required for both the questioner and the respondent to distinguish each question. In other words, when an SMS subscriber (hereinafter referred to as a 'queryer') who has been assigned an arbitrary SMS destination number conducts a survey on Question 1 and Question 2 together, the respondent may classify the response message into Question 1 and Question 2 In addition to the response contents, the keywords to classify the question 1 and the question 2 should be written in the response message, and the SMS interrogator had to go through the cumbersome work procedure to extract these keywords from the response message contents.

In consideration of this hassle, when a questionnaire wants to conduct a survey consisting of a plurality of questionnaires, it is inevitable that a different SMS forwarding number must be used for each question with a plurality of SMS forwarding numbers preassigned. There was a problem that called party allocation cost is required.

Furthermore, in an environment such as a call center where one SMS called number is shared by multiple users, a plurality of agents simultaneously perform an SMS conversation in the form of a text consultation in the form of a conversation (repeat exchange of questions and responses) using SMS. In the case of proceeding, there is a problem in that the use of such a service is restricted because it is impossible to determine which agent the response from any customer is.

The present invention has been made to solve the above-mentioned problem, and when a two-way SMS service user simultaneously transmits a plurality of questionnaires using SMS and receives a response message for a questionnaire, the corresponding response message responds to a questionnaire. It is an object of the present invention to provide a method of maintaining a relationship between messages in a two-way SMS so that recognition can be easily extracted.

Another object of the present invention, even in the case of a plurality of agents proceed SMS conversation at the same time in a text format in the form of a conversation between the customer and the agent using the SMS in an environment such as a call center to share a single SMS called number It is to provide a method of maintaining the relationship between messages in a two-way SMS so that it is easy to extract to which agent the message from the customer.

Method for maintaining the relationship between messages in the two-way SMS according to an aspect of the present invention for achieving the above object is a survey respondent assigned a random subscriber called number via a wireless or wired SMS carrier or MO service provider The questionnaire is performed by the survey interrogator in a state of being connected to a wireless SMS terminal or a wired SMS terminal, and when a survey message consisting of SMS is inserted, a nominal reply number is inserted after inserting a survey ID defining the question after the subscriber's called number. Transmitting the questionnaire ID after the subscriber's called number from the nominal reply number of the step of transmitting to the wireless or wired SMS terminal which is the survey respondent and the response message from the wireless or wired SMS terminal which is the survey respondent; Including associating relationships between responses Is done.

In the above-described configuration, the wireless or wired SMS provider or the MO service provider checks the prefix of the nominal reply number for the response message from the survey respondents, and the type and corresponding number system of the corresponding SMS service of the subscriber's called number. After confirming the extract the subscriber's called party number of the actual survey query, and performs the routing to the survey query by the extracted subscriber called number, and transmits without changing the nominal reply number.

On the other hand, the method of maintaining the relationship between messages in the two-way SMS according to another aspect of the present invention is a wireless SMS terminal or a wired SMS terminal where the call center operator assigned an arbitrary subscriber number is a customer via a wireless or wired SMS operator or a MO service provider. It is performed by the call center operator in the state connected with the customer, when sending an SMS conversation message to the customer after inserting the agent ID to define the agent of the conversation message after the subscriber called number to the nominal reply number to the wireless or Transmitting the agent ID after the subscriber's called number from the nominal reply number for the SMS conversation message from the wireless or wired SMS terminal, which is the customer, to associate the conversation message with the corresponding agent and the customer. Including the steps of verifying the relationship All.

In the above configuration, the wireless or wired SMS operator or the MO service operator checks the prefix of the nominal reply number for the conversation message from the call center operator to determine the type of the corresponding SMS service of the subscriber's called number and the corresponding number system. After confirmation, the called party number of the actual call center operator is extracted, and the routing is performed to the call center operator according to the extracted subscriber called number, but is transmitted without changing the nominal reply number.

Hereinafter, a method of maintaining a relationship between messages in a two-way SMS according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings, which will be briefly described with reference to an address used to transmit and receive an SMS message. do.

In general, an address value used for sending and receiving an SMS message is largely composed of a calling number, a called number, and a reply number. Here, the caller ID refers to a subscriber number assigned to an SMS user by an SMS service provider, and the caller ID refers to a subscriber number of an SMS receiver or an SMS MO (Mobile Originate) called number. In addition to the calling and called numbers, the SMS has a separate address field called a reply number that allows the SMS sender to freely specify an address to which the SMS response is sent. That is, when the user selects a menu item 'Reply' or 'Reply' in the SMS terminal, the terminal basically fills the called party number field of the reply message with the reply number of the received message.

The present invention focuses on the use of such an SMS reply number, and the ID (Request Identifier) character number (hereinafter referred to as 'question ID') that can define the question in the reply number when sending the SMS for a survey By inserting and extracting the questionnaire ID from the response message, it is easy to find the correlation between the questionnaire and the response. Furthermore, in the interactive text counseling service, by using the questionnaire ID as the counselor ID for identifying the counselor, the agent information in conversation can be extracted from the received response message.

1 is a network diagram illustrating a method for maintaining a relationship between messages in a bidirectional SMS according to the present invention. As shown in FIG. 1, a network configuration in which a method for maintaining a relationship between messages in a two-way SMS of the present invention is implemented is largely composed of an SMS interrogator 400 consisting of various MO service subscribers or intelligent SMS service subscribers. Or via the wired SMS provider 300 or in addition to the wireless SMS terminal 110 or the wired SMS terminal 120 which is the SMS responder 100 via the MO service provider 250.

In the above configuration, the wireless SMS service provider 200 and the wired SMS service provider 300 is a message switch that is responsible for message transfer between the SMS terminals or between the SMS terminal and the SMSG (Short Message Service Gateway), respectively, for the SMS user. Short message service centers (SMSCs) that perform functions such as authentication and billing, and SMSGs 210 and 310 which are message switches that are responsible for message transfer between SMSCs and SMS clients or between SMSCs and other SMSGs are provided.

Next, the intelligent network of the wired SMS provider 300 is a network in which a centralized service control function is added to the communication network so that a new additional service can be easily added to the telephone communication network. , 1577,... The telephone number with the prefix of the network corresponds to the intelligent network service. The intelligent network is provided with a service control point (SCP), which is a system in charge of service control, and a service control point (SMS) 320, which is a system in charge of service management such as database construction, billing, and statistics required for intelligent network service.

On the other hand, when the queryer 400 passes through the MO service provider 250, since the MO service provider 250 provides the SMSG function, SMSG may not be required, but the wireless or wired SMS service provider 200, 300 In the case of direct connection with SMS), the SMSG 410 is required, and in addition, the query / statistics server 420 and the database 430 are provided. The database 430 includes a survey contents DB 432 storing a plurality of surveys used in the survey and a survey ID for identifying the survey, a called number DB 434 storing a called number for a plurality of respondents, and a survey. The response statistics DB 436 may store various statistics about the response. The query / statistics server 420 extracts a questionnaire ID from each questionnaire stored in the questionnaire content DB 432 and adds it after its SMS forwarding number as a nominal reply number, and responds to the destination number of multiple respondents stored in the forwarding number DB. SMS sending module for sending the survey to SMS, SMS receiving module 426 for receiving a response to the questionnaire from the respondent, and survey ID for extracting the questionnaire ID from the nominal called number (to be described later) included in the response message received from the responder. It may include the extraction module 424 and the response statistics processing module 428 for automatically extracting and statistically processing the response message for the questionnaire.

On the other hand, MO (Mobile Origination) service refers to a service that allows you to send SMS to the web from the wireless or wired SMS terminal and also receive a response to the SMS, such MO service is a quiz or donation using the ARS currently made by phone It also allows you to replace SMS, call center tasks and complaints tasks. For example, the recently popular terrestrial broadcast ARS quiz allows you to send the correct answer by SMS instead of making a phone call and submitting a quiz.In government offices, you can receive related complaints by SMS instead of accepting complaints by phone. Etc. can handle call center work. In addition, it can be used for various purposes such as Internet surveys.

2 is a flowchart illustrating a method for maintaining a relationship between messages in a bidirectional SMS according to the present invention. As shown in FIG. 2, in step S10, the interrogator A first constructs a questionnaire message, and then in step S20, the questionnaire message thus configured is transmitted to the interrogator-side communication company. For example, an SMS message for a survey, for example, " If the answer is 1, if it is wrong, please answer 2 ", the reply number (hereinafter referred to as 'nominal reply number') field is configured to include two pieces of information as shown in Table 1 below. One is the called party information (the SMS subscriber number or the SMS MO called number of the queryer) of the interrogator A who sent the questionnaire message, and the other is the survey ID information that can distinguish the questionnaire. The second survey ID information should be added after the first interrogator called number, and the survey ID information used at this time is preferably composed of numbers from 0 to 9 used in the telephone number.

Nominal Reply Number = [Question Caller ID] + [Survey ID]

For example, if the called party A's called number is '1588-1234' and the survey ID is '5678', the nominal reply number is "158812345678." The rest of the operations and procedures of the transmission system) are exactly the same as the configuration and transmission procedure of a normal SMS message.

2 again, the interrogator side communication company transmits the questionnaire message together with the called party number information, the nominal reply number information of the responder B, and the calling party number information of the interrogator A to the responder side communication company in step S30. The communication company performs routing to the called party number of the responder B again in step S40 to send the questionnaire message along with the nominal reply number information and the calling party number information of the responder B to the SMS terminal of the responder B. send.

Next, in step S50, after the responder B confirms the questionnaire message, the responder B transmits his or her own selected response message. The procedure for creating and transmitting the response message will be exactly the same as when replying the general SMS message. That is, the respondent B receiving the survey message selects a "reply" or "reply" menu in his or her SMS terminal, where the called party number field of the response message is the same as in the case of replying to another SMS message. It will have the nominal reply number value (Questioner's Calling Number + Questionnaire ID), and respondent B only selects "2" corresponding to the answer to the questionnaire, eg "wrong" and then selects Send. Just do it. Then, in step S60, the respondent's communication company together with the nominal reply number information as the called number information (hereinafter referred to as 'nominal called number' for convenience of explanation in the callee's procedure) and the reply number of the responder B The response message "2" is delivered.

Next, the responder's communication company checks the prefix of the nominal called party information in step S70 and checks the type of SMS service and the number system according to the corresponding SMS service. Routing is performed to the interrogator on the interrogator side, and the response message “2” is transmitted together with the nominal called number, the reply number of the responder B, and the caller number of the responder B.

Similarly, the interrogator on the inquiry side extracts the actual interrogator called number by checking the prefix of the nominal called number information in step S80 and confirms the type of SMS service and the number system according to the corresponding SMS service. Routing is performed to the interrogator A, and the response message "2" is transmitted along with the nominal called number, the responder B's reply number, and the responder B's caller ID information.

Finally, the queryer A checks his or her called number in the field as the nominal called number in step S90, and then extracts the number added after it, that is, the questionnaire ID, to automatically determine which questionnaire the response message received is for. After confirmation, necessary statistical processing is performed.

On the other hand, when looking at the response message routing (Routing) operation in the SMS network, SMSC and SMSG devices provided in the SMS network performs routing based on the prefix number prefix of the SMS message, the name of the response message sent by the responder (B) The called party number has the nominal reply number (query called party number + questionnaire ID) of the interrogator A, so that the called party prefix of the response message still matches the prefix of the called party called number.

Here, the message routing procedure and operation to be performed by SMS service providers according to several commercially available SMS MO service types will be described in detail.

(1) 200 MO service

MO call number 200 is composed of a seven-digit number system, and most of the response message to the subscriber (inquirer in the present invention) in the form of direct interworking with the mobile communication provider without a separate MO service provider. Therefore, when the nominal called number prefix of the response message is 200, the mobile communication service provider performs routing to the interrogator using the first 7 digits of the MO called number as the real called number, so that no loss of the survey ID information occurs. Send the message to the queryer without changing the number.

(2) MO service 013

MO destination number 013 is composed of an 11-digit number system, most of the response message to the subscriber (inquirer in the present invention) directly or indirectly via a specific MO service provider. Therefore, if the nominal called number prefix is 013, the mobile service provider performs routing to a specific MO service provider using the first 11 digit MO called number as the actual called number. In order to prevent this from happening, a response message is sent to the MO service provider without changing the nominal called number. And the MO service provider who receives it also decides the called subscriber (the questioner) with the specified first 11 digits of the real calling number as in the operation of the mobile communication service provider. To).

(3) intelligent SMS service

Intelligent SMS refers to a two-way SMS service configured to send and receive SMS with a wired intelligent network phone number. The feature of this intelligent SMS service is that the message receiving number has a wired intelligent network telephone numbering system, the intelligent network telephone number translation process is performed during the message receiving process, and the call processing process is accompanied by a call processing process as in a phone call in the operation of delivering an SMS. . Therefore, the SMSC of the wireline provider receiving the intelligent SMS message from the sender of the message performs the translation process of the intelligent telephone number through the interworking of the intelligent network, which translates the intelligent telephone number into the actual called number Means a number having a general telephone number system in the form of "area code-station code-subscriber number" in which routing can be performed.

The detailed intelligent network phone number translation procedure performed by SMSC of fixed line operator is as follows. First, the SMSC of the wireline provider receiving the message checks whether the nominal called number field of the message has a prefix corresponding to the intelligent telephone number. If the nominal called number has an intelligent network prefix, only the pure intelligent network phone number (subscriber called number except the question ID) is extracted from all numbers in the nominal called number field. Next, the intelligent subscriber telephone number is extracted using the extracted intelligent network telephone number to extract the actual subscriber called number.

Here, as in other MO services, the SMSC of the wireline operator does not change the nominal called number for the SMS message itself. The real called number obtained through the intelligent network telephone number translation procedure is used to change the called number field of the response message. Rather, it is used as a called number for the originating call required in the intelligent SMS message transmission process. Naturally, if such intelligent SMS message delivery is performed via other SMSGs or SMSCs other than the destination SMSC, all SMSGs or SMSCs in the path will also forward the response message without changing the nominal called number. For example, if a mobile phone sends an SMS message to an intelligent SMS recipient, the mobile operator must send a response message to the wireline provider based on the prefix routing, and the nominal called number should not cause loss of survey ID information. Do not perform the change operation of.

The method of maintaining the relationship between messages in the two-way SMS of the present invention is not limited to the above-described embodiments, and can be modified in various ways within the scope of the technical idea of the present invention. For example, in applying the method of maintaining the relationship between the messages in the two-way SMS of the present invention to the survey, the survey is performed on one response group (A) and the other response group (B). Various applications may be possible, such as conducting a survey on survey 2.

On the other hand, by applying the questionnaire ID as the agent ID in an environment such as a call center where one SMS called number is shared by a number of agents, the customer and the agent use SMS to conduct a text consultation in the form of conversation (repeat and exchange of questions and responses). In this case, it is possible to automatically identify which agent the response message belongs to and deliver it to the counselor. In this case, the contents of the query / response server shown in FIG. 1 should be appropriately changed. For example, the survey ID extraction module is changed to the agent ID extraction module, while the response statistics processing module and the database may not be required. have. On the other hand, letters other than numbers may be used as the questionnaire ID or counselor ID.

According to the method of maintaining the relationship between messages in the two-way SMS of the present invention as described above, the survey provider using the two-way SMS service simultaneously transmits a plurality of questionnaires using the SMS through a single subscriber number, and for the questionnaire When receiving a response message, it is possible to easily extract the response to which question the response message is answered, thereby reducing the cost of assigning the subscriber's called number and achieving a corresponding effect. In other words, it is possible to provide a survey system that is convenient for both surveyors and respondents.

Furthermore, in an environment such as a call center, the questionnaire ID is applied as an agent ID to automatically determine which agent the response message is from when the customer and the agent conduct a text consultation in the form of conversation (repeat and exchange of questions and answers) using SMS. Because it can be confirmed and delivered to the counselor, it is possible to efficiently support the conversation with multiple counselors and customers while reducing the cost of assigning the subscriber's called number.
