Description

Remote Education System {A Remote Education System}

The present invention relates to a distance learning system using a telephone and the Internet. More particularly, the present invention provides an interactive distance learning service using a computer telephony integration (CTI) server and an internet server, and provides data generated from the distance learning service to a CTI server. And a remote learning system that allows the Internet server and the Internet server to share in part.

In the conventional distance education method, first, education broadcasting by radio waves or cables can be given. This is a way to educate on TV at a given time. Next, the distance learning method using video. This is how instructors and students in the two classrooms equipped with the video conferencing system conduct education while watching their faces and screens through videos with limited educational content. Finally, there is a distance learning method using a general network, which is an image and graphic on the fly using a dedicated video telephone system where data is shared by two users connected over a local area network (LAN) or a wide area network (WAN). It is a training method of sending and receiving data. In addition, the distance education method using the Internet, which can provide data such as moving images and voices anywhere in the world, and special fields such as language education, are provided by the instructor and the customer by telephone. There is a distance learning method.

First of all, the remote education method using the Internet will be described as follows. 1 relates to a method of distance education on the Internet using the Internet World Wide Web (WWW) regulations and related technologies on computers and networks. (Patent Publication 1998-28669)

This method is performed by the terminal apparatus 10, which is a means for searching the World Wide Web (WWW) on the general Internet, and the server apparatus 30 which transmits the searched data. The terminal apparatus 10 includes an input unit 12; And interface unit 14 for outputting the input content to the device is connected. The input unit 12 includes a keyboard and a mouse for inputting various data. In addition, the terminal device 10 constitutes an operating system 16 connected to the output of the interface unit 14 and the Internet protocol unit 20 operating thereby. The operating system 16 causes each device to operate such that the corresponding device processes the content input through the interface unit 14. The Internet protocol unit 20 refers to all protocols used on the Internet, and is required to receive a service through the Internet. The terminal device 10 is operated by the operating system 16 and includes a browser 22 capable of connecting to the Internet by the Internet protocol unit 20. The browser 22 searches for all documents on the Internet and displays the contents of the documents on the screen for the user to view. The terminal device 10 has a connection unit 18 connected between the interface unit 14 and the Internet and an output unit 24 connected to the interface unit 14. The connection part 18 is provided with a modem, a network adapter, etc. which were connected to the Internet network. The output unit 24 includes various devices such as a monitor to display the contents searched by the browser 22.

On the other hand, the server device 30 operates and is configured like the connection unit 18, the interface unit 14 and the operating system 16, and the Internet protocol unit 20 of the terminal device. That is, the server device 30 includes a connection portion 32 connected to the Internet and an interface portion 34 for outputting the input contents to the corresponding device. In addition, the apparatus includes an operating system 36 and an internet protocol unit 38 for operating each apparatus so that the apparatus processes the contents input through the interface unit 34. The server device 30 includes a WWW server unit 40 that is operated by the operating system 36 and operates on the Internet protocol unit 38. The WWW server unit 40 transmits the data requested by the browser 22 according to the HyperText Transfer Protocol (HTTP). The CGI program unit 42 is connected to the server device 30 between the WWW server unit 40 and the database management unit 44. The CGI program unit 42 operates by the operating system 36 and operates while exchanging data with the WWW server unit 40. The CGI program unit 42 provides an educational program for the user to learn based on the function of the CGI, and analyzes the learned contents. The Common Gateway Interface (CGI) not only provides a moving picture but also allows a user and a server to communicate with each other through a browser 22. In addition, the database management unit 44 is connected to the server device 30 between the CGI program unit 42 and the database unit 46. The database manager 44 operates by the operating system 36 and outputs data necessary for the CGI program unit 42 to operate with reference to the database 46. The apparatus has a database section 46 connected to a database manager section 44. The database unit 46 outputs data required by the database manager 44 or stores data input through the database manager 44.

As described above, the remote education method using the Internet is a one-way distance education system that simply receives data stored in a database using a customer terminal and a web server, and stores data input by the customer using a terminal in a database. One-sided training by the operator has the disadvantage of lowering the educational effect. In addition, in the case of language education, it is possible to listen to voice-recorded conversations in advance (L / C) or text-based (R / C), which does not go beyond the scope of existing book and tape-based education methods without interactive language education functions. It is true.

On the other hand, traditional language training by phone is a method where the instructor calls the member directly or the customer calls the instructor directly. There is an excessive problem. In addition, since it is a simple telephone training, it is difficult to manage information of customers and lecturers, and there is a problem in that the training effect is reduced by only training.

In addition, the conventional video communication education through the video is implemented as a video recording by mainly one-way, which has a problem that the education effect is halved as well.

An object of the present invention is to improve the above-mentioned problems, by using a CTI server, the customer and the instructor can perform a reliable and convenient remote telephone training with each other and at the same time can send and receive various data required by the customer and the instructor using the Internet server. The purpose is to provide an interactive distance education system.

Another object of the present invention is to provide a remote education system that can provide a satisfactory service to customers and instructors by systematically managing various data generated during the mutual training between the customer and the instructor by the CRM program.

Still another object of the present invention is to provide a remote education system that can provide real-time interactive education service and video communication education service instead of one-way using a stable PSTN network and Internet network.

FIG. 3 is a flow chart of the distance learning system according to the present invention. The distance learning flow through the Internet server 100 and the distance through the CTI server 200 will be described. It is divided into educational flows.

The customer first accesses the Internet through an Internet service provider (ISP) via his computer (401), and then, for example, the web address of the distance learning system via a web browser of MS-Explorer 5.0 or higher or Netscape 4.0 or higher (eduone. net). The web server transmits a login form for inputting an ID and password to the client or a homepage including a login field to authenticate whether the client to be accessed is an effective user. When the customer enters the ID and password in the login field, and compares the password for each ID stored in advance to complete the user authentication (402). At this time, the customer may enter the authentication number (pin number) to access the CTI server in both the ID and password to perform effective user authentication. Of course, the effective user authentication is possible under the assumption that the customer completes the membership registration in advance and the ID and password are given to the customer and the information is stored in the database. In general, such effective user authentication is generally performed in the operating system, but when a large number of members is performed in a separate authentication server for load balancing.

If the customer enters an incorrect ID or password, the member registration form is transmitted to the customer (403). In the above, when the non-subscription customer receives the homepage including the login field, the user may select the registration mode included in the homepage to directly perform the registration step (403).

Membership is divided into paid members, general members (free members), and paid members are divided into phone-to-phone members, distance education members and video communication members using the CTI server 200 and Internet phones. Paid members register general personal information. Among paid members, phone-to-phone members can register for classes, register for classes (10 minutes, 20 minutes, 30 minutes), and pay by using direct debit or credit card linked to financial institution CMS system. The distance education member pays the course fee using the course registration (applicable subject), the software for distance education, and the direct debit or credit card linked with the financial institution CMS system. ), Download video communication education software, and pay by using direct debit or credit card linked with financial institution CMS system. At this time, the course fee can also be paid by bank transfer, and the results of the course payment can be confirmed by inquiring on the Internet or by telephone to a financial institution, or can be confirmed by the method of confirming the deposit fact from the financial institution. The results of the confirmed tuition payments are recorded in the database, and the balance is managed while adding and subtracting the customer's additional deposit and the portion of the tuition fee. General (free) members should register only basic personal information, and in the case of instructors, enter personal lectures or other materials to promote themselves in addition to personal information.

As described above, when the customer inputs various personal information such as ID, password, name, address, and lecture and related data such as course registration time and subject to the Internet server 100, the Internet server 100 ) Transfers the input data to the database server and records the ID in the database for use in the login step 402. Customer ID (ID) is unique data and checks for duplicates using JavaScript when signing up. Such membership or effective user authentication is not only for customers but also for instructors, but membership should be selected as an instructor. In addition, ID and password loss management, membership information change, customer call history management, attendance, you can manage the call history of the instructor.

When the effective user authentication is completed by the above-described login 402, the homepage including a mode for selecting a paid member, a general (free) member, a non-member, or an instructor (foreigner) is transmitted, or a member of the customer when logging in. By searching the type, the homepage corresponding to the member classification can be transmitted. (404)

For general members, general service such as sample education service, humor / living English, travel information (Seoul travel agency partnership), chat, guest's / bulletin board, e-mail service can be used (710). The service contents of the general members are provided to other paid members and instructors by default.

In the case of instructors (foreigners), they can look up their lecture schedules or lecture history from the database, or create their own schedules and post them on the web page, and partially retrieve the information of the customers who are taking their lectures.

The following describes how a customer accesses the CTI server 200 to perform distance education. When the customer calls the CTI server 200, the CTI server requests a membership number input to the voice ARS service (501). After the customer enters the member number of the pin number, and compares the database with the recorded member number and performs a login to check whether the effective user (502). If the user is an effective user, the customer's member classification is a distance learning member or a phone-to-phone member (504), and the customer's tuition payment or balance status is notified to the customer (505). If the tuition fee is not paid or there is no balance, it is requested to pay the tuition fee and connected to a financial institution for direct transfer or credit card payment.

Phone-to-phone members connected through the Internet server, call ID registration, ID, password, reservation date, time data to schedule the call with the instructor, and stores the input data in the database to manage (610) Can be used. Phone-to-phone members connected through the CTI server can perform callback registration according to the ARS statement. These callback registrations may then notify the customer or instructor periodically or irregularly by e-mail or telephone, and may notify the customer when logging in through the CTI server or Internet server. Callback registration data associated with these customers or instructors is also handled by the CRM program. In the case of callback registration, it is important to increase service reliability for customers by first connecting the call with the instructor.

Video communication training members connected through an Internet server can use the callback registration function to enter ID (ID), password, reservation date and time data to make a video communication reservation with the instructor, and store and manage the input data in the database. Can be. These callback registrations may then notify the customer or instructor periodically or irregularly by e-mail or telephone, and may notify the customer when logging in through the CTI server or Internet server. Callback registration data associated with these customers or instructors is also handled by the CRM program.

When a phone-to-phone member connected through an internet server or a CTI server performs a call with a predetermined instructor, the instructor waits for a call when the instructor is on the phone and provides ARS or music (620). When the call waiting state continues for a predetermined time, callback registration 610 for pre-call reservation is made.

When a phone-to-phone member designates an instructor via the Internet, a web page with a lecture history or instructor information for a large number of instructors is sent to the customer for reference. Instructor-specific functions can be used to connect with (630). On the other hand, the customer using the CTI server can be specified by providing the voice of the lecturer, etc. to the customer according to the ARS statement. Instructors for these designated customers can also be recorded in the database, which can be provided later at customer login.

When a phone-to-phone member connected through an Internet server or CTI server enters a training time (date, time) for a telephone training with an instructor, the training time data is stored in a database, and the member and the instructor are called. Connected to the phone to conduct a call training (640). At this time, one minute before the training time may inform the end time, or may periodically guide the elapsed time. Such data related to call training is used to settle tuition fees and instructor fees of members, and all of them can be processed, analyzed, and processed by a CRM program to notify customers or instructors. Here, it is preferable to provide a reliability by preventing the unused tuition fee charged to the member by applying the disconnection function automatically after the end of time.

When a phone-to-phone member connected through an internet server wants to receive a study / training consulting, he / she selects a corresponding mode and provides a web page where various study / training information is posted (650). If you are a phone-to-phone member connected through a CTI server, you will be provided with study / training information by voice according to ARS.

Next, among the paid members connected through the Internet, the distance learning member and the video communication education member may receive the courses offered in the courses (810), the weekly education (820), the study abroad / training consulting (830). At this time, as a prerequisite for receiving these services, the member goes through the deposit or balance inquiry recorded in the database, and pays the tuition fee of the customer as well as the user authentication result when the customer logs in, rather than going through a separate inquiry step. Or it is desirable to send the balance status automatically. It is the role of the above-described CRM program to notify the result of data analysis on the customer. In addition, all data for each member, including customers and instructors, is processed, analyzed and processed by the CRM program. You can also record the history of your distance learning membership in a database and provide it at your next login or email it to you.

In the case of a distance education member connected through the CTI server 200, it is preferable to perform training that can be performed by voice, for example, education such as TOEIC L / C.

As described above, in the distance learning system of the present invention, data obtained through the Internet server is used when receiving the distance education service through the CTI server, and similarly, data obtained through the CTI server also has a convenient advantage of using the distance education service through the Internet. Has In other words, distance learning is carried out using the advantages of the Internet and telephone.
