&Quot; The distributed internet phone system "

Smartphone, Internet phone, VoIP, mVoIP, H.323

Due to the development of the Internet and the speed of the Internet, many companies such as SNS service providers are providing Internet phone services.

However, since existing service providers provide services through their own servers, the burden of service providers to invest in facilities such as server expansion due to the increase of subscribers is greatly increased, and the call quality There is a problem in that it is lowered.

The present invention relates to a distributed Internet service system in which a server is established in a group unit such as a home, a company, an institution, a group, and a region instead of a server of a specific company to communicate among the members, It is an invention for a telephone system.

According to the present invention, it is possible to easily expand a service by providing a service among group members having a large volume of traffic by building a server in a group unit, and by connecting a plurality of servers constructed in each group unit, It is possible to distribute the burden on the facility investment even if the number of users increases, so that the facility investment can be facilitated, thereby providing high quality call quality.

1 is an illustration of a call connection diagram according to the present invention.

The present invention is an Internet telephone system using a plurality of servers, and provides not only voice communication between subscribers but also video, text and data transmission / reception services.

The present invention can be configured as follows.

A central server that manages phone numbers and relay servers.

Each of the relay servers providing the Internet telephone service

Internet-enabled terminals

.

The central server stores the telephone number and the IP address of the relay server in which the corresponding telephone number is registered, and returns the IP address of the relay server in which the requested telephone number is registered upon request from the terminal or the relay server.

If one central server can not service all telephone numbers, it can have multiple central servers by country or region.

In this case, each relay server or terminal must have the IP address of each central server or be able to extract the IP address of the corresponding central server from the telephone number.

For example, assuming that the domain name of the service server according to the present invention is telno.net, the central server in South Korea can be defined as 2.82.telno.net.

When there is a connection request to the terminal registered in the relay server, the relay server establishes a connection and relays transmission / reception of voice, image, text, or data.

The relay server can be set up at each home, company, organization, and region, so that members can make free or low-cost calls among members, and can freely or inexpensively communicate with members using these relay servers using different relay servers.

That is, a device or a program serving as a relay server is installed in the home, and a general telephone number or a cell phone number of a family member is registered in the corresponding device, so that the same relay server is used between the family members regardless of the geographical position of the member You can make free calls, and you can also make free calls with members of other family members who have installed the relay server.

Alternatively, a relay server may be installed for each company or organization, and a general telephone number or a cellular phone number of a member of a company may be registered, so that even if the user is located at a branch office or a branch office, You can also make free or low-cost calls with the employees of other companies or organizations that have installed the relay server.

Alternatively, a relay server may be installed for each city and state, and a general telephone number or a mobile phone number of a local resident may be registered, so that the same local resident can freely or cheaply communicate using the same relay server regardless of the geographical location of the resident , You can also make free or low-cost calls to residents of other areas where you have installed the relay server.

Of course, it can also be linked to the relay server installed in each home, company, group, or region, for example, free or low-cost call to a person registered in the relay server installed in the home, can do.

However, most home networks use one Internet line and connect to the Internet through a router. Therefore, if you connect to a specific port of the router by using port forwarding function of the router, you must configure it to connect to the relay server inside the router.

In addition, if the IP address of the relay server is changed when a dynamic IP is used, such as an Internet line used in most households, the central server or the relay server recognizes the IP address and registers the changed IP address in the central server.

Of course, even if you use dynamic IP, you do not need to use the server name instead of the IP address and if you can find it using the DDNS server name.

A relay server installed in a home, a company, or an organization can connect a general telephone by adding a device supporting a general telephone to a relay server like a current Internet telephone gateway device, or use a relay server in conjunction with a key telephone or a private branch exchange , The relay server itself may play the role of a key phone or a private exchange.

For convenience of explanation, the relay server in which the outgoing telephone number is registered is called an origination relay server, and the relay server in which the received telephone number is registered is called a reception relay server.

A terminal is a terminal capable of connecting to the Internet.

Devices that can not connect to the Internet, such as a regular telephone, include devices that allow the device to connect to the Internet.

In the case of using a terminal having an original telephone function such as a smart phone or a general telephone, if the receiver is a user who uses the Internet telephone according to the present invention, the receiver connects to the Internet telephone, otherwise, .

A plurality of telephone numbers such as a mobile phone number, a home telephone number, and a business telephone number can be registered in one terminal.

In this case, since the relay server may be different for each telephone number, the terminal registers with each relay server for each telephone number.

When a plurality of telephone numbers are added to one terminal, it can be distinguished by changing the ringing tone for each telephone number or displaying the incoming telephone number on the screen.

In addition, the following functions can be added to the relay server or terminal when several people share the telephone number as follows.

If multiple smartphones share a single phone number, such as when registering a home phone number with each family member's smartphone, you can prioritize each phone number and connect to a higher priority terminal first, If you do not receive it, it will automatically skip to the next number, and you can return the call to another person during the call.

In some cases, several people share a telephone number without assigning a direct telephone number to individuals on a corporate telephone. In this case, the telephone number or the employee may be prioritized, or the same priority may be given to all persons, If anyone calls you, you can stop ringing.

If the terminal uses a private IP address and does not exist in the relay server internal network, the relay server can not connect to the terminal. Therefore, the terminal always maintains the connection state by connecting to its own relay server.

In addition, since the number of terminals managed by one relay server is limited in the distributed Internet telephone system according to the present invention, even if terminals subscribed to the relay server are concurrently connected, the relay server can sufficiently cover the terminals.

The following describes the process for setting up the present invention.

First, the relay server manager registers the relay server in the central server.

In the case where the relay server is fixed as in the case where the relay server exists on a regional basis, this process may be omitted and the central server manager may register each relay server with the central server. However, If the server exists or if the registration and termination of the relay server is free, if the relay server is flexible, this process is necessary for the central server to identify each relay server.

First, the relay server administrator can perform procedures such as membership registration to the central server.

At this time, you can authenticate yourself by various methods such as certificate, Ipin, mobile phone, document submission.

Step 1, the relay server manager registers the relay server in the central server.

In step 1-1, the relay server manager connects to the central server through the relay server and logs in.

In step 1-2, the relay server manager provides the relay server information such as the IP address of the relay server or the server name or automatically recognizes it from the central server.

Step 2, the central server stores the identification information of the relay server and the IP address or server name.

The identification information may be an ID input by the relay server manager, a unique ID issued by the central server, or unique information of the relay server device such as a MAC address.

Step 3, the relay server stores the identification information assigned to itself.

Of course, the relay server administrator may perform the above process through another computer and store the identification information in the relay server.

The central server then authenticates the relay server in such a manner that identification information is automatically transmitted to the central server when the relay server is operated, or the central server automatically recognizes the relay server.

If the information of the relay server is changed, the relay server manager performs authentication again, or the relay server transmits its information to the central server and is authenticated again.

Each of the following users registers their telephone number with the central server and the relay server according to the following procedure.

When a plurality of telephone numbers are registered in one terminal, they are registered for each telephone number.

First, if you know the relay server to connect to, you can do the following.

The user can perform procedures such as membership registration to the relay server in advance.

At this time, you can authenticate yourself by various methods such as certificate, Ipin, mobile phone, document submission.

In addition, the user installs the Internet phone app of the present invention on the terminal.

In step 1, the user accesses the relay server through the terminal and logs in.

Step 2, the user inputs the telephone number and requests registration to the relay server.

Register your cell phone number, home or business phone number.

When a telephone number is assigned to a smartphone and the assigned telephone number can be automatically recognized, the telephone number is automatically recognized first.

The user inputs the telephone number other than the telephone number to which the telephone number is not assigned, the terminal which can not automatically recognize the granted telephone number, and the telephone number to which the terminal is connected. In this case, have.

Alternatively, an e-mail address may be used in addition to the telephone number, or a telephone number to be used when a new telephone number is assigned in the Internet telephone system according to the present invention may be selected.

Step 3, the relay server registers the terminal identification information and the telephone number.

The identification information may be an ID entered by the user, a unique number automatically issued by the relay server, unique information such as the MAC address of the terminal, and the terminal may transmit the identification information to the relay server, The relay server can authenticate the terminal by various methods such as the server automatically recognizing the terminal.

Step 4, the relay server or the terminal transmits the identification information and the telephone number of the relay server to the central server.

At this time, the identification information of the terminal can be transmitted together so that the central server can recognize the terminal.

Step 5, the central server registers the transmitted relay server information and telephone number.

At this time, if the identification information of the terminal is transmitted, it can be stored.

Step 6, if successfully registered, the terminal stores its identification information, telephone number, and relay server information for the corresponding telephone number.

Of course, the user can input information to the terminal after performing the above process through another computer.

In the above, the procedure of registering the terminal with the relay server and registering the relay server with the central server has been described.

Also, the user can perform procedures such as membership registration to the relay server in advance.

In addition, the user installs the Internet phone app of the present invention on the terminal.

Step 1, the user accesses the central server through the terminal and logs in.

Step 2, the user enters the telephone number and requests registration to the central server.

In step 3, the central server automatically assigns the relay server to be accessed by the user or selects the relay server to the user, and registers the relay server identification information and the telephone number.

Step 4, the central server registers the terminal identification information and the telephone number.

Step 5, the central server or the terminal transmits the terminal identification information and the telephone number to the relay server, and the relay server registers the same.

Step 6, if successfully registered, the terminal stores its identification information, telephone number, and relay server information for the corresponding telephone number.

Also, the user can input information to the terminal after performing the above process through another computer.

When the information of the terminal is changed or when the relay server in which the telephone number is registered is changed, a new authentication procedure is performed by connecting to each relay server or the central server.

After that, the terminal connects to each relay server and maintains the connection state as follows.

When a plurality of telephone numbers are registered in one terminal, it is connected to each relay server by telephone number.

In the first step, the user terminal accesses the relay server in which the telephone number is registered

In the second step, when the relay server uses the dynamic IP, the IP address of the relay server can be changed, so that the terminal can access another relay server.

Accordingly, the relay server checks whether the received telephone number is a registered telephone number, and permits the connection if it is a registered telephone number, and returns an error if it is an unregistered telephone number.

Of course, when the relay server uses the server name instead of the IP address, it can be prevented that the relay server is connected to another relay server due to the IP address change.

In step 3, if the relay server returns an error indicating that it is not a registered telephone number, the terminal connects to the central server and transmits its telephone number.

In step 4, the central server retrieves and returns the relay server registered with the corresponding telephone number from the transmitted telephone number.

In step 5, the terminal updates its relay server information and proceeds to step 1 to access the relay server again.

In this process, the relay server or the central server can authenticate the terminal and return an error if the terminal is not authenticated.

Instead of accessing the relay server first, the user first accesses the central server, obtains the IP address of the relay server for the telephone number, and then connects to the relay server.

The process of making a call using the present invention will be described step by step with reference to the drawings.

Step 1, the user enters the recipient phone number and dials.

When a plurality of telephone numbers are registered in one terminal, the calling telephone number can be selected.

In step 2, if the receiving relay server information is stored in the calling terminal, the terminal proceeds to step 9 to access the receiving relay server. If not, the terminal transmits the receiver's telephone number to the calling relay server.

Step 3, the calling relay server checks the recipient phone number transmitted.

In step 3-1, it is checked whether the recipient's telephone number is an internal telephone number to which the subscriber is subscribed. If the telephone number is an internal telephone number, step 9 is performed to connect to the recipient.

In step 3-2, if the receiver's telephone number is not an internal telephone number but the received relay server information is stored in the relay server database, the stored received relay server information is returned.

The result may not be returned to the terminal but may be directly bypassed to the receiving relay server.

Step 3-3, if the recipient phone number is neither an internal phone number nor stored in the database, an error is returned.

It can request the receiving relay server information to the central server without returning the result to the terminal.

In step 4, the terminal operates as follows according to the result returned from the calling relay server.

If the receiving relay server information is returned, the process proceeds to step 7 to access the receiving relay server. If an error is returned, the receiving relay server accesses the central server and transmits the receiver's telephone number.

In step 5, the central server retrieves the relay server information in which the corresponding telephone number is registered, from the recipient telephone number of the recipient, and returns.

In step 5-1, the central server retrieves the recipient's telephone number transmitted, and if the recipient's telephone number is not retrieved, the receiver returns an error because it is a telephone number not registered in the Internet telephone service according to the present invention.

In step 5-2, the central server returns the information of the receiving relay server.

Of course, at this time, the result can be bypassed to the receiving relay server without returning the result to the terminal.

In step 6, if the receiving relay server information is returned, the terminal proceeds to step 7 and connects to the receiving relay server. If an error is returned, the terminal proceeds to step 11.

Step 7, the receiving relay server checks the recipient's telephone number.

When the relay server uses the dynamic IP, the information stored in the calling terminal or the calling relay server may be different from the actual receiving relay server, and the information may be different even when the relay server is changed due to withdrawal or migration of the subscriber.

In step 7-1, the receiving relay server checks whether it is a registered phone number, and returns an error if it is not registered.

In step 7-2, the receiving relay server checks whether the corresponding receiver is connected when it is a registered phone number, and returns an error to the terminal if it is not connected.

In step 7-3, when it is registered with itself and the connection is established, the receiving relay server proceeds to step 9 and connects.

Step 8, the calling terminal operates as follows according to the return result.

If the information is stored in the terminal or the calling relay server but the telephone number is not registered in the receiving relay server, the information of the receiving relay server may be different. Therefore, the terminal proceeds to step 6 and requests the receiving server information do.

In the case of connecting using the information received from the central server, there is no way to connect to the central server.

If the recipient's telephone number is not currently connected, proceed to step 11.

Step 9, the receiving relay server establishes a connection to the receiver, and relays transmission and reception of voice, video, or data after connection.

Step 10, if the connection is successful, end the call.

The terminal or the calling relay server can store the receiving relay server information in its own database.

In step 11, the terminal guides the user of the error contents to the screen or voice.

When the terminal is a terminal having a telephone function such as a smart phone or a general telephone, the terminal can make a connection using the call function of the terminal itself.

In order to reduce the load on the central server, it is attempted to access the receiving relay server using the information stored in the terminal or the calling relay server. However, all or part of the steps 2 to 4 may be omitted, It is also possible to obtain the relay server information in which the number is registered and then connect to the receiving relay server.

The relay server authenticates the terminal in the step of accessing each terminal registered to itself, and the central server authenticates the registered relay server. However, between the sending relay server and the receiving relay server, between the calling terminal and the central server or the receiving relay server, There may be no.

Therefore, in order to authenticate the calling terminal, the connection relay server can connect to the central server through the transmission relay server, or can connect to the reception relay server through the originating relay server or the originating relay server and the central server. In the following method, Authenticate the terminal.

First, the calling relay server transmits information for identifying the calling terminal, such as the IP address of the calling terminal, to the receiving relay server, and the receiving relay server checks and authenticates the IP address of the calling terminal.

Second, when the calling terminal requests the call, the calling relay server generates the unique number and transmits it to the receiving relay server and the calling terminal. When the calling terminal connects to the receiving relay server and transmits the received unique number, the receiving relay server checks it Authentication.

In this case, each relay server or terminal must have the relay server information of each received telephone number or obtain the IP address of the receiving relay server from the received telephone number do.

For example, if the domain name of the service using the present invention is telno.net, the telephone number may be 82.telno.net or 2.82.telno.net or 2281.2 You can also specify .82.telno.net.

In this case, since there is no central server, the terminal registers the telephone number only in the relay server, and the terminal directly connects to the receiving relay server or connects to the receiving relay server through the calling relay server for terminal authentication.

The central server and the relay server may be used in appropriate combination.

For example, when a relay server is provided for each region, a telephone number classified by region such as a regular telephone is directly connected to the corresponding relay server, and a telephone number having no area classification such as a cell phone or 070 telephone is received through a central server. Information can be obtained.

Although the above description has been made on the case where the caller terminal transmits and receives voice, video, text, and data through the receiving relay server after the caller terminal is connected to the receiver, the voice and video, text, and data are transmitted / received through the calling relay server and the receiving relay server You may.

The foregoing is merely an example of the present invention, and various modifications and modifications are possible.
