Description

A system and method for transmitting an electronic data using centralized routing information}

The present invention relates to an electronic data transmission system using a central routing information and an electronic data transmission method therefor. More particularly, the electronic data transmission system uses electronic routing using the routing information after requesting and providing routing information during electronic data transmission. An electronic data transmission system using central routing information for transmitting data, and an electronic data transmission method therefor.

FIG. 1 shows a conventional overall network configuration for transmitting an electronic fax document through an Internet network, wherein a user uses a facsimile to fax image data or a personal computer (PC). electronic documents relating to, when transmitted through the public switched telephone network (PSTN) (100 ₁₎ connected connection with the fax number of the recipient to receive it as a local fax server _{(200: 1),} has received this local fax server (200 ₁ ), If the fax content is received in the form of an electronic document, it is converted into fax data, and in the case of fax image data, the fax information corresponding to the recipient's fax number is converted using routing information that is received and converted without management. The local fax server (200 _X ) is determined for the local fax server that is closest to the region (country, state or province) and has a low usage rate.

As described above, when the other side's local fax server 200 _X is determined, the received fax document or converted fax document is transmitted to the determined local fax server 200 _X through the Internet network 300 together with the recipient's fax number. Local fax server (200 _X ) receiving this through the Internet network (300) is to form an international call, long distance or local call through the public telephone network (100n), the fax received with the fax document The transmission of the fax data is completed by transmitting to the destination corresponding to the number.

However, in order to transmit the fax data between the regional fax servers as described above, the contract between the regional fax servers had to be made first. In other words, when a new fax server was newly installed in a specific region, the regional fax server is a different regional fax server. It was possible to send fax data to the contracted local fax server only when the contract was signed with the contractor and also to receive fax data from the contracted local fax server.

In addition, each local fax server has information such as the location (country, state or province), usage fee, and address (e-mail address) of the other regional fax server in order to send the fax document at the lowest rate. All routing information included should be stored and managed.

However, if a new fax server is installed in a specific area, all local fax servers contracted with the installed fax server need to generate the installation location, fee, and address of the newly installed fax server as routing information, as well as other existing fax servers. Routing information for fax servers should also be updated and stored.

For example, if a new fax server is installed in the area C of FIG. 1, the routing for sending a fax to the area C on the routing information of the area A fax server 200 ₁ is addressed to the address of the area B or D fax server. Therefore, the routing information for the fax server in the region C should be changed as well as the routing information for the fax server in the existing B or D region. This is true even if the fax server installed in a specific region is removed. Therefore, all the local fax servers contracted with the removed local fax server are removed from the existing routing information and the routing information about the non-existing fax server is deleted. In addition, the routing information for the region must be updated, and in addition, when changing the policy of a specific fax server, the existing routing information must be updated and reflected, which is very cumbersome and requires a lot of time. As such, routing information must be stored and managed separately, resulting in unnecessary waste of resources.

In addition, since each local fax server stores and manages routing information individually, there is a problem that it is difficult to calculate the statistical data for the entire network fax transmission and reception.

Therefore, the present invention was created to solve the above problems, and concentrates the routing information for each local server, obtains the optimal routing information from the concentrated information at the time of electronic data transmission between the local server and using the electronic data It is an object of the present invention to provide a transmission system and a transmission method.

It is characterized by including the fourth step to do.

Hereinafter, an embodiment of an electronic data transmission system using a central routing information according to the present invention and an electronic data transmission method thereof will be described in detail with reference to the accompanying drawings.

FIG. 2 is a diagram illustrating the entire network configuration when the electronic data transmission system using the central routing information according to the present invention transmits the fax data. The network configuration of FIG. 1 is the same as that of FIG. It is configured to further include a central server (central fax server) 400 to store and manage the routing information for) alone, and to provide optimal routing information at the request of each local fax server.

3 schematically shows an internal configuration of a central fax server 400 for storing and managing routing information, the network connection unit 42 being connected to a signal network to the Internet; A hard disk 43 in which routing information for transmitting a fax document between a program and each local fax server 200 _X is stored; The Internet access protocols perform program (41a) and the local fax server (200 _X) between the data transmission protocol fax application that performs data configuration and decrypted according to (41b) and management for fax transmission and reception statistics and routing information management A central processing unit 41 which drives and executes the program 41c from the hard disk 43; A data input / output unit 45 for inputting data processing and outputting processing data; And a memory 44 in which the program is stored and managed.

4A and 4B illustrate a flow of a preferred embodiment of the electronic data transmission method using the central routing information according to the present invention, which is implemented from the transmission system of FIG. 2. Hereinafter, the configuration of FIGS. 2 and 3 will be described. Reference will now be made in detail to the fax data transmission method of FIGS. 4A and 4B according to the present invention.

First, in order to implement the electronic data transmission method using the central routing information according to the present invention, the central processing unit 41 of the central fax server 400 is three programs (stored in the hard disk 43) The Internet connection protocol execution program 41a, the fax application program 41b, and the management program 41c are read out and executed on the memory 44.

Thus, while in operation, contracted from a number of local fax server (200 _X) concluded the installation of local fax server (200 _X) location, network status, capacity of local fax server (200 _X) (whether overload ), Usage fee, e-mail address, and the like, the management program 41c executed by the central processing unit 41 is automatically operated by the operator through the data input / output unit 45 or automatically. Routing information is initially generated.

Thereafter, when the local fax server is newly installed or the local fax server is removed in a specific region, or when the central fax server 400 receives the information in writing or online according to a change in the usage fee system, The management program 41c updates the routing information on the hard disk 43.

That is, in the case where the routing information is configured by region division as shown in FIG. 5 (a), when a new local fax server 2003 having the lowest fee is added to the hatched C 'area, the routing information of the existing servers is determined. Update the routing information of the A area fax server, the B area fax server, and the D area fax server for the A ', B', and D 'areas, and update the new routing information for the A', B ', and D' areas. The server 2003 is constructed to configure routing information as shown in FIG. 5 (b). Conversely, if the fax server in region C is removed, the routing information as shown in FIG. As shown in the dotted line in a), the C region is divided to form routing information.

As such, the central fax server 400 for storing, managing and providing routing information is provided, and a contract is established between each regional fax server (200 _X ) and the central fax server (400). 200 _X ) periodically provide its network status information, such as accessible root and load, to the central fax server 400, the electronic document of the fax content requested from the user is the recipient fax. number and together, specified fax transmission request (S10) close to the user the local fax server (e. g., a local fax server (200 _1)), when transmission to, one receives the local fax server (200 ₁₎ By extracting the area code from the received fax number (S11) and transmitting it to the central fax server 400, routing information required for fax transmission to the destination is requested (S12).

The Internet access protocol execution program 41a executed in the central fax server 400 interprets the packet data received through the network connection unit 42 according to a protocol, and transmits the data transmitted by the local fax server 2001. Extract the bay and send it to the fax application (41b), the fax application (41b) grasps the area code of the destination from the received packet, that is, the national telephone number or the local telephone number (DDD number), Searching from the hard disk 43 to determine the other local fax server to which the fax document transmitted to the local fax server 2001 is sent (S13), the other local fax server of the fax application 41b. At the time of determination, it is determined from the routing information stored in the hard disk 43 by checking the local fax server closest to the requested destination and having the lowest cost. . That is, if the fax application 41b confirms the destination to Washington, USA from the received area code, if a local fax server located in Washington exists at the time of the local fax server's decision, the Washington fax server is used. The network server of the local fax server having the lowest fee is determined from the storage contents of the hard disk 43. As a result, the current fax server in the Washington area is determined. If there is a risk that data transmission may be disrupted due to poor network condition, or if it is determined that data cannot be transmitted, the fax application 41b requests the routing information through the Internet access protocol execution program 41a. The fax server 2001 requests the transmission standby state.

Accordingly, the local fax server 200 ₁ internally stores the requested fax document and maintains the standby state. When the standby state exceeds the predetermined time limit, the local fax server ( In 200 ₁ ), the central fax server 400 re-requests to transmit routing information of a next rank.

In the above, the central fax server 400 may provide the routing information of the next order unconditionally, without waiting for the local fax server. Thus, the central fax server 400 does not immediately provide the next-order routing information. To request a waiting status, fax document transmission by next-order routing information usually requires a little more charge than fax document transmission by optimal routing information. This is because it is desirable to be able to select to provide next-order routing information.

Accordingly, the fax application 41b in the central fax server 400 next determines and confirms the other regional fax server capable of transmitting the fax document to the destination. As described above, based on the routing information stored in the hard disk 43, it is determined that the local fax server is close to the destination but cheap. In other words, assuming that a fax server is installed in Washington, New York, and Los Angeles, USA, the Washington fax server, which is determined in the above manner, cannot confirm that the fax document can be sent to the destination, and then still send the fax document. If it is determined that the reliability cannot be secured by the network status information, the next-generation fax server is located close to Washington, so that the fax server is determined as a cheap New York fax server.

In addition, when determining the local fax server, the number of outbound / inbound fax documents of the local fax server is considered, and if the determined area fax server is larger than the number of outbound fax documents. If the number of inbounds is greater, there may be a risk incurred due to one-sided remittances for payment between local fax servers. Therefore, in consideration of this point, it is determined that the local fax server is closer to the local fax server determined above, but more outbound or more balanced than the inbound number of the fax document.

In consideration of various factors as described above, when the local fax server is finally determined, the fax application 41b checks the determined e-mail address of the determined local fax server from the hard disk 43, and the confirmed electronic The routing information including the postal address is transmitted to the corresponding local fax server 200 ₁ that requested it (S14).

Accordingly, the local fax server 200 ₁ receiving the routing information sends the requested fax document and the fax number of its destination to the local fax server corresponding to the received e-mail address. Through the transmission in the form of a packet through (S15), the receiving local area fax server receives the received fax image data through the public telephone network (100 _n ) by opening a call of a local, long distance or international call The destination is sent to the destination corresponding to the fax number (S16).

As such, when the transmission of the fax data to the corresponding destination is completed (S20), the local fax server transmitting the fax document to the destination through the telephone network is the central fax server 400 and the other local fax server 200 that has sent the fax document. ₁ ) to notify the completion of the transmission of the fax data (S21), it is possible to check whether the transmission to the destination of the fax document from the local fax server (200 ₁ ) and the central fax server 400 that sent the fax document.

In addition, the management program (41c) of the central fax server 400 is not only routing information on the hard disk 43, but also the usage history of each local fax server (200 _X ), that is, the number of times and the usage fee generated accordingly And the like, and if a notification is received from the local fax server as described above, the management program 41c updates and stores the usage history stored in the hard disk 43. read out to be (S22), from a specific area fax server (200 _X) when so requested by the usage history of the stored from the use history of the hard disk 43 of this, a specific area fax server (200 _X) requested Will be provided.

The above embodiment can be applied to a local server which relays voice mail or Internet phone instead of a fax server for transmitting fax data. The voice mail from the user, that is, an electronic document of voice data, is the telephone number of the destination. When the request is sent to the local mail server, it receives the routing information from the central mail server and transmits the voice mail to the other local mail server specified by the grouting information. After establishing a local, long distance or international call to the destination telephone number through the voice mail is received.

In addition, a method of providing routing information in the center may be applied to an Internet phone, which will be described in detail below.

First, the user first enters a phone number of a destination to be called through an internet phone or a computer (PC) equipped with Internet phone-related software.

Accordingly, when the phone number of the input destination is transmitted to a specific local phone server close to the user, the local phone server receiving the extracted phone code extracts the area code from the received phone number and transmits the area code to the central phone server. As described above, the central phone server provides an e-mail address as routing information of the destination local phone server having the lowest cost with the destination.

The local phone server provided with the e-mail address transmits a packet call setup-related message for transmitting and receiving voice data through the Internet, including the phone number of the destination, to the other local phone server of the provided e-mail address. Accordingly, the local area phone server on the other side opens a local, long distance or international call to a destination corresponding to the received phone number through the public telephone network of the area.

When the call establishment is completed, the two local phone servers transmit voice data input through the user's Internet phone in the form of packet data through the Internet network, and the packet data is converted into voice by the phone server and then the telephone network. Is passed through.

The electronic data transmission system using the central routing information and the electronic data transmission method therein according to the present invention constituted as described above are provided by installing a central server that stores and manages the routing information alone and provides it to each local server. In addition, each regional server collects and stores routing information for electronic data transmission between regional servers, and removes the hassle of updating routing information in all regional servers every time a specific regional server is installed or removed. This is a very practical invention that allows users to use the cheapest rate at the present time with the latest routing information. Also, since the central server stores and manages the routing information alone, it is easy to calculate the statistics of the entire network.
