Description

Address registration and connecting maintenance method and circuit for interconnection between systems based on dynamic IP address}

The present invention relates to a registration process for interconnection between systems connected to the Internet network based on a dynamic IP address and a method for maintaining the connection, and more particularly, a phone number of a counterpart to register using an existing PSTN network. To register an address and maintain the connection for the interconnection between dynamic IP address-based systems that make an ARS phone call and make a network connection through a direct registration / auto registration process depending on whether the other party accepts the registration And a circuit portion.

Every network device connected to the Internet has its own unique TCP / IP address. Using this IP address, it is possible to access the network device from the outside network and use the Internet service.

IP addresses needed to access these Internet networks are divided into static and dynamic IP addresses. The fixed IP address has the advantage of being able to connect using the fixed IP address anytime and anywhere because the IP address assigned by the ISP does not change, but there is a disadvantage that a high cost is required to use the fixed IP address.

Dynamic IP addresses can vary from one IP address assigned by your ISP. Therefore, since the variable IP address is not known to the external remote site, there is a disadvantage in that it cannot be accessed directly.

In order to solve this problem, the most commonly used method includes a specific relay server that has a database that can store unique identification information such as a unique ID and an assigned IP address of a system connected to the Internet with a dynamic IP address. If there is a request for access from an external remote location, the ID of the system is searched and connected to the currently assigned dynamic IP address.

The embedded system 100 includes an embedded terminal 110 that provides specialized services, and each embedded terminal 110 receives a dynamic IP address from the DHCP server 200 through an internet network and accesses the Internet. Provides a variety of services to the user terminal (300).

The DHCP server 200 allocates dynamic IP addresses so that the embedded terminal 110 of the embedded system 100 can access the Internet network and provide a service.

The management server 400 manages IP address information that the DHCP 200 gives to the embedded terminal 110. The management server 400 is notified of an event when the embedded terminal 110 is given a new IP address from the DHCP server 200, such as when the power of the embedded terminal 110 or the Internet is disconnected and connected again. Store and manage IP addresses.

Manage it. That is, when the subscriber module 420 receives the request of the user terminal 300 to service the embedded terminal 110, the subscriber module 420 determines whether the corresponding user is a service subscriber, and determines the IP address of the embedded terminal 110. Provided by 300. The embedded system management module 430 enables the management of the embedded system 100 at a remote location, and performs event processing due to the addition and removal of the embedded terminal 110. The DB 440 includes a terminal mapping table that stores subscriber information and IP address information provided to the embedded terminal 110.

In such a conventional network structure, a relay server for connecting between terminals having a dynamic IP is required to exist separately, and an expensive database construction cost for processing a plurality of users is required to install a relay server. This is an economically and practically impossible way to use Internet services by interconnecting a small number of users.

In order to fully understand the present invention, the advantages of the operability of the present invention, and the objects achieved by the practice of the present invention, reference should be made to the accompanying drawings, which illustrate preferred embodiments of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference numerals in the drawings denote like elements.

2 is a diagram illustrating an address registration and a method for maintaining a connection for interconnection between dynamic IP address-based systems according to an exemplary embodiment of the present invention.

Referring to FIG. 2, the present invention is characterized by using an existing PSTN network, and an initial address registration process and a connection maintaining method using a PSTN network between systems will be described in detail as follows.

First, the system A connects a call to the ARS from the system B to the counterpart system that wants to register first. When the call is connected, the other party, System B, can decide whether to register the address. For example, the system B, according to the ARS voice prompt, registers' 1. Reject ".

Types of registration methods in the present invention are exemplified by " direct registration method " and " automatic registration method ", and " automatic registration method "

First, when a registration request call is received by the ARS, the direct registration method is performed by selecting "1. Registration" in the system B, and then selecting a button corresponding to direct registration among "direct registration / automatic registration" after the selection. After that, if the IP address to which the system B is connected is "221.254.177.67", the user inputs an IP address such as '221 * 254 * 177 * 67 #' from the user terminal using the DTMF generator. In the transmission step of transmitting the received IP address to the system A (S100), the system A that makes a registration request call interprets the DTMF signal received from the system B as a DTMF receiver and stores the IP information of the system B in the system A. Receiving step (S110), which is stored with the unique identification ID (line number) of the system B, which is stored in the system A is connected through the Internet network using the IP information of the system B registered in the system A and the current unique identification ID of the system A ( Retransmitting system information data having data fields such as a trunk line number) and IP information to system B (S120), and system information retransmitted from system A, which has requested a registration in system B; It comprises a material receiving step (S130) for registering the data.

3 is a diagram illustrating an address registration and a method for maintaining a connection for interconnection between dynamic IP address based systems according to another exemplary embodiment of the present invention.

Referring to FIG. 3, in the automatic registration method, when a registration request call is received from the system A to the ARS, the system B selects "1. registration" and then automatically registers a menu such as "direct registration / auto registration". This is done by selecting the corresponding button.

If you disconnect the call after selecting "Auto Registration" in System B, the PSTN network will be temporarily hooked off. Thereafter, the automatic registration process is performed by selecting the automatic registration button connected to the Internet line in the system B.

The automatic registration process will be described in more detail. In the system B, which is connected to the Internet, the step of retrieving the current IP information allocated from the ISP using the IP information check unit and DTMF transmission of the current IP information from the DTMF transmitter In the automatic transmission step (S200) of transmitting a DTMF signal to the system A using a generator, the system A that makes a registration request call interprets the DTMF signal received from the system B as a DTMF receiver and interprets the IP information of the system B. Receiving step (S210) stored with the unique identification ID (line number) of the system B stored in the system A, using the IP information of the system B registered in the system A to access through the Internet network and the current system A Retransmitting system information data having a data field such as unique identification ID (line number) and IP information to system B (S220), at system B, and so on. And a re-receiving step (S230) of registering the system information data retransmitted from the system A which made the lock request.

As a method of registering the IP address of the system to the system without using the above-described PSTN network, if the ID and IP address of the counterpart system are known, the ID and IP address of the counterpart to be registered on the system can be registered using the GUI registration window. Direct registration can be used.

In addition, you can register by entering the other party's ID and IP address by using the 'Register' program on the PC connected to the system and internal IP.

After the initial registration process described above, IP information is registered internally between System A and System B, and Internet services can be used without a relay server.

4 is a diagram illustrating an address registration and a method for maintaining a connection for interconnection between dynamic IP address based systems according to another preferred embodiment of the present invention.

4, another feature of the present invention is that even if the IP information is changed in either system, the IP information check unit checks the changed IP information and does not update the corresponding ID and IP information in the relay server. For example, a system in which IP information has been changed can be maintained by accessing the system information data such as a unique identification ID and a changed IP address to each IP address in a group stored in the system using the Internet network.

For example, assuming that the IP address of the system A has been changed, the system A transmits its unique identification ID and the changed IP address to the system B using the IP address of the system B stored therein (S300). In step S310, the system B receives system information data received from the system A whose IP address is changed in the system B, and compares the system information data received from the system A in the system B with the previously stored database information. The connection is maintained according to the IP information changing step (S320) of updating. This is called a data synchronization process.

When the IP address is changed in a series of steps described above, it is done in a batch so that the mutually registered systems are always connected to the Internet network regardless of whether the IP address assigned by the ISP is a fixed IP address or a dynamic IP address. As a result, anytime, anywhere Internet services such as data transfer, file transfer and video transfer can be used.

FIG. 5 is a diagram illustrating an address registration and a connection maintaining method for interconnection between dynamic IP address based systems according to another preferred embodiment of the present invention.

Referring to FIG. 5, if there is no response from the other system during the process of synchronizing the IP information data between specific systems, or if the synchronization process fails, the re-registration process is automatically performed in the disconnected system.

The automatic re-registration process, assuming that the connection is disconnected from the system A, transmitting a message with reference to the IP address of the group previously registered in the booting process (S400), the Internet network by changing the IP address, etc. If it is impossible to connect through the ARS call connection using the PSTN network to the other party B with no response (S410), when the call is connected with the system B, the system A transmits a specific DTMF signal (for example, 0) In step S420, it refers to a connection maintenance process performed through the step (S430) of retransmitting the IP address information changed in the system B receiving the specific DTMF signal to the system A using the DTMF signal.

The process of maintaining these interconnections is always carried out between systems so that if the power is turned off or if the interconnect is lost in an unexpected situation, it can be reconnected to maintain the connection.
