Gatekeeper having function of temporary ID registration and communication transit tandem}

The present invention relates to a communication device, and in particular, registers a call received to a user's own IP terminal from the outside by using the Internet roaming service by temporarily registering an IP terminal installed in an arbitrary area with a gatekeeper as a user ID to which a call is forwarded. It relates to a gatekeeper having a temporary ID registration and communication relay function to control the return to the IP terminal of the.

As communication technology develops, telephone call technology using the Internet is widely spreading. There are two ways to make a phone call using internet phone technology at home.

First, there is a method of using an Internet phone using a computer.

When using an Internet phone by using a computer, an IP address is assigned by connecting to an Internet Service Provider (ISP) using Point to Point Protocol (PPP), a modem and software for Internet access. By completing preparation for TCP / IP to run, it is possible to connect to the other host for the voice call. Subsequently, when the PC user attempts to connect to the called party by running the Internet phone program and the other party answers, the voice call is connected and the telephone call can be made.

Second, there is a method using an internet phone.

If you are using an Internet phone, instead of running your computer, connect your Internet line to your Internet phone, enter your subscriber ID and set up your gatekeeper information once, and you will be ready to use it like a regular phone. Free calls can be made to Internet phones, and at the same time, Internet phone service companies can make inexpensive calls from Internet phones to regular phones.

In such an internet phone call system, when both IP phones and IP phones are used, domestic and international calls can be called cheaply. By the way, the current Internet phone service has a problem that is inconvenient to use, which can not only receive a call received by the user ID with their own dedicated Internet phone, but also can not be freely received by any IP terminal in the third place, and also arbitrary There was an inconvenience in use that the IP terminal can not be registered and used temporarily as a dedicated IP terminal of each individual.

The technical problem to be solved by the present invention is to temporarily register an arbitrary IP terminal as a user ID to the gatekeeper in order to solve the above-mentioned problem, so that a call received from the own telephone can be returned to the IP terminal installed at a third place. The present invention provides a gatekeeper having a temporary ID registration and communication relay function for controlling.

The gatekeeper 110 has a function of controlling a network, performs an authentication operation for determining whether to permit an incoming call from the outside, and executes a control for a bandwidth change request. In addition, the conversion between the telephone number and the IP address of the Internet phone is performed using the IP conversion table already registered in the database. For customers using a static IP, the IP address that matches the Internet phone number in the translation table is fixed.However, if the customer uses a dynamic IP, such as ADSL and cable modem, the customer can use the regular IP address between the customer's Internet phone and the gatekeeper. Through the exchange of personal information, it always checks and stores the changed IP address that matches the subscriber ID (the phone number of the Internet phone, H.323ID and E.164ID), and checks the IP address that matches the incoming Internet phone number. Support phone calls as possible.

The gatekeeper 110 registers the ID information of the IP terminal to be forwarded to the IP conversion table by matching the user ID information transmitted by the temporary ID registration program from the IP terminal 130.

Therefore, in the present invention, when the gatekeeper 110 receives the temporary ID registration request from the IP terminal 130, the gatekeeper 110 executes a process of registering the IP terminal requesting the temporary ID registration as a user ID in the IP conversion table.

When connected to the public public telephone network 2000 or the wireless switching network 3000, the connection is based on the telephone number, and the connection to the Internet network 1000, which is a packet network, is connected to each other based on the IP address. Therefore, the gateway 120 stores the IP address and the telephone number at the same time.

Next, the operation of the gatekeeper applied to the present invention will be described with reference to FIG. 2.

As shown in FIG. 2, a gatekeeper having a temporary ID registration function and a communication relay function according to the present invention includes a database 210, a control module 220, a communication module 230, and an IP router module 240. .

In detail, the database 210 is composed of a user information database 210-1 and an IP translation table database 210-2.

The user information database 210-1 stores the names, addresses, e-mail addresses, E.164IDs, and alias names of the users registered with the gatekeeper for incoming call authentication. An IP address, alias information, an E.164ID, an e-mail address, a call forwarding IP address, a call forwarding option information, and a status information field are shown in 210-2 for IP address translation of the E.164ID. The IP conversion table composed of the data is stored.

In detail, the configuration items of the IP conversion table are as follows.

In the IP address field, IP address information of the user's own IP terminal registered to the gatekeeper is stored.In the Alias name field, the alias name of the registered user is stored.In the E.164ID field, the IP address of the user's own IP terminal is stored. Internet phone number information is saved, and the registered user's e-mail address information is stored in the e-mail address field, and the IP address information to which the IP terminal registered with the user ID is temporarily stored is stored in the forwarding IP address item. It is. Therefore, when temporarily registering an IP terminal other than the user's own IP terminal already registered with the user ID, the IP address information of the IP terminal temporarily registered as the user ID is stored in the destination IP address field matching the user ID. do.

The call forwarding option information field stores user option information such as time information for receiving call forwarding service. This is for temporarily setting an IP terminal registered as a user ID to receive a call received by the user's own IP terminal only in a specific time zone.

Information indicating the connection status of the registered IP terminal is stored in the status information field. For example, the status information field is set to "0" when waiting, "1" when on a call, or "2" when offline. This status information field displays the connection status of the temporarily registered IP terminal when another IP terminal is temporarily registered with the user ID.

In detail, the control module 220 includes an authentication control module 220-1, an ID registration control module 220-2, and an IP conversion control module 220-3.

The authentication control module 220-1 executes a process of authenticating whether the incoming call is permitted using the user information registered in the user information database 210-1 when the IP terminal is connected.

The ID registration control module 220-2 registers the user's own ID registration process and other IP terminals temporarily as user IDs, and temporarily registers IP addresses of IP terminals temporarily registered as user IDs in the forwarding IP address item of the IP conversion table. Run the process to save the address.

The IP conversion control module 220-3 executes a process of converting the Internet telephone number (E.164ID) of the called party's IP terminal to be called into an IP address using the IP conversion table database 210-2. If the call forward IP address by temporary ID registration is registered in the IP conversion table, the user ID is converted to the call forward IP address.

The communication module 230 includes a wired communication module 230-1 and a wireless communication module 230-2, and the wired communication module 230-1 is a wired communication method between a gatekeeper and IP terminals. The wireless communication module 230-2 executes communication and performs data communication by a wireless communication method between the gatekeeper and the IP terminals.

The IP router module 240 executes a process for network address translation of a terminal in a local network and for designating a communication path between a source and a destination IP address. The IP router module 240 uses an address that is not registered as an IP address of terminals in the local network by using a network address translation (NAT) function within the local network, and uses an address registered as an IP address outside the local network. It identifies the network and the terminals in the local network share the unique IP address of the IP router assigned to the local network.

Next, the operation of the IP terminal will be described in detail with reference to FIG. 4.

As shown in FIG. 4, an IP terminal applied to the present invention includes a control unit 410, a key input unit 420, a display unit 430, a communication module 440, a digital signal processor (DSP) 450, and a memory ( 460, a codec module 470, and a smart card reader 480.

The communication module 440 is composed of hardware and software for executing data communication by the gatekeeper and the wired communication method and the wireless communication method. The smart card reader 480 may be deleted according to design specifications.

The memory 460 includes ID information (E.164ID, H.323ID, e-mail address, etc.) for registering an IP terminal, and a program and data for executing a process of temporarily registering the IP terminal with another user ID in the gatekeeper. Are stored. Of course, the programs needed to access the Internet are also stored.

As a method of temporarily registering the IP terminal with any other user ID, there are a method of registering by using a smart card and a method of manually inputting by key input of the key input unit 420.

The controller 410 operates a program stored in the memory 460 to receive user ID stored in the smart card through the smart card reader 480, together with user ID temporary registration request information and user ID information (E. 164ID, H.323ID, e-mail address, etc.) and the ID information registered in the IP terminal to the gatekeeper.

The codec module 470 encodes the analog voice signal input from the microphone into digital data after the communication path is opened, and is connected to the communication line 440 via the Internet 1000 via the gatekeeper 110 by the communication module 440. It is output to the IP terminal or gateway 120 connected to the, and the digital data received from the communication module 440 is decoded and then converted into an analog signal and output to the speaker.

The digital signal processor (DSP) 450 performs a graphic process on the user ID information received by the temporary ID registration process and information necessary for Internet phone call and setting, and outputs them to the display means 430 such as a liquid crystal display.

Next, a process of temporarily registering another IP terminal in the gatekeeper as a user ID will be described with reference to FIG. 5.

First, when the temporary ID registration request information is received from the IP terminal to the communication module 230 (S51), the gatekeeper operates the authentication control module 220-1 to request the ID of the IP terminal requesting the temporary ID registration. It is checked whether it is registered in the information database 210, and if the authentication is successful, request transmission of user ID information to be temporarily registered and ID information of the IP terminal to be forwarded to the corresponding IP terminal (S52). Here, the temporary ID registration request information can be designed by a combination of specific numbers.

Then, user ID information (E.164ID, H.323ID, e-mail address, etc.) input from the smart card reader 480 or the key input unit 420 and ID information of the IP terminal read from the memory 460 (E). .164ID, H.323ID, e-mail address, etc.) are also transmitted to the gatekeeper (S53).

Accordingly, the gatekeeper ID registration control module 220-2 corresponds to the ID information (E.164ID, H.323ID, e-mail address, etc.) of the IP terminal temporarily registered as the user ID from the IP conversion table. Read the IP address and store the IP address in the forwarding IP address field that matches the user ID information (E.164ID, H.323ID, e-mail address, etc.) in the IP conversion table to temporarily store the IP terminal. Register by user ID.

After the gatekeeper temporarily registers another IP terminal in the IP conversion table as the user ID, the gatekeeper transmits response information indicating that the temporary user ID registration is completed to the corresponding IP terminal and terminates the process (S54).

The process of canceling temporary registration of an IP terminal installed in a certain place with a specific user ID is similar to the registration process, and differs from the registration process in that it transmits ID cancellation information instead of only ID registration request information.

Next, a process of relaying communication between IP terminals in the gatekeeper will be described with reference to FIG. 6.

The authentication control module 220-1 determines whether call request information is received through the communication module 230 (S61).

When the call request information is received, the authentication control module 220-1 searches the user information database 210-1 to check whether the user ID registered as the received IP terminal corresponds to the ID registered in the gatekeeper. The authentication process is executed (S62). If the authentication result is the ID registered in the user information database 210-2 (S63), the IP conversion table is searched to determine whether the status information of the IP terminal matching the called party ID information is set to the standby state (S64). ). However, if authentication fails, response information informing of a connection failure is transmitted (S69).

If the status information is set to the standby state, it is checked whether or not the call forwarding IP address by temporary ID registration is set (S65). However, if the status information is set to the busy state or the offline state, the response information indicating the connection failure is transmitted (S69).

If the forwarding IP address is set to match the called party ID (E.164ID, H.323ID, e-mail address, etc.), the call forwarding IP address information is read (S66), and the read forwarding IP address is read. Attempt to connect by call (S68).

However, when the call forwarding IP address matching the called party ID (E.164ID, H.323ID, e-mail address, etc.) is not set, the IP address information of the initially registered IP terminal is read (S67), A connection is attempted to a call to the read IP address of the user's IP terminal (S68).

Accordingly, if any IP terminal installed in the third place is temporarily registered with the gatekeeper with the user ID, the telephone call received by the own IP terminal can be returned to any IP terminal installed in the third place. .

Specific embodiments shown in the accompanying drawings are to be understood only as an example of the present invention, and do not limit the scope of the present invention, and various technical scopes described in the present invention in the technical field to which the present invention belongs. As other changes may occur, it is obvious that the present invention is not limited to the specific configurations and arrangements shown or described.

As described above, according to the present invention, any IP terminal can be temporarily registered with the gatekeeper regardless of the place so that the user ID can be temporarily registered, thereby temporarily registering a call to the user's own phone at a third place. It can be returned to the used IP terminal, and a convenient effect is generated, and an effect of temporarily using an IP terminal that is not owned by the user can be used like a user's own IP terminal by a temporary ID registration process.
