Service method for Internet telephone number of Voice Over Internet Protocol Endpoints and resolution method of IP address in gatekeeper}

The present invention relates to a Voice Over Internet Protocol Endpoints (VOIP) telephone number service method and an address conversion method, and that a web phone telephone number user independently provided by an existing Internet phone (terminal) service provider is another provider. The present invention relates to a VIO IP terminal telephone number service method using an Internet phone service provider and a method of converting from a gatekeeper to an IP address so as to be compatible with a phone number user of another terminal using the Internet phone service provider.

In general, telephone calls are made through wired networks, wireless telephones are recently used through wireless networks, and in recent years, the telephone line has been developed to be used for both wired and wireless communication, and internet terminals have become mainstream. The environment is developing forever. 1 is a configuration diagram showing a relationship between a general telephone wired network (A) and an Internet wired network (B), wherein a general telephone wired network (A) provides a circuit through a switched network (PSTN) (1) It comprises a general telephone 12 used by subscribers subscribed to the switching center 11 such as communication. The Internet wired network (B) is a computer 23 which connects to the Internet information provider 21 by a dedicated line through a router 22 provided by an Internet information provider (ISP) 21 such as Cheon Lian, and the other Internet. A packet network 30 constituting the Internet network for internet communication with the information provider 21-1, and a packet network from the Internet information providers 21 and 21-1 are converted into a circuit network method. 1) and a network converter 40 to be connected. They communicate with the subscribers of the general telephone 12 through the switching center 11, and the subscribers subscribed to the Internet information provider 21 request the subscriber number through the Internet information provider 21 and connect to each other. . When connecting to the computer 23 user through a modem through the general telephone 12, the user can connect to the computer 23 having the corresponding IP via the network converter 40 to send and receive mail or to make a call. do.

On the other hand, the wireless network is divided into each area as shown in FIG. 2, the base station 51 to exchange data with the mobile phone 54, the base station center 52 that manages each base station 51 in a predetermined group, Each base station center 52 is configured to include an exchange station 53 that manages the exchange, recognizes customer numbers, etc., checks talk times, and the like. The exchange station 53 may be, for example, SK Telecom 011, and the connection with another exchange station 53-1 (e.g., 017) may be used by transcoding the data so that mutual communication is possible by agreement. Doing.

3 is a configuration diagram in which a wired / wireless network is combined. The wireless network C allows the mobile telephone 54 to make a call through the base station 51, the base station center 52, and the wireless mobile telephone switching center 53, and the switching station. A wired / wireless connection is possible by connecting to a telephone wired network (A) to which a user of a general landline telephone (12) talks and a wired telephone switching center (11) through a wired telephone switching center (11) connected to the telephone network (1). Internet wired network (B) used by the user of the computer 23, for example, a member of the Internet information provider 21, such as a dronenet to enable the Internet by connecting to the packet network 30, The Internet information provider 21 may exemplify a configuration including a network converter 40 for converting the network with the switching center 11.

On the other hand, the network configuration using the Internet terminal is a gatekeeper 26 for recognizing IP addresses, such as computer 23, web phone 24, fish phone 25, and the like through the gatekeeper 26 as shown in FIG. Router 22 for switching a plurality of gatekeeper lines to be shared based on the above, an Internet information provider 21 connected through each router 22, and an Internet packet network provided through the Internet information provider 21. 30,

A line network 1 for connecting the general telephone 12 through the general landline telephone exchange station 11,

The mobile telephone 54 allows a call through the base station 51, the base station center 52, and the wireless mobile telephone switching center 53, and the wireless mobile telephone switching station 53 is also connected to the circuit network 1 so that the general telephone 12 can be connected. A wireless network (C) that allows calls with

The common landline telephone exchange station 11 or the wireless mobile telephone exchange station 53 and the gatekeeper 26 are connected to each other to mutually convert the corresponding telephone number of the general telephone 12 and the mobile telephone 54 and the Internet IP address using the circuit network. Corresponding telephones 12, 54 and the Internet terminal 29, which is made up of a gateway 28 which functions to enable interconnection. In this case, the gateway 28 stores the subscriber IP address of the Internet terminal 29 and the subscriber telephone number using the circuit network 1 at the same time, and stores the subscriber telephone number in the general landline telephone exchange 11 (or wireless (mobile) telephone). Call the desired telephone through the switching center 53 to make a call. That is, the gateway 28 connects to the circuit network 1 based on the telephone number, and when using the packet network 30, which is the Internet network, interconnects based on the IP address. 28 is required to simultaneously store the IP address and the telephone number.

In order to communicate between the PCs 25, which are the Internet terminals, the PC 25 requests the IP address authentication of the PC 25-1 to the gatekeeper 26 as shown in FIG. ). The gatekeeper 26 compares the built-in data to whether the IP of the PC 25-1 can be connected to the PC 25 and informs the PC 25 of whether or not it can be connected (②). Then, the fishponder 25 requests the gatekeeper 26 to set up, and sets up the state of the fishponder 25-1 based on this (3, 4). The fishphone 25-1 then requests authentication from the gatekeeper 26 and the gatekeeper 26 accepts it (⑤, ⑥). After the acceptance is completed, the PC 25 and the PC 25-1 are connected to each other (⑦).

In this case, the fish phone 25 refers to an Internet phone, and the Internet phone (for example, a web phone) is basically interconnected through an Internet IP address. However, the IP (address) is not easy for the general public to remember, and under the LAN environment using the floating IP, the IP often changes, so it is necessary to find out using a program (for example, the "getLocalHost ()" function). Can't. Therefore, in this case, it is difficult for the general public to find the IP unless it is a programmer. In order to solve this problem, in the Internet phone, an easy-to-remember and easy-to-use number similar to the general phone number used by the public has been given in place of IP, and the gatekeeper 26, which is a telephone exchange device of the web phone, is used for actual phone calls. By using the mapping table (IP address and Internet phone number), the IP of the terminal to be called is found and delivered to the web phone. However, the Recommendation (ITU-T) specifies a designated item (field) (E.164 number, e-mail number, alias name) as a telephone number that can be used instead of IP. An example of such a mapping structure is a table as shown in Fig. 6 (having an IP address 61, an alias name 62, an e-mail number 63, a phone number (E.164) 64 and a status 65 field). Can be mentioned.

FIG. 7 is a diagram illustrating a case where there are a plurality of Internet phone service providers shown in FIG. 4, for example, two locations. Each Internet service provider ISP1 and ISP2 adopts a unique Internet phone number. An Internet phone (Internet terminal) subscribed to an Internet service provider (ISP1 or ISP2) can make calls only between subscribers subscribed to the Internet service provider (ISP1 or ISP2), and each Internet service provider (ISP1, Subscribers to ISP2) have a problem that they cannot talk to each other.

The present invention intends to solve this problem. The object of the present invention is to maintain a system in which an Internet phone service provider operating separately collects a usage fee, and each Internet terminal user recognizes an integrated service separately from an individual Internet phone service provider. By implementing a phone number service through the Internet phone number service server, the user can designate the phone number of the Internet phone for the user's convenience.

To this end, the present invention implements an Internet phone number service server that provides an integrated Internet phone number, and when a user applies for registration of an Internet phone number, the gatekeeper converts the application into a recognized Internet phone number system and converts the applied and converted phone number. It is to provide a method of granting an Internet phone number that can be stored and stored up to an Internet phone number.

14 is an overall flowchart of an Internet phone telephone number service server constituting the present invention, in which an applicant for applying for an Internet phone telephone number is connected to an Internet phone number (telephone number) service server through an Internet computer through an individual computer and connected to the web. An initial screen step (P10) functioning to select a menu as shown in FIG. 10 when the initial screen is opened;

When the telephone number new application unit (F1) menu is selected on the initial screen, steps (P21, P22, P30) performed by the server are sequentially performed. The initial screen step (P10) is performed including a phone number registration step according to the Internet phone number new application.

The Internet phone number registration step includes: reading related information including an input of an applied Internet phone number (E164 ID) guided by the user according to the initial screen step (P10) (P21);

Checking whether the read data is existing data, and moving to an initial step (P22);

If it is not the existing data, performing a step (P30) of storing an application Internet telephone number;

The storing step (P30) is a conversion storage step (P31) for converting and storing the applied Internet phone number (E164 DB) to be recognized by the gatekeeper when connecting to the gatekeeper during the Internet phone using the structure variable (s_E164),

Next, using the customer information variable (s_Address) entered by the user, the customer information storage step of storing customer information such as an address (P32),

Payment information storage step (P33) for storing the fee payment information using the service fee payment information variable (s_Bill Info) entered by the user,

And a gatekeeper information storing step (P34) of storing information of the gatekeeper usable as the gatekeeper data using the gatekeeper terminal ID variable s_GK Info.

Specifically, when selecting a new phone number application in the initial screen step (P10), a screen for inputting the information required for the phone number application (for example, Figure 11) appears, after the applicant enters the required information registration button (F12) If you press, read the Internet phone telephone number (e_164) entered by the applicant of the data input on the screen of Figure 11 checks whether the applied phone number is already applied ID (ExistID (e_164)) if the already applied ID " The information message "ID already applied for" is displayed, and the screen returns to the initial screen (P22). If the ID has not been applied for, read all the data entered on the screen of FIG. 11 and store it in the Internet telephone number database (E164DB) shown in FIG. 16A (information required when connecting to the gatekeeper 26 when making an Internet call). After constructing the structure parameter (structure variable) s_E164 of the telephone number conversion and storage function, the parameter is stored as a parameter (P31).

Next, a structure parameter (public information variable) (s_Address) of the customer information database input function for storing in the customer information database (the telephone number (applicant) (E164ID) registrant information applied as shown in FIG. 16D) is constructed and stored ( P32). This information is related to the conversion number applicant ID (E164ID) applied to the customer information database (see FIG. 16D) (resident registration number, customer name, address, zip code, applied ID (E164ID), and ID used by the converted gatekeeper (E164ID). The step of storing (P32).

Next, a structure parameter (service fee payment information variable) (s_BillInfo) of the service fee payment database input function for storing the Internet phone number service fee related information as shown in FIG. 16C is stored in a billing DB. Form a payment database (P33). This is a step of storing information (registration period, payment cost, payment method, requested ID (E164ID), payment date, usage period corresponding to the payment date, etc.) regarding the application period and the charging method of the Internet telephone number service in FIG. 16C. This information is primarily used as back data for Internet phone number service billing.

Next, the structure parameter of the gatekeeper service database input function for storing in the gatekeeper service database (GK Service DB; telephone number (information) (E164ID) and serviceable gatekeeper information) as shown in FIG. A gatekeeper terminal ID variable) (s_GKInfo) is used (P33). This includes information on the gatekeeper that the ID applied to the gatekeeper service database shown in FIG. 16E can use during a call, and there are a plurality of gatekeepers available for one ID. This information is important for the terminal to register with the gatekeeper that can receive optimal service (signal (eg RRQ) for finding and registering a gatekeeper capable of calling at initial startup rather than at the call in the configuration shown in FIG. 5). By providing a terminal, it forms a useful information database that can reduce the amount of network load required to find the gatekeeper when registering the terminal with the gatekeeper.

On the other hand, if you press the registration information change unit (F2) shown in FIG. 10 in the step (P10), the phone number registration information change screen as shown in FIG. 12 appears, in this screen associated with the ID (telephone number) (E164ID) entered by the user. The registered contents are displayed. If any of these information is to be corrected and the contents are corrected and then the registration modification button F22 is pressed, the information is updated in the database related to the telephone number E164ID. On the other hand, if the deregistration button F23 is pressed, the field (isValid) of the database E164DB is changed to "False" so that it is no longer serviced by the Internet phone number service server IPNS.

Meanwhile, when the customer information inquiry unit F3 shown in FIG. 10 is pressed in step P10, a menu screen for customer information inquiry as shown in FIG. 13 appears, and provides registration information inquiry, payment inquiry, and call statistics inquiry function. In this case, when the registration information inquiry unit (F31) button is pressed, information related to the phone number (E164) is displayed, and when the payment information inquiry unit (F32) button is pressed, the payment history such as the period of use, payment date, payment method, amount, and accumulated amount All of this is displayed. In addition, when the call statistics inquiry unit (F33) button is pressed, the call date, call source, call destination, receiver, call time, rate, etc. may be displayed.

FIG. 14 is a flowchart for performing an initial application process of the present invention, and FIG. 15A is a flowchart illustrating an additional number generation method, which is one of the methods of the conversion storage step P31 of FIG. 14, and the function CreateE164 (s_E164. s_id, nid) to convert and generate numbers.

If the first character of the internet phone number requested when applying for the Internet phone number in the function (CreateE164 (s_E164.s_id, nid)) is not a numeric type, converts the character into a numeric format and registers the entire telephone number including the converted number. The process of performing this step may include comparing the Internet telephone number (E164 ID (s_ID)) input by the user (applicant) by one character (Q311).

If it is a character, convert it to an ASCII code value that corresponds to that character (for example, the letter a is ASCII code number 96, and the letter A is ASCII code number 65) to store the converted value. Attaching to a variable nid (Q312),

If it is a number, the addition step (Q313) of adding the number as it is to a variable (nid),

The selected attaching or adding process is repeated by the length of the character of the user input telephone number, and the result is converted to the Internet telephone number (E164 Type ID) value that the gatekeeper can recognize (Q314).

Performing the step (P31) is received as a structure variable (s_E164) including the registration information of the telephone number (E164ID) applying for the data input by the telephone number applicant, the user is a member variable of the structure variable (s_E164) input Converts (nid) a phone number (E164ID (s_E164.s_id)) to a phone number (E164ID) consisting of only numbers that fit within the ITU-T recommendations that the gatekeeper can recognize. There may be various conversion methods for converting the character portion into a number among registered telephone numbers (E164ID). However, here is an example. First, the character of the applicant's Internet telephone number (E164ID) (s_ID) By comparison (Q311),

If it is a character, convert it to the ASCII value corresponding to that character (eg A) (ASCII value (eg A = 65)) (sprintf (nid, "% s% d", nid, (int) c Attach it to a variable (nid) that stores the converted value (Q312),

If it is a number, the number is added to the variable as it is, and the selected attachment or addition process is repeated as long as the character length of the user-entered telephone number (Q314), and the result value is a telephone number that can be recognized by the gatekeeper (E164 Type). ID) (Q31).

Next, the member variable values (resident registration number, customer name, area name, city name, street name, zip code, requested phone number (E164ID)) of the structure variable (s_E164) received as the converted phone number and parameter, and The converted telephone number value nid is stored in the telephone number database E164ID (Q41). That is, even if the user applies for registration by adding letters or numbers to the existing phone number for convenience, the Internet phone number service server 100 internally goes through the steps as shown in FIG. If it is a character, if it is a character, it is stored as ASCII numeric value corresponding to the character to make a database for convenient storage.

FIG. 15B is a flowchart illustrating a process of storing and managing a character in a state in which a character is removed when an additional part added to the beginning of an existing phone number is not a numeric type when registering an application for internet phone number, and the steps Q31, Q41, and Q42 of FIG. Is replaced by).

In a flowchart showing a removal method, which is another method of converting and storing step P31, the additional characters that are added parts of the Internet phone number are removed (step Q31b), and

The structure data (s_E164.id.sid) and the converted ID (nID) value of the generated requested ID (SID) are stored in the Internet telephone number database E164DB (step Q41b).

Then, the process returns to the next step (customer information storage step P32) (Q42b).

That is, if the Internet phone number service server 100 registers the registered Internet phone number of the customer, if the additional part of the phone number constituting the Internet phone phone number is a character, the generation method as shown in FIG. 15A converts the character into an ASCII code and converts the number. Substituting and registering with the Internet conversion number, including, and when the added part (Added Parts) is a text removal method as shown in Figure 15b may be implemented in such a way to store the removed text in a removed state. In this case, the additional unit only confirms whether the Internet phone number is stored and the actual stored data is stored only by the telephone number without the additional unit. That is, two methods, a generation method and a removal method, can be used.

Fig. 17 is a structural example of a mapping table showing an Internet web phone telephone number used in the present invention. Fields constituting the present invention are the IP address 61, the alias name 62, the e-mail number 63, and the telephone number as in the prior art. (E.164) 64 and state 65 fields. However, the present invention has an additional part 100A which adds a web phone recognition code or character to the beginning of an existing element name in the element configuration of the field excluding the IP address 61 and state 65 fields in the elements constituting each field. Make up the configuration. As a preferable example of the addition unit 100A, it is exemplified to add a number (0-9), a letter (＃, *, null) and the like. In this case, if the character is (null), it means the same as the existing telephone number (TelCo No., Mobile Phone No.) system. Of course, you can add additional characters or symbols to the end of the existing phone number element, if necessary. The added number may be extended to two or three digits in addition to a single digit. In addition, when making a call from overseas to domestic and vice versa, a web phone number can be recognized by adding a number or letter for the web phone recognition in front of a country code.

FIG. 18 shows that when an Internet phone (Internet terminal) 29 is registered in the gatekeeper 26 with an Internet phone number given through the Internet phone number service server 100, the other phone or a phone is registered in the registered Internet phone (phone). As a signal flow diagram showing when a telephone call is attempted, the registered Internet telephone number is recognized by the gatekeeper 26 and the actual value of the added value excluded (applied to the exclusion method of FIG. 15B) (creation; applied to the creation method of FIG. 15A) Adress Resolution is performed.

Specifically, the order of the signals that proceed when making a call from the Internet phone 29 to a general phone connected to the Internet network through another Internet phone or gateway 28,

The caller dials the called phone number (Internet phone number; for example # ***-6677) to call the called party.

When the dialing is finished, the Send button is pressed to send an Admission Request (ARQ) to the gatekeeper to find the location of the called party. The message (ARQ) contains the partner's Internet phone number (eg # ***-6677).

When the gatekeeper 26 receives the message ARQ from the caller, the counter phone number checks whether the gatekeeper 26 can intermediate the call connection (ie, a registered terminal) and then the phone number. Finding the IP address corresponding to the address (Address Resolution). In this step, the present invention performs a process of converting the dialed telephone number into a telephone number registered in the gatekeeper 26. After the conversion is made, it is checked whether the converted phone number exists in the gatekeeper service database 115.

If a test result exists, an Admission Confirm (ACF) is sent to the caller. However, if the gatekeeper service database 115 does not exist, it sends a signal ARJ (Admission Reject) to stop the call request.

If the gatekeeper 26 successfully authenticates the other party's phone number, the gatekeeper 26 returns the IP address corresponding to the other party's phone number through a signal (ACF) to the caller. It is a port (Call Signaling Port). Therefore, when the caller receives the call signaling address (Call Signaling Address) of the other phone from the gatekeeper 26 as a signal (ACF), the caller sends a setup message for the telephone connection to the gatekeeper 26.

The gatekeeper 26 relays the setup message received from the caller to the counterpart phone (gateway 26 when the counterpart phone is a regular phone).

After receiving the setup, the other party responds with the signal CONNECT, and the gatekeeper 26 again transmits the connect signal CONNECT to the caller to complete the call setup.

FIG. 19 is a flowchart for performing a method of converting to find an IP address of FIG. 18. When a message (signal) ARQ from a caller terminal arrives at the gatekeeper 26, the gatekeeper 26 is used. In the idle step (S19a) state, the first character of the called phone number that the gatekeeper 26 accepts to find the IP address (Called IP Address) is the Internet telephone number identifier ('#' in FIG. 19). (Step S19b), and if it is an Internet phone number identifier, converts the Internet phone number to the same method as the method used in the phone number registration process (selection of removal method or generation method) (step S19c). ).

The gatekeeper 26 then checks whether the converted number is in the registration table of the gatekeeper 26 and obtains an IP and a port corresponding to the telephone number (step S19d).

On the other hand, if the first character of the other party's phone number is not the Internet phone number identifier in step S19b, the gatekeeper 26 determines the general phone number, and the gatekeeper 26 starts the gateway prefix of the other party's phone number. For example, check the Internet operator designation number (011, 017, etc.) and obtain the phone number from the service table of the gatekeeper 26, and attach it to the front part of the counterpart phone number, and the result is a phone number recognized by the gateway. (Convert US 15628847409 to 65499815628847409, for example) (step S19e). That is, if the other party is an American, the full-length gatekeeper 26, which is dialed at 1 562 8847409 (country code area code telephone number), determines the first one as a US country designation number, and the service table in the gatekeeper 26 is one. The gatekeeper prefix corresponding to '654998' is received through the search and converted into 654998 1 562 8847409.

The gatekeeper 26 then checks whether the gateway prefix is in the gateway service table (step S19f).

In step S19d and S19f, after confirming that the counterpart phone is registered with the gatekeeper 26 or the gateway prefix is found in the gateway service table of the gatekeeper 26, if it is confirmed, a message (ACF; authentication confirmation message signal) If not, a message ARJ is sent to the caller (step S19g).

The present invention described above is not limited to the above-described embodiments and drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be apparent to those who have

As described above, the present invention establishes an Internet phone number service server so that a subscriber using an Internet phone can subscribe to any desired Internet phone number, and the subscriber converts the number into a number when the subscriber requests through the established server. Therefore, Internet phone users who have subscribed to different Internet phone service providers can make mutual calls.

Internet phone number service server checks whether a duplicate subscription when registering the phone number Internet phone number standardization is possible.

In addition, by receiving the gatekeeper information available from the Internet number service server when applying for an Internet phone number, it reduces the time to find the accessible gatekeeper (RRQ) when the terminal starts and reduces the network connection time by reducing the network load.
