The present invention relates to a method for automatically registering ENUM subscriber information, and more particularly, to a method for automatically registering subscriber's telephone number and IP address as well as additional information in an ENUM DNS server.

Due to the recent development of internet technology, communication technology using analog signals is also changing to internet based technology. In addition, information on subscribers is easily available due to the development of VoIP (Voice of IP) technology, navigation technology, internet banking technology, security authentication technology, video technology, e-mail technology, and UCC (User Created Contents) technology. There is a demand for it.

Accordingly, various Internet address systems are being researched and developed to support the convenience of users as well as the explosive increase in Internet usage and activation of electronic commerce services around the world. However, the internet address systems developed through such continuous research can support various services. However, since the separate research was conducted for each service, user confusion and address resource management became more difficult.

In order to solve this problem, ENUM (tElephone Number Mapping), which integrates various existing Internet application services into one identification system and links the public public telephone number system that can guarantee commonality and uniqueness with the Internet address system , Hereinafter referred to as 'ENUM'.

Here, ENUM is an Internet protocol defined in IETF RFC 2916. It uses an E.164 phone number of ITU-T, which is guaranteed globally, as an identifier, and is referred to as a public switched telephone network (PSTN). Connection) and the Internet Protocol (IP) network.

In other words, ENUM is a next-generation identification system that connects telephone and internet, the most important means of communication in modern society, by integrating various communication services using 12-digit telephone number.

ENUM maps a person's phone number to an Internet address in the same way that a domain name, a concept of Domain Name System (DNS), is mapped to a network. That is, ENUM has a hierarchical structure based on Internet DNS for mapping phone numbers to attributes such as Uniform Resource Indicator (URI).

ENUM can replace your home phone number, office phone number, fax number, mobile phone number, and email address with a single phone number. In other words, phone numbers and Internet addresses work on a single system, so when you enter a phone number on your computer, you can connect to a variety of communication services such as Internet homepages, emails, faxes, mobile phones, and instant messages.

For example, when a user inputs an identification number for the other party (for example, a phone number assigned to the other party) to an ENUM service providing terminal, the identification number is converted from the ENUM DNS server to an Internet address system corresponding to the other party's identification number. The mobile phone number, the fax number, and the e-mail address information stored in the ENUM DNS server may be read and transmitted to the user's terminal. Thereafter, the user may be provided with various services (eg, email transmission, fax transmission, cellular communication, etc.) to the counterpart by selecting a desired menu.

However, it is inconvenient that the subscriber needs to input additional information (for example, a mobile phone number, a fax number, etc.) corresponding to the identification number described above or use a separate recording means.

1A is a conceptual view of providing a service using ENUM according to the related art. More specifically, the first terminal subscribed to the first service providing server and the second terminal subscribed to the second service providing server describe the concept of using the ENUM service to receive a certain service.

Referring to FIG. 1, the overall system includes a first terminal 110, a first service providing server 120, an ENUM DNS server 130, a second service providing server 140, and a second terminal 150. have.

First, the first terminal 110 and the second terminal 150 may include a wired terminal and a wireless terminal. For example, the first terminal 10 and the second terminal 50 may be a mobile phone, a PDA, a laptop capable of wired and wireless communication.

In addition, the first terminal 10 and the second terminal 50 may be an Internet program that can be implemented on a computer. In general, the Internet program converts a signal input from the first terminal 10 to transmit a voice signal or a data signal to the second terminal 50. Of course, it will be apparent that a computer may include an input / output device in order to implement the above-described Internet program.

In particular, it is obvious that the term 'terminal' is not limited to mechanical means but may mean a user who owns a terminal or receives a certain service using the terminal.

In FIG. 1, the first terminal 110 subscribed to the first service providing server and the second terminal 150 subscribed to the second service providing server receive ENUM DNS to receive a certain service. The concept of using a server is described.

In particular, the case where the first terminal 110 intends to use the Internet terminal service with the second terminal 150 will be described. First, the first terminal 110 may transmit an identification number corresponding to the second terminal 150 to the first service providing server 120.

At this time, the first service providing server 120 transfers the identification number (eg, '82 -2-100-1234 ') of the second terminal 150 transmitted from the first terminal 110 to a certain ENUM scheme. It is converted into a corresponding format (eg, '4.3.2.1.0.0.1.2.2.8.e164.arpa': 'Internet identifier') and forwarded to the ENUM DNS server 130.

Accordingly, the ENUM DNS server 130 recognizes the Internet identifier corresponding to the second terminal 150 described above, and the information about the second terminal 150 (for example, a homepage address, an Internet phone number, an e-mail address, a general address). Phone number, mobile phone number, and fax number) may be read and delivered back to the first service provider 120.

Thereafter, the first service providing server 120 may receive the Internet phone number of the second terminal 150 and request the service providing to the second service providing server 140 using the received Internet telephone number. Accordingly, the second service providing server 140 may perform a predetermined procedure so that the first terminal 110 and the second terminal 150 can use the Internet telephony service.

As a result, the first terminal 110 can be provided with the Internet phone service using a unique identification number corresponding to the second terminal 150.

Of course, the identification number is not limited to the second terminal and is a unique number uniquely assigned to the user who owns the second terminal as described above.

That is, the first terminal 110 and the second terminal 150 may transmit an e-mail or a fax between both parties using an identification number.

In particular, in the description of FIG. 1A, the first terminal 110 is connected to the first service providing server 120 and the second terminal 150 is connected to the second service providing server 140. It will be apparent that the same principle may be applied to the same service providing server and not a separate service providing server.

1B is a conceptual view of providing a service using another ENUM according to the related art. Since the method of using the ENUM service for FIG. 1B is generally similar to the method described with reference to FIG. 1A, the following description will focus on differences from FIG. 1A.

It is assumed that the first terminal 110 and the second terminal 150 are connected to the same service providing server.

As in the case of FIG. 1A, the first terminal 110 transmits an identification number corresponding to the second terminal 150 to the service providing server 160, and the service providing server 160 of the second terminal corresponding to the identification number. The internet identifier may be transmitted to the ENUM DNS server 130.

 Accordingly, the ENUM DNS server 130 may transmit information (eg, home page address, e-mail address, mobile phone number, fax number, etc.) corresponding to the second terminal to the service providing server 160.

Thereafter, the service providing server 160 transmits the information corresponding to the second terminal 150 to the first terminal 110 again. Accordingly, the first terminal 110 may select a service to be used together with the second terminal 150 from the transmitted and output information. Accordingly, the service providing server 160 provides the selected service to the first terminal 110 and the second terminal 150.

However, the ENUM DNS server 130 described with reference to FIGS. 1A and 1B has a problem that subscriber various information must be stored from a subscriber or a service provider.

Such manual data modification and update not only correspond to the rapidly changing communication service, but also cause confusion to subscribers, making it unsuitable for next-generation communication and Internet systems that provide communication service with a unique identification number.

That is, in order to utilize the ENUM service, there is a problem that a subscriber or a service provider manually stores information corresponding to a large number of subscribers in an ENUM DNS server.

Accordingly, an object of the present invention for solving the above problems is to provide a method for automatically registering subscriber information in an ENUM DNS server.

Another object of the present invention is to provide an automatic subscriber information registration method that can solve the economic problem of manually inputting subscriber information by automatically registering subscriber information in an ENUM DNS server.

Request for an update by transferring to a DNS (Domain Name System, hereinafter referred to as 'DNS') server, each of the steps may be performed in the service providing server.

Here, step (b) may further include transmitting an authentication request signal for the terminal to the information providing server.

In addition, step (c) may further include receiving an authentication response signal for the terminal from the information providing server.

In addition, in the step (d), the identification number may be characterized in that converted to the Internet identifier of the format used in the ENUM DNS server and transmitted to the ENUM DNS server.

The above-described invention may further include (e) receiving a subscriber information update response signal of the terminal from the ENUM DNS server.

The step (a) may further include receiving an identification number of the counterpart terminal from the terminal.

Step (d) may further include transmitting the identification number of the counterpart terminal to the ENUM DNS server.

The method may further include receiving subscriber information corresponding to the identification number of the counterpart terminal from the ENUM DNS server.

Here, the subscriber information may include at least one of an IP address, a telephone number, a mobile phone number, a fax number, an e-mail address, a homepage address, and a URL corresponding to the terminal.

In this case, the information providing server may be an AAA (Authentication Authorization Accounting) server.

Here, the service providing server is at least any one of SGSN (hereinafter referred to as 'SGSN'), GGSN (called Gateway GPRS Support Node or 'GGSN'), and HA (Home Agent (hereinafter referred to as 'HA')). It may include one.

The description will be omitted.

2 is a conceptual diagram illustrating a method of providing an ENUM service according to an embodiment of the present invention. More specifically, FIG. 2 is a diagram illustrating a method in which a terminal receives a desired service from the ENUM DNS server 150 according to an embodiment of the present invention.

First, a system for explaining an ENUM service providing method includes a terminal 170, a service providing server 160, and an ENUM DNS server 130.

The terminal 170 may be a generic term for the first terminal 110 and the second terminal 120 described with reference to FIGS. 1A and 1B. That is, when the terminal 170 uses the ENUM service alone, it may be either the first terminal 110 or the second terminal 150. In addition, when the first terminal 110 and the second terminal 150 simultaneously use the ENUM service, the terminal 170 may collectively refer to the first terminal 110 and the second terminal 150. In addition, it will be apparent that a terminal capable of receiving the ENUM service may request an integrated communication service through wired and wireless communication networks.

Hereinafter, the ENUM service providing method will be described in detail.

In step S210, the terminal 170 may transmit the identification number of the counterpart of the service to the service providing server 160. Of course, in the service providing server 160, an identification number corresponding to the terminal 170, which is a subject that always uses a service, may be automatically transmitted together with the other party's identification number. Self-explanatory In the following steps, it will be described on the premise that the identification number corresponding to the terminal 170 requesting the service is always delivered with the service request signal.

In step S220, the service providing server 160 that has received the counterpart's identification number may convert the counterpart's identification number into an internet identifier of a format corresponding to the ENUM service provision and transmit the counterpart's identification number to the ENUM DNS server 130.

Of course, it is apparent that the identification number of the terminal and the counterpart identification number of the above-described terminal may be transmitted to the ENUM DNS server 130 when a separate conversion process is not required. Hereinafter, a description will be given based on a system requiring an identification number and an internet identifier separately.

In step S230, the ENUM DNS server 130 may read the subscriber information of the counterpart corresponding to the above-described Internet identifier from the storage unit and transfer the subscriber information to the service providing server 160.

Here, the subscriber information refers to an IP address, a phone number, a mobile phone number, an e-mail address, a homepage address, and a mobile IP corresponding to the terminal (herein, the first terminal and the second terminal, etc.) 110, 150, and 170. Address, URL, and the like.

In step S240, the service providing server 160 may transfer the subscriber information of the counterpart received from the ENUM DNS server 130 to the terminal 170 again. Of course, it will be apparent that the subscriber information of the other party to be delivered to the terminal may be transmitted in various communication methods (for example, wired / wireless Internet-based data transmission methods).

In step S250, the terminal 170 may request the service providing server 160 for a desired service by using the received subscriber's subscriber information. For example, when requesting an email service, the terminal 170 may request an email service from the service providing server 130 using an email address among subscriber information of the counterpart.

In step S260, the terminal 170 may provide a service corresponding to the service request transmitted from the terminal 170.

3 is a conceptual diagram of a method for providing an ENUM service according to another embodiment of the present invention. In more detail, unlike the embodiment described with reference to FIG. 2, the case in which the identification number and the service request of the second terminal 150 are transmitted to the service providing server 160 will be described.

In operation S310, the first terminal 110 may provide an identification number of the first terminal 110, an identification number corresponding to the second terminal 150, and a request signal for a service to be provided. To pass on.

In operation S320, the service providing server 160 may convert the received identification number of the second terminal 150 into an Internet identifier of a format corresponding to the ENUM service provision and transmit the converted ID to the ENUM DNS server 130.

In step S330, the ENUM DNS server 130 is subscriber information of the second terminal 150 corresponding to the above-described Internet identifier (for example, IP address, telephone number, mobile phone number, etc. corresponding to the counterpart terminal) This can be read from the storage and delivered to the service providing server 160. Here, the storage unit may be included in the ENUM DNS server 130 or separately provided and connected to the ENUM DNS server 130.

In operation S340, the service providing server 160 may provide a service requested from the first terminal 110 using subscriber information of the second terminal 150 received from the ENUM DNS server 130. For example, when a fax service request is transmitted from the first terminal 110 to the second terminal 150, the service providing server 160 may determine the second terminal 150 delivered from the ENUM DNS server 130. Fax service can be provided using the fax telephone number included in the subscriber information.

4 is a conceptual diagram of a method for automatically registering ENUM subscriber information according to a first embodiment of the present invention. More specifically, a method of automatically registering subscriber information stored in the ENUM DNS server 130 described with reference to FIGS. 2 and 3 will be described.

In general, the subscriber using the terminal has a problem in that the subscriber information needs to be stored in the ENUM DNS server 130 as well as the server 180 providing the subscriber information and the subscriber information to the service providing server.

The system according to the first embodiment of the present invention is composed of a terminal 170, a service providing server 160, an information providing server 180, and an ENUM DNS server 130.

In step S410, the terminal 170 may transmit the identification number and the counterpart identification number of the terminal 170 to the service providing server 160. In FIG. 4, it is assumed that the terminal 170 does not make a separate request for a corresponding service.

In operation S420, the service providing server 160 may transmit the identification number of the terminal 170 to the information providing server 180.

In this case, the identification number corresponding to the terminal 170 may be generally transmitted to the service providing server 160 as described above.

In step S430, when the terminal 170 is authenticated as a subscriber, the information providing server 180 may transmit an authentication response signal indicating completion of authentication and subscriber information corresponding to the terminal 170 to the service providing server 160. have.

In operation S440, the service providing server 160 may transmit the identification number, subscriber information, and counterpart identification number of the terminal 170 to the ENUM DNS server 130. Of course, when separate conversion of the above-described terminal identification number and the counterpart identification number is necessary, the Internet identifier corresponding to the ENUM service may be transmitted to the ENUM DNS server 130, of course.

In step S450, first, the ENUM DNS server 130 may update the subscriber information of the user of the terminal 170 by using the subscriber information of the user transferred from the service providing server 160.

In addition, the ENUM DNS server 130 may read the other party's subscriber information by using the other party's Internet identifier transmitted from the service providing server 160.

Accordingly, the ENUM DNS server 130 may transmit the subscriber information update response signal of the user and the subscriber information of the counterpart to the service providing server 160.

In operation S460, the service providing server 160 may transmit subscriber information of the other party to the terminal 170.

In step S470, the terminal 170 may transmit a signal for requesting a desired service to the service providing server 160 using subscriber information of the counterpart.

In operation S480, the service providing server 160 may provide the terminal 170 with a service corresponding to the transferred service request signal.

Here, the information providing server 180 is a server that determines whether or not the subscriber requesting to provide a service using the subscriber's identification number. For example, the information providing server 180 may be an authentication charging (Authentication, Authorization and Accounting, hereinafter 'AAA') server.

The information providing server 180 may store subscriber information corresponding to the terminal 170. That is, the information providing server 180 may update the subscriber information in real time as well as whether the subscriber is authenticated.

In addition, the authentication procedure for the terminal 170 described above may be performed in a server separate from the information providing server 180. In particular, when the service providing server 180 performs the authentication procedure for the terminal 170, it will be obvious that no separate authentication procedure is required. That is, the authentication procedure required in steps S420 and S430 may not be separately performed. However, the information providing server 180 to be described below will be described on the premise that the authentication procedure for the user is also performed.

Of course, the service providing server 160 may update the information providing server 180 based on information that the subscriber separately changes in order to use the service providing server 160.

Here, the service providing server 160 may be a server that provides various services. For example, it may be a fax transmission server, a prepaid card call service providing server, or the like.

Here, it will be apparent that the service provided by the service providing server 160 to the terminal may be performed separately from the subscriber information update process such as S440.

5 is a conceptual diagram of a method for automatically registering ENUM subscriber information according to a second embodiment of the present invention.

The system according to the second embodiment of the present invention includes a first terminal 110, a service providing server 160, an information providing server 180, an ENUM DNS server 130, and a second terminal 150.

In step S510, the first terminal 110 may transmit the identification number of the first terminal 110, the identification number of the second terminal 150, and a desired service request signal to the service providing server 160. Here, the service requested by the first terminal 110 may be wireless communication or wireless internet communication with the second terminal 150.

In operation S520, the service providing server 160 may transmit the identification number and the authentication request signal of the first terminal 110 to the information providing server 180.

Here, as described above, the identification number corresponding to the first terminal 110 may be generally transmitted to the service providing server 160. Of course, when authentication is not required, only the identification number of the first terminal 110 may be transmitted to the information providing server 180.

In step S530, when the first terminal 110 is authenticated as a subscriber, the information providing server 180 transmits an authentication response signal indicating completion of authentication and subscriber information of the first terminal 110 to the service providing server 160. I can deliver it.

In operation S540, the service providing server 160 may transmit the identification number of the first terminal 110, the subscriber information, and the identification number of the second terminal 150 to the ENUM DNS server 130. Of course, as described above, when a separate conversion process is required, the counterpart internet identifier converted into the ENUM service format may be transmitted to the ENUM DNS server 130.

In step S550, first, the ENUM DNS server 130 may update the subscriber information of the first terminal 110 transmitted from the service providing server 160.

In addition, the ENUM DNS server 130 may read subscriber information of the second terminal 150 using the Internet identifier of the second terminal 150 transmitted from the service providing server 160.

Accordingly, the ENUM DNS server 130 may transmit the subscriber information update response signal of the first terminal 110 and the subscriber information of the second terminal 150 to the service providing server 160.

In operation S560, the service providing server 160 may transmit subscriber information of the second terminal 150 to the first terminal 110.

Accordingly, the service providing server 160 may extract information corresponding to the requested service from the first terminal 110 from the subscriber information of the second terminal 150 and provide the corresponding service to the first terminal 110. .

For example, as described above, the first terminal 110 may use the Internet terminal service with the second terminal 150.

6 is a conceptual diagram of a method for automatically registering ENUM subscriber information using a wireless network access service according to a third embodiment of the present invention. In more detail,

The system for automatic registration of subscriber information performed in FIG. 6 includes a terminal 170, SGSN (hereinafter referred to as a 'Serving GPRS Support Node' SGSN ') 190-1, and GGSN (hereinafter referred to as a Gateway GPRS Support Node (GGSN)). 190-2, the information providing server 180 and the ENUM DNS server 130 may be configured.

In step S610, the terminal 170 may be connected to the SGSN 190-1 to connect to the wireless network. Here, SGSN 190-1 is a node in charge of data packet transmission with a mobile station in a wireless service area.

In step S620, the SGSN 190-1 may receive a call signal transmitted by the terminal 170 connected to the wireless network and transmit the received call signal to the GGSN 190-2. Here, the GGSN 190-2 may be a gateway device for sending packet data received from the SGSN 190-1 to the Internet.

In step S630, the GGSN 190-2 may transmit whether to authenticate the subscriber corresponding to the terminal 170 to the information providing server 180. Of course, as described above, the identification number of the terminal 170 may be transmitted to the information providing server 180 to determine whether the subscriber is authenticated.

In step S640, when the authentication for the terminal 170 is completed, the information providing server 180 may transmit the authentication response signal and the subscriber information of the terminal 170 to the GGSN 190-2.

In step S650, the GGSN 190-2 may provide a wireless communication service requested by the terminal 170. In addition, the wireless communication service does not need to be performed after step S640 will be apparent in view of the technical spirit to which the present invention belongs.

In step S660, the GGSN 190-2 may transmit an update request signal for subscriber information transmitted from the information providing server 170.

In operation S670, the information providing server 170 may transmit an update response signal indicating that the update of the subscription information corresponding to the terminal 170 is completed to the GGSN 190-2.

The third embodiment of the present invention illustrated in FIG. 6 has been described on the premise that the terminal 170 uses a wideband code division multiple access (WCDMA) scheme. On the contrary, when the terminal 170 requests a call connection using a code division multiple access (CDMA) scheme, the SGSN 190-1 may use a GGSN as a PCF (Point Coordinator Function). 190-2 may be changed to a PSDN (Packet Data Serving Node, hereinafter referred to as 'PSDN').

In the following description, a fourth embodiment according to the present invention in FIG. 7 will be described in a case in which a step of requesting mobile IP registration in the terminal 170 is added according to a policy of the service providing server 160. Of course, as described in FIG. 6, it will be apparent that the terminal 170 may use various services using the dynamic mobile IP address as well as the various services using the static IP address.

7 is a conceptual diagram of a method for automatically registering ENUM subscriber information when using a mobile IP registration service according to a fourth embodiment of the present invention.

The system for automatic registration of subscriber information performed in FIG. 7 includes a terminal 170, SGSN 190-1, GGSN 190-2, HA 190-3, an information provision server 180, and an ENUM DNS server ( 130).

Since steps S710, S715, S720, S755, and S760 are performed corresponding to steps S610, S620, S650, S660, and S670, respectively, description thereof will be omitted.
