The present invention relates to an ENUM service system in a mobile phone number portability environment, and more particularly, to an ENUM (tElephone NUmber Mapping) service system that provides various connection information and personal information of an individual using a subscriber's telephone number. The first tier locates and delegates the second tier mobile carrier with the mobile carrier identification number, and the second tier searches for the final second tier mobile carrier through NPDB (Number Portability Database) query to perform ENUM query. ENUM service system in the telephone number portability environment.

In general, ENUM (tElephone NUmber Mapping) is a technology that links general public telephone number system (mobile phone number, etc.) with various address systems such as telephone, e-mail, fax, and internet phone to guarantee the commonality and uniqueness of Internet application services. It has been adopted by the International Internet Standardization Organization (IETF) as a standard draft (RFC2916), and is being rushed by countries around the world.

For example, by querying the phone number to the ENUM DB, the subscriber's email, messenger ID, and VoIP address can be inquired. To enable this, a hierarchy of DNS is used (IETF RFC 2916). The standard specification suggests a two-tiered structure, where the first tier analyzes the phone number and plays a role of delivering the inquiry to the appropriate second tier DB, and the second tier defines a structure that stores specific information. The actual configuration should be adapted to the specific circumstances of each country. In Korea, the first tier plays the role of the Korea Internet Information Center (KRNIC) and the second tier plays the role of a mobile operator.

By the way, before mobile phone number portability was enforced, the first layer could analyze only mobile phone operator identifiers (for example, 011, 016, etc.) and delegate the subsequent processing to the mobile phone provider. Not currently in effect.

1 is a block diagram for explaining the configuration of an ENUM service system in a conventional mobile phone number porting environment.

As shown in FIG. 1, the domestic hierarchy of the conventional ENUM service system stores a list of 'number information' and 'corresponding operators' for all subscribers (thousands of millions of telephone numbers) in the first layer, and the second layer stores the first layer. It forms the first layer and the delegation layer and stores the ENUM service information about the subscriber number for each service provider.

However, this can cause a very big problem. First, since the number information and the service provider list of all subscribers are stored in the first tier, the first tier DB becomes excessively large and frequent inquiry requests due to new registration, record modification, etc., degrades performance and is likely to cause errors. There is a growing problem.

In addition, when an error occurs in the first layer DB, there is a problem that a nationwide service paralysis may occur because the number information of all subscribers and the corresponding operator list are stored in the first layer.

In addition, there is a problem that must solve the synchronization between the number portability DB (NPDB) and the ENUM first layer DB between operators for number portability.

The present invention was devised to solve the problems of the prior art as described above. In the ENUM service system which provides various connection information and personal information of an individual using a subscriber's telephone number, the first layer of ENUM is a mobile carrier identification number. The purpose of the present invention is to provide an ENUM service system in a mobile number portability environment where a second-tier mobile carrier can be found and delegated, and the second-tier can find an ultimate second-tier mobile carrier through an NPDB query and perform an ENUM query. There is this.

According to an aspect of the present invention, there is provided an ENUM service system for performing a query and response between an ENUM client and an ENUM DNS server, comprising: a first layer storing an identification number and DNS location information for each mobile carrier; A second layer which forms the delegated layer with the first layer and stores the ENUM service information for the subscriber number; And an NPDB that forms the second layer and the delegation layer and stores the number portability information of the mobile telephone.

In the present invention, the first layer is characterized by analyzing the mobile carrier identification number of the subscriber number and delegates the ENUM service to the second layer of the mobile carrier.

In the present invention, the second layer is characterized by storing separately configured ENUM service information for the subscriber number for each mobile carrier.

In addition, the second layer is characterized in that the ENUM service is delegated from the first layer to identify the mobile carrier of the subscriber number through the mobile phone number portability information of the NPDB.

In the present invention, the NPDB is characterized in that for storing the number portability information of the mobile phone separately configured by the mobile carrier.

In the present invention, the first layer is characterized in that during the ENUM registration checks whether the ENUM number of the registration applicant is correct to perform the authentication and duplicate registration prevention process to determine the final use authority.

In the present invention, the ENUM service information is characterized in that it includes an e-mail, telephone number, homepage address, messenger ID, VoIP for the subscriber number.

As described above, according to the present invention, the first layer of the ENUM service system finds and delegates a mobile carrier of the second layer by a mobile carrier identification number, and the second layer finds a final second layer mobile carrier through an NPDB query and performs an ENUM query. By using the subscriber's telephone number in the mobile phone number portability environment to provide a variety of personal connection information and personal information.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

2 is a block diagram illustrating the configuration of an ENUM service system in a mobile phone number portability environment according to the present invention.

As shown in FIG. 2, the present invention forms a first layer 10 for storing identification numbers and DNS location information for each mobile carrier, and a delegation layer for forming the first layer 10 and an ENUM service for subscriber numbers. And a second layer 20 for storing information, and an NPDB 30 for forming a delegation layer with the second layer 20 and storing number portability information of the mobile telephone.

Here, the first layer 10 is characterized by analyzing the mobile carrier identification number of the subscriber number, and delegates the ENUM service to the second layer 20 of the mobile carrier.

In addition, the first layer is configured to perform an authentication and duplicate registration prevention process for determining the final use authority by checking whether the ENUM number of the registration applicant is correct when registering ENUM.

The second layer 20 separates and stores ENUM service information for the subscriber number for each mobile communication company.

In addition, the second layer 20 is configured to delegate the ENUM service from the first layer 10 and to identify the mobile carrier of the subscriber number through the mobile number portability information of the NPDB 30.

The NPDB 30 separates and stores the number portability information of the mobile telephone for each mobile communication company.

The ENUM service information includes an e-mail, a phone number, a homepage address, a messenger ID, and a voice over internet protocol (VoIP), which is a communication technology that allows a call through the Internet.

As such, the ENUM service system of the present invention can resolve synchronization with the number portability DB 30 between mobile carriers by delegating the ENUM service to the second layer 20 by analyzing only the mobile carrier identification number in the first layer 10. It is.

For example, when an ENUM query (eg, 011-9707-9808: when the identification number is 011 but other mobile carrier subscribers) is requested to the first layer 10, the first layer 10 analyzes only the 011 number and SKT. Pass the query to the second layer 20 of the.

Then, SKT can easily know that the 011-9707-9808 customer has moved the number to KTF by querying its NPDB 30, and again passes the query to the second layer of KTF, resulting in the final query (e.g., wkim@ktf.com) is returned to the original queryer to operate.

As described above, in the present invention, the first layer 10 of the ENUM service system finds and delegates a mobile communication company of the second layer 20 by using a mobile carrier identification number, and the second layer 20 receives the NPDB 30 through the inquiry. By searching for a second-tier 20 mobile carrier and performing an ENUM query, a subscriber's telephone number is used in a mobile phone number portability environment to provide various connection information and personal information of an individual.

As described above, according to the present invention, in the ENUM service system which provides various connection information and personal information of an individual by using a subscriber's telephone number, the first layer of ENUM finds and delegates a mobile carrier of a second layer by a carrier identification number. In addition, the second layer has the advantage of improving the performance of the ENUM service system and reducing the possibility of error by performing the ENUM query by searching for the final second layer mobile carrier through the NPDB query.

In addition, the ENUM service system of the present invention has the advantage of solving the synchronization with the number portability DB between the mobile operators by delegating the ENUM service to the second layer by analyzing only the mobile carrier identification number in the first layer.
