Description

Routing system of next generation network and method

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a routing system and a method of a next generation network (NGN), and more particularly, to an address in a form in which various types of names, numbers, addresses, etc. input by a user in the NGN network can be routed. It is a technology that facilitates communication using various address and number system by converting to.

In general, the next generation communication network is a network that supports traffic such as voice, video, fax, and data to be transmitted through the same link, and is a public switching telephone network (PSTN) network, a cable network, a wireless network, and an Internet Protocol (IP). A separate network such as a network is integrated. Structures and network elements for next generation networks are defined for the purpose of integration and classification of functional layers.

1 is a configuration diagram of a general next generation communication network.

A general next generation communication network includes a terminal 11, 12, a soft switch 13, 14, 15, and a domain name system (DNS) server 16.

When the calling terminal 11 tries to communicate by entering the telephone number E.164, the soft switch 13 connected to the calling terminal 11 accepts the corresponding called terminal 12 corresponding to the telephone number E.164. The host name and termination ID of the soft switch 13 are retrieved and the host name is transmitted to the DNS server 16.

When the DNS server 16 transmits the IP address of the soft switch 15 corresponding to the host name to the soft switch 12, the soft switch 12 is terminated by the soft switch 15 accommodating the destination terminal 12. Attempt communication by sending ID.

As such, in the conventional next-generation communication network, various addressing systems such as a telephone number E.164, an e-mail address, and a SIP URL are input to the calling terminal. These various addressing systems cannot be directly routed, and only IP addresses are used. There is a problem with routing. Therefore, after converting various address systems, such as a telephone number and an e-mail address, input from a soft switch that accepts a destination terminal into an IP address, routing is performed on the IP network.

As such, there is a problem in that a load is placed on the soft switch by performing a task of converting various address systems to IP addresses in the soft switch that accepts the calling terminal.

An object of the present invention for solving the above problems is to facilitate communication between the transmitting and receiving terminals even if a variety of address systems are input in the next-generation communication network.

The present invention for achieving the above object is a plurality of soft switches for accommodating a plurality of communication terminals, name / number translation database for storing the host name and termination ID information of the soft switch corresponding to the address information of the terminal, The host name and the termination ID of the soft switch corresponding to the address information are queried from the name / number translation database by using the address information of the terminal that has requested the name / number translation server and the soft switch corresponding to the host name. Including a DNS server for transmitting an IP address, it characterized in that the communication to the destination terminal corresponding to the termination ID through the soft switch corresponding to the IP address.

The above and other objects and features and advantages of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings.

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

2 is a block diagram of a routing system of a next-generation communication network according to an exemplary embodiment of the present invention.

The routing system of the next generation communication network includes terminals 101 to 106, soft switches 107 to 109, a name / number translation server 110, a name / number translation database 111, and a DNS server 112.

The soft switches 107 to 109 receive address information such as a telephone number, an email address, and a SIP URL of a terminal to be received from the calling terminal, and correspond to the terminal address information to be received by the name / number translation server 110. Request the host name and termination ID of the soft switch. Request the IP address of the soft switch corresponding to the host name of the soft switch received from the name / number translation server 110 to the DNS server 112, the soft switch corresponding to the IP address received from the DNS server 112 Send the termination ID.

The name / number translation server 110 queries the host name and termination ID of the soft switch corresponding to the received address information through the name / number translation database 111.

The name / number translation database 111 stores the host name information of the soft switch and the termination ID information of the terminal for accommodating the terminal corresponding to the address information such as a telephone number and an e-mail address.

The DNS server 112 transmits an IP address corresponding to the host name when receiving the host name from the soft switches 107 to 109.

Hereinafter, a routing method of a routing system of a next generation communication network will be described with reference to FIG. 3.

First, the telephone number or e-mail address (for example, 870-8146, gildong@kt.co.kr) to request communication through the calling terminal 102 is transmitted to the soft switch 107 that accommodates the calling terminal 102. (S100).

The soft switch 107 transmits a phone number or an email address to the name / number translation server 110 (S101), and the name / number translation server 110 receives the phone number or name received from the name / number translation database 112. The hostname of the soft switch 109 (e.g., @ sw3.kt.co.kr) that accepts the destination terminal of the e-mail address and the termination ID (e.g., 1024) that matches the hardware configuration of the soft switch. ) Is searched (S102), and transmitted to the soft switch 107 that accepts the calling terminal (S103). At this time, the information of the soft switch that accommodates the called terminal can be known through the host name, and the called terminal information of the telephone number and email address requested for communication can be known through the transmitted termination ID.

Thereafter, the soft switch 107 transmits the received host name to the DNS server 112 (S104). The DNS server 112 transmits the IP address (for example, 147.6.90.90) of the soft switch 109 corresponding to the received host name to the soft switch 107 accommodating the calling terminal 102 (S106). .

The soft switch 107 transmits the termination ID to the soft switch 109 corresponding to the received IP address, and communicates to the called terminal 105 corresponding to the termination ID among the terminals accommodated by the soft switch 109. To try (S107).

As such, when the calling terminal attempts to communicate with the receiving terminal in the NGN network, the present invention attempts to communicate by converting a variety of convenient address systems into IP addresses instead of IP addresses through the name / number translation server 110. To help.

As described above, the present invention has the effect that the caller can conveniently communicate by using a variety of caller's address system in the next-generation communication network.

In addition, the preferred embodiment of the present invention for the purpose of illustration, those skilled in the art will be able to various modifications, changes, replacements and additions through the spirit and scope of the appended claims, such modifications and changes are the following claims Should be seen as belonging to.
