BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a call forming technique in an all-IP network, and more particularly, to a call forming method in an all-IP network suitable for preventing hacking due to information exposure with another network.

It is well known that the direction of network development has evolved from the current Circuit Based Separated Network to a Converged Network. In the near future, mobile Internet Protocol (IP) technology will be commercialized and integrated into an "all-IP" network. At the same time, the development of IP-based multimedia will meet the needs of customers. Will be done.

All-IP refers to an IP control system that can add many services in communication to wireless networks, telephones, and other mobile products through the combination of wired and wireless Internet and security of existing IP system. For example, the next-generation video call, the enhancement of the function of the mobile phone and the like.

The definitions and features of the all-IP are briefly described as follows.

Mutual coupling between wireless data networks and Internet networks.

Support for mobile Internet users, including IPv6-based technology called Next Generation Internet Standards.

-Also solved QoS and security problems in IP network.

SIP technology allows mobile users to use multiple applications simultaneously.

-Various kinds of data service can be used in wireless network.

In spite of these features and advantages, a large number of terminals of all-IP networks have a disadvantage in that the possibility of information exposure from a third party is greater than that of a typical wired Internet connection environment. That is, due to the nature of the all-IP network, it can be relatively vulnerable to information exposure because it is integrated with various types of networks.

Therefore, there is a need to develop a technology for ensuring the privacy of customers using the all-IP network and preventing hacking from other nodes (eg, servers, terminals, PCs, etc.).

The present invention has been made in view of the above-mentioned necessity, and when an incoming packet from another IP, for example, voice or data, inflows of all kinds of messages, the sender is displayed by displaying the sender's IP address on the called party's terminal prior to call formation or data communication. It is an object of the present invention to provide a call forming method in an all-IP network that can prevent hacking from another node by allowing a user to determine whether a packet is introduced.

According to a preferred embodiment of the present invention for achieving this object, a call is formed in an all-IP network that performs data communication by interconnecting a calling client and a called client by mutually coupling a wireless data network and an Internet network. A method comprising the steps of: sending IP address information of the calling client to packet destinations, displaying the IP address information of the calling client through the called client, and sending the called client; And forming a call between the calling client and the called client when a call from the user is requested.

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

1 is a schematic block diagram of an all-IP network for implementing a call forming method according to the present invention, in which an originating client (100/1 to 100 / n) and a destination client 104 are all-IP networks. It is composed of a structure interconnected via 102.

As shown in Fig. 1, the calling client 100/1 to 100 / n is a calling mobile terminal, for example, a mobile client such as a cellular phone, a PCS phone, a DMB phone, or a desktop, or a desktop. It refers to a fixed client such as a laptop, and provides a wireless communication service to a subscriber by interfacing with a wireless connection according to the IS-2000 standard, or a wired communication service to a subscriber by interfacing with a wired connection using TCP-IP. That is, due to the emergence of various convergence terminals according to the technology evolution of the terminal, the terminal in which all functions are converged in the all-IP network 102 according to the present embodiment may be applied.

In this case, it is assumed that the calling client 100/1 to 100 / n has IP address information by a unique (or temporary) allocation scheme according to the IPv6 scheme. Such IP address information is IP address information of a desktop or a laptop when the calling client 100/1 to 100 / n is a fixed client, and the calling client 100/1 to 100 / n is a mobile client. In this case, IP address information of a cellular phone, a PCS phone, a DMB phone, and the like is provided. As will be described later, the IP address information of the terminal is provided to the called client 104 via the all-IP network 102.

The all-IP network 102 is a mutual coupling structure between the wireless data network and the Internet network, and supports mobile Internet services including IPv6 based technology called next generation Internet standard. The all-IP network 102 may be configured with an ISP (Internet Service Provider), a gateway, a data location register (DLR), a packet control function (PCF), etc., and the calling client 100 and the called client 104 ) To enable data communication. Detailed configuration and operation of the all-IP network 102 will be described in detail later in the timing chart of FIG. 2.

The destination client 104 may be a mobile client such as (or possessed) a cellular phone, a PCS phone, a DMB phone, or the like. In particular, the called client 104, which is applied to the present embodiment, may caller IP address displaying service (CALs) so that IP address information of the calling client (100/1 to 100 / n) described above can be confirmed. Assume that you are subscribed to).

At this time, only one destination client 104 is shown in the drawing, but this is only for convenience of description, and those skilled in the art can configure a plurality of destination clients 104 connected to the all-IP network 102. It will be easy to see.

Hereinafter, the call forming process in the all-IP network according to the preferred embodiment of the present invention together with the above-described configuration will be described in detail with reference to the timing chart of FIG. 2.

Prior to the description of the call forming process, the all-IP network 102 applied to the present embodiment includes an ISP 102/1, a gateway 102/2, and a DLR 102/3, as shown in FIG. , PCF (102/4).

First, as in step S300, when the calling client 100 requests the call through the incoming number input to the ISP 102/1 (including IP address information of the calling client), the ISP 102/1. Proceeds to step S302 to check the mobile communication provider network of the client corresponding to the called number through the gateway (102/2). That is, the ISP 102/1 checks which network the corresponding terminal exists because heterogeneous compatibility is possible through the gateway 102/2.

When the mobile communication provider network through the gateway 102/2 is confirmed, the gateway 102/2 proceeds to step S304 to check the location (mobile IP information) of the called client through the DLR 102/3. . At this time, the DLR 102/3 confirms that the called client is the calling party IP address indicating service subscriber.

When the location information of the called client and the calling party IP address indication service are confirmed to be subscribers, the DLR 102/3 sends the called PCF 102/4 (or the exchange) the IP address information of the calling client 100 to the called party. Packet data is transmitted (S306).

Accordingly, the PCF 102/4 proceeds to step S308 to attempt data paging to the called client 104 and sends the IP address information of the calling client 100 to the called client 104. Display.

The IP address information of the calling client 100 may be exemplified by a display screen as shown in FIG. 3, for example. In FIG. 3, IP address information of the originating client 100 is illustrated as "150. 23. 25. 31".

In this case, the nickname information of the calling client 100 may be displayed together with the IP address information of the calling client 100 according to the option setting of the called client 104.

Thereafter, when caller confirmation is requested by the called client 104 (S310), the called PCF 102/4 proceeds to step S312 to request to establish a session with the DLR 102/3. This caller verification request is based on the IP address information (and / or nickname) of the calling client displayed on his mobile terminal by the called client 104 subscribed to the calling IP address indicating service. After confirming, it is possible by pressing the call button on the called party's mobile terminal. If the called client 104 does not want to communicate with the calling client 100 and presses the end button, the call is recovered.

If a session is requested from the destination PCF 102/4, the DLR 102/3 proceeds to step S314 to request to establish a packet tunnel of the originating client 100 through the gateway 102/2. do.

The end-to-end packet session is formed by such a packet tunnel formation request, thereby enabling data communication between the calling client 100 and the called client 104 ( S316).

As described above, the present invention transmits IP address information of a mobile client such as a mobile phone as well as a fixed client such as a desktop to the called client as packet data, whereby the called client confirms the IP address information of the calling client. It is an implementation to determine whether to communicate.

According to the present invention, the called client can confirm the calling IP address information and then determine whether the calling client has introduced the packet as needed, thereby ensuring the privacy of the customer using the all-IP network as well as providing other information. Hacking from nodes (servers, terminals, PCs, etc.) can be prevented.

As described above, the embodiments of the present invention have been described in detail, but the present invention is not limited to these embodiments, and various modifications may be made by those skilled in the art within the spirit and scope of the present invention described in the claims below.
