Description

Internet Protocol Phone System and Automatic Method of Internet Protocol Phone Terminal Authentication and Phone Number Assignment Using the System [Internet Protocol Phone System and Internet Protocol Phone Device and Phone Number Assignment Method}

The present invention relates to a media access control (MAC: Media Access Control, MAC) in an Internet protocol (IP: Internet Protocol, hereinafter called IP) phone system using VIP (VoIP: Voice over Internet Protocol). The present invention relates to an IP phone system for assigning an address to each IP phone terminal and performing authentication and automatic phone number assignment of the IP phone terminal, and an IP phone terminal authentication and phone number automatic allocation method using the same.

In general, VoIP refers to IP telephony technology for a series of facilities that use IP to convey voice information, which is typically not traditional protocols based on circuits, such as Public Switched Telephone Networks (PSTNs), The exchange of voice information in digital form within discrete packets.

The H.323 protocol is an ITU-T (International Telecommunications Union-Telecommunication Standardization Sector) for transmitting video data, especially for multimedia video conferencing, through a packet switched network such as TCP / IP. Is the standard protocol.

IP phone system is a system that provides users with telephone service using VoIP such as H.323 protocol. IP phone system can be used alone, but it is not easy to use because it is too inconvenient to use. Usually used in conjunction with a gatekeeper.

As shown in the drawing, a conventional IP phone system includes a plurality of IP phone terminals 20 each having a unique number and a gatekeeper which performs a server function of registering and managing numbers of the plurality of IP phone terminals 20. Gate Keeper (10) and a gateway (Gateway, 30) for connecting to the existing PSTN (40), the components 10 to 30 are interworked through the LAN line (50) or the like.

At this time, in order to use each IP phone terminal 20, the authentication process of the gatekeeper 10 must be performed. For this reason, if there is no authentication procedure, the gatekeeper 10 is an IP phone terminal to be serviced by the IP phone terminal. This is because it is difficult to distinguish whether or not the phone terminal 20, and accordingly, it is difficult to charge for the call because it provides any IP phone terminal or service.

In this way, in order to facilitate the charge of the call cost, the gatekeeper 10 confirms the IP phone terminal 20 registered therein through the authentication procedure, and then connects the call to the corresponding IP phone terminal 20.

Methods of performing such an authentication procedure include a method of authenticating using the H.323 protocol ID of the IP phone terminal 20 and a method of authenticating using an IP address.

However, in both methods using the H.323 protocol ID or IP address, an administrator or an IP phone user 20 uses a predetermined authentication input procedure to perform authentication at the gatekeeper 10 and the IP phone terminal 20. There is a problem that has to be done.

In addition, the method of using an IP address has a problem that authentication itself becomes difficult in a system using a dynamic host configuration protocol (DHCP), which uses a dynamic IP whose IP address changes with time. Will occur.

The present invention was devised to solve these problems, and in an IP phone system using VoIP, an IP phone capable of assigning a MAC address to each ID phone terminal and performing authentication and automatic phone number assignment of the IP phone terminal through it By providing the system and IP phone terminal authentication and automatic telephone number assignment method using the system, it is possible to prevent the occurrence of any IP phone terminal at the same time while eliminating the inconvenience of the authentication input process that occurs when the user uses the IP phone, Its purpose is to enable certification to be performed regardless of whether or not the variance is changed.
