Problems solved by technology

[0010] However, the above-mentioned conventional technology establishes an independent call control mode between the PSTN terminal and the IP network terminal, because the PSTN terminal and the IP network terminal are designed with independent system
Therefore, the PSTN terminal and the IP network terminal perform functions different from each other, so that it is difficult to complete the integration of the IP terminal in one area or one building where the existing PSTN is used.
In other words, in implementing an IP-based PBX, the conventional technology cannot control the call of an IP terminal in the same manner as an extension user, so that it cannot use various extension functions provided in the PBX

Embodiment Construction

[0022] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. In the drawings, identical or similar elements described in different drawings are denoted by the same reference numerals. In the following description, a detailed description of known functions and configurations introduced herein will be omitted when it may make the subject matter of the present invention unclear.

[0023] figure 1 A block diagram of a network telephone exchange system according to a preferred embodiment of the present invention is shown. refer to figure 1 , the IP-PBX 14, which is mainly used to switch call paths of multiple traditional terminals 16, is connected to the PSTN 10 through an intra-office line trunk card (or circuit board) (not shown). This intra-office line trunk card is well known to those skilled in the art as interfaces with E1 / T1, PRI (primary rate interface), BRI (basic rate interface) and No. 7 signaling system, etc...

Abstract

An Internet Protocol telephony exchange system and a call control method thereof. The exchange system integrates an IP terminal and a legacy terminal in a single exchange system, controls a call of the IP terminal in the same manner as an extension subscriber, and contains at least one IP terminal connected to the IP network. The IP terminal contains a user interface for generating user information or converting received user interface information into information of a user-identifiable state, and performs a VoIP function in compliance with one or more of a H.323, a MGCP and an SIP protocol procedure. The IP network is connected to an IP driver and an IP-PBX (Internet Protocol-Private Branch Exchange). The IP driver controls an IP end point at which the IP terminals are positioned, upon receiving IP terminal connection information and call control information based on H.323 / MGCP / SIP protocol procedure.

Description

[0001] This application claims priority to a patent application entitled "Internet Telephony Switching System and Call Control Method Thereof", filed with the Korean Intellectual Property Office on October 13, 2001, No. 2001-63192, the contents of which are hereby Incorporated by reference. technical field [0002] The invention relates to a dedicated exchange system, in particular to a network telephone exchange system. Background technique [0003] In recent years, following the trend of rapid development of Internet technology, various service demands and IP-based networks are rapidly increasing not only in Internet performance but also in Internet service. For example, voice transmission over IP networks is one of various services. VoIP (Voice over Internet Protocol) supports this voice signal transmission over IP networks. Data transmission is usually considered to implement an IP network, but at present it is necessary to consider both voice transmission and data tra...
