Description

Apparatus and method for multiple automatic test of internet gateway system

The present invention relates to a multi-automatic test apparatus and method thereof of the Internet gateway system, and in particular, to configure the Internet gateway system ITGS (Internet Telephony Gateway System) or VoIP (Voice over IP) system in multiple to be suitable for automatic testing The present invention relates to a multi-automatic test apparatus and a method of an internet gateway system.

In general, the Internet gateway system is ITGS or VoIP.

Voice over Internet Protocol (VoIP) is a term that refers to IP telephony technology for a series of facilities that transmit voice information using IP. This means that voice information is sent in digital form within discrete packets, rather than traditional protocols based on circuits such as PSTN, a public switched telephone network. The main advantage of VoIP and Internet telephony technology is that it integrates telephone service by utilizing existing IP network, allowing telephone users to receive long-distance and international phone service in internet and intranet environment with only local call charge.

VoIP encourages the use of ITU-T H.323, a standard for transporting voice (sound) and video over IP over the public Internet or intra-company intranets, through Cisco, Vocaltec, 3Com, and Net. This was done by efforts by major equipment manufacturers, including Speak. The VoIP Forum also encouraged directory service standards, enabling users to locate other users and enabling the use of touch phone signals for automatic telephone distribution and voicemail.

In addition to the original IP functionality, VoIP uses a real-time protocol (RTP) to support packets arriving in a timely manner. Using public networks, it is currently difficult to guarantee quality of service (QoS). Better service can be achieved by using a private company or a private network managed by an Internet Telephone Service Provider (ITSP). The technique used by equipment makers, called NetSpeak, to ensure fast packet forwarding, surfs to all network gateways connected to the public network before establishing a TCP socket connection with the other party, and based on the results, To choose.

To use VoIP, companies must install VoIP equipment, such as Cisco's AS5300 Access Server, on the gateway. The gateway receives voice transmissions broken up into packets from users in the company and either sends them to other parts of the intranet or sends them to the PSTN using the T-1 or E1 interface.

Therefore, there are two methods to test the conventional ITGS / VoIP system.

First, a test system is constructed like a real service environment, and a tester generates a call by interworking a test ITGS / VoIP system (hereinafter referred to as a "test system") and a reference ITGS / VoIP system (hereinafter referred to as a "reference system"). To do.

The second is to test using a special test device ("Test Device"), in which case one system under test and one reference system were necessary.
