Description

How to send connection and control message between gateway and management operating system

The present invention relates to a method of transmitting a connection and control message between a gateway and a management operating system, and a computer-readable recording medium having recorded thereon a program for realizing the same.

Currently, various methods are used to transmit access and control messages between the Internet phone gateway and the management operation system. The first is a method based on the International Telecommunication Union (ITU) standard, and the method of communication by accepting H.225 (RAS message) of H.323, which is the most used in the Internet phone standard. It is a method of defining a communication method between systems and transmitting a connection and control message using the method.

Each method has its advantages and disadvantages. The first method enables communication between the management operating system and the heterogeneous gateway, while requiring a lot of computational resources to accommodate the standard, which leads to an increase in the price of the gateway and management operating system equipment. More time is required to transmit the connection and control messages between the gateway and the management operation system, and there is a disadvantage of increasing the connection delay time after dialing when using an Internet phone. The second method has the disadvantage that only communication between a specific gateway and a management operating system is possible, while applying a specific connection and control message transmission method reduces the computer resources required for the Internet phone gateway and management operating system and reduces the connection time after dialing. Can be.

Therefore, considering interoperability with other gateways to easily accommodate standards, simplifying communication between gateways and management operation systems, using less computational resources, and reducing access delay time after dialing by performing fast access and efficient control data transmission. How to do this is required.

Accordingly, the present invention has been made to meet the above requirements, and records a connection and control message transmission method for transmitting a connection and control message for reducing connection delay time between a gateway and a management operation system, and a program for realizing the same. Its purpose is to provide a computer readable recording medium.
