Truncation Response Message Processing Method according to Delay Compensation Protocol of Integrated Information Communication Network

摘要

The present invention relates to a delay compensation protocol (DEQ) for delivering broadband data in ISDN, and to a method for processing a truncation response message for a negotiated call between an originating party and a called party.;In the present invention, when the calling party receives the disconnect response message, the presenter determines the current state of the calling party, exchanges predetermined cut primitives between the upper and lower layers according to the cutting request 1 / cutting request 2 state, and then stops all timers of the call requested to be disconnected. And transition the next state to an invalid state. When the called party receives the cut-off response message, it grasps the current state of the called party, stops all timers related to the cut-off call according to the cutting request 1 / cutting request 2 state, and exchanges predetermined cutting primitives between the upper and lower layers of the called party. After that, the next state is changed to invalid state.;Conventionally, there is a disadvantage in that duplicate codes are generated by processing a message (primitive) according to a state transition, and a processing speed is slow. However, the present invention has a similar processing procedure for each state by processing the message (primitive). Or, if they are the same, it is easy to merge these procedures and the code size can be reduced to speed up the processing.
