A method of processing a telephone number response message according to a delay compensation protocol of an integrated information network

摘要

The present invention relates to a delay compensation protocol (DEQ) for transmitting broadband data in an ISDN, and more particularly, to a method for processing a master channel identification message that has arrived at a called party at the time of call setup or additional channel / delete channel setting.;The present invention compares the number of requested channels with the number of telephone numbers when the current state of the calling party that received the telephone number response message is in the telephone number standby state and if the number of requested channels is equal to the number of telephone numbers, = 1 to the entire bandwidth and transits to the initial call setup CID = 1 state. If the required number of channel channels and the number of telephone numbers are not the same, a telephone number request message is sent back to the called party, do.;Conventionally, there is a disadvantage in that a message (primitive) is processed centering on a state transition to generate a redundant code and a processing speed is slow. However, the present invention is based on a message (primitive) If they are similar or identical, it is easy to merge these processing procedures and the code size can be reduced to improve the processing speed.
