Abstract

There is disclosed a notification method in a communication system of notifying specific multifunctionality information between terminal stations. An expansion code is generated from both a user input code and a function identification code corresponding to a specific function. A transmission frame including the expansion code is also generated and transmitted to at least one of the terminal stations.
