Abstract

PURPOSE:To eliminate the necessity of busy waiting by constituting a group with terminal devices such as plural telephone sets and, connecting to other terminal device in the same group automatically, when the terminal device concerned is busy. CONSTITUTION:A group is constituted by terminal devices 11-1n. When the connection between terminal device 11 and terminal device 1n is requested, a controlling device 2 checks whether the terminal device 1n is busy or not. If the terminal device 1n is not busy, the terminal device 11 is connected to the terminal device 1n. When the terminal device 1n is busy, the controlling device 2 searches for an empty terminal device from the terminal devices 12-1n-1in the same group. If the terminal device 1n-1 is empty is searched, for example, the terminal device 11 is connected to the terminal device 1n-1. Thus, even if the terminal device concerned is busy, and other empty terminal device is connected, reducing the necessity of waiting.
