Abstract

A service method of connection management for a communication line is established to perform a desired connection of the communication line in accordance with a telephone caller's request when the caller wants to be connected to a called person by way of the communication line. The method includes the steps of: detecting whether or not the communication line is crowded; measuring a passed time of a connected state of the communication line if the communication line is crowded; determining whether or not the passed time of the connected state has reached a predetermined set-up time; and compulsorily interrupting the connected state of the communication line when the passed time of the connected state has reached the predetermined set-up time. Thus, even if a communication line is very crowded because a disaster has happened, it is sure to enable more people to make phone calls, without producing a situation in which the communication line is occupied by only few people.
