Since this is an open matter, no full text was included.

1 is a hardware configuration diagram to which the present invention is applied, FIG. 2 is a flowchart showing the overall process of performing the present invention, and FIG. 3 is a flowchart showing a process of constructing a call path between calling and receiving subscribers for a general call.

Claims (7)

A network subsystem (INS) 500 incorporating a space switch (SSW); An electric tester which is connected to the network subsystem 500 and has a call route system composed of a plurality of subscriber exchange subsystems (ASS) 100 to 400 with a built-in time switch (TSW) and controls a special call route. For a general call, a call path between an originating subscriber (a specially provided subscriber, referred to as a first subscriber) and a called party (the first subscriber and the first subscriber, the second subscriber). A first step of configuring and connecting; A second step of additionally constructing a special call channel to the calling subscriber and the third subscriber while maintaining the existing calling / receiving call path when the calling subscriber requests it; A third step of cutting the general call channel and connecting the special call channel so that the calling subscriber can talk to the third subscriber; A third step of releasing the general call channel when the call of the called party included in the special call ends; A fifth step of switching the call path between the calling subscriber and the third subscriber to the general call at the end of the special call; The method of controlling a call of a special call comprising the sixth step of releasing the call to the general call when the call of the calling subscriber switched from the special call to the general call ends. 2. The method of claim 1, wherein the first step comprises: a first step of investigating whether the call is released from the calling party; And a third step of storing the call path information in the general call information location. The method of claim 1, wherein the second step comprises: a first step of investigating whether a general call is established; A second step of additionally constructing a special call channel to the calling subscriber and the third subscriber while maintaining the existing call route between the called party and the called party; And a third step of storing the call path information in the special call information position. The method of claim 1, wherein the third step comprises: a first step of investigating whether a special call is made; Cutting the general call channel; Special call channel control method comprising the third step of connecting the special call channel. The method of claim 1, wherein the fourth step comprises: a first step of investigating whether a general call is established; A second step of releasing the general call channel; Special call channel control method, characterized in that the third step of maintaining the connection state. The method of claim 1, wherein the fifth step comprises: a first step of investigating whether a special call is made; A second step of storing the information of the special call as the information location in the general call; Special call call control method, characterized in that the third step of maintaining the connection state in the general call call. The method of claim 1, wherein the sixth step comprises: a first step of investigating whether a general call is connected; Special call channel control method comprising the step of releasing the general call channel. ※ Note: The disclosure is based on the initial application.
