Referring to FIG. 5, the mutual simultaneous call apparatus of the present invention connects a call in step 500. When receiving the request signal, the flow proceeds to step 502 to confirm the received number, and proceeds to step 504 to confirm the stored call connection information to determine whether the receiving terminal is attempting to call in the mutual simultaneous mode.

In step 504, if the receiving terminal is trying to make a call in the mutual call mode, the mutual call device proceeds to step 506 to compare the call connection request signal with the stored call connection information and connect the call. It is checked whether the sender terminal and the receiver terminal of the request signal are in mutual call simultaneously with each other requesting connection to the other party. If the check result of step 506 is not the same time, the process proceeds to step 520 and outputs a call unavailable signal to the transmitting terminal of the call connection request signal.

In step 506, if the call is in the same call, the device for performing the simultaneous call proceeds to step 508 and selects a terminal to terminate call connection using a predetermined selection method. The predetermined selection method includes the caller or the caller having a larger telephone number or a smaller telephone number by comparing the sizes of all or a predetermined number of the calling party and the receiving party telephone number of the call connection request signal. A method of selecting a receiving terminal.

In step 508, if the terminal to be terminated is selected, the mutual simultaneous call apparatus proceeds to step 510 and includes the transmitting side and the receiving side of the call connection request signal, respectively, in different mutual simultaneous apparatuses, Check whether the terminal is a terminal included in the mutual call apparatus managed by the mutual call apparatus. If the check result of step 510 includes the transmitting side and the receiving side of the call connection request signal in different mutual simultaneous calling apparatuses, and includes a terminal to be terminated, then control for subsequent mutual calling connection is terminated. It is performed in a terminal that does not include a terminal to perform.

As a result of the checking in step 510, if the mutual call device includes both the transmitting side and the receiving side of the call connection request signal or does not include a terminal to be canceled, the mutual calling device proceeds to step 512. The mutual simultaneous call device including the terminal to be terminated is requested to terminate the connection with the selected terminal and output a connection waiting signal, and the process proceeds to step 522 to connect the call.

If the receiving terminal is not attempting to make a call in the mutual simultaneous call mode as a result of step 504, the mutual calling device proceeds to step 514 to determine whether the receiving special terminal is in a call. Proceed to step 522 to establish a call.

If the receiving terminal is in a call as a result of the checking in step 514, the mutual calling apparatus proceeds to step 516 to determine whether the receiving terminal is also in a simultaneous call attempting to connect to the transmitting terminal. If the check result of step 516 is not the same as the mutual call, the flow proceeds to step 520 and outputs a call unavailable signal to the transmitting terminal of the call connection request signal.

In step 516, if the call is being performed at the same time, the mutual call device proceeds to step 518 to terminate the connection with the receiver terminal and outputs the connection wait signal to the receiver terminal. Proceed with the call connection by sending a connection command to the mutual simultaneous call device that sent the call connection request signal.
