The display unit 10, the selection switch unit 11 for controlling the selection of the talk group, the terminal connection, and the like, and the switch selection state of the selection switch unit 11; And a control unit 12 for controlling to display the received selection state on the connection display unit 10.

Referring to the operation of the group call system of the present invention configured as described above are as follows.

First, the circuit configuration diagram of the present invention of FIG. 1 will be described with reference to the flowchart of main device control of FIG. 2 as follows.

In step 201, the device is initialized by the central controller 4, and in step 202, the communication unit 1 receives the information of each terminal under the control of the central controller 4.

That is, information is received from each terminal by using a communication line connected to the connection device 3, and the received information is stored in the main memory section 5.

In the next step 203, if the member ID is input, the central controller 4 verifies the reliability of the member ID to confirm that the call is allowed, selects the call path by controlling the voice switching unit 2 (step 214) The controlled state is transmitted to the terminal through the access device 3 and ends (steps 215 and 216).

On the other hand, if the member ID is not entered in step 203, the process proceeds to the group selection step 204 to designate a new group (step 205) and to select a call path or to determine whether the group is currently in use ( Proceed to step 206, or to step 207 of ungrouping.

At this time, if it is not the group currently being used in the step 206 of determining the group currently being used, the corresponding memory is stored in the main memory unit 5 through the step 208 of adding the new group, and the currency path is selected. If the group is currently in use, the process proceeds to step 209 to determine whether the group currently being used is locked, i.

As a result of the determination in step 209, if the group currently being used is in the locked state, the process proceeds to step 210 where group designation is impossible and the voice switching unit 2 is controlled.

On the other hand, if the group is released in step 204, the process proceeds to step 211 through step 207 to escape the call group and controls the voice switching unit 2, if not the group is unlocked? (Step 212), if it is a group lock, lock the group currently being used (step 213), and control the voice switching unit 2, and if it is not a group lock, transmit the controlled state and end.

3 is a flowchart illustrating a control procedure of a terminal. Referring to FIG. 3, the operation of the terminal in the present invention will be described below.

First, in step 301, when power is supplied and data reception is performed, in step 302, the control unit 12 performs self-diagnosis of each circuit part, and proceeds to step 303, and the result is displayed in the connection display unit 10. In addition to the above, initialization of each part of the circuit is performed.

In step 304, the control unit 12 displays the connection information on the connection display unit 10. For example, the control unit 12 displays the call group including the terminal and the number of terminals included in the call group, and then calls. When setting a group, the number of the terminal to be set is displayed.

In the next step 305, the select key of the selector switch unit 11 is checked. The selector switch 11 includes an up switch (Up), a down switch (Down), a set switch (Set), a lock switch (Lock), A reset switch and a call switch Call are provided.

Up switch selects the previous talkgroup, Down switch selects the subsequent talkgroup, Set switch selects the talkgroup, and Lock locks itself. It is a function to prevent another terminal from being connected to the included call group, and a call switch (Call) is a function of calling the manager terminal (6).

The functions of the switches are performed by the control unit 12 recognizing the selection and manipulation of the selection switch unit 11.

That is, the control unit 12 searches for the function of the selection switch unit 11, and in the case of a set switch, proceeds to step 306 to perform group selection, and in the case of a lock switch, step In step 307, the group lock is controlled, and in the case of a reset switch, the control proceeds to step 308 to control the ungrouping.

In this way, it is determined whether or not normal selection is made in step 309. If normal selection is not made, the process proceeds to step 305 again, and performs the selection key check again, and if normal selection is made, the communication unit 9 Control to transmit data to the host device and then end.

In this manner, a call is made between the main device and the terminal. At this time, the headset listens to the audio signal of the other party using a headset and a microphone and transmits its own voice signal to the other party.

That is, in the state where the connection unit 7 is connected through the communication line with the main unit, the call and the sign language are divided and synthesized (Speed Network), and the mixer unit 8 separates the input voice signal from the talk group formed by the main unit. (Song and Sign Language) combines the contents of the call with the output of the sound card of the terminal and connects them to the headset circuit of the Head Set.

As described above, according to the group call system of the present invention, it is possible to make a call by giving a plurality of screening and call permission to each other in its own system, and also, by combining music or other sounds in each system at the time of the call, the call is possible. It can synthesize network game sound and perform sound simultaneously with voice call.

In addition, the group call system of the present invention can install the device of the present invention in individual places, perform a call by group through the main device, and connect the speaker line and the microphone line to the main device using the sound card of the computer terminal. You can connect and make calls by group.

In addition, the group call system of the present invention provides a group call system that can install a separate device device inside the computer and perform a group call through the main device.

Therefore, in the present invention, the call can be set up by individuals or groups, and in addition to voice, music and game sounds can be selected and listened to, so that multiple calls in a network game room (Internet game room), departments within a company building, or It is possible to provide a multi-call system capable of calling and conferencing by desired groups.
