Description

Broadcasting system of switching system and its control method

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switching system having a broadcasting device, and more particularly, to a switching system and a method of controlling a remote broadcasting function, in which broadcasting contents are recorded in a VMS and then repeatedly reproduced. .

Typically, the switching system is equipped with a broadcast function to deliver a message by simultaneously calling a plurality of subscribers in the remote area over a dedicated line. These broadcasting functions are usually used to deliver broadcast contents to emergency workers in the immediate area or remote areas that need to share their use situations in case of emergency in fire, government offices and military units. However, in the conventional exchange system, the method of broadcasting to a remote site broadcasts a message to be delivered only once after calling a subscriber to be broadcasted, and if the broadcast content is very long, the receiver cannot recognize the content accurately by one listening and in an emergency situation. There was a problem that could not be coped.

Accordingly, an object of the present invention is to provide a switching system and a remote broadcasting function control method for solving the above problems.

It is another object of the present invention to provide a switching system and a remote broadcasting function control method capable of accurately recognizing broadcast contents by repeatedly recording the recorded broadcast contents and then reproducing the recorded broadcast contents when executing a broadcast from a remote location in the exchange system. Is in.

In order to achieve the above object, the present invention provides a switching system comprising a switching device having a broadcasting device and a VMS device connected to each other by a dedicated line and connected to a call switching port, wherein subscribers of any of the switching devices are connected to the subscriber. When the calling exchange calls the other party's incoming exchange through the leased line by calling a subscriber of the broadcasting device to another exchange through the leased line, when the terminating exchange receives the broadcasting device connection code in response to the call, the leased line and the A call path is formed between the subscriber port of the broadcasting device and the VMS device, and when the originating exchange transmits a voice message input from the originating subscriber to the destination exchange side through the leased line, the destination exchange is received from the originating exchange. To send a message to the broadcast device. By recording the broadcast at the same time as the VMS device, and when the broadcast is finished, the recorded broadcast message is repeatedly played.

2 is a control flow diagram for remote broadcasting according to an embodiment of the present invention

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a connection between an exchange system for performing broadcasting applied to an embodiment of the present invention. Exchange A 100 and Exchange B 200 are connected by telephone lines via dedicated lines. The switch A 100 and the switch B 200 have the same configuration and are provided with a broadcasting device. The exchanger A 100 and the exchanger B 200 each have the following configuration. The CPU 10 controls call switching, and controls various services and remote broadcasting functions. The trunk line connecting unit 12 forms a trunk line loop by scissing a dedicated line line under the control of the CPU 10, and interfaces signals that are incoming from the trunk line. The switching unit 14 switches various tone signal voice data under the control of the CPU 10. The ROM 16 is connected to the CPU 12 and stores a program for performing basic calls and various functions and a program for performing a broadcasting function. RAM 18 temporarily stores processing data during program execution. The broadcast device connection unit 20 connects the broadcast message received from the dedicated line connected to the switching unit 14 to the speaker 28 under the control of the CPU 10. VMS 24 stores various broadcast messages. The VMS connector 22 interfaces with the broadcast message to be stored in the VMS 24 when connected to the dedicated line through the switching unit 14 under the control of the CPU 10. The station connection unit 26 supplies the call current to the station subscriber and interfaces with the subscribers and the trunk line.

2 is a control flowchart for remote broadcasting according to an embodiment of the present invention.

1 to 2, the operation of the preferred embodiment of the present invention will be described in detail.

In FIG. 1, it is assumed that the switch A 100 is called a broadcast transmitting system, and the switch B 200 is called a broadcast receiving system. When the subscriber of the switch A 100 selects a leased line and calls a specific subscriber of the switch B 200 through the telephone station, the switch A 100 sends a broadcast device connection code to the bridge B 200. In step 101, the CPU 10 of the exchanger B 200 searches whether there is a dedicated line incoming from the CO line connection 12. If the dedicated line is received, the process proceeds to step 102 and the CPU 10 of the switch B 200 checks whether a broadcast device connection code is received from the leased line. When the broadcast device connection code is received, the CPU 10 of the switch B 200 controls the switching unit 14 to connect the dedicated line and the broadcast device connection unit 20 to form a call path in step 103. In operation 104, the CPU 10 of the switch B 200 controls the switching unit 14 to connect the leased line and the VMS connector 22 to form a communication path between the leased line and the VMS 24. Then, in step 105, the CPU 10 of the exchanger B 200 controls the VMS connector 22 to transmit a recording start message to the VMS 24. Then, the broadcast signal received through the spherical connector 12 of the switch B 200 is transmitted to the speaker 28 through the broadcast device connector and simultaneously recorded in the VMS 24 through the VMS connector 22. After the broadcast message is recorded, the subscriber of the switch A 100 hangs up and terminates the broadcast. In step 106, the CPU 10 of the switch B 200 checks whether the broadcast is terminated, and proceeds to step 107 when the broadcast ends. In step 107, the CPU 10 of the switch B 200 controls the switching unit 14 to disconnect the dedicated line and the broadcasting device connecting unit 20 to release the call path. In operation 108, the CPU 10 of the switch B 200 controls the switching unit 14 to release the communication path between the VMS 24 and the dedicated line. In step 109, the CPU 10 of the exchanger B 200 transmits a recording stop message to the VMS 24 through the VMS 22, and proceeds to step 110. In step 110, the CPU 10 of the switch B 200 controls the VMS connection device to play the broadcast message recorded in the VMS 24. At this time, in step 111, the CPU 10 of the switch B 200 controls the switching unit 24 to connect the VMS connector 22 and the broadcasting device connector 20 so that the broadcast message reproduced from the VMS 24 is repeatedly reproduced through the speaker 28. In this way, the person who receives the broadcast message presses the stop code using the subscriber telephone of the switch B200. In step 112, the CPU 10 of the exchanger B 200 searches whether a broadcast stop code is input, and when the broadcast stop code is input, proceeds to step 113. In step 113, the CPU 10 of the switch B 200 controls the switching unit 14 to release the call path between the VMS connector 22 and the broadcaster connector 20. In operation 114, the CPU 10 of the exchanger B 200 transmits a replay stop message to the VMS 24 through the VMS connector 22 to stop the play operation.

As described above, the present invention, when performing a broadcast in a remote location in the exchange system, and then recorded in the voice mailing system of the broadcast receiving device to reproduce the recorded broadcast content to accurately recognize the broadcast content, By accurately recognizing the announcement there is an advantage that can quickly take action according to the contents of the broadcast.
