Description

Broadcasting system of exchange system and control method thereof

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an exchange system having a broadcast apparatus, and more particularly, to an exchange system and a remote broadcast function control method in which broadcast contents are recorded in a VMS when a broadcast function is performed between exchange systems, .

BACKGROUND ART [0002] In general, an exchange system has a broadcasting function for simultaneously transmitting a message by calling a plurality of subscribers at a remote location via a dedicated line. These broadcast functions are used to deliver broadcast contents to emergency workers in remote areas where the emergency situation such as fire fighting, government offices, and military units should be shared in the nearby area or the usage situation. However, in the conventional switching system, when broadcasting is performed only once, a message to be transmitted is called only once after a subscriber to be broadcasted is called. Therefore, if the contents of the broadcast are very long, the receiver can not correctly recognize the contents by one- There was a problem that could not cope.

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

Another object of the present invention is to provide an exchange system and a remote broadcasting function control method which can record broadcast contents in a voice mailing system when a broadcast is executed in a remote place in a switching system and repeatedly reproduce the recorded broadcast contents to accurately recognize broadcast contents .

According to another aspect of the present invention, there is provided an exchange system comprising exchange units each having a broadcasting apparatus and a VMS apparatus connected to a call switching port by dedicated lines, Wherein the calling party of the broadcasting apparatus calls the other party's destination exchange through the dedicated line by calling the subscriber of the broadcasting apparatus through the dedicated line, and when the called exchange receives the broadcasting apparatus connection code in response to the call, The destination exchange establishes a call path between the subscriber port of the broadcasting apparatus and the VMS apparatus, and when the originating exchange transmits a voice message input from the calling subscriber to the destination switching center through the dedicated line, And transmits the message to the broadcasting apparatus And records the broadcast message to the VMS device. When the broadcast is finished, the broadcast message is repeatedly reproduced.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a diagram showing a connection configuration between switching systems for carrying out broadcasting,

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

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in detail with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram illustrating a connection system for exchanging broadcasting according to an embodiment of the present invention; FIG. The exchange A 100 and the exchange B 200 are connected via a telephone line to a private line. The exchanges A 100 and B 200 have the same configuration and include a broadcasting apparatus. The exchanges A 100 and B 200 each have the following configuration. The CPU 10 controls call switching and controls various services and remote broadcasting functions. The CO line connection unit 12 sees the exclusive line line under the control of the CPU 10 to form a CO line loop, and interfaces a signal to be incoming from the CO 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 a basic call 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 under the control of the CPU 10 so as to be output to the speaker 28. VMS 24 stores various broadcast messages. The VMS connection unit 22 interfaces the broadcasting message to be stored in the VMS 24 to be connected to the VMS 24 through the switching unit 14 under the control of the CPU 10. The extension connection unit 26 supplies the call current to the extension subscriber, and performs interfacing with the extension subscriber and the extension line.

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

The operation of the preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 to 2. FIG.

In FIG. 1, the description will be made on the assumption that the exchange A 100 is a broadcast origination system and the exchange B 200 is a broadcast reception system. When a subscriber of the exchange A 100 selects a dedicated line and calls a specific subscriber of the exchange B 200 through the telephone exchange, the exchange A 100 sends a broadcast device connection code to the exchanger B 200. At this time, in step 101, the CPU 10 of the exchange B 200 searches the trunk connection unit 12 for the presence of a leased line. If there is an incoming call on the leased line, the process goes to step 102 and the CPU 10 of the exchange B 200 checks whether a broadcast device connection code is received from the leased line. When the broadcasting apparatus connection code is received, the CPU 10 of the exchange B 200 controls the switching unit 14 to connect the leased line and the broadcasting apparatus connection unit 20 in step 103 to form a communication path. In step 104, the CPU 10 of the exchange B 200 controls the switching unit 14 to connect the leased line and the VMS connection unit 22 to form a communication path between the leased line and the VMS 24. In step 105, the CPU 10 of the exchange B 200 controls the VMS connection unit 22 to transmit a recording start message to the VMS 24. Then, the broadcast signal received through the wire connection unit 12 of the exchange B 200 is transmitted to the speaker 28 through the broadcast unit connection unit and is recorded to the VMS 24 through the VMS connection unit 22. When the subscriber of the exchange A 100 terminates the broadcast after recording the broadcast message, the CPU 10 of the exchange B 200 checks if the broadcast is terminated in step 106 and proceeds to step 107 when the broadcast is terminated. In step 107, the CPU 10 of the switching center B 200 controls the switching unit 14 to disconnect the leased line and the broadcasting apparatus connection unit 20, thereby releasing the communication path. In step 108, the CPU 10 of the switching center 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 exchange B 200 transmits a recording stop message to the VMS 24 via the VMS 22, and proceeds to step 110. [ In step 110, the CPU 10 of the exchange B 200 controls the VMS connection device to reproduce the broadcast message recorded on the VMS 24. In operation 111, the CPU 10 of the switching center B 200 controls the switching unit 24 to connect the VMS connection unit 22 and the broadcasting apparatus connection unit 20 so that the broadcasting message reproduced from the VMS 24 is repeatedly reproduced through the speaker 28 frame. The person who receives the broadcast message in this way presses the broadcast stop code using the subscriber's telephone of the exchange B 200. In step 112, the CPU 10 of the exchange B 200 searches for a broadcast stop code, and if the broadcast stop code is input, the process proceeds to step 113. In step 113, the CPU 10 of the switching center B 200 controls the switching unit 14 to release the communication path between the VMS connection unit 22 and the broadcasting apparatus connection unit 20. In step 114, the CPU 10 of the exchange B 200 transmits the repeat play stop message to the VMS 24 through the VMS connection unit 22 to stop the play operation.

As described above, according to the present invention, when a broadcast is executed in a remote place in an exchange system, it is recorded in a voice mailing system of a broadcast receiving apparatus, and the recorded broadcast contents are repeatedly reproduced to accurately recognize broadcast contents. There is an advantage that it is possible to promptly recognize the announcement and take measures in accordance with the broadcast contents.
