DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an audible message control system for an exchange, and more particularly to a control system for determining an audible message of a tone or an announcement in accordance with a call state in a program storage type exchange and outputting it to a terminal or a trunk. .

[0002]

2. Description of the Related Art Conventionally, this type of audible message control system is such that a call control unit 360 and a protocol control unit 310 transmit and receive call control messages 510 and 520 via a communication bus 300 as shown in FIG. To determine the audible message to be sent out,
Audible messages such as tones and announcements are transmitted to the terminal and the trunk by transmitting the switch control signals 530 and 540 to the terminal and the trunk.

[0003]

As described above, in the conventional audible message control system of the exchange, operations for selecting and outputting an audible message are distributed to the call control unit 360 and the protocol control unit 310. Call control unit 360
Alternatively, the audible message control other than the original operation of the protocol control unit 310 must be performed, and the audible message function is distributed between the call control unit 360 and the protocol control unit 310. And an audible message control state mismatch may occur. Further, when the switch control method in the switch control unit 320 is changed, there is a problem that both the call control unit 360 and the protocol control unit 310 need to be changed.

Accordingly, it is an object of the present invention to provide an audible message of an exchange which solves the above-mentioned problem by monitoring a call control message exchanged between a call control unit and a protocol control unit and selecting and transmitting an audible message. It is to provide a control method.

SUMMARY OF THE INVENTION An audible message control system for a switch according to the present invention comprises a tone generator for a terminal and a trunk.
Audible sound output that outputs audible messages for announcements and announcements
A source, the audible sound resource, the terminal and the
Connection and disconnection of the switch for connection to the
And Gosuru switch controller, a protocol control unit to create a first call control message to process each protocol by events for each color of the terminal and the trunk, communications
Connected to the protocol control unit via a bus, receives the first call control message output from the protocol control unit, performs a call control operation, creates a second call control message, and sends the second call control message to the protocol control unit. a call control unit for outputting a bus probe unit for monitoring said first and second call control message is output on the communication bus, wherein the first and second call control messages monitored by the bus probe portion To the terminal and the trunk based on
It should tone or determine an announcement, the switch
Controlling the control section to determine the tone or announcement
The audible sound resource corresponding to the
An audible message control unit for performing switch connection control between ranks .

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. The switch 120 of the program storage type exchange is
The terminal 100 and the trunk 13 through the subscriber circuit 110
0 and an audible sound resource 200 for outputting an audible sound such as a tone or an announcement. The switch control section 220 controls connection / disconnection between these circuits. Terminal 10 through subscriber circuit 110
A terminal protocol control unit 210 that processes a protocol by an event from 0 and generates a call control message CC1
And a trunk protocol control unit 230 that processes a protocol based on an event from the trunk 130 to generate a call control message CC2, and receives call control messages CC1 and CC2 from the terminal protocol control unit 210 and the trunk protocol control unit 230 to perform call control. A call control unit 260 that operates and generates a call control message CC3 is mutually connected by a communication bus 300, and a bus probe unit 240
Are the respective call control messages CC1, CC on the communication bus 300.
2, monitor CC3 and output a monitoring message MM. The audible message control unit 250 receives the monitoring message MM, determines a tone or an announcement, outputs a switch control signal SC, and outputs the switch control signal SC.
Control 0.

[0008] This exchange comprises a call controller 260, a terminal protocol controller 210 and a trunk protocol controller 230.
Call control messages CC1, C1 exchanged between
The bus probe unit 240 monitors C2 and CC3, and the audible message control unit 250 monitors the monitoring message MM that is the monitored call control message.
The audible message to be output is determined based on the call control unit SC and the terminal protocol control unit 2 by controlling the connection of the switch 120 by the switch control signal SC to the switch control unit 220.
10 and the trunk protocol unit 230 do not participate in the audible message output at all.
It is possible to control the output of audible messages to 30.

[0009]

As described above, in the audible message control system of the exchange according to the present invention, the audible message control function is not distributed between the call control unit and the protocol control unit. Since only the original operation need be performed without performing the processing for selection and output of, the load on each control unit is reduced, and there is no possibility that the audible message control state mismatch occurs. When the switch control method or the like is changed, there is an advantage that only the audible message control unit need be changed without changing the call control unit and the protocol control unit.
