Abstract

PURPOSE:To output alarm information at the time of emergency generated by an operation of an external connecting device of a computer, as an alarm to a radio telephone set. CONSTITUTION:This exchange is provided with connecting devices 6-9 for containing radio telephone sets 10-15 of a private branch HCA, line controllers 4, 5 for controlling the connecting devices 6-9, a central controller 2 for controlling the radio telephone sets 10-15 of the private branch MCA through the line controllers 4, 5 and the connecting devices, and an interface controller 3 which is connected to the central controller 2 and has an interface bus to an external computer 17. The central controller 2 discriminates position registering information of the radio telephone sets 6-9 of the private branch MCA, and informs alarm information received from the external computer 17 through the interface bus 16 to the radio telephone sets 10-15 of the private branch MCA, which are positioned and registered.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a private branch electronic exchange, and more particularly to a private branch electronic exchange that accommodates a wireless telephone of a private branch MCA.

[0002]

2. Description of the Related Art Conventional electronic exchanges for premises have been unable to notify alarm information to an MCA radio telephone for premises from an external connection device such as a computer.

[0003]

In this conventional private branch exchange, since it is not possible to notify the alarm information from an external device such as a computer to the radio telephone of the private branch MCA, it can be carried during an emergency such as a disaster. There was a problem that it was not possible to report the disaster occurrence through the wireless telephone of the on-premises MCA.

[0004]

A private branch electronic exchange according to the present invention includes a connection device for wirelessly transmitting and receiving signals to and from a wireless telephone of a private MCA, a line control device for controlling this connection device, and a line control device for this line control device. In a private electronic exchange including a central control unit for controlling the wireless telephone via a device and an interface control unit connected to the central control unit by an interface bus with an external computer, the central control unit is the wireless unit. The location registration information of the telephone is identified, and the emergency alert information received from the external computer is transmitted to the wireless telephone.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of an embodiment of the present invention.

In this embodiment, a wireless telephone 1 for a local MCA
Connection devices 6-9 for accommodating 0-15 and connection devices 6-9
Connected to the central control unit 2 and the central control unit 2 for controlling the radio telephones 10 to 15 of the MCA for premises via the line control units 4 and 5 and the connection units. An interface control device 3 having an interface bus with an external computer 17 is provided. The central control device 2 identifies the position registration information of the wireless telephones 6 to 9 of the local MCA, and the external computer 17 via the interface bus 16. The wireless telephones 10-15 of the indoor MCA for which the alarm information received from the location is registered.
It is configured to notify.

FIG. 2 is a format diagram showing the alarm information of this embodiment. The message format includes a message identifier 21 of the message itself, a message type 22 that represents the meaning of the message such as alarm information, a first information field 23 that can be added according to the meaning of the message type 22, and a second Information Field 24
And a third information field 25.

At the same time as the emergence of an emergency, the operator receives the terminal device 20.
Is operated to instruct the external computer 17 to send an alarm message. In addition, the warning message is a specific premises MC
In the case of a command to the wireless telephone of A or the wireless telephone of MCA for the premises within the radio range of the specific connection device, the location registration information of the wireless telephone of the MCA for premises in the database 18 is searched through the monitor device 19 and the destination is designated. can do.

When the external computer 17 receives the warning message sending command, it edits the warning message according to the command contents and sends the warning message to the interface control device 3 via the interface bus 16.

The contents of the message format will be described with reference to FIG. 2. The message identifier 21 is a (FF) 16 code indicating the start of the message, and the message type 22 is an alarm command (AA) ASC2.
(AC) ASC2 if the alarm is for all wireless telephones that are filled with the ASC2 code (AA) ASC2 is an alarm for a wireless telephone within the transmission range of a specific connection device (AC) ASC
2 is inserted in the message type 22. If the message type 22 is (AA) ASC2, the first information field 23 is blank, the extension number of the wireless telephone is (AB) ASC2, and the device number of the connected device is (AC) ASC2. Is inserted.

In the second information field 24, a warning type such as lightning strike / earthquake is inserted by a predetermined ASC2 code, and in the third information field 25, a warning sound or a warning light for the wireless telephone is given. Alternatively, the terminal control information such as the warning character display information is also inserted in the predetermined ASC2 code.

When the central control unit 2 receives the alarm message transferred from the interface control unit 3 via the interface bus 16, the central control unit 2 analyzes the content of the message, and the message type 22 and the first information fill rule 23
Identifies the premises MCA radiotelephone to be the alarm target. Then, the second information is identified from the contents of the field 24 and the third information field 25, the alarm type and the terminal control information are identified, and connection is made via the line control devices 4 to 5. Controls the devices 6 to 9 and performs terminal notification control such as warning sound, warning light, or warning character display on the target wireless telephones 10 to 15 to call the user's attention, and gives details of disasters and warnings and instructions on blame. To provide the information.

[0013]

As described above, according to the present invention, a central control unit receives alarm information from an externally connected device such as a computer and informs the alarm information to a wireless telephone of an MCA on the premises.・ When a disaster such as a tsunami or an avalanche occurs, it has the effect of being able to report the occurrence of a disaster through a wireless MCA on-premises mobile phone.
