Abstract

PURPOSE:To inform a remote party of the arrival of a message even in the case the message is displayed to the remote party by transmitting it through an ISDN network by transmitting the message by adding a feature activation information element to it at the time of the transmission of the message. CONSTITUTION:A repeating system is constituted of a sound accumulation device 10, an accumulation device processing circuit 11, a time division switch 12, a switch processing circuit 13, an interface trunk circuit 14, a D channel control circuit 15, the ISDN network 17, and a remote party side terminal 19. Here, when the message is sent to the remote party, a telephone number for displaying the arrival of the message is read out of storage contents, and the feature activation information element and an arraival number information element are sent to the ISDN network 17 based on this telephone number. Then, when this feature indication information element arrives, a terminal telephone set 19 lights a lamp, and reports the arrival of the message. Thus, even if a terminating side is not careful, it becomes aware that the message has arrived.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention provides a message arrival display that displays message arrival to a telephone with a visual display function connected via a private branch exchange having an I interface specified in the CCITTT Recommendation. This relates to display methods.

[Conventional technology] In recent years, SDN services have been launched, and it has become possible to receive various services that were not available in the past. There are message services etc. that can be displayed. By using this method, the receiving party does not have to respond each time information arrives, and can simply view the message that has arrived when necessary, which is a very convenient function for busy people.

[Problem to be solved by the invention] However, even if a message arrives, unless the other party sees it, the message cannot be communicated. Conventionally, messages are simply displayed on a display. The problem was that unless the receiving party was paying attention, they would not know that the message had arrived.

[Means for Solving the Problems] In order to solve these problems, this invention
The arrival of a message is displayed by sending a signal to the ISDN network to control a lamp function that is inherent in the network and whose use can be freely determined.

C Effect] When a message to be sent arrives at the local exchange, a message arrival display control telephone number corresponding to the subscriber number of the other party is determined, and a message arrival display control signal is sent to the ISOX network using that number. (5) In the 5SDN network, the signals are used to control existing functions and display a message to the subscriber on the other side, as well as a lamp display.

[Embodiment] FIG. 1 is a relay system diagram showing an embodiment of the present invention.
In the figure, the audio storage device lO1 storage device processing circuit 11-
The time division switch 12, switch processing circuit 13, -next group interface trunk circuit 14, and D channel control circuit 15 are functions housed in the private branch exchange. The central processing unit 11 of the audio storage bag WlO is capable of communicating with the central processing unit 113 of the time division switch 12, and the -next group inter-7 eighth trunk circuit 14 is configured to communicate with the D channel control circuit 15 having the LAP-D procedure. Layer 3 call control information is exchanged with the switch processing circuit 13 via the switch processing circuit 13.

Further, the other party's terminal 19 is accommodated in the ISDN 11117 via the 2B+D basic interface 18.

In the device configured as described above, when a message arrives from the private branch exchange side to subscriber A of the other party's terminal 19, the message arrival control telephone number registered in advance in the voice storage device IO is determined based on the information. It is determined from subscriber A's subscriber number.

FIG. 2 shows the switch processing circuit 1 from the storage device processing circuit 11.
This is a message arrival display control signal sent to 22. , and sends a message arrival display control signal to the switch processing circuit 13.

As a result, the switch processing circuit 13 expands the telephone number 22 of the received signal and recognizes that the destination is the route of the primary group interface trunk circuit 14.

FIG. 3 shows a call setup (SETLIP) message sent from the switch processing circuit 13 to the ISDNll17.

The switch processing circuit 13 adds feature activation information element 33 to the call setup (5ETUP) message that identifies a temporary connection that does not use the B channel.
34.35 and called party number elements 36.37 and 38.39. A lamp control code defined in advance between ISDN networks is set in the feature activation information element 35. Further, the number digit 39 is set with the telephone number 22 for displaying message arrival converted into [^5 characters. This call setup (SETUP) message is sent to ISDNlfl1 via the D channel control circuit 15 and the primary group interface trunk circuit 14.
Sent on 7th.

FIG. 4 shows a call setup (SETLIP) message sent from the ISDN network 17 to the terminal 19. This function is originally provided in the ISDN network, but in this application, this function is used to control the lamp of the other party's telephone to which the message is sent. It is used for. A signal for performing this control is sent out as shown in FIG. rsDNill17 is the third
When the call (SETUP) setting message shown in the figure is received, the feature activation identification number 4 is sent to the terminal 19.
A call setting message including a lamp control code in 5 and a feature indication information element in which status display 46 is set to start is sent. Based on the feature indication information element, the terminal 19 can turn on the lamp attached to the terminal to notify subscriber A that the message has arrived.

[Effects of the Invention] As explained above, in this invention, a feature activation information element is added and transmitted when a message is transmitted, so that when a message is transmitted via an ISDN network and displayed to the other party, However, it has the effect of notifying the other party of the arrival of the message.

Claims (1)

[Scope of Claims] Connected via a private branch exchange having an I interface that sends a feature indication information element to a terminal telephone when a feature activation information element and a called number information element arrive as specified by the CCITT recommendation. In a message arrival display method for displaying the arrival of a message on a telephone with a visual display function, there is provided a means for storing a telephone number for displaying message arrival corresponding to the subscriber number of the other party, and a message from the stored contents when a message is to be sent to the other party. By being equipped with means for reading a telephone number for arrival indication, and means for transmitting a feature activation information element and a called party number information element to the ISDN network based on the telephone number, the terminal telephone can receive the feature information supplied from the ISDN network. A message arrival display method is characterized in that when a message information element arrives, a lamp is lit to notify the arrival of a message.
