Abstract

PURPOSE:To flexibly transmit messages by changing the kinds of messages to be transmitted to a terminal at a call incoming destination according to time reading the messages from the terminal at the call incoming destination. CONSTITUTION:In a private exchange 2, the message to be transmitted to a terminal 1 at the call incoming destination is changed according to the time reading the message from the terminal 1 at the call incoming destination. Namely, when reading the message until time t1, a message M1 is transmitted to a message reader, when reading the message from the time t1 to time t2, a message M2, is transmitted to the message reader and when reading the message from the time t2 to time t3, a message M3 is transmitted to the message reader. Thus, the message is transmitted to the terminal at the call incoming destination exactly corresponding to the time.

Description

[Detailed Description of the Invention] [Summary] Regarding a multiple message registration system in a private branch exchange, the object of the present invention is to enable a message waiting registrant to send different messages to a registered person depending on the reading time of the message reader. , a private branch exchange having a function of leaving a message on the called terminal when the called party is not present, comprising time/message storage means for storing in advance a plurality of times and a plurality of messages corresponding to each of the plurality of times, The message sent to the destination terminal is configured to be changed depending on the time at which the message is read from the destination terminal.

[Industrial application field]

The present invention relates to a multiple message registration system in a private branch exchange that enables more flexible message transmission by changing the type of message sent to a destination terminal depending on the time at which the message is read from the destination terminal.

[Conventional technology]

In the conventional technology, the same message is always sent to the destination terminal regardless of when the destination terminal responds.

[Problem to be solved by the invention]

According to Kamikita's conventional technology, the message may be meaningless depending on the reading time from the destination terminal. For example, a message requesting a call back to the office becomes meaningless after the message registrant leaves the office.

An object of the present invention is to enable a message waiting registrant to send different messages to registered users depending on the reading time of the message reader.

[Means to solve the problem]

FIG. 1 is a diagram explaining the principle of the present invention. In the figure, a private branch exchange 2 that has a function of leaving a message on the destination terminal 1 when the destination is not present has a time/message storage that stores in advance a plurality of times and a plurality of messages corresponding to each of the plurality of times. A means 3 is provided to change the message sent to the destination terminal 1 depending on the time at which the message is read from the destination terminal 1.

[Effect]

If the message is read by time t1, message M is sent to the message reader, and if the message is read from time t1 to t2, message M2 is sent to the message reader.
is sent to the message reader, and from time t2 to t3
If a message is to be read, message M3 is sent to the message reader. As a result, a timely and accurate message is sent to the destination terminal.

〔Example〕

FIG. 2 is a block diagram illustrating a multiple message registration system in a private branch exchange according to an embodiment of the present invention. In the figure, a private branch exchange 21 includes telephone terminals 22 and 2.
3 is connected. The private branch exchange 21 includes a central processing unit (CC) 210, a main memory (MEM) 211 that stores a table that associates time and messages, a clock device (CLK) 212, and a communication path 213 between terminals. An input buffer memory 214 temporarily stores human input data for each terminal, an output buffer memory 215 temporarily stores output data output for each terminal, and sends data from the terminal 22 to the input buffer memory 214. , a local processor (LPR) 21 that controls the protocol for sending the contents of the output buffer memory 215 to the terminal 22.
6 and manually buffer memo data from terminal 23! J
214 and the contents of the output buffer memory 215 to the terminal 23.

The terminal 22 has a display 221 that displays messages, and an LE that displays messages from other terminals.
It is equipped with a D lamp 222 and a function button 223 used when sending a message to another terminal or when displaying a message from another terminal on the display 221.

Similarly, the terminal 23 has a display 231 and an LED lamp 232.
and a function button 233.

FIG. 3 is a diagram showing an example of the contents of the main memory device (MEM) 211 shown in FIG. As shown in the figure, the terminal number of the message waiting registration destination, the time, and the message and the terminal number of the message waiting registration destination are stored in correspondence with the time.

For example, the registration source end bundle of terminal number 200 is terminal number 201.
For the terminal, a message is registered to call back to the office by 7:00, and a message is registered to call back to home from 7:00 to 8:10.

FIG. 4 is a flowchart illustrating the operation of the central processing unit (CC) 210 when the sending terminal (A) 22 registers a message. In the same figure, in step 41, check whether there is input information from terminal A with manual buffer memo')
214, and if yes, inquires in step 42 whether the message waiting button 223 is pressed. If it is pressed, in step 43, the telephone number of the destination terminal, the message, and how long the message is valid are shown. Store the time in the main memory (MEM) 21
1, and in step 44 the main memory device (MEM) 21
Add to message waiting table in 1.

Next, in step 45, the message waiting lamp 232 of the destination terminal (B) 23 is turned on. If the message waiting button 223 is not pressed, a function different from inputting a message is processed.

FIG. 5 is a flowchart illustrating the operation of the central processing unit (CC) 210 when displaying an incoming message on the receiving terminal. In the figure, step 51
Inquires of the input buffer memory 214 whether there is input information from the terminal, and if so, in step 52 inquires of the input buffer memory 214 as to whether the message waiting button 233 of the receiving terminal (B) 23 is pressed. If pressed, the message waiting table in the main memory (MEI 211) is searched in step 53 using the called party's telephone number and the current time based on the clock device 212 as keys.Then, in step 54, the message waiting table in the main memory (MEI 211) is searched. The corresponding message is sent to the display 23 of the terminal (B) 23 via the output buffer 215.
Display it on 1. If the message waiting button is not pressed in step 52, a function other than message display is performed.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, a message waiting registrant can send different messages to a registered person depending on the reading time of the message reader.
