Abstract

PURPOSE:To efficiently accumulate and erase messages by erasing the accumulated messages when registered users complete the extraction of all the messages. CONSTITUTION:A control part 12 accumulates the messages transmitted for an electronic notice board 11 from terminals 1-9. At that time, the control part 12 correspondingly stores the reception destinations of the messages transmitted from the terminals 1-9 and the messages in a control table 23. Next, the control part 12 judges whether the messages are alloted to all receivers registered in the control table 23. When allocation terminates, the messages are erased. When allocation is judged not to be terminated, the messages are alloted to the terminals receiving the request of extraction.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a message communication system, and particularly relates to a message storage and exchange service [Prior Art] Conventionally, in a message communication system, messages are stored on electronic bulletin boards. The deleted messages are deleted when a specified time has elapsed, or when a message deletion request command is issued from the terminal to the center or by the center.

[Problem that the invention is trying to solve] However,
In the conventional example described above, accumulated messages are not deleted until a specified time is reached or a message deletion request command is issued, so all users who actually need the messages must delete the messages. Even after the data is withdrawn, it remains accumulated until one of the above operations is performed, resulting in wasted memory use.In addition, the data is actually stored because the specified time is reached or the deletion request command is issued. In some cases, the message was deleted before the user who needed it could retrieve it.

[Means and effects for solving the problem] According to the present invention, by registering users who need messages stored on an electronic bulletin board, when all those users have retrieved the messages, , to erase messages.

〔Example〕

FIG. 1 is a schematic configuration diagram of a message communication system in which nine terminals are connected. In the figure, 1 to 9 are terminal devices that send and receive messages, and 10 is a center device of the message communication system that has a message storage and exchange function. 11 is a message storage area (electronic bulletin board), 1
Reference numeral 2 denotes a control unit that controls the entire electronic bulletin board and message storage/exchange function.

The control unit 12 includes a FLOM that stores the processing programs shown in FIGS. 5 and 6, and a RAM that is used as a working area when executing each program. 13 to 21 are terminal devices 1 to 9 and center device 10
A communication line that connects the Internet and serves as an exchange network for sending and receiving messages.

FIG. 2 is a schematic diagram of the electronic bulletin board.

22 is an accumulated message; 23 is a control unit 12;
is a management table used when storing, distributing, and deleting messages. First, in this embodiment, a recipient name table 24 is provided in the management table 23. It is now assumed that terminals 1 to 6 are registered in the recipient name table. This registration is for terminals 1 to 9.
When a message is stored on this electronic bulletin board from any of the above, it is input from the terminal. A terminal registered as a receiving terminal is configured to set a flag in the management table.

In this case, the accumulated messages and the receiving terminals are associated with each other by the message numbers shown at 30. Accumulated messages can be retrieved from any of the terminals 1 to 9, but all terminals registered in the recipient name table, except for the terminal that stored the message, cannot withdraw the message. Once completed, the accumulated messages will be deleted. Figure 5 shows the control unit 12 at this time.
3 is a flowchart showing the operation of FIG. First, the Sl stores messages sent from terminals for the electronic bulletin board. At this time, the control unit 12 associates the recipient of the message sent from the terminal with the message and stores it in the management table 23.

In S2, it is determined whether the message has been delivered to all recipients registered in the management table 23, and if the delivery has been completed, the message is deleted in S5.

If it is determined in S2 that the distribution is not completed, the process proceeds to S3 and S4, and the message is distributed to the terminal that received the withdrawal request.

[Other Examples]

FIG. 4 is a diagram in which the management table 23 has been changed. In this case, recipient names are divided into groups and registered. After the message is accumulated on the electronic bulletin board, the message is deleted when at least one terminal in each group completes withdrawal of the message.

For example, if the same message is registered in message No. 3 and Q3, if the registered message is retrieved from recipient name 2, recipient name 6, and recipient name 7, the message will be deleted. Figure 6 shows the control section 1 at that time.
2 is a flowchart showing control of step 2. Steps that perform the same processing as in FIG. 5 are given the same step numbers, and their explanations will be omitted.

In 52-1, it is determined whether distribution has been performed to all groups registered in the management table 23. If yes, proceed to S5; if no, proceed to 83.84. Management in this case Registration in Table 11 is done by inputting the recipient group name from the terminal that stores the messages, as in the previous embodiment.Recipient names and recipient group names can also be registered by sending messages at the center. ◇ [Effects of the invention] As explained above, the users who actually need the messages accumulated on the electronic bulletin board are registered, and those users By deleting the accumulated messages when the withdrawal of messages is completed, the messages can be withdrawn without fail if a registered user requests withdrawal of the messages. Additionally, there is no need to waste memory, where messages remain stored even after all registered users have withdrawn their messages, and messages can be stored and deleted more efficiently. be.
