Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a message communication system, and more particularly to a message communication system having a mailbox for storing a message in a system.

2. Description of the Related Art Generally, in a message communication system including a mailbox for storing a message in a system, a message transmitted by a sender is transferred based on address information set in the message. Stored in the recipient's mailbox.

As this message communication system, for example, there is a message communication system disclosed in Japanese Patent Application No. 1-328014 filed by the present applicant.

The mailbox of the message communication system is provided so as to correspond to each user (user correspondence), and the message is composed of message control information such as a sender name and a subject and a message body. .

When a user makes a mailbox search request to the system, the system transfers a list of messages stored in the user's mailbox to the user. If a search condition such as a sender name is specified in this search request, the system transfers a message list to the user only for messages satisfying the search condition among the messages in the mailbox. The transfer of the message list transfers a message identifier (a unique value is assigned to each message) and message control information for each message.

When the user selects a desired message from the transmitted sender name or the like in the transferred message list and makes a reading request to the system, the system transfers the corresponding message body to the user. When the user makes a request to delete a message that is no longer needed in the system, the system deletes the message from the mailbox.

[Problem to be Solved by the Invention] As described above, the conventional message communication system
When a message arrives at a certain user, unless the mailbox of the user overflows, the message is stored in the mailbox.

Therefore, when a user searches for a message in a mailbox, the entire list of stored messages is transferred regardless of whether the message is necessary for the user, and the user can select a desired message from the message list. There was a problem that it took time to find out. In particular, if a message arrives at the user while the mailbox capacity is overflowing, even if the message is necessary for the user, the message cannot be stored in the mailbox. Will be discarded.

Therefore, if the sender does not resend, the message required by the user cannot be received, causing an uncertain problem in receiving.

Accordingly, the present invention provides a message communication system having a mailbox for storing a message in a system, in which various types of information relating to messages that each user does not need are collected and managed in advance, and correspond to the various types of information. When an unnecessary message arrives, the message is discarded without being stored in the mailbox, thereby making effective use of the capacity of the mailbox and ensuring the arrival of the message. An object of the present invention is to provide a message communication system that speeds up access to a message.

[Means for Solving the Problems] In order to solve the problems of the conventional technology, the present invention provides a system in which when a user accesses a message stored in a mailbox, the system does not read the message for the user. Extract message control information such as sender name, subject, and transmission time from the deleted message, create an unnecessary message list based on the message control information, and place the transmitted message in the destination user's mailbox. When storing, the system extracts the message control information from the message, and if the message control information is set in the unnecessary message list, discards the message without storing it in the destination user's mailbox. , A message communication system characterized by maintaining and managing the unnecessary message list. Used.

[Operation] According to the configuration described above, the present invention provides a message communication system having a mailbox for storing a message in a system when a transmitted message is stored in a mailbox of a destination user. , The message control information (various information relating to the unnecessary message) is extracted from the list. If the message control information is set in the unnecessary message list in advance, the message is discarded without being stored in the mailbox of the destination user. Then, when a user accesses a message stored in the mailbox, the system extracts message control information from the deleted message that has not been read out for the user and removes the message control information based on the message control information. A message list is created, the unnecessary message list is maintained and managed, and the effective use of the mailbox and the certainty of the incoming call are ensured, so that the user can quickly access the necessary messages.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing a configuration of a message communication system having a mailbox for storing a message in the system.

In this configuration, an access signal from the user is input,
A communication management unit 1 that performs processing corresponding to the instruction is a message transfer unit 2, an unnecessary message list management unit 3 in which various information on unnecessary messages from each user is collected and managed in advance, and an MB access unit 4 is connected. The unnecessary message list management unit 3 and the MB access unit 4 are connected. Further, the mailbox access unit (hereinafter referred to as MB access unit) 4 is connected to a mailbox (MB) 5 for storing a message.

Next, the operation of the device having this configuration will be described. When a newly subscribed user makes a message search request for a message stored in a mailbox to the message communication system, an MB access unit of the conventional system is used. Similarly, among the messages stored in the mailbox of the user, a message list is extracted from the mailbox MB5 for the message that matches the search condition specified by the user, and passed to the communication management unit 1.

Further, the MB access unit 4 sets the display of the searched message on the MB management table for the message that matches the above search condition.

 FIG. 2 shows a configuration example of the MB management table.

This MB management table contains, for each message identifier,
Position information (address A, word number a) on the external storage device where the retrieved display and message control information are stored, and position information (address AA, word number aa) on the external storage device where the message body is stored ) Is set. The communication management unit 1 transfers the message list passed from the MB access unit 4 to the user.

When the user selects a message from the message list and makes a read request specifying the corresponding identifier, the communication management unit 1 notifies the MB access unit 4 of the user name and the message identifier. The MB access unit 4 extracts the main body of the message from the mailbox MB5 with respect to the specified message identifier and transfers it to the communication management unit 1, as in the MB access unit of the conventional system. Further, the MB access unit 4 sets the MB for the message to be read.
Set the read-out display in the management table. The communication management unit 1 transfers the body of the message passed from the MB access unit 4 to the user.

The operation of the MB access unit 4 when deleting a message is shown in the flowchart of FIG. 3 and will be described in detail.

When the user issues a deletion request specifying a message identifier, the communication management unit 1 notifies the MB access unit 4 of the user name and the message identifier (step S1). It is determined whether or not the message to be deleted has been searched with reference to the MB management table (step S
2). If the message has been searched (YES), it is determined whether the message to be deleted is unread (step S3). If the message has not been searched (NO), step S8 to be described later is executed.
And the deletion process is performed. Here, when the message has not been searched, the message has not been read, and it is logically impossible that the message has been read.

Next, if the message to be deleted in step S3 is not read (YES), the sender name is extracted from the message (step S4), and then whether or not the sender is registered in the unread message management table Is determined (step S5). In that judgment, if it is already registered (YE
S), “1” is added to the number of messages in the unread message management table (step S6), and “1” is further added to the number of unread messages (step S7), and the message identifier specified from the message management table The management information regarding is deleted (step S8).

If it is determined in step 5 that the sender has not been registered (NO), the sender name is registered in the unread message management table (step S9), the number of messages is set to 1 (step S10), and the number of unread messages is set. Is set to 1 (step S1
1).

If it is determined in step S3 that the data has not been read (N
O), the sender name is extracted from the message (step S12), and it is determined whether the sender name is registered in the unread message management table (step S1).
3). If already registered (YES), "1" is added to the number of messages in the unread message management table. If not registered (NO), the process proceeds to step S8, where management information on the specified message identifier is deleted from the MB management table.

FIG. 4 shows a configuration example of the unread message management table.

In the unread message management table, the number of messages and the number of unread messages corresponding to each sender name (A to Z) are set. Here, the number of unread times is the number of times that data has been searched and erased without being read.

FIG. 5 shows a configuration example of the unnecessary message list.

This unnecessary message list is created by extracting message control information such as a sender name from a message deleted without being read for the user and creating an unnecessary message list in which a sender name is set for each item number.

FIG. 6 shows an example of an unnecessary message list or inter-block interface information created or updated periodically or as needed.

In this inter-block interface, when the unnecessary message list management unit 3 notifies the MB access unit 4 of the user name (A), the access unit 4 notifies the unnecessary message list management unit 3 of the unread message management table ( B) is sent out.

The flowchart of FIG. 7 shows the operation of the unnecessary message list described above.

If the contents of the unnecessary message list have been set, the unnecessary message list management unit 3 deletes the setting contents to perform the initial setting (step S20). The unnecessary message list management unit 3 notifies the MB access unit 4 of the user name (step S21), and upon receiving this notification, the MB access unit 4 stores the unread message management table for the user in the unnecessary message list. Hand over to management unit 3 (step
S22). After that, the MB access unit 4 deletes the setting content of the unread message management table and initializes it (step S23).

Next, the unnecessary message list management unit 3 refers to the unread message management table, divides the number of unread messages for each sender name by the number of messages (step S24), and calculates the calculated value n and the preset value m. (Step S2
5) The caller name with the calculated value n larger than the set value m is extracted (YES), and the caller name is set in the unnecessary message list (step S26). If the calculated value n is smaller than the set value m (NO), the process ends without setting.

FIG. 8 shows an example of inter-block interface information when a message arrives between the message transfer unit 2 and the unnecessary message list management unit 3.

That is, the message transfer unit 2 extracts the receiver name and the sender name from the message addressed to a certain user, and notifies the unnecessary message list management unit 3. The unnecessary message list management unit 3 that has received this notification searches whether or not the sender name is registered in the unnecessary message list relating to the called party name, and notifies the message transfer unit 2 of the result (presence or absence).

The flowchart of FIG. 9 shows the processing operation of the message transfer unit 2 when a message arrives.

When a message addressed to a user is transmitted, the message is transferred to the message communication system in which the user is accommodated, and the message transfer unit 2 of the system is activated (step S31). The transfer unit 2 extracts the callee name and the caller name from the message and notifies the unnecessary message list management unit 3 (step S32).

The unnecessary message list management unit 3 having received the notification determines whether or not the sender name received from the message transfer unit 2 is registered in the unnecessary message list for the callee (step S33). To the message transfer unit 2. If the sender name is registered (YES), the message is discarded without being stored in the mailbox of the user (step S34). If the sender name is not registered (NO), the message is stored in the mailbox (step S3).
Five).

The unnecessary message list can be referenced and specified by the user as necessary.

Here, as an element for determining an unnecessary message, in addition to the above-described sender name, a subject included in the message control information, an outgoing time, or a combination thereof can also be used.

Further, the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications and applications can be made without departing from the gist of the invention.

[Effects of the Invention] According to the present invention, in a message communication system having a mailbox for storing a message in the system, various information relating to unnecessary messages is collected and managed in advance for users, and When an unnecessary message corresponding to various types of information arrives, the message is discarded without being stored in the mailbox. It is possible to speed up access to messages required by the user.
