DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a system for notifying of information arrival in a communication system for transmitting and receiving information such as electronic mail.

[0002]

2. Description of the Related Art In recent years, communication systems for transmitting and receiving e-mails by information communication terminals have become widespread. In e-mail communication using a general personal computer or the like as an information communication terminal, an information communication terminal (mail client)
To the public line network (wired telephone network such as ISDN / PSTN or wireless telephone network) or the leased line network.
P connection (Dial-up IP connection by PPP, etc.)
Then, a mail server (SMTP / POP3 server or the like) is accessed via a TCP / IP network (so-called Internet), and after the mail server performs password authentication and the like, the mail server mail is sent in response to a request from the mail client. E-mail data is transferred from the box to the mail client. Then, the e-mail data received by the mail client is stored, and the recipient opens and browses the e-mail.

As an information communication terminal, a portable communication terminal (for example, Japanese PHS: Personal Handyphone System) is used.
m, PDC: Personal Digital Cellular Telecommunication
tionSystem, DECT in Europe: Digital European Cordl
ess Telecommunication, GSM: Global System Mobil
e, also in e-mail communication using a mobile communication system such as IS-95 in the United States), a mail client accesses a mail server as needed and takes in the e-mail data transferred from the mail server. A so-called pull-type e-mail system, which is stored in each terminal, is generally used.

In a closed communication network (for example, an intranet) constructed by a company or the like, a line connection is always established, and a mail server or a branch line LAN such as a branch office is provided as a center device of the closed communication network. The e-mail is delivered using a mail server and the like, and is directly transferred to the mailbox of the mail client. The recipient has then opened and viewed the email.

Therefore, in the above-described electronic mail communication, the mail client cannot immediately know that the electronic mail to itself has been delivered. That is, the recipient can know the reception of the electronic mail only by the mail check operation from the mail client.

In order to solve this inconvenience, in e-mail communication using a portable communication terminal, when an e-mail is delivered, a mail server directs a corresponding mail client (e-mail address) to a corresponding e-mail client (e-mail address). 2. Description of the Related Art A mail arrival notification service that transmits information by an electronic mail system (such as a short mail) to notify an incoming call has been implemented. Recently, when an e-mail is received, a so-called push-type e-mail in which the mail server notifies the mail client of the arrival of the e-mail and actively distributes the e-mail data. Systems are also being used.

In such an incoming call notification service and push-type e-mail system, when a large number of e-mails are received at a certain mail client, a large number of incoming notifications are issued in a short time. Frequent incoming call notification and e-mail check for it are troublesome. In order to solve this problem, for example, a sender sends an e-mail with an e-mail attribute such as "urgent" or "normal", and the mail server determines the e-mail attribute and sends the urgent e-mail. A method of performing only the incoming call notification can be considered. By the way, the attributes such as “urgent” and “normal” tend to be different between individual mail senders and mail recipients, and an e-mail urgently required by the sender is particularly urgent for the recipient. There may be no case and vice versa.
For this reason, the reliability of communication by e-mail may be impaired.

As an example of an improvement proposal for improving the reliability of such communication, for example, Japanese Patent Application Laid-Open No. H11-154975, “E-mail Apparatus” is known. In this publication example, the portable communication terminal device determines the urgency of the delivered e-mail based on the determination conditions (for example, sender address, subject, specific password collation, etc.), The reception of the high e-mail is notified to the user of the portable communication terminal device. This enables quick e-mail communication.

[0009]

However, in the above-mentioned publication, although the presence or absence of urgency can be determined and notified,
When changing the degree of urgency for the judgment matter in the mobile communication terminal device, it is necessary to reset the urgency, and the setting operation is troublesome. Therefore, there is a disadvantage that operability is poor.

Furthermore, in the publication example, since the urgency of the incoming e-mail is determined by the portable communication terminal device, it is necessary to mount a CPU, a memory, etc. capable of performing control processing corresponding to the urgency. In particular, in the case of small-sized portable communication terminals such as PHS and PDC, the scale of signal processing and the size of the device are increased, and it is considered that it is difficult to meet the demand for miniaturization and multifunctionality.

[0011] The present invention is to solve such a problem in the prior art. In an information communication terminal, for example, when receiving information such as an electronic mail, an information arrival notification condition based on the acquired information content is generated. It is possible to appropriately update the information arrival notification condition by transmitting the information to the arrival notification server, thereby improving the operability of the information communication terminal,
Provided is an information reception notification method and information reception notification system, an information reception notification system, an information communication terminal, and an information recording medium in a communication system capable of performing an appropriate reception notification based on an information reception notification condition for distributed information. With the goal.

Hereinafter, several embodiments of the update operation of the alert condition will be described in detail. The alert condition is whether or not to notify the destination portable communication terminal 1 that an e-mail of certain information has been received, that is, the user of the destination portable communication terminal 1 receives the e-mail of the information content. This indicates a condition for determining whether or not the incoming call notification is desired, and a condition including the priority of the incoming call notification set on the information content on the mobile communication terminal 1 side is set.

FIG. 4 is a functional block diagram showing a first embodiment of the update operation of the alert condition. Each illustrated function is realized mainly by the operation of the control unit 32 of the center server 16 and the control unit 25 of the mobile communication terminal 1.

The center server 16 stores alert conditions (hereinafter referred to as alert condition personal profiles) individually stored and set for each mail address or telephone number of the mail client (portable communication terminal 1). Stored in the unit 43, the alert server 1
In response to the reference request of No. 5, the corresponding alert condition personal profile is read out and output. This alert condition personal profile is stored in association with a database of mail addresses and telephone numbers assigned to each mobile communication terminal 1. The alert condition personal profile may be stored on the alert server 15 side.

The alert conditions include (a) sender information such as the sender's mail address and telephone number, (b) a predetermined keyword existing in the e-mail, (c) reception time interval of the e-mail, (d) ) Use the number of received mails. The case where each condition is used will be described in detail in the following embodiments.

The mobile communication terminal 1 receives electronic mail information distributed from the mail server 17 by the mail receiving unit 51 and an alert distributed from the alert server 15.
In addition, the alert condition change request unit 52 generates a change request for an alert condition and inputs a setting operation related thereto. The alert condition determining unit 53 determines and analyzes the alert condition based on the information content included in the received e-mail and the alert condition change request, and the alert condition setting unit 54 determines the alert condition according to the determination analysis result. Configure the alert condition change settings. Then, the alert condition notifying unit 55 sends the changed alert condition to the center server 16.

In the present embodiment, the request for changing the alert condition is triggered by the occurrence of an event (event occurrence) due to the reception of the e-mail information. That is, when the e-mail information is received by the e-mail receiving unit 51, a request for changing the alert condition is generated, and the alert condition is changed and set based on the information content regarding the received e-mail.
For example, based on the control of the control unit 25, the alert condition change request unit 52 asks "Do you want to change the incoming call notification condition?"
For example, a change setting confirmation character such as "Do you want to notify the incoming mail of this received mail?" Is displayed on the display unit 29, and the user is urged to perform a change request operation from the input operation unit 28 to wait for input. In this way, by starting the alert condition change request operation when an event occurs, the user can perform a passive operation such as YES / NO, so that the alert condition can be easily changed by a simplified operation procedure. And the operability can be improved.

The center server 16 receives the changed alert condition sent from the portable communication terminal 1 by the alert condition personal profile analysis unit 41 and analyzes it as information to be registered. The alert condition personal profile setting unit 42 changes the alert condition personal profile according to each user or terminal according to the determination analysis result, and the alert condition personal profile storage unit 43 previously stores the alert condition personal profile. The alert condition is changed to the changed alert condition and updated, and the updated alert condition is stored and retained. Thereby, the mobile communication terminal 1
It is possible to update the alert condition as needed in response to the request of the user having the information. After that, based on the updated alert condition, the distribution of the alert regarding the arrival of the e-mail is performed to the mobile communication terminal 1.

In this embodiment, the mobile communication terminal 1 does not manage the determination of the alert notification of the incoming e-mail and the update of the determination condition (alert condition). The configuration can be simplified, and downsizing can be achieved while suppressing an increase in cost. Further, when updating the alert condition, the alert condition can be updated by a simple operation on the mobile communication terminal 1, so that a troublesome setting operation is not required, the operability can be improved, and the burden on the user can be reduced. Further, the mobile communication terminal 1 does not need to be equipped with a CPU, a memory, and the like that can execute processing control for updating the alert condition, and can easily respond to a demand for multifunctionality. Then, according to the alert condition updated as desired by the user on the receiving side, it is possible to distribute the incoming notification of the e-mail that the receiving side wants to acquire.

FIG. 5 is a functional block diagram showing a second embodiment of the alert condition update operation. The second embodiment shows a case where caller information is used as a specific example of the first embodiment. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.
