Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a technique for facilitating communication between users using a mobile communication terminal such as a mobile phone. In the present invention, a mobile communication system is a system that includes a mobile communication terminal and a mobile communication network and provides a communication service between mobile communication terminals.

[0002] A mobile communication terminal is a mobile phone or a PHS (Performance).
sonal Handyphone System). A mobile communication network refers to a communication network that relays signals transmitted and received between mobile communication terminals. In addition, a mobile communication network usually includes a base station to which a mobile communication terminal is connected, a mobile communication switch to which the base station is connected, and a management device that stores and manages the communication state of the mobile communication terminal in a state DB. It is comprised including.

[0003]

2. Description of the Related Art In recent years, mobile communication systems for providing communication services between mobile communication terminals (hereinafter, simply referred to as mobile terminals) such as mobile phones and PHSs have been rapidly developed.
The mobile communication system identifies a plurality of areas and supports communication between mobile terminals in each area. The communication state of each mobile terminal is managed by the management device. The mobile terminal is connectable to a base station provided for each area, and when moving to a different area, notifies the management device of the new area via the base station of the destination area.

[0004] With the widespread use of the mobile communication system, it is becoming possible to make a telephone call to a person who wants to contact anytime and anywhere. On the other hand, there is a problem in that the receiver is called regardless of the state, and the caller does not know whether it is good to call the other party. To solve this problem, the user can turn off the mobile terminal if he does not want to receive the call. However, if you turn off the power, you will not be able to receive urgent or important contacts. In addition, even if the user knows that the other party has turned off the power, he or she does not know when it will be possible to talk.

Japanese Patent Laid-Open Publication No. Hei 10-191458 discloses that when the communication status of a caller is "in a call" or "out of service area or power off", the caller can talk. A mobile phone system for notifying a caller is disclosed. Similarly, JP-A-11-27741, JP-A-8-168072, JP-A-8-79387, and JP-A-7-336676 disclose that a mobile communication system has recovered from a call-disabled state. There is disclosed a technique for notifying a caller and, in some cases, connecting to a line.

[0006]

However, Japanese Patent Application Laid-Open Publication No.
The mobile phone system described in Japanese Patent Application Publication No.
The base station of the mobile phone system has functions such as detecting and notifying the communication state of the called terminal. In this case, it is necessary to introduce the function into all base stations of the mobile phone system that are actually operating, which is difficult to realize. Further, since the base station periodically calls the called terminal, a large number of useless calls are generated. Further, it can be said that the mobile phone system merely applies a so-called camp-on service to the mobile communication system, in which the caller requests the other party to make a return call when the mobile phone system returns to the talk-enabled state. Similarly, Japanese Unexamined Patent Application Publication No.
No. 1, JP-A-8-168072, JP-A-8-16872
The technologies described in JP-A-79387 and JP-A-7-336676 are merely applications of the camp-on service to the mobile communication, as described above.

[0007] However, mobile terminals have already been closely linked to business venues and personal lives as a means of communication, and a new need has arisen, namely, a need to perform communication in consideration of the state of the communication partner and privacy. . For example, when making a call, the other party is likely to be busy, so it is desirable to consider etiquette, such as refraining from making calls with less important requirements. Also, when I receive a phone call, I am busy now, so I would like to receive only the urgent requirements and communicate with my own convenience. However, a mobile communication system that provides communication in consideration of user status and privacy has not been realized yet.

An object of the present invention is to provide a communication system which realizes a communication service in consideration of a user state and privacy by notifying a necessary partner of various information.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a status notification system according to the present invention will be specifically described with reference to embodiments. <First Embodiment> FIG. 1 is an overall configuration diagram of a status notification system according to a first embodiment of the present invention. The mobile communication system shown in FIG. 1 includes, in addition to a normal mobile communication system, a notification unit 2 (sending means) and a monitoring unit 3 connected to a mobile communication network.
(Detection means).

The mobile communication system comprises a mobile communication network 1 and a plurality of mobile terminals 11. The mobile communication network 1 includes a base station 12, a mobile communication switch 13, a DB management unit 14, and a state DB 15. The base station 12 transmits and receives signals by connecting to the mobile terminal 11 in a predetermined area. The mobile communication switch 13 transmits and receives data to and from a plurality of base stations, other mobile communication switches, a fixed telephone network, and the like. In addition, the mobile communication exchange 13 notifies the DB management unit 14 of a change in the communication state based on a call request from the mobile terminal.
Notify. The DB management unit 14 records the communication status of the mobile terminal in the status DB 15 according to the notification from the mobile communication exchange. The recorded communication state includes “no communication”, “during a call”, “out of service area or power off”, “where area”, and the like.

(1) Configuration of the Notification Unit 2 FIG. 2 is a block diagram showing the functional configuration of the notification unit 2. The notification unit 2 includes a communication interface (I / F) 2
1, processing unit 22, table management unit 23, storage unit 24, storage unit 2
5 and a sending section 26. First, data stored in the storage unit 24 will be described. The storage unit 24 stores a correspondence table, a qualification table, and a state table. FIG.
Is a conceptual explanatory diagram of a correspondence table. The correspondence table stores the observer address of the observer, the target address of the observation target, and the notification condition in association with each other. Each of the above items is set by an “observer” as described later. Observers
This is the user who receives a notification about the state of another user to be observed. The observation target is a user who is notified of a new state to the observer. As the “observer address” and the “target address”, a communication address that specifies each mobile communication terminal in the mobile communication network is used. In the present embodiment, a telephone number is used as a communication address. The “notification condition” describes a condition in which the state of the observation target is notified to the observer when the state of the observation target is set. For example, if the “notification condition” is “all”, a new state is notified to the observer whenever the state of the observation target changes. If the "notification condition" is "communicable", the observer is notified when the communication state of the observation target becomes "communicable". The case where “communication is possible” may be considered, for example, when the mobile terminal to be observed enters “range”, or when the communication ends during a call and the state becomes “no communication”.

FIG. 4 is a conceptual explanatory diagram of the qualification table. The qualification table stores target addresses, observer addresses, notification conditions, and actions in association with each other. Each of the above items,
As described later, it is set according to the observation target. The “target address” and the “observer address” are the same as in the correspondence table. However, in the “notification condition”, a condition that the observation target user permits the observer to notify or a condition that the observation target user does not permit the notification is set.

The "operation" describes whether the state of the observation target can be notified to the observer when the state of the observation target matches the "notification condition". For example, consider a case where the “notification condition” is “communicable” and the “operation” is “permitted”. In this case, it is permitted to notify the observer that the state of the observation target has become “communicable”. In other words,
It is permitted to register a “notification request” described later in the correspondence table. When the “notification condition” is “all” and the “operation” is “non-permitted”, the state of the observation target is not notified to the observer at all. In other words, registration of a “notification request” described later in the correspondence table is not permitted.

It should be noted that only the notification conditions to be permitted are registered in the qualification table, and all cases that are not registered in the qualification table are “non-permitted”.
It may be. Only notification requests from explicitly authorized parties are registered in the correspondence table. It is preferable from the viewpoint of protecting privacy. FIG. 5 is a conceptual explanatory diagram of the state table. The status table includes the user name, communication address, status 1 and status 2
Are associated and held. In the present embodiment, the communication state of the user notified from the monitoring unit 3 is set in “state 1”. That is, “no communication”, “during a call”, “service area”, “out of service area or power off” and the like. In “state 2”, the own state of the user of each mobile terminal is described. For example, "overnight", "always available", "emergency only available", and the like. In the “state 2”, for example, the user can notify the notification unit 2 from the mobile terminal. In addition, the notification unit 2 notifies a user state automatically detected using an existing user state detection system or the like.
Can also be sent to In the present embodiment, each mobile terminal notifies the notification unit 2 of the user's own state by a self-state notification in a predetermined format.

It is also conceivable that a plurality of communication addresses are registered for one user. In this case, when the self-status of each user is notified, "status 2" of the corresponding communication address may be updated collectively using the user name as a key. It is possible to avoid the contradiction that the user's own state is different for each mobile terminal even though the user is the same. Communication I
/ F21 transmits / receives data to / from a mobile communication network. That is, the communication I / F 21 sends the received data to the processing unit 22. The communication I / F 21 sends the data received from the sending unit 26 to the mobile communication network 1.

The processing section 22 performs processing according to the received data. When the processing unit 22 receives a status notification about any user from the monitoring unit 3, it determines a notification destination based on the correspondence table and creates a notification message in which the user status is described. The processing unit 22 performs the same processing when receiving the self-state notification from the mobile terminal. Processing unit 22
Determines whether the notification destination can receive the notification message based on the state table, and sends the notification destination and the notification message to the storage unit 25 if the notification destination cannot be received.

The processing unit 22 instructs the table management unit 23 to update the status table based on the status notification from the monitoring unit 3 or the self status notification from the mobile terminal. The status notification and the self status notification will be described later. Further, when the processing unit 22 receives a notification request or a notification cancellation request described later from the mobile terminal, the processing unit 22 instructs the table management unit 23 to update the correspondence table based on the qualification table. When updating the correspondence table, the processing unit 22 also notifies the monitoring unit 3 of the updated content. Further, when the processing unit 22 receives a qualification registration request described later, the processing unit 22 instructs the table management unit 23 to update the qualification table.

The table management unit 23 updates the correspondence table, the qualification table and the status table according to the instruction from the processing unit 22. The storage unit 25 temporarily stores the notification message when the notification destination of the notification message cannot receive the message. The storage unit 25 sends the stored notification message to the sending unit 26 according to the instruction from the processing unit 22. The sending unit 26 sends the notification message sent from the processing unit 22 or the storage unit 25 to the designated notification destination.

(2) Configuration of the Monitoring Unit 3 FIG. 6 is a block diagram showing the functional configuration of the monitoring unit 3. In the present embodiment, the monitoring unit 3 is incorporated in the DB management unit 14. The DB management unit 14 manages the DBMS (Databa
se Management System), and manages the state DB 15 that holds the communication state of the mobile terminal. The DB management unit 14 transmits and receives the communication state via a communication interface (I
/ F).

The monitoring unit 3 has a monitoring table 31, a detection unit 32, and a change notification unit 33. FIG. 7 is a conceptual explanatory diagram of the monitoring table 31. The monitoring table 31 stores target addresses and notification conditions in association with each other. Monitoring table 31
Is updated in response to the correspondence table update notification received by the detection unit 32 from the notification unit 2. Therefore, the observation target, the target address, and the notification condition stored in the monitoring table 31 match each item of the correspondence table.

The detection unit 32 is incorporated in the DBMS, and can detect a write command to the state DB. Detection unit 32
Detects the command, determines whether or not to notify the notification unit 2 of a new communication state based on the monitoring table 31.
That is, the detecting unit 32 determines whether the user whose communication state has changed is an observation target and whether the new communication state matches the notification condition. When determining to notify, the detecting unit 32 notifies the new communication state and the observation target of the change notification unit 33.
To send to. The change notification unit 33 creates a state notification in a predetermined format in which the communication state and the observation target are described,
To send to.

(3) Configuration of Mobile Terminal (3-1) Configuration Next, the mobile terminal will be described. The mobile terminal generally includes a storage unit, a storage management unit, a communication control unit, a communication unit, and a user I / F unit (not shown). The storage unit stores the received text message, telephone directory, own terminal information, and the like. The telephone directory usually stores a communication partner and a communication address in association with each other. The storage management unit writes and reads information to and from the storage unit. The communication control unit
Performs processing according to external signals and user operations. The communication unit transmits and receives signals to and from a mobile communication network. The user I / F unit receives an operation from a user and notifies the user of information by voice or display.

In this embodiment, in addition to the name and telephone number of the communication partner, the user state is stored in the telephone directory information. FIG. 8 is a conceptual explanatory diagram of a telephone directory holding a user state. The telephone directory holds a name, a telephone number, a registration flag, a state 1 and a state 2 in association with each other. The “registration flag” indicates whether or not the status of the communication partner is notified. If the “registration flag” is “ON”, a predetermined state of the communication partner is notified to the mobile terminal.
If "OFF", the state of the communication partner is not notified.
"State 1" corresponds to state 1 in the state table, and the notification unit 2
Describes the communication state of the mobile terminal notified to. “State 2” corresponds to state 2 in the state table, and describes the own state notified by each mobile terminal to the notification unit 2.

FIG. 9 is a display example of a user state in a mobile terminal having the telephone directory. FIG. 9 shows that "Taro Fujitsu" is in the service area and wants to make a phone call at night. In addition, "Hanako Fujitsu" is currently "calling", indicating that a call can be made at any time. Although “state 2” is displayed as an image in FIG. 9, a display using a text message is also possible. Note that the mobile terminal shown in FIG. 9 has select buttons 101 and 102 and a confirm button 103.

(3-2) Example of Screen Next, an operation of selecting a communication partner and requesting or canceling the user state notification in the mobile terminal will be described with reference to an example of the screen of FIG. Typically, on mobile terminals,
A predetermined operation such as mail or telephone directory editing can be selected on the main menu. In the present embodiment, “notification request / cancellation”, “qualification registration”, and “own state notification” are displayed on the main menu in addition to the normal operation.

(3-2-1) Example of notification request / cancel screen When "notification request / cancel" is selected in the main menu of FIG. 10 (a), a "partner selection window" shown in FIG. 10 (b) is displayed. Is done. In this window, ON / OFF of the registration flag is displayed for the communication partner. In the figure, it is displayed that the registration flag has already been turned on for “Taro”. When any communication partner is selected, a “notification condition window” shown in FIG. 10C is displayed.

The notification condition window accepts selection of any one of the notification conditions of “all”, “communication state”, and “user state”. When "all" is selected, notification of a new state is set for all state changes occurring in the communication partner. When "communication state" is selected, for example, a pull-down menu is displayed, and the communication state desired to be notified can be selected. The bull down menu displays communication states such as "all", "service area", "out of service area or power off", "busy", and "communicable". When "user state" is selected, for example, a pull-down menu is displayed, and the user state desired to be notified can be selected. In the pull-down menu, user states such as "all", "overnight", "always available", and "urgent only" are displayed. A plurality of selections may be accepted in the pull-down menu. FIG. 10 shows a case where “all” is selected as the notification condition.

After the notification condition is set, the process returns to the "partner selection window" again (FIG. 10D). Here, the registration flag is turned on for the newly selected “Hanako”. If another communication partner wants to be notified of the status, the other communication partner and the notification condition are selected in the same manner as described above. Also, when changing the notification condition for the communication partner whose registration flag is already turned on, the communication partner and the notification condition are selected in the same manner as described above.

For example, when the confirmation of the notification request is instructed by pressing the confirmation button twice in succession, the notification request is transmitted to the notification unit 2. Then return to the main menu (Fig. 10
(E)). When the notification unit 2 does not receive the transmitted notification registration, a predetermined message shown in FIG. 10F is displayed. Cancellation of the notification request can be set in the same manner as described above.

(3-2-2) Qualification Registration Screen Example Next, an operation for setting the qualification table of the notification unit 2 from the mobile terminal will be described with reference to a screen example. FIG. 11 is a screen example showing the setting of the qualification table. When "qualification registration" is selected in the main menu (FIG. 11 (a)), a "partner selection window" of FIG. 11 (b) is displayed. When a communication partner is selected, a “qualification setting window” shown in FIG. 11C is displayed. This window accepts a selection of whether or not to notify the status of the selected communication partner. When either is selected, FIG.
The “condition setting window” shown in (d) is displayed.

The “condition setting window” accepts setting of a state in which notification is permitted or not permitted. The state can be selected from any of "all", "communication state", and "own state". Each state is the same as "all", "communication state", and "user state" in the notification condition window of FIG. When "communication state" or "own state" is selected, similar to the notification condition window,
A pull-down menu or the like is displayed so that a detailed state can be selected. FIG. 11 shows a setting of “permitting” to notify the selected communication partner of the state in which “communication is possible”. With this setting, self-status notification is not allowed.

Next, a "setting confirmation window" shown in FIG. 11E is displayed. When "OK" is selected, a qualification registration request is transmitted to the notification unit 2, and a display indicating that the setting has been completed is performed (FIG. 11F). When "correction" is selected, for example, the screen returns to the "qualification setting window" in FIG. 11C and the setting can be performed again. (3-2-3) Screen example of self-state notification FIG. 12 is a screen example when the self-state is notified to the notification unit 2 in the mobile terminal. When "notification of self status" is selected in the main menu (FIG. 12A),
The “state selection window” shown in FIG.
In the “state selection window”, state options such as “overnight”, “always available”, and “urgent only” are displayed together with images. When, for example, the confirm button is pressed in a state where any of the states is selected, a self-state notification is transmitted to the notification unit 2.

[Processing Flow] Next, the flow of processing performed in the status notification system of this embodiment will be described. (1) Process Performed by Notification Unit 2 FIG. 13 is a flowchart illustrating a flow of a process performed by the notification unit 2.

In step S201, the communication I / F waits for reception of a signal. Upon receiving the signal, the communication I / F sends the received signal to the processing unit 22. Step S2
In 02, the processing unit 22 performs a process according to the received signal. First, the processing unit 22 determines whether or not the received signal is a status notification from the monitoring unit 3 or a self status notification from the mobile terminal. If “Yes” is determined, step S
Move to 204. If "No" is determined, the process proceeds to step S212 described later.

In step S203, the processing unit 22 writes the communication state of the mobile terminal or the user's own state based on the received state notification or own state notification. In step S204, when the received notification is a status notification, the processing unit 22 determines whether or not the notification is that the signal can be received. For example, this is a notification that the communication state has been changed to “range” or “no communication”. If “Yes”, step S2
Move to 05. Whether the received notification is a self-state notification,
Alternatively, if it is another status notification, step S20 described later
Move to 7.

In step S205, the processing unit 22 notifies the storage unit 25 of the mobile terminal that has become able to receive. The storage unit 25 determines whether a notification message addressed to the notified mobile terminal is stored. If the data is stored, the process proceeds to step S206. If not,
The process proceeds to step S207 described below. Step S20
In 6, the storage unit 25 sends the stored notification message to the mobile terminal via the sending unit 26. That is, a new user state is notified to the mobile terminal that has not been notified of the notification message because it is in a state where reception is impossible. When a plurality of notification messages relating to the same other mobile terminal are stored for the same mobile terminal, the storage unit 25 transmits only the latest notification message and deletes the other notification messages. May be.

In step S207, the processing section 22 determines a notification destination to be notified of a new user state based on the correspondence table. First, the processing unit 22 instructs the table management unit 23 to read the observer's address and its notification condition. The table management unit 23 reads, from the correspondence table, the address and notification condition of the observer who has designated the user whose status has changed as the observation target, and notifies the processing unit 22 of the address. Processing unit 22
Determines, from among the notified observers, an observer whose new user state matches the notification condition as a notification destination.

In step S208, the processing unit 22 determines whether or not the notification destination determined in step S207 can receive the notification message based on the status table. First, the processing unit 22 notifies the table management unit 23 that the state table has been read. The table management unit 23 reads out the state of the determined destination mobile terminal and sends it to the processing unit 22. Processing unit 2
When the notification destination is receivable, a notification message of a predetermined format for the notification destination is created and transmitted to the transmission unit 26 together with the notification destination address. After that, the procedure moves to step S209. If the notification destination cannot be received, the process proceeds to step S210 described later.

In step S209, the sending unit 26 sends a notification message to a notification destination address. Step S
At 210, the processing unit 22 sends the notification destination and the notification message to the storage unit 25. The storage unit 25 stores the received notification message and the notification destination in association with each other.

In step S211, the processing unit 22 determines whether a notification message has been sent or stored for all notification destinations. If “No”, the process proceeds to step S208, and the process according to the state of the notification destination is repeated in the same manner as described above. If "Yes", the step S2 is performed.
01, and the above processing is repeated. Step S2
If it is determined that the received signal is not the status notification or the self status notification in step 02, the process proceeds to step S212. In step S212, the processing unit 22 determines whether the received signal is a notification request or a notification cancellation request from any of the mobile terminals. If "Yes" is determined, the process proceeds to step S213.
Move to If "No" is determined, the process proceeds to step S217 described later.

In step S213, the processing unit 22 determines whether to permit the received notification request or notification cancellation request based on the qualification table. That is, the processing unit 22
Receives the notification request, extracts the observation target and the observer, and notifies the table management unit 23. The table management unit 23 reads out the notification condition and operation for the notified observer from the qualification table, and notifies the processing unit 22. The processing unit 22 determines whether to permit the notification request based on the notification condition of the notification request and the read notification condition and operation. If it is determined to permit, the process proceeds to step S214. If it is determined that permission is not given, the process proceeds to step S216.
If a notification cancellation request has been received, it is determined that permission is given.

In step S214, the processing section 22 determines a notification condition to be set in the correspondence table. This determination is made based on the notification condition described in the notification request and the notification condition and operation of the qualification table. Next, the processing unit 22 notifies the table management unit 23 of the determined observer, observation target, and notification condition. The table management unit 23 writes the notification content to the correspondence table. In step S215, the processing unit 22 creates an update notification in a predetermined format in which the observation target and the notification condition are described, and transmits the update notification to the monitoring unit 3 via the transmission unit 26. The monitoring unit 3 updates the monitoring table based on the update notification. Thereafter, the flow returns to step S212 to repeat the above-described processing.

If it is determined in step S213 that the notification request is not permitted, the flow shifts to step S216. In step S216, the processing unit 22 creates a response message indicating that the transmitted notification request cannot be permitted,
The notification is sent to the requesting mobile terminal. On the mobile terminal that has received the response message, the screen illustrated in FIG. 10G is displayed.

If it is determined in step S212 that the received signal is neither a notification request nor a notification cancellation request, the process proceeds to step S217. In step S217, the processing unit 22 determines whether the received signal is a qualification registration request. If "Yes" is determined, the process moves to step S218. If "No" is determined, the process proceeds to step S221 described later.

In step S218, the processing unit 22 determines whether to permit the received qualification registration request based on the target address. Specifically, when the target address matches the communication address of the request source, it is determined that permission is granted. If it is determined to permit, the process proceeds to step S219. If it is determined not to be permitted, a step S22 described later is performed.
Move to 0.

In step S 219, the processing section 22 extracts the contents of predetermined items from the received qualification registration request and sends it to the table management section 23. The table management unit 23 writes the notified contents in the qualification table. In step S220, the processing unit 22 creates, for example, a message indicating that the qualification registration request cannot be permitted and transmits the message to the requesting mobile terminal. Thereafter, the process returns to step S201.

If it is determined in step S217 that the received signal is not a qualification registration request, step S2
Move to 21. In step S221, the processing unit 22 performs another process such as a predetermined error process, and returns to step S201. (2) Process Performed by Monitoring Unit 3 FIG. 14 is a flowchart illustrating the flow of the monitoring process performed by the monitoring unit 3. The following processing is started when the DB management unit 14 is activated.

First, in step S301, the detecting unit 32
Waits for a write command to be issued to the state DB, and proceeds to step S302 when a write command is issued. In step S302, the detecting unit 32 determines whether to notify the communication unit newly written in the state DB to the notification unit 2 based on the monitoring table 31. In other words, the mobile terminal whose communication state has changed is the target of observation,
Then, it is determined whether or not the resulting change meets the notification condition. If "Yes" is determined, the process moves to step S303. If "No" is determined, the process returns to step S301.

In step S303, the detection unit 32 notifies the change notification unit 33 of the new communication state and the new mobile terminal. The change notification unit 33 creates a status notification in a predetermined format and sends it to the notification unit 2. Then, in step S301
Return to The monitoring unit 3 also updates the monitoring table 31 in addition to the monitoring process. That is, upon receiving the update notification from the notification unit 2, the detection unit 32 updates the monitoring table 31. If you receive an update notification based on a notification request,
A process for adding the target address and the notification condition is performed. When an update notification based on the notification cancellation request is received, the corresponding entry is deleted from the monitoring table 31.

(3) Process Performed by Mobile Terminal FIG. 15 is a flowchart showing the flow of a notification request / cancel process performed by the mobile terminal. When the “notification request / cancel” is selected in the main menu, the following processing is started. The display processing of the main menu is the same as the processing in a normal mobile phone or the like, and thus the description is omitted.

In step S401, the user I / F reads out the telephone directory and displays it on the display. At this time, whether or not the registration flag of each communication partner is “ON” is also displayed. In step S402,
The user I / F unit sends the selected communication partner and the notification condition to the communication control unit. That is, the user I / F section
As shown in FIG. 10, the selection of the observation target and the notification condition is accepted. The communication control unit waits for the end of the setting by the user, and proceeds to step S403 when the setting is completed. That is, the communication control unit determines that the setting is completed by pressing the enter button twice in succession.

In step S403, the communication control unit creates a notification request or a notification cancellation request in which the set contents are described, and transmits it to the notification unit 2 via the communication unit. In step S404, the communication control unit waits for a response to the transmitted notification request and the like, and upon receiving the response, proceeds to step S4.
Move to 05. In step S405, the communication control unit performs a process according to the received response. If the setting of the notification request or the like is successful, the process proceeds to step S406. If the setting has failed, the process proceeds to step S497 described below.

In step S406, the communication control unit instructs the storage management unit to update the telephone directory. When the notification request is successful, the storage management unit rewrites the notification flag of the corresponding communication partner to “ON”. Conversely, if the communication request release is successful, the notification flag is rewritten to “OFF”. In step S407, the user is notified that the setting of the notification request or the notification cancellation request has failed (see FIG. 10).
(G)).

<Other Embodiments> (A) In the above embodiment, the monitoring unit 3 is integrated with the DB management unit 14. However, if the monitoring unit 3 can monitor a change in the state DB, the monitoring unit 3 is not necessarily required to use the DB management unit
It does not have to be configured integrally with In addition, the notification unit 2 only needs to be able to receive the status notification from the monitoring unit 3 and transmit a notification message to the mobile terminal, and does not necessarily need to be on the mobile communication network.

(B) In the above embodiment, the detection unit 32 is
The monitoring unit 3 is configured by being incorporated in the BMS. But,
A configuration in which the detection unit 32 is provided outside the DBMS is also possible. In this case, the detection unit 32 refers to the update history of the state DB held by the DBMS at predetermined time intervals, and compares the update history with the previous update history. As a result of the comparison, when it is determined that a change has occurred in the state DB, the detecting unit 32 determines based on the monitoring table 31
It is determined whether the new communication state is to be notified to the notification unit 2 or not.

(C) When setting the notification request and the qualification registration in the correspondence table and the qualification table, it is preferable that the validity time can be set together. The notification unit determines whether there is an entry for which the effective time has elapsed at predetermined time intervals, and deletes the corresponding entry from the table. The work of canceling the notification request and canceling the qualification registration is reduced. In addition, it is possible to prevent an increase in the load on the network due to the cancellation of the notification request or the like.

(D) A configuration in which a plurality of notification units 2 are provided for the monitoring unit 3 is also conceivable. For example, there is a case where a provider that provides a mobile communication network provides a service for notifying a user state to mobile terminals connected to different mobile communication networks. In this case, the monitoring unit 3 is provided with a notification unit corresponding to each mobile communication network. In the monitoring table of the monitoring unit 3, the identification information of the notification unit is registered in association with the target address. When a state change that matches the notification condition occurs at a target address, the monitoring unit 3 notifies the notification unit associated with the target address of the state change that has occurred.

(E) FIG. 16 is an overall configuration diagram according to another embodiment of the status notification system of the present invention. In the status notification system of the present embodiment, a mobile communication network 1 and a computer network 5 such as the Internet are connected via a gateway device 4. The mobile communication network 1 is provided with a monitoring unit 3. An information terminal 51 having a user state detection device (not shown) is connected to the Internet 5. The user state detection device operates on the information terminal, detects the user state based on the activation state of the screen saver, the frequency of input to the application, the user's schedule, the position of the user detected by infrared rays, and outputs the detection result to the outside. Can be sent.

The gateway server 4 has a collection server 41
And the notification unit 2 are connected. The collection server 41 collects the user status from the information terminal 51 via the Internet 5 and stores the user status in the all status DB 42. For example, there are user states such as “at present”, “at a meeting”, “mute”, “busy”, “on a business trip”, and the like. In addition, the collection server 41
Receives the status notification from the monitoring unit 3 and the self status notification from the mobile terminal in place of the notification unit 2, and stores the user status on the mobile communication network 1 in the all status DB. That is, the collection server 41 centrally manages, for one user, the state collected on the Internet and the state collected on the mobile communication network.

The notification section 2 has the same configuration as the configuration in the first embodiment. However, an all state DB 42 managed by the collection server is used instead of the state table. In addition, the notification unit 2 monitors a state change of the all state DB 42, and when a change occurs in the all state DB 42, transmits a notification message to the mobile terminal 11 based on the correspondence table. In the correspondence table and the qualification table, other addresses such as an IP address in addition to the telephone number of the mobile terminal can be used as the addresses of the observer and the observation target. The notification unit 2 determines the notification destination of the occurred change based on the correspondence table, as described above. In this case, the user status to be notified to the mobile terminal can be the most appropriate notification destination address according to the user status. For example,
When the communication state of the observation target is “out of service area or power off”, it is conceivable that the user's e-mail address or business trip phone number is changed to the communication state and notified. In addition, the mobile terminal can be notified of the user's own state detected by the user state detection device on the information terminal. For example, "in a meeting", "remote seat", and the like.

Conversely, the notification unit can also transmit the communication state on the mobile communication network 1 and the user's own state to the information terminal 51 based on the correspondence table. By associating the user information managed by the user state detection device or the address book system operating on the information terminal 51 with the user information on the mobile communication network, the user state on the mobile communication network 1 on the application Can be referred to.

Further, in the present embodiment, settings such as a notification request, a notification cancellation request, and a qualification registration request can be made on the information terminal on the Internet, and the operation of each setting is facilitated.

[0085]

According to the present invention, a user using a mobile terminal can know the state of a communication partner in advance, and can make a call in consideration of the state of the partner. Also, the user
Since the communication partner can be selectively notified of his / her status, his / her privacy can be protected.
