Description

  The present invention relates to a communication management method and a communication management server, and more particularly to a communication management method and a communication management server in which a caller terminal device designates a predetermined notification target terminal device and notifies a message.

  For example, when you want to contact the recipient's mobile terminal device (portable terminal device) for reasons such as urgent requirements, the standby state of the recipient's mobile terminal device is a mode that prohibits vibration or voice, for example There is a problem that simply making a call makes it difficult for the recipient to notice and delays the response. As a method for solving this problem, a method is known in which the volume or vibration state of a mobile terminal device at the time of an incoming call is changed according to the presence (current state) of the recipient (see, for example, Patent Document 1).

In addition, when the receiver cannot communicate with the receiver because the telephone cannot be talked, the sender needs to repeat the call repeatedly until the telephone can be talked. For this reason, a method of repeating retransmission a predetermined number of times until a communication partner can be connected is known (see, for example, Patent Document 2).
JP 2005-303668 A JP 2003-271931 A

  However, the method described in Patent Document 2 has a problem in that communication resources (communication bandwidth) are wasted because the same message is simply retransmitted regardless of the recipient's situation.

  The present invention has been made in view of these points, and an object of the present invention is to provide a communication management method and a communication management server that can effectively utilize communication resources.

In order to solve the above problem, the present invention provides a communication management method as shown in FIG.
The communication management device 1 is used by the sender terminal device 2 to specify a notification target terminal device (recipient terminal device) 3 and notify a message.

The communication management device 1 manages the presence information of the notification target terminal device 3.
When the communication management device 1 receives a notification request for a message transmitted from the caller terminal device 2, the communication management device 1 acquires presence information and transmits the first message to the notification target terminal device 3.

  And the communication management apparatus 1 transmits a 2nd message to the notification object terminal device 3, whenever the notification object terminal apparatus 3 receives the presence information update request output according to the presence change.

And the communication management apparatus 1 will complete | finish transmission of the 2nd message with respect to the notification object terminal device 3, if the response with respect to the 2nd message from the notification object terminal device 3 is received.
According to such a communication management method, when a notification request for a message transmitted from the caller terminal device 2 is received by the communication management device 1 (step S1), presence information is acquired (step S2). Is transmitted to the terminal device 3 to be notified (step S3). Each time a presence information update request output in response to a change in presence by the notification target terminal device 3 is received by the communication management device 1 (step S4), a second message is transmitted to the notification target terminal device 3. (Step S5). And if the response with respect to the 2nd message from the notification object terminal device 3 is received by the communication management apparatus 1 (step S6), transmission of the 2nd message with respect to the notification object terminal device 3 will be complete | finished.

  In order to solve the above problem, in the communication management server used when the caller terminal device designates a predetermined notification target terminal device and performs message notification, the caller terminal device notifies the message. A notification request receiving means for receiving a message notification request output at the time, a presence information receiving means for receiving the presence information from a presence management server for managing presence information of the terminal device to be notified, and a notification of a first message Each time the presence information receiving means receives updated presence information transmitted to the target terminal device and output by the presence management server in response to a change in presence of the notification target terminal device, a second message is sent to the target terminal device. A transmission means for transmitting to the notification target terminal device; and the second message from the notification target terminal device. Response message receiving means for receiving a response to the message, and message ending means for ending transmission of the second message to the terminal device to be notified when the response message receiving means receives the response. A communication management server is provided.

  According to such a communication management server, the notification request receiving unit receives a notification request for a message transmitted from the caller terminal device. The presence information receiving means receives presence information from a presence management server that manages presence information of the terminal device to be notified. Thereafter, the transmission unit transmits the first message to the notification target terminal device. Further, whenever the presence information receiving means receives updated presence information output by the presence management server in response to a change in the presence of the notification target terminal apparatus, the communication means transmits a second message to the notification target terminal apparatus. The Then, the response message receiving means receives a response to the second message from the notification target terminal device. When the response is received by the response message receiving unit, the message ending unit ends the transmission of the second message to the notification target terminal device.

  According to the present invention, since a message corresponding to a change in presence is transmitted to the notification target terminal device, the message can be notified efficiently, and communication resources can be used effectively.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
First, the outline of the invention applied to the embodiment will be described, and then the specific contents of the embodiment will be described.

FIG. 1 is a principle diagram showing the invention applied to the embodiment.
The communication management system shown in FIG. 1 includes a communication management device 1, a caller terminal device 2, and a notification target terminal device 3, and the caller terminal device 2 designates the notification target terminal device 3 as a message. This is an example of a system used when performing the notification. This system operates according to the communication management method of the present invention.

  The caller terminal device 2 transmits a notification request for a message to be notified to the notification target terminal device 3 to the communication management device 1. Examples of the caller terminal device 2 include a dial-type fixed telephone, an IP telephone, a mobile phone, a PC (Personal Computer), and a PDA (Personal Digital Assistants).

  The notification target terminal device 3 has a communication function with the communication management device 1. The notification target terminal device 3 transmits a presence information update request to the communication management device 1 in accordance with a change in its presence. In addition, the notification target terminal device 3 transmits a response to the message to the communication management device 1 by an operation from the notification target person (recipient).

Examples of the notification target terminal device 3 include those similar to those exemplified as the caller terminal device 2, but those having portability such as a mobile phone and a PDA are particularly preferable.
The communication management device 1 has a function of managing presence information of the notification target terminal device 3. Upon receiving the notification request for the message transmitted from the caller terminal device 2, the communication management device 1 acquires (removes) presence information and transmits the message (first message) to the notification target terminal device 3. Further, the communication management device 1 transmits a message (second message) to the notification target terminal device 3 every time it receives a presence information update request. Further, when a response to the message from the notification target terminal device 3 is received, the transmission of the message to the notification target terminal device 3 is terminated.

  According to the communication management method operated by such a communication management system, when the communication management device 1 receives a notification request for a message transmitted from the caller terminal device 2 (step S1), presence information is acquired ( In step S2), a message is transmitted to the notification target terminal device 3 (step S3). Whenever the presence information update request output in response to the presence change is received by the notification target terminal device 3 by the communication management device 1 (step S4), a message is transmitted to the notification target terminal device 3 (step S4). Step S5). That is, this message is repeatedly transmitted to the terminal device 3 to be notified according to the presence information. And if the response with respect to the 2nd message from the notification object terminal device 3 is received by the communication management apparatus 1 (step S6), transmission of the 2nd message with respect to the notification object terminal device 3 will be complete | finished.

  Since there is a high possibility that the communication state of the notification target terminal device 3 will change as the presence state changes, in this way, a message is transmitted to the notification target terminal device 3 in accordance with the presence change of the notification target terminal device 3. When there is a high possibility of being able to communicate, it is possible to efficiently notify a message by performing retransmission, thereby suppressing wasteful use of communication resources and effectively using communication resources. In particular, when a message corresponding to a change in the presence of the notification target terminal device 3 is transmitted to the notification target terminal device 3, for example, by transmitting a message in consideration of the recipient, the message can be notified more efficiently. .

Hereinafter, embodiments of the present invention will be specifically described.
FIG. 2 is a block diagram illustrating the communication management system according to the first embodiment.
In the communication management system 500, a plurality of mobile terminal devices (in this embodiment, mobile terminal devices 21, 22, and 23) are connected to the carrier center 100 via the mobile terminal carrier network 10. The carrier center 100 manages presence information of the mobile terminal devices 21 to 23.

  A push-type telephone 31 is connected to the carrier center 100 via the public telephone network 20, and a PC 41 is connected via the Internet 30. A packet network 40 is connected to the Internet 30, and a portable terminal device 51 is connected to the carrier center 100 via the packet network 40 and the Internet 30.

  Here, the mobile terminal devices 21 to 23 constitute the notification target terminal device 3 of FIG. 1, that is, the receiver's mobile terminal device (hereinafter referred to as “target terminal device”) to be notified, and the push-type telephone 31. The PC 41 and the mobile terminal device 51 constitute the caller terminal device 2 of FIG. 1, that is, the caller's terminal device. The target terminal device and the caller's terminal device are not limited to the above examples as long as they can communicate with the carrier center 100.

  In this communication management system 500, the caller (calling side) is one of the mobile terminal devices 21, 22, 23 of the receiver (receiving side) using any one of the push-type telephone 31, the PC 41, and the portable terminal device 51. Emergency notification (message notification) is made to one or more. Hereinafter, the recipient is also referred to as a “user”.

  When using the push-type telephone 31, the caller performs an operation according to a predetermined method, and when using the PC 41 or the mobile terminal device 51, for example, an emergency application to be notified to the receiver by using a dedicated application or the like. An emergency notification request designating the urgency level indicating the responsiveness, the response method executed in accordance with the presence of the user using the target terminal device, and information for specifying the target terminal device or the user is transmitted to the carrier center 100 .

  In this embodiment, there are three types of urgency: low urgency (low), low urgency (low), next low urgency (medium), and high urgency (high). Specify one of the degrees.

The response method is designated when different reactions are desired when the receiver can talk and when the receiver has difficulty in talking.
Upon receiving the emergency notification request, the carrier center 100 transmits an emergency signal (first message) to the target terminal device. In addition, regardless of the timing of the first message transmission, the target terminal device detects the presence change or transmits the information as a presence information update request at a predetermined timing. When there is a presence information update request for updating presence information from the device, the presence information is updated. When the presence information update request is received after the first message transmission, a new emergency signal (second message) corresponding to the presence information is transmitted to the target terminal device. Then, when there is a response to the emergency notification from the target terminal device, the transmission of the emergency signal is terminated.

In order to perform such an emergency notification service, the following functions are provided in the carrier center 100.
FIG. 3 is a block diagram illustrating functions of the carrier center.

The carrier center 100 includes an emergency notification server 110, a presence server 120, and an SMS (short message service) server 130.
FIG. 4 is a diagram illustrating a hardware configuration example of the emergency notification server.

  The entire emergency notification server 110 is controlled by a CPU (Central Processing Unit) 101. A random access memory (RAM) 102, a hard disk drive (HDD) 103, a graphic processing device 104, an input interface 105, and a communication interface 106 are connected to the CPU 101 via a bus 107.

  The RAM 102 temporarily stores at least part of an OS (Operating System) program and application programs to be executed by the CPU 101. The RAM 102 stores various data necessary for processing by the CPU 101. The HDD 103 stores an OS and application programs. A program file is stored in the HDD 103.

  A monitor 11 is connected to the graphic processing device 104. The graphic processing device 104 displays an image on the screen of the monitor 11 in accordance with a command from the CPU 101. A keyboard 12 and a mouse 13 are connected to the input interface 105. The input interface 105 transmits a signal transmitted from the keyboard 12 or the mouse 13 to the CPU 101 via the bus 107.

  The communication interface 106 is connected to the mobile terminal carrier network 10, the public telephone network 20, and the Internet 30. The communication interface 106 transmits / receives data to / from the mobile terminal devices 21, 22, and 23 via the mobile terminal carrier network 10. Data is transmitted to and received from the push-type telephone 31 via the public telephone network 20. Data is transmitted and received between the PC 41 and the mobile terminal device 51 via the Internet 30.

  With the hardware configuration as described above, the processing functions of the present embodiment can be realized. Although FIG. 4 shows the hardware configuration of the emergency notification server 110, the presence server 120 and the SMS server 130 can also be realized with the same hardware configuration.

Returning to FIG. 3, the description will be continued.
The emergency notification server 110 is a server that controls the entire emergency notification service. The emergency notification server 110 includes a pattern information table 111, a light emission information table 112, a terminal characteristic information table 113, a response information table 114, and an emergency notification management table 115, which will be described later, as information for determining an alert pattern. I have. Each of these tables is stored in the pattern information DB (database) 111a, the light emission information DB 112a, the terminal characteristic information DB 113a, the response information DB 114a, and the emergency notification management DB 115a, respectively.

  Upon receiving an emergency notification request from the caller terminal device 2, the emergency notification server 110 requests presence information of the user holding the target terminal device from the presence server 120. When the presence information of the user holding the target terminal device is received, alert pattern information that determines the action of the target terminal device according to the received presence information and the urgency level, and the target terminal device has its own presence information. A first notification request including response information regarding a response method to be executed in response to the request is transmitted to the presence server 120.

  When the emergency notification server 110 receives the updated presence information indicating that the presence information has been updated from the presence server 120 after the first notification request is transmitted, new alert pattern information and a response method are received based on the updated presence information. And a second notification request is transmitted to the presence server 120.

When the emergency notification server 110 receives the response confirmation information from the target terminal device from the presence server 120, the emergency notification server 110 cancels the request for presence information to the presence server 120.
The presence server 120 is a server that manages presence information used for the emergency notification service. It is assumed that the information regarding the target terminal device and the user holding the target terminal device is stored in a state where the presence server 120 can be used as a presence information table described later. This presence information table is stored in the presence information DB 121a included in the presence server 120.

  When the presence server 120 receives the notification request from the emergency notification server 110, the presence server 120 converts the notification request into a signal transmission request corresponding to the SMS server 130 and transmits the request to the SMS server 130.

  Further, every time the presence server 120 receives a presence information update request indicating that the presence of the target terminal device has changed from the target terminal device, the presence server 120 uses this target terminal device in the managed presence information table. After the presence information data corresponding to the user is updated and the first notification request is received from the emergency notification server 110, the updated presence information is further transmitted to the emergency notification server 110.

  When the presence server 120 receives a response confirmation request from the target terminal device, the presence server 120 updates the confirmation information corresponding to the user using the target terminal device in the managed presence information table, and also confirms the response. Information is transmitted to the emergency notification server 110.

  When the SMS server 130 receives a signal transmission request from the presence server 120, the SMS server 130 transmits an emergency signal enclosed in a short message to the target terminal device. At this time, if the target terminal device does not exist in the communicable range, it transmits as soon as communication becomes possible.

Next, functions of the mobile terminal devices 21, 22, and 23 will be described.
FIG. 5 is a block diagram illustrating the mobile terminal device.
Since the mobile terminal devices 21, 22, and 23 have the same functions, the mobile terminal device 21 will be described as a representative.

The mobile terminal device 21 includes an emergency notification signal reception unit 211, a position detection unit 212, a state switching unit 213, an emergency notification control unit 214, and an alert control unit 215.
The emergency notification signal reception unit 211 configures an interface that receives a short message sent from the SMS server 130, and transmits the received short message to the emergency notification control unit 214.

  The position detection unit 212 includes a GPS (Global Positioning System) function for detecting the position of the mobile terminal device 21 and a wireless LAN connection function, and the current position is within a predetermined area (for example, a building where the receiver works). Position detection information, such as whether it is outside the predetermined area or not, is transmitted to the emergency notification control unit 214.

  The state switching unit 213 has an operation unit (not shown) configured with a touch panel, buttons, and the like to switch the user's state (presence). When the user operates the operation unit, for example, “Busy” indicating that a specific task such as a meeting is being performed, and “Free” indicating that a specific task is not being performed such as at lunch These two modes can be switched. The state switching unit 213 transmits a presence update signal to the emergency notification control unit 214 using the operation of the operation unit as a trigger.

  When receiving the short message, the emergency notification control unit 214 transmits alert pattern information included in the emergency signal to the alert control unit 215. Further, upon receiving the position detection information, the emergency notification control unit 214 sends a presence information update request including position information to the presence server 120 when the presence of the item set in the presence information table described later changes. Send. When the presence of an item not set in the presence information table changes, a presence information update request including position information is transmitted to the presence server 120 at predetermined time intervals (for example, periodically). Further, upon receiving the presence update signal from the state switching unit 213, the emergency notification control unit 214 transmits a presence information update request including “Free” or “Busy” to the presence server 120. Further, the emergency notification control unit 214 stores an emergency signal incoming history when receiving an emergency signal.

  The alert control unit 215 includes a voice output unit such as a speaker, a light emitting unit such as an LED, and a vibration unit such as a vibrator. The alert control unit 215 outputs an alert using a unit corresponding to the alert pattern information and sends a short message to the user. Is received.

  As a result of the notification, the emergency notification control unit 214 receives a response confirmation by an operation (response operation) such as pressing a confirmation button (not shown) of the target terminal device by the receiver, and requests a response confirmation from the presence server 120 Send.

Next, the operation of the communication management system 500 according to the first embodiment will be described.
Below, the case where the push type telephone 31 performs emergency notification to the portable terminal device 21 typically is demonstrated.

FIG. 6 is a sequence diagram illustrating an operation of the communication management system according to the first embodiment.
First, the push-type telephone 31 transmits an emergency notification request to the emergency notification server 110 (step S11). Next, when the emergency notification server 110 receives the emergency notification request, the presence notification server 120 receives the target terminal device (in this case, the mobile terminal device 21) or information for specifying the user included in the emergency notification request. The presence information of the user holding the portable terminal device 21 is requested (step S12). Next, the presence server 120 transmits the presence information of the user holding the mobile terminal device 21 to the emergency notification server 110 (step S13). Then, the emergency notification server 110 creates a first notification request based on the emergency notification request and the presence information and transmits it to the presence server 120 (step S14). When the presence server 120 receives the first notification request, it generates a first signal transmission request and sends it to the SMS server 130 (step S15). Upon receiving the first signal transmission request, the SMS server 130 transmits the first emergency signal to the mobile terminal device 21 (step S16). When the mobile terminal device 21 receives the first emergency signal, an alert is output to notify the user.

  The mobile terminal device 21 transmits a presence information update request to the presence server 120 at a predetermined interval in accordance with the change in presence described above (step S17). The presence server 120 updates and manages presence information in response to receiving a presence information update request. When the presence server 120 receives a presence information update request from the mobile terminal device 21 when the user is unaware of the notification regarding the first emergency signal and the response operation is not executed, the presence server 120 updates the presence information and updates the presence information. Presence information is created and transmitted to the emergency notification server 110 (step S18).

  Then, the emergency notification server 110 creates a second notification request based on the updated presence information and transmits it to the presence server 120 (step S19). When the presence server 120 receives the second notification request, the second signal transmission request is transmitted to the SMS server 130 (step S20). When the SMS server 130 receives the second signal transmission request, the second emergency transmission request is transmitted. A signal is transmitted to the portable terminal device 21 (step S21).

  Here, when a response operation is executed by the user who notices the notification, the mobile terminal device 21 transmits a response confirmation request to the presence server 120 (step S22). When the presence server 120 receives the response confirmation request, it transmits response confirmation information including information for specifying at least the user or the target terminal device that has accepted the response to the emergency notification server 110 (step S23). When the emergency notification server 110 receives the response confirmation information, the request for presence information to the presence server 120 related to the user indicated in the response confirmation information is canceled (step S24).

This completes the operation of the communication management system.
Note that if the response operation is not executed by the user in step S21, the operations in steps S17 to S21 are repeatedly executed. In addition, based on the information regarding the response method included in the received emergency signal, the user who executed the response operation in step S22 takes a response such as actually making a call.

According to the present invention, the above-described processing makes it possible to retransmit the emergency notification to the other party that has not received a response to the emergency notification in accordance with the change in the other party's situation (presence).
Next, presence information, alert pattern information, and response information will be described in detail.

First, presence information will be described. The presence server 120 stores presence information as a table.
FIG. 7 is a diagram showing presence information.

  The presence information table 121 includes columns for user, portable terminal device, time, position / state, confirmation, and terminal characteristics, and information arranged in the horizontal direction of each column is associated with each other. The information stored in the presence information table 121 is not limited to this example. For example, information for identifying an emergency notification transmitted to the user may be registered as information associated with the other.

  Information for uniquely identifying a user holding each of the mobile terminal devices 21 to 23 is set in the user column. In FIG. 7, user A, user B, and user C are set. In the column of the mobile terminal device, for example, a unique ID is set as information for uniquely identifying the mobile terminal device used by these users. In FIG. 7, “# 1” that identifies the mobile terminal device 21 is set, “# 2” that identifies the mobile terminal device 22 is set, and “# 3” that identifies the mobile terminal device 23 is set. . Each working time of the user A, the user B, and the user C is set in the column within time. In FIG. 7, 9:00 to 18:00 is set as the working time of the user A. In addition, it is outside working hours except for the time set in the column for hours.

  In the position / state column, the current position and state are set as presence information of the user holding the portable terminal devices 21 to 23. In the position column, for example, “indoor” indicating that the user holding the mobile terminal devices 21 to 23 is in the building, “outdoor” indicating that the user is outside the building, and “indoor” and “outdoor” that cannot be identified. One of “Unknown” is set. Also, the states “Busy” and “Free” set by the state switching unit 213 of the mobile terminal devices 21 to 23 are set in the state column. In FIG. 7, “indoor / Busy” is set as the position / state of the user A. When the presence server 120 receives the presence information update request from the target terminal device, the presence server 120 receives the data in the “position / state” column associated with the corresponding user in the presence information table 121 based on the received content, and after the update. The presence information is updated, and updated presence information related to the updated presence information is transmitted to the emergency notification server 110 as necessary.

  In the confirmation column, a flag indicating whether or not a response confirmation request has been received from this user is set. “1” is set when a response confirmation request is not received, and “0” is set when a response confirmation request is confirmed. When the presence server 120 receives a response confirmation request from the target terminal device, the presence server 120 updates the data in the confirmation column associated with the corresponding user in the presence information table 121 to “0”, and further sends the response confirmation information to the emergency notification server. 110. In the example of user A in FIG. 7, “1” is set, indicating that a response confirmation request has not been received from user A yet.

  In the terminal characteristic column, a characteristic name indicating a terminal characteristic unique to the mobile terminal device is set. In FIG. 7, “default” is set as the terminal characteristic. The terminal characteristics will be described later.

Next, alert pattern information will be described.
The alert pattern information is created by pattern information and terminal characteristic information.
First, pattern information will be described.

In the emergency notification server 110, the pattern information is stored as a table.
FIG. 8 is a diagram showing a pattern information table.
The heading in the horizontal direction of the pattern information table 111 includes columns of urgency (low), urgency (medium), and urgency (high) corresponding to the urgency of the notification message specified by the caller. The vertical heading includes columns for time, out of time, and difficult to receive, for identifying the time and state corresponding to the presence information of the destination user. In the time column, there are further Free and Busy columns.

  The emergency notification server 110 extracts urgency information from the emergency notification request transmitted from the caller terminal device 2, and receives the information on the user's presence information included in the presence information received from the presence server 120 within the time and time. In addition, information on any of the incoming and outgoing difficulties is taken out, and a pattern of a portion where they match on the pattern information table 111 is taken out as pattern information. Here, pattern 1 in FIG. 8 is a pattern that causes the target terminal device to vibrate and blink the LED, pattern 2 is a pattern that generates a predetermined volume in addition to pattern 1, and pattern 3 is In addition to pattern 1, this is a pattern that generates the maximum volume. These patterns are separately managed by the profile and can be freely changed.

  In this example, in the case of urgency (high), the pattern 3 is set regardless of the state of the target terminal device. Thereby, it is possible to reliably notify the user of the incoming message. In the case of urgency (medium), pattern 3 is set when the target terminal device is “Free”, pattern 2 is set when “Busy”, and pattern 1 is set otherwise. Yes. In the case of urgency (low), pattern 3 is set only when the target terminal device is “Free”, and pattern 1 is set otherwise. For example, in the “Busy” state, which is assumed to be during a meeting, if the notification is urgent (low), it will vibrate and emit light without sounding so as not to bother other conference participants. In some cases, it is desirable to notify the user of the incoming call only. According to the pattern information table shown in FIG. 8, it is possible to set a way of ringing in consideration of such a user situation and surrounding environment.

Next, terminal characteristic information will be described. First, light emission information will be described.
In the emergency notification server 110, light emission information, which is information on the light emission color of the LED, is stored in a table.

FIG. 9 is a diagram showing a light emission information table.
In the light emission information table 112, columns of unknown, indoor, and outdoor corresponding to the location (position) of the target terminal device are provided in the horizontal direction, and columns of day and night corresponding to time are provided in the vertical direction. It has been. In FIG. 9, “blue” (cold) is set when the location is unknown, “red” is set when the location is indoors, and “red” is set at noon when the location is outdoors. “Yellow” (warm) is set at night. As a situation around the target terminal device, it may be considered that the user terminal may be easily recognized by the light emitted from the target terminal device during daytime and night, and indoors and outdoors. According to the light emission information table shown in FIG. 9, since it is possible to set how to emit light in consideration of such surrounding conditions, it is possible to reliably notify the user of an incoming call. Note that, in the light emission information table 112, only color information is set, but information of various light emission patterns may be set. The distinction between day and night may be specified by the user, or may be automatically set by another method of the emergency notification server 110.

  The emergency notification server 110 extracts location information from the presence information of the user included in the presence information received from the presence server 120, and determines the emission color of the portion where the location information and the separately acquired current time information match. Extracted from the light emission information table 112 as light emission information.

In the emergency notification server 110, the terminal characteristic information is stored as a table.
FIG. 10 is a diagram illustrating a terminal characteristic information table.
The terminal characteristic information table 113 is provided with columns of characteristic, sound, light emission, and vibration, and information arranged in the horizontal direction of each column is associated with each other.

A name for identifying the terminal characteristic of the target terminal device is set in the characteristic column. In FIG. 10, “default”, “silence”, and “prohibit light emission” are set.
The sound, light emission, and vibrate columns are set corresponding to the notification means of the alert control unit 215 of the mobile terminal devices 21 to 23. “O” is set for the means that can be used by the mobile terminal devices 21 to 23, and “X” is set for the functions that cannot be used or are not used. The information set in the terminal characteristic information table 113 includes, for example, when the user who uses the target terminal device has a hearing impairment, “silence” as the presence information of the user, This can be used to set “flash prohibition”.

Next, the response information will be described.
In the emergency notification server 110, the response information is stored as a table.
FIG. 11 is a diagram showing a response information table.

  In the present invention, the emergency signal notifies the user that it is necessary to contact urgently or only an outline of the emergency situation, and responds to the emergency signal for specific contents of the emergency situation and specific instruction contents. It is assumed that the user accesses the predetermined contact information according to the method shown in the response method and obtains information.

  The response information table 114 includes telephone, message distribution, and application distribution fields as a method of notifying the user who responded to the emergency notification (emergency signal transmitted from the SMS server 130) in the horizontal direction as a specific content of emergency information. In the vertical direction, the status of the target terminal device that has received the emergency notification is provided with a column indicating that communication is possible and difficult to call, and information on the response method from the target terminal device for the transmitted emergency notification is managed. is doing.

  Call allowed indicates a state in which a call can be made when the recipient responds to the alert. Call difficulty indicates a case where a call is difficult when a recipient responds to an alert.

Actions desired by the caller when the receiver responds to the alert are set in the fields of telephone, message distribution, and application distribution.
For example, if the caller wants a telephone call back from the receiver, or if the caller is able to talk, an action that causes the caller to make a call (for example, connect a reply telephone call from the receiver to the caller) ) Is set. It is also possible to set an action for making a call to the number set in the presence information message column.

  This response information table 114 can be freely rewritten, for example, by an administrator of the carrier center 100 or the like. According to the response information table 114 shown in FIG. 11, it is possible to notify the target terminal device used by the receiver by including the response method desired by the sender to the receiver in the emergency signal.

  FIG. 12 is a diagram illustrating an emergency notification management table. The emergency notification server 110 includes an emergency notification management table 115 as a data table for managing the emergency notifications received from the caller terminal device 2. In the emergency notification management table 115, for each emergency notification request received from the caller terminal device 2, “caller” that is information for identifying the caller and information indicating the number of respondents who want to respond among the receivers. A certain number of “responses”, “content” that is information indicating the storage location of the notification content data, “recipient” that is information for identifying the receiver that is the destination of the emergency notification, and this “Presence”, which is presence information of the receiver, and “confirmation”, which is a flag indicating whether or not a response confirmation has been received from the receiver, are held in association with each other.

  Upon receiving the user presence information (or updated presence information) from the presence server 120, the emergency notification server 110 updates the data in the “presence” column of the corresponding user with the received data. Further, when response confirmation information from the target terminal device is received from the presence server 120, the data in the “confirmation” column of the corresponding user is updated from “1” indicating non-reception to “0” indicating reception.

The emergency notification management table 115 is deleted when it is no longer necessary to transmit the emergency notification shown in the table.
According to the emergency notification management table 115 shown in FIG. 12, the emergency notification server 110 manages, for each emergency notification, information on the user to be transmitted, presence information on the user, and whether or not there is a response from the user. Is possible.

Next, notification request transmission processing in the emergency notification server 110 will be described with reference to a flowchart.
FIG. 13 is a flowchart showing notification request transmission processing.

First, presence information of a user who is a communication partner is received from the presence server 120 (step S31).
Next, based on the received presence information, the pattern information table 111 and the terminal characteristic information table 113 are referred to perform a logical sum (AND) to determine alert pattern information to be transmitted to the target terminal device (step S32). Next, it is determined whether or not the target terminal device can use the light emitting function, that is, whether or not the terminal characteristic of the presence information is “default” or “silence” (step S33). When the target terminal device cannot use the light emitting function (when “light emission prohibition” is set in the terminal characteristics) (No in step S33), the process proceeds to step S35. On the other hand, when the target terminal device can use the light emission function (Yes in step S33), the light emission information is determined with reference to the light emission information table 112, and this information is added to the alert pattern information (step S34). Then, a notification request including alert pattern information and response information is determined (step S35). This notification request is transmitted to the presence server 120 (step S36).

This completes the notification request transmission process.
As described above, according to the communication management system 500, when the emergency notification server 110 receives an emergency notification request, it transmits a notification request according to the presence information update request of the target terminal device to the target terminal device. On the other hand, communication resources can be effectively utilized by efficiently retransmitting emergency signals.

  In particular, when the “Not busy” is changed to “Free” as the trigger for transmitting the presence information update request received by the emergency notification server 110, or when “Not in time” is changed to “In time”, these timings are used. It is likely that the recipient has a high probability of operating the mobile terminal device for any purpose, such as checking the incoming history of the mobile terminal device, checking the transmission / reception of e-mails or short messages, or making a call. By selecting the situation and setting these in the presence information table 121 in advance, a presence update request can be transmitted to the presence server 120 in an environment that is easily noticed by the user, so notification to the recipient of the target terminal device Can be performed more reliably.

  Further, the trigger for transmitting the presence information update request is not limited to the one described above. For example, when the power of the receiver's mobile terminal device is switched from OFF to ON, or a call is made from the receiver's mobile terminal device. It is also possible to trigger when an e-mail or a short message is sent. In this case, these are set in the presence information table 121 so as to trigger the presence information update request transmission, and the emergency notification control unit 214 is configured to transmit the presence information update request as in the above-described embodiment. The effect is obtained.

  Further, unlike the case where the emergency signal is simply retransmitted, the presence of the receiver has changed, for example, when the receiver holding the target terminal device moves from the room to the outdoors or the mode is changed from “Busy” to “Free”. Since it can be set in advance in the pattern information table 111 so as to switch to a pattern with a high notification effect and execute notification when triggered by the emergency notification server 110, The pattern information corresponding to the presence information can be selected and retransmitted, so that notification to the recipient of the target terminal device can be performed more reliably.

  Further, in the case of a meeting or the like, it is possible to perform notification in consideration of the recipient and the surrounding environment. In this way, it is possible to realize the transmission of an emergency signal to a receiver according to TPO (Time Place Occasion).

  In addition, by including response information in the notification request, it is possible to execute different responses depending on whether the receiver is able to make a call or if the call is difficult. A desired response can be easily executed.

Next, a communication management system according to the second embodiment will be described.
Hereinafter, the communication management system 500 according to the second embodiment will be described with a focus on differences from the first embodiment described above, and descriptions of similar matters will be omitted.

  In the communication management system 500 according to the second embodiment, there are a plurality of emergency notification destinations, that is, the emergency notification server 110 transmits an emergency signal to all the mobile terminal devices 21 to 23 by the terminal device of the caller. The point is different from the communication management system of the first embodiment, and the other points are the same as those of the first embodiment.

Next, the operation of the communication management system according to the second embodiment will be described.
Below, the case where the push-type telephone 31 transmits an emergency notification request to the portable terminal devices 21 and 22 typically is demonstrated.

FIG. 14 is a sequence diagram illustrating an operation of the communication management system according to the second embodiment.
First, the push-type telephone 31 transmits each emergency notification request to the mobile terminal devices 21 and 22 (step S41).

  Next, when the emergency notification server 110 receives the emergency notification request, the presence server 120 requests the presence information of each of the mobile terminal devices 21 and 22 (step S42). Next, the presence server 120 transmits the presence information of the mobile terminal devices 21 and 22 to the emergency notification server 110 (step S43). Then, the emergency notification server 110 creates a third notification request based on the emergency notification request and the presence information of the mobile terminal device 21, and transmits it to the presence server 120 (step S44). Further, a fourth notification request is created based on the emergency notification request and the presence information of the mobile terminal device 22, and is transmitted to the presence server 120 (step S45).

  When the presence server 120 receives the third notification request, the presence server 120 transmits a third signal transmission request for the portable terminal device 21 to the SMS server 130 (step S46). When the presence server 120 receives the fourth notification request, the presence server 120 transmits a fourth signal transmission request directed to the mobile terminal device 22 to the SMS server 130 (step S47). When the SMS server 130 receives the third signal transmission request, the SMS server 130 transmits a third emergency signal to the mobile terminal device 21 (step S48). In addition, when the fourth signal transmission request is received, a fourth emergency signal is transmitted to the portable terminal device 22 (step S49).

  When the mobile terminal device 21 receives the third emergency signal, an alert indicated by the emergency signal is output to notify the user. When the mobile terminal device 22 receives the fourth emergency signal, an alert indicated by the emergency signal is output to notify the user.

  Here, when a response operation is executed by the user of the mobile terminal device 21 who notices the notification, the mobile terminal device 21 transmits a response confirmation request to the presence server 120 (step S50). When the presence server 120 receives the response confirmation request, the response confirmation information is transmitted to the emergency notification server 110 (step S51). When the emergency notification server 110 receives the response confirmation information, the presence information request to the presence server 120 is canceled (step S52).

  In addition, after step S49, when the user of the mobile terminal device 22 is not aware of the notification and the response operation is not executed, the mobile terminal device 22 transmits a presence information update request according to the presence change to the emergency notification server 110. (Step S53). When the presence server 120 receives the presence information update request, it updates the presence information, creates updated presence information, and transmits it to the emergency notification server 110 (step S54).

  Then, the emergency notification server 110 creates a fifth notification request based on the updated presence information and transmits it to the presence server 120 (step S55). When the presence server 120 receives the fifth notification request, it transmits a fifth signal transmission request to the SMS server 130 (step S56). When the SMS server 130 receives the fifth signal transmission request, the SMS server 130 transmits a fifth emergency signal to the target terminal device (step S57).

Here, when a response operation is executed by the user of the mobile terminal device 22 that has noticed the notification, the same operations as steps S50 to S52 are executed (steps S58 to S60).
The operation of the communication management system according to the second embodiment is thus completed.

According to the communication management system 500 of the second embodiment, the same effect as that of the communication management system 500 of the first embodiment can be obtained.
According to the communication management system 500 of the second embodiment, the emergency notification server 110 acquires presence information corresponding to each target terminal device from the presence server 120, and sends a notification request to each target terminal device. Since the transmission is performed, the emergency signal can be transmitted to each of the plurality of target terminal devices. In addition, since the target terminal device can be designated, communication resources can be used more effectively than when emergency signals are transmitted to all mobile terminal devices.

Next, a communication management system according to the third embodiment will be described.
Hereinafter, the communication management system 500 according to the third embodiment will be described with a focus on differences from the second embodiment described above, and description of similar matters will be omitted.

  In the communication management system according to the third embodiment, the sender sets in advance the number of target terminal devices (hereinafter referred to as “desired response number”) that he / she wants to respond to among the parties to whom an emergency notification is made, When the number of responding target terminal devices reaches the desired number of responses, the carrier center 100 transmits a notification history deletion request for deleting the emergency signal incoming history of the target terminal device to the non-response target terminal device. The communication management system is different from the communication management system of the second embodiment, and other than that is the same as the second embodiment.

Next, the operation of the communication management system 500 according to the third embodiment will be described.
A case will be described below in which the push-type telephone 31 typically performs broadcast notification to the mobile terminal devices 21 to 23 and the desired number of responses is 1.

FIG. 15 is a sequence diagram illustrating an operation of the communication management system according to the third embodiment.
First, the push-type telephone 31 transmits each emergency notification request of 21 to 23 to the mobile terminal device (step S61).

  Next, when the emergency notification server 110 receives the emergency notification request, the request for the presence information of each of the users holding the portable terminal devices 21 to 23 in the presence server 120 based on the information specifying the user included in the emergency notification request. Is performed (step S62). Next, the presence server 120 transmits the presence information of the users holding the mobile terminal devices 21 to 23 to the emergency notification server 110 (step S63). Then, the emergency notification server 110 creates sixth to eighth notification requests based on the emergency notification request and presence information, and transmits them to the presence server 120 (steps S64 to S66).

  When the presence server 120 receives the sixth notification request, it transmits a sixth signal transmission request for the portable terminal device 21 to the SMS server 130 (step S67). When the presence server 120 receives the seventh notification request, the presence server 120 transmits a seventh signal transmission request directed to the mobile terminal device 22 to the SMS server 130 (step S68). When the presence server 120 receives the eighth notification request, it transmits an eighth signal transmission request for the portable terminal device 23 to the SMS server 130 (step S69).

  When the SMS server 130 receives the sixth signal transmission request, the SMS server 130 transmits a sixth emergency signal to the mobile terminal device 21 (step S70). When the seventh signal transmission request is received, a seventh emergency signal is transmitted to the mobile terminal device 22 (step S71). When the eighth signal transmission request is received, an eighth emergency signal is transmitted to the target terminal device 23 (step S72).

  And the portable terminal device 21 will alert | report to a user by outputting the alert shown by an emergency signal, if a 6th emergency signal is received. When receiving the seventh emergency signal, the mobile terminal device 22 outputs an alert indicated by the emergency signal to notify the user. When receiving the eighth emergency signal, the mobile terminal device 23 outputs an alert indicated by the emergency signal to notify the user. And when the user of the portable terminal devices 21-23 does not notice notification, re-notification is performed about the portable terminal devices 21-23 similarly to 1st Embodiment.

  Here, when a response operation is executed by the user of the mobile terminal device 21 who notices the notification, the mobile terminal device 21 transmits a response confirmation request to the presence server 120 (step S73). When the presence server 120 receives the response confirmation request, the response confirmation information is transmitted to the emergency notification server 110 (step S74).

  When the emergency notification server 110 receives the response confirmation information, the emergency notification server 110 determines whether or not the number of received response confirmation information (cumulative number) matches the desired number of responses for the emergency notification related to the response confirmation information. . Then, if the number of received response confirmation information matches the desired number of responses, the presence server 120 cancels the request for presence information regarding the user who is the destination of the emergency notification (step S75), and the emergency notification server 110 transmits to the presence server 120 a first notification history erasure request for erasing the emergency signal incoming history of the mobile terminal device 22, which is a terminal that has not yet received the response confirmation information for this emergency notification (step S76). Similarly, a second notification history deletion request for deleting the emergency signal incoming history of the mobile terminal device 23 is transmitted (step S77).

  When the presence server receives the first notification history erasure request, it transmits a first history erasure signal transmission request to the SMS server 130 (step S78). When the presence server 120 receives the second notification history deletion request, the presence server 120 transmits a second history deletion signal transmission request to the SMS server 130 (step S79).

  When the SMS server 130 receives the first history erasure signal transmission request, the SMS server 130 transmits the history erasure signal to the mobile terminal device 22 (step S80). Thereby, the emergency signal incoming history related to the emergency notification of the mobile terminal device 22 is deleted. Similarly, when the second history erasure signal transmission request is received, the history erasure signal is transmitted to the portable terminal device 23 (step S81). Thereby, the emergency signal transmission history of the portable terminal device 23 is deleted.

The operation of the communication management system 500 according to the third embodiment is thus completed.
According to the communication management system 500 of the third embodiment, the same effect as that of the communication management system 500 of the first embodiment can be obtained.

  In addition, according to the communication management system 500 of the third embodiment, for example, if any three of a person-in-charge group composed of 10 people respond to a case that requires urgent action, If it is good, all 10 people will be sent as emergency notifications, and when they receive a response confirmation from the number of respondents who want to respond, they will stop resending emergency notifications to the remaining 7 people Since a communication method can be realized, it is possible to suppress communication to a partner that no longer needs to send an emergency notification, and to suppress wasteful consumption of communication resources.

  According to the communication management system 500 of the third embodiment, the emergency signal incoming history of the target terminal device that no longer needs to send a response confirmation request is deleted, thereby referring to the incoming history. It is possible to suppress useless callback from the user and to suppress useless consumption of communication resources.

  In the present embodiment, the emergency notification server 110 has been described as transmitting a notification history deletion request when there is a response from one of the three mobile terminal devices 21, 22, and 23. The number is not limited to this, and it goes without saying that an emergency history deletion request can be transmitted in the same manner when there is a response from two (a plurality of) target terminal devices.

  Moreover, in this Embodiment, it is preferable that the emergency notification server 110 is comprised so that the information of the target terminal device which transmitted the response confirmation request may be recorded. Thereby, it can be easily confirmed from which target terminal device the response confirmation request is transmitted.

Next, operations of the emergency notification server 110 in the first to third embodiments will be described together.
16 to 18 are flowcharts showing the operation of the emergency notification server in the first to third embodiments.

  First, when an emergency notification request is received, it is determined whether or not the emergency notification request is a request for a plurality of portable terminal devices (step S91). When the emergency notification request is not a request for a plurality of portable terminal devices (No in step S91) (corresponding to the first embodiment), the presence information of the target terminal device is requested (step S92). Next, a notification request is transmitted to the presence server 120 (step S93).

  Next, it is determined whether or not response confirmation information has been received from the presence server 120 (step S94). That is, it is confirmed whether or not the data in the “confirmation” column corresponding to this user is “0” in the emergency notification management table 115. If the data in the “confirmation” column is “1” and no response confirmation information has been received (No in step S94), it is determined whether or not updated presence information has been received from the presence server 120 (step S95). When the updated presence information is received (Yes in step S95), the process proceeds to step S93 based on the updated presence information indicated in the updated presence information corresponding to the user in the emergency notification management table 115, and a new notification request is made. Send. If the updated presence information has not been received (No in step S95), the process proceeds to step S94 and the operation is continued. On the other hand, when response confirmation information is received (Yes in step S94), the request for presence information of the target terminal device is canceled (step S96), and the operation is terminated.

  If the emergency notification request is a request for a plurality of portable terminal devices in step S91 (Yes in step S91) (corresponding to the second and third embodiments), the process proceeds to the process shown in FIG. Presence information is requested for the number of target terminal devices (step S97).

  Next, it is determined whether or not the number of target terminal devices matches the desired number of responses (step S98). When the number of target terminal devices matches the desired number of responses (Yes in step S98) (corresponding to the second embodiment), the mobile terminal devices 21 to 23 perform the same operations as steps S93 to S96, respectively ( Steps S99 to S102).

  When response confirmation information is received for one mobile terminal device among the target terminal devices (step S100), when the request for presence information is canceled (step S102), the emergency notification management table 115 is set for the emergency notification to be transmitted. It is determined whether or not response confirmation information has been received for all target terminal devices, that is, whether or not the data in the “confirmation” column is “0” (step S103). If the response confirmation information has not been received for all the target terminal devices, that is, if there is data whose data in the “confirmation” column is “1” (No in step S103), the process proceeds to step S100 and the operation is continued. . On the other hand, when the response confirmation information is received for all the target terminal devices (Yes in step S103), the operation ends.

  In step S98, if the number of target terminal devices does not match the desired response number (No in step S98) (corresponding to the third embodiment), the process proceeds to the process shown in FIG. Operations similar to those in steps S99 to S102 are performed for the target terminal device (steps S104 to S107). When the request for presence information is canceled for one portable terminal device among the target terminal devices in step S107, the emergency notification management table 115 is referred to for the emergency notification to be transmitted, and the total number of response confirmation information received, that is, Then, it is determined whether or not the number of users whose data in the “confirmation” column is “0” in the data related to the relevant emergency notification in the emergency notification management table 115 matches the desired response number (step S108). If the number of received response confirmation information does not match the desired number of responses (No in step S108), the process proceeds to step S105 and the operation is continued.

  On the other hand, if the number of received response confirmation information matches the desired number of responses (Yes in step S108), the target terminal device that has not transmitted the response confirmation request, that is, the data on the relevant emergency notification in the emergency notification management table 115 is stored. Among them, the notification history deletion request is transmitted to the target terminal device associated with the user whose data in the “confirmation” column is “1” (step S109), and all the response confirmation requests have not been transmitted. The request to the presence server 120 for the presence information of the target terminal device is canceled (step S110), and the operation is terminated.

Although the preferred embodiment of the present invention has been described in detail above, the present invention is not limited to the specific embodiment.
