Description

  The present invention relates to an emergency notification system, a mobile communication terminal, and an emergency notification method, and more particularly, to an emergency notification system, a mobile communication terminal, and an emergency notification method for notifying a third party of emergency notification information transmitted by a rescue requester.

  A system that can notify a third party of an emergency using a mobile communication terminal when you suddenly fall out of physical condition while you are out or when you want to call for help immediately, such as an accident, fire, or crime. Mobile terminal devices have been proposed.

  For example, Patent Literature 1 discloses an emergency call system in which a base station transfers an emergency message transmitted from a calling terminal that is a mobile communication terminal to a management server and a called terminal.

  The calling terminal generates and transmits a first emergency message and a second emergency message. The first emergency message includes an emergency call message, a telephone number (reception destination list) of at least one called terminal, and base station identification information. The second emergency message includes the emergency call message and the telephone number of the calling terminal.

  The base station receives these first and second emergency messages, forwards the received first emergency message to the management server, and the second emergency message is included in the recipient list of the first emergency message Transfer to the called terminal.

  When the management server recognizes an emergency situation of a subscriber registered in advance, the management server notifies the emergency reception center of the emergency situation.

  The user of the called terminal that has received the second emergency message attempts a voice call with the user of the calling terminal based on the telephone number of the calling terminal included in the second emergency message.

  Patent Document 2 discloses an emergency call notification system capable of promptly notifying an occurrence of an emergency to a user of a mobile terminal located near the mobile terminal that is the source of the emergency call.

  In the emergency call notification system disclosed in Patent Document 2, when a base station receives an emergency call by data communication from a mobile terminal in its service area, the emergency call is sent to the mobile terminal in its service area. Broadcast. At the same time, the adjacent base station is caused to broadcast the emergency call to mobile terminals in the service area of the base station.

  Further, Patent Document 3 discloses a mobile terminal device that can reliably notify an emergency call.

  When an emergency call operation is performed, the mobile terminal device disclosed in Patent Document 3 transmits an emergency call by long-distance wireless based on the emergency call information and the emergency call transmission destination information stored in the memory. On the other hand, a short-range radio is also provided, and emergency call information is transmitted to the surroundings by the short-range radio.

Special table 2008-544627 JP 2010-193234 A JP 2006-352697

  In the emergency call system disclosed in Patent Document 1, an emergency call message is transmitted to at least one called terminal specified by a destination list included in the first emergency message.

  In other words, this emergency call system transmits an emergency call message regardless of the positional relationship between a call terminal that is a rescue requester who encounters an emergency and a called terminal that is a rescuer. Therefore, when the rescuer who receives the emergency call message is far away, there is a problem that the rescue request cannot be immediately responded.

  In the emergency call notification system disclosed in Patent Document 2, an emergency call is broadcast to mobile terminals that exist in the same base station service area and adjacent base station service area as the mobile terminal that sent the emergency call.

  Since this emergency call notification system broadcasts an emergency call to an unspecified number of mobile terminals existing in the corresponding service area, an unnecessarily large number of people are involved. Therefore, as the period elapses from the introduction of this emergency call notification system, it seems that “someone will respond” and there is a concern that many people will become indifferent. That is, even if a broadcast emergency call is received, it may be left unattended.

  The mobile terminal device disclosed in Patent Literature 3 transmits an emergency call by a long-distance wireless based on the emergency call transmission destination information registered in advance, and further notifies the surroundings by a short-range wireless.

  Therefore, similarly to the emergency call system disclosed in Patent Document 1, when a rescuer who receives an emergency call is in the distance, there is a problem that a rescue request cannot be immediately responded. On the other hand, although the emergency call is configured to be notified to the surroundings by short-range wireless communication, it can be received only by a portable terminal device having the same type of short-range wireless function. Therefore, there is a problem of lacking versatility.

  In view of the above problems, an object of the present invention is to provide an emergency notification system, a portable communication terminal, and an emergency notification method for efficiently informing emergency rescue information to a rescuer according to the situation of a rescue requester who has encountered an emergency. It is to provide.

  DESCRIPTION OF EMBODIMENTS Embodiments for carrying out the present invention will be described with reference to the drawings. The embodiments are examples, and the disclosed system and apparatus are not limited to the configurations of the following embodiments.

(First embodiment)
An emergency notification system, a mobile communication terminal, an emergency notification method using an emergency notification system, and an emergency notification method using a mobile communication terminal according to a first embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a block diagram showing the configuration of the emergency notification system according to the first embodiment of the present invention.

  The emergency notification system 100 according to the first embodiment includes a mobile communication terminal 10-13 connected to the communication network 30 and an emergency notification server 20 connected to the communication network 30. The emergency notification system 100 distributes an emergency notification mail for notifying an emergency transmitted by the rescue requester to the mobile communication terminal of the user who has registered the service, and notifies the rescuer existing in the vicinity of the rescue requester of the emergency. Provide emergency alert service.

  The communication network 30 is a mobile communication network, and includes an access network including a base station (not shown) that connects the mobile communication terminals 10 to 13 through a wireless line, an exchange in the network, a router, a transmission facility, etc. (not shown). And a core network.

  The mobile communication terminals 10 to 13 are mobile phones having a function capable of acquiring the position information of the own terminal. For the position information of the terminal itself, in a mobile phone equipped with a global positioning system (GPS), latitude and longitude obtained based on GPS signals from positioning satellites are used. Further, in a base station configuration such as a micro cell or a femto cell in a mobile communication system, a geographical position in a relatively narrow range can be specified by identifying a base station area. Therefore, the present embodiment can also be applied to a mobile phone provided with information for associating the identified base station area with the geographical position information even if the GPS is not provided. Of course, it may be a terminal having a communication function and position information acquisition function equivalent to such a mobile phone, for example, a personal data assistant (PDA) or PC (Personal Computer).

  For example, the mobile communication terminal 10 is a mobile communication terminal (first mobile communication terminal) used by a user who has experienced an emergency. When the mobile communication terminal 10 detects an emergency operation, first, the mobile communication terminal 10 acquires the position information of the own terminal as the transmission side position information. Next, an emergency notification mail including predetermined information for notifying an emergency, a predetermined emergency notification destination mail address, and the acquired transmission side position information is generated. Then, the generated emergency notification mail is transmitted to the communication network 30.

  The emergency notification server 20 is connected to the communication network 30 and functions as a server that receives an emergency notification mail and distributes it. That is, the emergency notification mail transmitted by the first mobile communication terminal reaches the emergency notification server 20 based on the emergency notification destination mail address. The emergency notification server 20 may be directly connected to the communication network 30 or may be connected to the communication network 30 via another communication network (not shown).

  In the emergency notification server 20, a mail address of a mobile communication terminal (second mobile communication terminal) of a user who subscribes to the emergency notification service is registered in advance. For example, all of the mobile terminal devices 10 to 13 illustrated in FIG. 1 may be used as the second mobile communication terminal. Of course, all these mobile communication terminals have the above-described position information acquisition function. The mobile communication terminal of the user who subscribes to the emergency notification service may belong to any communication carrier as long as it is a terminal of a communication carrier that provides mail service by the mobile communication terminal.

  When the emergency notification server 20 receives the emergency notification mail, the emergency notification server 20 resets the pre-registered mail address of the second mobile communication terminal as the destination of the received emergency notification mail. Then, an emergency notification mail addressed to the mail address of the second mobile communication terminal is transmitted to the communication network 30.

  The mobile communication terminal that has identified and received the emergency notification mail from the communication network 30 acquires the position information of the terminal itself as the reception-side position information. Then, the distance between the reception side position and the transmission side position is calculated based on the acquired reception side position information and the transmission side position information included in the emergency notification mail.

  When the calculated distance is within the threshold, the mobile communication terminal (for example, the mobile communication terminal 11) corresponds to predetermined information for notifying an emergency situation included in the emergency notification mail as the third mobile communication terminal. A message is displayed and an emergency notification operation is performed.

  As described above, the emergency notification mail is received separately from the normal mail in the mobile communication terminal. That is, when receiving a normal mail, the mobile communication terminal immediately notifies the user that the mail has been received. However, when an emergency notification mail is received, it is received without notifying the user, a process for determining whether or not emergency notification is necessary, and when it is determined that emergency notification is necessary in the mobile communication terminal, Emergency notification to the user.

  With the above configuration, the emergency notification operation can be performed only for the third mobile communication terminal in the vicinity of the first mobile communication terminal that has requested rescue.

  FIG. 2 is a block diagram illustrating a configuration of the mobile communication terminal according to the first embodiment.

  The mobile communication terminal 10 according to the first embodiment includes a location information acquisition unit 110, an emergency notification mail generation unit 120, a mail transmission unit 130, a mail reception unit 140, and an emergency notification operation execution unit 150. In FIG. 2, illustration of functional configurations as normal mobile communication terminals such as a wireless transmission / reception unit, an input / output unit (operation unit), a storage unit, and a display unit is omitted.

  The location information acquisition unit 110 has a function of acquiring location information of the terminal itself.

  If it is a terminal provided with GPS, it has a function of calculating the latitude and longitude of its own terminal based on GPS signals from positioning satellites. The positioning method may be either a single positioning method or a relative positioning method. Further, if the terminal has a function of acquiring the position information of the terminal itself by identifying the base station area, the terminal has a database in which the base station area and the geographical position are associated with each other, and outputs the identified geographical position information. . The geographical position information may be managed as address information, for example, or may be managed as corresponding latitude / longitude information.

  When the emergency notification mail generation unit 120 detects an emergency operation performed by the user operating an input / output unit (not shown), the emergency notification mail generation unit 120 acquires the location information of the terminal itself from the location information acquisition unit 110 as transmission side location information. Then, the emergency notification mail generation means 120 generates and outputs an emergency notification mail including predetermined information for notifying an emergency, a predetermined emergency notification destination mail address, and transmission side position information.

  The predetermined information for notifying an emergency is a message code corresponding to an emergency notification message, which is determined in advance by the emergency notification service. The message code is determined according to the emergency level and type of emergency, and may be selected and set by the user, or it may be a default message code used when there is no room for selection. Good. The message code is set in a storage unit (not shown).

  Further, the predetermined emergency notification destination email address is the email address of the emergency notification server described with reference to FIG. 1 that executes the process of distributing the generated emergency notification mail. The emergency notification destination mail address is also set in advance in a storage unit (not shown).

  The mail transmission unit 130 transmits the emergency notification mail generated by the emergency notification mail generation unit 120 to the communication network. For example, the mail transmission unit 130 transmits a transmission control packet, and subsequently transmits the generated emergency notification mail data packet to the mail server of the communication carrier to which the user is subscribed. The emergency notification mail is transferred from the mail server of this communication carrier by SMTP (Simple Mail Transfer Protocol) based on the emergency notification destination mail address, and reaches the emergency notification server.

  The above is description of each function means for the portable communication terminal 10 to function as an emergency alert mail transmission side.

  On the other hand, the description of the functional means for the mobile communication terminal 10 to function as the emergency alert mail receiving side is as follows.

  The emergency notification mail distributed by the emergency notification server described above is transferred by SMTP based on the reset mail address and reaches the mail server of this mobile communication network. The mobile communication terminal is notified that the mail has arrived at the mail server of the mobile communication network, and the mail receiving means 140 identifies and receives the emergency notification mail.

  That is, when the mail receiving unit 140 receives a notification that the mail has arrived at the mail server and identifies that the mail type is an emergency notification mail, the mail reception unit 140 transmits a reception request to the mail server and receives the emergency notification mail. .

  In this case, it is assumed that the mail reception notification sent from the communication network to the mobile communication terminal is added with information that allows the mail receiving means 140 to identify that the mail type is an emergency notification mail. Then, the mail receiving means 140 that has identified that the received mail is an emergency notification mail performs an operation of fetching the incoming mail from the mail server without notifying the user of the incoming mail information.

  The mail receiving unit 140 that has received the emergency notification mail outputs the received emergency notification mail and the emergency notification operation execution necessity determination instruction information that instructs determination of whether or not the emergency notification operation is to be performed.

  When the emergency notification operation execution unit 150 receives the emergency notification mail and the emergency notification operation execution necessity determination instruction information from the mail reception unit 140, the emergency notification operation execution unit 150 first determines whether the emergency notification operation execution is necessary.

  The emergency notification operation execution means 150 acquires the position information of the terminal itself from the position information acquisition means 110 as reception-side position information. Further, the transmission side position information is extracted from the emergency notification mail. Then, the emergency notification operation executing means 150 calculates the distance between the reception side position (own terminal) and the transmission side position (rescue request terminal) based on the acquired reception side position information and the extracted transmission side position information. .

  When the calculated distance is within the threshold, the emergency notification operation execution unit 150 determines that the emergency notification operation is necessary, and does not illustrate a message corresponding to the predetermined information for notifying the emergency situation included in the emergency notification mail. An emergency notification operation is performed by displaying an alarm sound or the like on the display unit. At this time, the emergency notification operation execution unit 150 reads an emergency notification message corresponding to the emergency notification message code included in the emergency notification mail from a storage unit (not shown).

  With the above configuration, the emergency notification operation is performed only when the terminal is located in the vicinity of the mobile communication terminal that has requested rescue.

  FIG. 3 is a flowchart for explaining the operation of the emergency notification system according to the first embodiment.

  Processing is performed between the transmitting-side mobile communication terminal, the emergency notification server, and the receiving-side mobile communication terminal.

  First, in the mobile communication terminal on the transmission side, an emergency operation is detected when the user performs a key operation for starting an emergency notification (S110).

  When the emergency operation is detected, the transmission side mobile communication terminal acquires the position information of the own terminal as the transmission side position information (S111). Then, an emergency notification mail including predetermined information for notifying an emergency situation, a predetermined emergency notification destination mail address, and the acquired transmission side position information is generated (S112).

  The transmission-side mobile communication terminal transmits the generated emergency notification mail to the communication network (S113).

  The emergency notification server connected to the communication network receives the emergency notification mail (S120).

  The emergency notification server that has received the emergency notification mail performs editing to reset the registered mail address of the registered mobile communication terminal as the destination of the emergency notification mail (S121).

  The emergency notification server transmits an emergency notification mail whose destination is reset to the mail address of the registered mobile communication terminal to the communication network (S122).

  When the receiving side mobile communication terminal identifies and receives the emergency notification mail from the communication network (S130), the receiving side mobile communication terminal acquires the position information of the own terminal as the receiving side position information (S131). Further, the receiving-side mobile communication terminal extracts transmitting-side position information from the emergency notification mail (S132).

  Then, the reception-side mobile communication terminal calculates the distance between the reception-side position and the transmission-side position based on the acquired reception-side position information and the transmission-side position information extracted from the emergency notification mail (S133). The distance is compared with a threshold value (S134).

  When the calculated distance is within the threshold (S134, YES), the receiving-side mobile communication terminal displays a message corresponding to the predetermined information for notifying the emergency situation included in the emergency notification mail and performs the emergency notification operation. Perform (S135).

  If the calculated distance is not within the threshold (S134, NO), the receiving mobile communication terminal ends the process without doing anything.

  With the above operation, the emergency notification operation can be performed only for the reception-side mobile communication terminal in the vicinity of the transmission-side mobile communication terminal that has requested rescue.

  FIG. 4 is a flowchart for explaining the operation of the mobile communication terminal according to the first embodiment of the present invention. FIG. 4 (a) shows an operation as a transmitting-side mobile communication terminal that transmits an emergency notification mail. FIG.4 (b) shows the operation | movement as a receiving side mobile communication terminal which receives an emergency alert mail.

  With reference to Fig.4 (a), the operation | movement as a transmission side portable communication terminal which transmits an emergency alert mail is demonstrated.

  When the emergency notification mail generation unit detects an emergency operation performed by the user (S210), the location information acquisition unit acquires the location information of the terminal itself as the transmission side location information (S211).

  The emergency notification mail generation unit generates and outputs an emergency notification mail including predetermined information for notifying an emergency, a predetermined emergency notification destination mail address, and transmission side position information (S212).

  Then, the mail transmission means transmits the emergency notification mail generated by the emergency notification mail generation means to the communication network (S213).

  Next, with reference to FIG. 4B, the operation as a receiving-side mobile communication terminal that receives an emergency notification mail will be described.

  The mail receiving means identifies and receives the emergency notification mail from the communication network (S220). Then, the mail receiving means outputs the received emergency notification mail together with emergency notification operation execution necessity determination instruction information for instructing whether or not the emergency notification operation needs to be performed (S221).

  The emergency notification operation executing means inputs the emergency notification mail output by the mail receiving means and the emergency notification operation execution necessity determination instruction information, and acquires the position information of the own terminal as the receiving side position information by the position information acquisition means (S222). ).

  The emergency notification operation executing means extracts the transmission side position information from the emergency notification mail (S223), and based on the acquired reception side position information and the extracted transmission side position information, the distance between the reception side position and the transmission side position Is calculated (S224).

  When the calculated distance is within the threshold (S225, YES), the emergency notification operation executing means displays a message corresponding to the predetermined information for notifying the emergency included in the emergency notification mail and performs the emergency notification operation. This is performed (S226).

  If the calculated distance is not within the threshold (S225, NO), the process ends without doing anything.

  By the above operation, the emergency notification operation is performed only when the own terminal is located in the vicinity of the mobile communication terminal that has requested rescue.

As described above, in the present embodiment, the emergency notification operation is not performed in the mobile communication terminal that is far away from the mobile communication terminal that is experiencing an emergency. Therefore, the emergency notification information can be efficiently notified to the rescuer according to the situation of the rescue requester who encounters the emergency without calling many people unnecessarily.

(Second Embodiment)
The first embodiment is suitable when this emergency notification service is provided for a limited area. However, if the target area is widened and the number of subscribed users registered in the emergency notification server is increased, the possibility of transmitting an emergency notification mail to a large number of subjects increases. In such a case, mail traffic is unnecessarily increased, which is not preferable.

  Therefore, the second embodiment is characterized in that an emergency notification mail is transmitted only to a location registration area where a mobile communication terminal that is encountering an emergency situation is located.

  With respect to the second embodiment, configurations of an emergency notification system, a mobile communication terminal, and an emergency notification server will be described with reference to the drawings.

For example, an emergency call message, an emergency call message code corresponding to the emergency call message, and an emergency notification destination mail address are stored. Further, the identification information of the user of the mobile communication terminal 15 and the identification information of the terminal are also stored. Of course, the ROM described above also corresponds to the storage unit 155, and a program relating to the emergency notification service is also stored.

  FIG. 7 is a block diagram illustrating a configuration of the emergency notification server 21 according to the second embodiment.

  The emergency notification server 21 includes an emergency notification mail delivery control unit 210, a mail reception unit 211, a mail transmission unit 212, a DB (database) 213, and a DB information management unit 214.

  The emergency notification mail distribution control unit 210 controls the distribution of emergency notification mail.

  The mail receiving unit 211 receives an emergency notification mail transmitted from the mobile communication terminal. In addition, the mail transmission unit 212 transmits the emergency notification mail edited by the emergency notification mail delivery control unit 210 to the mobile communication terminal. The mail reception unit 211 and the mail transmission unit 212 are connected to a communication network C (for example, the Internet).

  The DB 213 is a database for registering with the emergency notification service and storing user information. The contents of the database will be described later.

  The DB information management unit 214 is connected to each carrier's HLR (HLR-A, HLR-B), and receives location registration area information of the mobile communication terminal for each carrier that is updated in real time. Then, update registration is performed in the DB 213.

  The emergency notification mail delivery control unit 210 and the DB information management unit 214 are realized by a CPU (not shown) reading a program stored in the ROM and executing the program.

  FIG. 8 is an example of data items of a database (DB 213) managed by the emergency notification server 21. Information registered in the DB 213 includes user ID 2131, terminal ID 2132, e-mail address 2133, business operator ID 2134, and location registration area ID 2135 as information of users who have subscribed to the emergency notification service.

  The user ID 2131 is user identification information of the mobile communication terminal.

  The terminal ID 2132 is terminal identification information of the mobile communication terminal.

  A mail address 2133 is a mail address of the mobile communication terminal.

  The carrier ID 2134 is identification information of a telecommunications carrier that provides a communication service to the mobile communication terminal.

  The location registration area ID 2135 is identification information of a location registration area where the mobile communication terminal is located.

  The user ID 2131, the terminal ID 2132, the mail address 2133, and the business operator ID 2134 are information registered when each user subscribes to the emergency notification service.

  The location registration area ID 2135 is information indicating in which location registration area of the communication carrier the mobile communication terminal is currently located. Each time the mobile communication terminal moves to a different location registration area, it makes a location registration request to the HLR of the communication network. Update information of the location registration area of the mobile communication terminal managed by the HLR is provided to the emergency notification server 21.

  In other words, when the location registration area information of the mobile communication terminal is sent from each communication carrier's HLR, the DB information management unit 214 described above searches the DB 213 using the carrier ID and user ID as keys. Then, the location registration area ID 2135 corresponding to the corresponding user ID 2131 is rewritten with the received location registration area information.

  Note that the DB 213 includes, in addition to the user information shown in FIG. 8, data for each telecommunications carrier location registration area corresponding to the correspondence relationship between location registration areas for each telecommunications carrier. The location registration area corresponding data for each communication carrier indicates the matching status and the difference status of the location registration areas set by each communication carrier.

  Next, the operation of the second embodiment will be described.

  FIG. 9 is a flowchart illustrating the operation of the mobile communication terminal according to the second embodiment as a transmission-side mobile communication terminal.

  A user who encounters an emergency situation operates an predetermined operation of a predetermined key or button of the input / output unit 151 of the mobile communication terminal 15 to execute an emergency operation for transmitting an emergency notification mail (S300). Normally, when an emergency situation is encountered, there is no time and there is no time, so it is desirable that everything be executed by one-touch operation of a key or button. However, in consideration of a case where there is a certain margin, an emergency type indicating what kind of emergency may be selected.

  The emergency operation input at the input / output unit 151 is detected by the emergency notification mail generation function unit of the control unit 152 (S301).

  The emergency notification mail generation function unit that has detected the emergency operation activates the GPS unit 154 and acquires the latitude and longitude information of its own terminal as the transmission side location information (S302).

  Subsequently, the emergency notification mail generation function unit reads the emergency notification message code, the emergency notification destination mail address, the user identification information, and the terminal identification information stored in the storage unit 155.

  Hereinafter, the user identification information and the terminal identification information are referred to as a user ID and a terminal ID, respectively.

  The emergency notification destination email address is the email address of the emergency notification server 21 that receives the emergency notification email.

  Further, the emergency call message code is code information corresponding to a message having a content requesting rescue in the event of an emergency. When the emergency type is selected, an emergency call message code corresponding to a message of contents corresponding to each emergency, for example, an accident, a fire, a poor physical condition or the like is read. That is, the emergency notification mail according to the present embodiment includes not the character string of the message but code information (number or alphabet) corresponding to the message as the content of the message part of the mail.

  The emergency notification mail generation function unit generates an emergency notification mail from the transmission side position information acquired from the GPS unit 154 and the predetermined information read from the storage unit 155 (S303).

  The emergency notification mail is analyzed by the emergency notification server 21 and the mobile communication terminal on the receiving side. For this reason, the information constituting the emergency notification mail uses numbers and character codes that are not garbled even through the gateway of each communication network on the way. Each piece of information written in the message part of the mail is separated by “new line, / or;” etc., and the type and meaning of information are defined in the order of appearance. For example, “EMERGENCY” is assigned as a title to a body composed of “user ID; terminal ID; transmission side position information; emergency call message code”, and “emergency notification destination mail address” is a destination mail. Created.

  The emergency notification mail created in this way is output from the mail transmission function unit of the control unit 152 (S304).

  The emergency notification mail output from the mail transmission function unit is sent to the mail server of the communication carrier via the base station in the communication network by the wireless transmission function of the wireless transmission / reception unit 153. Then, the emergency notification mail is transferred from the mail service provider's mail server by SMTP based on the emergency notification destination mail address, and reaches the emergency notification server 21.

  Next, the processing operation of the emergency notification mail that reaches the emergency notification server 21 will be described with reference to FIG.

  FIG. 10 is a flowchart showing the operation of the emergency notification server 21 of the second embodiment.

  When receiving the emergency notification mail (S400), the mail receiving unit 211 of the emergency notification server 21 analyzes the content of the received emergency notification mail and extracts the user ID and the terminal ID.

  The user ID and terminal ID extracted by the mail receiving unit 211 are sent to the emergency notification mail delivery control unit 210 together with the emergency notification mail. The emergency notification mail delivery control unit 210 identifies the user ID and the terminal ID, and authenticates that the user is registered in the DB 213 (S401).

  The emergency notification mail delivery control unit 210 searches the DB 213 based on the user ID included in the emergency notification mail to identify the registered user ID 2131. Then, the content of the location registration area ID 2135 corresponding to the registered user ID 2131 is identified as the location registration area (transmission location registration area) of the user who has transmitted the emergency notification mail. At the same time, the operator ID 2134 (transmission operator ID) corresponding to the user ID 2131 is also identified (S402).

  Then, the emergency notification mail delivery control unit 210 searches the DB 213 for other registered users having the same transmission location registration area and the same transmission provider ID, and acquires the mail addresses of the other registered users that match (S403). . The mail address obtained from the search result of the DB 213 is reset as the destination address of the emergency notification mail received by the mail receiving unit 211 (S404). That is, an emergency notification mail is generated by rewriting the emergency notification destination mail address attached to the received emergency notification mail with the mail address obtained from the search result of the DB 213.

  As a result of the search, if there are a plurality of other registered users that match, the emergency notification mail is copied, and a plurality of emergency notification mails that are rewritten to the respective mail addresses obtained from the search results of the DB 213 are generated.

  The generated emergency notification mail is transmitted from the mail transmission unit 212 to the mobile communication terminal corresponding to the mail address (S405).

  In step S403, the emergency notification mail delivery control unit 210 refers to the above-mentioned location registration area correspondence data for each communication carrier, and identifies the location registration area of another communication carrier corresponding to the transmission location registration area. May be. That is, the location registration area correspondence data for each communication carrier indicates the matching status and the difference status of the location registration areas set by each communication carrier. For this reason, the mobile communication terminals of other communication carriers located in the location registration area of another communication carrier that matches the transmission location registration area can also be targeted for delivery of emergency notification mail.

  Furthermore, the control for including the other communication carrier's mobile communication terminals in the emergency notification mail delivery target is performed only when the number of the same communication carrier's mobile communication terminals is smaller than a predetermined number. May be.

  Further, it is usually assumed that the emergency notification mail is distributed to a plurality of mobile communication terminals. Therefore, a multicast mail address may be used for the emergency notification mail distribution of the emergency notification service in advance in consultation with each communication carrier. In this case, the multicast mail address may be an address having a local part common to each communication carrier indicating multicast mail and having the domain name of the communication carrier as the domain name.

  Then, a plurality of mail addresses obtained by the search result of the DB 213, which is a target for multicast transmission, may be written in one emergency notification mail, and the multicast mail address described above may be set and distributed. In this way, since only one emergency notification mail is delivered to each communication carrier, it is possible to contribute to avoiding congestion of mail traffic.

  In this case, the mail server of each communication carrier identifies each of the plurality of mail addresses written in the received multicast mail address, and individually distributes incoming mail.

  The operation when the emergency notification mail distributed as described above is received by the mobile communication terminal on the receiving side will be described with reference to FIG.

  FIG. 11 is a flowchart illustrating the operation of the mobile communication terminal according to the second embodiment as a reception-side mobile communication terminal.

  The mail reception function unit of the control unit 152 of the mobile communication terminal 15 identifies and receives the emergency notification mail from the communication network via the wireless transmission / reception unit 153 (S500).

  Similarly to the first embodiment, information that can identify that the mail type is an emergency notification mail is added to the mail incoming notification sent from the communication network to the mobile communication terminal 15. When the mail receiving function unit receives the notification that the mail has arrived at the mail server and identifies that the mail type is the emergency notification mail, the mail reception function unit transmits the reception request to the mail server and receives the emergency notification mail. . In other words, the mail reception function unit that has identified that the incoming mail is an emergency notification mail performs an operation of fetching the incoming mail from the mail server without notifying the user of the incoming mail information.

  Then, the mail reception function unit outputs the received emergency notification mail to the emergency notification operation execution function unit together with emergency notification operation execution necessity determination instruction information for instructing whether or not to execute the emergency notification operation (S501). .

  The emergency notification operation execution function unit inputs the emergency notification mail and the emergency notification operation execution necessity determination instruction information, and determines whether or not the emergency notification operation needs to be executed.

  For this reason, the emergency notification operation execution function unit first acquires the latitude and longitude information of the terminal as the reception side location information using the GPS unit 154 (S502), and extracts the transmission side location information from the emergency notification mail (S503). ). Then, the emergency notification operation execution function unit calculates the distance between the reception side position and the transmission side position based on the acquired reception side position information and the extracted transmission side position information (S504).

  The emergency notification operation execution function unit reads the distance Xm preset as a threshold value from the storage unit 155 and compares it with the calculated distance. It is confirmed whether or not the calculated distance between the reception side position and the transmission side position is smaller than the threshold distance Xm (S505). When the calculated distance between the reception side position and the transmission side position is smaller than the threshold distance Xm (S505, YES), the emergency notification operation execution function unit determines that the emergency notification operation needs to be executed.

  The emergency notification operation execution function unit that has determined that it is necessary to execute the emergency notification operation reads the emergency message corresponding to the emergency notification message code from the storage unit 155. Then, an emergency notification operation execution instruction is issued to the input / output unit 151 (S506).

  If the calculated distance between the reception side position and the transmission side position is larger than the threshold distance Xm (S505, NO), the emergency notification operation execution function unit does nothing and ends the process. In this case, the received emergency notification mail may be deleted. This is because the mobile communication terminal that does not perform emergency notification does not even notify the user that the emergency notification mail has been received.

  Receiving the emergency notification operation execution instruction from the emergency notification operation execution function unit, the input / output unit 151 displays the instructed emergency notification message on the display and outputs a sound for notifying emergency from the speaker (S507). For example, “There is an emergency within Xm from the current location” is displayed on the display.

  By the above operation, the emergency notification operation is performed only when the own terminal is located in the vicinity of the mobile communication terminal that has requested rescue.

As described above, in the present embodiment, the emergency notification mail is not distributed to the mobile communication terminal that is far away from the mobile communication terminal that encounters an emergency. Further, even if the mobile communication terminal is distributed with the emergency notification mail, the emergency notification operation is not performed except for the mobile communication terminals in the vicinity of the mobile communication terminal encountering an emergency. That is, an unnecessarily large number of emergency notification mails are not distributed and an unnecessarily large number of people are not called. Therefore, emergency notification information can be efficiently notified to the rescuer according to the situation of the rescue requester who has encountered an emergency.

(Modification 1 of 2nd Embodiment)
Modification 1 of the second embodiment adds azimuth information to the emergency notification information of the receiving mobile communication terminal so that the rescuer can more easily identify the position of the rescue requester.

  The mobile communication terminal of Modification 1 of the second embodiment has substantially the same configuration as the mobile communication terminal 15 described with reference to FIG. The difference is that the emergency notification operation execution function unit of the control unit 152 includes a message editing unit (not shown). This message editing unit has a function of editing a message displayed on the display of the input / output unit 151.

  FIG. 12 is a flowchart showing the operation of the reception-side mobile communication terminal in the first modification of the second embodiment. This is up to step S505 for determining whether or not an emergency notification operation is necessary in the flowchart illustrating the operation of the mobile communication terminal according to the second embodiment as the receiving mobile communication terminal described with reference to FIG. The same.

  That is, the emergency notification operation execution function unit of the control unit 152 of the reception-side mobile communication terminal determines whether the emergency notification operation needs to be performed based on the distance between the transmission-side position that is the rescue requester and the reception-side position that is the own terminal. Is determined (S505). If it is determined that the emergency notification operation needs to be executed (S505, YES), the direction of the rescue requester viewed from the own terminal based on the transmission side position as the rescue requester and the reception side position as the own terminal Is calculated (S516).

  The emergency notification operation execution function unit reads the emergency message corresponding to the emergency notification message code from the storage unit 155. Then, the message editing unit adds the azimuth information obtained in step S516 to the read message and performs the message editing (S517).

  Subsequently, the emergency notification operation execution function unit issues an emergency notification operation execution instruction to the input / output unit 151 together with the edited message (S518).

  Receiving the emergency notification operation execution instruction from the emergency notification operation execution function unit, the input / output unit 151 displays the edited message including the azimuth information on the display and outputs a sound notifying the emergency from the speaker. For example, “There is an emergency within Xm south of the current location.” Is displayed on the display.

By the above operation, the emergency notification operation indicating the direction and distance of the rescue requester is performed only when the terminal is located in the vicinity of the mobile communication terminal that requested the rescue. The rescuer can easily identify the rescue requester by the direction and distance.

(Modification 2 of the second embodiment)
In the second modification of the second embodiment, the time information when the emergency notification mail is generated by the rescue requester is transmitted to the rescuer, and the rescue request occurrence time information is added to the emergency notification information of the receiving-side mobile communication terminal. Is.

  The mobile communication terminal according to the second modification of the second embodiment has substantially the same configuration as the mobile communication terminal 15 described with reference to FIG.

  FIG. 13 is a flowchart illustrating the operation of the transmission-side mobile communication terminal according to the second modification of the second embodiment. This is the same up to step S302 for acquiring the transmission side position information in the flowchart showing the operation of the portable communication terminal of the second embodiment as the transmission side portable communication terminal described with reference to FIG. .

  That is, the emergency notification mail generation function unit of the control unit 152 of the transmission-side portable communication terminal acquires the latitude and longitude information of the terminal as transmission-side position information (S302). Further, current time information is acquired as emergency occurrence time information (S323).

  Subsequently, the emergency notification mail generation function unit reads the emergency notification message code, the emergency notification destination mail address, the user ID, and the terminal ID stored in the storage unit 155.

  The emergency notification mail generation function unit generates an emergency notification mail from the transmission side position information, the emergency occurrence time information, and the predetermined information read from the storage unit 155 (S324).

  The emergency notification mail generated as described above is transmitted (S325).

  On the other hand, the emergency notification mail including the emergency occurrence time information is received by the receiving side mobile communication terminal. And when the receiving side mobile communication terminal is located in the vicinity of the mobile communication terminal which requested the rescue, the emergency notification operation is executed, and the emergency occurrence time information included in the emergency notification mail is also displayed. That is, when the emergency notification operation in step S507 in FIG. 11 or step S519 in FIG. 12 is executed, the emergency occurrence time is displayed together with the emergency notification message.

With the above operation, time information when the rescue requester encounters an emergency is transmitted, and an emergency notification operation is performed in which the time information is displayed on the rescuer's mobile communication terminal.

(Modification 3 of the second embodiment)
In the third modification of the second embodiment, when the emergency occurrence time added in the second modification has passed a predetermined time, the emergency notification operation in the receiving-side mobile communication terminal is not performed. is there. This is because the receiving mobile communication terminal that was in a power-off state or out-of-service state at the time the rescue requester made a rescue request was able to communicate with the base station and then respond to the emergency notification mail received. It is a matter of necessity.

  The mobile communication terminal according to Modification 3 of the second embodiment has substantially the same configuration as the mobile communication terminal 15 described with reference to FIG. The difference is that the emergency notification operation execution function unit of the control unit 152 includes a time determination processing unit (not shown).

  FIG. 14 is a flowchart showing the operation of the reception-side mobile communication terminal in the third modification of the second embodiment. This is the same up to step S501 instructing the necessity of emergency notification in the flowchart showing the operation of the reception-side mobile communication terminal of the first modification of the second embodiment described with reference to FIG. The same applies to Step S501 for instructing the necessity of emergency notification in the flowchart showing the operation of the mobile communication terminal on the receiving side according to the second embodiment described with reference to FIG.

  That is, when the emergency notification operation execution function unit of the control unit 152 of the receiving-side mobile communication terminal receives an instruction for determining whether or not an emergency notification operation is necessary from the mail reception function unit, the emergency occurrence time written in the emergency notification mail is set. Identify (S532).

  The time determination processing unit of the emergency notification operation execution function unit compares the identified emergency occurrence time with the current time, and determines whether or not the time difference is within a predetermined Z time (S533). The predetermined Z time may be determined from the time normally required until the situation is resolved after the emergency request is issued.

  Then, when the determined time difference exceeds the predetermined Z time, the time determination processing unit of the emergency notification operation execution function unit ends the process without doing anything (S533, NO).

  This is because it is possible to determine that the situation has subsided at the present time by an emergency notification mail related to a rescue request generated while the mobile communication terminal is in a power-off state or out-of-service state. In this case, the received emergency notification mail may be deleted. This is because the mobile communication terminal that does not perform emergency notification does not even notify the user that the emergency notification mail has been received.

  On the other hand, when the determined time difference is within the predetermined Z time (S533, YES), the time determination processing unit of the emergency notification operation execution function unit causes the processes after step S534 to be executed. The processing after step S534 is the same as the processing after step S502 in FIG. 11 or FIG.

As a result of the above operations, the emergency notification notified when the emergency notification is no longer necessary for the receiving mobile communication terminal that was in a power-off or out-of-service state when an emergency occurred It becomes possible to do.

(Modification 4 of the second embodiment)
In the fourth modification of the second embodiment, map information and position information of the sun and moon at the current time are included in the emergency notification information of the receiving mobile communication terminal so that the position of the rescue requester can be more easily specified. Is added.

  The mobile communication terminal according to Modification 4 of the second embodiment has substantially the same configuration as the mobile communication terminal 15 described with reference to FIG. The difference is that the emergency notification operation execution function unit of the control unit 152 includes a message editing unit (not shown). This message editing unit has a function of editing a message displayed on the display of the input / output unit 151.

  FIG. 15 is a flowchart showing the operation of the reception-side mobile communication terminal in the fourth modification of the second embodiment. This is the same up to step S516 in which the azimuth calculation is performed in the flowchart showing the operation of the reception-side mobile communication terminal of the first modification of the second embodiment described with reference to FIG. Further, the process is substantially the same up to step S538 in which the direction is calculated in the flowchart illustrating the operation of the reception-side mobile communication terminal according to the third modification of the second embodiment described with reference to FIG.

  That is, the emergency notification operation execution function unit of the control unit 152 of the reception-side mobile communication terminal determines that the emergency notification operation is necessary, and calculates the orientation of the transmission side position as the rescue requester from the own terminal in step S516. . Next, the emergency notification operation execution function unit reads map information and astronomical position information from the storage unit 155 based on the transmission side position, the reception side position, the direction, and the current time (S547). The celestial body position information is information indicating the direction of the sun in the daytime and the direction of the moon in the nighttime based on the date and time.

  Further, the emergency notification operation execution function unit reads an emergency message corresponding to the emergency notification message code from the storage unit 155. Then, the message editing unit adds the azimuth information calculated in step S516 to the read message in the message editing unit (S548).

  Subsequently, the emergency notification operation execution function unit issues an emergency notification operation execution instruction to the input / output unit 151 (S549).

  Receiving the emergency notification operation execution instruction from the emergency notification operation execution function unit, the input / output unit 151 displays the edited message and map including the direction information on the display, and outputs a sound informing the emergency from the speaker. For example, “There is an emergency within Xm south of the current location.” Is displayed on the display. In addition, a map showing the position of the rescue requester and the terminal itself is displayed on the display together with the direction information of the sun or the moon.

The rescuer can more easily identify the rescue requester by using the map information and the celestial direction information in addition to the direction and distance information.

(Third embodiment)
In the second embodiment described above, the other mobile communication terminal that is the same as the location registration area where the rescue requester is located is set as the emergency notification mail distribution target. This is because the communication carrier's HLR data can be used as the location of each mobile communication terminal.

  However, in order to prevent frequent location registration operations, telecommunications carriers usually set location registration areas on a prefecture basis. Therefore, even if it is the other mobile communication terminal that is the same as the location registration area where the rescue requester is located, there is also a mobile communication terminal that is quite far from the location of the rescue requester.

  On the other hand, the mobile communication terminal performs a cell search, and can identify the base station area in which the mobile communication terminal is located based on information constantly transmitted from the base station. Therefore, if the mobile communication terminal is configured to notify the emergency notification server of the in-zone base station area information every time the base station moves through the report mail, the in-zone base station area of the mobile communication terminal can be managed. .

  The third embodiment has such a system configuration.

  FIG. 16 is a block diagram illustrating a configuration of the emergency notification system 210 according to the third embodiment.

  The configuration of the emergency notification system 210 is different from the emergency notification system 200 of the second embodiment shown in FIG. 5 in that the emergency notification server 22 is not connected to the carrier's HLR. The mobile communication terminal 15-a1 and the mobile communication terminal 16-a1 are terminals of the same communication operator, and the mobile communication terminal 17-b1 and the mobile communication terminal 18-b1 are different from the same communication operator. It is a terminal. When the mobile communication terminal turns on the terminal and performs cell search to start communication with the base station in the area where the mobile communication terminal is located, the base station area information identified at that time is sent by e-mail to the emergency notification server for reporting To do. And whenever it moves and a base station area changes, the update information is transmitted by e-mail to an emergency notification server, and is reported.

  The mobile communication terminal of the third embodiment has substantially the same configuration as the mobile communication terminal 15 described with reference to FIG. The difference is that the emergency notification mail generation function unit of the control unit 152 includes a function of generating an area change report mail described later.

  FIG. 17 is a block diagram illustrating a configuration of the emergency notification server 22 according to the third embodiment. In the emergency notification server 22, the DB information management unit 224 updates the base station area information based on the area change report mail, instead of acquiring the location registration area information from the HLR of the communication carrier. Accordingly, the DB 223 uses the base station area ID instead of the location registration area ID 2135 in the data item of the DB 213 shown in FIG.

  The operation of the third embodiment will be described with reference to FIGS.

  FIG. 18 is a flowchart illustrating an operation in which the mobile communication terminal according to the third embodiment transmits an area change report mail.

  The mobile communication terminal can know the base station area information in the area by performing a cell search when the power is turned on. At this time, the first area change report mail is generated and transmitted to the emergency notification server to report the area of the base station in the area. Although the flowchart of this operation is omitted, the area change report mail is the same as the following explanation.

  When the base station area changes due to movement, the mobile communication terminal receives new base station area information. The mobile communication terminal stores the base station area information of the area in which it is located in the storage unit, and updates it whenever there is a change.

  As described above, when the mobile communication terminal identifies that the base station has changed (S600), the mobile communication terminal updates the base station area information (S601). Then, the emergency notification mail generation function unit of the control unit 152 generates an area change report mail in order to report the updated base station area information to the emergency notification server 22 (S602).

  In the area change report mail, the user ID, the terminal ID, and the updated base station area ID are set as the mail contents. Similar to the emergency notification mail described above, each piece of information written in the message part of the mail is separated by “new line, / or;” etc., and the type and meaning of information are defined in the order of appearance. Then, a title set in advance as the area change report mail is attached, and the emergency notification destination mail address is set as the destination of the emergency notification server 22. In addition, in order to distinguish from the emergency notification mail, another mail address destined for the emergency notification server 22, for example, an area change report destination mail address may be used. For example, for example, “AREA UPDATE” is added as a title to the body composed of “user ID; terminal ID; base station area ID”, and “area change report destination email address” is created as a destination email. .

  The area change report mail generated in this way is transmitted from the mobile communication terminal (S603).

  FIG. 19 is a flowchart showing an operation of updating the database (DB 223) by the emergency notification server 22 according to the third embodiment.

  When the mail receiving unit 221 of the emergency notification server 22 receives the mail and identifies it as an area change report mail (S700), it sends the received area change report mail to the DB information management unit 224. The mail receiving unit 221 identifies the mail as the area change report mail by the destination mail address (area change report destination mail address) or the title (AREA UPDATE) of the received mail.

  The DB information management unit 224 analyzes the contents of the transferred area change report mail. Then, the DB information management unit 224 identifies the user ID and the terminal ID and authenticates that the user is registered in the DB 223 (S701).

  The DB information management unit 224 identifies the updated base station area ID from the contents of the area change report mail (S702). Then, the content of the base station area ID corresponding to the user ID registered in the DB 223 is updated with the base station area ID reported in the area change report mail (S703).

  In this way, the emergency notification system 210 of the third embodiment manages the area of the base station in which the mobile communication terminal is located.

  Note that the DB 223 includes base station area position information data corresponding to the communication carrier in addition to data corresponding to the data items of the DB 213 illustrated in FIG. This shows the geographical position information of the base station area for each communication carrier, and also shows the geographical proximity of the base stations installed by each communication carrier.

  The operation of transmitting the emergency notification mail in the emergency notification system 210 of the third embodiment configured as described above is the same as that of the second embodiment described with reference to FIG.

  In addition, the emergency notification mail delivery operation in the emergency notification system 210 of the third embodiment is substantially the same as that of the second embodiment described with reference to FIG. That is, the “location registration area” in step S402 and step S403 may be read as “base station area”.

  Therefore, not only the base station area of the same carrier, but also the base station areas of other carriers corresponding to the base station area may be identified to determine the emergency notification mail delivery target. For this control, base station area position information data corresponding to the carrier is used.

  Similarly to the second embodiment, a multicast mail address may be used in advance for delivery of a plurality of emergency notification mails of the emergency notification service by previously negotiating with each communication carrier.

  Furthermore, the operation of receiving the emergency notification mail in the emergency notification system 210 of the third embodiment is the same as that of the second embodiment described with reference to FIG.

  Furthermore, it goes without saying that the modified examples 1 to 4 of the second embodiment described with reference to FIGS. 12 to 15 are also applicable to the third embodiment.

In the third embodiment configured as described above, the emergency notification mail can be distributed to the base station area further narrowed down from the location registration area, so that an unnecessarily large number of emergency notification mails are distributed. Nothing will happen.

(Fourth embodiment)
According to the emergency notification system of the fourth embodiment, the emergency notification server uses a distance threshold value used by the receiving mobile communication terminal to determine whether or not the emergency notification operation needs to be executed, according to the number of persons to whom the emergency notification mail is distributed. Make it variable.

  FIG. 20 is a flowchart showing the operation of the emergency notification server according to the fourth embodiment of the present invention. This emergency notification server may have the configuration of the emergency notification server 21 described with reference to FIG. 7 or the configuration of the emergency notification server 22 described with reference to FIG. The difference is that the emergency notification server includes a function of determining the above-mentioned distance threshold and adding the distance threshold to the emergency notification mail for distribution.

  The operation flow in FIG. 20 is described according to the operation flow in FIG. 10 which is the operation of the emergency notification server 21. The operation from step S800 to step S803 is the same as the operation from step S400 to step S403 in FIG. In the following description, the location registration area may be read as a base station area.

  In step S803, the emergency notification mail delivery control unit searches the database for other registered users having the same transmission location registration area and the same transmission provider ID, and extracts the other registered users that match as notification targets. Then, the number of registered users (number of mobile communication terminals) to be extracted is identified (S804).

  In the database, a plurality of distance threshold values used by the receiving-side mobile communication terminal for determining whether or not an emergency notification operation is necessary are stored in advance according to the number of users to be notified. The emergency notification mail delivery control unit acquires a distance threshold corresponding to the identified number of mobile communication terminals from the database (S805).

  The emergency notification mail delivery control unit writes the acquired distance threshold as additional information in the received emergency notification mail (S806).

  When the above editing is completed, the emergency notification mail delivery control unit resets the notification target mail address acquired in step S803 as the destination address of the received emergency notification mail (S807). That is, the number of emergency notification mails in which the distance threshold is written in step S806 is copied. Then, a plurality of emergency notification emails are generated by rewriting the emergency notification destination email addresses attached to the received emergency notification emails to the respective email addresses obtained from the database search results.

  The generated emergency notification mail is transmitted from the mail transmitting unit to the mobile communication terminal corresponding to each mail address (S808).

  The other emergency notification mail delivery operations are the same as the delivery operations of the second and third embodiments.

  That is, not only the location registration area of the same telecommunications carrier but also the location registration area of another telecommunications carrier corresponding to the location registration area may be identified to determine the delivery target of the emergency notification mail. Needless to say, the distance threshold is also determined including the number of other telecommunications carrier users who are located in the location registration area of the other telecommunications carrier in order to distribute the emergency notification mail.

  Moreover, it is possible to use a multicast mail address in advance for the delivery of a plurality of emergency notification mails of this emergency notification service by previously consulting with each communication carrier.

  The operation when the emergency notification mail distributed as described above is received by the mobile communication terminal on the receiving side will be described with reference to FIG.

  FIG. 21 is a flowchart illustrating the operation of the reception-side mobile communication terminal according to the fourth embodiment. Note that the mobile communication terminal of the fourth embodiment has substantially the same configuration as the mobile communication terminal 15 described with reference to FIG. The difference is that the emergency notification operation execution function unit of the control unit 152 uses the distance threshold included in the received emergency notification mail as a distance threshold used for determining whether or not to execute the emergency notification operation.

  The operation flow of FIG. 21 is described according to the operation flow of FIG. 11 which is the operation of the mobile communication terminal 15 on the receiving side. The operation from step S900 to step S903 is the same as the operation from step S500 to step S503 in FIG.

  When the emergency notification operation execution function unit of the control unit 152 of the mobile communication terminal 15 completes the acquisition of the reception side location information of the terminal itself and the extraction of the transmission side location information from the emergency notification email, the emergency notification operation execution function unit sets the distance threshold value from the emergency notification email. Extract (S904).

  This distance threshold value is a distance threshold value that is set by the emergency notification server according to the number of distribution targets of the emergency notification mail as described above and used for determining whether or not to execute the emergency notification operation.

  Subsequently, the emergency notification operation execution function unit calculates the distance between the reception side position and the transmission side position based on the acquired reception side position information and the extracted transmission side position information (S905).

  Then, the emergency notification operation execution function unit compares the distance threshold value extracted from the emergency notification mail (for example, the distance Ym) with the calculated distance. It is checked whether the calculated distance between the reception side position and the transmission side position is smaller than the distance threshold distance Ym (S906). When the calculated distance between the reception side position and the transmission side position is smaller than the distance threshold distance Ym (S906, YES), the emergency notification operation execution function unit determines that the emergency notification operation needs to be executed.

  The emergency notification operation execution function unit reads the emergency message corresponding to the emergency notification message code from the storage unit 155. Then, the message is edited based on the distance threshold obtained in step S904 (S907), and an emergency notification operation execution instruction is issued to the input / output unit 151 together with the edited message (S908).

  Receiving the emergency notification operation execution instruction from the emergency notification operation execution function unit, the input / output unit 151 displays the instructed emergency notification message on the display and outputs a sound for notifying emergency from the speaker (S909). For example, “There is an emergency that occurred within Ym from the current location.” Is displayed on the display.

  If the calculated distance between the reception side position and the transmission side position is greater than the distance threshold distance Ym (NO in S906), the emergency notification operation execution function unit does nothing and ends the process. In this case, the received emergency notification mail may be deleted. This is because the mobile communication terminal that does not perform emergency notification does not even notify the user that the emergency notification mail has been received.

  With the above operation, the range in which the emergency notification mail is distributed can be changed according to the number of rescuers present in the vicinity of the mobile communication terminal that has requested rescue.

In the present embodiment, it becomes possible to deliver an emergency notification mail according to the situation around the rescue requester who is experiencing an emergency situation, so that an unnecessarily large number of people are called or the number of people calling is extremely small. Can be prevented.

(Fifth embodiment)
Stopping the alarm ringing by the emergency notification operation and storing the emergency notification message display in the receiving mobile communication terminal of each embodiment described above can be arbitrarily operated by the user of the receiving mobile communication terminal.

  The fifth embodiment is an emergency notification system in which a rescuer who has received an emergency notification mail as described in each embodiment completes the rescue requester's rescue and notifies that the emergency has been resolved. . In addition, the emergency notification system can monitor the completion of the rescue in response to the rescue request so that the rescue request is not left without being rescued.

  The mobile communication terminal used in the fifth embodiment may be the mobile communication terminal 15 having the configuration described with reference to FIG. The difference is that the emergency notification mail generation function unit of the control unit 152 of the mobile communication terminal 15 includes an emergency release function described below.

  Further, the emergency notification server used in the fifth embodiment may have the configuration of the emergency notification server 21 described with reference to FIG. 7, or the emergency notification server 22 described with reference to FIG. It may be a configuration. The difference is that the emergency notification mail delivery control unit includes an emergency release monitoring function described below.

  The operation of the fifth embodiment will be described with reference to FIGS.

  FIG. 22 is a flowchart showing the operation of the rescuer's portable communication terminal according to the fifth embodiment of the present invention. That is, it is the receiving-side mobile communication terminal in each of the embodiments described above.

  When a rescuer who knows that an emergency has occurred by the emergency notification mail delivered from the emergency notification server arrives at the rescue requester and completes the specified rescue, he / she completes the emergency release operation and the rescue is completed. Is reported (S1000). The input / output unit 151 of the mobile communication terminal 15 is provided with a predetermined key or button for emergency release operation.

  The emergency release operation input at the input / output unit 151 is detected by the emergency notification mail generation function unit of the control unit 152 (S1001). As described above, the emergency notification mail generation function unit includes an emergency release function (hereinafter referred to as an emergency release mail generation function unit) described below.

  The emergency release mail generation function unit that has detected the emergency release operation generates an emergency release mail that reports that the rescue has been completed (S1002). In the emergency release mail, the user ID and terminal ID of the mobile communication terminal are set as the mail contents. Then, a title preset as an emergency release mail, for example, “EMERGENCY ELIMINATION” is added, and an emergency notification destination mail address is set as a destination of the emergency notification server. Here, in order to distinguish from the emergency notification mail, for example, an emergency release destination mail address, which is another mail address destined for the emergency notification server, is used.

  The emergency release mail generated in this way is transmitted from the mobile communication terminal (S1003).

  The emergency release mail transmitted from the mobile communication terminal is received by the emergency notification server, and the emergency release mail is distributed to other mobile communication terminals.

  Next, the operation of the emergency notification server according to the fifth embodiment will be described.

  23 and 25 are flowcharts for explaining the operation of the emergency release monitoring function in the emergency notification server.

  FIG. 23 shows the operation in the fifth embodiment when the emergency notification server distributes the emergency notification mail described above. FIG. 25 shows the operation when the emergency notification server receives the emergency release mail and distributes it. FIG. 24 is an example of an emergency notification list used in the fifth embodiment.

  First, with reference to FIG. 23, the operation | movement in 5th Embodiment at the time of the emergency notification server delivering the emergency notification mail mentioned above is demonstrated. This operation corresponds to the operation described with reference to FIGS. 10 and 20, and will be described as an operation in accordance with the operation of FIG.

  The operation from receiving the emergency notification mail to acquiring the registered mobile communication terminal to which the emergency notification mail is distributed from the database and resetting the mail address to the emergency notification mail is the same. That is, the operation from step S1100 to step S1104 in FIG. 23 is the same as that from step S400 to step S404 in FIG.

  Thereafter, in the fifth embodiment, an emergency notification list is created and stored in the database before the emergency notification mail is transmitted (S1105). This emergency notification list is a list in which portable communication terminals that are targets of distribution of emergency notification mail acquired in step S1103 are registered. The contents of the list will be described with reference to FIG.

  When the emergency notification list is created and stored, an emergency notification mail is transmitted to each mail address (S1106).

  FIG. 24 is an example of an emergency notification list.

  One emergency alert list is created for each rescue request.

  As shown in FIG. 24, the items of the emergency notification list are data of the rescue requester who is the transmission source of the emergency notification mail and the rescue responders who are the distribution target of the emergency notification mail extracted in step S1103 of FIG. including. The data item includes a user ID, a terminal ID, a mail address, a business operator ID, and a location registration area ID extracted from the database. The emergency call message code notified by the emergency notification mail is also registered.

  An identification number is assigned to the created emergency notification list. The identification number includes, for example, the year / month / day / hour / minute / second and the serial number in which the emergency notification list is created. Then, the emergency notification list identification number is assigned to the registration data in the database corresponding to the users (rescue requester and rescue responder) included in the emergency notification list. That is, it is linked to whether the registered user in the database is registered in the emergency notification list and in which list.

  Subsequently, the operation of the emergency notification server that has received the emergency release mail transmitted from the rescuer who has completed the rescue will be described with reference to FIG.

  When receiving the emergency release mail (S1200), the mail receiving unit of the emergency notification server analyzes the content of the received emergency release mail and extracts the user ID and the terminal ID.

  The user ID and terminal ID extracted by the mail receiving unit are sent to the emergency notification mail delivery control unit together with the emergency release mail. The emergency notification mail delivery control unit identifies that the emergency release mail is received, identifies the user ID and the terminal ID, and authenticates that the user is registered in the database (S1201). The identification of receiving the emergency release mail can be performed by identifying the emergency release destination mail address or identifying the mail title.

  Since the emergency notification mail delivery control unit has identified that the emergency release mail has been received, the emergency notification mail delivery control unit obtains an emergency notification list associated with the identified user ID from the database (S1202). Then, the e-mail address of the rescue communication person's portable communication terminal registered in the acquired emergency notification list is acquired (S1203).

  That is, the emergency notification server identifies other mobile communication terminals to which the same emergency notification mail that is distributed to the mobile communication terminal that has transmitted the emergency release mail is simultaneously distributed. Then, it notifies the other identified mobile communication terminals that the emergency has been canceled.

  Therefore, the emergency notification mail delivery control unit of the emergency notification server generates an emergency release mail in which the mail address of the mobile communication terminal acquired in step S1203 is set as the destination (S1204). The emergency release mail generated here is an email including a message notifying that the separately notified emergency situation has been released.

  The generated emergency release mail is transmitted from the mail transmission unit of the emergency notification server to the mobile communication terminal corresponding to each mail address (S1205). Note that the emergency release mail may also be distributed in advance with each communication carrier so that a multicast mail address can be used for distributing a plurality of emergency release mails of the emergency notification service.

  When the delivery of the emergency release mail ends, the emergency notification mail delivery control unit deletes the emergency notification list used for the delivery of the emergency release mail from the database (S1206). In addition, the association information with the emergency notification list attached to the corresponding user in the database is deleted.

  The mobile communication terminal on the receiving side handles this emergency release mail in the same way as a normal mail. That is, the mail server of the communication carrier sends a notification of incoming mail to the mobile communication terminal, and the user acquires the incoming mail from the mail server based on the notification.

  On the mobile communication terminal that has received this emergency release mail, a message that the emergency situation requested for rescue has been resolved by the separately notified emergency notification mail is displayed.

  The operation described above is a configuration for notifying that the emergency has been resolved.

  On the other hand, the emergency notification server according to the fifth embodiment performs control for monitoring the completion of the rescue in response to the rescue request so that the rescue request is not left without being rescued despite the rescue request. .

  FIG. 26 is a flowchart illustrating the monitoring control operation executed by the emergency notification server according to the fifth embodiment. The emergency notification mail delivery control unit of the emergency notification server periodically refers to the emergency notification list stored in the database and monitors the rescue completion status. Therefore, this supervisory control is an operation that is periodically activated.

  The emergency notification list is created in step S1105 of the operation described with reference to FIG. 23 and stored in the database. As described above, the emergency notification list is assigned an identification number including the year / month / day / hour / minute / second and serial number of the emergency notification list. In addition, when the emergency release mail is received, this emergency notification list is deleted in step S1206 of the operation described with reference to FIG.

  In other words, the emergency notification list is not deleted unless an emergency release mail is received.

  Therefore, the emergency notification mail delivery control unit of the emergency notification server periodically checks the presence of the emergency notification list (S1300). When the emergency notification list exists, the year / month / day / hour / minute / second generated from the identification number is identified, and the time elapsed until the current time is confirmed.

  If the elapsed time from the creation of the emergency notification list exceeds a predetermined time (for example, 30 minutes), it is determined that the rescue requester has not been rescued yet. Then, the emergency notification mail distribution control unit updates the emergency notification list and redistributes the emergency notification mail.

  First, the emergency notification mail delivery control unit takes out the target emergency notification list from the database (S1302). Information (location registration area, business operator ID, message code) corresponding to the rescue requester displayed in the extracted emergency notification list is extracted (S1303). Then, registered mobile communication terminals having the same location registration area are extracted again from the database (S1304). This is because there is a possibility that the time has elapsed since the previous extraction of information and the position of the registered mobile communication terminal has changed.

  If the predetermined elapsed time for determining that the rescue requester has not been rescued yet is set short, the data registered in the emergency notification list may be used as it is. In other words, in the process under the situation setting where the possibility that the position of the mobile communication terminal registered in the emergency notification list is not changed, the process of step S1304 may not be performed.

  The emergency notification mail distribution control unit reproduces the emergency notification mail for redistribution (S1305). In the reproduced emergency notification mail, the transmission side location information and the emergency notification message code are written based on the information corresponding to the rescue requester displayed in the emergency notification list.

  The mail address of the registered mobile communication terminal to be redistributed obtained by re-extraction from the database is set as the destination address of the reproduced emergency notification mail (S1306).

  Then, the emergency notification list is updated with the newly extracted data of the registered mobile communication terminal, and a new identification number is assigned and stored in the database (S1307). The new identification number includes information indicating that it has been updated, and the updated year / month / day / hour / minute / second.

  When the process of step S1304 is omitted, it is preferable to keep the initial identification number so that the elapsed time from the initial emergency notification list generation time can be known. Then, when the emergency notification mail is re-delivered again, if the elapsed time exceeds a predetermined time, the process of step S1304 may be executed.

  The reproduced emergency notification mail is delivered to the set mail address (S1308).

  As described above, the completion of rescue is monitored in response to the rescue request. For this reason, it is possible to prevent a situation in which a rescue request is made but left without being rescued.

  Further, the emergency notification mail may be transmitted not only once but also many times until the emergency is canceled.

  In addition, the emergency notification server is configured to notify a public or private emergency reception center that specially accepts and responds to a rescue request when an emergency situation is not canceled even if an emergency notification mail is transmitted a predetermined number of times. May be.

  By the above operation, in this embodiment, the rescuer who has received the emergency notification mail can notify the rescue requester that the rescue has been completed and the emergency has been resolved. Then, the user of the mobile communication terminal who has received the emergency notification mail but has not been able to rescue immediately can know that the emergency has been resolved. Furthermore, if it is determined that the rescue requester has not been rescued even after the predetermined time has elapsed, an emergency notification mail is delivered again to a nearby mobile communication terminal to prevent the rescue requester from being left unattended. Can do.

Also in the present embodiment, it is possible to deliver an emergency notification mail according to the situation around the rescue requester who is experiencing an emergency, and efficiently notify the rescuer of the occurrence of the emergency.

(Modification of the fifth embodiment)
An embodiment for notifying that the emergency situation has been resolved using the rescue requester's mobile communication terminal will be described as a modification of the fifth embodiment.

  When an emergency operation is performed, the mobile communication terminal used in the modification of the fifth embodiment transmits an emergency notification mail and simultaneously performs an emergency notification operation in the mobile communication terminal. When emergency release is executed, an emergency release mail is transmitted, and at the same time, the emergency notification operation of the mobile communication terminal is stopped.

  The mobile communication terminal used in the modification of the fifth embodiment may be the mobile communication terminal 15 having the configuration described with reference to FIG. The difference is that the emergency notification mail generation function unit of the control unit 152 of the mobile communication terminal 15 includes an emergency notification instruction function unit and an emergency release function unit described below.

  The operation of the modified example of the fifth embodiment will be described with reference to FIGS.

  27 and 28 are flowcharts showing the operation of the rescue requester's portable communication terminal according to a modification of the fifth embodiment of the present invention. That is, it is a transmitting-side portable communication terminal in each embodiment described above.

  FIG. 27 shows the operation of the mobile communication terminal when the rescue requester performs an emergency operation, and FIG. 28 shows the operation of the mobile communication terminal when the emergency release operation is performed from the mobile communication terminal.

  First, an emergency operation will be described with reference to FIG.

  The operation from step S1400 to S1403 in FIG. 27 is the same as the operation from step S300 to S304 in the second embodiment described with reference to FIG. 9 in that an emergency notification mail is transmitted by executing the emergency operation. It is.

  Then, the emergency notification instruction function unit included in the emergency notification mail generation function unit of the control unit 152 of the mobile communication terminal 15 instructs the emergency notification operation execution function unit to execute the emergency notification operation (S1405).

  The emergency notification operation execution function unit that is instructed to execute the emergency notification operation instructs the input / output unit 151 to perform the predetermined emergency notification stored in the storage unit 155. In response to this instruction, an alarm or rescue request voice is output from the speaker of the input / output unit 151, and a message requesting rescue is also displayed on the display (S1406).

  By the above operation, if there is a person around the rescue requester, the emergency notification issued by the mobile communication terminal is noticed, and the rescue can be performed immediately.

  After the rescue as described above, if the rescuer does not have a portable communication terminal compatible with the emergency notification system, there is no means for notifying that the emergency requested by the emergency notification mail has been resolved. Therefore, by performing an emergency release operation from the mobile communication terminal, it is notified that the rescue requested by the emergency notification mail has been completed and the emergency has been resolved. This operation may be performed by a rescue requester or a rescuer.

  Assuming that the situation is serious and the rescue requester is not conscious, the rescue request message displayed on the above-mentioned display indicates the operation explanation for stopping the alarm broadcast from the mobile communication terminal. May be. By doing in this way, a rescuer performs operation for stopping the alert alert | reported from the portable communication terminal of the rescue requester.

  The flow shown in FIG. 28 is executed by an operation for stopping the alarm notified from the mobile communication terminal.

  The emergency release execution operation will be described with reference to FIG.

  The operation from step S1500 to S1503 in FIG. 28 is the same as the operation from step S1000 to S1003 in FIG. 22 in that an emergency release mail is transmitted by executing the emergency release operation. FIG. 22 is a flowchart showing an operation for executing emergency release of the mobile communication terminal according to the fifth embodiment.

  Then, the emergency release function unit included in the emergency notification mail generation function unit of the control unit 152 of the mobile communication terminal 15 instructs the emergency notification operation execution function unit to cancel the emergency notification operation (S1504).

  The emergency notification operation execution function unit instructed to cancel the emergency notification operation instructs the input / output unit 151 to stop the emergency notification being executed. In response to this instruction, the alarm / rescue request voice issued from the speaker of the input / output unit 151 is stopped, and the display message is erased (S1505).

  Note that the operation of the emergency notification server after the emergency release mail is transmitted and the operation of the mobile communication terminal that has received the emergency release mail are the same as those of the fifth embodiment, and thus the description thereof is omitted.

  By the above operation, the modified example of the fifth embodiment can receive rescue more reliably in a situation where there are people in the vicinity in addition to requesting rescue by an emergency notification mail. Become.

As mentioned above, although embodiment of this invention was explained in full detail, the system or apparatus which combined the separate characteristic contained in each embodiment how was included in the category of this invention.
