Description

  The present invention relates to a safety confirmation system using an IP (Internet Protocol) network system.

  In everyday life, people may be hit by large-scale accidents such as natural disasters such as typhoons and earthquakes, as well as explosions and fires. When such a disaster occurs, not only business communication but also communication for confirming the safety of the disaster victim is frequently performed. For example, the following methods are known as safety communication methods. In other words, the disaster victims individually use their mobile phones or the like to make calls to family members, acquaintances, etc., and inform their safety by voice calls. On the other hand, when confirming the safety of a victim from a family member or an acquaintance, the telephone of the family member or an acquaintance is sent to a mobile phone owned by the disaster victim or a fixed telephone set at the workplace, and a safety inquiry is made by voice call.

  However, when the disaster victims themselves and their family members and acquaintances communicate with each other by voice calls using telephones, communication traffic immediately increases immediately after the disaster occurs, and the public communication network is congested in a short time. In many cases, the result is a loss of communication. Such a state is extremely undesirable because it causes a great psychological burden on the victim and their family members and acquaintances, as well as a great deal of damage to other various communications.

  Therefore, for example, in an office or office building, an on-site PHS (Personal Handyphone System) is used to send an emergency notification message from the administrator's terminal to each terminal owned by the employee. There has been proposed a method in which an administrator confirms the safety of each employee by returning a response message from his / her terminal (see, for example, Patent Document 1).

JP 2007-124607 A

  However, since PHS is a Japanese original standard, the safety confirmation system using the local PHS cannot be widely used outside the country, and there is a problem that it lacks versatility.

  The present invention has been made paying attention to the above circumstances, and an object thereof is to provide a highly versatile safety confirmation system.

  In order to solve the above problems, a first aspect of the present invention is to connect a plurality of base stations to an IP (Internet Protocol) telephony server via a LAN (Local Area Network), and to connect the plurality of base stations. An IP network system in which the portable terminal can be connected via a wireless line, and a safety server, a data master server, and a client terminal connected to the IP network system via the LAN. And the said notification information transmitted from the said client terminal according to an administrator's input operation is received by the safety server via the said LAN, and the message showing this received notification information is prescribed | regulated by an IP network system. According to the communication protocol, the information is transferred from the safety server to the IP telephony server via the LAN, and transmitted from the IP telephony server to the plurality of mobile terminals. In addition, after sending the message, a response message returned from the mobile terminal is received by the safety server via the IP telephony server and the LAN, and the received response message is received from the safety server via the LAN. The information is transferred to the data master server and stored as information representing the safety confirmation result.

  According to a second aspect of the present invention, as means for transmitting the notification information, a voice message representing the notification information is transferred from the safety server to the IP telephony server via the LAN, and the plurality of portable terminals is transferred from the IP telephony server. Means for sending a broadcast message, means for specifying a portable terminal that does not send back a response message based on whether or not a response message has been received from the portable terminal after the broadcast transmission of the voice message, and a character representing the notification information Means for transferring a message from the safety server to the IP telephony server via the LAN and transmitting the message from the IP telephony server to the specified mobile terminal.

  According to a third aspect of the present invention, as a means for transmitting the notification information, a roaming mobile terminal among mobile terminals that do not return the response message after broadcast transmission of the voice message or after transmission of the text message is provided. A character message representing the notification information is transferred to a roaming-destination safety server that manages the specified roaming portable terminal, and the character message is transmitted to the roaming portable terminal. And a means.

  According to the first aspect, transmission of notification information for safety confirmation to the mobile terminal and reception of a response message from the mobile terminal can be performed using the IP network system. For this reason, for example, a highly versatile safety confirmation system can be provided as compared with the case of using a highly dedicated network such as PHS.

  According to the second aspect, when the notification information is first notified by a voice message and the portable terminal does not respond to the notification by the voice message, the same notification information is sent to the non-responsive portable terminal as a text message. Sent by. For this reason, it becomes possible to transmit notification information in two steps according to the state of the mobile terminal, thereby reducing notification omissions.

  According to the third aspect, when there is an unresponsive portable terminal, the roaming portable terminal is identified, and the character of the notification information is sent to the safety server in the service area where the roaming portable terminal is located. The message is transferred and a notification is made. For this reason, it becomes possible to further reduce the notification omission.

The IP network system 1 includes an IP telephony server 11 as a core. Then, a SIP (Session Initiation Protocol) compatible terminal 12 and a plurality of base stations 131 to 13n are connected to the IP telephony server 11 via a LAN (Local Area Network) 2, and wirelessly connected to the base stations 131 to 13n. The portable terminals TM1 to TMn can be connected via a line.

  In the IP network system, as communication protocols, SIP for voice communication and UDP TCP / IP (User Datagram Protocol Transmission Control Protocol / Internet Protocol) for communication with devices other than SIP compatible terminals, TCP Above, HTTP (Hypertext Transfer Protocol) that transmits information files in packets and SMTP (Simple Mail Transfer Protocol) that transmits electronic mail are used.

  The mobile terminals TM1 to TMn are composed of mobile phones, smartphones, and tablet terminals, and a numeric keypad 61 and a situation response button 62 are provided on the operation panel, for example, as shown in FIG. Among these, the numeric keypad 61 is used when the user inputs a response message indicating his / her situation when notification information for safety confirmation is received. On the other hand, the situation response button 62 is used when returning a pre-made response message corresponding to the current situation when the user cannot input a response message using the numeric keypad 61. For example, a wireless LAN is used as the wireless line.

  By the way, the safety server 3, the data master server 4, and the client terminal 5 are connected to the LAN 2. The client terminal 5 is a stationary personal computer, and is used by an administrator to input notification information for confirming safety. FIG. 3 shows an example of a safety confirmation event selection menu displayed when the notification information is input, and a safety confirmation start button 52.

  The data master server 4 is composed of a Web server, periodically monitors the issuance of notification information for safety confirmation and instructs the safety server 3 to transmit the notification information, and response messages from the mobile terminals TM1 to TMn. Is received from the safety server 3, and the response message is stored in the database as information indicating the safety confirmation result.

  The safety server 3 includes a server computer or a personal computer, and includes a control unit 31, a database 32, and a communication interface unit 33 as shown in FIG.

  The communication interface unit 33 transmits / receives data to / from the client terminal 5, the data master server 4, and the plurality of portable terminals TM 1 to TMn accommodated in the IP network system 1 via the LAN 2. At this time, SIP is used when voice data is transmitted and received, and SMTP is used when electronic mail is transmitted and received.

  The database 32 is provided with a notification information storage unit 321 and a safety confirmation result storage unit 322. The notification information storage unit 321 is used to temporarily store notification information for safety confirmation transferred from the data master server 4. The safety confirmation result storage unit 322 is used to store a response message returned from the mobile terminals TM1 to TMn after the notification information is transmitted as information indicating a safety confirmation result.

  The control unit 31 includes a central control unit (CPU: Central Processing Unit). As control functions necessary for realizing the present embodiment, a notification information registration acceptance control unit 311, a broadcast service control unit 312, a character message A service control unit 313, a safety confirmation service control unit 314, and a roaming destination notification control unit 315 are provided. These control functions are realized by causing the CPU to execute a program stored in a program memory (not shown).

  The notification information registration acceptance control unit 311 transfers the notification information for safety confirmation transmitted from the client terminal 5 as voice guidance to the data master server 4 and receives the notification information registration request from the data master server 4. In this case, a process for storing the notification information in the notification information storage unit 321 is performed.

  When new notification information is stored in the notification information storage unit 321, the broadcast service control unit 312 transmits an IP message of the notification information to the notification target mobile terminals TM <b> 1 to TMn in order to perform broadcast transmission. A process of transferring to the telephony server 11 is performed.

  The character message service control unit 313 identifies a non-response portable terminal that does not return a response message after the broadcast transmission of the voice message is completed, and transmits the character message of the notification information to the portable terminal by e-mail. I do.

  The safety confirmation service control unit 314 receives the response message returned from the notification target mobile terminals TM1 to TMn in response to the transmission of the notification information by the broadcast service control unit 312 and the character message service control unit 313. And the said response message is memorize | stored in the safety confirmation result memory | storage part 322, and the process which transfers to the data master server 4 and memorize | stores it in a database is performed.

  The roaming destination notification control unit 315 specifies a mobile terminal that is unable to transmit the broadcast voice message or the text message because of the roaming among the notification target mobile terminals TM1 to TMn. And the process which transfers the said character message with respect to the safety confirmation system used as the roaming destination of the said portable terminal is performed.

  The roaming destination may be, for example, an IP network system of a branch office, another office, or an affiliated company. The roaming destination safety confirmation system has the same configuration as the above-described roaming source safety confirmation system.

  When the roaming safety server receives the text message from the roaming safety server 3, the roaming safety server performs a process of transmitting the text message to the roaming mobile terminal by e-mail. In addition, when a response message is returned from the roaming mobile terminal, the roaming safety server transfers the response message to the roaming safety server 3 and the data master server 4 and stores them in the database. I do.

(Operation)
Next, the safety confirmation operation by the system configured as described above will be described focusing on the operation of the safety server 3.

(1) Safety Confirmation Operation for Mobile Terminals Existing in Service Area of IP Network System 1 FIG. 5 is a diagram showing a processing procedure and processing contents of a safety confirmation operation for mobile terminals existing in the service area of IP network system 1. .

  When a disaster occurs, the administrator activates a function for notifying safety confirmation in the client terminal 5 (step (1)). As a result, for example, a safety confirmation event menu screen is downloaded from the safety server 3 to the client terminal 5 and displayed on the display of the client terminal 5. The menu screen for the safety confirmation event may be stored in the client terminal 5 in advance.

In this state, when the administrator selects, for example, “earthquake occurrence” from the menu of the safety confirmation event, notification information by voice guidance corresponding to “earthquake occurrence” (hereinafter, notification) (Referred to as information voice message) (step (2)). For example,
“Earthquake occurred. Please select the current situation immediately. Enter“ 1 ”for safety and…“ 3 ”for serious injury. Please hang up to cancel. "
Is created. This voice message is transmitted from the client terminal 5 to the safety server 3 via the LAN 2 and transferred from the safety server 3 to the data master server 4 together with a safety notification registration request (step (3)).

  When the data master server 4 receives the safety notification registration request, the data master server 4 stores the voice message queue of the notification information received together with the registration request in the safety confirmation queue 421 of the database (DB). The data master server 4 regularly monitors the safety queue 421 for storing a new safety confirmation queue by the safety monitoring service control unit 41 (step (4)). When the queue is saved, the voice message of the corresponding notification information is read out and transmitted to the safety server 3 as the notification information queue (step (5)).

  When receiving the notification information queue from the data master server 4, the safety server 3 stores the received notification information queue in the notification information storage unit 321. The safety server 3 periodically monitors whether the notification information queue is issued by the safety confirmation service control unit 314 (step (6)). When the notification information queue is stored in the notification information storage unit 321, the notification information queue is read out and stored in the broadcast notification queue and the character message notification queue (step (7)). ).

  In the safety server 3, the broadcast service control unit 312 monitors whether or not a queue is stored in the broadcast notification queue (step (8)). When the issuance of a broadcast notification queue is detected, a voice message of notification information is transmitted to the IP telephony server 11 via the LAN 2 (step (9)). The IP telephony server 11 broadcasts the voice message of the notification information received from the safety server 3 to the mobile terminals TM1 to TMn via the base stations 131 to 13n according to SIP (step (10)).

  On the other hand, when the user of the portable terminals TM1 to TMn receives the voice message of the notification information in a situation where a safety confirmation response is possible, the user presses the key corresponding to his / her current situation on the numeric keypad 61. Then, a response message corresponding to the operated numeric keypad is returned from the portable terminals TM1 to TMn (step (11)). The returned response message is sent to the IP telephony server 11 via any of the base stations 131 to 13n, and transferred from the IP telephony server 11 to the safety server 3 via the LAN 2 (step (12)). .

  When receiving the response message, the safety server 3 stores the response message in the character message history storage unit under the control of the character message service control unit 313 (step (13)). In addition, the safety server 3 monitors the reception of the response message addressed to its own server by the safety confirmation service control unit 314 (step (14)). When a response message addressed to the own server is received, the response message is stored in the safety confirmation result storage unit 322 in the database 32 and transferred to the data master server 4 (step (15)). The data master server 4 stores the response message transferred from the safety server 3 in the safety confirmation result storage unit 422 of the database.

  Prior to storing the received response message, the safety server 3 determines whether the key number represented by the response message is correct. If it is a key other than the selection target, it is determined as an erroneous operation, and a voice guidance message to that effect, for example, “input error” is transmitted to the return-source mobile terminal via the IP telephony server 11, and again. Prompt for selection operation.

On the other hand, if the key represented by the received response message is a key in the selection target range, it is determined that the correct response message has been received, and a voice guidance message indicating that the response message has been received, for example, “safety confirmation” Please hang up the phone. "
Is transmitted to the mobile terminal that is the reply source via the IP telephony server 11. When correct response messages are received from all the mobile terminals TM1 to TMn, the corresponding queue stored in the character message notification queue is deleted.

  On the other hand, it is assumed that a user who has received the voice message of the notification information includes a user who is difficult to hear the voice message due to injury or ambient noise. In this case, the user presses the situation response button 62. Then, a response impossible message corresponding to the operated status response button 62 is returned from the portable terminals TM1 to TMn (step (11)). The returned response impossible message is sent to the IP telephony server 11 via any of the base stations 131 to 13n, and transferred from the IP telephony server 11 to the safety server 3 via the LAN 2 (step (12)). ).

  When the safety server 3 receives the response impossible message, the text message service control unit 313 determines whether an untransmitted queue is stored in the text message notification queue (step (8)). If there is an unsent queue, a text message of notification information is generated, and the text message is transmitted to the portable terminal that is the reply source of the response impossible message via the IP network system 1 by electronic mail.

  The safety server 3 determines whether or not there is a non-response portable terminal that does not return either a response message or a non-response message even after a predetermined time has elapsed after the transmission of the voice message of the notification information. And when there is this non-response portable terminal, the character message of the notification information is generated for the non-response portable terminal as well as the case of the portable terminal that has returned the non-response message. A text message is transmitted by e-mail to the non-response portable terminal via the IP network system 1. When the transmission of the character message is completed, the queue stored in the character message waiting queue is deleted.

  The text message of the notification information is received by the destination portable terminal and displayed on the display by the user's display operation. In this state, when the user operates a key corresponding to his / her situation, the response message is sent back to the safety server 3 and stored in the safety confirmation result storage unit 322 as in the case of the response to the voice message described above. At the same time, the response message is also stored in the safety confirmation result storage unit 422 of the data master server 4.

(2) Safety Confirmation Operation for Mobile Terminal While Roaming FIGS. 6A and 6B are diagrams illustrating a processing procedure and processing contents of a safety confirmation operation for a mobile terminal during roaming. In the figure, the same processing units as those in FIG.

  The safety server 3 determines whether or not there is a non-response portable terminal that does not return either a response message or a non-response message even after a predetermined time has elapsed after transmission of the voice message of the notification information. And when there exists this non-response portable terminal, it is determined whether the said non-response portable terminal is roaming.

  When the roaming portable terminal TMi is identified by the above determination, the safety server 30 connected to the IP network system covering the service area where the roaming portable terminal TMi exists (hereinafter referred to as a roaming destination safety server). The character message queue of the notification information is transferred to (Step A). Note that information transmission between the roaming source and the roaming destination safety server is performed via a public network or the Internet.

  The roaming destination safety server 30 stores the character message queue of the transferred notification information in the character message notification queue. In addition, the safety server 30 at the roaming destination determines whether the queue is stored in the character message notification waiting queue by the character message service control unit 313 (step B). If the queue is stored, the character message of the notification information is transferred to the IP network system 1 by e-mail (step C) and transmitted from the IP network system 1 to the roaming mobile terminal TMi (step D). . When the transmission of the character message is completed, the queue stored in the character message notification queue is deleted.

  The e-mail of the text message is received by the destination mobile terminal TMi and displayed on the display by the user's display operation. In this state, when the user operates a key corresponding to his / her situation, a response message is returned to the IP network system 1 (step E) and transferred from the IP network system 1 to the safety server 30 (step F).

  When receiving the response message, the safety server 30 stores the response message in the character message history storage unit under the control of the character message service control unit 313 (step G). The safety server 30 monitors the reception of the response message by the safety confirmation service control unit 314 (step H). When the response message is received, the response message is transferred to the roaming safety server 3 and the data master server 4 (step I).

  Upon receiving the response message transferred from the roaming safety server 30, the safety server 3 stores the response message in the safety confirmation result storage unit 322 in the database 32. The data master server 4 also stores the response message transferred from the roaming safety server 30 in the safety confirmation result storage unit 422.

(effect)
As described above in detail, in one embodiment, the safety server 3, the data master server 4, and the client terminal 5 are connected via the LAN 2 to the IP network system 1 that accommodates the mobile terminals TM1 to TMn with the IP telephony server 11 as the core. is doing. And the notification information for safety confirmation transmitted from the client terminal 5 is transmitted from the safety server 3 to the portable terminals TM1 to TMn via the IP telephony server 11, and after the notification information is transmitted, the portable terminals TM1 to TMn are transmitted. Is received by the safety server 3 via the IP telephony server 11, and the received response message is transferred from the safety server 3 to the data master server 4 and stored as a safety confirmation result. I have to.
