  When the process is activated, the access terminal file 60 is referred to and whether or not there is a new writing from the previous confirmation time is confirmed (S201). The previous confirmation time is obtained from the previous confirmation time with reference to the environment definition file 61.

  It is determined whether or not there is new writing (S202). If there is no new writing (NO in S202), the process waits until there is new writing.

  If there is new writing (YES in S202), the process proceeds from the loop start end (S203) to the in-loop processing. In this loop, the access terminal file 60 is referred to, and the “terminal ID / MAC address / phone number / usage start flag / usage end flag” is delivered to activate the connection management function 66 (S204). In S204, the delivered time and the data 102 of “terminal ID, MAC address, (telephone number), flag (use start / end)” are provided to the connection management function 66 for processing of the connection management function 66 (S205). Used.

  The processing in the loop (S204) is repeated until there is no new connection terminal, and when there is no new connection terminal in the access terminal file 60 being referred to, the loop end is reached (S206). Then, the confirmation time is recorded in the environment definition file 61 (S207), and this process ends.

  <Processing Procedure of Connection Management Function 66 of Disaster Processing Server 20>

  FIG. 19 shows a processing procedure of the connection management function 66 in the disaster processing server 20.

  This processing procedure is an example of the emergency support program of the present disclosure. In this processing procedure, “terminal ID, MAC address, (telephone number), and flag (use start / end)” are received from the user management function 64 of the disaster processing server 20 to start processing.

  Whether the use start flag or the use end flag is confirmed by starting the process is checked (S301). If it is a use end flag (end flag in S301), the process ends. In this case, the connection management database is searched with the terminal ID, the information specified by the use end flag is deleted (S302), and the process ends.

  If it is a use start flag (start flag in S301), the process proceeds from the loop start end (S303) to the in-loop processing (S303 to S306). In-loop processing is repeated for the number of floor routers. In this in-loop processing, the router in the floor router list 104 is accessed, and the terminal ID connection request is confirmed by referring to the router log (S304). This terminal ID connection request is searched from a range in which the time information is given a width corresponding to the activation cycle of the user management function (server function) 64, and is searched from the terminal ID and the MAC address. In referring to the router log 88, the router IP, router name, and log file path are acquired from the floor router list 106.

  After sequentially confirming the connection request for the target terminal ID and repeating the confirmation for the number of floor routers, if there is a connection request (there is a connection request in S304), the connection destination router name 106 is acquired (S305), and the loop It reaches the end (S306).

  After exiting this loop, the connection log 92 of the DNS / DHCP server 22 is referred to obtain the IP address 108 used by the target terminal ID (S307). In this case, when the DNS / DHCP server 22 is not used, information is acquired from the IP address list corresponding to the terminal ID.

  The router name 106 acquired in S305 and the IP address 108 acquired in S307 are notified to S308. “Terminal ID / MAC address / IP address / router name (destination) / phone number” is written in the connection management DB 24 (S308), and this process is terminated.

  <Processing procedure of connection destination search function 68 of disaster processing server 20>

  FIG. 20 shows a processing procedure of the connection destination search function 68 in the disaster processing server 20.

  This processing procedure is an example of the emergency support program of the present disclosure. In this processing procedure, the process is started by a start process (S401) based on a monitor message trigger from the monitoring server 18. When this activation is started, a loop end (S402) is entered, and the processing in the loop is repeated by the number of data in the connection management DB 24. In this case, data is extracted line by line from the connection management DB 24 (S403). The emergency gathering location information file 62 corresponding to the router name (connection destination) is referred to, and the emergency gathering location information file 62 is used to call the emergency gathering location (router name / emergency gathering location / emergency gathering location router name / location). (Code) 110 is allocated (S404).

  The monitoring information DB 59 is accessed to check whether or not the emergency meeting place router can communicate (S405). If communication is impossible (communication impossible in S405), the emergency meeting place information file 62 is accessed, and the nearby emergency meeting place 110 is searched again from the place code (S406).

  If communication is possible (communication is possible in S405), the monitoring information DB 59 is accessed to check whether or not the router with the router name (connection destination) can communicate (S407). If communication is possible (communication is possible in S407), the emergency meeting place name / IP address (terminal) is handed over to the notification function 70 and the notification function 70 is activated (S408).

  If communication is not possible (communication impossible in S407), the emergency meeting place name / phone number is handed over to the notification function 70 and the notification function 70 is activated (S409).

  When the notification function 70 is activated, the information terminal 16 is notified based on the delivered emergency meeting place name / IP address, or the telephone number is notified based on the delivered emergency meeting place name / phone number. (S410).

  After the processing of S408, the loop end (S411) is reached and this processing is terminated.

  <Processing Procedure of Notification Function 70 of Disaster Processing Server 20>

  FIG. 21 shows a processing procedure of the notification function 70 in the disaster processing server 20.

  This processing procedure is an example of the emergency support program of the present disclosure. In this processing procedure, it is determined whether the delivered argument is an IP address or a telephone number (S501). If the argument is an IP address (IP address of S501), a message is sent to the terminal indicating the emergency gathering location using the IP address (S502).

  If the argument is a telephone number (the telephone number in S501), the IVR (Interactive Voice Response: voice / fax response function / telephone notification function) and an emergency meeting place for the user using the delivered telephone number. A message notification is made (S503). Based on this, the IVR process is executed (S504).

<Functions and configuration during normal times>

  22 and 23 show a configuration example of the emergency support system 2 during normal times.

  In normal times, as shown in FIG. 22, at the time of start-up, information on the routers 8-1, 8-2 and the information terminals 16-1, 16-2 from the information terminals 16-1, 16-2 to the disaster processing server 20; The user's contact phone number is provided. In this case, information on the routers 8-1 and 8-2, which are normally used by the information terminals 16-1 and 16-2, and information terminals 16-1 and 16-2 connected to the routers 8-1 and 8-2. Information that can be specified is provided. These pieces of information including the contact telephone number are transmitted from the user management function 64 to the connection management function 66 and stored in the connection management DB 24.

  Also, as shown in FIG. 23, the user management function 64 of the disaster processing server 20 generates a router log 88 of each router 8-1, 8-2 and a connection log 92 of the DNS / DHCP server 22 from the connection management function 66. Referenced. The acquired recording information is stored in the connection management DB 24. That is, in the normal connection management DB 24, as shown in FIG. 28A, the terminal ID, MAC address, IP address, user telephone number, and used router name of each information terminal 16 are stored.

<Functions and configuration at the time of disaster>

  24, 25, 26, and 27 show a configuration example of the emergency support system 2 when a disaster occurs.

  When a disaster occurs, the monitoring information DB of the monitoring server 18, the connection management DB 24, and the emergency meeting place information file 62 are referred to by the connection destination search function 68 of the disaster processing server 20 as shown in FIG.

  In this case, a disaster event has occurred, and the monitoring server 18 detects a trouble in a plurality of nodes and lines. In this case, the router 8-1 (router A) is not connectable. That is, the information terminal 16-1 connected to the router 8-1 is incapable of communication.

  Information on the movement destination cannot be notified to the information terminal 16-1 that has become unable to connect. Thus, as shown in FIG. 25, the IVR function of the connection destination search function 68 and the notification function 70 is used to notify the telephone number of a communication terminal such as the mobile phone 112 of the user staying on the floor 4-1. Thereby, the user can know the destination. When the user who knows the destination brings the information terminal 16-1 from the floor 4-1, and moves to the floor 6-2 as shown in FIG. 26, the information terminal 16-1 is connected to the router 10-2. Connect and use. That is, the user who has stayed on the floor 4-1 can also use the information terminal 16-1 for normal use as a disaster use terminal.

  On the other hand, since the router 8-2 can communicate, the destination of the information terminal 16-2 is notified to the information terminal 16-2 by the notification function 70 as shown in FIG. This destination is the floor 6-3, and the destination router 10-3 is designated. Therefore, as shown in FIG. 27, the user staying on the floor 4-2 brings the information terminal 16-2 removed from the router 8-2 and moves to the floor 6-3. The information terminal 16-2 can be connected to and used. That is, the information terminal 16-2 for normal use can be used as a disaster use terminal.

  When this disaster occurs, as shown in B of FIG. 28, the terminal ID, MAC address, user telephone number, and used router name stored in the connection management DB 24 are used.

  When a disaster occurs, the destination, that is, the evacuation destination is specified by the emergency gathering place information in the emergency gathering place information file 62. The emergency meeting place information file 62 shown in FIG. 29 shows the following instructions.

  (1) “> 1. Floor 6-1 (Router Z1 code: 11) Routers C, D, F, J, K, U, V” = Connect to routers C, D, F, J, K, U, V The movement destination of the information terminal 16 is the floor 6-1 and the connection destination is the router Z1 (router 10-1).

  (2) “×> 2. Floor 6-2 (Router Z2 code: 12) Router A, E, G, H, I, R, S, T” = Router A, E, G, H, I, R, The destination of the information terminal 16 connected to S and T is the floor 6-2, and the destination is the router Z2 (router 10-2).

  In this case, “x” in (2) indicates that the evacuation destination is defective.

  (3) “> 3. Floor 6-3 (Router Z3 code: 21) Routers B, L, M, Q” = The destination of the information terminal 16 connected to the routers B, L, M, Q is Floor 6 -3, and the connection destination is the router Z3 (router 10-3).

<Operation sequence during normal times>

  FIG. 30 is referred to regarding the operation sequence during normal times. FIG. 30 is an example of an operation sequence of the information terminal 16-1, the router 8-1 (router A), the DNS / DHCP server 22, the disaster processing server 20, and the connection management DB 24. These nodes correspond to the normal configuration shown in FIGS. 22 and 23 described above.

  In the information terminal 16-1, which is an example, the user management function 26 is executed (Process F1) when the use is started (S601). With the start of the process F1, user information input is requested from the information terminal 16-1 to the user (S602). User information input is confirmed by pressing the confirm button.

  After this user information is input, an IP address acquisition request is issued from the information terminal 16-1 to the router 8-1 (S603). The router 8-1 that has received this IP address acquisition request transfers the IP address acquisition request to the DNS / DHCP server 22 by executing the process F2 (S604). The DNS / DHCP server 22 executes terminal authentication and IP address issue processing F3, and transfers the IP address to the router 8-1 (S605). The router 8-1 transfers the received (processing F2) IP address to the information terminal 16-1, and the information terminal 16-1 acquires the IP address (S606).

  The information terminal 16-1 registers user information for writing the access terminal file 60. Information for registration is issued from the information terminal 16-1 (S607), and this information is transferred to the disaster processing server 20 via the process F4 of the router 8-1 (S608). In the disaster processing server 20, the write processing F5 of the access terminal file 60 is executed. The writing of the access terminal file 60 triggers the start of use. This write result is issued from the disaster processing server 20 to the router 8-1 (S609). This write result is notified to the information terminal 16-1 via the router 8-1 (processing F4) (S610).

  In the disaster processing server 20, the user management function 64 is activated by the writing of the access terminal file 60, and the process F6 is executed.

  The activation of the user management function 64 (S611) confirms the writing of the access terminal file 60 (S612). This process is executed every predetermined time, for example, every few minutes. If the access terminal file 60 is confirmed to be written, the connection management function 66 is activated (S613). In this case, if there is no writing, the process ends.

  When the connection management function 66 is activated, the router log 88-1 is referred to and information on the router 8-1 (router name, etc.) is confirmed from the terminal name (S614). In this process, the router log 88-1 is referred to the router 8-1 (S615), and the process information F7 of the router 8-1 notifies the disaster processing server 20 of the record information of the router 8-1 (S616). ).

  The disaster processing server 20 refers to the connection log and confirms the use of the terminal by the terminal name and the IP address (S617). In this process, the connection log 92 is referred to the DNS / DHCP server 22 (S618), and notification of terminal usage information is received by the process F8 of the DNS / DHCP server 22 (S619).

  The disaster processing server 20 that has acquired the user information writes the information in the connection management DB 24 (S620). In this case, the disaster processing server 20 notifies the acquired user information to the connection management DB 24 (S621), and the connection management DB 24 executes the write process F9 and notifies the disaster processing server 20 of the notification result ( S622).

  The processes F1 to F9 of the information terminal 16-1, the router 8-1, the disaster processing server 20, the DNS / DHCP server 22, and the connection management DB 24 are automatically executed.

  When the use of the information terminal 16-1 ends, the end of terminal use is notified to the router 8-1 (S623), and the end of use of the terminal is transferred to the disaster processing server 20 by the process F10 of the router 8-1. (S624). In the disaster processing server 20, a write process F11 of the end of use of the access terminal file 60 is executed. The end of the process F11 is notified to the router 8-1 (S625), and is transferred from the router 8-1 to the information terminal 16-1 (S626).

  Receiving the terminal use end, the disaster processing server 20 activates the user management function 64 (process F12), and confirms writing of the access terminal file 60 (S627). This processing is performed periodically, and is executed every few minutes as described above. When there is a write, the connection management function 66 is activated (S628), and when there is no write, the process ends.

  User information is deleted when terminal use ends. In this case, the connection management DB 24 is instructed to delete the user information from the disaster processing server 20 (S629). The connection management DB 24 executes a user information deletion process F13. The result of this process F13 is notified to the disaster processing server 20 (S630).

  <Operation sequence 1 when a disaster occurs>

  The operation sequence 1 at the time of disaster occurrence will be described with reference to FIG. FIG. 31 is an example of an operation sequence of the information terminal 16-1, the router 8-1 (router A), the monitoring server 18, the disaster processing server 20, the connection management DB 24, and the router 10-2. These nodes correspond to the configuration at the time of disaster occurrence in FIGS. 24, 25, and 26 described above.

  Upon detection of the occurrence of a disaster in the monitoring server 18, the monitoring server 18 executes process F14. This process F14 is processed by remote execution. This remote execution is automatically executed when the monitoring server 18 detects a message indicating the occurrence of a disaster.

  The occurrence of the disaster is notified from the monitoring server 18 to the disaster processing server 20 (S631). Upon receiving this notification, the disaster processing server 20 executes activation of the connection destination search function 68 (process F15) (S632), and instructs the connection management DB 24 to search for a terminal being used (S633). In the connection management DB 24, a user search process F16 is executed. In this search process F16, a user in use is searched.

  The disaster processing server 20 receives an inquiry of emergency meeting place information from the connection management DB 24, and searches for an emergency meeting place from the use router (S634). Confirmation of the emergency gathering destination router [SNMP (Simple Network Management Protocol) transmission] is performed to the router 10-2 at the emergency gathering destination (movement destination) (S635). The router 10-2 that has received the SNMP transmission executes an SNMP reply process F17 and sends an SNMP reply to the disaster processing server 20 (S636).

  As a result, the disaster processing server 20 confirms the use router (SNMP transmission) with respect to the router 8-1 as the use router (S637). In this case, since the router 8-1 (router A) is in a state where communication is impossible due to the influence of the disaster, the reply cannot be made. On the other hand, the disaster processing server 20 performs several retries and confirms that the router 8-1 cannot communicate.

  The disaster processing server 20 activates the notification function 70 when the router 8-1 cannot communicate. The user telephone number is called by the IVR function included in the notification function 70, and the emergency meeting place is notified (S638). The user can receive the emergency meeting place through the mobile phone 112.

  <Operation sequence 2 when a disaster occurs>

  FIG. 32 will be referred to for the operation sequence 2 when a disaster occurs. FIG. 32 is an example of an operation sequence of the information terminal 16-2, the router 8-2 (router B), the monitoring server 18, the disaster processing server 20, the connection management DB 24, and the router 10-3. These nodes correspond to the configuration at the time of disaster occurrence shown in FIGS. 26 and 27 described above.

  In the operation sequence 2 at the time of disaster occurrence, on the router 8-2 (router B) side, S631 is a message trigger execution, that is, when a message is detected, it is automatically executed, and the processing from S632 to S636 is the same. I will omit the explanation.

  In the confirmation of the use router (SNMP transmission), the disaster processing server 20 performs SNMP transmission to the router 8-2 (S640). The router 8-2 executes the SNMP reply process F18 and sends an SNMP reply to the disaster processing server 20 (S641). Since the router 8-2 can communicate by this SNMP reply, the disaster processing server 20 notifies the information terminal 16-2 of the emergency meeting place by a message (S642). As a result, the information terminal 16-2 can receive the emergency meeting place. Therefore, the user can bring the information terminal 16-2 and move to a predetermined floor which is an emergency meeting place.
