  FIG. 2 is a diagram schematically illustrating the disaster transmission table 400 stored in the connection information storage unit 107 of the telephone device 100.

  The disaster transmission table 400 includes a transmission destination base field 4001, a telephone number field 4002, and a priority field 4003. The destination base field 4001 registers the name of the destination base. The telephone number field 4002 registers the telephone number of the destination base. The priority field 4003 registers the priority order of the destination bases transmitted by the inter-base connection control unit 106, and the inter-base connection control part 106 transmits from the destination base having a high priority.

  The disaster transmission table 400 is a table generated in advance by the user, and the contents of the disaster transmission table 400 are different at each site.

  Here, with the record 4004 as an example, “A site” is registered as the destination site, “111-111-111” is registered as the telephone number, and “priority 1” is registered as the priority order. .

  FIG. 3 is a diagram schematically illustrating the inter-base connection information table 500 created by the inter-base connection control unit 106 of the telephone device 100.

  The inter-base connection information table 500 includes a disaster base field 5001, a disaster base telephone number field 5002, a master control base field 5003, a master control base telephone number field 5004, and a transmission route information field 5005. Furthermore, the transmission route information field 5005 is composed of subfields 5005-1 to 5005-n corresponding to the slave bases 1 to n.

  In the disaster base field 5001 and the disaster base telephone number field 5002, a disaster base name and a disaster base telephone number are set. In the master control base field 5003 and the master control base telephone number field 5004, master control information of the base name and telephone number that received the inter-base network request signal is set. In the subfields 5005-1 to 5005-n in the transmission route information field 5005, the telephone number of the slave base is set as the transmission route. Here, the transmission route means a call route that is formed by connecting each base in order from the master control base and is formed in a daisy chain. Subfield 5005-1 → subfield 5005-2 →. Calls are made in the order of subfields 5005-n.

  Here, taking the record 5006 as an example, in the record 5006, “A site” is set as the disaster base, “111-111-111” is set as the telephone number of the disaster base, and the master control base and the master control base phone number are set. , “B base” and “222-222-222” are set, respectively. Furthermore, as a slave base of the transmission route information, a route “D base (333-333-33)” → “E base (444-444-444)” →... “N base (nnn-nnn-nnn)” Indicates that

  The inter-base connection information table 500 is generated by the telephone device 100 that has received the inter-base network request signal from the disaster base.

  Specifically, when the telephone device 100 receives the inter-base network request signal from the disaster-stricken base, the telephone device 100 refers to the caller information (or busy line information) included in the incoming call detected before the inter-base network request signal is received. Then, the telephone number of the caller included in the caller information is acquired and set in the disaster base telephone number field 5002. Then, the telephone device 100 refers to the destination base that matches the disaster base telephone number set in the disaster base telephone number field 5002 from the disaster transmission table 400, and sets the detected destination base in the disaster base field 5001.

  Next, the telephone device 100 sets the name and telephone number of its own base in the master control base field 5003 and the master control base telephone number field 5004 (that is, the self base is set as the master control base).

  Further, the telephone device 100 extracts the destination base excluding the disaster base set in the disaster base field 5001 and the telephone numbers of the destination base in the order of the numbers in the priority field 4003 from the transmission route information set in the own device. Set for each record at the slave base.

  In this embodiment, as the slave base of the transmission route information, the destination base based on the priority order of the disaster transmission table 400 is set as the slave base, but a base close to the self base not shown is set as a slave base in advance. You may register.

  When the telephone device 100 receives the inter-base network connection information, the contents of the disaster base field 5001, the disaster base telephone number field 5002, the master control base field 5003, and the master control base telephone number field 5004 are not changed. In the transmission route information field 5005, the subfield in which the local site is set is excluded, the subsequent subfield is overwritten from the subfield in which the local site is set, and the transmission route information field 5005 is updated.

  For example, if the local site is set in the subfield 5005-1, the contents of the subfield 5005-1 are deleted, and the contents after the subfield 5005-2 are sequentially overwritten in the subfield 5005-1.

  It should be noted that a plurality of disaster-affected sites field 5001, disaster-affected location telephone number field 5002, master control location field 5003, master control location phone number field 5004, and outgoing route information field 5005 in inter-site connection information table 500 may be set.

  FIG. 4 is an operation flowchart relating to the operation of the telephone device 100, and will be described with reference to FIGS. This flow starts when the telephone device 100 is powered on.

  When the telephone device 100 receives the prediction information about the occurrence of a disaster (S100, YES), the telephone device 100 refers to the priority field 4003 of the disaster transmission table 400, and starts from the record with the highest priority. The destination base and the telephone number in 4001 and the telephone number field 4002 are sequentially acquired and assigned to an available outside line (S101).

  Subsequently, the telephone device 100 captures a free outside line to which the destination base and the telephone number are assigned (S102), starts a general call timer (S103), and receives the destination base field 4001 and the telephone number acquired in S101. Simultaneous transmission to the base of the field 4002 is performed (S104). If there is no free outside line in S101, monitoring of the free outside line is continued. In addition, when the prediction information is received, all the outside lines in a call may be forcibly disconnected.

  When the telephone device 100 does not receive the disaster occurrence prediction information (S100, NO), the telephone device 100 monitors the detection of the disaster occurrence (S120). When the telephone device 100 detects the occurrence of a disaster (S120, YES), the processing of S101 to S104 is performed.

  After S104, the telephone device 100 monitors the response of the destination (S105).

  When a response from the call destination is detected (S105, YES), the telephone device 100 establishes a call and stops the general call timer started in S103 (S106). Further, the telephone device 100 disconnects the outgoing external line other than the responding destination (S107). Then, the telephone device 100 transmits the inter-base network request signal to the responding destination (S108), holds the external line to which the destination responded (S109), and ends the process.

  When the response of the call destination is not detected (S105, NO), the telephone device 100 monitors the expiration of the general call timer started in S103 (S110). If the simultaneous timer has expired (S110, NO), the telephone device 100 continues to monitor S105.

  When the simultaneous timer has expired (S110, YES), the telephone device 100 disconnects the outside line captured in S102 (S111), refers to the priority field 4003 of the disaster transmission table 400, and is assigned next in S101. The destination base field and the telephone number in the destination base field 4001 and the telephone number field 4002 are sequentially acquired from the record having a high value and assigned to an available outside line (S112), and the processes after S102 are performed again.

  When the occurrence of a disaster is not detected (S120, NO), the telephone device 100 monitors whether there is an incoming call (S121). When there is no incoming call (S121, NO), the processing after S100 is continued. When there is an incoming call (S121, YES), the telephone device 100 rings its own device and establishes a call (S122). Here, the establishment of the call may be established by the telephone device 100 responding automatically, or the call may be established by the response of the user who uses the telephone device 100. When the telephone call 100 is established, the telephone device 100 monitors whether or not the inter-base network request signal is received (S130). When the inter-base network request signal is received (S130, YES), the telephone device 100 performs an inter-base network request signal reception process (S200) described later. When the inter-base network request signal is not received (S130, NO), the telephone device 100 monitors whether or not the inter-base network control information is received (S140).

  When the inter-base network control information is received (S140, YES), the telephone device 100 performs an inter-base network control information reception process (S300) described later. When the inter-base network control information has not been received (S140, NO), the processing after S100 is performed again.

  FIG. 5 is a flowchart showing the operation when the telephone device 100 of the present invention receives an inter-base network request signal from a telephone device at another base. This flow starts from a state in which the telephone device 100 has received the inter-base network request signal (YES in S130).

  The telephone device 100 holds the external line call that has received the inter-base network request signal (S201).

  After S201, the telephone device 100 refers to the priority field 4003 of the disaster transmission table 400 and identifies the record with the highest priority. After the identification, the destination base and the telephone number in the destination base field 4001 and the telephone number field 4002 are acquired (S202).

  Here, in S202, when the base that transmitted the inter-base network request signal is registered in the disaster transmission table 400, it is not included in the acquisition target.

  Subsequently, the telephone device 100 monitors whether or not an external line that can be captured is available (S203). It should be noted that one of the external lines other than the external line established in S122 may be forcibly disconnected from the currently connected external lines without monitoring the availability of the external lines that can be captured. If there is a vacant outside line (S203, YES), the telephone device 100 captures the outside line (S204), starts an outgoing call timer (S205), and makes a call to the destination base (S206). When there is no free outside line (S203, NO), the telephone device 100 continues to monitor S203.

  After S206, the telephone device 100 monitors the response of the destination (S207). When the call destination answers (S207, YES), the telephone device 100 establishes a call with the call destination and stops the call timer started in S205 (S208).

  Furthermore, the telephone device 100 creates inter-base network connection information (S209), and transmits the created inter-base network connection information to a call destination that is establishing a call (S210). Thereafter, the process is terminated while holding the external line call (S211).

  Note that the method of creating network connection information between bases in S209 is as described with reference to FIG.

  When the call destination does not respond (S207, NO), the telephone device 100 monitors the expiration of the timer started in S205 (S220). As a result of monitoring, when the calling timer expires (S220, YES), the next transmission destination is acquired from the disaster transmission table (S221), and S203 is performed again. If the call timer has expired (S220, NO), the monitoring in S207 is continued.

  Here, S221 acquires the destination base field 4001 and the telephone number field 4002 in the record with the highest priority other than the record acquired in S202.

  FIG. 6 is a flowchart showing an operation when the telephone device 100 of the present invention receives the inter-base network connection information generated by the telephone device at another base. This flow starts from a state in which the telephone device 100 has received the inter-base network control information (S140, YES).

  The telephone device 100 holds the external line call that has received the inter-base network control information (S301).

  After S301, the telephone device 100 refers to the subfield 5005-2 (slave base 2) of the inter-base connection information table 500, and acquires the destination base and the telephone number (S302). Here, when only the local site is set in the subfield of the inter-base connection information table 500, it is determined that there is no next destination (S303, YES), and S313 to S314 are performed.

  When it is determined that there is a next call destination (S303, NO), the telephone device 100 monitors whether or not an external line that can be captured is available (S304). Note that any external line other than the external line established in S122 may be forcibly disconnected without monitoring the availability of the external line that can be captured.

  If there is a free outside line (S304, YES), the telephone device 100 captures the outside line (S305), starts a call timer for outgoing calls (S306), and makes a call to the destination base (S307). If there is no free outside line (S304, NO), the telephone device 100 continues to monitor S304.

  After S307, the telephone device 100 monitors the response of the callee (S308). When the destination responds (S308, YES), the telephone device 100 stops the call timer started in S306 (S309).

  Subsequently, the telephone device 100 updates the inter-base network connection information (S310), and transmits the inter-base network connection information (S311). Thereafter, the telephone device 100 holds the transmitted external line (S312). Note that the method for updating the inter-base network connection information in S310 is as described with reference to FIG.

  When the destination does not respond (S308, NO), the telephone device 100 monitors the expiration of the timer started in S306 (S320). If the call timer has expired as a result of the monitoring (S320, YES), the telephone device 100 refers to the subfield 5005-3 (slave base 3) of the inter-base connection information table 500 to acquire the call destination (S321), S304 is performed again. In S321, if there is no next destination in the subfield of the base connection information table 500, the next destination is acquired again by returning to the top of the subfield (subfield 5005-2 in this embodiment). If the call timer has expired (NO at S320), the monitoring at S308 is continued.

  After S312, the telephone device 100 monitors whether the disaster-affected site and its own site (own device) are connected (S313). As a result of monitoring, when connected (S313, YES), the telephone device 100 disconnects the connection outside line (S314). If not connected (S313, NO), the process ends.

  The embodiment of the present invention has been described above.

  In the present embodiment, when the disaster occurrence prediction / detection unit 105 of the telephone device 100 receives prediction information of disaster occurrence or detects a disaster occurrence, the inter-base connection control unit 106 is stored in the connection information storage unit 107. A call is sent to a base registered in the disaster sending table 400. An inter-base network request signal is transmitted in response to the call destination, the outgoing line is held, and the inter-base connection control unit 106 of the telephone device 100 further receives the inter-base network request signal or the inter-base network control information. When received, the information is transmitted to another base set in the disaster transmission table 400 stored in the connection information storage unit 107 or the inter-base connection information table 500 included in the inter-base network control information. Based on the response of the other site, the inter-base connection information table 500 is newly created or updated, transmitted to the responding site, and the transmitted external line is held. Furthermore, when the disaster-affected site and the local site are connected, the outside line is disconnected.
