Description

  The present invention receives an emergency information from an external emergency information sending device permitted by a telephone user in advance, and can immediately send emergency information to a telephone terminal generally used on a normal telephone immediately ( The present invention also relates to a telephone device with an emergency emergency information transmission function and an emergency information transmission server device (hereinafter also simply referred to as a transmission server) used in the emergency emergency notification system.

  For emergency calls, dedicated equipment that cannot be used for normal calls is usually arranged. For example, in the earthquake detection notification device, when the Japan Meteorological Agency detects the first initial earthquake, there is a device that transmits it to an emergency emergency notification device registered in advance to notify the next earthquake. Others broadcast emergency information all at once by telephone using the IP network.

  Dedicated equipment for earthquakes, fires, and other emergency emergency reports is not used except in an emergency and becomes an idle facility, which is not efficient. Also, for emergency information broadcasted simultaneously over the telephone using the IP network, the sending device is selected in advance at the phone terminal, and the sending device interrupts the normal call of the phone terminal at the time of emergency call and gives priority to emergency information Was not sent out.

  In order to solve the above-described problems, an emergency emergency call system according to the present invention includes at least one transmission server device that receives emergency information from an external emergency information transmission device and transmits the emergency information via a communication network, and At least one normal call mediation server device that mediates a call via a communication network, the emergency transmission server device, and a plurality of telephone terminals connected to the normal call mediation server device via a communication network, When the telephone terminal receives emergency information from the emergency transmission server device, the telephone terminal broadcasts the emergency information with priority.

  Furthermore, the telephone device with an emergency emergency information transmission function of the present invention includes an identification information storage unit that stores in advance identification information of a transmission server device that transmits emergency information, and the call is received by the identification information storage unit when a call is received. A collation unit for collating whether the call is from the transmission server device stored in the server, and when the collation unit determines that the call is from the transmission server device, priority is given to emergency information from the transmission server device It is characterized by broadcasting.

  According to the present invention, an emergency emergency call can be preferentially broadcast by interrupting a call in an emergency using a telephone used for a normal call (hereinafter also referred to as a telephone terminal or a telephone terminal device). For this reason, it is possible to eliminate the need for dedicated equipment for emergency emergency calls that are not normally used. In addition, there may be a plurality of sending devices, and at the discretion of the user of the telephone terminal, by selecting which sending device receives the emergency call, only the various types of emergency calls required by the user can be sent. Can be received. The sending device also determines whether the user needs the information, such as the location of the telephone terminal and the attribute information such as the age and organization of the registered user who is used exclusively. By adopting a mechanism for selecting and sending, high convenience can be provided.

  The emergency emergency call system according to the present invention mediates a normal call via a communication network with at least one transmission server device that receives emergency information from an external emergency information transmission device and transmits the emergency information via a communication network. At least one normal call mediation server device, the emergency transmission server device, and a plurality of telephone terminals connected to the normal call mediation server device via a communication network, the telephone terminal being the emergency transmission server When emergency information is received from the device, the emergency information is broadcast with priority.

  The transmission server device of the present invention includes an identification information storage unit that stores in advance identification information of a telephone terminal, an emergency information content storage unit that stores in advance the contents of a report for emergency information, and emergency information from an external emergency information transmission device And an emergency information transmission processing unit for transmitting the contents of the notification stored in the emergency information content storage unit to the telephone terminal stored in the identification information storage unit.

  The telephone device with an emergency emergency information transmission function of the present invention includes an identification information storage unit that stores in advance identification information of a transmission server device that transmits emergency information, and the call stored in the identification information storage unit when a call is received. A collation unit that collates whether the call originates from the transmission server device, and when the collation unit determines that the call is from the transmission server device, the emergency information from the transmission server device is preferentially broadcast. To do.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic block diagram showing the entire emergency emergency call system. In FIG. 1, an emergency emergency call system 10 includes an emergency information transmission server device (transmission server) 14 connected to a communication network 18, a normal call mediation server device (mediation server) 16, and a plurality of telephone terminal devices. 20 (in the embodiment, two telephone terminal devices 20A and 20B are taken as an example).

  The sending server 14 may be connected to an external emergency information sending device 12 such as an earthquake detection reporting device, or may start sending an emergency emergency report directly from a man-machine interface comprising a monitor screen and a keyboard. Focusing on the specific telephone terminal 20A, the telephone terminal is connected to a communication network for a telephone call which is a normal purpose of use, and executes a normal telephone call pre-registration process 24 in order to clarify the location to the mediation server 16. As a result, a state in which a call to another telephone terminal 20B that has been registered in the same manner from the mediation server 16 or a call request from the other telephone terminal 20B is received via the mediation server 14 by the call control 28 at the time of the call. Hold.

  At the same time, in this state, the telephone terminal 20A always accepts a call request by the pre-registration 22 to the sending server 14 that has performed the normal call pre-registration process 24 and the call control 28 during the call from the sending server 14 via the mediation server 16. Even if there is a two-way call 29 using a voice protocol in a normal call with another telephone terminal 20B, unless after starting the call control 28 at the time of a call with another sending server, Processing 27 for switching to emergency broadcast stream playback is executed, and a two-way call 26 based on a voice protocol in an emergency call in an emergency is accepted.

  FIG. 2 is a block diagram showing the entire emergency emergency call system when the Internet network 18A is used as a communication network. In FIG. 2, in the Internet network 18A based on the IPv4 or IPv6 method including the private addresses associated with the subordinates, one or more are connected to each device connected with a huge number of unique IP addresses. In the Internet 18A, not only the telephone terminals 20A and 20B but also a great number of telephone terminals 20Z can be connected. Similarly, an intermediary server 16 for intermediating these telephone terminals to a state where communication is possible can be connected from 16A, 16B to a large number of 16Z. In Internet telephone using call control by SIP (Session Initiation Protocol) and voice call by RTP (Real Time Protocol), any specific telephone terminals 20A and 20B are registered in advance in a common mediation server, or mediation servers are It has been widely put into practical use because it is possible to make a call by the RTP codec method determined individually after determining the location of each other by an IP address through an intermediary server.

  The sending server 14 that makes an emergency call to these telephone terminals also implements a similar system, so that a plurality of sending servers 14A and 14B,... It is possible to connect to a large number of Internet networks under independent operation management. However, if the user of the telephone terminal does not accept information from all sending servers, but selects a sending server proactively and accepts only from what it allows, it will be false or malicious. This is not desirable in terms of security management, and information on telephone terminals registered in each intermediary server should be disclosed to the sending server with the intention of the user and not registered in a limited manner. Not preferable.

  In the present invention, a method for maintaining security, which is a problem when an emergency call is made using a telephone that provides such a wide range of communication means, is performed directly from a terminal side to a sending server by a call. Or, it is intended to be carried out efficiently and in a short time indirectly by alternative means, while the emergency contact from the sending server is permitted or intended registered It is possible to receive emergency emergency information consisting of a contact output signal and a voice call only when it is determined whether the IP address of the sending server is used as a source. And

FIG. 3 is a block diagram mainly showing internal configurations of the transmission server and the mediation server. In FIG. 3, the sending server 14 is connected to an external notification device or system such as an external emergency information sending device 12 or an emergency call panel (see Japanese Patent Application No. 2004-232073), or a simple man-machine interface equipped with a monitor screen and a keyboard. The contents of the designated notification are newly stored in the emergency information content storage unit (information content storage unit) 14g or the notification content stored in advance is notified to the emergency information transmission processing unit (information transmission processing unit) 14d. In order to obtain an IP address corresponding to the telephone terminal identifier of the telephone terminal 20A accumulated in the emergency information receiving side terminal identification information storage unit (identification information storage unit) 14c via the activation reception unit 14a, an IP packet is obtained from the call control unit 14b. Queries the mediation server 16 connected to the Internet network 18A via the processing unit 14e. To go. (Alternatively, these processes may be executed and managed as a queue in the activation reception unit and processed one by one, or the execution time may be specified and the execution time may be waited by a timer. .)
In response to the IP address inquiry by the telephone terminal identifier, the intermediary server 16 accepts the telephone terminal identifier by the IP packet processing unit 16c, and corresponds to the telephone terminal identifier previously registered by the telephone terminal 20A by the terminal identification information registration unit 16b. The IP address is acquired from the registered terminal corresponding IP address information database 16 a and returned to the sending server 14. The sending server 14 that has acquired the IP address sends a call request message to the telephone terminal 20A via the Internet 18A, and after the call control is completed via various determination processes in the telephone terminal 20A, Since the control unit 14b notifies the information transmission processing unit 14d of the completion, the information transmission processing unit 14d converts the emergency information notified from the information content storage unit into a voice message by the voice signal modulation unit 14f and converts it into an IP packet processing unit. 14e to the other party's telephone terminal 20A.

  When the information transmission processing unit 14d finishes sending the emergency information, the information transmission processing unit 14d notifies the call control unit 14b of the completion, and the call control unit 14b notifies the external device 12 or the like. The telephone terminal 20A unilaterally receives the emergency information from the transmission server 14 after recognizing and approving the transmission server 14, but the telephone terminal 20A sends the dial tone signal or the like to the transmission server 14 for the contents of the received emergency information. May be reproduced, and bidirectional processing that is accepted by the transmission server 14 may be performed.

  FIG. 4 is a block diagram showing the internal configuration of the telephone terminal device. In FIG. 4, the call request from the sending server 14 is accepted by the IP packet processing unit 20a of the telephone terminal 20 as a plurality of packets constituting the message, but the packet that is sufficient to determine the IP address of the sending server 14 is accepted. At that time, the IP address is notified to the collation unit 20e via the call control unit 20b, and the collation unit 20e recognizes that the notified IP address can be received by the emergency information transmission side identification information storage unit 20d. It is determined whether or not it is accumulated in the.

  If the result of the determination is that they do not match, the acceptance of the call request is abandoned, and if they match, the signal switching processor 20g is notified, and the signal switching processor 20g notifies the contact signal output device 20j to digital Executes output and sends a digital signal to a device built in the terminal or connected to the outside. The digital signal output may be only a switching signal of 1 or 0, or additional communication may be waited for using additional communication means via the Internet to perform more advanced processing.

  Further, the signal switching processing unit 20g confirms whether or not the normal voice processing unit 20c is in operation, and if it is in operation, the signal switching processing unit 20g notifies the outside to execute the process suspension processing or forcibly from the outside. The termination process is executed automatically. Next, the signal switching processing unit 20g notifies the emergency audio processing unit 20f to perform emergency audio processing, and the emergency audio processing unit 20f sends a response message to the transmission server 14 and also uses emergency information. Waiting for the reception of a message, telling the signal switching processing unit 20g that it is in this state, and the signal switching processing unit 20g delivering the emergency information message passed from the emergency voice processing unit 20f to the voice signal demodulation unit 20i To.

  As a result, the emergency information message from the transmission server is transferred from the Internet 18A via the IP packet processing unit 20a to the emergency voice processing unit 20f, and further from the signal switching processing unit 20g to the audio signal demodulating unit 20i such as a speaker. The terminal user is notified by voice. The terminal user may determine the result of the digital output or the information by voice, convert the digital signal from the microphone or dial tone signal device into the digital signal by the voice signal modulation unit 20h, and notify the transmission server 14 in the reverse direction.

  The reception of a series of emergency information messages may be forcibly interrupted by a control from the call control unit 20a using a dial hook or the like during reception, or may be interrupted by receiving an end message from the sending server. If there is processing of the normal voice processing unit 20c, it may be resumed to return to the original normal call state.

  FIG. 5 is a flowchart showing an operation of “normal voice processing → emergency information (digital output and voice information) transmission → return to normal voice processing” in the telephone terminal. In FIG. 5, the following processing is executed.

  In S10, the telephone terminal 20 is registered in the mediation server 16 after activation.

  In S12, the emergency information sending side identification information may be registered directly by reading the dial tone signal from the telephone terminal, or may be registered indirectly from another interface on the Internet. Accumulated in the identification information storage unit 20d. This is registered identification information.

  In S11, after the activation process of S10, a call request is waited for, and a normal call from another telephone terminal or an emergency call from the sending server 16 is waited, but a call request sufficient to determine the IP address of the transmission source After obtaining a packet constituting the message, the IP address is determined and received as identification information.

  In S13, the collation unit 20e determines whether or not the registration identification information stored in the emergency information transmission side identification information storage unit 20d in S12 matches the received identification information. Process as.

  If it is determined in S14 that the two match, it is determined by S13 that the signal switching processing unit 20g converts the signal into a physical electric signal by using a program interface such as a contact signal output device control function. To hand over.

  In S15, the signal switching processing unit 20g interrupts the connection (if a connection exists) between the normal audio processing unit 20c, the audio signal modulation unit 20h, and the audio signal demodulation unit 20i. To the other party, “Communication has been temporarily suspended due to the circumstances of the other party. May be returned.

  In S16, the signal switching processing unit 20g connects the emergency audio processing unit 20f, the audio signal modulation unit 20h, and the audio signal demodulation unit 20i, and waits for ancillary information for the purpose of performing more advanced processing. You may deliver to an output device.

  As will be described later with reference to FIG. 8, the return from the emergency call reception state 36 (see FIG. 8) to the normal call waiting state 32 (see FIG. 8) is a process end message from the sending server 14. It may be recovered by arrival, or may be recovered by forcibly transmitting return information from the call control unit 20b to the collation unit 20e by a specific operation by dial / hook decided in advance.

  FIG. 6 is a sequence diagram showing the “normal call preprocessing” operation in the telephone terminal. In FIG. 6, as will be described later with reference to FIG. 8, the telephone terminal 20 changes from the unactivated state 30 (see FIG. 8) to an activated state by turning on a power switch or the like, and remains in an unregistered state 31 in the mediation server 16. (Refer to FIG. 8) Preferably, however, the registration to the intermediary server is preferably completed automatically, and the telephone can be sent and received.

  The situation will be described with reference to the sequence diagram of FIG. 6. A specific telephone terminal 20A has its own identification information, performs processing 620A to retrieve from the stored location, and IP packet processing unit 20a (see FIG. 4). Through the Internet 18A, the intermediary server 16 is notified of its current IP address, and registration processing 622A that enables transmission and reception is performed. The receiving mediation server 16 executes terminal identification information registration processing 616A. Similarly, the other telephone terminal 20B performs the storage / retrieval processing 620B of the self-identification information, and performs the IP packet processing 622B for registration in the mediation server device.

  Next, processing 624A in which the telephone terminal 20A requests the other telephone terminal 20B to start a call will be described. The telephone terminal 20A hooks up the handset, and the destination telephone terminal input through an interface such as a numeric keypad. With the identification information of 20B, the intermediary server 16 is inquired about the current IP address of the telephone terminal B. The mediation server 16 responds with an IP address as 616B processing. Upon receiving the IP address, the telephone terminal 20A sends a call request message to the telephone 20B, and the telephone terminal 20B performs a ringing sound ringing process 624B and, in some cases, performs an incoming call response 626B, which is used as a message. By replying to the telephone terminal 20A, a call establishment 626A process is performed. The establishment of the above call control may be performed indirectly via a mediation server.

  FIG. 7 is a sequence diagram showing the “normal call to end” operation in the telephone terminal. In FIG. 7, following the operation of FIG. 6 described above, the telephone terminals 20A and 20B during normal communication mutually modulate a voice signal, send it to the other party, and demodulate the signal on the receiving side, so that the operator Convert to audio that can be heard and play. This state is expressed as a modulation process 720A to a demodulation process 720B from the telephone terminals 20A to 20B. Similarly, the reverse is represented by 722B and 722A. When such a series of telephone conversations is terminated, a termination request message is sent from either one to the other party and the conversation is terminated. This state is expressed as a conversation end request process 720A from the telephone terminals 20A to 20B, and the opposite terminal executes the process 724B by receiving it. The reverse is represented by 726B and 726A. The above two processes are terminated by activation of either one.

  FIG. 8 is a state transition diagram of the telephone terminal. In FIG. 8, the state in which the network is not connected after starting from the unstarted state 30 is the mediation server unregistered state 31, and after registration to the mediation server is completed after connecting to the network, the registered incoming call waiting no-call state 32 and Become. If it is not a call request from the IP address of the sending server that registered itself, call control is started for the normal call request and the call preparation process is in progress 33. When a call request is received from another telephone terminal or an unregistered sending server, the call control is terminated and the normal call state 34 is entered. The end of the normal call goes through the reverse state described above and enters the registered incoming call waiting no-call state 32. However, when the terminal itself is disconnected from the network, the intermediate server is not registered via the end processing state 35. 31 or the power supply is cut off, the telephone terminal is not activated, and returns to the state 30.

It is natural that the transmission server that performs emergency emergency broadcasting enters the emergency call state 36 in the registered call waiting no-call state, but in the present invention, the telephone terminal is in the process of preparing for a call 33 that is about to start a normal call. Even in the normal call state 34, the convenience of the user can be improved by giving priority to the emergency emergency call from the transmission server.
When the emergency call request is received during the call preparation process, the state transits to the emergency call state 36 through the state 37 during the cancellation process. In the normal call state 34, the call destination is waited as being on hold processing call, or the normal call is ended as the conversation ends, so that the transition to the emergency call state 36 is made. In addition, when the emergency call is finished, if there is an other party who is put on hold by the emergency call, the normal call state 34 can be returned via the hold process call busy state 38 to release the hold process call. it can. If there is no other party on hold at the time of the emergency call, the process returns to the registered call waiting no-call state 32 and returns to the normal call state 34 assuming that the other party is on hold. If the call has been completed, the process returns to the registered call waiting no-call state 32 through the call preparation process 33.

  FIG. 9 is a sequence diagram showing the operation of “pre-registration / cancellation of emergency information reception”. In FIG. 9, a specific sending server 14A is connected to the Internet network 18A so as to be able to accept a prior registration of emergency information from the telephone terminal 20A, and a registration process 914A is performed in the mediating server 16 so that an IP packet sending process can be performed. The terminal identification information registration process 916A is performed, and the registered information is stored as self identification information 914B.

  On the premise of registration of the sending server described above, the specific telephone terminal 20A registers its identifier information in the sending server 14A with the intention of receiving emergency information, but registration is performed in order to acquire the IP address of the sending server 14A. In the start process 920A, identifier information is sent to the mediation server 16, and after obtaining the IP address obtained by the corresponding IP address search process 916B of the sending server, a call request message is sent to the sending server 14A as a normal call. In the state where the sending server 14A can accept a normal call, if either the registration or cancellation of the terminal is accepted by the voice guidance 914C and the registration process is selected, the intermediary server starts from the sending IP address of the call request message. After the identifier information is taken out and the user is asked for registration confirmation 922A by voice, if the confirmation is completed, a confirmation message is sent to the sending server 14A, and the destination terminal identification information registration processing 914D is performed, and the telephone terminal Also in 20A, the process 924A stored in the emergency information transmission side identification information storage unit 20d (see FIG. 4) is performed.

  Next, the cancellation of the registered telephone terminal will be described. The telephone terminal that wishes to cancel the reception of the emergency information stores the identification information of the transmission server 14A stored in the emergency information transmission side identification information storage unit 20d or recorded by another means in the intermediary server 16 in the same manner as in the registration. When the cancellation confirmation 926A is performed according to the inquiry and the voice guidance 914E, the transmission server 14A performs the notification destination terminal cancellation processing 914F upon receipt of the confirmation message, and the telephone terminal 20A also deletes it from the emergency information transmission side identification information storage unit 20d. Processing 928A is performed.

  The deregistration process of the specific telephone terminal 20A can operate in the same manner in the other telephone terminal 20B, and the transmission server 14A can target the other transmission servers 14B to 14Z. 16 is not limited to a specific mediation server 16A, and other functions having a function of returning an IP address from telephone terminal identification information connected by a server that mediates the mediation server and vice versa. The mediation server 16 may be used.

  FIG. 10 is a sequence diagram showing the operation of “emergency information transmission in terminal state 32”. In FIG. 10, in an emergency, the sending server 14A sends an emergency call request message to the telephone terminal 20A individually or simultaneously in order to make a call request for emergency information to the intermediary server 16. The reception of the emergency call request message is left to the telephone terminal 20A. The registered telephone terminal identification information 1014B that is the reporting partner is transmitted to the intermediary server 16, and as a result, the IP address of the telephone terminal is received and an emergency report request message is transmitted to the telephone terminal 20A via the Internet 18A. When sending emergency information all at once, the emergency information can be read from the destination registration terminal information provided from the intermediary server 16 in order, and the emergency information can be executed according to the above procedure in order. It may be resident as a plurality of program processes for each destination registration terminal and processed simultaneously for a large number of registration terminals by operating simultaneously.

In the telephone terminal 20A that is the recipient of the emergency call request message, as the transmission server identification information storage verification process 40, the IP address of one of the call request sources is the IP registered in advance in the emergency information transmission side storage unit 20d each time. Whether the address is the same as that of the address is sequentially verified by the verification unit 20e, and when there is a match, if there is a normal call, the cancellation process and the hold process 50 are performed. Further, the collation unit 20e performs a process 42 for determining the presence or absence of a preceding emergency call. If there is not, the verification unit 20e returns an emergency call acceptance message 62 to the sending server 14A, and includes a contact point that includes confirmation of the output device opening and normal status return. After the control information delivery process 44 to the signal output device 20j is performed, the normal call suspension shown in FIG. 4 is suspended or terminated, and the reception of the media packet stream as the voice information from the transmission server 14A is waited. (The waiting process when there is a preceding sending server will be described with reference to FIG. 13).
Based on the above, the emergency report request (message activation) from the emergency information transmission server ensures automatic control of devices (lamps, power switches, etc.) built in the terminal or externally connected and the reception status of emergency voice information at the terminal Is done. When the telephone terminal 20A receives the media packet stream from the transmission server 14A, the telephone terminal 20A sequentially performs the audio signal demodulation processing 46, and outputs the audio through a speaker or the like connected to the telephone terminal. During this time, information sent from the telephone terminal 20A may be received and used by waiting for information such as the media packet stream of the dial tone signal and the voice of the user from the telephone terminal 20A on the transmission server 14A side.

  After sending out a series of packet streams, the sending server 14A sends a message so as to return an end request message to the telephone terminal 20A, and finishes receiving the end request by the end completion message received by the end request sending process 48 from the telephone terminal side. The processing 74 may be performed and the processing may be terminated, or the termination request transmission processing 48 may be forcibly executed and terminated by the determination on the telephone terminal 20A side. It is also possible to consider a mechanism that invalidates the forced termination on the terminal side.

  From the reception of the telephone terminal 20A after the above emergency call request message is sent from the sending server 14 to the end request sending 48 and the end request receiving end processing 74 are described later as common processing parts for sending emergency information. Use in.

  In the telephone terminal 20A, after the processing request transmission processing 48 is executed, if there is a holding destination, the processing 52 for confirming and canceling the holding processing of the other party that has been executed in the normal call before receiving the emergency call is canceled. carry out. This state will be described with reference to FIG.

  FIG. 11 is a sequence diagram showing the “emergency information transmission in the terminal state 33” operation. In FIG. 11, the state 33 during call preparation processing of the telephone terminal in the state transition diagram of FIG. 8 is a state between the registered no-waiting call waiting state 32 and the normal call state 34, but in the present invention, Even in this state, it is possible to preferentially transit to the emergency call state 36 through the canceling processing state 37 with respect to the transmission of the emergency call request or the emergency call request message from the transmission server 14A.

  In the state 33 during the call preparation process, the response to the other party's telephone terminal differs depending on whether it is the originating telephone terminal 20A that makes a normal call request or the incoming telephone terminal 20B that receives a normal call request. The timing from when the telephone terminal 20A starts making a call until the incoming telephone terminal 20B establishes a call after answering the incoming call is divided into A and B.

  At timing A, after starting the call control 1122A for inquiring the intermediary server 16 for the terminal identification information of the telephone terminal 20B, the intermediary server 16 searches for the corresponding IP address and returns it to the destination telephone terminal 20B. While the call request message is transmitted and the call is in progress, the telephone terminal 20B is executing the process 1122B for receiving the call request message and generating a ringing tone.

  At timing B, when the incoming telephone terminal 20B executes the incoming call response process 1124B, the ringing of the ringing tone stops and the incoming call response message is sent to the outgoing telephone terminal 20A. The telephone terminal 20A has not completed the acquisition of the incoming call response message, that is, the state 1124A before the call is established.

  The operation in the cancel process for the communication partner performed by the telephone terminal by the arrival of the emergency call request message from the transmission server 14A or the cancel process in progress state 37 in FIG. 8 according to each timing is as follows.

  The telephone terminal 20A on the transmission side at timing A performs a call control process 1126A for canceling the normal call request process interruption in response to the transmission of the emergency call request message from the transmission server 14A.

  The telephone terminal 20B on the receiving side at the timing A performs a call control process 1126B of a busy response during a normal call process for the transmission of the emergency call request message of the transmission server 14A.

  The telephone terminal 20A on the transmission side at timing B performs call control processing 1128A for canceling interruption of normal call processing in response to the transmission of the emergency call request message from the transmission server 14A.
