  Hereinafter, specific examples of the present invention will be described in detail with reference to examples and drawings. However, the embodiment shown below exemplifies an IP telephone apparatus for embodying the technical idea of the present invention, and is not intended to specify the present invention as this IP telephone apparatus. The present invention is equally applicable to communication devices of other embodiments within the scope of the claims.

  FIG. 1 is a diagram showing a schematic configuration of a telephone system according to an embodiment of the present invention. The telephone system includes an IP (Internet Protocol) telephone device 100, a wired LAN 41, a PSTN (Public Switched Telephone Networks) network 51, a subscriber telephone 52, a SIP (Session Initiation Protocol) server (= call control server) 61, and an IP telephone router 62. , A gateway 63, and an IP telephone network 71.

  The IP telephone device 100 is a communication device capable of voice communication and FAX communication via a telephone network by being connected to a line such as a wired LAN 41. The IP telephone device 100 also has a function of receiving an emergency earthquake bulletin distributed by the Japan Meteorological Agency via the IP communication network 71 or the like. Details of the internal structure of IP telephone apparatus 100 will be described later.

  The wired LAN 41 is a local network in which the IP telephone device 100, the SIP server 61, the IP telephone router 62, the gateway 63, and the like are connected by wire. Each of the above-described devices can communicate with each other by being connected to the wired LAN 41. Examples of physical means constituting the wired LAN 41 include 10BASE-T (standardized as IEEE802.3i) and 100BASE-TX (standardized as IEEE802.3u) using a twisted pair cable.

  The PSTN network 51 is a general subscriber telephone line network. The PSTN network 51 is used for making a voice call by connecting a subscriber telephone 52 to a terminal and connecting to a communication partner by a circuit switching method. The subscriber telephone device 52 is a telephone device that allows a telephone subscriber to make a voice call with another subscriber telephone device or the IP telephone device 100 using the PSTN network 51.

  The SIP server 61 is a communication control device that uses SIP to control communication with the IP telephone device 100 connected to the wired LAN 41. SIP is a kind of call control protocol having a transfer function, a caller ID notification function, and the like, and has a feature that it takes less time to connect than a protocol of the same system.

  The SIP server 61 has functions such as a register server in which an SIP client such as the IP telephone apparatus 100 registers an address, a proxy server that searches for an address on behalf of the client, and a redirect server that transfers a connection request received from the client to another address. It has.

  The IP telephone router 62 is a network relay device for interconnecting a plurality of IP networks. Specifically, a part of the protocol of the network layer (third layer) and the transport layer (fourth layer) in the OSI (Open Systems Interconnection) reference model is analyzed and transferred. In the present embodiment, the IP telephone router 62 has a role of connecting two IP networks of the wired LAN 41 and the IP telephone network 71 to each other.

  The gateway 63 is a protocol converter for interconnecting networks having different protocol systems. The gateway 63 of the present embodiment connects the wired LAN 41 and the PSTN network 51 and performs signal conversion using a signaling protocol such as SIP, thereby enabling communication between both networks.

  The IP telephone network 71 is a communication network using VoIP (Voice over Internet Protocol) technology for part or all of the telephone network. A so-called broadband line such as FTTH (Fiber To The Home) or ADSL (Asymmetric Digital Subscriber Line) is used as a communication line to be used.

  Note that VoIP is a technique in which voice is compressed by various encoding methods, converted into packets, and transmitted in real time over an IP network. As a result, the IP telephone network 71 can provide a videophone service for transmitting and receiving images in addition to a voice call service.

  Next, the configuration of the IP telephone apparatus according to the embodiment of the present invention will be described.

  FIG. 2 is a block diagram showing the main configuration of the IP telephone apparatus 100 according to the embodiment of the present invention. IP telephone apparatus 100 is configured to include a main body 10 and a receiver 20. The main body 10 includes at least a control unit 11 (= control unit), a memory 12 (= storage unit), a display unit 13, an operation unit 14, a communication control unit 15 (= communication unit), a clock circuit 16 (= time measuring unit), And a signal processing unit 17. The receiver 20 includes a speaker 21 and a microphone 22.

  The main unit 10 and the receiver 20 may be connected using a wired cable (not shown) or connected to each other using wireless communication by providing a wireless unit (not shown). But you can.

  The control unit 11 is a central processing unit for performing overall control of communication control processing (transmission / reception of voice data, execution of outgoing calls, detection of incoming calls, etc.) by controlling each part of the IP telephone device 100. The control unit 11 includes a disaster information reception unit 11a (= reception unit), a registration unit 11b, and a counter unit 11c as functional units realized by executing a predetermined program on the arithmetic processing device included in the control unit 11. I have.

  The disaster information receiving unit 11 a receives disaster information such as an earthquake early warning from the IP telephone network 71 using the communication control unit 15. For earthquake early warnings, earthquake detection time, earthquake identification number, epicenter name code, epicenter latitude / longitude, epicenter depth, magnitude, maximum predicted seismic intensity, data accuracy (system and processing method used for measurement, etc.) Etc. are included. However, the predicted seismic intensity included in the earthquake early warning and the predicted time to reach the main motion are rough, and it is necessary to calculate the detailed predicted seismic intensity for each region on the receiver side.

  There are two types of calculation processing: single observation point processing and multiple observation point processing. The single observation point process is a local one-point measurement process based on the assumption that an earthquake has occurred near the observation point, such as P-wave detection and level method. The multi-observation point process is for calculating the predicted seismic intensity and the main motion arrival time of a specific place using the results of the plurality of single measurement point processes. Typical processing methods include a territory method and a grid search method.

  The disaster information receiving unit 11 a performs multiple observation point processing based on the single observation point processing result included in the earthquake early warning and the latitude / longitude information recorded in the memory 12. Specifically, for example, first, the three elements of the earthquake (the epicenter: X, Y, the time: T, the magnitude: M) are obtained from the processing results of a plurality of single observation points. Further, the sensitive radius R is obtained from the epicenter distance (distance from the epicenter X, Y to the specific location X0, Y0) D and the magnitude M of the earthquake. Here, the specific location means the latitude / longitude where the IP telephone device 100 exists.

  The disaster information receiving unit 11a obtains the standard strength Sr at a specific location from the epicenter distance D, the magnitude M of the earthquake, and the depth H of the epicenter. Then, the amplification factor A at a specific location according to the geological condition is obtained, and the predicted intensity, maximum speed, maximum acceleration, maximum displacement, and predicted arrival time of the main motion (S wave) are obtained using the standard intensity Sr and the amplification coefficient A. Ask. Note that the calculation method used by the disaster information receiving unit 11a is not limited to the above-described content, and can be appropriately changed according to the operation mode and the data content included in the earthquake early warning.

  The registration unit 11b is connected to the subscriber telephone 52 of the partner to be preferentially connected, which is identification information for identifying a specific partner to be preferentially connected that is input from the operation unit 14 to the memory 12. Registration processing of the assigned telephone number and the IP address assigned to the destination IP telephone apparatus 100 to be preferentially connected is performed.

  The counter unit 11c counts the elapsed time after the notification is completed by the clock circuit 16 when the display unit 12 performs notification processing on the disaster information received by the disaster information reception unit 11a. When the count time (= measurement time) exceeds a predetermined time, for example, 30 minutes, the control unit 11 communicates with the SIP server 61 connected to the network, as will be described later. When an incoming call is received, the communication control unit 15 is instructed to perform a normal incoming call response process for incoming calls from all destinations.

  Further, when the count time does not exceed the predetermined time, the control unit 11 receives an incoming call by the communication control unit 15 communicating with the SIP server 61 connected to the network, as will be described later. The communication control unit 15 is instructed to perform normal incoming call response processing for incoming calls from the other party to be preferentially connected, and busy response processing for incoming calls from other than the other party to be preferentially connected is performed. Direct the implementation.

  It is assumed that the length of the predetermined time is recorded in advance in the program executed by the memory 12 or the control unit 11 and set in advance at the time of factory shipment. Alternatively, a predetermined length of time desired by the user may be set from the operation unit 14 and recorded in the memory 12. When the display unit 12 notifies the user of new disaster information received by the disaster information receiving unit 11a, the counter unit 11c initializes the count time and then starts counting again. .

  The memory 12 is a medium for temporarily recording various data held by the IP telephone device 100. The memory 12 temporarily stores processing data when various communication control processes are performed by the control unit 11, an instruction command received from the user by the operation unit 14, a telephone number for identifying a partner to be preferentially connected, and the like. It serves as a buffer memory for recording.

  The display unit 13 displays various types of information held by the IP telephone device 100, for example, a caller telephone number at the time of incoming call to the user. The display unit 13 uses, for example, a small display device that consumes less power, such as a liquid crystal panel.

  The operation unit 14 is for the user to operate the IP telephone apparatus 100 using the main body unit 10. The operation unit 14 accepts various operations for performing communication, for example, input of a telephone number of a partner with whom a call is made. The operation unit 14 is usually configured to include a plurality of operation keys such as numeric keys and redial keys.

  The communication control unit 15 is a communication interface for connecting the IP telephone apparatus 100 to a telephone line. The communication control unit 15 can perform incoming processing or outgoing processing of a voice call by communicating with the SIP server 61 connected to the network.

  The clock circuit 16 is a circuit for measuring the current time, and for example, uses a crystal resonator that performs oscillation output at a predetermined frequency. The clock circuit 16 can manage not only time information but also calendar information related to the calendar such as the current month and day.

  The signal processing unit 17 performs a decoding process on the audio data input by the communication control unit 15. The audio signal obtained by decoding is given to the speaker 21. In addition, the signal processing unit 17 performs a predetermined encoding process on the audio signal input from the microphone 22 to generate audio data, and supplies the audio data to the communication control unit 15. As a result, the audio data is transmitted to other communication devices connected via the PSTN network 51.

  The speaker 21 included in the receiver 20 is a voice output device that outputs a call voice. The microphone 22 is a voice input device for inputting call voice.

  Next, the incoming call response process using the IP telephone apparatus 100 configured as described above will be described with reference to the flowchart of FIG.

  First, the control unit 11 determines whether or not an incoming INVITE message has been received from the SIP server 61 by the communication control unit 15 while waiting for reception of an incoming signal (step S11). When it is determined that the communication control unit 15 has received the INVITE message (YES in step S11), the control unit 11 receives disaster information and completes the notification based on the measurement time counted by the clock circuit 16 by the counter unit 11c. It is determined whether or not the elapsed time is within a predetermined time (step S12).

  If the elapsed time is within the predetermined time (YES in step S12), the incoming destination telephone number and the family or emergency registered in the memory 12 based on the INVITE message received by the communication control unit 15 By comparing with the telephone number of the contact, it is determined whether or not the received incoming call is an incoming call from other than a specific destination to be preferentially connected (step S13). If it is from other than a specific destination (that is, it is determined that the destination is a low-priority destination that does not need to be preferentially connected) (YES in step S13), a busy response process is automatically performed ( Step S14) and the process is terminated.

  Here, FIG. 4 is a sequence diagram showing an example of the busy response process. The example of FIG. 4 shows a busy response sequence by SIP, which is a typical call control protocol of the IP telephone system. Normally, a SIP server exists between the IP telephone apparatus and the destination telephone, but the description is omitted here for the sake of simplicity.

  When a call origination operation is performed from destination subscriber telephone 52 to IP telephone apparatus 100, an INVITE message is transmitted (phase F41). Receiving this, the IP telephone device 100 does not accept the incoming call based on the transmission source telephone number, IP address, etc. included in the INVITE message and performs a busy response process, and a 486 Busy Here message is sent to the destination subscriber telephone 52. It is transmitted (phase F42).

  Then, ACK indicating that the 486 Busy Here message has been received is returned to IP telephone apparatus 100 at partner subscriber telephone 52 (phase F43). As a result, a busy tone is emitted from the destination subscriber telephone 52.

  On the other hand, when the elapsed time after completion of the disaster information notification is not within the predetermined time in Step S12 (NO in Step S12), the control unit 11 or the incoming call received in Step S13 is not from a specific partner ( That is, if it is determined that the destination is a high-priority partner that needs to be preferentially connected (NO in step S13), normal incoming call response processing is performed (step S15), and the processing is terminated.

  Here, FIG. 5 is a sequence diagram showing an example of an incoming call response process. In the example of FIG. 5, an incoming call response sequence by SIP which is a typical call control protocol of the IP telephone system is shown. Note that the description of the SIP server is omitted here in order to simplify the description as in FIG.

  When a call origination operation is performed from destination subscriber telephone 52 to IP telephone apparatus 100, an INVITE message is transmitted (phase F51). Receiving this, the IP telephone device 100 receives the incoming call based on the transmission source telephone number, IP address, etc. included in the INVITE message and enters the incoming state, and a 180 Ringing message is transmitted to the destination subscriber telephone 52. (Phase F52). In response to this, the destination subscriber telephone 52 enters a calling state.

  Next, when a response operation such as raising the handset 20 is performed in the IP telephone apparatus 100, a 200 OK message is transmitted to the destination subscriber telephone 52 (phase F53).

  Then, ACK indicating that the 200 OK message has been received is returned to IP telephone apparatus 100 at partner subscriber telephone 52 (phase F54). Thereby, a two-way voice call is established between the IP telephone apparatus 100 and the destination subscriber telephone 52.

  According to the present embodiment described above, immediately after receiving disaster information such as an earthquake early warning, the communication apparatus automatically handles a low-priority partner that does not need to be preferentially connected regardless of the user operation. To respond busy. For this reason, safety confirmation immediately after the occurrence of a disaster such as an earthquake can be performed smoothly.

  In the above embodiment, in order to identify a specific destination to be preferentially connected, the telephone number of the destination to be preferentially connected is stored in the memory 12 by the registration unit 11b. The telephone number of the other party that does not need to be connected may be stored in the memory 12.

  In the above embodiment, the wired LAN 41 and the IP telephone network 71 are used as communication lines for the IP telephone apparatus 100 to receive the earthquake early warning, but other communication networks such as a dedicated line or the Internet are used. The form which receives emergency earthquake early warning from may be sufficient. Moreover, the form which acquires an earthquake early warning from a broadcast wave like terrestrial digital broadcasting and BS digital broadcasting may be sufficient.

  In the above embodiment, the IP telephone apparatus 100 is described as an example of the communication apparatus. However, the present invention is not limited to this, and the present invention can be applied to other communication apparatuses as long as the IP telephone apparatus can be connected to a wide area communication network. May be implemented. For example, the embodiment may be implemented in a FAX apparatus, a mobile phone, an Internet phone, a parent / child phone, or the like.
