JP5413273B2 - COMMUNICATION DEVICE, COMMUNICATION METHOD, AND COMMUNICATION PROGRAM - Google Patents

Description

  The present invention relates to a communication device, a communication method, and a communication program.

  Conventionally, a voice communication terminal such as a portable terminal is used for emergency calls (eg, 110) to emergency contacts such as the police, which is a special line that can be accepted even if the caller unilaterally hangs up. Unless the line is disconnected at the receiving stand on the side, the line on the network is forcibly continued. The reception desk, which is an emergency contact, can also call back the caller and perform reverse detection.

  For example, when the 110th report was made, the police who received the report at the 110th reception desk could not judge whether the report itself was an incident unless they were able to converse with the reporter. Can not do it. However, in a case where there is a risk that a criminal is nearby, even if the 110th call can be made, it is not possible to make a call. In this case, even if the police receives an emergency call at the 100th reception desk, the police cannot talk to the caller and cannot recognize the incident. Therefore, the initial action is not performed, the case resolution is delayed, and the damage is expanded.

  And the portable terminal etc. which prevent the 3rd party, such as a criminal, noticing that the 110th report was made in the case of such a 110th report are disclosed. For example, by starting a special purpose application such as an emergency call program, the mobile terminal starts sending emergency information such as 110. Then, the mobile terminal displays the standby screen or controls not to display the screen, and hides from the third party that the 110th call destination police is in communication. In addition, the mobile terminal does not end the disconnection with the 110th report destination police unless it accepts an emergency call end queue operation known only by the owner of the mobile terminal. By using such a portable terminal, the whistleblower can talk to the police without the third party noticing that the 110th call has been made.

JP-A-2005-341302

  However, in the conventional technology, there is a high risk that the terminal that made the emergency call is broken by a third party, and communication with the emergency contact is cut off, so that emergency information cannot be provided.

  Specifically, it is assumed that the third party has made a call by taking the portable terminal on which the special purpose application is activated. In this case, the display of the mobile terminal is in a state where the standby screen is displayed or nothing is displayed. Therefore, the third party makes a call by a normal operation such as dial number input. However, since the mobile terminal is in a state where communication is connected to the 110th receiving stand, for example, it does not accept outgoing calls from third parties.

  As a result, the third party is distrusted or notices that he / she has been contacted 110, and is likely to destroy the mobile terminal. And if a portable terminal is destroyed, communication with the 110th receiving stand will be cut | disconnected and emergency information cannot be provided to the police.

  The disclosed technology has been made in view of the above, and is capable of providing emergency information to an emergency contact while concealing that an emergency call has been made from a third party, and a communication method And to provide a communication program.

  In one aspect, a communication apparatus, a communication method, and a communication program disclosed in the present application include a first communication establishment unit that establishes communication with an emergency contact by calling an emergency contact, and an emergency is performed by the first communication establishment unit. In a state where communication with a contact is established, a reception unit that accepts a call operation to another contact, and a call that is already established when a call operation to another contact is accepted by the reception unit While maintaining communication with the emergency contact, the channel used for communication with the emergency contact is switched to another channel or other channel other than the used channel is used to A second communication establishment unit that establishes communication with the contact.

  According to one aspect of the communication device, the communication method, and the communication program disclosed in the present application, it is possible to provide emergency information to an emergency contact while concealing that an emergency call has been made from a third party. There is an effect.

  Hereinafter, embodiments of a communication device, a communication method, and a communication program disclosed in the present application will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

  FIG. 1 is a diagram illustrating the mobile terminal according to the first embodiment. Here, a mobile terminal will be described as an example, but the present application is not limited to this, and an information processing apparatus capable of voice communication such as a PHS (Personal Handy-phone System) terminal, a mobile communication terminal, or a PDA. Any terminal can be applied.

[Configuration of mobile terminal]
The mobile terminal 1 according to the first embodiment includes a voice communication function by telephone, a web communication function such as Internet history, a mail transmission / reception function for transmitting / receiving e-mail and SMS (Short Message Service), and an image to be captured and processed. It has a processing function. That is, the mobile terminal 1 has the same function as a general mobile terminal. Furthermore, the portable terminal 1 has the 1st communication establishment part 1a, the reception part 1b, and the 2nd communication establishment part 1c, as shown in FIG.

  The first communication establishment unit 1a establishes communication with the emergency contact by calling the emergency contact. For example, when the first communication establishment unit 1a receives an input of the 110th dial signal from the user, the first communication establishment unit 1a transmits the call to the 110th number and receives a response from the police 110th reception table. When the first communication establishment unit 1a receives a response from the police station 110, the first communication establishment unit 1a uses the CS dedicated channel used for normal telephone calls and the like in the circuit switching (CS) circuit, Establish communication with the 110th receiving stand.

  More specifically, when the first communication establishment unit 1a receives an input of the 110th dial signal by an operation from the owner of the mobile terminal 1 that has witnessed the crime, the first communication establishment unit 1a transmits the 110th number and sends the 110th number of the police. Accept a response from the reception desk. And the 1st communication establishment part 1a will establish communication with the police 110th receiving stand using a CS separate channel, if a response is received from the 110th receiving stand of the police.

  The receiving unit 1b receives a call operation to another contact in a state where communication with the emergency contact is established by the first communication establishing unit 1a. For example, the accepting unit 1b accepts an input of a dial signal of 03-xxx-xxxx in a state where communication with the 110th receiving stand is established by the first communication establishing unit 1a, and receives the accepted dial signal as the second It outputs to the communication establishment part 1c.

  More specifically, the reception unit 1b is configured such that the mobile terminal 1 is deprived by a criminal while the communication with the 110th reception table is established by the first communication establishment unit 1a. The input of a dial signal of -xxx-xxxx is accepted. Then, the reception unit 1b outputs the received dial signal to the second communication establishment unit 1c.

  The second communication establishment unit 1c communicates with other contacts while maintaining communication with the already established emergency contact when the receiving unit 1b receives a call operation to another contact. Establish. Specifically, the second communication establishment unit 1c switches the channel used for communication with the emergency contact to another channel or uses another channel other than the channel used for other communication. Establish communication with the destination.

  For example, when communication is established with the 110th receiving platform using the CS dedicated channel, the second communication establishing unit 1c is normally used for transmission / reception of control signals other than calls in a circuit switched network. Establish communication with other contacts using the control channel. More specifically, when communication is established with the 110th reception stand using the CS dedicated channel, the second communication establishing unit 1c uses the CS control channel to newly receive 03-xxx. -Send to xxx. And if the 2nd communication establishment part 1c receives a response from 03-xxx-xxx, it establishes communication between 03-xxx-xxx using a CS control channel, maintaining communication of CS separate channel .

  In addition, the first communication establishment unit 1a may perform transmission to No. 110 using the CS control channel. In this case, the second communication establishment unit 1c uses the CS dedicated channel and uses 03-xxx. -Send to xxxx. The first communication establishment unit 1a and the second communication establishment unit 1c can establish communication using a packet switched (PS) network in addition to the circuit switched network. The second communication establishment unit 1c can use a channel other than the channel established by the first communication establishment unit 1a, and the channel established by the first communication establishment unit 1a can be used as another channel. To establish communication. That is, the combination of the channel established by the first communication establishment unit 1a and the channel established by the second communication establishment unit 1c can be arbitrarily selected.

  Therefore, a combination of a channel established by the first communication establishment unit 1a and a channel established by the second communication establishment unit 1c will be described with reference to FIG. FIG. 2 is a diagram for explaining channel combinations to be established.

  The “emergency call” illustrated in FIG. 2 is, for example, the above-described 110, and indicates communication with the emergency contact address transmitted by the first communication establishment unit 1a. The “criminal call (new call)” is, for example, the above-described 03-xxx-xxx, and indicates communication transmitted by the second communication establishment unit 1c in a state where communication with the emergency contact is established. . “Switching destination” indicates which channel is used when a criminal call is made in a state where an emergency call is connected.

  Also, “CS individual” shown in FIG. 2 is a call channel used for a normal call or the like in a circuit switched network, and “CS control” is a transmission / reception of a control signal other than a call normally in the circuit switched network. The control channel used for is shown. Further, “PS individual” shown in FIG. 2 is a communication channel used for normal packet communication or the like in the packet switching network, and “PS control” is a control signal other than normal communication in the packet switching network. Indicates a control channel used for transmission and reception.

  For example, it is assumed that the second communication establishment unit 1c transmits a “criminal call” using a channel of the CS network in a state where the “emergency call” is established through the “CS dedicated channel”. In this case, the second communication establishment unit 1c can transmit the “criminal call” using the “CS control channel” while maintaining the “CS dedicated channel” of the “emergency call”. In addition, the second communication establishment unit 1c switches the “emergency call” channel from the “CS dedicated channel” to the “CS control channel” to maintain communication, and uses the “CS dedicated channel” to perform “criminal call”. Can be sent. In addition, the second communication establishment unit 1c switches the “emergency call” channel from the “CS individual channel” to the “PS individual channel” to maintain communication, and uses the “CS individual channel” to perform the “criminal call”. Can be sent. Further, the second communication establishment unit 1c switches the channel of the “emergency call” from the “CS dedicated channel” to the “PS control channel” to maintain the communication, and uses the “CS dedicated channel” to perform the “criminal call”. Can be sent.

  For example, it is assumed that the second communication establishment unit 1c transmits a “criminal call” using a channel of the PS network in a state where the “emergency call” is established through the “CS dedicated channel”. Note that the transmission using the channel of the PS network is, for example, a case where transmission is performed using VoIP (Voice over Internet Protocol) using SIP (Session Initiation Protocol) or the like. Establishing a connection by Web communication such as the Internet also corresponds to sending using a PS network channel. In this case, the second communication establishment unit 1c can transmit the “criminal call” using the “PS dedicated channel” while maintaining the “CS dedicated channel” of the “emergency call”.

  For example, it is assumed that the second communication establishment unit 1c transmits the “criminal call” using the channel of the CS network in a state where the “emergency call” is established through the “PS dedicated channel”. In this case, the second communication establishment unit 1c can transmit the “criminal call” using the “CS individual channel” while maintaining the “PS individual channel” of the “emergency call”.

  For example, it is assumed that the second communication establishment unit 1c transmits a “criminal call” using a channel of the PS network in a state where the “emergency call” is established through the “PS dedicated channel”. In this case, the second communication establishment unit 1c can transmit the “criminal call” using the “PS control channel” while maintaining the “PS dedicated channel” of the “emergency call”. Further, the second communication establishment unit 1c can transmit the “criminal call” using the “PS dedicated channel” of another connection while maintaining the “PS dedicated channel” as the “emergency call” channel. At this time, the second communication establishment unit 1c hides the “PS dedicated channel” of the “emergency call” so that it is not displayed on the display or the like. Further, the second communication establishment unit 1c switches the “emergency call” channel from the “PS dedicated channel” to the “PS control channel” and maintains the communication, and uses the “PS dedicated channel” to perform the “criminal call”. Can be sent.

  Next, control for switching the dedicated channel to the control channel will be described with reference to FIG. As shown in FIG. 3, a physical channel (DPDCH: Dedicated Physical Data Channel) used for communication has a dedicated channel (DTCH: Dedicated Traffic Channel) and a control channel (DCCH: Dedicated Control Channel). Then, the first communication establishing unit 1a normally divides the data obtained by adding the CRC (Cyclic Redundancy Check) code to the user data to be communicated and turbo-decoding into a plurality of physical channels by an interleaving technique, and as a packet Send.

  On the other hand, the control channel has a data area for storing a header and user data, and a padding area for adjusting the length of the packet. Normally, control signals and the like are stored in the data area of the control channel, but in the present application, channel switching is performed by storing and transmitting data exchanged in the individual channel in this data area. Specifically, the second communication establishment unit 1c adds a CRC code to data having a data area storing user data, a header, and padding. Subsequently, the second communication establishment unit 1c divides the data decoded by the Viterbi decoder into a plurality of physical channels by an interleaving method, and transmits it as a packet. FIG. 3 is a diagram illustrating control for switching the dedicated channel to the control channel.

  As described above, the mobile terminal 1 performs channel switching by performing control so that communication is performed using either the dedicated channel or the control channel of the physical channel.

[Process flow]
Next, the flow of processing by the mobile terminal 1 described above will be described with reference to FIG. FIG. 4 is a flowchart illustrating a process flow in the mobile terminal according to the first embodiment.

  As shown in FIG. 4, when the first communication establishment unit 1a accepts a call operation to the emergency contact (Yes in Step S101), the first communication establishment unit 1a makes a call to the emergency contact (Step S102). Thereafter, the first communication establishment unit 1a accepts a response from the emergency contact and establishes voice communication with the emergency contact using an arbitrary channel (step S103).

  In this state, the second communication establishment unit 1c determines whether or not the own device is in the emergency mode state when the receiving unit 1b receives a call operation to another contact (Yes in step S104). (Step S105). For example, the second communication establishing unit 1c determines whether or not the own device is in a call with the emergency contact at the time when the receiving unit 1b receives a call operation to another contact.

And the 2nd communication establishment part 1c implements channel control, maintaining the communication of an emergency contact address, when an own apparatus is an emergency mode state (step S105 affirmation) (step S106). Subsequently, the second communication establishment unit 1c uses the channel selected by the channel control,
While maintaining the communication of the emergency contact, a call is established to another device to establish voice communication (step S107).

  On the other hand, when the own apparatus is not in the emergency mode state (No at Step S105), the second communication establishment unit 1c releases a channel used for communication with the emergency contact (Step S108). Subsequently, the second communication establishment unit 1c transmits to another device (step S109), receives a response from the other device, and establishes voice communication with the other device using an arbitrary channel (step S110). ).

[Effects of Example 1]
As described above, according to the first embodiment, even when a call is received to another device during a call with an emergency contact number such as 110, the communication with the emergency contact is maintained and the other device is maintained. You can make a call. For example, even if a person who witnessed a criminal took 110th on a mobile terminal, even if the mobile terminal was taken away by a criminal, the criminal can make a call operation. They do not notice that they have been contacted and are less likely to destroy their mobile devices. Therefore, it is possible to provide emergency information to the emergency contact address while concealing that the emergency call has been made from a third party.

[Mobile terminal state transition]
Next, state transition of the mobile terminal according to the second embodiment will be described with reference to FIGS. FIG. 6 is a diagram showing the relationship of state transition between the normal state and the emergency mode state, FIG. 7 is a diagram showing state transition from the standby state of the emergency mode state to the out-of-service state, and FIG. It is a figure which shows the state transition from the standby state of an emergency mode state to a battery exhaustion state.

(Relationship between normal state and emergency mode state)
As shown in FIG. 6, the mobile terminal 10 normally transitions between four states. Specifically, when the power button is pressed in the power OFF state, the mobile terminal 10 changes the state to the standby state. Then, when an off-hook or dial signal is received by the key operation unit 14 in the standby state, the mobile terminal 10 changes the state to the outgoing call state, and then receives the response signal and changes the state to the communication state. In addition, when the on-hook is received by the key operation unit 14 in the communication state, the mobile terminal 10 changes the state to the standby state. In addition, when the power button is pressed in the standby state, the mobile terminal 10 changes the state to the power OFF state.

  When the dial number of the emergency contact number such as 110 is accepted by the key operation unit 14 in the standby state, the mobile terminal 10 changes the state to the emergency mode calling state and then receives the response signal. The state is changed to the mode standby state. The mobile terminal 10 in the emergency mode standby state is in a call state with the 110th receiving stand that is an emergency contact. Further, even when an arbitrary button operation is accepted by the key operation unit 14 in the emergency mode transmission state, the mobile terminal 10 maintains the emergency mode transmission state and outputs a normal standby screen to the display unit 16. .

  When the power button is pressed in the emergency mode standby state, the mobile terminal 10 changes the state to the emergency mode power OFF state. At this time, the mobile terminal 10 is in a call state with the 110th reception desk, which is an emergency contact, but turns off the screen display. Further, the mobile terminal 10 maintains the emergency mode power OFF state even when an arbitrary button operation is accepted by the key operation unit 14 in the emergency mode power OFF state. Further, the mobile terminal 10 maintains the emergency mode standby state even when an arbitrary button operation is received by the key operation unit 14 in the emergency mode standby state.

  Then, when the off-hook or new dial signal is received by the key operation unit 14 in the emergency mode standby state, the mobile terminal 10 changes the state to the emergency mode second calling state. At this time, the portable terminal 10 performs control such as channel switching while maintaining a call state with the 110th reception desk that is an emergency contact, and assigns a channel to a new dial signal and transmits it. Thereafter, when receiving the response signal, the mobile terminal 10 changes the state from the emergency mode second outgoing call state to the emergency mode second outgoing communication state. At this time, the mobile terminal 10 establishes a call with the second call destination using the newly assigned channel while maintaining a call state with the 110th reception desk, which is an emergency contact.

  And if the on-hook is received by the key operation part 14 in the emergency mode 2nd transmission state, the portable terminal 10 will change a state to an emergency mode standby state. At this time, the mobile terminal 10 disconnects the call with the second call destination while maintaining the call state with the 110th reception desk, which is an emergency contact. Further, the mobile terminal 10 executes the state transition of FIG. 7 when it is out of service area in the emergency mode standby state, and executes the state transition of FIG. 8 when the battery runs out in the emergency mode standby state. To do.

(State transition from standby mode in emergency mode to out-of-service state)
As illustrated in FIG. 7, when the mobile terminal 10 goes out of service in the emergency mode standby state, the mobile terminal 10 changes the state from the emergency mode standby state to the emergency mode out of service state. At this time, the mobile terminal 10 is disconnected from the 110th reception stand as an emergency contact, but the recording control unit 25 starts voice recording and the like. Moreover, the portable terminal 10 receives the information of the 110th receiving stand connected using mail methods, such as SMS, and provides the information of an own apparatus to the 110th receiving stand.

  Thereafter, when the mobile terminal 10 is in a range, the mobile terminal 10 changes the state from the emergency mode out-of-service state to the emergency mode reconnection state. At this time, the portable terminal 10 reconnects to the 110th reception table that was in a call state before out of service using the 110th reception table information received by SMS or the like.

  And the portable terminal 10 will change a state to the emergency mode reconnection call state, if a response is received from the 110th reception stand. At this time, the mobile terminal 10 is in a call state with the 110th receiving stand that was in a call state before out of service, and ends the voice recording. The mobile terminal 10 that has finished the voice recording transitions the state from the emergency mode reconnection call state to the emergency mode information transmission state. At this time, the mobile terminal 10 transmits the audio signal recorded when out of service area to the 110th receiving table. In addition, the portable terminal 10 displays an out-of-service display or the like on the display unit 16 while transmitting the recorded audio signal. And the portable terminal 10 will change a state to emergency mode standby state, if transmission of the recorded audio | voice signal is completed.

(State transition from standby mode in emergency mode to dead battery state)
As illustrated in FIG. 8, when the battery runs out in the emergency mode standby state, the mobile terminal 10 changes the state from the emergency mode standby state to the emergency mode mobile search state. At this time, the mobile terminal 10 searches for mobile terminals that exist in the vicinity using the device search unit 28 while maintaining a call state with the 110th receiving stand.

  Subsequently, when the mobile terminal 10 detects a mobile terminal existing in the vicinity, the mobile terminal 10 changes the state to the emergency mode search mobile activation state. At this time, the mobile terminal 10 starts communication with the mobile terminal searched by the device search unit 28 while maintaining a call state with the 110th receiving stand.

Send it with an email. The destination information includes, for example, an IP address and a URL (Uniform Resource Locator). Accordingly, the mail control unit 23 of the mobile terminal 10 displays “request to mobile terminal = standby screen display, additional information = transmission destination information such as recording data and recording data” in the received mail. Processes such as 15 are executed.

  In addition, when the emergency contact address transmits information about the device itself to the mobile terminal 10 by e-mail, the control information “request to the mobile terminal = information notification, additional information = e-mail destination information” is added to the e-mail. To do. The mail transmission destination information includes, for example, a mail address. This information is used, for example, when the emergency contact address transmits information about the device itself to the mobile terminal 10 in FIGS.

(Example of signal to be added to e-mail: E-mail from mobile terminal to emergency contact)
Further, when the battery dead alarm is transmitted to the emergency contact in FIG. 17 or the like, the mobile terminal 10 sends an email including “notification = battery alarm notification, additional information = IP address or phone number of the mobile terminal” to the emergency contact. Send to. In addition, when a proxy connection notification is transmitted to the emergency contact in FIG. 15 or the like, the search phone urgently sends an email including “notification = proxy connection notification, additional information = IP address or telephone number of requesting mobile terminal”. Send to contacts.

(Control combination)
Further, the mobile terminal need not execute all the various processes described in the second embodiment, and can execute an arbitrarily selected process. Also, a plurality of processes can be arbitrarily selected. In the embodiment, the 110th reception table is described as an example of the emergency contact, but the present invention is not limited to this, and can be applied to various emergency contacts such as 119.

(Switch back)
For example, assume that the second outgoing communication is established using the channel used for the emergency call after switching the emergency call channel to a different channel. Thereafter, when the second call is disconnected, the emergency call may be controlled to return to the original channel. In this way, the channel that was originally used can be used. Therefore, even if the emergency call is inconvenient on the channel switched by the second transmission, the original channel can be used, so that information loss can be minimized.

(system)
In addition, among the processes described in the present embodiment, all or a part of the processes described as being automatically performed can be manually performed. Alternatively, all or part of the processing described as being performed manually can be automatically performed by a known method. In addition, the processing procedures, control procedures, and specific names shown in the above-mentioned documents and drawings, for example, information including various data and parameters shown in FIG. 2 and the like are arbitrarily changed unless otherwise specified. be able to.

  Further, each component of each illustrated apparatus is functionally conceptual, and does not necessarily need to be physically configured as illustrated. That is, the specific form of distribution / integration of each device is not limited to that shown in the figure. For example, all or a part thereof can be configured to be functionally or physically distributed / integrated in arbitrary units according to various loads or usage conditions. Furthermore, each processing function performed by each device can be realized by a CPU and a program that is analyzed and executed by the CPU.

(program)
The optical switch control method described in this embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program can be distributed via a network such as the Internet. The program can also be executed by being recorded on a computer-readable recording medium such as a hard disk, a flexible disk (FD), a CD-ROM, an MO, and a DVD and being read from the recording medium by the computer.
