[Constitution]
FIG. 1 is a diagram showing a configuration of a communication system according to an embodiment of the present invention.
This communication system is composed of a mobile communication terminal 10, normal call terminals 20a, 20b, and 20c, and emergency call terminals 30a, 30b, and 30c, and is a security system for the purpose of security of the user of the mobile communication terminal 10. is there. The mobile communication terminal 10 is a mobile phone terminal here, and is a communication device that performs voice communication and data communication. The mobile communication terminal 10 has a function of performing voice communication and data communication in parallel. The normal call terminals 20a, 20b, and 20c are first terminals that can be voice communication partners with the mobile communication terminal 10, respectively. Here, a telephone having a general configuration that is called by normal use of the mobile communication terminal 10 It is a terminal. The normal call terminals 20a and 20b are, for example, mobile phones possessed by a person such as a family, relative, or friend of the user of the mobile communication terminal 10, and the normal call terminal 20c is, for example, the home of the user of the mobile communication terminal 10 It is a fixed telephone set installed in. Each of the emergency call terminals 30a, 30b, and 30c is a second terminal that can be a communication partner of communication with the mobile communication terminal 10. Here, communication that may be called in an emergency, which is not normal use of the mobile communication terminal 10. It is a terminal. The emergency call terminal 30a is a communication terminal installed in a police station, for example, and the emergency call terminals 30b and 30c are communication terminals installed in a security company with which the user of the mobile communication terminal 10 makes a contract, for example. In the following description, when there is no need to particularly distinguish each of the normal call terminals 20a, 20b, and 20c, they are collectively referred to as “normal call terminals 20”, and the emergency call terminals 30a, 30b, and 30c. When there is no need to distinguish between them, these are collectively referred to as “emergency call terminal 30”. In addition, there are three normal call terminals 20 and three emergency call terminals 30 here, but there may be a larger number or a smaller number.

  The terminals described above are connected to each other via the network NW. The network NW is a communication network including a mobile communication network, a gateway, and the Internet, for example, and functions as a communication path for the mobile communication terminal 10 to perform voice communication and data communication with the normal call terminal 20 and the emergency call terminal 30. . The mobile communication network of the network NW is a mobile communication network based on, for example, IMT-2000 (International Mobile Telecommunications-2000). The mobile communication network of the network NW provides a communication service called a multicall service that can simultaneously provide a voice communication service and a data communication service to a mobile phone. With this multi-call service, the mobile communication terminal 10 uses a plurality of different channels, whereby independent calls are connected, and a communication path established by the connection of the call can be maintained. Thereby, the mobile communication terminal 10 can perform communication (for example, simultaneous call) in parallel with a plurality of terminals.

Next, the configuration of the mobile communication terminal 10 will be described.
FIG. 2 is a front view schematically showing the external appearance of the mobile communication terminal 10, and FIG. 3 is a block diagram showing a hardware configuration of the mobile communication terminal 10.
As shown in FIG. 2, the appearance of the mobile communication terminal 10 is the same as that of a general mobile phone, and each operation key (operator) of the display unit 13 and the operation unit 14 forms the outer shape of the mobile communication terminal 10. The housing 16 is provided. In addition, the mobile communication terminal 10 is provided with a speaker 151 so as to be located near the ear when the user uses the mobile communication terminal 10, and a microphone 152 is provided so as to be located near the mouth at that time. It has been.
The hardware configuration of the mobile communication terminal 10 having the above-described external configuration includes a control unit 11, a wireless communication unit 12, a display unit 13, an operation unit 14, and a voice input / output unit 15.

  The control unit 11 includes a CPU (Central Processing Unit) 11a, a ROM (Read Only Memory) 11b, a RAM (Random Access Memory) 11c, and an EEPROM (Electronically Erasable and Programmable ROM) 11d. The CPU 11a executes a program stored in the ROM 11b or the EEPROM 11d using the RAM 11c as a work area, and controls the operation of each unit of the mobile communication terminal 10. The RAM 11c functions as a memory allocated to the program when the CPU 11a executes the program. The wireless communication unit 12 functions as a communication unit that performs wireless communication with the wireless base station via the antenna 12a and performs voice communication and data communication. The display unit 13 is a display unit that displays an image on a liquid crystal display when the liquid crystal driving circuit performs liquid crystal driving under the control of the control unit 11. The operation unit 14 is an operation means including a plurality of operators such as a so-called numeric keypad, an on-hook key 141, and an off-hook key 142, and three operators such as call buttons 143a, 143b, and 143c. The call buttons 143a, 143b, and 143c are operators that are pressed when designating a communication partner terminal, and play a role equivalent to, for example, an operator that operates a speed dial, a one-touch dial, and a dial transmission restriction function. The call buttons 143a, 143b, and 143c will be described later, but these buttons are collectively referred to as “call buttons 143” when it is not necessary to distinguish these buttons. The operation unit 14 receives a pressing operation of the operator by the user, and outputs operation information corresponding to the operation to the control unit 11. The voice input / output unit 15 is a means for inputting / outputting a voice, and a speaker 151 functioning as a sound emitting means for emitting a transmitted voice, and voice data representing the collected voice by collecting the received voice and collecting the received voice. An output microphone 152 is provided.

  When voice communication is performed in the mobile communication terminal 10, the radio communication unit 12 executes processing such as demodulation when receiving a voice radio signal transmitted from a base station of the mobile communication network by the antenna 12a. The voice input / output unit 15 converts voice data obtained by the processing of the wireless communication unit 12 from a digital format to an analog format and outputs the converted data to the speaker 151 to emit received voice. Further, when the transmitted voice is picked up by the microphone 152 and converted to analog voice data, the voice input / output unit 15 converts the voice into digital format and outputs it to the wireless communication unit 12. The wireless communication unit 12 performs processing such as modulation, and transmits it as an audio wireless signal via the antenna 12a. When data communication such as transmission / reception of electronic mail is performed in the mobile communication terminal 10, when the wireless communication unit 12 receives a data wireless signal transmitted from the base station via the antenna 12 a, the wireless communication circuit 12 demodulates and controls the data wireless signal. The data supplied to the unit 11 and the data supplied from the control unit 11 are modulated and transmitted from the antenna 12a to the base station as a data radio signal.

The EEPROM 11d stores a normal call destination table TB1, an emergency call destination table TB2, and an operation information management table TB3.
FIG. 4 is a diagram illustrating an example of the normal call destination table TB1. The normal call destination table TB1 manages information used when calling the normal call terminal 20.

Are described in association with each other. The callee ID “A1” is assigned to the normal call terminal 20a, the callee ID “A1” is assigned to the normal call terminal 20b, and the callee ID “A3” is assigned to the normal call terminal 20c. In the normal call destination table TB1, the telephone number of each terminal is described in association with each call destination ID.

FIG. 5 is a diagram illustrating an example of the emergency call destination table TB2. The emergency call destination table TB2 manages information used when calling the emergency call terminal 30.
As shown in the figure, also in the emergency call destination table TB2, “call destination ID” which is identification information for identifying the emergency call terminal 30 and “phone number” which is a telephone number assigned to the terminal of the communication partner. Are described in association with each other. The emergency call terminal 30a is assigned a call destination ID “ur1”, the emergency call terminal 30b is assigned a call destination ID “ur2”, and the emergency call terminal 30c is assigned a call destination ID “ur3”. In the emergency call destination table TB2, the telephone number of each terminal is described in association with each call destination ID.

FIG. 6 is a diagram illustrating an example of the operation information management table TB3. The operation information management table TB3 is data defining a correspondence relationship between the call button 143 and a call destination corresponding to the call button.
As shown in FIG. 6, in the operation information management table TB3, various types of information “operator ID”, “operation pattern”, “call destination type”, and “call destination ID” are described in association with each other. ing. In the “operator ID” field, identification information for identifying the call button 143 is described. Here, the operator ID “01” is assigned to the call button 143a, the operator ID “02” is assigned to the call button 143b, and the operator ID “03” is assigned to the call button 143c. In the “operation pattern” field, information representing an operation pattern, which is an operation method performed on the call button 143, is described. “Short-pressing” represents that the continuous pressing time of the call button 143 is a short time, and is assumed to be less than 3 seconds here. “Long press” indicates that the continuous press time of the call button 143 is long, and is predetermined as 3 seconds or more in this case. The operation performed on the call button 143 always corresponds to one of “short time press” and “long time press”. In the “call destination type” field, information indicating the type of the call destination terminal is described. “Normal call destination” indicates that the normal call terminal 20 is a call destination terminal, and “emergency call destination” indicates that the emergency call terminal 30 is a call destination terminal. The operation pattern described in the “operation pattern” in association with the call destination type “emergency call destination” (here, the pressing operation for 3 seconds or more) represents the “abnormal operation pattern”. The operation of the abnormal operation pattern is a predetermined operation method performed on the call button 143 when an abnormality occurs such as when the user is exposed to danger.

  In the “call destination ID” field, the call destinations described in the normal call destination table TB1 and the emergency call destination table TB2 as representing the call destination terminal indicated by the pressing operation performed on the call button 143. ID is described. Also, different call destination IDs are described for “short time press” and “long time press”. As shown in FIG. 6, the call destination ID of one normal call terminal 20 is described in the “call destination ID” field associated with “short press”. On the other hand, in the “call destination ID” field associated with “long press”, the call destination ID described in the “short press” field of the same operator ID and the communication system of this embodiment are displayed. Call destination IDs of all the emergency call terminals 30a, 30b, and 30c that are configured are described. This content is common to each operator ID.

  The call destinations (telephone numbers) described in the normal call destination table TB1 and the emergency call destination table TB2 are entered and registered by the user operating the mobile communication terminal 10, for example. In addition to this, the mobile communication terminal 10 acquires information related to the called terminal from the external storage medium, or acquires by short-range wireless communication such as infrared communication or communication via the communication network NW, The information may be registered in the table, and the configuration for acquiring the information does not matter. Further, instead of the telephone number, information for identifying the communication partner registered in the address book data for realizing the address book function of the mobile communication terminal 10 is described, and the mobile communication terminal 10 May specify the telephone number from the address book data. Further, the operation information management table TB3 may be updated by a user input operation or acquisition of information from the outside.

FIG. 7 is a functional block diagram illustrating functions realized when the control unit 11 calls a terminal that is a communication partner. The control unit 11 executes a program stored in the ROM 11b to realize functions corresponding to the reception unit 111 and the communication control unit 112.
The accepting unit 111 acquires the operation information supplied from the operation unit 14, and accepts the designation of the normal call terminal 20 as a communication partner for voice communication by an operation performed on the call button 143 of the operation unit 14. When the operation for designating the communication partner is accepted by the accepting unit 111, the communication control unit 112 identifies the communication partner according to the operation and calls the normal call terminal 20, and the operation is performed in a predetermined operation pattern. If the call is made, the radio communication unit 12 is controlled to perform communication with the emergency call terminal 30 different from the normal call terminal 20 in parallel with the call or the voice communication.
In this specification, during the period when the call is made, when the control unit 11 instructs the wireless communication unit 12 to call the terminal of the communication partner, the call is started when voice communication with the terminal is started. The period during which voice communication is performed is the period from when voice communication is started until the voice communication is disconnected and ended.

[Operation]
Next, the operation of the mobile communication terminal 10 will be described. Here, the operation of the mobile communication terminal 10 when the call button 143 is pressed to instruct the user to call the communication partner terminal will be described. FIG. 8 is a flowchart showing an operation procedure when the mobile communication terminal 10 calls a terminal to be a communication partner.
First, the control unit 11 determines whether or not the user has pressed down the call button 143 (Step S1). The control unit 11 stands by until a pressing operation of the call button 143 is accepted (step S1; NO). When the pressing operation of the call button 143a is performed here, it is determined as “YES”, and the process of step S2 is performed. move on.

  Next, the control unit 11 determines the type of the called terminal based on the operation pattern of the operation performed on the call button 143 (step S2). Here, the control unit 11 determines the type of the callee that matches the operation pattern of the operation of the call button 143 that has been pressed based on the operation information management table TB3. Here, when a pressing operation for a short time (less than 3 seconds) of the call button 143a is received, the control unit 11 has an operator ID “01” for identifying the call button 143a and an operation pattern “short” in the operation information management table TB3. Reference is made to the “calling destination type” field associated with “time pressing”. As shown in FIG. 6, here, the control unit 11 determines that the call destination is the normal call terminal 20.

  Next, the control unit 11 determines whether or not the call destination determined in step S2 is the normal call terminal 20 (step S3). Here, since the control part 11 determined with it being the normal call terminal 20 by step S2, it determines as "YES" and progresses to the process of step S4.

Then, in response to the operated call button 143, the control unit 11 instructs the communication network NW to call the normal call terminal 20 using the wireless communication unit 12 (step S4). Here, the control unit 11 specifies the callee ID “A1” associated with the operator ID “01” in the operation information management table TB3. Then, the control unit 11 identifies the terminal assigned with the telephone number associated with the callee ID “A1” in the normal callee table TB1 as the communication partner terminal. As shown in FIG. 4, in the normal call destination table TB1, the telephone number “080-1111-aaaa” is described in association with the call destination ID “A1”. Then, when the control unit 11 displays the telephone number on the display unit 13 as an image related to the information related to the normal call terminal 20a, and accepts the pressing operation of the off-hook key 142 by the user, the normal call to which the telephone number is assigned. The wireless communication unit 12 instructs the communication network NW to call the terminal 20a.
When the user of the normal call terminal 20a notices that his / her normal call terminal 20a has an incoming call from the mobile communication terminal 10, the user operates the off-hook key. With this operation as a trigger, the control unit 11 starts voice communication between the mobile communication terminal 10 and the normal call terminal 20a (step S5). Thereafter, the control unit 11 executes various controls related to voice communication.

  On the other hand, when the call button 143a is pressed for a long time (3 seconds or longer), in step S2, the control unit 11 controls the operation ID ID “01” for identifying the call button 143a and the operation in the operation information management table TB3. The “call destination type” field associated with the pattern “long press” is referred to. Then, as illustrated in FIG. 6, the control unit 11 determines that the call destination terminal is the emergency call terminal 30. In this case, since the control unit 11 has accepted the operation of the abnormal operation pattern and is not a call of the normal call terminal 20 (that is, a call of the emergency call terminal 30), it determines “NO” in step S3. The process proceeds to step S6.

  Then, the control unit 11 instructs the communication network NW to call the normal call terminal 20 and the emergency call terminal 30 according to the call button 143 that has received the pressing operation (step S6). Here, the control unit 11 specifies the call destination ID “A1, ur1, ur2, ur3” associated with the operator ID “01” and the call destination type “emergency call destination” in the operation information management table TB3. And the control part 11 identifies the terminal to which the telephone number matched with these call destination ID was allocated as a communication other party terminal in normal call destination table TB1 and emergency call destination table TB2. As shown in FIG. 4, in the normal call destination table TB1, the telephone number “080-1111-aaaa” is described in association with the call destination ID “A1”. As shown in FIG. In the call destination table TB2, the telephone numbers of the terminals serving as communication partners are described in association with the call destination IDs “ur1”, “ur2”, and “ur3”. Therefore, the control unit 11 identifies the emergency call terminals 30a, 30b, and 30c as the communication partner terminals together with the normal call terminal 20a, and calls each terminal. In this way, the control unit 11 performs wireless communication so that calling or voice communication of the normal calling terminal 20a and communication (that is, calling and voice communication) with the emergency call terminal 30 are performed in parallel during the same period. The unit 12 is controlled. The control unit 11 may start calling the emergency call terminal 30 after starting voice communication with the normal call terminal 20a, or may start calling the emergency call terminal 30 first.

  When the users of the normal call terminal 20a and the emergency call terminals 30a, 30b, and 30c notice that there is an incoming call from the mobile communication terminal 10, the user performs an operation for starting voice communication, The control unit 11 starts voice communication with the terminal on which this operation has been performed (step S7). And the control part 11 performs control for performing communication with each terminal used as a communicating party in parallel during the period when the radio | wireless communication part 12 is performing voice communication.

  During the voice communication period, the control unit 11 does not display an image related to information on the emergency call terminal 30 such as a telephone number. The reason why the information about the emergency call terminal 30 is not displayed is that when such a report is made, the user may be exposed to danger by the criminal, and the display content of the display unit 13 is seen by the criminal. This is because there is a fear. That is, in order to prevent the criminal from realizing communication with the emergency call destination, the control unit 11 does not notify information on the emergency call terminal 30. Note that it is also possible for the control unit 11 to display on the display unit 13 only an image relating to the information related to the normal call terminal 20. Since the criminal may force the user to contact the home or the like, in this case, the criminal looks at the display content on the display unit 13 and determines that the normal call terminal 20 is actually being contacted. It is.

  In addition, during the voice communication period, the control unit 11 causes the speaker 151 to emit the received voice from the normal calling terminal 20a without emitting the received voice from the emergency call terminal 30. In other words, the mobile communication terminal 10 exchanges voice with the normal call terminal 20 a, but only sends unilateral transmission voice to the emergency call terminal 30. The reason why the received voice from the emergency call terminal 30 is not emitted is that the criminal may try to talk about the user's family and the received voice may be heard. That is, in order to prevent the criminal from realizing communication with the emergency call destination, the control unit 11 does not emit the incoming voice from the emergency call terminal 30. Note that the control unit 11 may switch whether or not to release the incoming voice from the emergency call terminal 30 according to the operation of the operation unit 14 by the user.

  According to the first embodiment described above, when the mobile communication terminal 10 accepts an operation of the call button 143 for designating a call partner terminal, the communication partner according to the type of the call button 143 operated by the user. Is called and the normal call terminal 20 is called, and when the operation is performed with a predetermined abnormal operation pattern (pressed for a long time in this embodiment), the emergency call terminal 30 is called. . Thereby, the report to the emergency call terminal 30 which requires urgency can be performed rapidly and by simple operation. Further, even after the communication with the emergency call terminal 30 is started, the mobile communication terminal 10 does not continuously display voice communication with the normal call terminal 20 to display information on the emergency call terminal 30, Since the received voice from the terminal 30 is not emitted, communication with the emergency call terminal 30 performed by the mobile communication terminal 10 can be made difficult to be understood by a third party.

[Second Embodiment]
Next, a second embodiment of the present invention will be described.
The second embodiment differs from the first embodiment in that the mobile communication terminal 10 has a configuration in which the emergency call terminal 30 is called during a period in which voice communication with the normal call terminal 20 is performed. The control and the configuration related to the control are the same as in the first embodiment. Accordingly, the same configuration and control as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

[Constitution]
FIG. 9 is a block diagram showing a configuration different from that of the first embodiment among the configurations of the mobile communication terminal 10 of the second embodiment. As shown in the figure, the mobile communication terminal 10 of this embodiment further includes an operation detection unit 17. The operation detection unit 17 is provided, for example, inside the housing 16, and here has a main body of the mobile communication terminal 10, that is, a vibration detection piezoelectric sensor that detects vibration of the housing 16. The vibration detecting piezoelectric sensor is composed of a piezoelectric element or the like, converts mechanical vibration into electric energy, and outputs an electric signal corresponding to the vibration to the control unit 11 as a detection signal. The operation detection unit 17 is an example of a detection unit that detects an operation on the mobile communication terminal 10 that is performed when an external force is applied to the housing 16.

The control unit 11 corresponds to the detection signal acquisition unit 113, the determination unit 114, and the communication control unit 115 shown in the figure when calling the emergency call terminal 30 during the period of voice communication performed with the normal call terminal 20. Realize the function.
The detection signal acquisition unit 113 acquires the detection signal supplied from the operation detection unit 17.
The determination unit 114 determines whether or not an operation of an abnormal operation pattern has been performed on the mobile communication terminal 10 based on the detection signal acquired by the detection signal acquisition unit 113. In this embodiment, the control unit 11 accepts the operation of this abnormal operation pattern as an instruction for calling the emergency call terminal 30. Based on the detection signal, the determination unit 114 is a predetermined condition that means that the external force applied to the housing 16 is large, such as a time when the frequency per unit time is equal to or greater than a threshold value is equal to or greater than a certain time When vibration satisfying the condition is detected by the operation detection unit 17, it is determined that the abnormal operation pattern has been operated. The abnormal operation pattern is not too complicated and is preferably an operation method that is not performed by normal use of the mobile communication terminal 10.
If the determination unit 114 determines that an abnormal operation pattern has been operated during a period during which voice communication with the normal call terminal 20 is performed, the communication control unit 115 communicates with the emergency call terminal 30. The wireless communication unit 12 is controlled to perform communication.

[Operation]
Next, the operation of the mobile communication terminal 10 will be described.
FIG. 10 is a flowchart showing an operation procedure when the mobile communication terminal 10 calls a terminal to be a communication partner. Regarding the operation of this embodiment, the processing steps from step S1 to S7 are the same as those of the first embodiment, and the description thereof is omitted.
The control part 11 performs the process from step S1 to S5 in the same procedure as 1st Embodiment, and starts the voice communication with the normal call terminal 20. FIG. Here, it is assumed that the mobile communication terminal 10 performs voice communication with the normal call terminal 20a.

Next, the control unit 11 determines whether or not to end the voice communication with the normal call terminal 20a (step S8). The termination of the voice communication includes, for example, an operation of pressing the on-hook key 141 of the mobile communication terminal 10, an operation of pressing the on-hook key of the normal calling terminal 20a, or disconnection of communication due to deterioration of radio wave conditions. When the control unit 11 determines to end the voice communication (step S8; YES), the control unit 11 ends the voice communication.
On the other hand, when determining that the voice communication is not terminated (step S8; NO), the control unit 11 continues the voice communication. And the control part 11 determines whether operation of the abnormal operation pattern was received based on the detection signal supplied from the operation detection part 17 (step S9). Here, if the control part 11 determines with not accepting operation of an abnormal operation pattern (step S9; NO), it will return to the process of step S8.

  When the control unit 11 determines that the operation of the abnormal operation pattern has been received (step S9; YES), the emergency call terminal 30 is called wirelessly while continuing voice communication with the normal call terminal 20a with this determination as a trigger. The communication unit 12 instructs the communication network NW (step S10). Here, the control unit 11 refers to the emergency call destination table TB2 and selects all the emergency call terminals 30 (that is, the normal call terminals 20a, 30b, 30c) whose telephone numbers are described in the emergency call destination table TB2. call. When each user of the emergency call terminals 30a, 30b, and 30c operates, for example, an off-hook key for responding to an incoming call from the mobile communication terminal 10, the mobile communication terminal 10 performs voice communication with the terminal that has received this response. Communication is started (step S11). In this way, the control unit 11 controls the wireless communication unit 12 to call the emergency call terminal 30 during voice communication with the normal call terminal 20a. In addition, the operation | movement of the mobile communication terminal 10 after this is the same as 1st Embodiment, The description is abbreviate | omitted.

  According to the second embodiment described above, when the mobile communication terminal 10 determines that an operation of an abnormal operation pattern has been performed by the operation detection unit 17 during a period of voice communication with the normal call terminal 20, an emergency call is made. The terminal 30 is called to perform voice communication. Further, since the mobile communication terminal 10 determines that the vibration of the mobile communication terminal 10 caused by external force applied to the housing 16 is an operation of an abnormal operation pattern, the user of the mobile communication terminal 10 carefully observes the criminal. Even in a situation where the mobile communication terminal 10 is pressed, the mobile communication terminal 10 can make it difficult for a third party to call the emergency call terminal 30 compared to a button press operation or the like. In addition, for example, even when there is an exchange involving a violent action between the user and the criminal, the mobile communication terminal 10 determines that this operation has been accepted by the operation detection unit 17 as an operation of an abnormal operation pattern, and an emergency call is made. The terminal 30 may be called. Thereby, since it is not necessary for the user to consciously perform an operation for reporting to the emergency call terminal 30, a prompt report can be made.

[Modification]
The present invention can be implemented in a form different from the above-described embodiment. The present invention can also be implemented in the following forms, for example. Further, the following modifications may be combined as appropriate.

[Modification 1]
In the first embodiment described above, the operation of the abnormal operation pattern in the mobile communication terminal 10 is an operation of a method of pressing and holding the call button 143 for a predetermined time (for example, 3 seconds) or longer. A pattern may be adopted. For example, the mobile communication terminal 10 may determine that the operation of the abnormal operation pattern has been received when the call button 143 is pressed more than a certain number of times (for example, 3 times in 3 seconds) within a certain period. Alternatively, an operation pattern performed at a predetermined rhythm, such as a Morse code, may be employed. The abnormal operation pattern may be an operation method other than this, and the information is described in the “operation pattern” field of the operation information management table TB3, and the mobile communication terminal 10 operates the abnormal operation pattern according to the information. It may be determined whether it has been performed or an operation pattern that is not an abnormal operation pattern has been operated. Moreover, only the information regarding the abnormal operation pattern may be described in the operation information management table TB3, and an operation pattern other than the abnormal operation pattern may not be defined.

  In the second embodiment described above, the operation of the abnormal operation pattern in the mobile communication terminal 10 is an operation of a method in which the time when the frequency per unit time is equal to or greater than a threshold is equal to or longer than a certain time. Other operation patterns may be adopted. For example, based on a detection signal representing the angle of the mobile communication terminal 10 output by the operation detection unit 17, the operation detection unit 17 has an angle sensor. If it is determined that the change in angle is equal to or greater than the threshold value, it may be determined that an operation of an abnormal operation pattern has been accepted. In addition to this, speed, acceleration, and the like may be adopted. In short, it is determined on the condition that the amount of change in the position or orientation of the mobile communication terminal 10 acting by the external force applied to the housing 16 is equal to or greater than a threshold. Keep it. Then, when the condition is satisfied, the mobile communication terminal 10 assumes that the operation of the abnormal operation pattern has been performed, and performs the above control, thereby making it difficult for a third party to understand the report to the emergency call terminal 30. Can do.

The following may also be used.
In the mobile communication terminal 10, the operation detection unit 17 has a pressure sensor, and this pressure sensor is provided on the side facing the external space of the housing 16. Then, the control unit 11 determines that the pressure applied to the main body of the mobile communication terminal 10 is equal to or greater than the threshold based on the detection signal indicating the pressure applied to the pressure sensor (that is, the casing 16) output from the operation detection unit 17. In this case, it may be determined that the operation of the abnormal operation pattern is accepted. Since a user who has fallen into an emergency may naturally squeeze the main body (housing 16) of the mobile communication terminal 10 as much as possible, the mobile communication terminal 10 is necessary based on a relatively large pressure detected by the pressure sensor. The emergency call terminal 30 can be called at any time. As described above, the fact that the magnitude of the force applied to the housing 16 is equal to or greater than the threshold value may be regarded as an operation of the abnormal operation pattern. That is, in the configuration according to the second embodiment, various dynamic actions that act on the mobile communication terminal 10 by an external force that can be applied to the housing 16, which are not operations performed by the operator, can be employed. In this case, it is preferable that the mobile communication terminal 10 regards the action that occurs when the external force is large as an operation of an abnormal operation pattern. Note that a plurality of actions regarded as operations of the abnormal operation pattern may be combined.
In the second embodiment, the mobile communication terminal 10 operates the abnormal operation pattern described in the first embodiment on the call button 143 and other operators during a voice call with the normal call terminal 20. In response to this, a configuration for calling the emergency call terminal 30 may be adopted.

[Modification 2]
In the first and second embodiments described above, the mobile communication terminal 10 may perform voice communication and data communication as communication with the emergency call terminal 30, or may perform only data communication. Good. This data communication includes, for example, sounding an alarm to notify the emergency call terminal 30 that it is an emergency report or sending an e-mail. Moreover, you may perform the data communication which concerns on the notification of the position where the mobile communication terminal 10 demonstrated below is located.

FIG. 11 is a block diagram showing a configuration different from the first or second embodiment in the configuration of the mobile communication terminal 10 according to this modification. As shown in the figure, the mobile communication terminal 10 of this embodiment further includes a position detection unit 18. The position detector 18 functions as a position detector that detects the location of the mobile communication terminal 10 based on a GPS signal transmitted from, for example, a GPS (Global Positioning System) satellite and outputs detection information representing the detected position. To do. The position detection unit 18 may be configured to detect a position registered in the mobile communication terminal 10 by the user and output detection information representing the position. Further, the control unit 11 realizes functions corresponding to the position acquisition unit 116 and the position output unit 117 shown in FIG. The position acquisition unit 116 acquires the detection information supplied from the position detection unit 18. The position output unit 117 outputs position information indicating the position of the mobile communication terminal 10 to the wireless communication unit 12 based on the detection information acquired by the position acquisition unit 116. This position information represents, for example, longitude and latitude.
When the emergency calling terminal 30 is called or during voice communication with the emergency calling terminal 30, the control unit 11 detects the position by the position detecting unit 18, and the wireless communication unit 12 transmits the position information indicating the position to the emergency calling terminal 30. Send to. The emergency call terminal 30 identifies the position of the mobile communication terminal 10 based on the received position information, and helps the user rescue or the like.

  Further, the control unit 11 may change the emergency call terminal 30 that is a call destination of the voice communication based on the position detected by the position detection unit 18. In this configuration, the location information and the call destination ID of each emergency call terminal 30 are stored in the EEPROM 11d in association with each other. Then, when instructing the emergency call terminal 30 to call, the control unit 11 specifies the call destination ID of the emergency call destination stored in the EEPROM 11d in association with the position information indicating the position detected by the position detection unit 18. Then, a call may be instructed by specifying a telephone number described in the emergency call destination table TB2 in association with the call destination ID. In this way, for example, the mobile communication terminal 10 can select and call the emergency call terminal 30 near the terminal.

[Modification 3]
In the first and second embodiments described above, the control unit 11 of the mobile communication terminal 10 may perform a filtering process for attenuating an audio component corresponding to noise included in audio data output from the microphone 152. .
FIG. 12 is a block diagram showing a configuration different from the first or second embodiment in the configuration of the mobile communication terminal 10 according to this modification. As shown in the figure, the control unit 11 of this embodiment further includes a filter unit 118 that performs the filtering process. The filter unit 118 reduces noise such as ambient sounds and wind noises, that is, sounds other than human voice, from the audio data supplied from the microphone 152, so that the user of the other party's terminal transmits the transmitted voice of the mobile communication terminal 10. Filtering process is performed to make it easier to listen to music. For example, the filter unit 118 includes a microphone dedicated to noise cancellation, and attenuates a voice component corresponding to noise from the voice data of the transmitted voice using dedicated software. In addition, the control unit 11 may perform a process such as detecting a silent state by using a DTX function and not transmitting in the silent state. Note that the filter processing executed by the filter unit 118 may be realized by audio processing by software execution, or may be realized by hardware processing using a band-pass filter or the like, and various known noises. Techniques for removal / reduction can be employed.

  In this modification, the control unit 11 causes the filter unit 118 to perform filtering processing only during a period in which the wireless communication unit does not allow the wireless communication unit 12 to perform voice communication with the emergency call terminal 30, and performs voice communication with the emergency call terminal 30. During the communication period, the filter unit 118 is passed without performing the filtering process. In this way, during the voice communication with the emergency call terminal 30, it becomes easy to hear the voice around the mobile communication terminal 10 on the emergency call terminal 30 side, which is useful for identifying the location of the mobile communication terminal 10 and the surrounding environment. Can be expected. In addition, the mobile communication terminal 10 improves the function of collecting and collecting noise, that is, a voice component corresponding to other than the human voice, during the period during which voice communication with the emergency call terminal 30 is performed. You may perform the process which further raises the sensitivity of the transmission voice of the communication terminal 10. FIG.

[Modification 4]
In the first and second embodiments described above, the control unit 11 of the mobile communication terminal 10 is operated by pressing the on-hook key 141 during a period in which the wireless communication unit 12 performs voice communication with the emergency call terminal 30. Even if an end call operation for disconnecting voice communication such as the above is accepted, the voice communication may be continued without being disconnected. Thereby, even if the criminal forcibly performs the call closing operation on the mobile communication terminal 10, the voice communication is actually continued and the received call is sent to the emergency call terminal 30 so that the criminal is not informed. Can be sent to. In this configuration, the mobile communication terminal 10 actually disconnects the voice communication if, for example, the end-of-call operation is performed a predetermined number of times, for example, the on-hook key 141 is pressed a plurality of times. That's fine.
Further, in this configuration, the configuration of the second modification example is adopted, and the mobile communication terminal 10 may transmit the position information to the emergency call terminal 30 even after the end-of-call operation is performed.

[Modification 5]
In the first and second embodiments described above, the call destination IDs of the normal call terminals 20 are assigned to the call buttons 143 of the mobile communication terminal 10 one by one. An ID may be assigned. In this modification, the case where the mobile communication terminal 10 is provided with only one call button 143 will be described.
FIG. 13 is a diagram showing an example of a call destination table TB4 used in place of the normal call destination table TB1 and the emergency call destination table TB2 in this modification. As shown in the figure, in the call destination table TB4, various types of information such as “operation pattern”, “call destination type”, and “call destination ID” are described in association with each other. Note that the meaning of each information of “operation pattern” and “call destination type” is as described in the first embodiment. In the “call destination ID” field, “A1 → A2 → A3” is described in association with the call destination type “normal call destination”. “A1”, “A2”, and “A3” are identification information for identifying the normal call terminal 20 as in the first embodiment. “→” designates calling in this order. When the call button 143 is pressed for a short time, the control unit 11 specifies that the plurality of normal call terminals 20 are called one by one in accordance with the order of the arrows (that is, relay call is performed). That is, when the control unit 11 accepts the pressing operation of the call button 143, the control unit 11 first instructs the radio communication unit 12 to call the normal call terminal 20a. If there is a response, the control unit 11 starts voice communication with the normal call terminal 20a. On the other hand, if there is no response for a certain period of time, the control unit 11 stops calling the normal calling terminal 20a and instructs the calling of the normal calling terminal 20b. If there is a response from the normal call terminal 20b, the control unit 11 starts voice communication with the normal call terminal 20b. If there is no response for a certain period of time, the control unit 11 stops calling the normal call terminal 20b, and Instruct to call 20c. On the other hand, when the operation with the abnormal operation pattern of the call button 143 is accepted, the control unit 11 calls all the normal call terminals 20 and the emergency call terminals 30 registered in the call destination table TB4. The wireless communication unit 12 is controlled to perform communication in parallel. Thereby, even when there is only one call button 143, the mobile communication terminal 10 assigns a plurality of normal call terminals 20 to the call button 143, and calls or voice communication of the normal call terminal 20 and emergency Communication with the calling terminal 30 can be performed in parallel to promptly report.

Also in this configuration, a plurality of call buttons 143 may be provided. That is, the mobile communication terminal 10 according to the first embodiment and the second embodiment may sequentially call or communicate with a terminal as a communication partner as described above. In this way, even if the mobile communication terminal 10 calls a plurality of terminals in parallel or does not perform voice communication in parallel with the plurality of terminals, the normal call terminal 20 and the emergency call terminal 30 are connected in parallel. And try to communicate.
In addition, the mobile communication terminal 10 is connected to the communication network NW by setting a channel related to voice communication as one channel, not limited to the implementation using the multicall service as described in the first and second embodiments. Simultaneous communication with a plurality of communication partner terminals may be realized by mixing processing on the exchange side. A part of the processing necessary for the mobile communication terminal 10 to call a plurality of communication partner terminals in parallel may be performed in an apparatus other than the mobile communication terminal 10.

[Modification 6]
In the first embodiment described above, the control unit 11 calls the emergency call terminal 30 when the operation pattern accepted by the call button 143 corresponds to the abnormal operation pattern. The emergency call terminal 30 may be called with an operation to be performed.
For example, the mobile communication terminal 10 has an address book function, and this address book function is used to display, for example, a list screen of user names of communication partners for designating the other party's terminal. Then, when the user moves the cursor to the user name desired and performs a pressing operation related to the designation of the other party, the mobile communication terminal 10 determines that the operation does not correspond to the operation of the abnormal operation pattern. If the calling terminal 20 is called and the operation of the abnormal operation pattern is applicable, the emergency calling terminal 30 may be called together with the normal calling terminal 20. Further, when the user directly inputs the telephone number by operating the numeric keypad, for example, if the operation of the off-hook key 142 that is pressed after inputting the telephone number corresponds to the operation of the abnormal operation pattern, the mobile communication terminal 10 The emergency call terminal 30 may be called. As described above, the operation target to be determined whether or not the operation of the abnormal operation pattern is performed is not limited to the above-described ones, and it may be asked whether the operation button is a so-called hard button or a soft button. Absent. In addition, the operator of the mobile communication terminal 10 is not limited to a press operation, and may be a slide switch, for example.

[Modification 7]
In the first and second embodiments described above, the mobile communication terminal 10 may authenticate the user and call the emergency call terminal 30 only when the authentication is successful. Even if the user of the mobile communication terminal 10 does not wish to report to the emergency call terminal 30, an operation corresponding to the abnormal operation pattern is mistakenly performed, or the operation of the abnormal operation pattern is accidentally caused by contact with an object. It is because it is thought that is done.
Therefore, the mobile communication terminal 10 has a sensor for performing fingerprint authentication, vein authentication, and the like, and performs authentication automatically or triggered by operation of a predetermined operator. The mobile communication terminal 10 calls the emergency call terminal 30 only when the operation of the abnormal operation pattern is accepted after the authentication is successful and the user is determined to be a valid user. Note that the type of authentication processing is not particularly limited. However, since the report to the emergency call terminal 30 requires urgency, a complicated operation of the user such as biometrics authentication is involved in order to promptly perform this report. It is preferable to employ an authentication method that is not a thing.

[Modification 8]
In the second embodiment described above, the mobile communication terminal 10 has a configuration for calling the emergency call terminal 30 in accordance with the operation pattern of the call button 143 when voice communication is started. Alternatively, the emergency call terminal 30 may be called only during voice communication. Further, the mobile communication terminal 10 may determine that the operation of the abnormal operation pattern has been accepted, and may terminate the voice communication with the normal call terminal 20 when calling the emergency call terminal 30.
In the first and second embodiments described above, the mobile communication terminal 10 calls the same emergency call terminal 30 regardless of which of the call buttons 143a, 143b, and 143c is operated. It may be different for each. In this configuration, the description of “callee ID” in the operation information management table TB3 may be different for each operator.

[Modification 9]
In the first embodiment described above, the communication system is a crime prevention system for the purpose of crime prevention of the mobile communication terminal 10, but may be applied to a communication system for another purpose. That is, a plurality of call destinations of voice communication are assigned to the operator, and the control unit 11 calls the first terminal if the operation method of the operator does not match a predetermined operation pattern, and the operation method If it agrees with a predetermined operation pattern, the second terminal different from that may be called together with the first terminal. The same applies to the communication system according to the second embodiment, and the control unit 11 is determined in advance to be regarded as an operation of an abnormal operation pattern by the own communication device during the period of performing voice communication with the first terminal. When the operation pattern is operated, the second terminal different from that is instructed while continuing the voice communication with the first terminal. Further, since the mobile communication terminal 10 only needs to select a call destination according to the operation pattern, there is no need to distinguish between the types of terminals of the communication partner.

[Modification 10]
In the first and second embodiments described above, the mobile communication terminal 10 does not display an image related to the information related to the emergency call terminal 30 during voice communication with the emergency call terminal 30 corresponding to the second terminal. However, for example, an image relating to the information may be displayed so that only the user knows that the notification has been successful, and the fact may be notified. Further, the notification mode may be lamp lighting or the like. In addition, the mobile communication terminal 10 did not emit the received voice during voice communication with the emergency call terminal 30, but the sound may be emitted or that the user has performed a predetermined operation. The sound may be emitted as an opportunity.
Since the mobile communication terminal 10 performs communication with the emergency call terminal 30 in parallel with the call of the voice communication with the normal call terminal 20 corresponding to the first terminal or in parallel, only communication with the emergency call terminal 30 is performed. Compared to the case, at least attention to communication with the emergency call terminal 30 is reduced, which contributes to making it difficult for a third party to understand the communication.

In the first and second embodiments described above, the present invention is applied to a mobile phone, but the present invention can also be applied to other electronic devices. The present invention can be applied to various communication devices that perform at least voice communication, such as communication terminal devices such as PDA (Personal Digital Assistance), cameras, portable music players, and portable game machines. In this case, the configuration of display means such as a monitor for displaying various images, sound collection means such as a microphone, operation means including an operator operated by a user, sound emission means such as a speaker, and the like is an external configuration. However, the present invention can be specified. Further, the present invention may be applied not only to a terminal that can perform both voice communication and data communication, but also to an apparatus that can execute only voice communication.
Furthermore, each function which the control part 11 of the mobile communication terminal 10 mentioned above implement | achieves is implement | achieved by the combination of a some program, or may be implement | achieved by cooperation of a some hardware resource.
