The display control unit 33, the short-range communication unit 36, and the light emission control unit 38.

  The main control unit 22 is a processing unit that controls the overall operation of the mobile terminal device 1, for example, a CPU (Central Processing Unit). That is, the communication unit 26, the display unit, and the like are executed by appropriate procedures according to the operation of the operation unit 28 and the software stored in the storage unit 24 of the mobile terminal device 1. 32, the operations of the short-range communication unit 36, the light emission control unit 38, and the like are controlled. The main control unit 22 executes processing based on programs (for example, operating system programs, application programs, etc.) stored in the storage unit 24. The storage unit 24 stores software and data used for processing in the main control unit 22. Specifically, as software, software for controlling short-range communication by the short-range communication unit 36, software for controlling operation associated with the specific key 4, software for managing incoming call history, outgoing call history, mail reception history, etc. Is saved. As data, address book data, image data to be displayed on the standby screen, other image data, audio data, and the like are stored.

  The communication unit 26 establishes a radio signal line by a CDMA system or the like with a base station via a channel assigned by the base station, and performs telephone communication and information communication with the base station.

  As described above, the operation unit 28 includes the numeric key 3a, the direction key 3b, the enter key 3c, the function key 3d, and the specific key 4, and when these keys are input by a user operation, A signal corresponding to the operation content is generated. The function key 3d is a key to which an input for starting up various applications such as a mail key, a phone book key, a camera key, a Web key, an end call key (off key), etc. is assigned, and is pressed. Then, the function associated with the key is activated.

  Further, the three specific keys 4 are so-called one-touch keys, and one of the registered users stored in the address book (one registration data and address information) is a specific registered user (pair partner). It is a key that can be associated as When the specific key 4 is pressed, the main control unit 22 can activate a function for making a call to the associated registrant or creating a mail. In the present embodiment, three specific keys 4 are provided, but the number is not particularly limited.

  A signal generated by the operation unit 28 is input to the input data acquisition unit 29 as a user instruction. The input data acquisition unit 29 generates a control signal based on the signal generated from the operation unit 28 and the input setting, and inputs the generated control signal to the main control unit 22. In the present embodiment, a light emission mechanism is arranged on a part of the enter key 3c, the function key 3d, and the specific key 4. The decision key 3c, the function key 3d, and the specific key 4 are formed of a semi-transparent or transparent material, and a light emitting element (LED or the like) is disposed inside.

A video corresponding to the video data supplied via the unit 33 and an image corresponding to the image data are displayed on the display panel.

  The short-range communication unit 36 is a communication unit that communicates with other communication devices using a short-range wireless communication technique. As short-range wireless communication technologies, infrared communication (IrDA (registered trademark), IrMC (registered trademark), IrSimple (registered trademark)), visible light communication, Bluetooth (registered trademark), magnetic field communication (RFID, Radio Frequency Identification) technology can be used. For example, when using the magnetic field communication, the short-range communication unit 36 includes an IC tag that identifies itself and a reading unit that reads an IC tag included in another communication device.

  The light emission control unit 38 controls a part of the light emission state of the operation unit 28. Specifically, the light emission control unit 38 controls the operation of the light emission mechanism arranged corresponding to a part of the determination key 3c, the function key 3d, and / or the specific key 4. Thereby, the light emission control part 38 can make the decision key 3c, the function key 3d, and / or the specific key 4 light-emit, turn off, or blink. In this way, by controlling the lighting state of the key by the light emission control unit 38, the key to be pressed next can be guided. In the present embodiment, the main control unit 22 and the light emission control unit 38 are described separately, but may be integrated. Moreover, although illustration was abbreviate | omitted, the portable terminal device 1 is also provided with the camera.

  Next, the operation of the mobile terminal device 1, specifically, the processing of the near field communication function by the main control unit 22, the communication unit 26, the near field communication unit 36, and the like will be described. Here, FIG.3 and FIG.4 is a flowchart which shows an example of operation | movement of a portable terminal device. 5A and 5B are explanatory diagrams illustrating examples of screens displayed on the display unit of the mobile terminal device. FIG. 3 is a flowchart showing the operation of the mobile terminal device 1 on the side that transmits data by short-range communication, and FIG. 4 shows the operation of the mobile terminal device 1 on the side that receives data by short-range communication. FIG. Moreover, although demonstrated later, the portable terminal devices 1 which perform near field communication of this embodiment fundamentally exchange each other's terminal information and authentication information beforehand. In the following communication, at least two portable terminal devices 1 are used. However, since the configuration of each unit is the same, the reference numerals are the same, and when distinction is necessary, “data transmission side” and “data Both are distinguished as “receiving side”.

  First, the operation of the mobile terminal device 1 on the data transmission side will be described with reference to FIG. The main control unit 22 of the mobile terminal device 1 activates the near field communication unit 36 as step S12 when an activation instruction for the near field communication function is input by a user operation. The start instruction for the near field communication function is, for example, an operation for selecting from the menu screen that the image data is transmitted by the near field communication function when the image data is displayed.

  When the main control unit 22 detects that the specific key 4 is pressed in step S14 with the short-range communication unit 36 activated in step S12, the main control unit 22 is associated with the pressed specific key 4. The registered user is determined as a communication destination for short-range communication.

  When the specific key 4 is pressed in step S14 and the communication destination is specified in step S14, the main control unit 22 transmits mail as step S16. Specifically, the main control unit 22 sends a message including a command for starting the infrared communication function to the other party determined as the communication destination of the short-range communication via the communication line. A message (mail) can be transmitted by an e-mail function or an SMS (Short Message Service) function. Moreover, what is necessary is just to specify the transmission destination of mail based on the correlation with the specific key 4 and a registrant, and the data memorize | stored in the address book. That is, by detecting the e-mail address or the telephone number from the registrant data associated with the specific key 4, the mail transmission destination can be specified. If the telephone number is registered, the SMS is created. If the telephone number is not registered, the e-mail is created.

  When the main control unit 22 transmits the mail in step S16, the main control unit 22 determines in step S18 whether there is a partner for short-range communication. That is, the main control unit 22 determines whether there is a communicable terminal within a range where short-range communication is possible. The main control unit 22 can detect whether there is a communicable terminal by the short-range communication unit 36. In step S18, the main control unit 22 has no partner (No), that is, a terminal capable of communication when no action is received from another terminal to the short-range communication unit 36 even after a predetermined time has elapsed. It is determined that there is not, and the process proceeds to step S18. In this way, the main control unit 22 repeats the process of step S18 a predetermined number of times in order to detect the presence or absence of a communicable terminal. Note that the main control unit 22 may end the process, that is, time out, if a terminal that can communicate after a predetermined number of times is not found.

  When the main control unit 22 receives the communication request in step S18 and determines that there is a partner (Yes), the main control unit 22 returns a response, and in step S20, the authentication is OK based on the data received by the short-range communication. Determine if there is. The main control unit 22 authenticates whether the mobile terminal device detected as the communication partner is the mobile terminal device of the registrant specified in step S14. In addition, the main control unit 22 receives information on the other party's terminal (for example, a telephone number and an email address), information on its own terminal, and authentication information exchanged in advance by the short-range communication unit 36. Authenticate.

  If the main control unit 22 determines in step S20 that the authentication is not OK (No), that is, if the communicable terminal detected in step S18 is not the portable terminal device specified in step S14, the main control unit 22 proceeds to step S18. Thereafter, the main control unit 22 detects other terminals that can communicate, and performs the processes of Step S18 and Step S20.

  If the main control unit 22 determines that the authentication is OK (Yes) in step S20, that is, if it is determined that the communicable terminal detected in step S18 is the portable terminal device specified in step S14, the main control unit 22 determines whether the communication is possible. The start of data transmission / reception after authentication is permitted by distance communication. The main control unit 22 ends the process when the data communication ends.

  In this embodiment, the detection of the activation of the short-range communication unit is detected and then the pressing of the specific key is detected. However, the detection order (the order in which instructions are input by the user) may be reversed. That is, the same processing can be performed when the activation instruction of the short-range communication unit is detected after detecting the pressing of the specific key. For example, the above process can be performed by including activation of the short-range communication unit in a menu (operation) that can be selected after the specific key is pressed. Examples of menus that can be selected after the specific key is pressed include sending to an address associated with the specific key and creating a mail.

  Next, the operation of the mobile terminal device 1 on the data receiving side will be described using FIG. First, the main control unit 22 of the mobile terminal device 1 on the data receiving side receives mail as step S40. That is, the main control unit 22 receives a mail sent from the mobile terminal device 1 on the data transmission side. Specifically, as shown in the screen 52 shown in FIG. 5A, an email including a message requesting to activate the reception function of near field communication (infrared communication in the screen 52) is received. The screen 52 is in a state where the received mail is displayed on the main display 2M.

  When the main control unit 22 receives the mail in step S40, the main control unit 22 analyzes the content, and if it is determined that the mail includes a short-distance communication activation instruction, the main control unit 22 activates the short-range communication unit 36 in step S42. Specifically, the main control unit 22 detects the specific text of the activation request for the near field communication unit 36 included in the mail received in step S40, and automatically activates the near field communication unit 36. In the above embodiment, the short-range communication unit 36 is activated with the reception of mail as a trigger. However, the main control unit 22 activates the short-range communication unit 36 when the display of the mail is completed in step S42. Also good. Further, the main control unit 22 displays a message for selecting whether or not to activate the short-range communication unit on the display unit 32. When the user selects an instruction to activate, the main control unit 22 activates the short-range communication unit. Also good. That is, you may make it start after a user permits. Further, when the short-range communication unit 36 is activated, the main control unit 22 displays the screen 54 shown in FIG. 5-2 on the main display 2M of the display unit 32. Here, the screen 54 displays a message requesting that the communication wave output part of the short-range communication unit 36 be brought close to the communication wave output part of the short-range communication unit 36 of the mobile terminal device 1 on the transmission side. . Note that the screen 54 is a case where infrared communication is used as short-range communication. On the other hand, if the specific text is not included in the mail received in step S40, the main control unit 22 determines that it is normal mail reception and is not required to start near field communication. It does not shift to the processing after S42.

  The main control part 22 will determine whether there exists the other party of near field communication as step S44, if a near field communication part is started by step S42. That is, the main control unit 22 starts sending out a communication request from the short-range communication unit, and determines whether there is a communicable terminal within the range where short-range communication is possible depending on whether or not the response is returned. To do. If the main control unit 22 does not respond within a predetermined time and determines that there is no partner (No) in step S44, the main control unit 22 proceeds to step S44. In this way, the main control unit 22 repeats the process of step S44 a predetermined number of times in order to determine whether there is a communicable terminal. In this case, the main control unit 22 may set a timeout.

  When the main control unit 22 receives the response and determines that there is a partner (Yes) in step S44, the main control unit 22 transmits an authentication code as step S46. That is, the main control unit 22 transmits the authentication code stored in advance in association with the mobile terminal device of the sender of the mail received in step S40 to the transmitting-side mobile terminal device 1 detected as the communication partner. The authentication code is sent by communication by the short-range communication unit. Further, the authentication code may be information set with the mobile terminal device 1 on the transmission side, and as described above, information on the terminal of the other party (for example, telephone number, mail address), or own terminal And authentication information exchanged in advance. Or you may use the information contained in the mail received by step S40.

  After transmitting the authentication code in step S46, the main control unit 22 determines whether data communication is started in step S48. That is, it is determined whether the authentication code is authenticated and data transmission is started from the mobile terminal device 1 on the transmission side. If the main control unit 22 determines in step S48 that data communication is not started (No), the main control unit 22 proceeds to step S44. Thereafter, when the main control unit 22 detects another terminal capable of communication, the main control unit 22 performs the processes of step S46 and step S48.

  If the main control unit 22 determines in step S48 that data communication has started (Yes), the main control unit 22 receives data in step S50. As described above, the mobile terminal device 1 performs correct communication only with the terminal that has truly requested the short-range communication by performing data communication after confirming the authentication with the communication partner and then confirming the authentication. be able to. When reception of data is completed, the main control unit 22 ends the short-range communication unit (stops the function) and ends the process.

  In this way, when the specific key 4 is pressed during short-range communication, the mobile terminal device 1 specifies the registered partner (pair partner) associated with the specific key 4 as the communication destination, and communicates with the communication destination via mail. By starting the near field communication function, it is possible to smoothly perform near field communication.

  Moreover, the other party's portable terminal device 1 to which the mail is transmitted can activate the short-range communication function only by receiving the mail. Accordingly, the function can be activated without inputting an operation for activating the near field communication function from an operation screen such as a menu. As described above, even a user who is unfamiliar with the operation of the mobile terminal device 1 can easily perform near field communication.

  In addition, the mobile terminal device 1 performs authentication before transmitting data, thereby authenticating the partner of the short-range communication, so that when there is a person other than the user authenticated by the user, the mobile terminal device 1 communicates only with the desired partner. Can be established. Thereby, data can be transmitted and received while suppressing leakage of information. Moreover, in the said embodiment, although the portable terminal device 1 of the transmission side performed authentication, you may make it also authenticate the portable terminal device 1 of the receiving side. In addition, since the above effect can be obtained, it is preferable to authenticate the communication destination. However, as described above, the short-distance communication can be easily performed even when short-distance communication is performed without performing authentication. The effect that it is possible can be obtained.

  Also, in the above, although included in the authentication code, it is possible to identify the destination terminal by sending and receiving mails, and perform communication after determining from the terminal information that it is the set partner be able to.

  Moreover, it is preferable that the portable terminal device 1 includes an instruction for starting near field communication in a mail in a sentence that can be understood by a human (language set in the portable terminal), as in the above embodiment. Thus, by including in the mail text, even if the mobile terminal device 1 that has received the mail is the mobile terminal device 1 that does not support the above function, the user can understand the necessary processing. Since the text can be understood by the user in this way, the receiving-side user can also activate the short-range communication unit manually (by user operation) without feeling particular discomfort.

  When the mobile terminal device 1 on the receiving side is a mobile terminal device 1 that does not support the above functions, the user manually activates the short-range communication function and manually inputs an authentication code as necessary. By doing so, it is preferable to set it so that near field communication is possible. Thereby, even when the portable terminal device 1 is not compatible, it is possible to smoothly perform near field communication.

  Further, even when the authentication code is manually input, the mobile terminal device 1 on the transmission side transmits data when the authentication code matches, and does not transmit data when the authentication code does not match. Thus, data can be exchanged safely as described above.

  In addition, when the mobile terminal device 1 on the transmission side is the mobile terminal device 1 that does not support the above function, the mobile terminal device 1 on the transmission side may transmit data without performing authentication. Good. In this case, a message to be selected by the user may be displayed, and it may be determined whether to transmit data based on an instruction input by the user.

  In addition, when the mobile terminal device 1 on the receiving side does not include a predetermined authentication code other than the text of the received mail, or does not include a predetermined command, the mobile terminal device 1 instructs to activate the short-range communication function with text. Even when is displayed, it is preferable not to start the processing shown in FIG. That is, the mobile terminal device 1 on the receiving side performs the processing shown in FIG. 4 when a predetermined authentication code is included in addition to the body of the received mail or when a predetermined command is included. Is preferred.

  Thereby, when the mail of a similar sentence is received, the possibility of starting the short-range communication function by mistake can be suppressed.

  Various methods can be used as a method for including the predetermined command in the mail. For example, you may make it include a command in addition to the mail text. Here, when the command is included in the body of the mail, for example, in the case of the sentence of FIG. 5-1, a half-width space is included between the “phase” and “hand” of the word “partner” or the word “ It is preferable to set as a command a line break or space included in a specific position of a sentence (text), such as including a line break between “start” and “motion” of “startup”. In this way, changing the meaning of a sentence can be suppressed by using spaces and line breaks. Moreover, by including in a peculiar position, for example, in a sentence and in the middle of a line, it is possible to suppress accidental coincidence with a normal mail.

  The mobile terminal device 1 (the main control unit 22) detects a communication partner and performs communication by a normal short-range communication operation when a communication start operation is input without pressing the specific key 4. Just do it. That is, it is preferable to be able to select the activation method of the near field communication function. Thereby, it is possible to perform near field communication with anyone other than the registrant associated with the specific key 4.

  In the above embodiment, the pressing of the specific key 4 is detected after the short-range communication unit 36 is activated. However, the short-range communication unit 36 may be activated after the pressing of the specific key 4 is detected. Good. For example, an instruction to activate a near field communication function may be selected in addition to calling, creating a mail, and displaying detailed information on a menu (selectable function) displayed when the specific key 4 is pressed. In this case, a selection operation of data to be transmitted may be input after an instruction to start the near field communication function is input.

  In addition, when the registered address (pair partner) associated with the specific key 4 does not have an e-mail address (e-mail address) registered, send an e-mail with an SMS service that can send a message by phone number, If only (e-mail address) is registered, the e-mail may be transmitted by e-mail. Moreover, when both are registered, the user may set arbitrarily. Moreover, it is good also as a setting which gives priority and applies one.

  Next, an example of a setting method for performing the above processing will be described with reference to FIGS. 6 and 7 are screen transition diagrams for explaining the operation of the mobile terminal device, respectively. First, as in FIG. 3 described above, a specific key is pressed to start short-range communication (infrared communication in this example). At this time, the communication-destination mobile terminal device 1 is a paired mobile terminal device associated with the specific key. In addition, when the pair partner is not registered in the specific key (not associated), the registration to the pair partner may also be set.

  The mobile terminal device 1 displays a screen 60a shown in FIG. 6 during short-range communication. Thereafter, the mobile terminal device 1 displays the screen 60b when the communication is completed. Here, the screen 60b is a screen for inquiring whether or not to register a communication mode dedicated to the pair partner. In addition, as described above, the communication mode exclusively for the partner of the pair means that a short-distance communication is started after an e-mail including a short-distance communication function activation request is transmitted to the communication destination and authentication is performed with an authentication code. Mode.

  When the mobile terminal device 1 is selected in the state where the screen 60b is displayed, that is, when setting the mode is selected, the mobile terminal device 1 associates the communication mode dedicated to the pair partner with the specific key. That is, when the specific key 4 is pressed, the setting shown in FIG. 3 is performed. Note that, when NO is selected in the state where the screen 60b is displayed, the mobile terminal device 1 is set to not perform the above-described processing of FIG.

  When the setting of the mode is completed, the mobile terminal device 1 displays the screen 60c.

When the authentication code is input and determined in the state where the screen 60d is displayed, the mobile terminal device 1 adds the authentication code information to a part other than the body of the mail requesting the communication mode setting. Thereafter, the mobile terminal device 1 transmits the created mail and ends the process. Note that the mobile terminal device 1 ends the processing as it is when NO, that is, when it is selected not to send an e-mail while the screen 60c is displayed.

  Next, the mobile terminal device 1 that is the communication destination of the mobile terminal device 1 that has performed the process of FIG. 6 receives the mail transmitted from the mobile terminal device 1 that has performed the process of FIG. 6, and opens the received mail. Is input, the screen 62a shown in FIG. 7 is displayed. Here, the received mail is a mail requesting setting of the communication mode, and includes a command requesting activation of processing for performing the corresponding setting. The portable terminal device 1 displays the screen 62b when the mail function end operation is input while the screen 62a is displayed. Here, the screen 62b is a screen for inquiring whether to set the communication mode.

  When the mobile terminal device 1 is displaying YES on the screen 62a, that is, when registration is selected, the mobile terminal device 1 sets the communication mode and, as shown on the screen 62c, the authentication added to the mail. Display code information. Here, the communication mode set by the mobile terminal device 1 as the communication destination is a communication mode in which the short-range communication unit is activated when a mail including a predetermined command is transmitted from the target terminal. Thereby, the portable terminal device 1 can start a short-distance communication part, and can also transmit an authentication code, if the mail of the set conditions is received.

  In the above embodiment, the authentication code is set to an input value arbitrarily input by the user. However, the present invention is not limited to this, and it may be a terminal information or a value set randomly by the apparatus. Further, the authentication code may not be set.

  In addition, if the received email does not contain an authentication code, or if there is no certain command information, the mobile terminal device 1 as the communication destination processes it as a normal received email, It is preferable not to shift to the setting of the communication mode. Thereby, it can suppress performing incorrect registration by false information.

  In the above-described embodiment, the mobile terminal device on the data transmission side transmits a mail (short-distance communication function activation request) that activates short-range communication to the communication destination (the mobile terminal device on the data reception side). However, the mail may be transmitted from the portable terminal device on the data receiving side to the portable terminal device on the data transmitting side.

  Moreover, in the said embodiment, since operation became easier, although demonstrated as a case where short-distance communication was performed with the registration other party (pair other party) matched with the specific key, this invention is not limited to this. For example, the address book may be used to identify the mobile terminal device that is the communication destination (the destination of the mail and the partner of the near field communication). Even in such a case, the mobile terminal device of the communication destination can perform short-range communication only by receiving a mail or simply inputting a simple operation.

  Moreover, in the said embodiment, although both were used as the portable terminal device, this invention is not limited to this, One side is good also as a fixed type terminal device.

  As described above, the mobile terminal device according to the present invention is useful for use in a mobile terminal device having a short-range communication function.
