Description

  The present invention relates to a data exchange method, a data exchange system, a portable terminal device, and a program, and more particularly to a data exchange method, a data exchange system, a portable terminal device, and a program by communication between portable terminal devices.

  Mobile phones have become widespread, and it is a common practice to exchange telephone directory data such as telephone numbers and email addresses between a plurality of mobile phones. For exchanging the phone book data, near field communication technology such as infrared communication or Bluetooth (registered trademark) is often used.

  When exchanging data in a short-distance communication method such as infrared communication in a portable terminal device such as a cellular phone, data is first transmitted by one portable terminal device and received by the other portable terminal device. It is necessary to complete data transmission / reception in the direction, and then exchange data in the opposite direction to perform data transmission / reception in the reverse direction. Therefore, when attempting to exchange the above phone book data, after performing the data transmission operation to transmit the phone book data, the data reception operation is performed to receive the phone book data (the other is the data after the data reception) Send).

  As described above, when exchanging data such as phonebook data between two mobile terminal devices by a short-range communication method such as infrared communication, it is necessary to transmit and receive data once in each mobile terminal device. It takes time and effort. In particular, in a scene where the telephone directory is exchanged, it can be predicted that data must be mutually exchanged. However, the operation of “reception after transmission” as described above is extremely troublesome for the user.

  Therefore, in the mobile phone having the infrared communication function, the first data transmitted from the other party's mobile phone is received, the second data is transmitted by infrared communication, and the reception of the first data is completed. Accordingly, a mobile phone including a control unit that controls the infrared communication unit so as to transmit the second data has been proposed (see, for example, Patent Document 1). According to the mobile phone described in Patent Document 1, when data reception is completed, the mode is switched to a data transmission mode, and transmission of data selected by the user is started. Therefore, an operation for exchanging data can be simplified.

Further, the data receiving unit 12 and the terminal control unit 21 constitute the first receiving unit 104 in FIG.

  On the other hand, the mobile terminal device B facing the mobile terminal device A has the same configuration as the mobile terminal device A. That is, the mobile terminal device main body 30 of the mobile terminal device B has a data receiving unit 31 such as an infrared communication device for receiving data for mutual exchange and data such as an infrared communication device for transmitting data for mutual exchange. A transmission unit 32, a display unit 33, an input unit 34, and a memory 35 are mounted at least.

  The mobile terminal software 40 causes the computer to function as a terminal control unit 41, a data exchange application 42, and a mutual exchange data storage unit 43. The terminal control unit 41 is central software for controlling the data reception unit 31 and the data transmission unit 32.

In addition, the data receiving unit 31 and the terminal control unit 41 constitute the second receiving unit 204 in FIG. Further, the data transmission unit 32 and the terminal control unit 41 constitute the second transmission unit 203 in FIG.

  In the case of infrared communication, the operation of the data receiving units 12 and 31 is required. However, in the case of data communication using a non-contact type IC card, the receiving device that has received the data transmission automatically receives it. Since the operation is started, there is a case where no operation on the receiving side is necessary.

  Next, the operation of the present embodiment will be described with reference to the flowchart of FIG. In the following description, short-range wireless communication is assumed to be infrared communication. Further, the description will be made assuming that the data to be transmitted / received (exchanged) is telephone book data.

  First, when the mobile terminal device A is activated for the first time after purchase by the user (step S1), an initial setting menu screen for clock setting or the like is displayed on the display unit 13. The user operates the input unit 14 on the basis of the initial setting menu screen to perform predetermined initial settings. At this time, the telephone book data for mutual exchange (such as the telephone number and mail address of the own station) 24a, Image data 24b such as a user's own face photograph is prepared in advance and stored in the interchange data storage unit 23 (step S2).

  Similarly, the portable terminal device B also displays a menu screen for initial setting on the display unit 33 when the power is turned on for the first time after purchase by the user (step S11), and sets the clock by operating the input unit 34 of the user. In addition to the predetermined initial settings, image data 44b such as telephone book data (such as the telephone number and mail address of the local station) 44a and the user's own face is prepared in advance and stored in the exchange data storage unit 43. Store (step S12).

  Assuming that the exchange data is first transmitted from the mobile terminal device A to the mobile terminal device B, the user of the mobile terminal device A on the transmission side operates the input unit 14 to instruct specific data. First, the type of data to be exchanged is selected (step S3). This type of data is, for example, “phone number exchange”, “face photo exchange”, etc., not specific mutual exchange data such as the telephone directory data 24a and image data 24b. This eliminates the need for the user to search for specific mutual exchange data transmitted from the mutual exchange data storage unit 23. Here, it is assumed that the selected type is “telephone number exchange” and the mutual exchange data is telephone book data. By selecting the data type in step S3, the terminal control unit 21 uses the data exchange application 22 to prepare for reading the mutual exchange data corresponding to the selected data type from the mutual exchange data storage unit 23.

  Subsequently, the user of the mobile terminal device A operates the transmission button of the input unit 14 to give a data exchange (transmission) start instruction in which the mobile terminal device B is set to the receiving side (step S4). On the other hand, since the user of the mobile terminal device B that exchanges data with the mobile terminal device A by infrared communication is close to the mobile terminal device A, the user of the mobile terminal device A transmits Can sense operation. Therefore, the user of the mobile terminal device B operates the reception button of the input unit 34 to instruct data exchange (reception) start (step S13).

  Based on the transmission start instruction in step S4, the mobile terminal device A stores data for mutual exchange by the data exchange application 22 based on the type of data (here, “phone number exchange”) selected by the terminal control unit 21 in step S3. The telephone directory data 24a read out from the unit 23 is received as an input and supplied to the data transmission unit 11 to start transmission by infrared communication (step S5). When the portable terminal device A completes the transmission of the phone book data 24a, the terminal control unit 21 detects the completion of transmission and notifies the data exchange application 22 of the start of reception (step S6).

  On the other hand, the mobile terminal device B starts receiving the telephone book data 24a transmitted from the mobile terminal device A by the data receiving unit 31 by infrared communication (step S14). Subsequently, the mobile terminal device B performs processing for saving the phone book data 24a received by the data receiving unit 31 in the memory 35 by the terminal control unit 41 (step S15). The memory 35 is a memory in which data taken by a camera (not shown) of the mobile terminal device B, data downloaded via the Internet, and the like are stored.

  Subsequently, the terminal control unit 41 determines the data format of the received data, and controls the data exchange application 42 to read out the data in the same format as the determined data format from the mutual exchange data storage unit 43 and transmit the data. (Step S16). The above data formats include phone book data (phone number and email address data), still images (face photo data), moving images (moved video data), text data (simple text data such as notes), etc. There is. Here, since the mobile terminal device B receives the phone book data 24a, the terminal control unit 41 determines the phone book data as a data format, and the data exchange application 42 uses the phone book data 44a from the mutual exchange data storage unit 43. Prepare.

  Subsequently, the terminal control unit 41 receives the phone book data 44a from the data exchange application 42 and supplies it to the data transmission unit 32 so as to start transmission (step S17). Thereby, the data transmission part 32 starts transmission to the portable terminal device A of the telephone directory data 44a (step S18).

  On the other hand, following the reception start notification in step S6, the mobile terminal device A starts data reception by the data receiving unit 12 (step S7). Here, when the data receiving unit 12 cannot receive the phone book data 44a from the mobile terminal device B, the mobile terminal device A retries the mobile terminal device B by a known method for the designated number of times. If retry fails, the process ends in error. In this case, only one-way data transmission / reception from the portable terminal device A to the portable terminal device B is completed, and data transmission / reception from the portable terminal device B to the portable terminal device A is not performed.

  When the transmission processing of the phone book data 44a by the mobile terminal device B is completed, all the procedures for data exchange in the mobile terminal device B are completed (step S19). In the mobile terminal device A, when the reception of the phone book data 44a is completed in the data receiving unit 12, the terminal control unit 21 performs processing for saving the phone book data 44a in the memory 15 (step S8). The memory 15 is a memory in which data taken by a camera (not shown) of the mobile terminal device A, data downloaded via the Internet, and the like are stored. After executing the received data saving process in step S8, all procedures for data exchange in the portable terminal device A are completed (step S9).

  The phone book data can be mutually exchanged by the above procedure. Further, in the present embodiment, it is also possible to exchange image data 24b and 44b such as photographs in place of telephone directory data by the same procedure as described above, and to serve as a communication means.

  As described above, in the present embodiment, at the time of data exchange, in the mobile terminal device A on the side of transmitting the exchange data first, the user simply performs the operation of step S3 for selecting the type of the exchange data. Since the mutual exchange data corresponding to the selected type is searched and automatically transmitted, the user of the portable terminal device A does not need to bother searching for the specific mutual exchange data to be exchanged. In addition, since data can be exchanged with only one operation of the mobile terminal device A, operability can be improved.

  Further, in the present embodiment, the mobile terminal device B that receives the first mutual exchange data determines the data format of the received mutual exchange data, and stores the mutual exchange data corresponding to the determined data format. Since it is configured to search from the mutual exchange data storage unit 43 and automatically transmit it, the user of the mobile terminal device B does not need to be aware of the data to be transmitted. The operability can be improved without having to perform the operation.

  Furthermore, in the present embodiment, data exchange of various data formats can be performed by selecting various types (data formats) of interchange data prepared in advance and selecting the data types.

  In the above description of the embodiment, it has been described that the data for mutual exchange is prepared and stored at the time of initial setting. However, the present invention is not limited to this, and the data is not limited to this at the time of initial setting. It is also possible to add and store data for mutual exchange.

  In the above description of the embodiment, data exchange is performed by infrared communication. However, data exchange by communication using a known non-contact type IC card such as FeliCa (registered trademark) is also possible. In this case, if there is data transmission from the transmitting-side mobile terminal device A, the receiving-side mobile terminal device B automatically receives data, and therefore the receiving-side mobile terminal device B does not need to press the receive button. Therefore, step S13 becomes unnecessary.
