FIG. 4 is a sequence flow diagram showing the operation of the mobile radio terminal according to the embodiment of the present invention, and the flow of data transmission / reception between the own terminal (mobile phone A) and the counterpart terminal (mobile phone B). It is shown.
In the following description, in order to express the difference between the configuration block of the mobile phone A and the configuration block of the mobile phone B, a suffix a is added after the reference numerals of the configuration blocks of the mobile phone B, and the mobile phone B A suffix “b” is added after the reference numerals of the constituent blocks included in FIG.
Hereinafter, the operation of the mobile radio terminal according to the embodiment of the present invention shown in FIGS. 1 to 3 will be described in detail with reference to the sequence flow of FIG.

First, the user selects the “infrared menu” by operating the operation unit 12a from the mobile menu displayed on the display unit 14a of the mobile phone A, and selects a submenu for starting sharing from the menu. (Step S101).
Receiving this, the control unit 17a randomly selects a photo file or the like in the shared folder 161 stored in a predetermined area of the storage unit 16a, or sets a photo file or the like having a relatively small capacity as a user setting, or Using the automatically selected file as the first authentication data, infrared transmission is performed via the infrared communication unit 18a to the mobile phone B (infrared communication unit 18b) that has been set for infrared reception in advance (step S102).
At this time, the wireless LAN activation request for the mobile phone B is transmitted together with the authentication data, and at the same time, the wireless LAN communication unit 19a is controlled to activate the wireless LAN (step S103).

In step S102, when the control unit 17a selectively transmits the file (first authentication data) in the shared folder 161 stored in the storage unit 16a, the priority listed in (1) to (4) below. According to the order of frequency, the one with the smallest transfer capacity is selected and transmitted by infrared.
A photo file that has already been taken by the imaging unit 15 and registered in the storage unit 16a, and has no transmission history;
A photo file that has already been taken by the imaging unit 15a and registered in the storage unit 16a, and has a transmission history but a relatively small number of transmissions,
A file with no transmission history that is downloaded from the Web (World Wide Web) and registered in the storage unit 16a,
A file having a transmission history that has been downloaded from the Web and registered in the storage unit 16a and has a relatively small number of transmissions.

Also, the mobile phone A (control unit 17a) displays the security level on the display unit 14b of the other party's mobile phone B at the start of sharing depending on which file listed in (1) to (4) above is selected. It shall be.
When only files other than the above (1) to (4) are registered in the storage unit 16a, a display for security alert is displayed on the display unit 14b of the mobile phone B and shared. It is necessary to display a confirmation screen as to whether or not to share the file and confirm whether or not the user intends to share the file.
If no files are registered or only files that cannot be transmitted by infrared, such as files protected by copyright, are registered in the storage unit 16, the fact is displayed on the display unit 14a. To do. Then, the imaging unit 15a is immediately activated to take a photo, and the acquired image is transmitted to the mobile phone B (infrared communication unit 18b) by infrared.

On the other hand, the cellular phone B that has received the wireless LAN activation request including the authentication data by its own infrared communication unit 18b (step S104) stores the authentication data received by the control unit 17b in the storage unit 16b.
The received authentication data is stored in the temporary folder of the storage unit 16b as invisible without allowing the user to recognize the received authentication data (step S105). That is, the authentication data is a file that is not transferred from the IrDA application 171 to a data browsing application (not shown). Or the control part 17b does not notify the address of authentication data to a data browsing application.
Subsequently, the control unit 17b activates the wireless LAN communication unit 19b (step S106), and performs a search for connecting to a portable wireless terminal with the best radio wave state (step S107). If the mobile phone A notifies its own IP address when issuing the wireless LAN activation request, this search is not necessary.

The mobile phone B (control unit 17b) that has finished the terminal search process uses the mobile phone A (wireless LAN communication unit) by the wireless LAN communication unit 19b using the authentication data stored in the temporary storage folder of the storage unit 16b as second authentication data. 19a) performs wireless LAN communication.
Subsequently, the mobile phone A (step S108) that has confirmed the connection uses the control unit 17a to transmit the previously transmitted authentication data (first authentication data) and the received authentication data (second authentication data). Collation is performed (step S109).
Here, when it is recognized that they are the same file, sharing of the “shared folder” is started between the mobile phone A and the mobile phone B, and registered in the shared folder 161 of the storage unit 16a, for example, photo Photo files such as albums are exchanged between the mobile phone A (wireless LAN communication unit 19a) and the mobile phone B (wireless LAN communication unit 19b) by wireless LAN (steps S110 and S111). If it is recognized, the control unit 17a controls the wireless LAN communication unit 19a to disconnect the wireless LAN communication with the mobile phone B (step S112).

When the mobile phone A starts up its own wireless LAN (step S103), the timer built in the control unit 17a is started (step S113), for example, the sharing time of the shared folder 161 is set in advance, such as 5 minutes, By monitoring the time, it is possible to ensure security from others who have the same authentication data.
For example, even if the same authentication data is owned by some method and a connection request is made in a wireless LAN, a timeout is detected (step S114), and even if the same authentication data is used, connection is not performed (step S115). . Conversely, it is possible to respond to reconnection based on the same data until timeout. Once the connection is disconnected, there is no need to set a timeout if the specification is such that the same data is not connected.

  Further, after the sharing of the shared folder 161 is completed (step S116), the mobile phone B (control unit 17b) receives the shared disconnection information from the mobile phone A (control unit 17a) and stores it in the temporary folder of the storage unit 16b. Since the authentication data (file) in the invisible state is deleted, no authentication data remains, so that security can be improved (step S117).

  As described above, according to the portable wireless terminal according to the embodiment of the present invention, since it can communicate only with the other party that is visible, infrared communication with excellent security can be used as a trigger for short-range wireless communication such as a wireless LAN. By starting, data operations such as folder sharing can be easily performed, and a security password or the like is not required, so that the burden on the user is reduced and data sharing and data operations can be easily realized. Further, at this time, further improvement in security can be expected by transmitting authentication data that cannot be known from the user by infrared rays and checking the response to determine whether sharing is possible.

  For users who are not familiar with wireless LAN or Bluetooth (registered trademark), this wireless LAN or Bluetooth (registered trademark) is used to expand infrared communication that has been used for exchanging telephone books. Can be used easily. In this way, user convenience can be improved and file sharing can be realized without requiring special technical skills for the user.
