The mobile phone 10 to which the present invention is applied is used for establishing communication. Is transmitted to the personal computer 50, which is a peripheral device, and communication with the personal computer 50 by Bluetooth can be established. In this case, the password is
It serves as a password for Bluetooth link authentication.

The mobile phone 10 is configured as described above. The present invention provides a telephone number search function (phonebook search function).
Is used to search for a password used for object exchange or the like. For example, the mobile phone 10 has a general function as described below as a telephone directory search function. An example of a telephone number search and telephone call (calling) function performed by using a general mobile phone telephone directory search function will be described with reference to FIG.

As shown in FIG. 3, in step S1, in response to an operation of a predetermined key (search start key) of the operation unit 18 performed by the user, in step S2, the mobile phone stores the shortened memory (telephone number). After searching, in step S3, the shortened memory (telephone number) is displayed on the display unit 17.
To be displayed.

That is, for example, when a predetermined key (for example, a search start key) of the operation unit 18 is pressed, the portable telephone 10 activates a telephone directory search function, and
Display part 1 displays the telephone number (part of the telephone directory) registered in 6.
7 is displayed. Then, the mobile phone 10 displays, for example, a scroll display of the list of the telephone directory on the display unit 17 in response to a key operation or the like performed as an operation in the telephone directory search function.

The user determines whether or not the shortened memory displayed on the display unit 17 is the desired shortened memory (step S4). If the shortened memory is not the desired shortened memory, the user proceeds to step S1 to make a telephone call from the user. A number search operation (for example, search by scroll display) is performed again.

On the other hand, if the desired memory is the desired shortened memory, the call button is pressed by the user in step S5, and in step S6, the portable telephone calls the designated telephone number. Thereby, step S
At 7, the calling number is sent from the mobile phone RF unit 12 to the base station, and the base station's corresponding telephone is called.

As described above, the telephone directory search function has a function that allows a user to search for a desired telephone number and make a call. The mobile phone 10 thus makes it possible to search for a password by using the telephone directory search function normally used when making a call.

Although the telephone directory search function of the mobile phone 10 to which the present invention is applied has been described with reference to FIG. 3, the present invention is not limited to the operation of the telephone directory search function of the mobile phone 10 only as described above. Needless to say.
That is, the purpose of the present invention is to search for a password using a general telephone directory search function that is constructed as an information search function for a telephone number (phone directory) as a search target.

In the present invention, it is assumed that a password is registered in a telephone directory. For example, a password is registered in a telephone directory by using a function of registering a telephone number in the telephone directory. Shall be performed. Hereinafter, the password registered in the telephone directory is referred to as a registered password.

Next, an outline of communication performed between the mobile phone 10 and the personal computer 50 which is an external device will be described first. As a specific example, a case where business card information (object) is exchanged between the mobile phone 10 and the personal computer 50 will be described with reference to FIG.

It is assumed that the mobile phone 10 and the personal computer 50 are already in a communication connection state in which normal data can be transmitted and received. That is, the processing in the mobile phone 10 and the personal computer 50 described below is processing under a communication state in which normal data including a password and the like can be transmitted and received.

First, the user selects a business card exchange mode in the mobile phone 10 (step S11), and selects a connection destination, that is, a peripheral device to be exchanged with business card information for data communication. On the other hand, the user sets the business card exchange mode also for the personal computer 50 (step S12). And the personal computer 50
It is known from the selection information (selection request) of the peripheral device transmitted from the mobile phone 10 that the user has been selected as the connection target. In response, the personal computer 50 requests the mobile phone 10 to input a password (step S13).

The mobile phone 10 inputs a password in response to the password input request of the personal computer 50 (step S14). At this time, in the case of a conventional mobile phone, the user inputs a password. However, in the case of the mobile phone 10 to which the present invention has been applied, a search for a registered password is performed using a telephone directory search function.

The mobile phone 10 sets the password selected and read by the user using the telephone directory search function (step S14), and transmits the password to the personal computer 50 (step S15). The personal computer 50 checks the sent password (step S16). That is, the personal computer 50 checks with a password whether or not the mobile phone is a mobile phone for which transmission and reception of special data is permitted.

When the personal computer 50 confirms that the mobile phone is permitted to exchange business card information by a password, the personal computer 50 returns the fact to the mobile phone 10. Thereby, the mobile phone 10 recognizes that it has entered the business card exchange mode with the personal computer 50, that is, that the business card data can be exchanged. For example, the mobile phone 10 notifies the user of the fact that the user has entered the business card exchange mode by outputting a voice from the speaker 21 or displaying it on the display unit 17 (step S17). Thereafter, business card data is exchanged between the mobile phone 10 and the personal computer 50 (step S18).

As described above, the password is authenticated between the mobile phone 10 and the personal computer 50 using the password, and the transmission and reception (exchange) of the object such as the business card data becomes possible. In the above example, transmission / reception (exchange) of information is enabled by authentication of a password. However, communication can be established by authentication of a password.
Is described as an example.

Next, the processing in the mobile phone 10 and the personal computer (peripheral device) 50 will be specifically described with reference to the flowcharts shown in FIGS.

FIG. 5 is a flowchart showing a processing procedure which has been made possible by using a conventional portable telephone. FIG. 6 is a flowchart compared with FIG.
4 shows a processing procedure enabled by using the mobile phone 10 to which the present invention is applied. In this example, the mobile phone 10
And the personal computer 50 has communication means 30, 51
This is an example of a case where communication means according to Bluetooth is provided. First, a processing procedure enabled by a conventional mobile phone will be described with reference to FIG.

First, steps S21 and S22
In, the user, the mobile phone and peripheral devices Bluetoot
Turn h on. Thereby, in step S23, the mobile phone searches for radio waves of connectable Bluetooth peripheral devices (outer peripheral devices, external devices). In step S24, the mobile phone displays the outer peripheral devices connectable to the display unit (screen). Is displayed. As described above, Bluetooth enables communication between a plurality of devices. Therefore, a plurality of peripheral devices that can be connected to the mobile phone by Bluetooth are displayed on the display unit of the mobile phone.

Then, in step S25, the user sees such a display on the display unit and presses a key (by operating the operation unit) to select a peripheral device (for example, a personal computer) to be connected. Then, in step S26, the mobile phone transmits a connection request command from the Bluetooth RF unit. Then, the peripheral device receives a connection request command via the Bluetooth RF unit.

In step S27, the peripheral device transmits (inputs) a password for authenticating the other party.
(Hereinafter, referred to as a password input request command) to the mobile phone via Bluetooth. In step S28, the mobile phone receives the password input request command and displays on the display unit a message prompting the user to input the password.

At step S29, the user who sees the display prompting for the input of the password presses a key to input a password number (numerical number), and then presses a key for confirming the password at step S30. In a conventional mobile phone, the password is thus input by being directly input by the user.

In response to such a user operation,
In step S31, the mobile phone sends a password command to the peripheral device via the Bluetooth RF unit. In the peripheral device, steps S32 and S33
Verify whether the transmitted password is correct.

If the password is correct, the peripheral device proceeds to step S34 and indicates that the mobile phone has been authenticated (authentication O).
K) command (hereinafter, referred to as an authentication completion command).
To the mobile phone via the RF section of Bluetooth.
In step S35, upon receiving the authentication completion command, the mobile phone confirms that the communication path with the peripheral device has been secured, and displays on the display unit that the authentication has been performed (authentication OK). . Then, thereafter, in step S36, the communication of the data such as the business card data described above (the above-described predetermined communication state) is started between the mobile phone and the peripheral device.

On the other hand, if it is determined that the password is not correct as a result of the password verification in step S33, a process of securing a communication path is performed in step S37. For example, in the case of a mobile phone, a message indicating that securing of a communication path has failed is displayed on a display unit. Note that, in step S33, the processing of the communication path securing failure is described as an example, but generally, the transition to the predetermined communication state fails, and therefore, transmission and reception of predetermined data (objects and the like) is performed. This may be the case when it becomes impossible to do so. The same applies hereinafter. As described above, the communication with the peripheral device has been performed by the conventional mobile phone.

As described above, in the conventional mobile phone, since the user directly inputs the password, the user is required to memorize the password consisting of a series of symbols.
The burden on the user was heavy. Further, even if the user remembers the wrong password input, the above-mentioned transition to the predetermined communication state may fail. The mobile phone to which the present invention is applied solves such a problem. A processing procedure enabled by the mobile phone 10 to which the present invention is applied will be described with reference to FIG.

The mobile phone 10 to which the present invention is applied is characterized in that a password is searched for by a telephone directory search function, and therefore, a part of the case where the mobile phone to which the present invention is applied is used. Is substantially the same as the processing performed when a conventional mobile phone is used. Specifically, steps S41 to S48 shown in FIG.
Mobile phone 10 to which the present invention is applied from peripheral devices
The processing up to the password input request made for the mobile phone is the same as the processing up to the password input request made from the peripheral device to the mobile phone in steps S21 to S28 when the conventional mobile phone shown in FIG. The same applies to steps S52 to S52 shown in FIG.
The process from the process of transmitting the selected password to the peripheral device, which is performed in step S58, to the process of establishing communication is as follows:
This is the same as the process from the process of transmitting the selected password to the peripheral device in steps S31 to S37 when the conventional mobile phone shown in FIG. 5 is used to the start of predetermined data communication. I have.
In the following description, a mobile phone 10 to which the present invention is applied
The same processing as that performed when a conventional mobile phone is used is omitted when processing is performed. The processing realized by applying the present invention is the processing of steps S49 to S51, and the processing of this part will be described below.

In step S48 (step S28), the user who sees the display prompting the user to input the password on the display unit 17 of the mobile phone 10 determines in step S49 a certain key (for example, a key for starting the telephone directory search mode). (Search start key, etc.) to switch to the telephone directory search mode. Then, in step S50, the user searches for a corresponding registered password registered in the telephone directory. The registration password is a password registered in the telephone directory in advance, and since the retrieval of the registration password is enabled by the telephone directory search mode,
The user can search for the corresponding registered password by performing a button operation similar to the operation in the telephone directory search mode. That is, the telephone number can be easily found in the same manner as when the telephone number is found. And
If the user finds the desired registration password in step S51, the user determines the registration password as the contents of the telephone directory.

[0056] the mobile phone 10 sends selected as described above (confirmed) has been registered password, in step S52 (step S31), the peripheral device via the RF unit 31 ₂ of the Bluetooth. Thereafter, as in the case of using the conventional mobile phone, processing for password authentication, predetermined data communication, and the like are performed.

As described above, the peripheral device (personal computer 50) is operated by the portable telephone 10 to which the present invention is applied.
The communication with is performed.

Although the above description of the password search in steps S49 to S51 has been made by way of example of a manual operation by the user, the search for the registered password can be automated to some extent.

For example, as shown in FIG.
8 (step S28), the mobile phone 10 receiving the password input request command from the peripheral
In step 49-2, the telephone directory is automatically displayed on the display unit (screen) 17. That is, the telephone number search function is activated at the timing of receiving the password input request command. In step S50-2, the user searches the display unit 17 on which the telephone directory is automatically displayed for the corresponding registered password, and in step S51-2, enters the corresponding registered password into a key for confirming the password. Press etc. to confirm. Then, the mobile phone 10 stores the determined registration password in step S52 (step S3).
In 1), sent to the peripheral device via the RF unit 31 ₂ of the Bluetooth. As described above, the search for the registered password can be executed with some degree of automation.

FIGS. 8 and 9 show flowcharts of more detailed processing procedures when the mobile phone 10 to which the present invention shown in FIG. 6 is applied is used. The display state of the display unit 17 of the mobile phone 10 in the processing steps shown in FIGS.
And FIG. The processing procedure shown in FIGS. 8 and 9 is as follows.

First, in steps S61 and S62 shown in FIG. 8, the user performs a key operation for making the mobile phone 10 and the peripheral device (personal computer 50) function as Bluetooth. As a result, in the peripheral device, the CPU recognizes the key operation, and the

Of CPU23 is to identify the peripheral device based on the information from the RF unit 31 _2, and displays the information of the peripheral devices connectable to the display unit 17. For example, the mobile phone 10 performs display on the display unit 17 as shown in FIG.

Then, in step S65, when the user sees the display on the display unit 17 and presses a key (by operating the operation unit), a peripheral device (for example, a personal computer) to be connected is selected. , Step S66
In, CPU 23 generates a connection request command to the peripheral devices selected by the user, sends a connection request command to the peripheral device from the RF unit 31 ₂ via the BB unit 31 ₁ of the Bluetooth.

In the peripheral device, in step S67, the connection request command is received by the Bluetooth RF unit, and the CPU of the peripheral device analyzes the connection request command. Then, the CPU generates a password input request command, and transmits the password input request command to the mobile phone 10 from the RF unit via the Bluetooth BB unit. As described above, the connection request command is transmitted from the mobile phone 10 to the peripheral device, and the password input request command is returned from the peripheral device to the mobile phone 10 in response to the connection request command. During the waiting time, as shown in (C) in FIG.

In step S68, the mobile phone 10 transmits the password input request command to the Bluetooth R
Received through the BB unit 31 ₁ from the F 31 _2, it determines its password input request command by CPU 23 (recognition)
I do. Then, the CPU 23 displays on the display unit 17 a message prompting the user to input a password. For example, the mobile phone 10 displays a password input request on the display unit 17 as shown in FIG.

In step S69 shown in FIG. 9, the user who sees the display prompting for the input of the password presses a certain key (such as a key for starting the telephone directory search mode). The telephone 10 calls the telephone directory from the nonvolatile memory (NV memory) 16 and switches to the telephone directory search mode. Thereby, for example, as shown in FIG. 11B, the display unit 17 of the mobile phone 10
Register Password 17 ₂ and the peripheral device 17 ₁ which is corresponding to the registration password 17 ₂ is displayed is a form of paired.

Then, in step S70, the user performs a key operation while looking at the registered password displayed on the display unit 17, and selects a corresponding registered password from the telephone directory. Then, when the user finds a desired registration password, in step S71, the user determines the registration password as the contents of the telephone directory.

In response to such an operation by the user,
Mobile phone 10, in step S72, the extracted data of the determined telephone directory as the password, the password transmitting commands via the BB unit 31 ₁ of the Bluetooth, R
Sent from the F section 31 ₂ to the peripheral device. At this time, mobile phone 1
0 indicates that the authentication confirmation processing is being performed in the peripheral device as shown in FIG. For example,
Such a display is made until the connection is completed.

In the case of a conventional mobile phone, FIG.
As shown in FIG. 11A, when a password input request is made to the display unit 17, the user directly inputs the password in response to the request, and in this case, the user inputs the password in FIG.

7 is displayed directly on the display unit 17 as shown in FIG.

In steps S73 and S74, the peripheral device receives the transmitted password command and verifies whether the password is correct. If the password is correct, the peripheral device proceeds to step S75, and sends a command indicating that authentication has been completed (authentication OK) to the Bluetooth device.
To the mobile phone 10 via the RF unit. Then, the mobile phone 10 in step S76 is the CPU 23, receives the command via the BB unit 31 ₁ from the RF unit 31 ₂ of the Bluetooth, analyzing (authentication) to the command. Then, the mobile phone 10 confirms that a communication path has been established with the peripheral device, and that the authentication has been made (authentication O).
The display of K) is performed on the display unit 17. Thereafter, in step S77, transmission / reception (exchange) of the business card data and the like as described above is started between the mobile phone and the peripheral device.
For example, at this time, the mobile phone 10 performs a selection display on the display unit 17 so that the communication state can be changed, as shown in FIG.

On the other hand, if it is determined that the password is not correct as a result of the verification of the password in step S74, a process of failing to secure a communication path is performed in step S78. The above is the details of the processing procedure of the mobile phone 10 and the peripheral device.

The process corresponding to FIG. 7 showing the automated registration password search process is realized by the process shown in FIG.
