  By the way, when providing the above script to a mobile phone terminal device via a network, in order to reduce the possibility of executing unauthorized processing such as unintentional transmission of personal information by a malicious script, It is conceivable to restrict access from a script to a communication processing unit such as a communication unit.

  For this reason, the script is executed on a virtual execution environment (VM: Virtual Machine) provided in the mobile phone terminal device, and access to the communication processing unit is made an interface between this execution environment and lower processes. It is conceivable to carry out via (API: Application Program Interface).

  For example, when performing communication by the infrared communication unit via the API, the screen control right is transferred to a task different from the execution environment (for example, a lower native environment such as an OS), and the user regardless of the execution state of the script. It is conceivable to display an image requesting confirmation input of transmission / reception or to indicate that communication is being performed by infrared communication.

  If the amount of data transmitted / received by infrared communication increases or the communication speed due to the environment in the outside world increases, the communication time becomes longer. In such a situation, when displaying during communication by the native environment during communication by infrared communication, it takes time until the display of the screen by the script is resumed. For this reason, there is room for improvement from the viewpoint of responsiveness to the user.

  The present invention has been made in view of the above-described problems, and provides a mobile phone terminal device and a program providing system that can contribute to improvement of responsiveness during execution of a script using infrared communication. Objective.

Display means for displaying in response to a request, detection means for detecting a communication request by an infrared communication means from a script executed in a virtual execution environment, and a script when a communication request is detected by the detection means confirm display requesting confirmation of whether or not to perform infrared communication by independently processing performed, the after starting the infrared communication infrared communication means in accordance with the confirmation instruction for confirmation display, according to the script on the display means And display control means for permitting display.

Further, the program providing system according to the present invention includes a script providing apparatus that provides a script stored in the script storage means to the mobile phone terminal device, a receiving means that receives the script, and a pattern storage means that stores a predetermined pattern. And a script inspection apparatus having an inspection means for storing the script in the script storage means when the script received by the reception means does not correspond to the pattern stored in the pattern storage means, and a script acquired from the script providing apparatus. From a virtual execution environment to be executed, a display means for displaying in response to a request from a script via the virtual execution environment , an infrared communication means for performing infrared communication with other devices, and a script executed on the virtual execution environment Detecting means for detecting a communication request by infrared communication means, and detecting means Therefore when a communication request is detected, performs a confirmation display requesting confirmation of whether or not to perform infrared communication by the processing which is executed independently of the script, the infrared communication means in accordance with the confirmation instruction for confirmation display after that initiated the infrared communication, characterized by comprising a mobile telephone terminal apparatus and a display control means for permitting the display by the script on the display unit.

  In the present invention, when a communication request is detected by the detection means by the display control means, a confirmation display requesting confirmation of whether or not to perform infrared communication by a process executed independently of the script is performed, and the confirmation is performed. After the infrared communication is started according to the display, the script can be displayed. For this reason, even during communication by the infrared communication means, it is possible to perform display in accordance with the execution of the script, which can contribute to improvement of responsiveness to the user.

  The present invention can be applied to a mobile communication system that can provide a script to a mobile phone terminal device via a wireless communication network and execute the script on the mobile phone terminal device.

(overall structure)
A mobile communication system according to an embodiment of the present invention includes a script providing device 10 that provides an application program (script) described in a script language that can be executed in a mobile phone terminal device, as shown in FIG. A wireless communication network 30 connected to the script providing device 10 via a network 20 such as the Internet, and a mobile phone terminal device 40 capable of acquiring a script from the script providing device 10 via the wireless communication network 30 are provided.

  The script providing apparatus 10 includes a database (DB) 11 composed of a hard disk drive (HDD) and the like, and an HTTP server 12 that supplies a script stored in the DB 11 to the mobile phone terminal device 40.

  The mobile phone terminal device 40 can execute a script described in a script language such as Java (registered trademark), for example. As shown in the figure, for example, the script includes an archive file 11A (11B) obtained by combining the script body and data used when executing the script, and an information file 11a indicating information on the archive file 11A (11B). (11b) is stored in the DB 11 as a combination. The archive file 11A (11B) is composed of a jar file [Java (registered trademark) archive file] in which the script body and data such as images and sounds used when executing the script are compressed and encoded together, and the information file 11a (11b). ) From jad [Java (registered trademark) descriptor file] in which information indicating the size of the jar file, the version of the script, the creator of the script, the address of the data section 52 such as URL (Unified Resource Locator), etc. is stored. Composed.

(Mobile phone terminal configuration)
The cellular phone terminal device 40 includes a radio frequency (RF) unit 41 that performs processing such as level adjustment, modulation / demodulation or timing control of a high frequency signal, and a communication control unit 42 that performs communication control between the radio communication network 30. A speech processing unit 43 that executes speech processing such as encoding / decoding of an audio signal, a speaker 44, a microphone 45, and an information processing device such as another mobile phone terminal device having an infrared communication function. An infrared communication unit 46 for performing infrared communication between them, an operation input unit 47 for inputting an instruction from the user, a display unit 48 for displaying a display image for the user, a memory 49 for storing a control program, data, and the like And a control unit 50 configured by an MPU or the like for controlling the operation of the entire mobile phone terminal device 40, a vibrator 59 for vibrating the mobile phone terminal device 40, and the like.

  The control unit 50 executes, for example, a control program stored in the memory 49, from an operating system (OS) 51 that manages processing time or input / output of the memory 49 and MPU, an operation input unit 47, and the like. An input control unit 52 for controlling input, a display control unit 53 for controlling output to the display unit 48, the speaker 44, and the like, a mobile browser terminal such as a Web browser 91, a mail client 92, various settings 93, a telephone directory, a scheduler, etc. It functions as a script execution environment 55 for executing an application (native application) 54 pre-installed in the device 40 and a script 56 provided from the script providing device 10 described above.

(Script inspection device)
In this mobile communication system, the script provided by the script providing apparatus 10 is not directly stored in the DB 11 from the information processing apparatus (development machine) 60 such as a personal computer that creates the script, but by the script inspection apparatus 70. It is stored in the DB 11 after confirming the presence or absence of a script that performs illegal processing.

  The script inspection apparatus 70 includes a reception unit 71 that receives a script from the development machine 60, a pattern file storage unit 72 that stores a pattern file that defines a script that performs unauthorized processing, and an inspection of the script that the reception unit 71 receives. And a script inspection unit 73. When the script from the development device 60 is supplied via the receiving unit 71, the script checking unit 73 determines whether the supplied script satisfies the condition of the pattern file stored in the pattern file storage unit 72. The script is stored in the DB 11 only when the pattern file condition is not met.

  Examples of fraudulent processing include, for example, accessing native application data without confirming with the user, or transmitting data without confirming with the user. It can be detected based on whether or not a predetermined pattern exists.

  Thereby, in this mobile communication system, the safety of the script executed in the mobile phone terminal device 40 is improved compared to a system that can provide the mobile phone terminal device 40 with a script that does not check the contents. Can be improved.

(Infrared communication function)
By the way, in infrared communication via the infrared communication unit 46 of the mobile phone terminal device 40, for example, a standard (physical layer: IrPHY (IrSIR :), data specified by IrDA as a lower layer protocol that defines the format of an infrared signal, etc. The link layer: IrLAP, IrLMP, the transport layer: TinyTP, and IrOBEX is used as the protocol for the upper layer (session layer) that defines the transfer of objects (data such as files). As shown in the figure, the infrared communication unit 46 is configured separately from the control unit 50, the script execution environment 55 controls the upper layer such as IrOBEX, and the infrared communication unit 46 controls the lower layer such as IrDA. By doing so, the processing load on the control unit 50 can be reduced.

(Script execution environment)
For example, as shown in FIG. 2, the script execution environment 55 defines a CLDC (Connected Limited Device Configuration) 55a which is one of configurations of Java (registered trademark) ME (micro edition), and a profile on the CLDC 55a. It can be configured to include a Mobile Information Device Profile (MIDP) 55b and an extended API 55c that defines an API (Application Program Interface) such as infrared communication.

  The CLDC 55a provides a core library for processing basic operations and a KVM (K Virtual Machine) that is a virtual machine. The MIDP 55 b provides the script 56 with an environment such as a GUI (Graphical User Interface) such as an image displayed on the display unit 48 and event processing. The extended API 55c provides a unique API such as a provider of the mobile phone terminal device 40 or a provider of the wireless communication network 30 that is not defined in MIDP. Processing such as a communication request from the script 56 to the infrared communication unit 46 is processed via the extended API 55c.

  In the extended API 55c, communication-related processing (method) by the above-described IrOBEX is defined. In IrOBEX, two devices that perform communication operate as an OBEX client and an OBEX server, and perform communication according to their functions. The selection of whether to be an OBEX client or an OBEX server is set according to the function executed by each device.

  The extended API 55 c provides several methods for the script 56. For example, a connection method is defined as a method by which the script 56 requests the start of infrared communication. When the script 56 calls this connection method, the extended API 55c instructs the infrared communication unit 46 to connect a lower layer connection with another device. When the connection is connected, the connection is set as a return value. Data is supplied to the script 56.

  Further, after the connection is set, a GET method is defined as a method for requesting data from the client-side device to the server-side device, and the return value for the script 56 that called this GET method is the server-side device. Data supplied from. Also, a PUT method is defined as a method for transmitting data from the client side device to the server side device, and the return value for this PUT method is a value indicating whether or not the data transmission was successful.

  As described above, by defining communication by IrOBEX in the extended API 55c, the script 56 can communicate with another information processing apparatus or the like by infrared communication.

(Get script)
When requesting a script to the script providing apparatus 10, first, for example, the Web browser 91 has an HTML (Hyper Text Markup Language) format having data such as a list of scripts that the script providing apparatus 10 can provide to the HTTP server 12. Request data for The web browser 91 displays an image corresponding to this data on the display unit 48, and when the user operates the operation input unit 47 to select a script requested to the script providing apparatus 10, the web browser 91 displays the instructed script. The HTTP server 12 is requested to transmit a jad file (information file 11a or the like) corresponding to.

  The HTTP server 12 reads the requested jad file from the DB 11 and transmits it to the mobile phone terminal device 40. When the web browser 91 is supplied with the jad file, the web browser 91 confirms information such as the capacity and version of the jar file in the jad file, and if the jar file can be executed by the mobile phone terminal device 40, the user Confirm whether or not to acquire a script (jar file). In response to this, when the user instructs acquisition of the script, the Web browser 91 requests the HTTP server 12 to transmit the jar file, and the jar file supplied from the HTTP server 12 via the wireless communication network 30 is stored in the script in the memory 49. Store in the storage unit 49a.

(Run script)
A plurality of scripts can be stored in the script storage unit 49a, and a script selected by the user from a list of executable scripts can be executed.

(Screen display restrictions when executing scripts using infrared communication)
By the way, the OS 51 uses the switching unit 51a to switch the image that the display processing unit 51c supplies to the display control unit 53 in accordance with the status of the processing being executed. For example, when waiting or executing a native application such as the Web browser 91 and the mail client 92, a display image (native screen) generated by the display processing unit 51c according to an instruction from the native application or the OS 51 is displayed on the display unit 48, and a script execution environment is displayed. When the script 56 is executed by 55, a display image (script screen) generated by the display processing unit 51c is displayed on the display unit 48 according to an instruction from the script 56 supplied through the drawing process of the CLDC 55a.

  Further, the OS 51 performs infrared communication to the user when starting communication by the infrared communication unit 46 in order to prevent the transmission of data unintended by the user by a script or the like that performs unauthorized processing. It is made to choose whether or not.

  For example, as shown in FIG. 3, the OS 51 instructs the switching unit 51a to display a script screen when the execution of the script is started (S1), and the monitoring unit 51b that monitors the execution state of the script 56 A start request for infrared communication from the script 56 to the extended API 55c is monitored (S2). When the monitoring unit 51b detects the infrared communication start request, the OS 51 instructs the switching unit 51a to display the native screen on the display unit 48 (S3), and starts the infrared communication, for example, as shown in FIG. An image 101 indicating that the image is displayed is generated and displayed on the display unit 48 via the display control unit 53.

  When the user selects to shift to the infrared communication mode for this display image (S4), the OS 51 instructs the switching unit 51a to display the script screen on the display unit 48 (S1), and the infrared communication unit. 46 shifts to a state where communication according to 46 can be performed.

  In the cellular phone terminal device 40, an image indicating that infrared communication is being waited and infrared communication is being performed is generated on the script 56 side. When the mode shifts to the infrared communication mode and the script screen is displayed, an image 102 indicating that the script 56 is waiting for the infrared communication generated by the script 56 is displayed on the display unit 48, for example, as shown in FIG. . Further, during infrared communication, for example, as shown in FIG. 6, an image 103 generated by the script 56 indicating that infrared communication is being performed is displayed on the display unit 48. 5 and 6 show an example in which characters are displayed as the images 102 and 103. If the image generation processing is defined in the script 56 instead of the characters, the script 56 generates the image. It is also possible to display such images.

  Further, the OS 51 displays the display 110 indicating the radio wave intensity as shown in the upper right of the screen in FIG. 4 before shifting to the mode for performing infrared communication according to the detection output of the monitoring unit 51b, for example. When the mode is shifted to the infrared communication mode, the display is switched to the display 111 indicating the infrared communication mode as shown in the upper right of the screens of FIGS. 5 and 6, and the infrared communication mode is displayed.

(effect)
In a system configured to be able to provide the mobile phone terminal device 40 with a script that does not check the contents, there is a relatively high possibility that the mobile phone terminal device 40 executes an unauthorized process script. From the viewpoint, in addition to the confirmation before starting the infrared communication, it is desirable to display to the user that the infrared communication is being performed on the native screen during the infrared communication.

  However, as described above, in this mobile communication system, the script executed by the mobile phone terminal device 40 as compared with the system configured to be able to provide the mobile phone terminal device 40 with a script that does not check the contents. Therefore, it is considered sufficient to confirm with the user before starting the infrared communication as described above. Therefore, after the user selects to shift to the infrared communication mode, as described above, the script screen can be switched and an arbitrary image can be displayed by the script.

  Depending on the processing status of the counterpart device that performs infrared communication, the conditions of infrared communication, and the like, the standby state of infrared communication or the state of infrared communication may last for a long time. In such a situation, if the OS 51 or the native application displays an image indicating that infrared communication is waiting or infrared communication is being performed, the monotonous image continues to be displayed, and the user gets bored. It can be considered. Further, since these images are the same regardless of the type of the script 56, there is room for improvement from the viewpoint of responsiveness to the user.

  On the other hand, in this mobile phone terminal device 40, since the image generated by the script 56 can be displayed during standby for infrared communication or during infrared communication, the standby state or the state during infrared communication is long. Even if it continues, the responsiveness with respect to a user can be improved by displaying the image relevant to the script 56. FIG.

(Concrete example)
When the execution of the script using the infrared communication is started, for example, as shown in FIG. 7, the OS 51 gives the screen 56 the screen display right of the display unit 48 to the script 56 (S101). After displaying the above, for example, an input request screen as shown in FIG. 8 and FIG. 9 is displayed and the user is requested to input data to be transmitted to the counterpart device (S102). The script 56 selects an operation as an OBEX client or an OBEX server according to, for example, input data, requests the above-described extended API 55c to start infrared communication with another device, and performs infrared communication with another device. It waits for a lower layer connection to be established (S103).

  When the above-described monitoring unit 51b detects this request, the OS 51 causes the switching unit 51a to select the display of the native screen, and requests the user to select whether or not to start infrared communication, for example, as shown in FIG. A confirmation screen is displayed (S201).

  In response to this, when the user instructs the start of infrared communication, the OS 51 instructs the switching unit 51a to select display of the script screen, and notifies the script 56 via the extended API 55c (S203). Furthermore, the OS 51 instructs the infrared communication unit 46 to set a connection with the counterpart device (S204).

  On the other hand, when notified that the user has input a confirmation instruction (S104), the script 56 displays an image indicating that it is waiting for infrared communication, for example, as shown in FIG. 6 (S105). (S106).

  In the state of waiting for infrared communication, when the user faces the light emitting / receiving unit of the infrared communication unit 46 of each mobile phone terminal device 40, the communication process shown in FIG. 11 is started, and the negotiation process is performed between the infrared communication units 46. Is executed.

  When the negotiation is successful (IrDA Negotiation Completed) and the infrared communication unit 46 sets a lower layer connection with the counterpart device, the OS 51 notifies the script 56 to that effect (S204). In response to this notification, the script 56 instructs the OS 51 via the extended API 55c to communicate with the upper layer according to IrOBEX (S107). Further, the script 56 waits for the end of communication (S108 to S109) while displaying an image indicating that communication is in progress on the display unit 48 (S108).

  When there is an instruction from the script 56 as described above, the OS 51 causes the infrared communication unit 46 to perform communication processing in IrOBEX (S205). In this communication process, for example, as shown in FIG. 11 described above, first, a connection request (CONNECT request) using the CONNECT method is transmitted from, for example, a device on the OBEX client side to a device on the server side. When there is a response (CONNECT response) from the client, the script 56 executed on the client side device transmits data to the server side device from its own device by the PUT method (PUT request), and then the GET method Data from the server side device is acquired by (GET request).

  When the communication using IrOBEX is completed as described above, the script 56 transmits a disconnection request (DISCONNECT request) using the DISCONNECT method, and when there is a response to this, the OS 51 terminates the connection to the infrared communication unit 46 by infrared communication. (IrDA Connection Finished), and notifies the script 56 to that effect (S206).

  When transmission / reception of data to / from other devices via infrared communication is completed, the script 56 executes processing corresponding to the received data, for example (S110), and displays the processing result on the display unit 48 (S111).

  During the infrared communication as described above, since the switching unit 51a selects the display of the script screen as described above, the script 56 is, for example, shown in FIG. 12 (a) to FIG. ), An image corresponding to the content of the process being executed can be displayed. For example, in the case of the script 56 that performs compatibility fortune-telling, the image of FIG. 10A is displayed at the first execution of S109, and the image of FIG. Are displayed alternately. Thereby, the image of the flower fortune-telling in which the petals fall one by one from the image of the flower can be displayed, and the image related to the compatibility fortune-telling that is the processing content of the script 56 can be shown to the user. This can contribute to maintaining the user's interest or concentration during infrared communication.

  Thus, by displaying the image according to the content of the script 56 during infrared communication, the responsiveness to the user can be improved, and the user interface can be improved.

(Modification)
In the first embodiment described above, when the infrared communication is requested from the script 56, the OS 51 displays a confirmation screen (native screen) for the user. For example, while waiting for infrared communication or infrared communication The native screen may be displayed in any of them. Even in this way, the script screen can be displayed during infrared communication or standby for infrared communication, which can contribute to improvement of responsiveness to the user.

  Alternatively, depending on the setting, the operation can be switched so that the confirmation screen is displayed only when there is a request for starting infrared communication, or the confirmation screen is displayed during standby or infrared communication other than when the start request is made. It can also be configured as follows.

  Further, the mobile phone terminal device 40 may be configured such that the security level can be set, and the state in which the confirmation screen is displayed can be switched according to the security level.

  In the above description, an example of processing when the script 56 uses infrared communication by the infrared communication unit 46 has been described. However, a method that uses communication by the communication control unit 42 is defined in the extended API 55c, and the script 56 The present invention can also be applied to a case where 56 is configured to be able to communicate with other devices connected via the network 20.

  In such a configuration, for example, when the script 56 requests a network connection via the extended API 55c, the user confirms whether or not to perform communication through the native screen, and after the network connection is instructed by the user, By displaying the script screen, it is possible to contribute to improvement of responsiveness to a user who is communicating via a network connection, as described above.
