For example, the takeover factor is an event indicating that the remaining capacity of the built-in battery in the takeover source information terminal device has fallen below a certain value, or an event in which supply power from the external power supply in the takeover source information terminal device is insufficient. It is.
Also, for example, the takeover destination continuation constraint is an output restriction caused by a difference in resolution on the display screen between the takeover source information terminal device and the takeover destination information terminal device, or information on the takeover source information terminal device and the takeover destination Output restrictions due to differences in functions or performance of the application with the terminal device, and viewing restrictions due to differences in rendering functions of the Internet browser application installed in the takeover source information terminal device and the takeover destination information terminal device It is.

  The present invention is also directed to a takeover destination information terminal device that takes over an application execution state or content use state from a takeover source information terminal device. In order to achieve the above object, the takeover destination information terminal device of the present invention receives from the takeover source information terminal device a notification indicating a state in which the takeover factor in the takeover source information terminal device has been resolved, A notification processing unit that executes a predetermined process corresponding to the notification, and a takeover control unit that inquires whether to reproduce the application execution state or the content usage state at the time when the previous takeover occurred.

  In takeover information request step S2004, in the information terminal device B200, the takeover control unit B205 requests the information terminal device A100 to transmit takeover information via the transmission / reception unit B206, and the takeover information of the information terminal device A100 is transmitted. Waiting for reception.

  In the takeover factor confirmation step S1004, in the information terminal apparatus A100, the takeover control unit A105 receives a request for takeover information from the takeover destination terminal via the transmission / reception unit A108, and requests the takeover factor management unit 109 to confirm the takeover factor. To do. The takeover factor management unit 109 confirms whether or not the takeover factor is caused by the inability to continue using the information terminal device A100, and returns the result to the takeover control unit A105. Specifically, the takeover factor management unit 109 makes an inquiry to the power supply management unit 110 to check whether the battery is dead. The power management unit 110 confirms the power state in the power unit 111, and if the power is not enough to continue the execution of the application (for example, browsing processing in the Internet browser), information indicating battery exhaustion is taken over as the takeover factor management unit 109. Return to.

  In the above description, the takeover factor is described as being caused by the power supply as a specific example. However, application processing is taken over by the information terminal device B200 that prevents the application terminal from continuing to browse and use the information terminal device A100. Other examples may be used as long as they are factors.

In the takeover destination continuation constraint determination step S1005, in the information terminal device A100, the content that the takeover processing unit A105 executes in the application processing unit A102 with respect to the takeover destination continuation constraint determination unit 112 is the same in the information terminal device B200. Judge whether you can continue to use without inconvenience restrictions.
Specifically, for example, when browsing content on a network with an Internet browser, if the layout is optimized for a large screen display such as a large screen PC or a tablet terminal, the small screen of the portable terminal Visibility may be impaired because a part of the image is enlarged, and by comparing the display resolution with the display size (width or height) described in the HTML file or CSS file of the display target content , Display constraints can be detected. Also, depending on the rendering engine, it is possible to detect a phenomenon in which browsing and use cannot be continued due to an event in which the Flash content or embedded video is not played back.

  In the processing branch step S1006 based on the takeover destination continuation constraint, in the information terminal device A100, the takeover processing unit A105 determines that the information terminal device B200 imposes restrictions on the continuous use of the application as a result of the processing in the takeover destination continuation constraint determination step. If so (S1006: Yes), the processing of the notification reservation determination step S1007 is continued. Further, when the takeover processing unit A105 determines that no restriction is imposed on the continuous use of the application in the information terminal device B200 as a result of the takeover destination continuation constraint determination step (S1006: No), the takeover information Processing subsequent to the generation step S1008 is continued.

In notification reservation determination step S1007, in information terminal apparatus A100, takeover processing unit A105 recovers from a state where use cannot be continued if the result of takeover factor confirmation step S1004 is caused by use not being continued (takeover factor). ) Is reserved, the state notification unit 113 is reserved for notification reservation for notifying the information terminal device B200 of the recovery state. The state notification unit 113 receives the notification reservation and requests the power supply management unit 110 to issue a notification of charging completion when it reaches a certain value indicating completion of charging.
More specifically, when it is determined that the battery has run out as a result of the takeover factor confirmation step S1004, the takeover processing unit A105, when detecting that the device has been charged, informs the information terminal device B200 to “charge”. A reservation is made to the state notification unit 113 to notify that “completion” has been completed. Note that if it is not caused by the inability to continue using such as running out of battery, it is assumed that the user has taken over to the takeover destination terminal 200, and no notification is reserved when charging is completed. In addition, even when there is no restriction on continuous use at the takeover destination, the user can continue to use the application (more specifically, browsing with a browser, etc.) without any problem on the information terminal device B200, so that charging is completed in the same way. We do not make time reservations.

  In takeover information generation step S1008, the information terminal device A100 generates takeover information 107 for the takeover information generation unit 106 to transmit to the information terminal device B200 in response to a control request from the takeover processing unit A105. Specifically, for example, in the case of an Internet browser, the takeover information generation unit 106 sends to the application processing unit A102 the source file of the currently displayed content or the rendered cache data, the browsing history, and the favorite site. Information including at least one of a link and a login state of a user such as cookie is acquired, and data is compressed to be transmitted and generated as takeover information 107 for transmission.

  In the takeover information transmission step S1009, in the information terminal device A100, the takeover processing unit A105 transmits the takeover information 107 generated in the takeover information generation step S1008 to the information terminal device B200 via the transmission / reception unit A108.

  In the takeover information receiving step S2005, in the information terminal apparatus B200, the takeover control unit B205 receives the takeover information 107 transmitted in the takeover information transmitting step S1009 via the transmission / reception unit B206 and stores it in the internal storage unit ( 207 in FIG.

  In the application end step S1010, in the information terminal apparatus A100, the takeover control unit A105 ends the process of the application processing unit A102 being executed along with the end process of the takeover process. Specifically, for example, in the case of an Internet browser, the takeover control unit A105 requests the application processing unit A102 to end the Internet browser after the takeover information transmission step S1009 is normally completed.

  In response to the termination request, the application processing unit A102 executes disconnection processing when the external connection unit A103 is connected to the network, and terminates the Internet browser. At this time, a standard display screen displayed by the OS or the like mounted on the information terminal device A100, such as a desktop screen, is displayed on the display unit A. Further, the takeover control unit A105 disconnects the communication with the information terminal device B200 via the transmission / reception unit A108 and ends the takeover process.

  In the charging step S1011, in the information terminal device A100, when the power supply unit 111 is connected to the charging device 400 and transmitted by the user, the power management unit 110 executes the charging control. When the power management unit 110 detects that the state of the power supply unit 111 has reached a certain value indicating completion of charging, the power management unit 110 notifies the state notification unit 113 of the completion of charging.

  In the takeover information processing step S2006, the information terminal apparatus B200 controls the takeover information processing section 208 of the takeover control section B205 to reproduce a state equivalent to the application of the information terminal apparatus A100 using the received takeover information 207. To do. Specifically, in the case of an Internet browser, for example, the takeover control unit B205 provides the takeover information 207 received via the transmission / reception unit B206 to the takeover information processing unit 208 to execute an application using the takeover information 207. Request.

  The takeover information processing unit 208 expands the compressed takeover information 207 into an available data state. Further, the takeover information processing unit 208 provides data of content to be displayed to the Internet browser executed by the application processing unit B202 via the takeover control unit B205, and requests display of the content. The data of the content to be displayed is the content that was displayed when the information terminal device A100 took over, so that the content displayed on the information terminal device A100 can be continuously displayed on the information terminal device B200. Furthermore, the takeover information processing unit 208 provides the application processing unit B202 with at least one of cache data included in the takeover information 207, a browsing history, a link to a favorite site, and a user login state such as cookie.

  Thereafter, the user can continuously use the application reproduced in the takeover information processing step S2006 in the application use continuation step S2007. Specifically, for example, in the case of an Internet browser, it is possible to continue using the browser browsing state, history usage state, and the like displayed on the information terminal device A100 on the information terminal device B200.

  Next, the inter-information terminal notification method provided by the present invention will be described. FIG. 5 is a flowchart showing procedures of the inter-information terminal notification method and the inter-information terminal re-takeover method executed by the information terminal device according to the embodiment of the present invention.

  The information terminal device notification method and the information terminal device re-takeover method shown in FIG. 5 are the steps processed by the information terminal device A100, the charging step S3001, the charging completion determination step S3002, the notification reservation state confirmation step S3003, the notification destination terminal. A confirmation step S3004, a charging completion notification step S3005, a takeover request confirmation step S3006, an application activation step S3007, a takeover information reception step S3008, a takeover information processing step S3009, and an application use continuation step S3010 are provided. Further, in the inter-information terminal notification method and the inter-information terminal re-takeover method shown in FIG. 5, the information terminal device B 200 processes as charging completion notification reception step S4001, user leaving processing step S4002, and takeover execution confirmation step S4003. , A takeover information generation step S4004, a takeover request step S4005, and a takeover information transmission step S4006.

  In charging step S3001, in information terminal device A100, power supply unit 111 is connected to charging device 400 by the user, and power supply unit 111 is in a state of charging. This charging step S3001 corresponds to the charging step S1011 in the above-described information terminal device notification reservation method. In the charging step S3001, in the information terminal device A100, the state notification unit 113 is further in a state of making a reservation for notifying the information terminal device B200 of the completion of charging by the processing of the information terminal device notification reservation method. .

  In the charging completion determination step S3002, in the information terminal apparatus A100, the power management unit 110 confirms whether the charging state of the power supply unit 111 has reached a certain value that satisfies the charging completion. Further, when the charging state of the power supply unit 111 has reached a certain value that satisfies the charging completion, the power management unit 110 notifies the state notification unit 113 that the charging is complete, and next notification reservation state confirmation step S3003. The process is shifted to (S3002: Yes). Moreover, the power management part 110 continues a charge condition, when the charge condition of the power supply part 111 has not reached the fixed value which satisfy | fills charge completion (S3002: No).

  In the notification reservation state confirmation step S3003, in the information terminal device A100, the state notification unit 113 receives a notification indicating the completion of charging from the power management unit 110 and notifies other devices of the device state of the information terminal device A100. Check if it is in a reserved state. If the state notification unit 113 is in the notification reservation state, the state notification unit 113 proceeds to the next notification destination terminal confirmation step S3004 (S3003: Yes). If it is not in the notification reservation state, the charging is completed as it is, and the process is terminated (S3003: No).

  In the notification destination terminal confirmation step S3004, in the information terminal device A100, the state notification unit 113 confirms the information of the notification destination device held internally. Specifically, when the communication method to be notified is IP communication such as a wireless LAN, the notification destination IP address of the information terminal device B200 acquired when the notification is reserved is confirmed. Moreover, you may further confirm terminal identifiers, such as apparatus ID, for identifying whether information destination IP address is the information terminal device B200 which should actually be notified.

  In the charging completion notification step S3005, in the information terminal device A100, the state notification unit 113 transmits a charging completion notification to the notification destination acquired in the notification destination terminal confirmation step S3004. In the charging completion notification receiving step S4001, in the information terminal device B200, the transmission / reception unit B206 receives the charging completion notification and passes the charging completion notification and the transmitted notification content to the notification processing unit 209.

  In the user notification process S4002, in the information terminal device B200, the notification processing unit 209 passes the charging completion notification and the transmitted notification content to the takeover control unit B205 according to the notification content. The handover control unit B205 informs the user by displaying on the display unit B204 that the charging of the information terminal device A100 is completed based on the notification content. Specifically, when the device name set by the user for the information terminal device A100 is “tablet” as the information included in the notification content or the takeover information 207, the takeover control unit B205 displays the display unit B204 which is a display. Displays a dialog stating that the tablet is fully charged.

  In takeover execution confirmation step S4003, in the information terminal device B200, the takeover control unit B205 inquires of the user whether to execute the application takeover to the information terminal device A100 via the display unit B204. At this time, the takeover control unit B205 includes the reproduction of the state of the information terminal device A100 at the time when the previous takeover occurred from the contents of the takeover information 207 in the previously executed information terminal device notification reservation process. Is output to the display unit B204.

  Specifically, the takeover control unit B205 displays a confirmation dialog “The tablet has been charged. Do you want to take over the process?” On the display unit B204, which is a display. Furthermore, as an answer method to be input by the user, for example, three options of “display the state taken over from the previous tablet”, “take over the current state to the tablet”, and “do not take over to the tablet” are displayed. Allow the user to select one. Here, when the user selects “display the state taken over from the previous tablet”, the takeover control unit B205 can reproduce the output state at the time of taking over from the previous information terminal device A100 from the takeover information 207. The process proceeds to the next takeover information generation step S4004 (S4003: “with takeover”). Further, when the user selects “take over the current state to the tablet”, the next takeover is performed so that various application states of the current information terminal device B200 can be continuously used even after retaking over to the information terminal device A100. The process proceeds to the information generation step S4004 (S4003: “with handover”). If the user selects “Do not take over to tablet”, the confirmation dialog display is deleted as it is, and the notification process is terminated (S4003: “No takeover”).

The above processing steps (S3005 and S4003) are processing steps of the inter-information terminal device notification method performed between the information terminal device A100 as the takeover source terminal and the information terminal device B200 as the takeover destination terminal.
Subsequent processing steps (S3006 and S4004) describe an inter-information terminal apparatus re-takeover method executed when the information terminal apparatus A100 functions as a re-takeover destination terminal and the information terminal apparatus B200 functions as a re-takeover source terminal. To do.

  Accordingly, in the subsequent processing steps (S3006 and S4004), the information terminal device A100 functions as a takeover destination terminal by further including the configuration shown by the information terminal device B200 in FIG. 3, and the information terminal device B200. Is assumed to function as a takeover source terminal by further comprising the configuration shown by the information terminal device A100 in FIG. The functions and processing contents of the constituent blocks further provided in the information terminal devices A100 and B200 are as described above. Based on the above, the subsequent processing steps (S3006 and S4004) will be described in detail.

In the takeover information generation step S4004, the retakeover source terminal (information terminal device B200) takes over information 207 for the takeover information generation unit to transmit to the retakeover destination terminal (information terminal device A100) in response to a control request from the takeover processing unit. Is generated.
Specifically, for example, in the case of an Internet browser, the takeover information generation unit of the retakeover source terminal provides the application processing unit with the source file or rendered cache data of the currently displayed content, browsing history, favorite Information including at least one of a link to the site and a login state of the user such as cookie is acquired, and data compression is performed for transmission, and the information is generated as takeover information 207.

Furthermore, the takeover information generation unit of the retakeover source terminal, when the user selects “display the state taken over from the previous tablet” in the takeover execution confirmation step S4003, the previous takeover source terminal (retakeover destination terminal) The takeover information is generated so that the output state at the time of takeover can be reproduced from the contents of the takeover information taken over from).
More specifically, in the case of an Internet browser, for example, at least one of the display URL, display content, cache data, and cookie data at the time when the previous takeover occurred is first displayed at the takeover source terminal (re-transfer destination terminal). Configure takeover information to output to

Further, the takeover information generation unit of the takeover source terminal, when the user selects “take over the current state to the tablet” in the takeover execution confirmation step S4003, the current takeover destination terminal (retakeover source terminal). The takeover information is generated so that the various application states can be continuously used even after the takeover is performed again to the takeover source terminal (retakeover destination).
More specifically, for example, in the case of an Internet browser, the takeover information generation unit of the retakeover source terminal displays the source file of the currently displayed content or the rendered cache data, the browsing history, the link to the favorite site, and Information including at least one of the login states of the user such as cookie is acquired, and is compressed as data to be transmitted to the application processing unit and generated as takeover information.

  In the takeover request step S4005, in the retakeover source terminal, the takeover control unit transmits a takeover request to the retakeover destination terminal via the transmission / reception unit. Furthermore, if the takeover control unit detects that the request cannot be received at the re-transfer destination terminal via the transmission / reception unit, or if it receives a response indicating that the request is rejected, it does not continue the subsequent re-takeover process. End (not shown).

  In the takeover request confirmation step S3006, in the retakeover destination terminal, the takeover control unit confirms whether the takeover request from the retakeover source terminal has been received via the transmission / reception unit. Further, when the takeover control unit receives a takeover request from the re-takeover source terminal, the takeover control unit continues the processing after the application activation step S3007 (S3006: Yes). Also, when the takeover control unit does not receive a takeover request from the re-takeover source terminal (when it has not received as a result of executing the waiting for reception for a certain period of time), the takeover process is skipped and the notification process is performed as it is. The process ends (S3006: No).

In the application activation step S3007, in the retakeover destination terminal, the takeover control unit determines the application to be activated from the information content received in the takeover request confirmation step S3006. Further, the takeover control unit requests the application processing unit to start the application to be started as a result of the determination.
Specifically, in the case of an Internet browser, for example, the takeover control unit determines from the information content received in the takeover request cabinet member step S3006 that the application to be started up for taking over is an Internet browser, and sends it to the application processing unit. It requests the Internet browser to start. The application processor receives an application activation request from the takeover controller and activates the Internet browser.

  In the takeover information transmission step S4007, in the retakeover source terminal, the takeover processing unit transmits the takeover information 207 generated in the takeover information generation step S4006 to the retakeover destination terminal via the transmission / reception unit.

  In the takeover information reception step S3008, in the re-takeover destination terminal, the takeover control unit receives the takeover information 207 transmitted in the takeover information transmission step S4006 via the transmission / reception unit, and stores it in the internal storage.

  In the takeover information processing step S3009, the takeover information processing unit of the takeover control unit controls the retakeover destination terminal to reproduce a state equivalent to the application of the takeover source terminal using the received takeover information 207.

  Specifically, in the case of an Internet browser, for example, the takeover control unit provides the takeover information 207 received via the transmission / reception unit to the takeover information processing unit, and requests execution of an application using the takeover information. The takeover information processing unit expands the compressed takeover information 207 into a usable data state. Further, the takeover information processing unit provides the content data to be displayed to the Internet browser executed by the application processing unit via the takeover control unit, and requests display of the content. The data of the content to be displayed is the content that was displayed when the retakeover source terminal took over, so that the content displayed at the retakeover source terminal can be continuously displayed at the retakeover destination terminal. Further, the takeover information processing unit provides the application processing unit with at least one of cache data included in the takeover information 207, a browsing history, a link to a favorite site, and a user login state such as cookie.

  Thereafter, the user can continue to use the application reproduced in the takeover information processing step S3009 in the application use continuation step S3010. Specifically, in the case of an Internet browser, for example, it is possible to continue to use the browser browsing state, history usage state, and the like displayed on the retakeover source terminal at the retakeover destination terminal.

Note that the state management and notification contents of the notification reservation and the information of the notification destination terminal that are internally held by the state notification unit 113 may be stored in a non-volatile area so that the contents can be retained even if the power is cut off due to battery exhaustion. desirable.
The constant value that satisfies the completion of charging is a constant value that can supply an amount of power that guarantees that the application desired by the user operates for the time desired by the user, and is a value determined in advance for each application or terminal. Alternatively, a value that can be freely set by the user may be used.
In the information terminal apparatus A100, the external connection unit A103 and the transmission / reception unit A108 may have the same module configuration when using the same communication method. Similarly, the external connection unit B203 and the transmission / reception unit B206 in the information terminal device B200 may have the same module configuration when using the same communication method.
Further, the display unit may not be a display, but may be an output of the kind notified to the user by sound output such as a speaker.
Further, since the same information can be obtained at any stage between steps S1001 to S1009 in the takeover information generation step S1008, the processing may be switched.
In addition, since the same information can be obtained in the takeover information generation step S4004 at any stage up to step S4006, the processing may be switched.

As described above, according to the information terminal device according to the embodiment of the present invention, the user can continue using the application device state to another terminal device without stopping due to the terminal device being used being out of charge. When it is detected that the output results are different due to functional differences and performance differences such as resolution and rendering engine support for each terminal device, a charging completion notification is received from the terminal device used so far. It is possible to quickly know that the terminal device that has been used again can be browsed.
Further, in another terminal device that does not need to receive this notification, there is no inconvenience due to the notification of the completion of charging from a different terminal device.

  Furthermore, according to the information terminal device according to an embodiment of the present invention, when the user receives a notification of charging completion from the takeover source terminal, the display state at the time of taking over from the previous takeover source terminal is automatically restored. Can be made. As a result, the user can resume browsing with an application, particularly a browser, from the state at the time of taking over to another terminal without stopping.
