- the “locking service” is an electronic device having a locking function and is a service for locking in real time or at a designated date and time. The user can specify an activation request by moving the cursor to a desired service and pressing a decision button.
- the electronic device 12 that has received the instruction from the application activation arbitration device 30 receives the information of the application A whose activation has been requested from the activation instruction unit 302.
- the activation possibility determination unit 104 determines whether the application A can be activated by the application execution unit 103 at the time of reception, in consideration of this information and a predetermined determination criterion (step S402). Here, if it is determined that the application can be started (step S403, Yes), the application execution unit 103 is notified of the start-up possibility by the start-up determination unit 104, and the electronic device 12 starts the application A. And executed (step S407). On the other hand, if it is determined that the activation is not possible (No in step S403), the activation deciding unit 104 notifies the application activation arbiter 30 of a response indicating that the activation is not possible.
- the startable The device search unit 303 searches the other electronic devices 13-1N for an alternative electronic device capable of starting the application A (step S404). As a result of the search, if there is an alternative electronic device (Step S405, Yes), the activation instruction unit 302 of the application activation arbitrator 30 instructs the alternative electronic device to activate the application A (Step S406). Then, the substitute electronic device that has received the instruction from the application activation arbitration device 30 receives the information of the application A whose activation has been requested from the activation instruction unit 302, and performs the processing from step S402 onward in the same manner as the electronic device 12.

- the activation permission / non-permission determination unit 104 determines whether or not its own electronic device has the ability to acquire the application A (step S601). Means that files can be exchanged and downloaded via. Whether file exchange or download is possible can be determined by checking file exchange restrictions and application distribution locations. The distribution location of the application can also obtain the attribute data of the application, for example. For example, in the case of the JAVA (registered trademark) execution environment, the attribute file data of the application is recorded in a JAD file distributed with the application.
- the distribution location of the file is described by a network address such as a URL or IP address, and if this network address is accessible, the application can be obtained by downloading. Can be determined. Of course, if you already have Application A, you have the ability to get it.
- the activation possibility determination unit 104 determines whether or not the application execution unit 103 1S has the capability to operate a plurality of applications simultaneously (Ste S602).
- the activation possibility determination unit 104 further determines whether the application execution unit 103 is executing another application (step S603). This determination is made because, depending on the operating environment of the application execution unit 103, it may not be possible to operate two or more applications at the same time. For example, KVM, which is a specification of the JAVA virtual machine, can run only one application. Therefore, the activation possibility determination unit 104 can determine the presence or absence of the simultaneous operation capability by inspecting the operation environment of the application execution unit 103.
- the start-up / non-execution determining unit 104 determines that the application executing unit 103 has requested the application A Then, it is determined whether or not the power has the specifications necessary for the operation (step S604). This specification determines whether or not it has the specifications and libraries that are prerequisites for operating application A. This determination can be made, for example, by comparing the attribute data of the application with the profile data of the application execution unit 103.
- the format of the attribute data of the application and the profile data of the application execution unit 103 depends on the method of realizing the application execution environment, the method of connecting the devices, and the communication protocol. For this reason, it cannot be determined uniquely, and several combinations are possible.
- the attribute file data of the application is recorded in a JAD file distributed with the application.
- the profile data of the application execution unit 103 data described in XML format is prepared for each application execution unit 103.
- the application attribute data such as JAD files must also analyze the necessary conditions for application execution, and the profile data of the application execution unit 103 such as XML data must also check whether the application execution unit 103 satisfies the conditions. Accordingly, the activation permission / non-permission determination unit 104 can determine whether the application can be activated.
- the activation possibility determination unit 104 determines that the application execution unit 103 has an available resource amount required for the operation of the requested application A. It is determined whether or not (step S605).
- the amount of resources required to execute an application may or may not be described in application attribute data such as the JAD file described above. If not, estimate the resources required before running the application.
- There are various methods for calculating the estimation but as an easy method, for example, a threshold (memory size 1 MB or the like) necessary for executing the application is set in advance, and the resource amount exceeding the value is set by the application execution unit 103. If it can be secured, a method such as deeming that the application can be executed is possible.
- Step S606 If it is determined that there is a free resource amount, the activation possibility determination unit 104 determines that application A can be activated (step S606). On the other hand, if any one of Steps S601, S603 and S605 is not satisfied, the activation possibility determination unit 104 determines that the activation of the application A is impossible (Step S607). Note that the order of each determination step is not limited to the order shown in FIG.
- This start possibility determination operation is the same as FIG. 6 up to step S601 and step S603. If it is determined that another application is currently running even if it has or does not have the simultaneous operation capability,! /, Na! / Referring to the history data recorded in 105, based on the past record of execution of the same application and the amount of resources used at that time, it is determined whether or not the requested application A can be started as follows. To judge.
- FIG. 8 is a view for explaining a specific example of history data recorded in the application execution history recording unit 105.
- the application execution history recording unit 105 records identification information for each application as history data. It also records the amount of resources used during execution. This resource amount information is not indispensable, but if it is prepared, it is possible to determine whether the application can be started more easily and with high accuracy.
- the content of the identification information can be considered as the type of application, file name, version information, creator, file size, etc. If it can uniquely identify the application, contents other than those shown in Fig. 8 can be used. Good.
- These pieces of history data are recorded in the application execution history recording unit 105 each time the application is executed by the application execution unit 103.
- the activation possibility determination unit 104 refers to the history data recorded in the application execution history recording unit 105. Then, it is determined whether the same application has been operated in the past (step S701). Specifically, it is determined whether or not an application having identification information that matches the identification information of application A requested to be started exists in the history data. As a result of this determination, when there is an application having the matching identification information, the activation possibility determination unit 104 determines the amount of free resources equal to or larger than the resource amount recorded in the history data of the application, by the application execution unit. It is determined whether or not the force 103 has. Then, when it is determined that the application A has the free resource amount, the activation possibility determination unit 104 determines that the application A can be activated (step S606). On the other hand, as a result of the determination in step S701, if there is no application having the matching identification information, the activation possibility determination unit 104 performs the processing in steps S604 and S605 shown in FIG.
- the bootable device search operation in step S404 is performed when an electronic device capable of starting an application in the current state is selected. (FIGS. 9 and 10) and a case where an electronic device capable of starting the application is selected while considering that the application currently being executed using the priority information and terminating the application is selected (FIGS. 11 and 12). ).
- the startable device search unit 303 analyzes the device information obtained in advance and analyzes the remaining electronic device 13- It is determined whether or not there is an electronic device capable of substituting the application A in 1N (step S901). As a result of the judgment, the electronic device that can If there is no such device (No at Step S902), it is determined that there is no alternative electronic device that can start the application A, and the process is terminated (Step S906). On the other hand, if there is only one electronic device that can be started (step S903, No), the electronic device is selected as a substitute electronic device (step S905).
- step S903 If there are two or more bootable electronic devices (step S903, Yes), one of the electronic devices is selected as a substitute electronic device based on predetermined conditions (step S904).
- the predetermined condition is that the free resource amount of the application execution unit 103 is the largest, that the specifications of the electronic device are suitable for the operation of the application, and the like.
- the bootable device search unit 303 selects an alternative electronic device using device information acquired in advance has been described.
- the startable device search unit 303 transmits the information of the application A to the remaining electronic devices 13-1N.
- the activation request including the request may be sent again (broadcast or broadcast)!
- the electronic device 13-1N that has received the activation request returns the result of the determination as to whether the application A can be activated and the current device information to the activation-capable device search unit 303 (FIG. 10). Further, the determination result of whether or not the application A can be started and the current device information may be obtained by separate communication.
- This startable device search operation is effective when it is determined that there is no alternative electronic device that can start application A as in step S906 in FIG. 9 described above.
- the startable device search unit 303 sends a request to the electronic device 13-1N when notified of a response indicating that the application A cannot be started, when the start determination unit 104 of the electronic device 12 is notified.
- the power also acquires the priority information (step S1101). This acquisition is performed by the application execution priority detection unit 304.
- FIG. 12 is a diagram showing a processing sequence regarding priority acquisition.
- the priority information indicates at least the following information.
- Information on the ability to acquire an application that realizes a service by downloading or exchanging files (2) Information as to whether or not the application execution unit has a specification capable of starting and operating the requested application. That is, information on whether or not the application has a specification, a library group, etc., as a premise for operating the application.
- the bootable device search unit 303 executes the processing of steps S901-S905 as described above. If it is determined that there is no alternative electronic device that can start the application A by these processes, the startable device searching unit 303 and the abrasion execution priority detecting unit 304 refer to the priority information and Is performed.
- an electronic device that does not have specifications that enable the application execution unit 103 to start and operate the application A is also excluded from the selection target power (step S1102).
- the electronic device in which another application is not operating is excluded from the selection targets remaining in step S1102 (step S1103). This is because an electronic device that is determined to be unstartable by the start-up / non-execution determining unit 104 even though another application is not running can be regarded as not having the ability to start the application. Furthermore, even if another running application is terminated, the application execution unit 103 cannot secure enough free resources to execute the application A. ⁇ The electronic device is excluded from the remaining selection targets in step S1103. (Step S1104).

- step S402 includes inquiring the user, that is, stopping the execution of the current application without negotiating the start (FIG. 13), and executing the current application after negotiating the start. (Fig. 14 and Fig. 16).
- the activation instruction unit 302 of the application activation arbitration device 30 instructs the alternative electronic device to activate the application A.
- the application execution unit 103 determines whether or not the current application is operating (step S1301). If it is in operation, the substitute electronic device determines whether or not the application execution unit 103 has a free resource amount capable of executing the application A (step S1302). If the result of this determination is that there is no free resource amount, the substitute electronic device stops the running application (step S1303).
- the alternative electronic device checks whether the application A is stored in the application storage unit 102 and must store the application A. For example, the application A is acquired by downloading or exchanging files (steps S1304 and S1305). After acquiring the application A, the application A is activated and executed by the alternative electronic device through the processing of steps S402 and S403 in FIG. 4 (step S407).
- the activation instruction unit 302 of the application activation arbitration device 30 instructs the alternative electronic device to activate the application A.
- the substitute electronic device inquires of the user whether to start application A (step S1401). This inquiry is made, for example, by displaying the dialog of FIG. 15 on the screen of the substitute electronic device. If the user's permission (for example, an explicit “Yes” input) is obtained in response to this inquiry, The processing of the 13 steps S1301 and S1302 is executed (step S1402, Yes).
- step S 1302 determines whether or not the currently running application can be stopped.
- This inquiry is performed, for example, by displaying the dialog of FIG. 16 on the screen of the substitute electronic device.
- the processing power of step S1303—S1305 in FIG. 13 described above is executed (step S1303). 1404, Yes).
- step S1405 if the user's permission is not obtained as a response to the question (including a case where a certain period of time during which the explicit input of ", ⁇ "has not passed), the application A is started. It is determined that the operation has failed, and the process ends (step S1405).
- the application start arbitration method of FIG. 4 described above is an operation of searching for an alternative electronic device when the electronic device 12 requested to start cannot start the application A.
- the application start arbitration method in FIG. 17 is an operation of waiting for the electronic device 12 whose start is requested to be able to start the application A without searching for an alternative electronic device.
- application activation arbitration device 30 that has received the activation request from electronic device 11 instructs electronic device 12 to activate application A by activation instruction section 302 (step S401).
- the electronic device 12 that has received the instruction from the application activation arbitration device 30 receives the information of the application A whose activation has been requested from the activation instruction unit 302. In consideration of this information and a predetermined determination criterion, the activation possibility determination unit 104 determines whether the application A can be activated by the application execution unit 103 at the time of reception (Step S402).
- Step S403 if it is determined that the application can be started (Step S403, Yes), the application execution unit 103 is notified of the start-up possibility by the start-up availability determination unit 104, and the electronic device 12 starts and executes the application A. Is performed (step S407). On the other hand, if it is determined that the activation is not possible (step S403, No), the activation permission determining unit 104 notifies the application activation arbiter 30 of a response that the activation is not possible. [0066] Upon receiving the notification that the activation is not possible from the activation possibility determination unit 104, the application activation arbitration device 30 starts monitoring the operation of the application execution unit 103 of the electronic device 12 by the delayed activation monitoring unit 307 (step S1701). .
- the application executability determination unit 104 periodically determines whether or not the application A can be activated (step S1702). Step S403). This periodic judgment can be realized by polling with a fixed period timer. If it is determined that the application can be started, the start-up / non-execution determination unit 104 notifies the application execution unit 103 of the start-up possibility, and the electronic device 12 starts and executes the application A (step S407). ). Being able to start application A during the monitoring period means that another application that was running on the electronic device 12 has been terminated and a state change has occurred, such as the availability of free resources. I do. On the other hand, if the monitoring is not possible even after the elapse of the monitoring period by the delayed activation monitoring unit 307, the application activation arbitration device 30 gives up activation of the application A and ends the activation arbitration process.
- the monitoring period of the delayed activation monitoring unit 307 may be infinite.
- the monitoring period of the delayed activation monitoring unit 307 may be stopped by a command to which user power is also given. If it is determined that the application A can be started, the user may be asked to start the application A. This inquiry is performed, for example, by displaying the dialog of FIG. 18 on the screen of the electronic device 12. If the user's permission (for example, an explicit input of "Yes") is obtained as a response to this inquiry, the process of step S407 is executed.
- the application start arbitration method of FIG. 17 may be performed instead of the application start arbitration method of FIG. 4, or may be performed in parallel. In the latter case, the ability to select an alternative electronic device by the application start-up arbitration method in Fig. 4 and whether the free resource amount of the target electronic device is secured by the application start-up arbitration method in Fig. 17 The application A is started in the electronic device.
- the application start arbitration system and method when the start of the application is impossible for the electronic device requested to start, the application start Ability to select another electronic device that can replace Waits until the requested electronic device is ready to start the application. As a result, a desired application can be started more reliably than before. Substitute electronic devices can be given flexibility in selecting electronic devices, taking into account the capabilities and priorities of each electronic device.
- Each functional block is typically implemented as an integrated circuit LSI (referred to as IC, system LSI, super LSI, ultra LSI, etc. depending on the degree of integration) (see the broken line in Fig. 1). ). These may be individually separated by one chip V, or may be separated by one chip to include a part or all of them.
- the method of circuit integration may be realized by a dedicated circuit or a general-purpose processor which is not limited to the LSI.
- a general-purpose processor which is not limited to the LSI.
- an FPGA Field Programmable Gate Array
- a reconfigurable processor that can reconfigure the connection and setting of circuit cells inside the LSI may be used.
- the present invention can be used in a system environment or the like in which a plurality of electronic devices are connected via a network, and is particularly useful when arbitrating the start of an application executed on the electronic device.
