Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is applied to a home gateway, a PC, an STB (Set Top Box), a network card, a mobile phone, a PDA (Personal Digital Assistant), a wristwatch, and other devices capable of executing a program to reconfigure a bundle for providing a predetermined service. In particular, the present invention relates to a bundle reconfiguration system, a bundle reconfiguration program, and a bundle reconfiguration method suitable for improving the memory utilization efficiency in a home gateway in which a bundle is dynamically incorporated.
[0002]
[Prior art]
In the near future, it is expected that each home will connect a home gateway to the Internet, connect multiple network devices to the home gateway, and each network device will use services on the Internet via the home gateway. Is done.
[0003]
A wide variety of network devices are connected to the home gateway. For example, a network compatible scanner or printer. In addition, OA products, home appliances, and other electronic devices can be connected as network devices. In order for the home gateway to properly control the network device, it is necessary to incorporate a control program for the network device into the home gateway, but it is not realistic to incorporate a control program for all possible types of network devices. Absent. Therefore, in reality, a network device manufacturer or the like sells a network device, and at the same time, posts a control bundle, which is a control program, on a predetermined server so that it can be downloaded. When the network device purchased by the user is connected, the corresponding control bundle is downloaded from a predetermined server and executed in the home gateway. Downloading is performed automatically or manually by the user.
[0004]
However, as the number of network devices connected to the home gateway increases, it is necessary to incorporate a large number of control bundles accordingly. However, the memory capacity of the home gateway is sufficient because the control bundles are executed on the memory. If not, there is a certain limit to the number that can be included.
Therefore, it is required to devise so that more control bundles can be incorporated under the limited memory capacity. Conventionally, as a technique for improving the memory utilization efficiency and related techniques, for example, an object-oriented language execution processing method (referred to as a first conventional example) disclosed in Patent Document 1 is disclosed in Patent Document 2. And a software processing system (referred to as a second conventional example) and a data processing device disclosed in Patent Document 3 (referred to as a third conventional example).
[0005]
In the first conventional example, the class information storage device holds class information including a class name, a class attribute, method information, and a method definition so as to be searchable by class ID. Upon receiving the message, the object issues a query specifying the class ID and method selection information, and in response to this, the method search unit searches the class information storage device for a method that matches the class ID and method selection information. The object then executes this retrieved method. The class information extraction unit extracts class information when compiling the class definition source program and stores it in the class information storage device. The exclusive control unit performs exclusive control of access of the method search unit and the class information extraction unit to the class information storage device.
[0006]
In the second conventional example, all processing codes that call functions of a specific component are concentrated on a management component that manages the processing code. When dynamic extension is performed, information for component cooperation is automatically updated by exchanging management components together with specific components. Other components can be reused.
[0007]
In the third conventional example, an item identifier for identifying item data, the type of item data, and an attached program for executing item data associated with at least one of the item identifiers is read by the input unit and the item data is processed. And a program selection unit that selects either the internal program for each processing module stored in the program storage unit or the attached program according to the content of the item identifier.

[2. Operation of this embodiment]
Next, the operation of the above embodiment will be described.
First, a case where the home gateway 200 acquires the control bundle 400 corresponding to each device 210 to 220 will be described.
[0084]
In order to acquire the control bundle 400, the user requests acquisition of the control bundle 400 in the home gateway 200. In the home gateway 200, when acquisition of the control bundle 400 is requested, a bundle acquisition request is transmitted to the bundle management server 100 through steps S300 and S302.
When the bundle management server 100 receives the bundle acquisition request, the control bundle 400 related to the bundle acquisition request is generated through steps S200 to S204, and the generated control bundle 400 is transmitted to the home gateway 200.
[0085]
When the home gateway 200 receives the control bundle 400, the received control bundle 400 is stored in the RAM 54 through steps S304 to S310, and the control bundle 400 of the RAM 54 is executed. As a result, the corresponding devices 210 to 220 are appropriately controlled. For example, if the control bundle 400 corresponds to the device 210 that is a printer, the device 210 can obtain a good print result.
[0086]
In order to acquire the bundle reconfiguration bundle 402, the user requests acquisition of the bundle reconfiguration bundle 402 in the home gateway 200. In the home gateway 200, when acquisition of the bundle reconfiguration bundle 402 is requested, the bundle acquisition request is transmitted to the bundle management server 100 through steps S300 and S302.
[0087]
When the bundle management server 100 receives the bundle acquisition request, the bundle reconfiguration bundle 402 is generated through steps S200 to S204, and the generated bundle reconfiguration bundle 402 is transmitted to the home gateway 200.
In the home gateway 200, when the bundle reconfiguration bundle 402 is received, the received bundle reconfiguration bundle 402 is stored in the RAM 54 through steps S304 to S310, and the bundle reconfiguration bundle 402 in the RAM 54 is executed. Thereby, the bundle combination process and the bundle separation process are executed in a time division manner.
[0088]
Next, a case where a plurality of control bundles 400 are combined into one control bundle 400 will be described.
In the home gateway 200, when the bundle reconfiguration bundle 402 is acquired, bundle combination processing is executed. In the bundle combining process, when the memory usage rate of the RAM 54 becomes a predetermined value (for example, 80%) or more and the state continues for a predetermined period (for example, 3 hours), it can be combined from the RAM 54 through step S410. The control bundle 400 is searched. As a result, when the corresponding control bundle 400 is searched, the common package is identified by comparing the package included in the control bundle a and the package included in the control bundle b through steps S414 and S416. The packages other than the common package among the packages included in a, the packages other than the common package among the packages included in the control bundle b, and the common package are extracted from the control bundles a and b.
[0089]
Next, through steps S418 and S420, a component included in the control bundle a and a component included in the control bundle b are compared to identify a common component, and components other than the common component among the components included in the control bundle a are identified. Among the components included in the control bundle b, those other than the common components and the common components are extracted from the control bundles a and b.
[0090]
Next, through step S422, based on the component information 412 included in the control bundles a and b, the class included in the control bundle a and the class included in the control bundle b are compared and the common class is specified. At this time, if the class method included in the common class of the control bundle a and the class method included in the common class of the control bundle b completely match, the class included in the control bundle a is passed through steps S424 and S426. Are extracted from the control bundles a and b, and the classes included in the control bundle b are extracted from the control bundles a and b.
[0091]
Next, through step S428, a list of extracted packages, components, and classes (including class methods) is displayed. Here, when the user of the home gateway 200 specifies a functionally unnecessary package, component, class, and class method from the displayed list, the extracted package, component, and class are specified through step S432. Deleted items are deleted. The deleted packages, components, and classes are included in the combined control bundle 400 by describing identification information such as their names in a deleted item file or the like so that they can be separated after combining.
[0092]
Then, through steps S434 and S436, the control bundles a and b are reconfigured as one control bundle 400 based on the extracted packages, components, and classes, and the control bundles a and b are deleted from the RAM 54. .
If the class method included in the common class of the control bundle a does not completely match the class method included in the common class of the control bundle b, the class included in the common class of the control bundle a is passed through step S438. The method and the class method included in the common class of the control bundle b are compared to identify the common class method. Among the class methods included in the common class of the control bundle a, those other than the common class method, the control bundle b Among the class methods included in the common class, a class other than the common class method and a class including the common class method are configured as a new common class.

In the example of FIG. 15, the control bundle A is an ink remaining amount monitoring bundle that monitors the remaining ink amount of the device 210 that is a printer, and the remaining amount of ink in the device 210 is monitored by the control bundle A. The control bundle B is a remaining paper amount monitoring bundle for monitoring the remaining amount of paper in the device 210, and the remaining amount of paper in the device 210 is monitored by the control bundle B. In addition, the control bundles A and B include a printer status monitoring component that monitors the status of the device 210 in common.
[0094]
Therefore, when the memory usage rate of the RAM 54 is equal to or greater than a predetermined value and the state continues for a predetermined period, the control bundles A and B are searched as a control bundle that can be combined, and the printer status monitoring component is specified as a common component . The control bundles A and B are reconfigured as a control bundle C that eliminates duplication of printer status monitoring components. That is, the control bundle C includes components other than the printer status monitoring component among components included in the control bundle A, components other than the printer status monitoring component among components included in the control bundle B, and a printer status monitoring component. Yes. This combination can reduce the memory capacity of one printer status monitoring component.
[0095]
FIG. 16 is a diagram illustrating a second pattern for coupling the control bundle 400.
In the example of FIG. 15, the control bundles A and B are reconfigured as one control bundle C, but a control bundle D that can provide classes, components, and packages that the control bundle C has is generated. Furthermore, among the classes, components, and packages included in the control bundle D, the control bundle A ′ that refers to what is necessary to make the control bundle A function, and the control bundle among the classes, components, and packages included in the control bundle D A control bundle B ′ that references what is necessary to make B function is generated. In this case, the control bundles A ′ and B ′ include reference information that refers to them instead of classes, components, and packages. In this way, if the control bundle D is configured like a library, when other control bundles that use classes, components, and packages included in the control bundle D are applied, the control bundle D is similarly included in the control bundle D. Can be reconfigured as a control bundle that references the classes, components, and packages that are needed to make the control bundle work. Therefore, the memory capacity can be effectively reduced.
[0096]
FIG. 17 is a diagram illustrating a third pattern for coupling the control bundle 400.
In the example of FIG. 17, the control bundle A is configured to include classes and the like (referring to class methods, classes, components, or packages) 450, 452, and 454. The control bundle B is configured to have classes 450, 456, 458 and the like. Here, the same sign indicates a class having the same content.
[0097]
Therefore, when the memory usage rate of the RAM 54 becomes equal to or higher than a predetermined value and the state continues for a predetermined period, the control bundles A and B are searched as control bundles that can be combined, and the class 450 is a common class (common class, Common component or common package)). Further, when the user of the home gateway 200 designates the class etc. 452 for the control bundle A and the class etc. 456 for the control bundle B as the unnecessary class etc., the class etc. 452, 456 is deleted, and the control bundle A and B are reconfigured as a control bundle C having classes 450, 454, and 458.
[0098]
FIG. 18 is a diagram illustrating a fourth pattern for coupling the control bundle 400.
FIG. 18 shows an example in which the control bundles A and B are combined when the class method included in the common class of the control bundle A and the class method included in the common class of the control bundle B do not completely match. . In the example of FIG. 18, the control bundles A and B include a class Q as a common class, but the class Q of the control bundle A includes class methods X and Y, and the class Q of the control bundle B includes Class methods X and Z are included, respectively, and the class methods of the control bundles A and B do not completely match.
[0099]
Therefore, when the memory usage rate of the RAM 54 becomes equal to or higher than a predetermined value and the state continues for a predetermined period, the control bundles A and B are searched as a control bundle that can be combined, and the class Q is specified as a common class. At this time, since the class method included in the class Q of the control bundle A and the class method included in the class Q of the control bundle B do not completely match, the class method X is identified as a common class, and the class method X, A class having Y and Z is configured as a new common class Q. Then, the control bundles A and B are reconfigured as a control bundle C having a new common class Q. Thereby, the part which concerns on the function of the control bundle A among the control bundles C and the part which concerns on the function of the control bundle B among the control bundles C can operate | move without a malfunction.
[0100]
FIG. 19 is a diagram illustrating a fifth pattern for combining the control bundles 400.
FIG. 19 shows the control bundles A and B when the class methods included in the common class of the control bundle A and the class methods included in the common class of the control bundle B do not completely match, as in the example of FIG. Is different from the case of FIG. 18 in that unnecessary class methods are deleted at the time of combining. In the example of FIG. 18, the control bundles A and B include the class Q as a common class. However, the class methods X, Y, and α are included in the class Q of the control bundle B. Includes class methods X, Z, and β, respectively.
[0101]
Therefore, when the memory usage rate of the RAM 54 becomes equal to or higher than a predetermined value and the state continues for a predetermined period, the control bundles A and B are searched as a control bundle that can be combined, and the class Q is specified as a common class. At this time, since the class method included in the class Q of the control bundle A and the class method included in the class Q of the control bundle B do not completely match, the class method X is identified as a common class, and the class method X, A class having Y and Z is configured as a new common class Q. Further, when the class method Y is specified as an unnecessary class method for the control bundle A and the class method Z is specified as an unnecessary class method for the control bundle B by the user of the home gateway 200, the class methods Y and Z are deleted, and the control bundle is deleted. A and B are reconfigured as a control bundle C having class methods X, α, and β. As a result, both the part related to the function of the control bundle A in the control bundle C and the part related to the function of the control bundle B in the control bundle C can operate without problems, and unnecessary class methods X and Y are deleted. Therefore, the memory capacity can be effectively reduced.
[0102]
Next, a case where the combined control bundle 400 is separated into a plurality of control bundles 400 will be described.
In the home gateway 200, when the bundle reconfiguration bundle 402 is acquired, a bundle separation process is executed. In the bundle separation process, when the user of the home gateway 200 requests the separation of the control bundle 400, the control bundle 400 that can be separated is searched from the RAM 54 through step S502. As a result, when the corresponding control bundle 400 is retrieved, a common package is specified from the control bundle c through steps S506 and S508, and all packages including the common package are extracted from the control bundle c.
[0103]
Next, through steps S510 and S512, a common component is specified from the control bundle c, and all components including the common component are extracted from the control bundle c.
Next, through steps S514 and S516, a common class is specified from the control bundle c based on the component information 412 included in the control bundle c, and all classes including the common class are extracted from the control bundle c.
[0104]
Next, a list of extracted packages, components, and classes (including class methods) is displayed through step S518. Here, when the user of the home gateway 200 specifies a functionally unnecessary package, component, class, and class method from the displayed list, the specification is made among the extracted package, component, and class through step S522. Deleted items are deleted.
[0105]
Then, through steps S528 and S530, based on the extracted package, component, and class, the control bundle c is reconfigured as the control bundles a and b before being combined, and the control bundle c is deleted from the RAM 54.
If the packages, components, classes, and class methods necessary for reconfiguring the control bundles a and b are insufficient, the necessary packages, components, classes, and class methods are insufficient through steps S526 and S528. Is acquired from the bundle management server 100, and based on the extracted package, component and class, and the acquired package, component and class, the control bundle c is re-established as the control bundles a and b before combining.
