Description

  The present invention relates to a technique for controlling a bundle in the OSGi technique.

  Currently, OSGi (Open Service Gateway Initiative) exists as one of middleware technologies for realizing modularization of software. In OSGi, it is possible to easily add new services, customize for each user, handle bugs, etc. by distributing and downloading software modules called bundles from the center system to each OSGi device. .

  Examples of OSGi devices include service gateways, routers, AV devices, automobiles, mobile phones, PDAs, PCs, network devices, and the like, and an OSGi framework that is an execution environment for executing bundles is implemented. Bundles distributed from the center system implement unique functions (for example, communication functions and e-mail functions for mobile phones) and other service functions for each OSGi device, and are activated and executed on the OSGi framework. Will be.

  Here, in Patent Document 1, a bundle (program operation state list) installed in an SGW (corresponding to the OSGi device) is managed by a management system (corresponding to the center system) (program ideal operation state). As a method for confirming whether or not the list matches, a technique for transmitting a program operation state list to the management system and comparing the two operation state lists on the management system side is disclosed.

  The management database unit 30 has a function of storing a management list in which a terminal ID for identifying the OSGi terminal 5 and a user ID of a user using the OSGi terminal 5 are linked. In addition, it has a function of storing a list of bundles (ideal state bundle list) associated with the contract information with which the user has contracted. This ideal state bundle list is generated in advance based on the contract information, and the ideal state bundle list includes bundle information of bundles that must be operated on the OSGi terminal 5 in order to provide a service contracted by the user. Are described in association with each contracted user ID. In the bundle information in the first embodiment, as shown in FIG. 2, a bundle symbolic name (Budle Symbolic Name), a bundle version (Bundle Version), and a URL from which a bundle can be acquired are described in association with each other.

  The bundle is a software module in the OSGi technology, and a plurality of bundles are combined and executed (download → installation → execution) on the OSGi framework implemented in the OSGi terminal 5, whereby the OSGi terminal 5, a predetermined service can be provided.

  The terminal ID receiving unit 31 has a function of receiving a terminal ID transmitted (sent) from the OSGi terminal 5 via the communication network 1.

  The user ID acquisition unit 32 has a function of reading a management list from the management database unit 30 and searching for and acquiring a user ID associated with the terminal ID of the OSGi terminal 5 received by the terminal ID reception unit 31. .

  The ideal state bundle list acquisition unit 33 has a function of receiving the user ID acquired by the user ID acquisition unit 32 and searching for and acquiring the ideal state bundle list corresponding to the received user ID from the management database unit 30. .

  The ideal state bundle list transmission unit 34 has a function of transmitting (returning) the ideal state bundle list acquired by the ideal state bundle list acquisition unit 33 to the OSGi terminal 5.

  Next, functions of the OSGi terminal 5 will be described. The OSGi terminal 5 includes a terminal ID acquisition unit 50, a terminal ID transmission unit 51, an ideal state bundle list reception unit 52, an operating bundle list acquisition unit 53, and a bundle control unit 54.

  The terminal ID acquisition unit 50 has a function of reading and acquiring a terminal ID for identifying the OSGi terminal 5 from a storage unit (not shown).

  The terminal ID transmission unit 51 has a function of transmitting (sending) the terminal ID acquired by the terminal ID acquisition unit 50 to the management system 3.

  The ideal state bundle list receiving unit 52 has a function of receiving the ideal state bundle list transmitted (returned) from the management system 3 via the communication network 1.

  The active bundle list acquisition unit 53 has a function of acquiring a list of bundles installed on the OSGi framework (active bundle list).

  The bundle control unit 54 compares the received ideal state bundle list with the acquired operating bundle list and controls the bundle based on the comparison result (bundle installation, uninstallation, activation, stop, update, etc. ) Function.

  The OSGi terminal 5 includes hardware such as a CPU and an OS (Operating System), and an OSGi framework that is a bundle execution environment is mounted on a Java (registered trademark) virtual machine. Then, each bundle is controlled (start, stop, inter-bundle service, security control, event processing, etc.) on the OSGi framework, whereby a predetermined service is provided to the user. Examples of such OSGi terminals 5 include service gateways, routers, AV devices, automobiles, mobile phones, PDAs, PCs, and network devices.

  Subsequently, a processing flow of the bundle control system according to the first embodiment will be described. FIG. 3 is a diagram illustrating a processing flow of the bundle control system according to the first embodiment.

  First, in the OSGi terminal 5, the terminal ID acquisition unit 50 acquires the terminal ID from the storage unit (not shown in FIG. 1) (Sa1), and the terminal ID transmission unit 51 uses the acquired terminal ID as a management system. Send (Sa2).

  Next, in the management system 3, the terminal ID reception unit 31 receives the terminal ID sent from the OSGi terminal 5 (Sa3), and the user ID acquisition unit 32 stores the user ID corresponding to the received terminal ID in the management database. It searches and acquires from the management list memorize | stored in the part 30 (Sa4).

  Then, the ideal state bundle list acquisition unit 33 searches and acquires the ideal state bundle list corresponding to the acquired user ID from the management database unit 30 (Sa5), and the ideal state bundle list transmission unit 34 acquires the ideal. The status bundle list is returned to the OSGi terminal 5 (Sa6).

  Thereafter, in the OSGi terminal 5, the ideal state bundle list receiving unit 52 receives the ideal state bundle list returned from the management system 3 (Sa7).

  On the other hand, the operating bundle list acquisition unit 53 acquires the operating bundle list installed on the OSGi framework (Sa8).

  Thereafter, the bundle control unit 54 compares the ideal state bundle list and the operating bundle list, and controls the bundle based on the comparison result (Sa9).

  As a method for the OSGi terminal 5 to send the terminal ID to the management system 3 and for the management system 3 to return the ideal state bundle list, for example, the management system 3 uses HTTP or HTTPS protocol, and the terminal ID is HTTP POST or the like. And returning the ideal state bundle list as its return value can be used.

  According to the first embodiment, since the OSGi terminal 5 implements the comparison process between the ideal state bundle list and the operating bundle list and the bundle control based on the comparison result, the OSGi terminal 5 is increased. Also, it becomes possible to prevent an increase in load in the management system 3. That is, in the prior art, the management system 3 needs to compare the ideal state bundle list and the operating bundle list and generate a program operation state change instruction according to the comparison result. Since no processing is required and only the search processing for the database is the main processing, the processing load on the management system 3 can be reduced.

  Subsequently, two specific control processing examples (control processing example 1 and control processing example 2) of the bundle control unit 54 in the OSGi terminal 5 having the above-described configuration and processing flow will be described.

[Control processing example 1]
The ideal state bundle list includes bundle information related to the bundle that should be operating on the OSGi terminal (however, it can be updated by a new contract or cancellation by the user, a bundle change based on the bundle information, etc.), As shown in FIG. 2, the bundle symbolic name, the bundle version, and the URL are included.

  On the other hand, the operating bundle list includes bundle information of bundles installed on the OSGi framework of the OSGi terminal 5, and the bundle information is described in association with the bundle symbolic name and the bundle version. (Included).

  Therefore, the bundle control unit 54 performs the following control as shown in FIG. 4 so that only bundles of bundle information described in the ideal state bundle list are activated. In addition, the format of each bundle list shown in FIG. 4 is an example, and is not limited to this. In general, comma delimiters, XML documents, and the like can be used.

  First, the processes of Sb1-1 to Sb1-3 are performed in random order (Sb1). Depending on the contents of the bundle information included in the ideal state bundle list or the in-operation bundle list, not all the processes of Sb1-1 to Sb1-3, for example, only Sb1-1, Sb1-1 and Sb1- One or more of the processes of Sb1-1 to Sb1-3, such as only 2, are performed.

  First, among bundle information included in the ideal state bundle list, installation processing / update processing is performed for bundle information in which bundle information having the same bundle symbolic name and bundle version is included in the operating bundle list. -Uninstall processing is not performed (Sb1-1).

  On the other hand, among bundle information included in the ideal state bundle list, bundle information whose bundle symbolic name and bundle version are the same is not included in the operating bundle list. The bundle is installed from the URL specified in the bundle information (Sb1-2).

  On the other hand, among bundle information included in the operating bundle list, bundle information whose bundle symbolic name and bundle version are the same is not included in the ideal state bundle list. Is uninstalled (Sb1-3).

  Thereafter, the package of the installed bundle is refreshed (Sb2). For example, the package can be refreshed by using the API of the PackageAdmin service defined in the OSGi specification.

  Finally, all bundles that are bundled in the ideal state bundle list and that are not activated among bundles installed on the OSGi framework are activated (Sb3).

  As described above, the processes of Sb1-1 to Sb1-3 are in no particular order, but the processes of Sb1 to Sb3 need to be performed in the above order (Sb1 → Sb2 → Sb3). In OSGi, for example, when bundle B needs to import a package exported by a certain bundle A, bundle B may set the bundle state to RESOLVED if bundle A is installed and the corresponding package is not exported. I can't start. For example, when the bundle of bundle symbolic name 2 in FIG. 4 needs to import a package exported by bundle symbolic name 1, the latter bundle is installed before the former, and the former bundle is not installed. If you try to activate the latter bundle, you cannot activate the latter bundle. Therefore, the bundle activation process of Sb3 needs to be performed after all the processes of Sb1 are completed.

  In addition, if the bundle with bundle symbolic name 1 imports the package that was exported by the old version of the bundle with bundle symbolic name 3 that was uninstalled, the bundle with bundle symbolic name 1 is unloaded unless the package is refreshed. The package that was exported by the old version of the bundle with the bundle symbolic name 3 installed will continue to be used (this is based on the OSGi specification). Therefore, a process for refreshing the package is required before the bundle activation process of Sb3.

  Therefore, it is necessary to perform processing in the order of Sb1 → Sc2 → Sb3.

[Control processing example 2]
Subsequently, a control processing example 2 different from the control processing method described in the control processing example 1 will be described. Even in the case of the control processing example 2, as in the case of the control processing example 1, the bundle control unit 54 is in a state in which only the bundle of bundle information described in the ideal state bundle list is activated at the end of the series of processing. As shown in FIG. 5, the following control is performed.

  First, the processes of Sc1-1 to Sc1-4 are performed in random order (Sc1). Depending on the contents of the bundle information included in the ideal state bundle list or the in-operation bundle list, not all of the processes of Sc1-1 to Sc1-4, for example, only Sc1-1, Sc1-1 and Sc1- Only one of the processes of Sc1-1 to Sc1-4, such as only 2, Sc1-1 to Sc1-3, or the like is performed.

  First, among bundle information included in the ideal state bundle list, installation processing / update processing is performed for bundle information in which bundle information having the same bundle symbolic name and bundle version is included in the operating bundle list. -The uninstallation process is not performed (Sc1-1).

  On the other hand, among bundle information described in the ideal state bundle list, bundle information that does not include bundle information with the same bundle symbolic name in the operating bundle list is included in the bundle information of the ideal state bundle list. The bundle is installed from the URL specified in (Sc1-2).

  On the other hand, for bundle information that is not included in the ideal state bundle list among bundle information that is listed in the active bundle list and that has the same bundle symbolic name, uninstall that bundle information bundle. (Sc1-3).

  On the other hand, among the bundle information described in the ideal state bundle list, the bundle information with the same bundle symbolic name and different bundle version is included in the active bundle list. After stopping the bundle of the bundle information in the list, a new bundle is downloaded and updated from the URL specified in the bundle information of the ideal state bundle list (Sc1-4).

  Thereafter, the package of the installed bundle is refreshed (Sc2).

  Finally, all bundles that are bundle information included in the ideal state bundle list and are installed on the OSGi framework are activated (Sc3).

  For the same reason as described in the control processing example 1, the processes of Sc1-1 to Sc1-4 are in no particular order, but the processes of Sc1 to Sc3 are performed in the above order (Sc1 → Sc2 → Sc3). It is necessary to do in.

  Regarding the bundle information corresponding to the process of Sc1-4 in the control process example 2, in the control process example 1, the old version bundle is uninstalled and the new version bundle is installed, but in the control process example 2, the bundle is updated. Will be. That is, according to the OSGi specification, in the case of the control processing example 1, the bundle ID of the corresponding bundle is changed, but in the case of the control processing example 2, there is a difference that the bundle ID is not changed. In addition, the bundle individual persistent storage returned by the BundleContext # getDataFile (String) method is not inherited between the old and new bundles in the control processing example 1, but is also inherited in the control processing example 2.

  Next, a bundle control system according to the second embodiment will be described. FIG. 6 is a diagram illustrating a functional block configuration of the bundle control system according to the second embodiment. The bundle control system according to the second embodiment is different only in the configuration of the OSGi terminal 5 according to the first embodiment, and further includes a URL generation unit 55.

  The URL generation unit 55 has a function of generating a URL from which a bundle can be acquired from the bundle symbolic name and the bundle version. On the other hand, the functions of each part of the management system 3 and the other parts of the OSGi terminal 5 are the same as those described in the first embodiment. However, the bundle information of the ideal state bundle list stored in the management database part 30 is included in the bundle information. As shown in FIG. 7, only the bundle symbolic name and the bundle version are described in association with each other, and there is no description about the URL necessary for obtaining the bundle.

  Therefore, when the URL needs to be installed or downloaded using the URL, the URL generation unit 55 (Sb1-2 in the control processing example 1 in the first embodiment, Sc1-2 or Sc1- in the control processing example 2). In the case of each processing of 4), a URL that can acquire a bundle from the bundle symbolic name and the bundle version is generated and returned to the bundle control unit 54. For example, a URL is generated by combining a predetermined character string, a bundle symbolic name, and a bundle version. As a specific example, the character string “http://www.acme.com/jar/” is determined in advance, the bundle symbolic name is “symbolicName”, and the bundle version is “1.0.0”. If there is, a URL "http://www.acme.com/jar/symbolicName_1.0.0.jar" is generated. It is not limited how the predetermined character string is given to the OSGi terminal 5.

  According to the second embodiment, since the URL is not included in the ideal state bundle list transmitted to the OSGi terminal 5, the amount of data transmitted via the communication network 1 is reduced, and the consumption network bandwidth and the management system side It is possible to reduce the load of the ideal state bundle list generation process and the parsing process on the OSGi terminal side.

  Next, a bundle control system according to the third embodiment will be described. According to the first embodiment and the second embodiment, based on the contract information registered in the management database unit 30 of the management system 3, a necessary bundle to be operated on each OSGi terminal 5 is distributed to the OSGi terminal 5, It can be activated. However, the management system 3 cannot grasp whether the bundle distribution has finally succeeded. Therefore, in the third embodiment, a system is provided in which the management system side can grasp the control result of the bundle performed by the OSGi terminal 5.

  FIG. 8 is a diagram illustrating a functional block configuration of the bundle control system according to the third embodiment. The bundle control system according to the third embodiment further includes a bundle control result report receiving unit 35 and a bundle control result report storage unit 36 in the management system 3 with respect to the bundle control system according to the second embodiment, and generates a bundle control result report. The OSGi terminal 5 further includes a unit 56 and a bundle control result report transmission unit 57.

  The bundle control result report generation unit 56 has a function of generating a bundle control result report in which a bundle is controlled by the bundle control unit 54 even if no bundle control is performed. The generated bundle control result report includes the terminal ID of the OSGi terminal 5 and information on the bundle that is operating on the OSGi terminal 5 (bundle current information).

  The bundle control result report transmission unit 57 has a function of transmitting the bundle control result report generated by the bundle control result report generation unit 56 to the management system 3.

  The bundle control result report receiving unit 35 has a function of receiving a bundle control result report transmitted from the OSGi terminal 5 via the communication network 1.

  The bundle control result report storage unit 36 has a function of registering the bundle control result report at the OSGi terminal 5 received by the bundle control result report receiving unit 35 in the management database unit 30.

  Subsequently, a processing flow of the bundle control system according to the third embodiment will be described. FIG. 9 is a diagram illustrating a processing flow of the bundle control system according to the third embodiment.

  First, processing similar to the processing of Sa1 to Sa8 described in the first embodiment is performed (Sd1), and in the OSGi terminal 5, the bundle control result report generation unit 56 performs bundle control based on the bundle control in the bundle control unit 54. A result report is generated (Sd2), and the bundle control result report transmission unit 57 transmits the generated bundle control result report to the management system 3 (Sd3).

  Thereafter, in the management system 3, the bundle control result report reception unit 35 receives the bundle control result report transmitted from the OSGi terminal 5 (Sd4), and the bundle control result report storage unit 36 receives the received bundle control result report ( The terminal ID of the OSGi terminal 5 and the bundle current information that is operating on the OSGi terminal 5 are registered in the management database unit 30 (Sd5).

  Here, it can be said that the communication network 1, the management system 3, and the OSGi terminal 5 are not always operating normally. For example, there is a possibility that the communication network 1 is disconnected when the OSGi terminal 5 tries to transmit a bundle control result report to the management system 3, or the management system 3 may be down.

  It is also possible to send a bundle control result report to the management system 3 only when some bundle control is performed in the processing in the bundle control unit 54. However, after the bundle control unit 54 finishes some bundle control, the bundle control result report is not registered in the management database unit 30 of the management system 3 due to the trouble as described above. Even if it is removed and normal operation is possible, the bundle control result report registered in the management database unit 30 of the management system 3 may be different from the actual situation of the OSGi terminal 5 forever. This is because even if a series of processes are performed again, the bundle control has already been successful in the OSGi terminal 5, and the acquired ideal state bundle list matches the operating bundle list, so no processing is performed. For this reason, the bundle control result report is not transmitted to the management system 3.

  Therefore, in the third embodiment, even when one bundle is not controlled by the bundle control unit 54 of the OSGi terminal 5, that is, when the ideal state bundle list matches the active bundle list. However, by sending the bundle control result report from the OSGi terminal 5 to the management system 3, it is possible to reliably grasp the bundle control result at the OSGi terminal 5 on the management system side. As a result, the final bundle state on the OSGi terminal is accumulated in the management database unit 30 of the management system 3 if at least a series of processes are performed again and there is no trouble such as communication failure or suspension of the management system 3. become. As described above, if the final bundle state is accumulated in the management database unit 30 of the management system 3, by separately searching the reported bundle current status information registered in the management database unit 30 using the terminal ID as a key, It becomes possible to grasp the final bundle state in the OSGi terminal 5. That is, in order to know the final bundle state in the OSGi terminal 5, it is not necessary to perform processing for performing bundle state acquisition control again on the OSGi terminal 5 from the management system 3 via the communication network 1, which is very useful. .

  Next, a bundle control system according to the fourth embodiment will be described. The functional block configuration of the bundle control system according to the third embodiment is the same as that of the third embodiment, but the functions of the ideal state bundle list acquisition unit 33 of the management system 3 and the bundle control result report generation unit 56 of the OSGi terminal 5 are the same. Is different.

  In the first to third embodiments, the ideal state bundle list acquisition unit 33 has only a function of searching and acquiring the ideal state bundle list corresponding to the user ID of the OSGi terminal 5 from the management database unit 30. In Example 4, the reported bundle current state information is searched and acquired from the management database unit 30 using the terminal ID received from the OSGi terminal 5 as a key, the ideal state bundle list is compared with the bundle current state information, and the comparison result is obtained. If there is a difference, it further has a function of including, in the ideal state bundle list, information on a report required flag indicating that a report from the OSGi terminal 5 is necessary.

  In addition, the bundle control result report generation unit 56 performs the bundle control when the bundle control unit 54 controls any bundle or when the ideal state bundle list received from the management system 3 includes a report required flag. Later, it further has a function of generating a bundle control result report.

  In the third embodiment, when the bundle control unit 54 of the OSGi terminal 5 matches the ideal state bundle list and the operating bundle list, one bundle has not been installed, updated, or uninstalled. Even so, the bundle control result report is transmitted from the OSGi terminal 5 to the management system 3, but is not transmitted in the fourth embodiment. As a result, the number of bundle control result reports transmitted to the management system 3 is reduced, registration processing in the management database unit 30 in the management system 3 is reduced, and the communication network consumption band can be reduced.

  On the other hand, in the case of the fourth embodiment, as compared with the case of the third embodiment, in the generation process of the ideal state bundle list, the process of reading the bundle current state information from the management database unit 30 and the comparison process of the ideal state bundle list It is conceivable that the communication network consumption band is increased by adding flag information to the ideal state bundle list. However, normally, the write process (the registration process) is heavier than the read process from the database, and the network in which the flag information increased in the ideal state bundle list transmitted from the management system 3 to the OSGi terminal 5 is consumed. Since the network bandwidth consumed by the bundle control result report transmitted from the OSGi terminal 5 to the management system 3 is larger than the bandwidth, the processing load of the management system 3 and the network consumption bandwidth are comprehensively increased in the fourth embodiment. Can be reduced.

  Finally, the management system 3 and the OSGi terminal 5 constituting the bundle control system according to the first to fourth embodiments can be configured by a computer having an arithmetic processing device such as a CPU and a storage device such as a memory. Yes, each function process is executed by a program. Such a program is stored in a storage device, and can be recorded on a recording medium or provided through a network.
