Abstract

<P>PROBLEM TO BE SOLVED: To restore program setting information after change in a service gateway. <P>SOLUTION: The SGW 1 decides whether or not start this time is the first start after initialization (S5), creates a start report including the initial start flag which shows decision results (S9) and transmits the start report (S11). A management system 2 judges whether or not the initial start flag is on (S210) and creates (S13) and transmits (S15) restoration instruction including backup setting information only when it is on. The SGW 1 overwrites the program setting information by the backup setting information in the instruction (S16). The SGW 1 changes the program setting information by operations (a change step). When the program setting information is changed by a restoration step or the change step, the SGW 1 generates a change report which shows the change content (S17) and transmits the change report (S19). The management system 2 updates the backup setting information by the change report (S21). <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a program setting information processing method and a program setting information processing system for processing program setting information for a program for remotely controlling a device from a service gateway connected to a management system via a communication network.

  In recent years, in order to provide a service for controlling a device (such as a home appliance) connected to a home network in a user's home, a device called a service gateway (hereinafter referred to as SGW) is arranged at the user's home and the SGW is placed on the SGW. A system for operating a program and controlling each device by the program has been developed. An environment for operating a program in the SGW is, for example, OSGi (Open Services Gateway initialive). OSGi dynamically installs / starts / stops / uninstalls / updates a program file stored in a management system such as a web server connected to the SGW or a program file held by the SGW as a program on the SGW. Provide a mechanism to do so.

  In order to run a program on the SGW in order to provide a service contracted by the user, various setting information (referred to as program setting information as a whole) is required. The program setting information is stored in a local file on the non-volatile SGW. When the SGW is restarted, the program setting information is generally read by each program, and each program operates according to the program setting information. Thereby, the same program setting information as the end of SGW can be used continuously. That is, it is possible to provide a continuous service across SGW stop / start.

  As a method for storing and reading out the program setting information, there is a method unique to each program, but it can also be realized by a common method. For example, in OSGi, a program provides a function of the OSGi service called Configuration Admin service determined by the specification, receives a request for saving, reading, and deleting setting information from another program, and stores it in a local file according to the request. Update or manage saved configuration information.

  The program setting information is not determined by the service contract of the user who uses the SGW, but the UI function for the user provided by the program operating on the SGW is the information received from the user by the Configuration Admin Depending on the service function, it may be set as program setting information.

Patent Document 1 discloses a method of storing program setting information of an application in a server and transmitting and setting it to a computer terminal when the application is used on the computer terminal. In this method, the change of the program setting information made while using the application is reported to the server when the application is terminated, and the program setting information of the server is changed accordingly, and it is sent to the computer terminal when the application is used next time. And set it.
JP 2004-86407 A

  The technique of Patent Document 1 uses program setting information at the end of an application next time, but it is not suitable for SGW in the following points. That is, the SGW may stop before the application ends due to an erroneous operation of a user who does not have specialized skills. For example, when the program setting information is changed in the SGW before the stop, the program setting information of the server, that is, the program setting information before the change is set (restored) in the SGW when the application is used next time.

  If the SGW is stopped, even if the program setting information is transmitted from the server to the SGW and set at the subsequent startup, the program setting information before the change is restored to the SGW.

  Also, some SGWs do not have a display device, and therefore there may be cases where the user cannot be notified that the program setting information before the change has been restored.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a program setting information processing method and a program setting information processing system capable of restoring program setting information after change in a service gateway. It is to provide.

  In order to solve the above-described problem, in the invention 1, when the service gateway is activated, it is determined whether or not it is the first activation after initialization. A startup report step that transmits a startup report including an initial startup flag set to OFF according to the judgment result, and a management system creates an instruction that includes backup setting information of program setting information when the initial startup flag in the startup report is ON An instruction step to send, a restoration step in which the service gateway overwrites the program setting information with the backup setting information in the command, a change step in which the service gateway changes the program setting information by an operation to itself, and the service gateway , Change report showing what happened during the restore or change step Because the change report step to be created and transmitted and the management system performs the backup step to make the backup setting information equal to the changed program setting information by the change report, the changed program setting information is restored at the service gateway. Can do. In addition, the program setting information after the change can be restored at an early timing when starting for the first time after initialization.

  In the invention 2, the change report including the program setting information after the change is created and transmitted in the change report step, and the backup setting information is overwritten with the program setting information included in the change report in the backup step. The difference period in which the difference is generated between the program setting information and the backup setting information can be shortened compared to the first aspect in which the difference is not resolved unless the backup setting information is updated when the setting information is changed.

  In the invention 3, the same change report number is set in the service gateway and the management system. In the change report step, the set change report number is updated, and a change report including the change report number is created and transmitted. The management system determines whether or not the update of the set change report number is equal to the change report number in the change report. If it is equal, the backup step is performed. Since the backup setting information is updated due to the creation and transmission of the command including the difference, the difference period is set as compared with the first aspect in which the difference is not resolved unless the backup setting information is updated when the same setting information is changed. Can be shortened.

  In the invention 4, the startup report including the initial startup flag and the program setting information is generated and transmitted in the startup report step, and the backup setting information is overwritten with the program setting information in the startup report in the backup step. In many cases, the difference period is shortened compared to the invention 3 in which the change of the setting information is rarely changed before the second activation. can do.

  In the invention 5, the management system associates the backup setting information of each generation with the generation number of each generation from the past to the present, and the management system determines the generation number indicating the generation and its generation for each past generation. The management system has a generation management information database that stores generation management information including the end time of the generation. The management system is set with the current generation number indicating the current generation, and the management system sets the initial startup flag in the startup report. If on, the first step is performed, and if the initial activation flag in the activation report is off, the second step is performed. In the first step, a command including backup setting information associated with a generation number equal to the current generation number , Create backup setting information equal to the backup setting information, store it, and increase the current generation number (for example, current generation 1 is added to the issue number (the same applies below), and the generation management information consisting of the generation number equal to the current generation number and the current time is added to the generation management information database, the current generation number is incremented, and the command In the second step, the backup setting information associated with the generation number equal to the current generation number is overwritten with the program setting information in the startup report, and the backup setting information equal to the overwritten backup setting information is created and stored. Since the current generation number is increased by associating the generation number with the increased current generation number, adding the generation management information consisting of the generation number equal to the current generation number and the current time to the generation management information database, the current generation number is increased. You can know the backup setting information.

  In the invention 6, the management system can set the designated generation number. In the first step, the presence / absence of the designated generation number is determined, and if it has the designated generation number, it is equal to the designated generation number. Create an instruction that includes the backup setting information associated with the generation number, create and store backup setting information that is equal to the backup setting information, associate the generation number that is increased with the current generation number, and set the generation number that is equal to the current generation number If the generation management information consisting of the current time is added to the generation management information database, the current generation number is incremented, the command is sent, and the specified generation number is not included, it is associated with the generation number equal to the current generation number Create an instruction that includes backup setting information, create and store backup setting information that is equal to the backup setting information, and increase the current generation number. A generation number is associated, and generation management information consisting of a generation number equal to the current generation number and the current time is added to the generation management information database, the current generation number is incremented, and an instruction is sent. The program setting information can be restored by the backup setting information.

  In the invention 7, the program setting information includes unit information including the setting information and the setting information ID indicating the setting information for one or more setting information. In the restoration step, the program setting information is predetermined as overwritten program setting information. Since the unit information including the set setting information ID is included, the management system can recognize whether or not there is a difference, so that it is possible to cope with the case where there is a difference. In the invention 8, the management system can set the designated generation number, and the program setting information includes unit information including the setting information and the setting information ID indicating the setting information for one or more setting information. In the restoration step, unit information including a predetermined setting information ID is included in the program setting information after overwriting, and in the first step, the presence or absence of the designated generation number is determined, and the designated generation number is provided. In this case, create an instruction including backup setting information associated with the generation number equal to the specified generation number, create and store backup setting information equal to the backup setting information, associate the generation number with the increased current generation number, Adds the generation management information consisting of the generation number equal to the generation number and the current time to the generation management information database, increases the current generation number, and If there is no specified generation number, a command including backup setting information associated with the latest generation number is created in the backup setting information including unit information including the predetermined setting information ID. Creates and stores backup setting information equal to the backup setting information, associates the generation number with the current generation number increased, and adds generation management information consisting of the generation number equal to the current generation number and the current time to the generation management information database However, since the current generation number is incremented and the command is transmitted, the program setting information can be restored even if there is no specified generation number, and the restoration is performed using the backup setting information associated with the latest generation number. Therefore, it is not necessary to change the program setting information after restoration.

  According to the present invention, the changed program setting information can be restored in the service gateway.

  Embodiments of a program setting information processing method and system according to the present invention will be described below with reference to the drawings.

  FIG. 1 shows an overall view of the embodiment.

  A device called a service gateway (hereinafter referred to as SGW) 1 disposed in each user's home is connected to a management system 2 that manages services via a communication network such as the Internet. The SGW 1 is connected to devices 3 (in the figure, HDD recorder, door lock) such as various home appliances and AV devices via various home networks. Hereinafter, processing in one SGW1 (simply referred to as SGW1) and the management system 2 will be described, but the same processing is performed in the other SGW1 and the management system 2.

  FIG. 2 shows functional blocks of SGW1.

  The SGW 1 includes a management system transmission / reception function unit 11, a program state control function unit 12, a program operation state collection function unit 13, and a program setting information management function unit 14.

  The management system transmission / reception function unit 11 has a function of transmitting / receiving information to / from the management system 2 and passing a program operation state change command received from the management system 2 to the program state control function unit 12. This program operation state change instruction includes an operation control instruction such as installation related to the program.

  The program state control function unit 12 has a function of executing each processing instruction in the program operation state change instruction delivered from the management system transmission / reception function unit 11. The program operation state collection function unit 13 has a function of collecting operation state information related to the installed program and passing it to the management system transmission / reception function unit 11. The management system transmission / reception function unit 11 has a function of transmitting an operation state change command execution report created based on the information to the management system 2.

  In addition, information called program setting information is set in advance in the SGW 1 so that the program setting information can be changed by operating the SGW 1. The changed program setting information is returned to the original program setting information upon initialization by an operation on the SGW 1.

  The program setting information management function unit 14 has a function of saving each setting information constituting the program setting information in the file system and collecting the saved setting information in response to a request from each program and the management system transmission / reception function unit 11. Have. In addition, when there is a change in the program setting information, the management system transmission / reception function unit 11 has a function of passing a change report indicating the change contents.

  FIG. 3 shows specific functional blocks of the SGW 1.

  In the SGW 1, a program execution environment providing unit 101 that provides a program execution environment and manages and controls the execution state of the SGW 1 controls the SGW operation management program 102 and the devices 3 such as various home appliances and AV devices. A program (HDD recorder control program, door lock control program in the figure) 103 operates. These device control programs 103 have a function of controlling the device 3 through communication via a network communication interface for home network (hereinafter, interface is abbreviated as IF) 104.

  The program execution environment providing unit 101 has a function of accepting a request to collect information on the operation state of a program installed on the execution environment from the SGW operation management program 102 and passing the collected information to the SGW operation management program 102. . Further, the program execution environment providing unit 101 uses the designated program file from the SGW operation management program 102 to request to install or update a program that operates on the program execution environment providing unit 101, and to install an installed program. It has a function of accepting requests to start, stop, uninstall, etc. and execute the requests. That is, it has a function of controlling the operating state of the program.

  Further, the SGW operation management program 102 has a function of communicating with the management system 2 via the network communication IF 104 and transmitting information to the management system 2.

  Further, the setting information management program 102A has the function of the program setting information management function unit 14.

  As an example of the program execution environment providing unit 101 of the SGW1, the OSGi framework can be considered. In this case, the SGW operation management program 102 and other programs are executed in units called bundles in terms of OSGi on the same process. However, the SGW operation management program 102 is a program designated for the OSGi framework. It is possible to install a new program with a file, update an installed program with a specified program file, stop a running program, start a stopped program, and uninstall from the OSGi framework . In OSGi, the function of the program setting information management function unit 14 can be realized by a bundle that provides the function of the Configuration Admin service.

  Here, as an example of the combination of the program execution environment providing unit 101, the SGW operation management program 102, and the setting information management program 102A, an OSGi framework and a bundle are given, but the present invention is not limited to this. That is, the management system transmission / reception function unit 11, the program state control function unit 12, the program operation state collection function unit 13, and the program setting information management function by the program execution environment providing unit 101, the SGW operation management program 102, and the setting information management program 102A. The unit 14 may be realized.

  FIG. 4 shows functional blocks of the management system 2.

  The management system 2 creates an operation information storage database 21 (hereinafter referred to as OP information DB 21) for storing various information related to the operation of the management system 2, and an ideal operation state for creating a program ideal operation state list that is a list of programs to be operated in the SGW 1 Derivation function unit 22, operation change command creation function unit 23 for creating an operation state change command execution report, network communication IF 24 with a communication network, distribution program file storage server 25 storing program files, program setting information and its A setting information processing function unit 26 for processing backup setting information is provided.

  In the management system 2, when information is transmitted from a certain SGW 1, SGW identification information indicating the SGW 1 (hereinafter, identification information is referred to as ID) can be obtained.

  For example, the management system 2 obtains the SGW ID included in the report by the SGW 1. In addition, the management system 2 obtains a line number such as a telephone line to which the SGW 1 is connected, and obtains an SGW ID associated with the line number. Further, the source IP address of the IP packet that constitutes the report or the like is obtained, and the SGWID associated with it in advance is obtained.

  Thereby, the information and database for the SGW 1 can be used to transmit information to the SGW 1. Note that description of information to be used and selection of a transmission destination will be omitted.

  Although not shown, the OP information DB 21 includes information for deriving an ideal operation state of each program in the SGW 1.

[Example 1]
FIG. 5A is a diagram illustrating program setting information included in the SGW 1. The program setting information includes unit information composed of setting information and a setting information ID indicating the setting information for each of one or more setting information read and used by a program installed in the SGW 1.

  FIG. 5B is a diagram showing backup setting information included in the management system 2. The backup setting information has the same configuration as the program setting information and is stored in the OP information DB 21.

  Although not shown, the OP information DB 21 includes similar backup setting information for the other SGW1, and each backup setting information is given an SGWID indicating the corresponding SGW1. By verifying this with the SGWID obtained by the management system 2, correct backup setting information is used.

  As shown in FIG. 6, after the SGW 1 is activated (S1) and the program execution environment providing unit 101 is automatically activated accordingly (S2), the SGW operation management program 102 is automatically activated (S3).

  As shown in FIGS. 6 and 7, the SGW 1 determines whether or not the current activation is the first activation after initialization (S5). At this time, an initial activation flag indicating the determination result is generated and stored.

  For example, when a certain empty storage area is not empty due to initialization, as shown in FIG. 8A, it is determined whether or not the storage area is empty (S5). By storing a file or the like in the storage area, the storage area is not emptied (S511), the initial activation flag is turned on (S512). On the other hand, if NO is determined in S5, the initial activation flag is turned off. (S513).

  For example, when a certain non-empty storage area is emptied by initialization, as shown in FIG. 8B, it is determined whether or not the storage area is empty (S5). The initial activation flag is turned off (S521). On the other hand, if NO is determined, the storage area is emptied (S522), and the initial activation flag is turned on (S523).

  Further, as shown in FIG. 6 and FIG. 7, information on the operation state of the program in the SGW 1 is collected, and a program operation state list, that is, a list of operation states of the programs installed in the SGW 1 is created using the collected information. (S7).

  Then, an activation report including an initial activation flag and a program operation state list is created (S9) and transmitted to the management system 2 (S11). S9 and S11 constitute an activation report step.

  The management system 2 uses the various information in the OP information DB 21 to derive the ideal operating state of each program in the SGW 1 and creates a program ideal operating state list indicating the operating state of each derived program. Then, the transmitted program operation state list of the activation report is compared with the program ideal operation state list, and the state of the program operation state list is the program ideal operation state after the program operation state change command to be described later is executed in the SGW1. A program operation state change command that makes a list state is created and sent to SGW1. Then, the SGW 1 executes this program operation state change command. As a result, SGW1 enters the state of the program ideal operation state list. If the comparison results match, no further processing is performed. A series of processing relating to the program may be omitted, and therefore will be omitted in the following description.

  As shown in FIG. 9, the management system 2 determines whether or not the initial activation flag is on (S210), and reads the backup setting information from the OP information DB 21 only when it is determined as YES. As shown in FIG. 9, a restoration command including the same is created (S13) and transmitted (S15). The restore command is a command for making the program setting information equal to the backup setting information in the restore command. Hereinafter, it is simply referred to as an instruction. S13 and S15 constitute an instruction step.

  As shown in FIG. 6, the SGW 1 overwrites the program setting information with the backup setting information in the command (S16: restoration step). This is performed before the execution of the program operation state change instruction transmitted together with the instruction.

  Moreover, SGW1 changes program setting information by operation to self (change step).

  When the program setting information is changed by the restoration step or the change step, the SGW 1 generates a change report indicating the change content (S17) and transmits it (S19). S17 and S19 constitute a change report step.

  The change report includes change information for each unit information that has been added, changed, or deleted. The change information about the added or changed unit information includes unit information after addition or change. The change information about the deleted unit information is composed of the setting information ID in the unit information.

  The management system 2 updates the backup setting information with the change report. That is, the backup setting information is made equal to the changed program setting information (S21: backup step).

  For change information of addition or change, unit information including the setting information ID in the change information is searched from the backup setting information, and if there is corresponding unit information, it is overwritten with the change information, otherwise Add the change information to the backup setting information as unit information. For deletion change information, unit information including the setting information ID in the change information is deleted from the backup setting information.

  As shown in FIG. 10, the unit information includes status information indicating whether it is valid or invalid. When the unit information is overwritten or added, the status information is valid, and when the unit information is deleted, The state information may be invalidated.

  Therefore, according to the first embodiment, the changed program setting information can be restored in the SGW 1. In addition, the program setting information after the change can be restored at an early timing when starting for the first time after initialization. Since the restoration is not performed at the second and subsequent activations after initialization, the changed program setting information can be used continuously. Further, since the backup step is triggered not by the end of the program but by the change of the program setting information, the probability that the backup setting information is the same as the latest program setting information can be increased.

[Example 2]
By the way, when each change information is transmitted sequentially, there is a possibility that the change information about the door lock setting information may not arrive due to communication circumstances or the like. In the first embodiment, there is a difference between the program setting information and the backup setting information in the period from when the door lock setting information is changed again until the change information arrives. That is, even if change information about other setting information arrives, the door lock unit information is still different, so the difference cannot be resolved. If initialization and activation are performed during that period, the program setting information before the change is restored, and the program setting information must be changed again.

  The second embodiment is intended to shorten the difference period, and differs from the first embodiment in the following points.

  That is, in S17 and S19, a change report including the changed program setting information is created and transmitted, and in S21, the backup setting information is overwritten with the program setting information in the change report. In overwriting, unit information not included in the program setting information is deleted from the backup setting information. Note that the status information of the unit information to be deleted may be invalidated.

  Therefore, according to the second embodiment, even if a change report is generated when any setting information is changed, as long as it arrives and the backup setting information is updated, the difference is resolved. The difference period can be shortened as compared with the first embodiment in which the difference is not resolved unless the backup setting information is updated when the information is changed.

[Example 3]
The third embodiment is also intended to shorten the difference period, and differs from the first embodiment in the following points.

  The same change report number is set in advance in the SGW and the management system. When the SGW 1 generates an initial activation flag after step S5, it determines whether or not the initial activation flag is on as shown in FIG. 11 (S110). If it is determined as YES, it is set to itself. The change report number is reset to a predetermined number (for example, 0) or a random number (S113). After that, or when NO is determined in step S110, the change report number set in itself or the reset change is reset. An activation report including a report number and an initial activation flag is created (S9a), and the process proceeds to S11.

  As shown in FIG. 12, when it is determined YES in step S210, the management system 2 performs S13 and then overwrites the change report number set in itself with the change report number in the activation report (S211). ), Go to S15. On the other hand, if it is determined as NO in step S210, the process ends.

  Further, as shown in FIG. 13, the SGW 1 when the program setting information is changed updates the change report number set in itself (S121), and creates a change report including the change report number and the initial activation flag. (S17a), the process proceeds to S19. The change report number is updated, for example, by incrementing the change report number by one.

  As shown in FIG. 14, the management system 2 when this change report is transmitted determines whether or not the change report number in the change report is equal to the change report number obtained by updating the change report number set in itself. Determine (S220). When it determines with YES, the change report number set to self is updated (S221), backup setting information is updated by a change report (S222), and it ends.

  On the other hand, when it is determined NO in step S220, a command including backup setting information is created (S223), transmitted to SGW1 (S224), and the process ends.

  As shown in FIG. 15, the SGW 1 when this command is transmitted updates the change report number set in itself (S130), and overwrites the program setting information with the backup setting information in the command (S131). A change report including the updated change report number and the overwritten program setting information is created (S132), transmitted to the management system 2 (S133), and the process ends.

  As shown in FIG. 16, the management system 2 when this change report is transmitted overwrites the change report number set in itself with the change report number in the change report (S230), and the program in the change report The backup setting information is overwritten with the setting information (S231), and the process ends.

  Therefore, according to the third embodiment, any change report generated with any change in the setting information is received, and as long as it reaches S231, the difference is resolved. The difference period can be shortened as compared with the first embodiment in which the difference is not resolved unless the backup setting information is updated when the information is changed.

  Moreover, since the size of the change report number in the change report transmitted in S19 of Example 3 is smaller than the program setting information in the change report transmitted in S19 of Example 2, in Example 3, Compared to the second embodiment, the size of the change report transmitted in S19 can be reduced.

  On the contrary, in the second embodiment, since the program setting information is included in the change report transmitted in S19, and the difference is thereby eliminated, the difference is eliminated by the subsequent change report transmitted in S133. The difference period can be shortened as compared with FIG.

[Example 4]
The fourth embodiment is also intended to shorten the different period, and differs from the first to third embodiments in the following points.

  As shown in FIG. 17, after step S113 or if NO is determined in step S110, an activation report including an initial activation flag, a change report number, and program setting information is created (S9b), and the process proceeds to S11.

  As shown in FIG. 18, the management system 2 that has transmitted this activation report overwrites the change report number set in itself with the change report number in the activation report (S251), and the initial activation flag in the activation report is set. It is determined whether or not it is on (S253). If YES is determined, an instruction including backup setting information is created (S255), transmitted (S257), and the process ends.

  On the other hand, when it is determined NO in S253, the backup setting information is overwritten with the program setting information in the activation report (S26), and the process ends.

  Therefore, according to the fourth embodiment, the difference is resolved at the second activation after the initialization. Since it is rare that the setting information, which is an opportunity for eliminating the difference in the third embodiment, is changed before the second activation, the difference period can be shortened in many cases as compared with the third embodiment.

[Example 5]
The fifth embodiment differs from the fourth embodiment in the following points.

  As shown in FIG. 19, in the management system 2, the backup setting information of the generation is associated with the generation number of each generation from the past to the present.

  Further, as shown in FIG. 20, the management system 2 includes a generation management information database 21A in which generation management information including a generation number indicating the generation and an end time of the generation is stored for each past generation. .

  In the management system 2, a current generation number indicating the current generation is set and is incremented by one.

  The other SGW 1 has the same configuration. The generation number, the backup setting information for each generation, the generation management information database 21A, and the current generation number are stored in the OP information DB 21, and a corresponding SGWID is assigned.

  As shown in FIG. 21, immediately before performing step S210, the management system 2 overwrites the change report number set in itself with the change report number in the activation report (S209). And when it determines with YES by S210, the following processes (it is called 1st step) are performed. In the first step, first, an instruction including backup setting information associated with a generation number equal to the current generation number is created (S13a). Then, backup setting information equal to the backup setting information is created and stored, and a generation number obtained by adding 1 to the current generation number is associated (S271). Then, generation management information including a generation number equal to the current generation number and the current time is added to the generation management information database 21A (S272), the current generation number is increased (S273), and when the first step is completed, S15 is completed. Move on.

  On the other hand, when it is determined NO in S210, the following process (referred to as a second step) is performed. In the second step, first, the backup setting information associated with the generation number equal to the current generation number is overwritten with the program setting information in the activation report (S26a). Then, backup setting information equal to the backup setting information after overwriting is created and stored, and the generation number obtained by adding 1 to the current generation number is associated (S274). Then, generation management information consisting of a generation number equal to the current generation number and the current time is added to the generation management information database 21A (S275), the current generation number is incremented (S276), and the process ends with the second step.

  Therefore, according to the fifth embodiment, it is possible to know backup setting information at a past time point.

  For example, when time T is specified, n satisfying (end time of (n-1 generation)) <T <(end time of n generation) is obtained, and backup setting information associated with the generation number of n generation, that is, The backup setting information at the time when the SGW 1 is stopped for the first time after the time T can be obtained. Further, the backup setting information associated with the generation number of the (n-1) generation that satisfies the above equation, that is, the backup setting information at the time when the SGW 1 was last stopped before time T can be obtained.

  The end time may be replaced with the start time. For example, as shown in FIG. 22, the current generation number is increased immediately after S209 (S277), and in S13a, an instruction including backup setting information associated with the generation number obtained by subtracting 1 from the current generation number is created. In S271, the backup setting information equal to the backup setting information is created and stored, and the generation number equal to the current generation number is associated. In S26a, the backup setting information associated with the generation number obtained by decrementing the current generation number by 1 is activated and reported. In S274, backup setting information equal to the overwritten backup setting information is created and stored, and a generation number equal to the current generation number is associated. In S272 and S275, 1 is assigned from the current generation number. The generation management information consisting of the reduced generation number and the current time is stored in the generation management information database 21. Add to, it may be omitted S273, S276.

  In this aspect, the backup setting information at the time when SGW 1 is stopped for the first time after time T obtains n satisfying (starting time of n generation) <T <(starting time of n + 1 generation), and sets the generation number of n generation. It can be obtained as associated backup setting information.

[Example 6]
Example 6 differs from Example 5 in the following points.

  The management system 2 can set a number called a designated generation number.

  As shown in FIG. 23, if YES is determined in S210, that is, in the first step, first, the presence / absence of the designated generation number is determined (S280). If YES is determined, the designated generation number is set. An instruction including backup setting information associated with the same generation number is created (S13b), and the process proceeds to S271. On the other hand, if NO is determined, an instruction including backup setting information associated with a generation number equal to the current generation number is created (S13a), and the process proceeds to S271.

  Therefore, according to the sixth embodiment, the program setting information can be restored with the backup setting information associated with the designated generation number.

  For example, when the user at the user's home where the SGW 1 is arranged designates the past time T to the operator by telephone or the like, n, n−1, etc. satisfying the formulas described in the fifth embodiment, etc., are obtained, which are designated generations. Set as a number. Then, the program setting information is restored when the user who has received the setting notification restarts the SGW 1.

  Further, when the user at the user's home where the SGW 1 is arranged designates a past time T on the web server, n, n−1, etc. satisfying the formulas described in the fifth embodiment, etc. are obtained, which are designated generation numbers. Is set. Then, the program setting information is restored when the user who has viewed the setting completion screen displayed by the web server restarts the SGW 1.

  Alternatively, the web server may display a list of times in the generation management information database 21A on the terminal screen, and the time selected by the user or operator may be used as the designated time.

  Also, the web server accepts a backup application from the user or operator, whereby the management system 2 sends a backup request command to the SGW 1, whereby the SGW 1 sends a backup request including the program setting information. Go to S13a of 21. In this way, backup may be performed.

[Example 7]
In Example 2, Example 3, and Example 4, the difference period was shortened. This also solves the inconvenience that the program setting information before the change is restored and the program setting information is forced to be changed again when initialization and activation are performed in the different period.

  On the other hand, by making it possible for the management system 2 to determine whether there is a difference, it is possible to cope with a case where there is a difference. Example 7 will be described as an example.

  The seventh embodiment is different from the first embodiment to the sixth embodiment in the following points.

  In the seventh embodiment, when the program setting information is changed by the restoration step, as shown in FIG. 24, unit information including a predetermined setting information ID is included in the changed program setting information (S140 ), Go to S17. It can be understood that the setting information ID is the ID. For example, if the normal setting information ID is 4 digits, the ID is made 5 digits.

  Therefore, according to the seventh embodiment, when the change information in the change report transmitted in S19 is sequentially transmitted, the change information including the predetermined setting information ID is transmitted last, thereby the change information. The backup setting information is provided with unit information equal to, and in this case, the difference is always eliminated. Therefore, the presence or absence of the difference can be determined based on the presence or absence of the predetermined setting information ID. For example, the use of backup setting information that does not have the predetermined setting information ID can be avoided.

[Example 8]
For example, Example 8 will be described as an example. The eighth embodiment differs from the seventh embodiment in the following points.

  As shown in FIG. 25, in S13a, an instruction including backup setting information associated with the latest generation number is created among backup setting information including unit information including a predetermined setting information ID.

  Therefore, according to the eighth embodiment, the program setting information can be restored even when there is no designated generation number, and the restoration is performed using the backup setting information associated with the latest generation number. It is not necessary to change the program setting information again.

  A computer program for realizing the SGW 1 and the management system 2 by a computer is stored in a computer-readable recording medium such as a semiconductor memory, a magnetic disk, an optical disk, a magneto-optical disk, or a magnetic tape, and is distributed for display. Alternatively, the computer program may be transmitted via a communication network such as the Internet.
