Description

  The present invention relates to a technical field for updating software, for example, in a system made redundant by an operation system apparatus and a standby system apparatus.

  In recent years, with the spread of the Internet, an IP phone provided using an IP (Internet_Protocol: hereinafter referred to as “IP”) technology is used as a telephone service. This IP phone is rapidly spreading as an alternative to a general subscriber phone for reasons such as low usage fees and convenience. For this reason, users who use IP telephones are required to have a reliable telephone service. In a company that provides a telephone service in response to this request, for example, a call processing control device that controls call processing (hereinafter, also referred to as “call processing control server” in this application) is made more reliable by providing a redundant configuration. Realize sex.

  More specifically, the call processing control device is made redundant by call processing control devices of an active system and a standby system. For example, when a failure occurs in the call processing control apparatus operating as the active system, the call processing is continued by switching to the call processing control apparatus operating as the standby system. Therefore, a synchronization process of a storage device (hereinafter also referred to as “memory”) that holds operation information such as call information during communication is executed between the two call processing control devices. Thus, the two call processing control devices can back up the information stored in the storage device of the call processing control device operating as the active system to the storage device of the call processing control device operating as the standby system.

  Here, as related technologies existing prior to the application of the present application, there are, for example, Patent Literature 1 and Patent Literature 2. More specifically, as an example, Patent Document 1 discloses a technique related to a redundant system.

  The redundant system disclosed in Patent Document 1 includes an operation system device and a standby system device connected to each other. Further, the active system device and the standby system device synchronize the synchronization data generated by the operation of the application incorporated in these devices. The redundant system determines whether the version of the application installed in the active system device is different from the version of the application installed in the standby system device. When it is determined that the version of the application incorporated in the standby system apparatus is new, the redundant system causes the new version of the application to operate as the old version of the application. Thereby, the redundant system disclosed in Patent Document 1 can reduce the load on the apparatus that occurs when synchronizing the synchronization data.

  Patent Document 2 discloses a technique related to a software file update method. The software file update method disclosed in Patent Document 2 performs not only updating of a software file by addition of a service but also updating of station data accompanying the update of the software file in an electronic exchange operating as an active system and a standby system. To do. Here, the station data is information including the configuration conditions of the station installed in the electronic exchange such as the type of communication line and the number of lines.

  For example, in a call processing system made redundant by an active device and a standby device, when a software is repaired due to a failure or a service being added or modified, temporarily until the repair work is completed. Offline processing is required for the standby system device. In other words, the call processing system cannot perform the modification of the software while operating both the active device and the standby device.

  In particular, the call processing control device is used for inter-system storage devices (hereinafter referred to as “inter-system synchronous memory”) synchronized between the active system device and the standby system device in order to continue call processing. Synchronous processing is performed. Therefore, when a change such as a modification of software related to the inter-system synchronous memory is applied to the call processing control device, for example, the change work is a large-scale application that applies a new software package that involves updating a software file. Limited during renewal work. That is, the software change related to the inter-system synchronization memory cannot be easily implemented.

  When applying the software package, for example, the administrator of the call processing control apparatus not only needs to prepare an update software package, but also applies the software package to the call processing control apparatus. In this case, sufficient verification is required. In addition, the application of the software package has a problem that the work for applying the software package becomes large. Furthermore, when the application method of the software package is complicated, or when the size of a file to be updated by application of the software package is large, the application time may be long.

  Further, Patent Document 1 and Patent Document 2 only describe that the software package is applied. Therefore, in Patent Document 1 and Patent Document 2, the work related to the verification and application processing of the software package is still large-scale. That is, in Patent Document 1 and Patent Document 2, an enormous number of work steps occurs. Or patent document 1 and patent document 2 require time to update a software file.

  The main object of the present invention is to provide a call processing control device or the like that can more efficiently apply software changes between different devices even when the devices are in operation.

  In order to achieve the above object, a call processing control apparatus according to the present invention is characterized by having the following configuration.

When applying the plug-in file, execute the system disconnection process,
After the plug-in file is applied, either the stop or restart of the inter-system synchronization process is executed and the incorporation process is executed.

  Alternatively, the object can be achieved by a call processing system including the call processing control device described above.

  In order to achieve the object, the software update method according to the present invention is characterized by having the following configuration.

That is, the software update method according to the present invention includes:

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

<First Embodiment>
FIG. 1 is a block diagram showing a configuration of a call processing system 10 including a first call processing control device 1 and a second call processing control device 2 in the first embodiment of the present invention.

  In FIG. 1, the call processing system 10 roughly includes a first call processing control device 1 and a second call processing control device 2. The first call processing control device 1 and the second call processing control device 2 have a function of controlling so that, for example, telephones not shown can be connected through a telephone line and a network line not shown. That is, the first call processing control device 1 and the second call processing control device 2 have a function of controlling call processing.

  In the following description, for convenience of explanation, the call processing control device (active device) operating as the active system is referred to as “first call processing control device 1”. In the following description, a call processing control device (standby device) that operates as a standby system with respect to the active system is referred to as a “second call processing control device 2”. Further, in the following description, the first call processing control device 1 and the second call processing control device 2 are collectively referred to as “call processing control device”. It is assumed that there is no difference in function and operation between the first call processing control device 1 and the second call processing control device 2 (the same applies to the following embodiments).

  More specifically, the first call processing control device 1 and the second call processing control device 2 include an application unit 3 and an intersystem synchronization unit 4.

  The application unit 3 applies a change such as a modification of software to be executed by the own device using a plug-in file application method. More specifically, for example, the application unit 3 applies the plug-in file to the intersystem synchronization unit 4 when the software change includes a change to the intersystem synchronization unit 4.

  Here, the plug-in file application method is a method in which a plug-in file that can be updated in units of binary files is applied to, for example, the inter-system synchronization unit 4 that is a software change target. . As described above, the plug-in file application method provides a function of changing (for example, adding or correcting a function) a program that can be corrected with respect to an execution process operating in the call processing control apparatus. In addition, since the plug-in file application method can limit the software change to the range necessary for the change, the file size required for the change can be reduced.

  The intersystem synchronization unit 4 executes a redundant system integration process or a redundant system disconnection (system release) process between the active system device and the standby system system (systems by the intersystem synchronization unit 4). The incorporation process and the system release process will be described later in detail in the second embodiment).

  In the following description, a redundant configuration is referred to as a “redundant configuration” for convenience of description (hereinafter, the same applies to each embodiment).

  More specifically, the inter-system synchronization unit 4 cancels the redundant configuration of the first call processing control device 1 and the second call processing control device 2. For example, the inter-system synchronization unit 4 executes a system disconnection (system release) process when the application unit 3 applies a plug-in file (that is, before application).

  Thereby, for example, when the plug-in file is applied to the second call processing control device 2, the second call processing control device 2 affects the first call processing control device 1 that executes the call processing. The plug-in file can be applied to the device without affecting the device.

  On the other hand, the intersystem synchronization unit 4 incorporates a redundant configuration of the first call processing control device 1 and the second call processing control device 2. For example, the intersystem synchronization unit 4 constructs a redundant configuration of the first call processing control device 1 and the second call processing control device 2 when the application unit 3 applies the plug-in file (that is, after application). To do.

  Next, the inter-system synchronization unit 4 executes inter-system synchronization processing between the storage unit 5 of the first call processing control device 1 and the storage unit 5 of the second call processing control device 2. That is, the inter-system synchronization unit 4 stores the storage unit of the first call processing control device 1 so that the call processing being executed in the first call processing control device 1 can be continued in the second call processing control device 2. 5 and the storage unit 5 of the second call processing control device 2 are synchronized.

  More specifically, the intersystem synchronization unit 4 of the first call processing control device 1 and the intersystem synchronization unit 4 of the second call processing control device 2 operate as an active system by cooperating with each other. Synchronization processing is executed in the storage unit 5 of the call processing control device 1 and the storage unit 5 of the second call processing control device 2 that operates as a standby system.

  Thereby, for example, when the first call processing control device 1 operating as the active system cannot execute the call processing, the second call processing control device 2 operating as the standby system continues the call processing. can do.

  Here, the case where the call processing cannot be executed is, for example, when a failure occurs in the first call processing control device 1 which is an active system, or when a maintenance operation by a maintenance person (for example, the maintenance person 40 shown in FIG. 2) is performed. Cases such as when it occurs are conceivable.

  Next, the inter-system synchronization unit 4 stops or restarts the inter-system synchronization processing between the systems of the storage unit 5 of the active system device and the storage unit 5 of the standby system device.

  More specifically, the inter-system synchronization unit 4 stops inter-system synchronization processing between the systems of the storage unit 5 of the first call processing control device 1 and the storage unit 5 of the second call processing control device 2 or Resume. For example, the inter-system synchronization unit 4 stops or restarts the system before executing the system incorporation process.

  The inter-system synchronization unit 4 executes a system switching process for switching the active system device to the standby system and switching the standby system device to the active system.

  More specifically, as an example, the inter-system synchronization unit 4 switches the first call processing control device 1 to the standby system and applies the second call processing control device 2 to the active system after the application unit 3 applies the plug-in file. System switchover processing to switch to is executed.

  Thereby, for example, when the plug-in file is applied to the second call processing control device 2, the first call processing control device 1 switched to the standby system by the system switching processing by the inter-system synchronization unit 4 is The plug-in file application process can be executed on the device itself. On the other hand, the second call processing control device 2 switched to the active system by the system switching process by the inter-system synchronization unit 4 can continue the call processing.

  The storage unit 5 is an area for storing information related to call processing. The storage unit 5 is a volatile storage device that can read and write data by a computer.

  More specifically, as an example, the storage unit 5 is an area that stores information related to call processing such as a protocol state for each call and information on a call during communication.

  As described above, according to the call processing control devices (first call processing control device 1 and second call processing control device 2) according to the present embodiment, even if these devices are in operation between different devices. Software changes can be applied more efficiently. The reason is as described below.

  In other words, the call processing control device can realize a change such as a modification of software to be executed by the own device by the plug-in file application method. In particular, the call processing control apparatus can realize a change in the type of the storage unit 5 such as a change in the size of the storage unit 5 and a change in the use and classification of the storage unit 5 by applying a plug-in file.

  Here, more specifically, an operation when a generally known call processing control apparatus applies a software change will be described.

  FIG. 5 is a sequence diagram showing an operation when a generally known call processing control apparatus applies a software change.

  In FIG. 5, the call processing system 30 includes a third call processing control device 31 that operates as an active system and a fourth call processing control device 32 that operates as a standby system.

  The fourth call processing control device 32 executes plug-in file application processing (step S21). The fourth call processing control device 32 executes a restart process (step S22, the restart process will be described later in the second embodiment). The third call processing control device 31 and the fourth call processing control device 32 execute a system switching process (step S23).

  Next, the third call processing control device 31 operating as a standby system by the system switching process executes a plug-in file application process (step S24). In addition, the third call processing control device 31 executes a restart process (step S25).

  Thus, in a generally known call processing control device, inter-system synchronization processing is performed between the storage unit of the active device and the storage unit of the standby device. For example, the type of the storage unit is changed. There has been a problem that it is impossible to execute a change related to a storage unit. That is, in a generally known call processing control apparatus, there is a limit to the range in which software can be changed.

  On the other hand, the call processing control apparatus described in the first embodiment of the present invention includes, for example, the storage unit 5 of the first call processing control apparatus 1 that operates as an active system and the second that operates as a standby system. Inter-system synchronization processing with the storage unit 5 of the call processing control device 2 can be controlled. In other words, the call processing control device described in the first embodiment can be easily applied to its own device even when the software related to the storage unit 5 is changed, such as the type change of the storage unit 5. it can.

  The call processing control apparatus described in the first embodiment of the present invention can reduce the time required for changing the software. The reason is that the call processing control apparatus changes the software by the plug-in file application method, so that the file size required for the change can be reduced. Further, since the call processing control apparatus has a small file size required for the change, the work man-hours required for software verification and application processing can be significantly reduced as compared to applying a software package. Because.

<Second Embodiment>
Next, a second embodiment based on the above-described call processing control apparatus 1 according to the first embodiment of the present invention will be described. In the following description, the characteristic part according to the present embodiment will be mainly described. At this time, the same reference numerals are assigned to the same configurations as those in the above-described embodiments, and duplicate descriptions are omitted.

  A call processing control apparatus according to a second embodiment of the present invention will be described with reference to FIGS. 2, 3A and 3B.

  FIG. 2 is a block diagram showing a configuration of the call processing system 20 including the first call processing control device 21 and the second call processing control device 22 in the second embodiment of the present invention.

  In FIG. 2, the call processing system 20 roughly includes a first call processing control device 21 and a second call processing control device 22.

  The call processing control devices (the first call processing control device 21 and the second call processing control device 22) include an application unit 23 and an intersystem synchronization unit 4.

  More specifically, the application unit 23 collects backup files and files stored in the call processing control device in response to an operation from the maintenance person 40 as compared with the application unit 3 described in the first embodiment. Various maintenance processes such as update are executed.

  The processing unit 24 executes call processing in accordance with a request from a telephone (not shown) or other call processing control device. More specifically, as an example, when executing the call processing, the processing unit 24 accesses the storage unit 5 and stores information related to call processing such as a protocol state for each call and information on a call during communication.

  Since the technology itself for executing the call processing by the processing unit 24 can be a general technology at present, a detailed description of this embodiment will be omitted (the same applies to each embodiment hereinafter).

  Next, in the following description, the operation in which the call processing control apparatus according to the present embodiment applies the software change will be described more specifically.

  3A and 3B are sequence diagrams illustrating an operation when the call processing control apparatus according to the second exemplary embodiment of the present invention applies a software change. The operation procedure of the call processing control apparatus will be described along the sequence diagram.

  In the following description, for convenience of description, as an example, the plug-in file includes a binary code that changes an access method when the processing unit 24 accesses the storage unit 5. For this reason, the plug-in file is applied to the processing unit 24. This change temporarily stops the inter-system synchronization between the storage unit 5 of the first call processing control device 21 and the storage unit 5 of the second call processing control device 22 when the plug-in file is applied. Suppose that it is necessary.

  In the following description, for convenience of explanation, as an example, the first call processing control device 21 includes the application unit 23 as the first application unit, the intersystem synchronization unit 4 as the first intersystem synchronization unit, and the storage unit 5. Is referred to as a first storage unit, and the processing unit 24 is referred to as a first processing unit. In the following description, the second call processing control device 22 includes the application unit 23 as the second application unit, the intersystem synchronization unit 4 as the second intersystem synchronization unit, the storage unit 5 as the second storage unit, and the processing. The unit 24 is referred to as a second processing unit.

  For convenience of explanation, the above-described configuration will be described as an example. However, the present invention described by taking this embodiment as an example is not limited to the configuration described above (the same applies to the following embodiments).

  First, the maintenance person 40 gives an instruction to the second call processing control device 22 to apply the plug-in file to the second call processing control device 22 operating as a standby system. That is, the call processing control device executes plug-in file application processing for the second call processing control device 22 shown in steps S1 to S5.

Step S1:
The second inter-system synchronization unit executes a system disconnection process between the first call processing control device 21 operating as the active system and the second call processing control device 22 operating as the standby system. That is, the second inter-system synchronization unit cancels the redundant configuration of the first call processing control device 21 and the second call processing control device 22.

  More specifically, the second intersystem synchronization unit transmits a cancellation notification requesting cancellation of the redundant configuration to the first intersystem synchronization unit. The first inter-system synchronization unit receives the release notification from the second inter-system synchronization unit. In accordance with the received cancellation notification, the first inter-system synchronization unit sets the system management information for managing the redundant configuration to the dual operation state between the first call processing control device 21 and the second call processing control device 22 (that is, The redundant operation state) is updated to the single operation state of only the first call processing control device 21.

  In the following description, the system management information includes information for managing the status (status) of the redundant configuration of the first call processing control device 21 and the second call processing control device 22.

Step S2:
The second application unit applies the plug-in file to the second processing unit. That is, the second application unit applies the plug-in file to the second processing unit by an input process from the maintenance person 40.

  More specifically, as an example, the second application unit starts processing according to the execution of the plug-in file input command by the maintenance person 40. That is, the second application unit expands, for example, a plug-in file arranged in a predetermined folder in the call processing control apparatus into an entity (new binary code). Next, the second application unit temporarily backs up the binary code (denoted as old binary code) being executed in the second call processing control device 22. The second application unit replaces the old binary code with the new binary code. When the second call processing control device 22 operates without any problem after applying the new binary code, the second application unit deletes the backed-up old binary code.

Step S3:
The second call processing control device 22 executes a restart process.

  More specifically, for example, when the operating system (Operating_System: hereinafter referred to as “OS”) needs to be restarted by being implemented in the call processing control device by application of a plug-in file, the second call processing control is performed. The device 22 executes a restart process. That is, the second call processing control device 22 autonomously restarts the OS after applying the plug-in file. Note that the restart process may be unnecessary depending on the contents of the software change.

Step S4:
The second inter-system synchronization unit stops inter-system synchronization between the first storage unit and the second storage unit, which is performed when the first inter-system synchronization unit and the second inter-system synchronization unit cooperate with each other. That is, the second inter-system synchronization unit executes inter-system synchronization stop processing performed between the first storage unit and the second storage unit.

  More specifically, the second inter-system synchronization unit transmits an inter-system synchronization stop request to the first inter-system synchronization unit. The first inter-system synchronization unit receives the stop request from the second inter-system synchronization unit.

  Thereby, when the system incorporation process described in step S5 is executed, the first inter-system synchronization unit and the second inter-system synchronization unit start the inter-system synchronization process between the first storage unit and the second storage unit. You can stop in advance.

Step S5:
The second inter-system synchronization unit executes system incorporation processing of the first call processing control device 21 that operates as the active system and the second call processing control device 22 that operates as the standby system. That is, the second inter-system synchronization unit constructs a redundant configuration of the first call processing control device 21 and the second call processing control device 22.

  More specifically, the second intersystem synchronization unit transmits a construction notification requesting construction of a redundant configuration to the first intersystem synchronization unit. The first inter-system synchronization unit receives the construction notification from the second inter-system synchronization unit. The first inter-system synchronization unit transmits the system management information for managing the redundant configuration from the single operation state of only the first call processing control device 21 to the first call processing control device 21 and the second in accordance with the received construction notification. The state is updated to a dual operation state (that is, a redundant operation state) with the call processing control device 22.

Step S6:
The first inter-system synchronization unit and the second inter-system synchronization unit execute a system switching process.

  More specifically, as an example, the first inter-system synchronization unit and the second inter-system synchronization unit have system management information, the active system is the first call processing control device 21, and the standby system is the second call processing. The operation system is updated to the operation state in which the active system is the second call processing control device 22 and the standby system is the first call processing control device 21 from the operation state in which the control device 22 is used. In addition, the first intersystem synchronization unit and the second intersystem synchronization unit execute a process of changing the IP address assigned to the own device.

  As a result, the first call processing control device 21 operating as the active system transitions from the active system to the standby system. On the other hand, the second call processing control device 22 operating as the standby system transitions from the standby system to the active system. That is, the second call processing control device 22 takes over the call processing from the first call processing control device 21 and continues the taken-up call processing.

  Next, the call processing control device executes plug-in file application processing for the first call processing control device 21 shown in steps S7 to S11.

  In the following description, for convenience of explanation, it is assumed that the second call processing control device 22 operates as an active system by the system switching process described in step S6. In the following description, it is assumed that the first call processing control device 21 operates as a standby system.

Step S7:
The first inter-system synchronization unit executes a system disconnection process between the first call processing control device 21 and the second call processing control device 22. That is, the first inter-system synchronization unit cancels the redundant configuration of the first call processing control device 21 and the second call processing control device 22.

  More specifically, the first inter-system synchronization unit transmits a cancellation notification requesting cancellation of the redundant configuration to the second inter-system synchronization unit. The second intersystem synchronization unit receives the release notification from the first intersystem synchronization unit. In accordance with the received cancellation notification, the second inter-system synchronization unit converts the system management information into a dual operation state between the first call processing control device 21 and the second call processing control device 22 (that is, redundant operation). State) to the single operation state of only the second call processing control device 22.

Step S8:
The first application unit applies the plug-in file to the first processing unit.

  The plug-in file application process for the first processing unit is the same as the plug-in file application process for the second processing unit described in step S2. Therefore, the overlapping description is omitted.

Step S9:
The first call processing control device 21 executes a restart process.

  The process in which the first call processing control device 21 executes the restart process is the same as the restart process performed by the second call processing control device 22 described in step S3. Therefore, the overlapping description is omitted.

Step S10:
The first inter-system synchronization unit resumes inter-system synchronization between the first storage unit and the second storage unit, which is performed when the first inter-system synchronization unit and the second inter-system synchronization unit cooperate with each other. In other words, the first inter-system synchronization unit executes inter-system synchronization restart processing performed between the first storage unit and the second storage unit.

  More specifically, the first intersystem synchronization unit transmits an intersystem synchronization restart request to the second intersystem synchronization unit. The second intersystem synchronization unit receives the restart request from the first intersystem synchronization unit.

  Thereby, when the system incorporation process described in step S11 is executed, the first inter-system synchronization unit and the second inter-system synchronization unit perform inter-system synchronization processing between the first storage unit and the second storage unit. You can resume immediately.

Step S11:
The first inter-system synchronization unit executes a system incorporation process between the second call processing control device 22 that operates as an active system and the first call processing control device 21 that operates as a standby system. In other words, the first inter-system synchronization unit constructs a redundant configuration of the first call processing control device 21 and the second call processing control device 22.

  More specifically, the first inter-system synchronization unit transmits a construction notification requesting construction of a redundant configuration to the second inter-system synchronization unit. The second intersystem synchronization unit receives the construction notification from the first intersystem synchronization unit. The second inter-system synchronization unit changes the system management information from the single operation state of the second call processing control device 22 to the first call processing control device 21 and the second call processing control device 22 according to the received construction notification. To the dual operation state (that is, the redundant operation state).

  In the above-described exemplary embodiment, for the sake of convenience of explanation, the configuration in which the application unit 23 applies the plug-in file to the processing unit 24 is described as an example. However, the embodiment according to the present invention is not limited to such a configuration. The application unit 23 may adopt a configuration in which the plug-in file is applied not only to the processing unit 24 but also to the intersystem synchronization unit 4, for example. That is, the application unit 23 may adopt a configuration in which the plug-in file is applied to at least one of the processing unit 24 and the intersystem synchronization unit 4 in accordance with the content of software change. Alternatively, the application unit 23 may adopt a configuration in which the plug-in file is applied to other units different from the processing unit 24, the intersystem synchronization unit 4, and the like according to the change contents of the software.

  As described above, according to the first call processing control device 21 and the second call processing control device 22 according to the present embodiment, the effects described in the first embodiment can be enjoyed, and further, for example, a maintenance person The convenience of 40 can be improved. The reason is as described below.

  That is, the call processing control apparatus includes an application unit 23 that executes various maintenance processes such as collection of backup files and file updates stored in the call processing control apparatus in accordance with an operation from the maintenance person 40.

(Hardware configuration example)
Each unit shown in the drawings in the embodiment described above can be regarded as a function (processing) unit (software module) of a software program. Each of these software modules may be realized by dedicated hardware.
