Description

  The present invention relates to an IP telephone system that performs external changes such as firmware upgrade of an IP (Internet Protocol) telephone.

In a conventional IP telephone system, an IP telephone and a server device are connected by a LAN (Local Area Network), and a startup program stored in a FROM unit including a flash memory which is a rewritable nonvolatile memory of the IP telephone When upgrading an application program, start program component identification information, application program component identification information, and settings from a functional component conversion table set in advance by an operation manager or the like based on coded function information transmitted from the IP telephone Extracting file part identification information, taking out the corresponding part from each part storage unit based on the respective part identification information, creating a new start program, application program and setting file by combining them, and sending IP phone Send to The IP phone stores the received new startup program and application program in the startup program storage area and application program storage area of the FROM unit, and uses the same area as the area for storing the personal settings set by the IP phone user. In the setting file storage area of the FROM section, the received setting file composed of essential settings such as the voice compression method is stored to upgrade the application program and the like (see, for example, Patent Document 1).
JP 2003-259000 A (mainly, page 8 paragraph 0038-page 9 paragraph 0050, FIG. 5)

In general, when a new application program or the like after the upgrade is written to the flash memory, the flash memory is once cleared and then the new application program or the like is written.
In addition, since flash memory generally does not have a huge memory capacity, it is difficult to assign a large memory capacity to each storage area when storing storage areas for storing application programs and the like. When the program capacity increases and the storage area becomes insufficient, it may be impossible to write a new application program or the like.

  However, in the above-described conventional technology, a startup program storage area and an application program storage area are set in the FROM unit, and a setting file storage area is set in the same area as the area for storing personal settings set by the user of the IP telephone. If the program capacity of the application program etc. at the time of version upgrade increases because it is set, the startup program storage area and application program storage area may be insufficient, and it becomes impossible to write new application programs etc. There is a problem.

  For this reason, if a new application program or the like is written after the FROM section is cleared once, the setting file storage area set in the same area as the area for storing the personal settings set by the IP telephone user is also cleared. Only the essential settings such as the received voice compression method are stored as a setting file, and the user has to reset the personal settings again.

  The present invention has been made to solve the above-described problems, and provides a means for taking over personal settings set by a user as they are even in a firmware storage unit having a limited storage capacity such as a flash memory. For the purpose.

  In order to solve the above problems, the present invention provides an IP telephone system in which an IP telephone and a centralized management terminal are connected via a network, wherein the IP telephone is configured with essential firmware settings for controlling the functions of the IP telephone. A firmware storage unit for storing a setting file comprising personal settings; means for receiving a new setting file from the centralized management terminal; and means for storing the received new setting file in the firmware storage unit. The centralized management terminal stores a change item of a setting file and a setting content thereof as change information, means for recognizing an identifier of an IP telephone that changes the contents of the setting file, Based on the identifier, means for obtaining the setting file of the IP telephone, and reading the change information from the terminal storage unit Means for creating a new setting file by writing the setting contents of the change item of the change information into the setting contents of the item of the acquired setting file; and the recognized identifier of the new setting file. Means for transmitting to the IP telephone.

  As described above, according to the present invention, the centralized management terminal acquires the original setting file of the IP phone of the change destination that needs to change the setting contents of the setting file, and newly writes the contents of the change information in the new setting file. By creating a new configuration file and storing it in the firmware storage unit of the IP phone, only the configuration file in the firmware storage unit can be rewritten. With the new setting file that inherits the personal settings, the user can immediately make a call or the like using the new setting file.

The operation of the above configuration will be described.
Hereinafter, the centralized management process according to the present embodiment will be described in accordance with the steps indicated by S using the flowchart shown in FIG.
S1, when a person in charge of the center such as a call center turns on the central management terminal 2, the terminal control unit 21 of the central management terminal 2 displays a work instruction input acceptance screen on the screen of the display unit 24 and stands by.

  A cursor indicating the input position is displayed on the business instruction input acceptance screen, and the person in charge of the center uses a keyboard or the like of the input unit 25 for a program name (for example, aaa) indicating a centralized management program and a process name (for example, processing for executing an argument) For example, bbb), a condition code indicating the acquisition destination of the setting file 8 (for example, abc, which is input only when the acquisition source is the file information database 23 in this embodiment), and the identifier of the IP telephone set 1 to be processed ( In this embodiment, an IP address) and a simultaneous code (for example, all) indicating simultaneous change are input.

For example, it is input as aaaaa / bbb / abc / 11.22.33.4.
The terminal control unit 21 that has received an instruction input from the center person in charge through the input unit 25 recognizes and activates a program to be activated by the program name (in this embodiment, a centralized management program). In addition, the application program executed with the process name is recognized as the upgrade process, and the IP phone 1 of the change destination that requires the upgrade is recognized with the input IP address.

S2, when the terminal control unit 21 that has started the centralized management program recognizes that the process name of the argument is the process name indicating the upgrade process, the terminal control unit 21 determines that the process to be executed is the upgrade process and Branches to step 4 SA1. In other cases, the process proceeds to step S3.
S3. When the terminal control unit 21 recognizes that the process name of the argument is the process name indicating the setting file change process, the terminal control unit 21 determines that the process to be executed is the setting file change process, and performs step SB1 of FIG. Branch to In other cases, the process proceeds to step S4.

S4, when the terminal control unit 21 recognizes that the instruction input from the center person in charge is an end instruction such as an end code, the central control program is ended. In other cases, the process returns to step S1 to display the work instruction input acceptance screen on the screen of the display unit 24, and waits for the next instruction input by the person in charge of the center.
In the following, the upgrade process of the present embodiment will be described according to the steps indicated by SA using the flowchart shown in FIG.

  In this embodiment, it is assumed that the new version of firmware 7 is a version in which a voice compression method is changed and a hotline function is added to immediately connect to the contact in an emergency or the like. Therefore, in the new mandatory setting information, the setting item is “sound compression method”, the setting content is the setting information with the new method name, and the setting item used for the added hotline function is “hotline”. Setting information in which the setting content is an extension number of a contact address in an emergency or the like is written.

SA1, the process to be executed is determined to be an upgrade process, and the terminal control unit 21 branched from step S2 in FIG. 3 via the connector A recognizes an argument other than the process name and sets the number of processes to “1”. This is stored in the terminal storage unit 22.
SA2, when the IP address is included in the recognized argument, the terminal control unit 21 determines that the firmware 7 has been upgraded individually and proceeds to step SA3. If the recognized argument does not include an IP address, or if a simultaneous code is included, it is determined that the upgrade is a simultaneous change and the process proceeds to step SA4.

SA3, the terminal control unit 21 determined to be an individual version upgrade, counts the number of IP addresses input as an argument, stores the counted number in the terminal storage unit 22 as an end count, and is input as an argument All the IP addresses are stored in the terminal storage unit 22, and the process proceeds to step SA5.
SA4, the terminal control unit 21 that has determined that the version has been changed at once, reads the IP address comparison table stored in the terminal storage unit 22, counts the number of the IP addresses, and stores the counted number as the end count. The information is stored in the unit 22, and all the read IP addresses are stored in the terminal storage unit 22, and the process proceeds to step SA5.

SA5, the terminal control unit 21 reads the number of processings in the terminal storage unit 22, reads out the IP address stored in the terminal storage unit 22 corresponding to the ranking of the number of processings, and changes the IP address to which the upgrade is required. It is recognized as the IP address of the IP phone 1.
Since the number of processes is “1” at this stage, the first IP address stored in the terminal storage unit 22 is read out.

In step SA6, the terminal control unit 21 that has recognized the IP address of the IP phone 1 to be changed executes an acquisition process for the firmware 7 installed in the IP phone 1 to be changed.
That is, the terminal control unit 21 transmits a firmware transmission request for requesting transmission of the firmware 7 provided in the change destination IP telephone 1 to the destination IP telephone 1 via the network 3 with the change destination IP address as the destination. Upon receiving this, the telephone control unit 5 of the IP telephone 1 reads the firmware 7 stored in the firmware storage unit 6 and transmits it to the centralized management terminal 2 via the network 3. The terminal control unit 21 receives this and acquires the firmware 7 provided in the IP phone 1 that is the change destination.

Having acquired SA7 and firmware 7, the terminal control unit 21 decodes the machine language description of the operation program, reads the version number written therein, and recognizes the version of the firmware 7 of the IP telephone set 1 to be changed.
S5, the terminal control unit 21 that has recognized the version of the firmware 7 of the IP phone 1 to be changed reads the version number of the new version stored in the terminal storage unit 22, compares it with the read version number, and reads it. If the version number is the same as the version number of the new version, the process proceeds to step SA15. If the read version number is an old version older than the version number of the new version, it is determined that version upgrade has been performed and the process proceeds to step SA9.

The terminal control unit 21 that has determined execution of SA9 and version upgrade executes acquisition processing of the setting file 8 provided in the IP phone 1 to be changed.
That is, the terminal control unit 21 transmits a setting file transmission request for requesting transmission of the setting file 8 provided in the change destination IP telephone 1 to the destination IP telephone 1 via the network 3 with the change destination IP address as the destination. Then, the telephone control unit 5 of the IP telephone 1 that has received this reads the setting file 8 stored in the firmware storage unit 6 and transmits it to the centralized management terminal 2 via the network 3. The terminal control unit 21 receives this and obtains the setting file 8 (referred to as the original setting file 8) that was installed in the IP phone 1 to be changed.

SA 10, the terminal control unit 21 that acquired the original setting file 8 temporarily stores the acquired setting file 8 in the terminal storage unit 22, and reads out the new version of firmware 7 stored in the terminal storage unit 22. Is sent to the destination IP telephone 1 via the network 3 with the destination IP address as the destination.
The telephone control unit 5 that has received the new version of the firmware 7 once clears the firmware storage unit 6, and successively writes and stores the received start program and operation program of the new version firmware 7 in the firmware storage unit 6. To do.

Since the telephone control unit 5 such as a microprocessor holds the old version firmware 7 and the setting file 8 in its storage area and executes the operation program of the IP telephone 1, the subsequent operation program is executed. There will be no hindrance.
In addition, since the original setting file 8 is transmitted and stored in advance to the centralized management terminal 2 in step SA10, the original setting file 8 is not lost.

The terminal control unit 21 that has transmitted the SA 11 and the new version of the firmware 7 reads out the new essential setting information stored in the terminal storage unit 22 and the original setting file 8 of the IP phone 1 of the change destination temporarily stored.
The SA 12 and the terminal control unit 21 read the setting item and the setting content of the read new mandatory setting information, search the setting item of the original setting file 8 to identify the corresponding setting item, and specify the specified setting item. Rewrite the setting contents of the new mandatory setting information read out.

If the setting item read from the new mandatory setting information does not exist in the setting item of the original setting file 8, the setting item and the setting content are added to the original setting file 8 and written.
These operations are repeated for the number of setting items of the new mandatory setting information read out, and a new setting file 8 in which the setting items of the new mandatory setting information and the setting contents are written in the original setting file 8 is created.

The terminal control unit 21 attaches the IP address of the change destination to the created new setting file 8 and temporarily stores it in the terminal storage unit 22.
In this embodiment, the setting contents of the setting item “audio compression method” in the original setting file 8 shown in FIG. 2 are rewritten, and a new setting item “hotline” and an extension number corresponding to the setting item are added. A new setting file 8 shown in FIG.

In step SA13, the terminal control unit 21 which has created the new setting file 8 transmits the change destination IP address to the destination IP phone 1 via the network 3 as the destination.
The telephone control unit 5 that has received the new setting file 8 writes and stores the received new setting file 8 following the firmware 7 in the firmware storage unit 6.
Then, the telephone control unit 5 storing the new setting file 8 starts the new version of the start program by restarting, holds the new version of the operation program and the new setting file 8 in the storage area, and stores the new version of the start program. The operation of the IP telephone 1 by the firmware 7 is started.

SA 14, the terminal control unit 21 that has finished transmitting the new setting file 8 reads the new setting file 8 temporarily stored in the terminal storage unit 22 and the IP address of the change destination, and a file information database based on the read IP address. The corresponding setting file 8 is identified, and the setting file 8 is rewritten to a new setting file 8 to update the file information.
SA15, the terminal control unit 21 that has finished updating the file information reads the number of ends temporarily stored in the terminal storage unit 22, and adds “1” to the number of processes when the current number of processes is less than the number of ends. Returning to step SA5, the version upgrade of the other IP telephone 1 is continued.

When the current number of processing times coincides with the number of end times, the terminal control unit 21 determines the end of the version upgrade processing, returns to step S1 in FIG. The business instruction input acceptance screen is displayed on the screen 24 and waits for the next instruction input from the center person in charge.
As described above, in the version upgrade process of this embodiment, the original setting file 8 is acquired before the firmware storage unit 6 is cleared, and only the new setting contents necessary for the new version are stored in the original setting file 8. Since the new setting item is written as the setting contents of the setting item and only the setting item and the setting contents are added to create a new setting file 8, the contents of the personal settings set in the original setting file 8 are The user can immediately make a call to the IP phone updated to the new version without resetting the personal setting by using the new setting file 8 that does not disappear and retains the personal setting that has been set. it can.

Even if the firmware storage unit 6 has a limited storage capacity, the firmware storage unit 6 is once cleared and a new version of firmware 7 and a new setting file 8 are continuously written. Even if the program capacity of 7 is increased, the new version of firmware 7 can be easily written.
In the version upgrade process of the present embodiment, the new version firmware 7 and the new setting file 8 have been described as being transmitted separately. However, the same effect as described above can be obtained even if these are transmitted together. be able to.

  Further, the count of the number of end times when it is determined that the change is simultaneous is described as counting using the IP address comparison table of the terminal storage unit 22, but all setting files stored by searching the file information database 23 are stored. It is also possible to count the number of 8 and use this as the number of end times, extract the IP addresses of all the setting files 8, and store this in the terminal storage unit 22 as the IP address of the change destination.

Hereinafter, the setting file changing process according to this embodiment will be described with reference to the flowchart shown in FIG.
SB1, the process to be executed is determined to be a setting file change process, and the terminal control unit 21 branched from step S3 in FIG. 3 via the connector B recognizes an argument other than the process name and sets the number of processes to “1”. This is set and stored in the terminal storage unit 22.

If the simultaneous argument is not included in the recognized argument, the SB2 and the terminal control unit 21 determine that the setting file 8 is individually changed and proceed to Step SB3. If the recognized argument includes a simultaneous code, it is determined that the setting file 8 has been simultaneously changed, and the process proceeds to step SB4.
The terminal control unit 21 that has determined that the SB 3 and the setting file 8 have been individually changed stores the number of completions based on the IP address input as an argument and all of the IP addresses in the terminal storage unit 22 as in step SA3. Save and move to step SB5.

In this case, if the recognized argument does not include an IP address, the number of times of termination is set to “0”, this is stored in the terminal storage unit 22, and the process proceeds to step SB5.
The terminal control unit 21 that has determined that SB4 and the setting file 8 are simultaneously changed stores the number of completions based on the IP address comparison table and all of the IP addresses in the terminal storage unit 22 in the same manner as in step SA4. Control goes to step SB5.

SB5, the terminal control unit 21 reads the end count of the terminal storage unit 22. If the end count is “0”, that is, if the IP address is not input as an argument, it is determined that the setting file 8 is changed by screen input. Control goes to step SB6. If the end count is “1” or more, it is determined that the setting file 8 is automatically changed, and the process proceeds to step SB13.
SB 6, the terminal control unit 21 that determines that the setting file change process is a change of the setting file 8 by screen input reads the template setting file from the terminal storage unit 22 and displays it on the screen of the display unit 24. Each input column of the template setting file displayed at this time is displayed as a blank column.

The person in charge of the center selects the IP address input field using the mouse of the input unit 25 and the like, and inputs the IP address of the IP phone 1 to be changed using the keyboard or the like. The terminal control unit 21 that has received this via the input unit 25 recognizes the IP address of the IP phone 1 that is the change destination for changing the setting contents of the setting file 8.
The center person in charge performs an end operation by the input unit 25 when the change of the setting file 8 by screen input is to be ended.

SB7, when the terminal control unit 21 recognizes the end input of the person in charge of the center, the process proceeds to step SB22. In other cases, the process proceeds to step SB8.
SB8, the terminal control unit 21 that has recognized the IP address of the IP phone 1 that is the change destination, if the recognized argument includes a condition code indicating the acquisition source of the setting file 8, the acquisition destination of the setting file 8 It determines with the information database 23, and transfers to step SB10. If the recognized argument does not include the condition code, the acquisition destination of the setting file 8 is determined as the IP telephone 1 corresponding to the IP address, and the process proceeds to step SB9.

In step SB9, the terminal control unit 21 that has determined that the acquisition destination of the setting file 8 is the IP phone 1, executes the acquisition process of the setting file 8 provided in the change destination IP phone 1 in the same manner as in step SA9. The original setting file 8 of the IP telephone 1 is acquired and the process proceeds to step SB11.
SB 10, the terminal control unit 21 that has determined that the acquisition source of the setting file 8 is the file information database 23, identifies the corresponding setting file 8 in the file information database 23 based on the recognized IP address, and reads the setting file 8. The original setting file 8 of the IP phone 1 to be changed is acquired, and the process proceeds to step SB11.

The terminal control unit 21 that has acquired the SB 11 and the original setting file 8 temporarily stores the setting file 8 in the terminal storage unit 22 and reads all the setting items and setting contents of the original setting file 8 to set each setting. The contents are displayed in the input field of the corresponding setting item in the model setting file.
When the setting contents of the original setting file 8 of the SB 12 and the change destination IP telephone 1 are displayed, the center person in charge selects the setting item input field of the setting item to be changed with the mouse or the like of the input unit 25 and the like. Input the setting contents. In this case, the setting items to be changed are the setting contents of all the setting items of the essential setting and the personal setting.

When setting items are added, the setting items and the setting details are input to the spare setting item input field and the setting content input field in the same manner as described above.
The person in charge of the center at this time, for example, rewrites the SIP address of the mandatory setting when the user of the IP phone 1 to be changed becomes another person due to a change, etc., erases the registered telephone number of the personal setting, or microphone A routine operation such as changing the volume level to an initial value or the center person receives a request from the user and changes the request to change the contents of the setting file 8.

This request change can be made, for example, when a new registered telephone number is set in response to a request from the user of the IP phone 1 to be changed, or the original registered telephone number of the original user requested by another person is set. For example, taking over registered telephone numbers that you want to keep.
When the person in charge of the center finishes inputting the setting contents of the setting items that need to be changed, the center person in charge performs a confirmation operation using the input unit 25. By this confirmation operation, the terminal control unit 21 accepts a change input from the person in charge of the center.

  SB13, the terminal control unit 21 that received the change input of the person in charge of the center recognizes the setting contents written in the input field of each setting item, and changes the setting contents by comparing with the original setting file temporarily stored. The extracted setting item and its setting contents and the added setting item and its setting contents are extracted, and the change information with these changed items and their setting contents are temporarily stored in the terminal storage unit 22, and the process proceeds to step SB19. .

On the other hand, the terminal control unit 21 that has determined that the setting file changing process is an automatic change of the setting file 8 changes the IP address corresponding to the rank of the number of processes to the change destination that requires the setting file 8 to be changed, as in step SA5. Is recognized as the IP address of the IP telephone 1.
Subsequent operations of Steps SB15 to SB17 are the same as the operations of Steps SB8 to SB10, and the description thereof is omitted.

SB 18, the terminal control unit 21 that has acquired the original setting file 8 temporarily stores the setting file 8 in the terminal storage unit 22, reads the setting change information from the terminal storage unit 22, and uses this as change information for the terminal storage unit 22 is temporarily stored and the process proceeds to step SB19.
The SB 19 and the terminal control unit 21 read the original setting file 8 and the change information of the change destination IP telephone 1 stored in the terminal storage unit 22, read the change items of the read change information and the setting contents thereof, The setting item of the original setting file 8 is searched to identify the corresponding setting item, and the setting content of the specified setting item is rewritten to the setting content of the change item.

Further, when the change item read from the change information does not exist in the setting item of the original setting file 8, the change item and the setting content are added to the original setting file 8 and written as the setting item and the setting content. .
These operations are repeated for the number of change information items that have been read, and a new setting file 8 in which the change information change items and the setting contents are written in the original setting file 8 is created.

The terminal control unit 21 attaches the changed IP address to the created new setting file 8 and temporarily stores it in the terminal storage unit 22.
The terminal control unit 21 that has created the SB 20 and the new setting file 8 transmits this to the destination IP telephone 1 via the network 3 with the destination IP address as the destination.
The telephone control unit 5 that has received the new setting file 8 rewrites and stores the setting file 8 in the firmware storage unit 6 into the received new setting file 8.

Then, the telephone control unit 5 storing the new setting file 8 starts the boot program of the firmware 8 by restarting, holds the new setting file 8 in its storage area, and uses the new setting file 8 to generate the IP telephone 1. Start operation.
The terminal control unit 21 that has finished transmitting the new setting file SB21 rewrites the corresponding setting file 8 in the file information database 23 to the new setting file 8 based on the IP address in the same manner as in step SA14. Update information.

The terminal control unit 21 that has finished updating the SB 22 and file information reads the number of ends temporarily stored in the terminal storage unit 22, and adds “1” to the number of processes when the current number of processes is less than the number of ends. Returning to step SB5, the setting file 8 of the other IP telephone 1 is continuously changed.
When the current processing count matches the end count, or when the end count is “0”, the terminal control unit 21 determines the end of the setting file change processing and determines the end of the setting file change processing. Returning to step S1 in FIG. 3 through the child Z, the process returns to the centralized management process, displays a work instruction input acceptance screen on the screen of the display unit 24, and waits for the next instruction input from the person in charge of the center.

  As described above, in the setting file change process of this embodiment, the original setting file 8 stored in the firmware storage unit 6 is acquired, and only the new setting contents of the change information necessary for changing the setting file 8 are obtained. Writing as the setting contents of the setting item in the original setting file 8 and creating a new setting file 8 by adding only the setting item and the setting contents to the new setting item, the setting item is set in the original setting file 8 The contents of the personal settings that have been set will not be lost, and the user can switch to the IP phone updated to the new version without resetting the personal settings by using the new setting file 8 that inherits the personal settings that have been set. Calls can be made immediately.

In addition, even when a user becomes a new user, the personal settings of the original user required can be taken over by changing the request, and the original user's personal settings can be used effectively. Become.
In addition, in the setting file changing process of the present embodiment, when changing the essential setting that is uniquely set in the IP telephone 1 such as changing the telephone number system of the extension telephone by automatic change, each IP telephone It is preferable to create a batch file in which an extension number or the like is written for each IP address and perform batch processing based on the batch file. In this way, it is possible to significantly reduce the work time in the change work of the setting file 8.

In step SB6, the center person in charge explained that the IP address of the IP phone 1 to be changed is input by using a keyboard or the like. However, based on the IP address comparison table in the terminal storage unit 22, the machine number and IP address of the IP phone 1 are used. An address pull-down menu may be created and installed in an IP address input field or the like.
As described above, in this embodiment, the terminal control unit of the centralized management terminal acquires the original setting file of the IP phone of the change destination that needs to change the setting contents of the setting file, and changes information By creating a new configuration file that contains the contents of and storing it in the firmware storage unit of the IP phone, only the configuration file in the firmware storage unit can be rewritten, and the configuration file can be changed. However, the user can immediately make a call or the like using the new setting file by using the new setting file inheriting the personal setting of the original setting file.

  In addition, change information describing the change contents of the setting file is stored in the terminal storage unit, a file information database storing the setting file of each IP telephone is provided, and the original setting file based on the IP address of the change destination And automatically creating a new setting file in which the setting contents of the setting items described in the change information are written, and storing it in the firmware storage unit of the IP phone, The same effect as described above can be obtained.

  Furthermore, the terminal control unit of the centralized management terminal acquires the firmware from the IP phone of the change destination and recognizes the version. If the recognized version is an old version, the original setting file is acquired from the IP phone of the change destination. By creating a new setting file in which the contents of the new mandatory setting information are written, and writing the new version firmware and the new setting file in the firmware storage unit of the IP phone, In addition to the same effect, even a firmware storage unit with limited storage capacity can be temporarily cleared to write a new version of firmware or a new setting file continuously. Even if the firmware program capacity increases due to the upgrade, the new version of firmware It is possible to writing easily written.

In this embodiment, the IP telephone identifier is described as an IP address. However, the IP telephone identifier is not limited to the above, and may be the IP telephone number. In short, any identifier may be used as long as it identifies an individual IP telephone and enables communication.
Further, in the setting file change processing of the present embodiment, it has been described that a new setting file is transmitted to the IP phone. However, a setting file search function is added to the IP phone firmware, and the change information is received from the centralized management terminal. The IP telephone may transmit and create a new setting file and store it in the same manner as in step SB20. Even if it does in this way, the effect similar to the above can be acquired.
