Description

  The present invention relates to a terminal software update device for updating software stored in a mobile terminal, a terminal software update system having the mobile terminal and the terminal software update device, and terminal software update performed in the terminal software update device With respect to methods.

  Conventionally, it has been proposed to update software such as programs stored in a mobile terminal by causing the mobile terminal to download new software from a server storing various software. For example, Patent Document 1 discloses a mobile communication system that performs such downloading.

  In this mobile communication system, when it is necessary to upgrade the version of the mobile phone terminal program, the download control device first extracts the mobile phone terminals to be downloaded and starts the download for them to the exchange station device. Instruct. Next, the switching center apparatus executes download for the mobile telephone terminal. Then, the mobile telephone terminal sequentially stores the transmitted program, and when reception of necessary data is completed, the current main program is erased and a new program is written.

  In recent years, the number of software updates such as programs stored in a mobile terminal has been increasing year by year as the mobile terminal becomes more sophisticated and multifunctional. In particular, when a problem that may occur at the time of payment using a credit card function or an electronic money function of a mobile terminal is found, an immediate update of software is necessary as a process to be performed with a relatively high priority.

  A detailed method of software update currently performed in FOMA (registered trademark), which is a mobile communication service having many subscribers, will be described with reference to FIG. First, the subscriber information holding node 10 updates subscriber information (Version information) about a subscriber who uses a mobile terminal (hereinafter referred to as an update target terminal M) to be updated to the Push server 20 once a day. Update information as a difference is transmitted, and the Push server 20 receives and acquires the update information from the TISCP (step T1).

  Next, on the basis of this update information, the Push server 20 activates Push as an instruction for starting update processing in the update target terminal M that needs to be updated to the SMS gateway 30 (that is, Push of the instruction signal). Transmission) (step T2). Then, the SMS gateway 30 creates and transmits a short message as an instruction for starting update processing to the NW 40 as a communication network using SMS (ie, a short message service) (step T3). .

  Next, when the update target terminal M receives this short message via the NW 40 (step T4), it performs communication connection with the download server 50 by wireless communication, and updates the software (step T5).

  In addition, when further update is performed in the above subscriber information after the Push activation shown in Step T2 and a further difference occurs, the Push server 20 further updates the subscriber information as a further difference.

FIG. 2 is a functional configuration diagram for explaining the outline of the main functional configuration of the update management server 1, and FIG. 3 is a physical configuration diagram for explaining the outline of the main physical configuration of the update management server 1. is there. The update management server 1 is a communication device that updates (that is, updates) software stored in a mobile terminal by performing wireless communication with the mobile terminal such as a mobile phone or a PDA (Personal Digital Assistant). In particular, the update management server 1 automatically and reliably updates (or re-updates in some cases) software stored in a mobile terminal that has failed to update software or in an unupdated mobile terminal.

  As shown in FIG. 3, the update management server 1 includes a CPU 101 (Central Processing Unit) as main physical components, a RAM 102 (Random Access Memory) and ROM 103 (Read Only Memory) as main storage devices, and communication. The computer is configured as a computer including a communication module 104 for performing, and hardware such as an auxiliary storage device 105 such as a hard disk. The function of the update management server 1 is exhibited by the operation of these components. As shown in FIG. 2, the update management server 1 includes, as main functional components, a synchronization processing unit 11 (acquisition unit), an update terminal selection unit 12 (selection unit), and an update instruction unit 13. (Updating means).

  The synchronization processing unit 11 performs data synchronization processing with the mobile terminal when use of the mobile terminal is started or when a malfunction in the software stored in the mobile terminal is detected, and a terminal related to the mobile terminal This is the part that acquires information. In the terminal information, for example, software version information stored in the mobile terminal, a telephone number assigned to the mobile terminal by inserting a SIM card, or the like, allocated when the mobile terminal was manufactured by the terminal manufacturer The manufacturer serial number, the model name and submodel name of the mobile terminal, the location information of the mobile terminal, and the like are included. The acquired terminal information is stored in a database that the update management server 1 has.

  The update-necessary terminal selection unit 12 is a part that selectively extracts and recognizes and recognizes a mobile terminal that requires software update based on the terminal information (for example, the above-described software version information) acquired by the synchronization processing unit 11. is there. For example, the update terminal selection unit 12 may select a mobile terminal that is in communication with the outside as a mobile terminal that requires software update, and may select a mobile terminal that exists in an out-of-communication area. The mobile terminal may need to be updated.

  The update instruction unit 13 is a part that performs an update process for updating the software stored in the mobile terminal selected by the update terminal selection unit 12. The update process performed by the update instruction unit 13 is performed by the push server 2, the SMS gateway 3, the NW 4, and the download server 5 described later in cooperation with each other based on an instruction signal from the update instruction unit 13. Details of this update process will be described later.

(2) Update Process Next, the update process performed by the update instruction unit 13 will be described with reference to FIG. FIG. 4 is a process explanatory diagram for explaining the outline of the update process performed by the update instruction unit 13. This update process is performed in the terminal software update system 100 including the update management server 1. The terminal software update system 100 includes an update management server 1, a push server 2, an SMS gateway 3, an NW 4, a download server 5, and an update target terminal M as a mobile terminal. First, the update instructing unit 13 of the update management server 1 has no subscriber information (no version information) about a subscriber who uses a mobile terminal to be updated (hereinafter referred to as an update target terminal M) with respect to the push server 2. ) Is transmitted, and the Push server 2 receives and acquires it (step S1).

  Next, on the basis of this update information, the Push server 2 activates Push as an instruction for starting update processing in the update target terminal M that needs to be updated to the SMS gateway 3 (that is, Push of the instruction signal). Transmission) (step S2). Then, the SMS gateway 3 creates and transmits a short message as an instruction for starting the update process to the NW 4 as the communication network using the SMS (that is, the short message service) (step S3). .

  Next, when the update target terminal M receives this short message via the NW 4 (step S4), the update target terminal M performs a communication connection by wireless communication with the download server 5 to update the software (step S5). Then, the download server 5 transmits information about the update target terminal M that has been successfully updated and information about the update target terminal M that has failed to be updated to the update management server 1 (step S6).

(3) First Example of Flow of Update Process Performed by Update Management Server 1 Next, a first example of the flow of update process (terminal software update method) performed by the update management server 1 will be described with reference to FIG. FIG. 5 is a flowchart for explaining a first example of the flow of update processing performed by the update management server 1. First, the synchronization processing unit 11 detects a defect in a software program stored in some mobile terminals, and recognizes that a relatively high priority update is necessary (step S01). Detection of a defect in the synchronization processing unit 11 is performed, for example, by input setting of defect occurrence information by a telecommunications carrier that has received notification that there is a defect from a terminal manufacturer.

  Next, when the use starts such as when the mobile terminal is purchased, the synchronization processing unit 11 performs data synchronization processing with all the mobile terminals that start use, and acquires terminal information related to these mobile terminals ( Step S02, acquisition step). Based on the terminal information acquired by the synchronization processing unit 11, the update-necessary terminal selection unit 12 narrows down and selects the update target terminals M as defective terminals that need to be updated by the software program (step S03, Selection step).

  Next, the update instruction unit 13 starts execution of the update process described above for updating the software stored in the update target terminal M selected by the update required terminal selection unit 12. As described above, in this update process, the Push server 2 uses the SMS as an instruction to cause the SMS gateway 3 to start the update process in the update target terminal M that needs to be updated based on the update information described above. Push activation (that is, push transmission of an instruction signal) is performed (step S04, update step). Then, the SMS gateway 3 creates and transmits a short message as an instruction for starting the update process to the NW 4 as a communication network using SMS (that is, a short message service). This short message is transmitted from the NW 4 to the update target terminal M.

  Here, the update required terminal selection unit 12 determines whether or not the update target terminal M is in a state of being in communication with the outside or in a state outside the communication area (step S05). If it is determined that the communication is being performed with the outside or is present in an area outside the communication range, the process proceeds to step S06 described below. On the other hand, if it is determined that neither the outside communication state nor the outside communication area is present, the process proceeds to step S11 described later.

  In step S11, the update target terminal M receives the above short message via the NW 4, and on this occasion, the update target terminal M performs a communication connection by wireless communication with the download server 5 and tries to update the software. Then, the download server 5 transmits information regarding the update target terminal M that has been successfully updated to the update management server 1. And the update required terminal selection part 12 of the update management server 1 determines whether the update was completed normally (step S12). If it is determined that the update has been completed normally, a series of processing ends. On the other hand, when it is not determined that the update has been normally completed (that is, it is determined that the update has failed), the process proceeds to step S07 described later.

  In step S06, the update-necessary terminal selection unit 12 determines that the software update has failed and is impossible. Then, the process proceeds to step S07 described later.

  In step S07, the synchronization processing unit 11 performs data synchronization processing with the update target terminal M determined to have failed in the software update, and acquires terminal information regarding the update target terminal M (acquisition step). Based on the terminal information acquired by the synchronization processing unit 11, the update-necessary terminal selection unit 12 narrows down and selects the update target terminals M as defective terminals for which the update of the software program has not been completed (step). S08, selection step). And it transfers to above-described step S04. As described above, the update process is repeated an infinite number of times until the update process is successful. Therefore, when the software program can be updated immediately, the update can be performed in the shortest time.

(4) Flow of Update Process in Entire Terminal Software Update System 100 Including Update Management Server 1 Subsequently, the flow of update process in the entire terminal software update system 100 including the update management server 1 will be described with reference to FIG. . FIG. 6 is a sequence diagram for explaining the flow of update processing in the entire terminal software update system 100 including the update management server 1. First, the synchronization processing unit 11 of the update management server 1 detects a problem in a software program stored in some mobile terminals and recognizes that an update is necessary. Detection of a defect in the synchronization processing unit 11 is performed, for example, by input setting of defect occurrence information by a telecommunications carrier that has received notification that there is a defect from a terminal manufacturer.

  Next, when the synchronization processing unit 11 of the update management server 1 starts using such as when purchasing a mobile terminal, it performs data synchronization processing with all the mobile terminals that start using, and terminals related to these mobile terminals. Information is acquired (step S21, acquisition step). Then, the update-necessary terminal selection unit 12 of the update management server 1 selects and selects the update target terminals M as defective terminals that require the software program update based on the terminal information acquired by the synchronization processing unit 11. To do. Further, the update instruction unit 13 of the update management server 1 sets a DL patch program downloaded by the update target terminal M to update the software in the download server 5 (step S22).

  Next, the update instruction unit 13 of the update management server 1 starts execution of the above update process for updating the software stored in the update target terminal M selected by the update required terminal selection unit 12. As described above, in this update process, the update instructing unit 13 of the update management server 1 notifies the push server 2 of subscriber information (version information is about subscribers who use the update target terminal M to be updated). Update information as a difference of (none) is transmitted, and the Push server 2 receives and acquires it (step S23).

  Next, based on the update information described above, the Push server 2 activates SMS Push as an instruction for starting update processing in the update target terminal M that needs updating to the SMS gateway 3 (that is, SMS Push). request) (step S24, update step). Then, the SMS gateway 3 creates and transmits a short message as an instruction for starting the update process to the NW 4 as a communication network using SMS (that is, a short message service). This short message is transmitted from the NW 4 to the update target terminal M (that is, SMS Push, step S25).

  Here, it is assumed that the update required terminal selection unit 12 of the update management server 1 determines that the update target terminal M is neither in communication with the outside nor in a state outside the communication area. At this time, the update target terminal M receives the above short message via the NW 4, and then triggers the communication connection by wireless communication with the download server 5 to download the software (that is, the above-described patch). Thus, the update is performed (step S26).

  Then, the download server 5 transmits information about the update target terminal M that has been successfully updated and information about the update target terminal M that has failed to be updated to the update management server 1. And the update required terminal selection part 12 of the update management server 1 determines whether the update was completed normally. Here, it is assumed that some of the update target terminals M cannot download the above-described patch and have failed to update.

  At this time, the synchronization processing unit 11 of the update management server 1 performs data synchronization processing with the update target terminal M determined to have failed in the software update, and acquires terminal information regarding the update target terminal M (step S27). , Acquisition step). Based on the terminal information acquired by the synchronization processing unit 11, the update required terminal selection unit 12 of the update management server 1 narrows down the update target terminals M as defective terminals for which the update of the software program has not been completed. Select with.

  Next, the update instruction unit 13 of the update management server 1 starts execution of the above update process for updating the software stored in the update target terminal M selected by the update required terminal selection unit 12. As described above, in this update process, the update instructing unit 13 of the update management server 1 notifies the push server 2 of subscriber information (version information is about subscribers who use the update target terminal M to be updated). Update information as a difference of (none) is transmitted, and the Push server 2 receives and acquires it (step S28).

  Next, based on the update information described above, the Push server 2 activates SMS Push as an instruction for starting update processing in the update target terminal M that needs updating to the SMS gateway 3 (that is, SMS Push). request) (step S29, update step). Then, the SMS gateway 3 creates and transmits a short message as an instruction for starting the update process to the NW 4 as a communication network using SMS (that is, a short message service). This short message is transmitted from the NW 4 to the update target terminal M (that is, SMS Push, step S30).

  Here, it is assumed that the update required terminal selection unit 12 of the update management server 1 determines that the update target terminal M is neither in communication with the outside nor in a state outside the communication area. At this time, the update target terminal M receives the above short message via the NW 4, and then triggers the communication connection by wireless communication with the download server 5 to download the software (that is, the above-described patch). Thus, the update is performed (step S31). In addition, the step group shown by step S27-step S31 enclosed by the frame line is a step group for performing automatic re-update.

(5) Second Example of Flow of Update Process Performed by Update Management Server 1 Next, a second example of the flow of update process (terminal software update method) performed by the update management server 1 will be described with reference to FIG. FIG. 7 is a flowchart for explaining a second example of the flow of update processing performed by the update management server 1. First, the synchronization processing unit 11 detects a defect in a software program stored in some mobile terminals and recognizes that an update is necessary (step S41). Detection of a defect in the synchronization processing unit 11 is performed, for example, by input setting of defect occurrence information by a telecommunications carrier that has received notification that there is a defect from a terminal manufacturer.

  Next, the update instruction unit 13 performs software update processing that has been performed in the past (step S42). Then, the update instructing unit 13 performs the software re-update process that has been performed on the mobile terminal that failed to be updated in step S42 (step S43). In this way, by performing the previous update in advance, the number of data synchronization processes shown in FIG. 5 can be reduced. As a result, the traffic load on the network can be suppressed.

  Next, the synchronization processing unit 11 performs data synchronization processing with all the mobile terminals that start use, particularly when the use starts, such as when purchasing mobile terminals, and acquires terminal information about these mobile terminals. (Step S44, acquisition step). Based on the terminal information acquired by the synchronization processing unit 11, the update-necessary terminal selection unit 12 narrows down and selects the update target terminals M as defective terminals for which the update of the software program has not been completed (step S45). , Selection step).

  Next, the update instruction unit 13 starts execution of the update process described above for updating the software stored in the update target terminal M selected by the update required terminal selection unit 12. As described above, in this update process, the Push server 2 instructs the SMS gateway 3 to start the update process in the update target terminal M that has not been updated, based on the update information described above. SMS Push is activated (ie, Push transmission of the instruction signal) (step S46, update step). Then, the SMS gateway 3 creates and transmits a short message as an instruction for starting the update process to the NW 4 as a communication network using SMS (that is, a short message service). This short message is transmitted from the NW 4 to the update target terminal M.

  Here, the update required terminal selection unit 12 determines whether or not the update target terminal M is in a state of being in communication with the outside or in a state outside the communication area (step S47). If it is determined that the communication is being performed with the outside or is present in an area outside the communication range, the process proceeds to step S48 described later. On the other hand, if it is determined that neither the outside communication state nor the outside communication area is present, the process proceeds to step S51 described later.

  In step S51, the update target terminal M receives the above short message via the NW 4, and on this occasion, the update target terminal M performs a communication connection by wireless communication with the download server 5 and tries to update the software. Then, the download server 5 transmits information regarding the update target terminal M that has been successfully updated to the update management server 1. And the update required terminal selection part 12 of the update management server 1 determines whether the update was completed normally (step S52). If it is determined that the update has been completed normally, a series of processing ends. On the other hand, if it is not determined that the update has been normally completed (that is, it is determined that the update has failed), the process proceeds to step S44. As described above, the update process is repeated an infinite number of times until the update process is successful. Therefore, when the software program can be updated immediately, the update can be performed in the shortest time.

  In step S48, the update required terminal selection unit 12 determines that the software update has failed and is impossible. And it transfers to said step S44. As described above, the update process is repeated an infinite number of times until the update process is successful. Therefore, when the software program can be updated immediately, the update can be performed in the shortest time.

(6) Operation and effect of the present invention The update management server 1 as the terminal software update device according to the present embodiment first acquires terminal information related to the mobile terminal, and software update is performed based on the acquired terminal information. The necessary update target terminal M is selectively extracted and recognized. Then, the software stored in the selected update target terminal M is updated. Thus, in order to select and update the update target terminal M that requires software update based on the acquired terminal information, the update target terminal M in a state that requires immediate software update is appropriately selected. As a result, it is possible to perform immediate update as quickly as possible in the shortest time and without fail in updating.

  Further, as described above, since the update process is repeated an infinite number of times until the update process is successful, an immediate update is possible in the shortest time when the software program can be immediately updated. For this reason, even if there is a difference in the subscriber information regarding the subscriber who uses the update target terminal M or the update fails because the patch cannot be downloaded, the response to the Push activation performed by the Push server 2 is sent to the SMS. Even when there is no gateway 3, an immediate update can be performed in the shortest time when the update becomes possible.

  Further, since the terminal information from the beginning of the use of the update target terminal M is acquired, the necessary update is not performed even though the use of the update target terminal M is started. Can be prevented.

  In addition, even when there is an update target terminal M that cannot be updated because of the communication status at the present time, it can be selected as the update target terminal M that needs to be updated. Become. As a result, when the software can be updated, the immediate update can be performed more reliably in the shortest time.

  In addition, even if there is an update target terminal M that cannot be updated because the software is currently in an out-of-communication area, it is selected as the update target terminal M that requires software update. It becomes possible to keep. As a result, when the software can be updated, the immediate update can be performed more reliably in the shortest time.

(7) Modified Example In the above embodiment, as illustrated in FIG. 4, the update management server 1 and the push server 2 have been described as being configured separately, but a push server having the function of the update management server 1 is used. The terminal software update device according to the present embodiment may be configured as an embodiment.

  According to the present invention, it is possible to provide a terminal software update device, a terminal software update system, and a terminal software update method that enable immediate update more reliably in a state where an immediate update of software is necessary.
