(First embodiment)
FIG. 2 is a diagram showing a configuration of a communication system including the mobile terminal device and the server according to the first embodiment of the present invention. The communication system 100 includes a plurality of mobile terminal devices 10 such as mobile phones and a server 20. For example, near field communication is performed between the plurality of mobile terminal devices 10 and the server 20 by a communication method defined by, for example, the Bluetooth standard. An example of a profile used in short-range wireless communication is a personal area network (PAN) profile. However, the profile is not particularly limited as long as it is a protocol that can simultaneously connect a plurality of mobile terminal devices 10 and the server 20 and can perform communication.

  As illustrated in FIG. 3A, the mobile terminal device 10 includes a wireless transmission / reception unit 11, a Bluetooth communication unit 12, a CPU 13, a ROM 14, a RAM 15, a microphone 16, a speaker 17, a display unit 18, And an operation unit 19.

  The wireless transmission / reception unit 11 transmits / receives a wireless signal via an antenna, and demodulates and modulates the signal in order to make a call or the like. The Bluetooth communication unit 12 transmits / receives a radio signal using a communication method defined by the Bluetooth standard via an antenna, performs short-range wireless communication with the server 20, and performs demodulation and modulation of the signal according to the Bluetooth standard. .

  The CPU 13 controls the operation of each unit in the mobile terminal device 10, and includes, for example, a communication control unit 13A, a determination unit 13B, and a software acquisition unit 13C. The ROM 14 is a rewritable ROM (for example, flash memory, EEPROM), and stores software to be rewritten that is executed by the CPU 13. The ROM 14 may be arranged as many as the number of target software. The RAM 15 is used as a work area for the CPU 13 and stores data necessary for the execution of the CPU 13. Here, it is assumed that the target software in which the software to be rewritten is upgraded is stored in the server 20. In addition, since the version upgrade assumes what accompanies software development, as the user of the portable terminal device 10, the developer etc. who check the operation | movement of software for every version upgrade are mentioned.

  The microphone 16 and the speaker 17 perform input and output of sound during a call, for example. The display unit 18 is an LCD (Liquid Crystal Display) or the like, and displays various types of information. The operation unit 19 includes operation keys such as a numeric keypad, and outputs an instruction signal to the CPU 13 when pressed by the user.

  The communication control unit 13 </ b> A in the CPU 13 performs pairing via the Bluetooth communication unit 12 in response to an instruction signal from the operation unit 19, for example, a signal requesting establishment of short-range wireless communication with the server 20. Perform the action. Here, the pairing operation refers to an operation for setting the connection destination of the short-range wireless communication as the server 20. The determination unit 13 </ b> B determines whether the target software is stored in the server 20 via the Bluetooth communication unit 12 after the pairing with the server 20 is established. Furthermore, when the determination unit 13B determines that the target software is stored in the server 20, the software acquisition unit 13C receives the target software from the server 20 via the Bluetooth communication unit 12, and stores the target software in the ROM 14. Rewrite the software.

  As shown in FIG. 3B, the server 20 includes a Bluetooth communication unit 21, a CPU 22, and a ROM 23. The Bluetooth communication unit 21 performs short-range wireless communication with the mobile terminal device 10. The CPU 22 controls the Bluetooth communication unit 21 and the ROM 23 in the server 20, and includes a communication control unit 24 and a software providing unit 25. The ROM 23 is a rewritable ROM and stores target software. Further, the communication control unit 24 in the server 20 establishes short-range wireless communication with the mobile terminal device 10 via the Bluetooth communication unit 21 in response to a pairing request from the mobile terminal device 10. Further, when receiving a software provision request from the mobile terminal device 10 via the Bluetooth communication unit 21, the software providing unit 25 reads the target software from the ROM 23 and provides the target software to the mobile terminal device 10 via the Bluetooth communication unit 21.

First, when the key of the operation unit 19 is pressed, the CPU 13 controls the display unit 18 to display a menu indicating software rewriting ON for performing software rewriting (step S10). When the displayed menu is selected by pressing a key, the CPU 13 sets the software rewriting function to ON (step S11). Subsequently, the communication control unit 13A of the CPU 13 performs a pairing operation by Bluetooth with the server 20 as a connection destination via the Bluetooth communication unit 12 (step S12).

  Next, the communication control unit 13A determines whether or not pairing has been established by the pairing operation in step S12 (step S13). If pairing is not established (N), a retry process is executed (step S13). Steps S14 and S15). In step S14, m is set in advance as the upper limit of the number of retries, and when the number of retries exceeds m (N), the communication control unit 13A stops the flow as abnormal termination (step S18). For this reason, it is possible to prevent jamming due to retry execution. On the other hand, if the number of retries is less than m times in step S14 (Y), the communication control unit 13A executes a retry process in step S15.

  When pairing is established in step S13 (Y), short-range wireless communication with Bluetooth becomes possible. Subsequently, the determination unit 13B of the CPU 13 accesses the server 20 via the Bluetooth communication unit 12, and determines whether the target software is stored in the server 20 (step S16). This determination can be made by preparing in advance on the server 20 side a flag indicating that the target software exists in the server 20. As an example, the determination unit 13B determines that the target software exists in the server 20 if the flag value is “1” for the corresponding version of the designated software, and does not exist if the value is “0”. Is determined.

  If the determination unit 13B determines in step S16 that the target software exists in the server 20 (Y), the software acquisition unit 13C of the CPU 13 executes software rewriting (step S17). In step S <b> 17, the software acquisition unit 13 </ b> C receives the target software from the server 20 via the Bluetooth communication unit 12 and stores the received target software in the ROM 14. When the software acquisition unit 13C executes software rewriting in step S17, the flow ends (step S18). Further, when the determination unit 13B determines in step S16 that the target software does not exist in the server 20, the flow is also terminated.

  Next, the operation of the server 20 will be described with reference to FIG. First, the communication control part 24 of the server 20 receives the signal which shows the pairing request | requirement from the portable terminal device 10 with execution of the pairing operation | movement by said step S12 (step S20). Subsequently, in response to the pairing request, the communication control unit 24 of the server 20 establishes short-range wireless communication by Bluetooth with the mobile terminal device 10 via the Bluetooth communication unit 21 of the server 20 (step S21). ).

  Next, the software provision unit 25 of the server 20 receives a software provision request from the mobile terminal device 10 via the Bluetooth communication unit 21 in accordance with the rewriting of the software in step S17 (step S22). Subsequently, the software providing unit 25 of the server 20 reads the target software from the ROM 23 of the server 20 (step S23), and provides the target software to the mobile terminal device 10 via the Bluetooth communication unit 21 (step S24).

  Thereafter, the portable terminal device 10 executes steps S17 and S18. After that, the operation check of the target software provided from the server 20 to the mobile terminal device 10 is performed by a developer or the like.

  Next, a communication system including a portable terminal device and a server as a comparative example will be described with reference to FIG. The communication system 200 includes a plurality of mobile terminal devices 30, a server 31, and a jig 32. The server 31 stores and transfers the target software. The jig 32 is used to rewrite software to be rewritten stored in a plurality of portable terminal devices 30. As illustrated, the jig 32 is connected to the plurality of portable terminal devices 30 via cables. In addition, the connection with the cable of the some portable terminal device 30 and the jig | tool 32 is performed manually.

  In the communication system 200, the target software is transmitted from the server 31 to the mobile terminal device 30 via the jig 32, so that software to be rewritten on the plurality of mobile terminal devices 30 can be rewritten at the same time. However, this communication system 200 has the following problems.

  First, since it is necessary to physically connect a plurality of portable terminal devices 30 and jigs 32 with cables, it becomes a burden on the operator, further requires work time, and if the number of times of software rewriting increases, the connector There is a risk of damage. In addition, since there is an upper limit to the number of portable terminal devices 30 that can be connected to the jig 32 due to electric capacity limitations or the like, in order to rewrite a large amount of software of the portable terminal devices 30, the portable terminals shown in FIG. It is necessary to prepare a plurality of systems including the device 30 and the jig 32. As a result, the equipment cost increases.

  On the other hand, in the mobile terminal device 10 according to the present embodiment, after the pairing with the server 20 is established, the server 20 is accessed to determine whether the target software is stored in the server 20. The target software can be acquired using short-range wireless communication. For this reason, the portable terminal device 10 can easily acquire the target software from the server 20 and rewrite the software. Further, the server 20 can provide the target software to the mobile terminal device 10 in response to a software provision request from the mobile terminal device 10.

(Second Embodiment)
FIG. 6 is a diagram showing a communication system including a mobile terminal device and a server according to the second embodiment of the present invention. The communication system 100A is shown in the first embodiment in that it includes a software compilation machine 27 connected to the server 20A via the LAN environment 26 in addition to the plurality of mobile terminal devices 10A and the server 20A. Different from the communication system 100. The software compilation machine 27 is a device that creates target software upon receiving a command for creating target software from the server 20A. That is, the communication system 100A assumes a situation where the target software is not stored in the server 20A. Hereinafter, operations of the mobile terminal device 10A and the server 20A will be described with reference to FIG.

  FIG. 7A is a flowchart showing the operation of the mobile terminal device 10A. The operation of the mobile terminal device 10A is shown in FIG. 4A in that the process is repeatedly executed (waited) until it is determined in step S16A that the target software is stored in the server 20A (Y). The operation of the portable terminal device 10 is different. Since other processes and configurations are the same, redundant description will be omitted as appropriate.

  In the process of step S16A, when the determination unit 13B illustrated in FIG. 3A determines that the target software is not stored in the server 20A (N), the software acquisition unit 13C transmits to the server 20A via the Bluetooth communication unit 12.

In step S22 shown in FIG. 4B, after receiving a request for acquiring the target software, that is, a software provision request from the mobile terminal device 10A, the processes of steps S30 to S33 are added. This is different from the operation of the server 20. The processes in steps S30 to S33 are executed while the mobile terminal device 10A is waiting in step S16A.

  When the server 20A receives the software provision request in step S22, for example, the software provision unit 25 shown in FIG. 3B determines whether the target software is stored in the ROM 23 (step S30). If the target software is not stored in the ROM 23 (N), the software providing unit 25 transmits a command for instructing creation of the target software to the software compiling machine 27 via the LAN environment 26 (step S31).

  The software compiling machine 27 creates target software in accordance with a command from the server 20A, and transfers the target software to the server 20A via the LAN environment 26. Subsequently, the server 20A receives the target software transferred from the software compiling machine 27 (step S32). The received target software is stored in the ROM 23 by the software providing unit 25. Further, after completing the transfer of the target software, the software compiling machine 27 transmits a flag indicating that the target software exists on the server to the server 20A.

  The server 20A receives the flag transmitted from the soft compilation machine 27 (step S33), and sets the flag to a format recognizable from the mobile terminal device 10A. At this point, the mobile terminal device 10A recognizes that the target software exists on the server in the process of step S16A, ends the waiting, and proceeds to the software rewrite process of step S17. If the target software is stored in the ROM 23 in step S30 (Y), the process proceeds to step S23.

  In the server 20A, the software providing unit 25 reads the target software created by the software compiling machine 27 from the ROM 23 in accordance with the process of step S17 of the mobile terminal device 10A (step S23). Next, the software providing unit 25 provides the read target software to the mobile terminal device 10A via the Bluetooth communication unit 21 (step S24).

  In the present embodiment, in addition to the effects of the first embodiment, even when the target software is not stored in the server 20A, the target software is automatically created by the software compilation machine 27. For this reason, it is not necessary for the worker or the like to store the target software in the server, and the software can be rewritten without human intervention even when the number of workers is small, for example, at night. Therefore, it is possible to improve work efficiency in the software development stage.

  In each of the embodiments described above, an example in which the servers 20 and 20A are used in the development stage of software installed in the mobile terminal devices 10 and 10A has been described, but the present invention is not limited to this. As an example, if the software can be provided to a general user as a product through a development stage, the general user may be able to access the servers 20 and 20A. In this way, since a general user can execute software rewriting using the servers 20 and 20A, it is not time-consuming.

  Moreover, in each said embodiment, although Bluetooth was illustrated as near field communication, it is not restricted to this, You may utilize wireless LAN. Even in this case, the mobile terminal devices 10 and 10A can acquire the target software from the servers 20 and 20A after the short-range wireless communication by the wireless LAN is established, as in the above embodiments. The servers 20 and 20A can also provide the target software to the mobile terminal devices 10 and 10A using the wireless LAN.

  Further, in each of the above embodiments, the servers 20 and 20A receive the software provision request from the mobile terminal devices 10 and 10A and provide the target software. However, the present invention is not limited to this. As an example, the servers 20 and 20A store a plurality of versions (versions) of software for at least one software.
