Further, the PC has an operation input unit 117 and a data storage unit 118, all of which are connected to the main control unit 112. The data storage unit 8 stores software to be downloaded in advance.

FIG. 2 is a diagram showing the concept of downloading software from a PC to the above-mentioned mobile communication terminal device in the manufacturing process. Reference numeral 14 denotes a mobile mobile communication terminal device having the above-described configuration; Is a PC having a Bluetooth wireless unit and a control unit, similarly to the mobile mobile communication terminal device, and 16 is a belt conveyor for moving the mobile mobile communication terminal device 14.

In this figure, before downloading,
The PC mainly establishes a Bluetooth network (this is called a piconet in Bluetooth). In Bluetooth, a main mobile communication terminal is called a master and a slave mobile communication terminal is called a slave. In this case, the PC becomes the master, and the mobile communication terminal becomes the slave. Bluetooth is standardized so that up to seven slaves can be connected simultaneously.

The inside of the dotted line is shielded so that the mobile communication terminal and the PC can communicate only inside the dotted line.

A control procedure for downloading software in a manufacturing line as shown in FIG. 2 will be described with reference to FIG. First, after operating the belt conveyor 16,
Activate the Bluetooth means of the master PC. On the other hand, the operation input unit 7 of the mobile communication terminal device as a slave is operated to activate the Bluetooth means and put the mobile communication terminal device on the belt conveyor 16.

By the Bluetooth means, the PC serving as the master forms a piconet with respect to the mobile communication mobile communication terminal device contained in the shield case, thereby establishing a master-slave relationship. When this network is established (step 30), the PC downloads the nth software from the PC to the slave mobile communication terminal (step 32). Initially, n is set to 1.

In the case of this embodiment, one piece of software is divided into seven pieces. When the download of the first part is completed, the belt conveyor moves, and the next mobile communication terminal device is shielded. Get into the case.
At this time, a new piconet is formed from the PC, and the mobile communication terminal device that has entered the shield case is set as a slave.

In Bluetooth, signals can be multiplexed at a maximum of seven times and transmitted. Therefore, for the mobile communication terminal device in which the download of the first software part has been completed, the second step is performed in the next stage. To download the software portion, n is incremented and set to 2 (step 36). For the newly entered mobile communication terminal device, the first part is downloaded.

In this way, the mobile communication terminal determines whether or not the seventh part of the software has been normally downloaded (steps 34 and 38). Is displayed on the display section (step 40), and if the download is not performed normally, the download is failed.
Is displayed (step 42). When the completion or failure of the download is confirmed for one mobile communication terminal, the operations of the Bluetooth control unit and the radio unit of the mobile communication terminal are stopped (step 44).

FIG. 4 shows a comparison between the time required for downloading by the above method and that of the conventional method. Conventionally, since communication is one-to-one, if the time required to download to one mobile communication terminal device is n, it takes 7n hours to complete the download to seven terminal devices. .

On the other hand, the Bluetooth of the present embodiment
It can be seen that in the method using th, the download is performed in the multiplexed form as described above, so that it takes at most 2n hours.

In the above description, an example in the manufacturing process of the mobile communication terminal device has been described. However, the present invention is not limited to this, and the above-described method can be used for updating the software of the mobile communication terminal device already supplied to the user. Can be applied.

[0030]

As described above, according to the present invention, as described above, the download to the mobile communication terminal is performed by the second wireless line different from the original first wireless line of the mobile communication terminal. This eliminates the need for a cable connection in the conventional download method, and also limits the positional relationship between terminal devices such as facing each other in the conventional infrared communication method.
