If it does, run it. In contrast, in the case of an application program not previously installed, the management module 1043 transmits the name of the application program to the UI module 1045. Then, the UI module 1045 notifies the user that the new application device has been recognized, inquires whether to download a corresponding application and driver file necessary for interworking with the application device, receives the user's download or not, and receives the management module ( 1043). If the user wants to use the application device, the management module transmits the name of the application program to the download module 1047. Then, the download module 1047 downloads the application program and the driver for the corresponding application device from the server 101 and delivers a download completion event to the management module 1043. Upon receiving the download completion event, the management module 1043 installs the corresponding application and driver in the memory device 106 and updates the application program list. Then run the application.

The Bluetooth module 107 includes a memory device 106, a microprocessor 108, and the polling program 1081.

The memory device 106 stores a driver and an application program for the application device downloaded by the wireless mobile communication module 104. Existing wireless terminals are developed with a specific application device and provided to a user in a form of embedded drivers and applications for the application device. This means that newly developed application devices cannot be used in existing wireless terminals. In order for the new application device 200 to be interoperable with the wireless terminal 100, the wireless terminal is provided with a driver and an application program for the new application device 200, and the Bluetooth module 107 provides the driver and the application program. Must have a memory device 106 that can store.

The microprocessor 108 automatically detects whether there is an application device 200 that is in close proximity periodically according to the polling program 1081, controls the memory device 106, and communicates with the wireless mobile communication module 104. Communicate The polling program 1081 is preferably stored in the nonvolatile memory 1081. The microprocessor 108 checks whether there is an application device 200 that is in close proximity periodically to automatically recognize the proximity of the application device 200 according to the polling program and to enable automatic driving of the application. do.

Next, when the microprocessor 108 discovers a new application device 200, the microprocessor 108 checks whether a driver or / and an application program of the application device 200 exists in the memory device 106. If a driver and an application program of the application device 200 are not present in the memory device 106, the microprocessor 108 is a driver or / and application program of the application device 200 as described above. The name of the application to the microprocessor 114 of the wireless mobile communication module 104, through the application device 200 of the server 101, the driver and the application of the application device 200 to the server 101 Request the application. Then, as described above, the microprocessor 114 of the wireless mobile communication module 104 retrieves a driver or / and application list and, if it is a driver or / or application already installed, the Bluetooth module 107. It is provided to the microprocessor (108) of the execution and otherwise, if not present in the driver or / and application list, the application device 200 to download the driver and application from the server 101 via the wireless Internet Enable to drive.

When the wireless terminal 100 recognizes the new application device 200, the wireless terminal downloads a driver and an application program for the application device 200 by using a wireless network and the memory device 106 of the Bluetooth module 107. Will be described in more detail with reference to FIGS. 3 and 4.

3 is a view for explaining a process of installing a driver or / and application of the found application device 200, if not installed, Figure 4 is a driver or / and application of the found application device 200 If this is already installed, it is a diagram for explaining a process of driving a driver or application. In addition, the same reference numerals are used for the same parts in FIGS. 4 and 3.

First, the microprocessor 108 of the Bluetooth module 107 inquires whether there is a new application terminal 200 periodically through the Bluetooth interface 1022 according to a polling program 1081 (S31 and S41). ).

When the new application terminal 200 discovers, the microprocessor 108 sends information about the driver or / and application program of the newly discovered application device 200, for example, a name, to the wireless mobile communication module 104. It provides (S32, S42).

Upon receiving the name of a driver or / and application from the Bluetooth module 107, the microprocessor 114 of the wireless mobile communication module 104 retrieves a list of stored applications and searches for the requested driver or / and application. Check whether there exists (S33, S34).

If the requested driver and / or application exists, the microprocessor 114 installs and executes it. Otherwise, if not present, the microprocessor 114 accesses the server 101 via a wireless data communication network. Request a driver or application. When the driver or / and application program is downloaded from the server 101 according to the request, the microprocessor 114 updates the list and drives and installs the driver or / and application program. Meanwhile, the microprocessor 114 copies the driver or application program to the memory device 106 which is a flash memory of the Bluetooth module 107 so that the driver and application program are not deleted even during discharge. Therefore, the new application device can be controlled using the driver and / or the application program of the mobile terminal 100 (S34 to S38, S43 to S45).

 As described above, the present invention improves the disadvantage that the wireless terminal and the application device cannot recognize and communicate with each other without a pre-defined communication procedure, and thus between the previously developed wireless terminal and the application device for a new service developed later. Likewise, even if the communication procedure is not established, the necessary communication protocol (driver) can be downloaded and recognized and communicated. That is, there is an advantage in that a new wireless terminal does not need to be developed when a service that is not provided at the time of developing the wireless terminal is to be provided in the future. In addition, there is no existing method of interworking an application device by a wireless terminal by itself, and the wireless terminal can automatically recognize an application device and drive an application program that works with the application device as the application device approaches. Application services are possible. In addition, the present invention can provide a wireless terminal device capable of downloading and recognizing a new communication protocol even when the communication procedure for the service between the wireless terminal and the application device is not regulated.
