If there is a response to this radio wave from another terminal device T2, a connection request is transmitted. When the other terminal apparatus T2 receives the connection request, the other terminal apparatus T2 transmits a connection confirmation to accept the connection if it is a preset partner. If the other party is not set, the connection is refused.

  Next, the mobile terminal device T1 transmits a function request, and confirms the function, status, and the like of the counterpart terminal (another terminal device T2). In response to a function request from the portable terminal device T1, the other terminal device T2 returns a function response indicating the function of the own terminal (other terminal device T2), for example, a function of a personal computer, a digital camera, a printer, or the like. . By this reply, the mobile terminal device T1 transmits a directory request specifying a preset directory in order to transmit a file. The other terminal device T2 that has received the directory request checks whether there is a designated directory, and returns the capacity of the disk, memory, etc. as a directory response.

  Receiving the directory response, the mobile terminal device T1 transmits a file transfer start command and starts actual file transfer. When the file transfer ends, a file transfer end command is transmitted and a disconnection request is transmitted. The other terminal device T2 that has received the disconnection request transmits a disconnection confirmation. Receiving the disconnection confirmation, the mobile terminal device T1 ends the communication and ends the process.

  Next, a file transfer transmission process in the mobile terminal device T1 will be described.

  FIG. 3 is a flowchart showing an operation in which the portable terminal device T1 performs file transfer as the transmission side.

  Note that before the file transfer process is performed, settings for wireless communication are performed in advance between the mobile terminal device T1 and the other terminal device T2.

Wait for. When the wireless communication unit 9 receives a response from the other terminal device T2, in step S2, the wireless communication unit 9 transmits a connection request command.

  In step S3, reception of a response from another terminal device T2 is awaited. If a response is received, it will be judged whether the response is a connection confirmation in step S4. If the capacity of the hard disk, memory, etc. is small, if no prior settings have been made, or if some kind of failure has occurred, a connection rejection response will be sent from the other terminal device T2. In this case Returns to step S1 and continues the detection process of the other terminal device T2.

  In step S4, when it is confirmed that the response from the other terminal device T2 is a connection confirmation, the process proceeds to step S5, and a function request command for knowing the function and status of the other terminal device T2 is transmitted by wireless communication. Transmit from unit 9.

  In step S6, it waits for a function response from another terminal device T2 to be received, and when a function response is received, in step S7, a directory request command designating a preset directory is transmitted from the wireless communication unit 9. To do.

  In step S8, it waits until a directory response is received from the other terminal device T2, and when the wireless communication unit 9 receives the directory response from the other terminal device T2, in step S9, a file transfer start command is sent to the wireless communication unit. 9 transmits to the other terminal device T2 and simultaneously transmits the files such as images and documents stored in the designated directory of the auxiliary storage unit 7 via the wireless communication unit 9.

  In step S10, it waits until the transfer of all files in the directory of the auxiliary storage unit 7 is completed. When the transfer of all files is completed, in step S11, a file transfer end command is sent from the wireless communication unit 9 to another terminal device. Send to T2. Further, in step S12, the wireless communication unit 9 transmits a disconnection request command to another terminal device T2. In step S13, the process waits until a disconnection confirmation is received from another terminal device T2, and when it is received, the file transfer process is terminated.

  FIG. 4 is a flowchart showing an operation in which another terminal device T2 receives a file as a receiving side.

  First, in step S21, the other terminal device T2 waits for reception of the connection request command from the portable terminal device T1, and when receiving the connection request command, in step S22, the terminal that issued the connection request command is set in advance. To determine whether the terminal is connected, and whether to connect. In the case where the terminal is not set in advance, when resources such as a hard disk and a memory necessary for file transfer cannot be secured, or when a file cannot be received due to some failure in the terminal, in step S32, a connection rejection command Is sent to finish the process.

  When a connection request is made from a preset terminal, the process proceeds to step S23, a connection confirmation response is transmitted, and the process proceeds to step S24. In step S24, a function request command from the portable terminal device T1 is waited. When the function request command is received, the process proceeds to step S25, and a function response notifying the function of the terminal and the current situation is transmitted.

  Further, in step S26, the reception of the directory request command from the portable terminal device T1 is waited. When the directory request command is received, in step S27, the existence and attributes of the designated directory are checked, and the file can be received. Send information on a directory response.

  In step S28, reception of a file transfer command is awaited. When a file transfer start command is received, file reception is started and the file is written to the designated directory. In step S29, the process waits for reception of a file transfer end command indicating that transfer of all files has been completed. When this file transfer end command is received, the process proceeds to step S30. In step S30, a disconnection request command is received from the mobile terminal device T1. When this command is received, in step S31, a disconnection confirmation is transmitted, communication is disconnected, and the process ends.

  In step S26, when the directory request is received, if the designated directory does not exist, a new directory is created. In step S27, a directory response is transmitted, and thereafter, the same processing as described above is performed.

  In step S10, when the file transfer is completed, the directory in which the already transmitted files are stored is immediately deleted, the transmission history is left in the RAM 5 or the flash ROM 4, and thereafter, the same processing as described above is performed.

  In step S10, the end of the file transfer is waited. When the file transfer ends, the contents of the transmitted directory are moved to another directory designated in advance, and thereafter, the same processing as described above is performed.

  In step S7, the directory request command transmitted to the other terminal device T2 is designated and transmitted so as to notify the directory configuration of the other terminal device T2. Next, in step S8, the process waits until a directory response is received. When the directory response is received, directory information of another terminal device T2 in the directory response is displayed on the display unit 6, and an arbitrary directory is displayed from the key input unit 2. The user is instructed to input. This information is put on the file transfer start command transmitted in step S9, and the receiving side directory is designated. Thereafter, the same processing as described above is performed.

  In step S7, when a directory request is transmitted, the attributes of the file to be transmitted are checked, and a directory set in advance corresponding to the attribute of the file to be transmitted is designated. Thereafter, the same processing as described above is performed.

  In the above embodiment, a portable terminal having a wireless communication function is assumed, but the same processing as described above can be performed in wired communication which is other communication means.

  In the above embodiment, the command / response is exchanged between the mobile terminal device T1 and the other terminal device T2. Instead of the command / response, the command / response is described in a language such as XML. Processing may be performed according to the tag.

  According to the above description, the receiving-side directory can be specified in the transmitting-side terminal, and there is an effect that it is easy for the user to use. In addition, since the mobile terminal device automatically detects other terminal devices and transfers the file to the specified directory, if the necessary settings are prepared in advance, the file transfer can be performed without any operation by the user. There is an effect that automatic transfer of detecting a terminal automatically and performing file transfer is possible.

  In addition, even when a directory is not created in advance at the receiving terminal, it is possible to transfer a file, and there is an effect that the operation is less for the user.

  In addition, since the mobile terminal device on the transmission side deletes the file in the directory immediately after the file transfer, the file transfer process can be performed even in a mobile terminal device that does not run out of memory and has few resources such as memory. This can be performed continuously, and it is easy to handle for the user.

  In addition, since the transferred file is saved in another designated directory, the reliability can be further improved. For example, even if a failure occurs in the receiving terminal, it can be easily recovered. And has the effect of higher reliability.

  In addition, it is possible to grasp the status of the directory on the receiving side in real time, and the user can specify the directory for file transfer, so that the user can specify the operation according to the current status, which is flexible and easy to use Play.

In addition, since the directory on the receiving side can be changed in accordance with the file to be transferred, various data handled by the mobile terminal device can be transmitted to a different directory on the other terminal device, which is easy for the user to handle. For example, there is an effect that a still image and a moving image can be transferred to different directories.
