When the device 30 serves as a temporary storage device for exchanging files between external terminal devices (such as the wireless terminal device 332 or other terminal devices), the access path selecting unit 306 determines the access path according to the actual situation.

For example, if the built-in memory medium (such as the built-in memory unit 312 of the electrical connection access path selection unit 306) is provided in the device 30, the built-in memory medium can be used as a pre-transfer file between the external terminal devices. The temporary storage memory is provided, and the access path selection unit 306 directs the access path to the built-in memory unit 312.

The memory card 334 can also be used as a temporary storage memory when there is no built-in memory or after selection. In actual operation, when the memory card 334 is connected to the network temporary storage device 30 through the memory card access unit 308, the access path selecting unit 306 determines that the memory card 334 has been plugged according to the obtained electrical signal, and will The access signal transmitted by the control unit 301 is directed (via the access path selection unit 306) to the memory card access unit 308 to provide the terminal device with access to the contents of the memory card 334.

In another case, if the device is not plugged into the memory card 334 and there is no built-in memory unit 312, the access path selection unit 306 then determines through the external access unit 309 whether any external storage device 335 is connected to the device. 30.

If the memory card 334 is not connected to the device 30, the access path selection unit 306 will switch the access path to the path of the external storage device 335 that accesses the external access unit 309.

When the network temporary storage device of the file designation transfer function is used to execute the file transfer between the terminal devices, the implementation described in FIG. 4 may be referred to, in which the first device 41 is displayed, ready to be used therein. The file is transferred to another device, such as the second device 42.

The first device 41 is preferably connected to the network temporary storage device 40 by wireless communication, the main purpose of which is to request to be transmitted to the target device (such as the second device 42), and the second device 42 can also be connected to the wireless communication mode. The road temporary storage device 40 acquires the file of the first device 41. Before performing the file temporary storage operation, the network temporary storage device 40 should first prepare the type of the temporary storage memory, for example, using the built-in memory or the inserted memory card, or even After the external storage device is determined, the control unit determines the access path by the access path selection unit.

Before performing the file transfer operation, the first device 41 should complete a handshake with the network temporary storage device 40 to exchange connection information, and as shown in step 401, the first device 41 requests the connection network to be temporarily suspended. The storage device 40 issues a connection request to the device 40. After the step 402, the device 40 sends a signal confirming that the first device 41 can be connected. In this initial step, security can be ensured between the first device 41 and the network temporary storage device 40 through some verification procedures, such as the verification process of a general wireless network connection.

Then, as step 403, the first device 41 sends a transmission file to the device 40. After the request, in step 404, the network temporary storage device 40 prepares the temporary storage space and waits for the preparatory work, and responds to the first device 41 to confirm that the file can be transmitted. The first device 41 then begins to transmit the file, and the packet further contains various network messages, including the packet source, the target, the file itself and related information, as shown in step 405. Therefore, the network temporary storage device 40 can obtain the information of the file transfer target through the parsing packet, including the identification information of the target device, and store the specific memory in the device, such as the identification unit in the foregoing control unit.

The network temporary storage device 40 plays the role of file temporary storage in this process. Unlike the concept of the file storage device, the temporary storage device may be smaller than the file size, and the contents of the temporary storage device are also cleared when the file is transmitted. After the file transmitted by the temporary storage device 41 is completed or partially completed, the network temporary storage device 40 can receive a request for the other device to request the file.

In this example, another device requires the network temporary storage device 40 to request connection and access to the file. This creation introduces a transmission object identification technology. When a device is connected to the network temporary storage device 40, the network The path temporary storage device 40 will actively analyze the identification packet transmitted by the connection device to actively detect whether the target device is the target device, that is, the network temporary storage device 40 does not transmit the file to the device that is not the transmission target.

In step 406, the second device 42 issues a connection request to the network temporary storage device 40, and the security can be enhanced during the connection process by using the wireless network connection verification program. In this request packet, the identification data of the second device 42 is already carried in the packet, so that the network temporary storage device 40 can compare the target information contained in the file transmitted by the first device 41 in addition to confirming that the packet can be connected, and actively confirming The identity of the second device 42. In another embodiment, the network temporary storage device 40 can actively detect whether there is any radio in the range of the wireless signal. The wave device can actively detect the target device.

After the second device 42 is connected to the network temporary storage device 40, it is determined by the network temporary storage device 40 that if it is not the transmission target specified by the first device 41, the temporarily stored file is not actively transmitted to the second file. The device 42, the second device 42 can be rejected for connection, or can only use other functions of the network temporary storage device 40, such as the function of packet routing.

If the second device 42 subsequently issues an acknowledgment connection, it also confirms that the second device 42 is the target device. In step 407, after parsing, the network temporary storage device 40 confirms that the second device 42 is the target device to be delivered by the first device 41, and the network temporary storage device 40 can actively query the second device 42 whether to receive the message through the message. After the file from the first device 41 is confirmed to be transmitted, the network temporary storage device 40 transmits the temporary file to the second device 42, as in step 408. The network temporary storage device 40 achieves the purpose of transferring the file between the first device 41 and the second device 42 for the intermediate temporary storage device. While the file is being transferred, the network temporary storage device 40 may still acquire the file by the first device 41 at the same time, achieving the purpose of instant transmission. In the case of an embodiment, the second device 42 may choose whether to receive the transmitted file.

With the above-mentioned authoring technique, the trouble of directly transferring files between the first device 41 and the second device 42 can be eliminated, because the transmission of files between the two devices by using the wireless network is still limited by the transmission technology, software or bandwidth. Technical issues, this creation provides a purpose to perform the transfer without changing the settings and installing any software.
