Step (203) judging whether to receive the connection establishment response of the file receiver? If so, then continue to next step (204), if not, then get back to step (201) to request again;

Step (204) establishes a connection with the file receiver, and at the same time, the personal computer 12 of the file sender starts to transmit the file, and then ends the connection processing procedure.

Again, when step (203) waits for the file receiver to respond, a time-out control (time-out control) can be set, and if the time is up, the user can be allowed to choose whether to continue waiting or directly cut off and then resend the establishment request.

See also shown in Fig. 1, 3, it is the processing step that the personal computer 22 of the file recipient establishes a connection with the personal computer 12 of the file sender:

Step (301) first, the low-power mobile phone terminal 20 of the file receiver receives the connection establishment request sent by the low-power mobile phone terminal 10 of the file sender;

Step (302) sends a connection response to the low-power mobile phone terminal 10 of the file sender, and notifies the personal computer 22 of the file receiver to establish a connection;

Step (303) The personal computer 22 of the file recipient starts to receive the transmitted file, and then ends the connection processing procedure.

Again, when step (302) sends the connection response to the low-power mobile phone terminal 10 of the file sender, it can be set to an automatic answer mode, or it can be set to a wait to receive an order from the personal computer 22 of the file receiver, such as: manual answer mode, and connection requests can be rejected in manual mode.

In the present invention, in order to improve the reliability of file transfer, some necessary retransmission control can be performed on the file transfer process, as shown in Figure 4, the processing steps are as follows:

Step (401) first, the personal computer 12 of the file sender sends the file data to be sent to its low-power mobile phone terminal 10;

Step (402) This low-power mobile phone terminal 10 packs the file data received from the personal computer 12 of the file sender into packets, and sends it to the low-power mobile phone terminal 20 of the file receiver through the wireless channel interface 11, and the data can be Encapsulated into the third layer RT message of PHS protocol (PHS Radio Frequency Transmission management) and sent through the fast association control channel (FACCH);

Step (403) judging whether the confirmation of the file receiver has been received? If so, then continue to the next step (404), if not, then get back to step (401) to retransmit the file data;

Step (404) sends the next set of file data, and then ends the processing procedure of this file transfer.

Again, when waiting for the confirmation of the file receiver in step (403), a time-out control (time-out control) can be set, and if the time is up, the file data can be retransmitted from step (401).

Furthermore, please refer to shown in Fig. 1, 5, be that the personal computer 12 of this file sender sends the processing step of disconnection to its low-power mobile phone 10 terminal:

Step (501) First, the personal computer 12 of the file sender sends a cut-off request to its low-power mobile phone terminal 10;

Step (502) The low-power mobile phone terminal 10 sends a cut-off request to the low-power mobile phone terminal 20 of the file receiver through the wireless channel interface 11;

Step (503) the connection process ends, and the low-power mobile phone terminal 20 of the file receiver indicates that the disconnection is completed to the personal computer 22 of the file receiver, and ends the connection program.

The above description is only the best specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, any changes or modifications that can be easily conceived by anyone familiar with the technical field within the field of the present invention, All should be covered by the scope of the patent application in the following case.
