Abstract

PURPOSE:To eliminate the need for exceptional processing which is performed when a receiving file area is exceeded on a reception side by returning the capacity of the receivable file free area on a reception side in response to an inquiry about the file free area from a transmission side and sending only a receivable amount of data on the transmission side. CONSTITUTION:A transmission-side free area inquiry part 13 inquires the receivable file free area of the reception side before file transfer from a transmission data part 12. A reception-side transmission/reception part 21 once receiving this inquiry sends this inquiry to a free area answer part 23. A file free area control part 14 monitors the free area for a received file 22 at all times and counts its capacity, so a free area correspondence part 23 knows the capacity of the free area from the file free area control part 24 on receiving the inquiry and returns the capacity of the free area to the transmission side through the transmission/reception part 21. Consequently, data are prevented from being sent exceeding the reception-side file area and the need for exceptional processing is eliminated.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明はファイル転送処理方式、特に情報処理システム
において通信回線を利用したファイル転送処理方式に関
する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a file transfer processing method, and particularly to a file transfer processing method using a communication line in an information processing system.

〔従来の技術〕[Conventional technology]

従来、この種のファイル転送処理方式は、受信側におけ
る受信用のファイル空き領域の容量に関係なくデータ伝
送を行ない、受信側のファイル領域を超えたデータ伝送
か発生した場合に、送信側と受信側とは共にファイル領
域を超えたことによる例外処理を行なっている。Conventionally, this type of file transfer processing method performs data transmission regardless of the amount of free file space available for reception on the receiving side, and when data transmission exceeds the receiving side's file area, communication between the sending side and the receiving side occurs. On both sides, exception processing is performed due to exceeding the file area.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

上述した従来のファイル転送処理方式は、ファイル領域

側とで例外処理を行なうが、処理が複雑で、かつ多くの
処理時間を要するという欠点がある。In the conventional file transfer processing method described above, when data transmission/reception that exceeds the file area occurs, exception processing is performed on the sending and receiving sides, but the drawback is that the processing is complex and requires a lot of processing time. There is.

構成される。The file transfer processing method of the present invention is a file transfer processing method using a communication line, and includes a free space inquiry means for checking file free space from a sending side to a receiving side, and a free space inquiry means that receives an inquiry by the free space inquiry means. a free space response means for notifying file free space from the receiving side;
The present invention is configured by having a file free area management means that can constantly monitor and report the file free area for reception on the receiving side.

〔実施例〕〔Example〕

次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

。FIG. 1 is a block diagram of one embodiment of the present invention. The embodiment shown in FIG. The transmission data section 12, the free space inquiry section 13, and the receiving side transmitting/receiving section 21. Received file 22. It is composed of a free space response section 23, a file free space management section 24, and a communication line 10 that connects the transmitting/receiving section 11 on the transmitting side and the transmitting/receiving section 21 on the receiving side.

信側へ空き領域の容量を返答する。In the above configuration, the free space inquiry unit 13 on the sending side inquires of the receiving side about the free space capacity of the receivable file prior to file transfer from the sending data unit 12. When receiving this inquiry, the transmitting/receiving unit 21 on the receiving side transmits this inquiry to the free space response unit 23. Since the file free space management section 24 constantly monitors the free space of the received file 22 and counts its capacity, when the free space response section 23 receives an inquiry, the file free space management section 24
4, the capacity of the free area is known, and the capacity of the free area is returned to the transmitting side via the transmitting/receiving section 21.

果がある。As explained above, in the present invention, in response to a file free space inquiry from the sending side, the receiving side replies with the amount of free space of the file that can be received, so the sending side only sends the amount of data that can be received. This has the effect of eliminating the need for exception handling when the receiving file area is exceeded on the receiving side.
