JPS59122154A - Retrieval requesting system of facsimile picture information - Google Patents

Abstract

PURPOSE:To eliminate waste of operation by storing once the retrieval request when the retrieval is disabled temporarily and applying retrieval, thereafter. CONSTITUTION:When a junction line T tying areas A and B is blocked, a central processor of the area A and a facsimile picture information retrieval request receiver RRC are connected via an exchange network EXA. The RRC receives and stores retrieval request information. The RRC checks the idle state of a trunk TRKA periodically. When the TRKA is idle, the number of a facsimile storage device S/F is outputted from the RRC, and transmitted to a line exchange of the area B. When the retrieval request information from the RRC is received by the S/F, the normal processing is started. The operation repeating the retrieval request from a terminal is made unnecessary for avoiding useless repetition by the line exchange so as to reduce the load of the central processor.

When searching via a network, it may be possible that the search request cannot be made temporarily because this trunk line is in full use. Therefore, when such a situation is encountered, it is necessary to repeat the search request operation at all times when the trunk line is vacant, making it impossible to provide sufficient service.

Ａにて接続する。Next, the above-mentioned Bonkai CoFII! The structure and operation will be explained in detail with reference to FIGS. 1 and 2. Under the same conditions as above, when the CPU in its own area that accommodates kFAXA i recognizes that it is impossible to set up a communication path from FAXA to S/F, the CPU selects the RRC empty terminal and selects terminal 1. If n is empty, CPUA sends R via TKCA.
1' Instructs the trunk control interface section POT of the LC to receive the search request report along with the selected terminal number report.
oNext, connect CPUViFAXA and lH%c, and display connection completion indication to FAXA. Upon receiving this connection completion indication, fcFAXA sends the search requesting terminal number, S/F number, and search code to Etc based on the transmission procedure. Next to the RC is the transmission procedure control unit L.
The transmission procedure is controlled by the LC, and the search request information sent from the FAXA is transmitted to the test request transmission/reception control section RFC via the lines tltlJ control section LNC and LLC. This RFC specifies the received search request report? Memory part M
While storing it in EM, send a reception completion report 1L to FAXA.
via Lc and LNCi. Upon receiving the reception completion report, the FAXA confirms that the image information search request has been accepted, and disconnects the caller. The call disconnection is detected by the CPU via LCA2 and LCCA, and the CPU thereby disconnects the connection between FAXA and RRC. Next, the RFC of 1 RC will be sent to POT and KC after a certain period of time.
A trunk line selection request is made to CPUA via A'i. Upon receiving the trunk line selection request, the fCcPUA performs the selection operation, captures the empty trunk line, that is, the corresponding TRKA, and captures the SND, and performs 1EX between the TRKA and the SND.

ービス向上を図れる。As explained above, according to the present invention, a line switching device that accommodates a facsimile storage device is connected to this switching device via a trunk line, and a search request for facsimile image information stored in the facsimile storage device is successfully completed. In a facsimile communication system equipped with a line switching device that accommodates all facsimile terminals, one trunk line is completely blocked and all the connection terminals to the facsimile storage device are completely blocked! 71 When a call encounters a situation in which a facsimile image information search request from the terminal device is temporarily unavailable, the search request information is temporarily stored and later sent to the information facsimile storage device. It is possible to completely eliminate the need for repeated operations of search requests from the terminal device. Therefore, according to the present invention, it is possible to prevent the line switching device from needlessly repeating call processing that requires high-level real-time processing, and to reduce the load on the central processing unit. Furthermore, once a request for retrieval of facsimile image information is made, the same information retrieval is eventually accomplished regardless of the state of the system at that time, thereby improving the service.
