本発明は、蓄積交換システムにおいて、蓄積交
換網を通して端末間で送受されるメツセージの親
展通信方式に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a confidential communication method for messages sent and received between terminals through a store and forward network in a store and forward system.
従来の親展通信方式は、一例として、ノードに
収容される端末が１または２以上の親展宛先を持

端末に親展通信文の着信表示のみを行わしめると
いうものであつた。 In the conventional confidential communication method, for example, when a terminal accommodated in a node has one or more confidential destinations, and a message to one of the confidential destinations arrives at the node accommodating that terminal, the message is first sent to the node that accommodates the terminal. The idea was to only display an incoming confidential message on the terminal.
この従来方式においては、２以上の親展宛先を

た。 In this conventional method, when there are two or more confidential destinations, it is unknown which destination the call is arriving at, so unless you perform the extraction operation for all confidential messages for each confidential destination one after another, the desired message cannot be retrieved. I was unable to retrieve confidential communications, which was inconvenient.
本発明の目的は、上記した従来技術の欠点をな
くし、親展通信文の取出し操作を容易にすること
ができる親展通信方式を提供することにある。 SUMMARY OF THE INVENTION An object of the present invention is to provide a confidential communication method that eliminates the drawbacks of the prior art described above and facilitates the operation of retrieving confidential messages.

ようにした親展通信方式にある。 The feature of the present invention is that when a node of the store-and-forward network receives a confidential message addressed to its accommodating terminal, first,
Sends only the confidential communication destination information to the terminal,
This is displayed on the terminal, and then the terminal sends a confidential message transmission request signal to the node by inputting the confidential message reception operation in this,
This is a confidential communication method that allows messages related to the confidential communication to be sent.

送信文データに付加されて蓄積交換機２Ａへ送出
される。 First, the operation of sending and receiving a confidential message will be explained. In the sending terminal 4A, the logical terminal number related to the desired confidential communication partner is set in the destination number generation section 5c, so this is sent from the transmission control section 5b as the destination address and is read by the transmission message reading section 5a. It is added to the sentence data and sent to the storage/exchange device 2A.
蓄積交換機２Ａは、これを受信して記憶装置３
Ａに蓄積するとともに、その宛先アドレスに基づ

Based on the received destination address, confidential communication destination information ADR-B is stored in terminal 4B.
Send CIR.
この親展通信宛先情報ADR−CIRには、通常
のアドレス信号ADRに親展宛先コードCIRが付
加されており、端末４Ｂでは、これを受信する
と、受信制御部６ａが親展通信の着信であること
を識別し、更に親展宛先表示部６ｂへ送出する。 This confidential communication destination information ADR-CIR has a confidential destination code CIR added to the normal address signal ADR, and when the terminal 4B receives this, the reception control unit 6a identifies the incoming confidential communication. Then, it is further sent to the confidential destination display section 6b.

展宛先コードCIRに対応する親展文受信宛先表示
コードRDCを発生せしめ、これを出力表示する。 The confidential destination display unit 6b activates the confidential destination registration register 6c and adds the confidential communication destination information ADR-
The CIR is sent and compared with the registered contents, a confidential message receiving destination display code RDC corresponding to the confidential destination code CIR is generated, and this is output and displayed.
また、その出力表示終了後、受信制御部６ａを
介し、応答信号RSPを蓄積交換機２Ｂへ送出す
る。 Further, after the output display is completed, the response signal RSP is sent to the storage/exchange device 2B via the reception control section 6a.
以上の動作は、異なる親展宛先に対して複数の
親展通信が連続して着信しているときは、各親展
宛先ごとに順次に連続して同様に行われ、それぞ
れ、その出力表示が行われる。 When a plurality of confidential communications are successively received for different confidential destinations, the above operations are performed in the same way for each confidential destination one after another, and the respective outputs are displayed.
親展宛先表示部６ｂにおける親展文受信宛先表
示により、親展文受信操作入力部６ｄを操作する
と、親展文送信要求信号REQ−CIRが受信制御
部６ａを介し、蓄積交換機２Ｂへ送出される。 When the confidential message reception operation input section 6d is operated based on the confidential message reception destination display on the confidential destination display section 6b, a confidential message transmission request signal REQ-CIR is sent to the storage/exchange device 2B via the reception control section 6a.
なお、この親展文受信操作は、キーまたは暗証
番号等により、通常、親展宛先に係る特定人のみ
が行いうるようにしてある。 Note that this operation of receiving a confidential message is normally made possible only by a specific person related to the confidential destination using a key or password.
これにより、蓄積交換機２Ｂは、転送識別信号
Ｉを端末４Ｂへ送出する。 Thereby, the storage/exchange device 2B sends the transfer identification signal I to the terminal 4B.
なお、この転送識別信号Ｉは、親展通信、通常
通信にかかわらず、蓄積交換機２Ｂから転送する
メツセージのシーケンス番号を通知するものであ

受信制御部６ａは、転送識別信号Ｉを受信する
と、シーケンスの正常性をチエツクし、正常の場
合、受信文出力部６ｅへ起動信号OPEを送出す
る。 Upon receiving the transfer identification signal I, the reception control section 6a checks the normality of the sequence, and if it is normal, sends an activation signal OPE to the received message output section 6e.
これにより、受信文出力部６ｅは、起動され、
その完了後、通信文受入準備完了を示す応答信号
RSP−Ａが受信制御部６ａを介し、蓄積交換機
２Ｂへ送出される。 As a result, the received sentence output unit 6e is activated,
After completion, a response signal indicating that the message is ready to be accepted.
RSP-A is sent to the storage/exchange device 2B via the reception control section 6a.
蓄積交換機２Ｂは、この応答信号RSP−Ａの
受信により、当該親展通信文に係るメツセージ
DATAを記憶装置３Ｂから読出し、順次、端末
４Ｂへ送出する。 Upon receiving this response signal RSP-A, the storage/exchange device 2B sends the message related to the confidential communication.
DATA is read from the storage device 3B and sequentially sent to the terminal 4B.
端末４Ｂは、受信制御部６ａの制御により、こ
