Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for preventing messages stored on the network side from being erroneously delivered to other recipients in a switching network, particularly in a store-and-forward network that has an automatic call reception function and stores messages. The present invention relates to a message storage and exchange system that prevents this from occurring.

Traditionally, when forwarding messages using the telephone network,
When connecting to the called subscriber using the telephone switching network function and confirming the other person directly, or when connecting to the called terminal using the automatic call receiving function, the subscriber identification number sent from the called terminal side is used. By confirming the recipient before forwarding the message, messages were prevented from being sent incorrectly.

This is based on the premise that the terminating subscriber number managed by the terminating connection side (network side) is correct, but if the terminating subscriber number itself has been changed within the network, However, if this changed destination subscriber exists, there is a drawback that the message may be mistakenly delivered to a different subscriber than the one to which the originating subscriber intended to send.

In order to solve the above-mentioned drawbacks of the conventional example, the present invention provides a switching network that has an automatic call receiving function and stores and exchanges messages, and the present invention has been developed to solve the problem of message errors that occur when the called subscriber number is changed within the network. The purpose is to provide a new message storage and forwarding method that prevents delivery.

Hereinafter, embodiments will be described in detail with reference to the drawings.

Next, the operation of this embodiment will be explained.

This embodiment is aimed at a facsimile storage and conversion network. First, when calling subscriber A wants to send a message to called subscriber B, one person dials a special number using a push-button telephone, and then the subscriber line The exchange 4A is in contact with a facsimile communication exchange 5A.

This facsimile communication exchange 5A uses a calling information detection device 7A to send out a special dial tone requesting a service type number and a called subscriber number, detects these calling information input from the calling subscriber A, and detects the calling information. is stored in the outgoing information storage device 8A, and this information is stored in the outgoing information storage device 11B of the facsimile communication exchange 5B on the receiving side via the outgoing information transmission/reception control devices 14A and 14B.

Further, the transmission information stored in the transmission information storage device 8A is further stored in the transmission information storage device of the facsimile storage and conversion device 6A via the transmission and reception control devices 12A and 13A.

On the other hand, for messages from the calling subscriber, the calling information detection device 7A sends out a special dial tone to instruct the calling subscriber to switch to two facsimile terminals, and the calling subscriber's switching device 3A is activated. After switching, the facsimile information from the two facsimile terminals is received by the facsimile information transmitting/receiving device 15A of the facsimile storage and conversion device 6A, and is stored in the facsimile information storage file memo 1J1.
Accumulates to 6A.

The outgoing information and facsimile information stored in the outgoing information storage device 9A and the facsimile information storage file memo 1J16A are sent to the outgoing information storage device 10 of the relay storage and conversion device 21 via the outgoing information and facsimile information transmission/reception control devices 18A and 19. , and stored in the facsimile information storage device 17.

Further, this information is stored in the outgoing information storage device 9B and the facsimile information storage file memo 1J16B of the facsimile storage and conversion device 6B on the destination side via the outgoing information and facsimile information transmission/reception control devices 19 and 18B.

Here, the destination facsimile storage and conversion device 6B stores the outgoing information in the outgoing information storage file 8B of the facsimile communication exchange 5B via the outgoing information transmission/reception control devices 13B and 12B, and establishes a connection with the called subscriber. request.

Here, the outgoing information comparison device 20B of the facsimile communication exchange 5B compares the outgoing information stored in the outgoing information storage device 8B with the outgoing information stored in the outgoing information storage device 11B, that is, the facsimile storage and conversion device The outgoing information received via the facsimile communication exchange is compared with the reserved outgoing information transferred directly from the facsimile exchange.
Only when the called subscriber numbers completely match, the calling information detection device 7B sends a connection instruction to the called terminal to the subscriber line exchange 4B, and if the called subscriber B is not busy, it connects to the facsimile terminal 2B. Make automatic incoming connections.

After that, the facsimile information storage file memory 16B
The facsimile information stored in is directly output from the facsimile information transmission/reception control device 15B to the facsimile terminal 2B, thereby completing the transfer of the message.

As described above, the outgoing information received by the outgoing facsimile communication exchange side is stored in the outgoing information storage device 8A, outgoing information transmission/reception control devices 12A and 13A, outgoing information storage device 9A, and the outgoing information storage device 9A.
Outgoing information and facsimile information transmission and reception control device 19, outgoing information storage device 10, outgoing information and facsimile information transmission and reception control device 19.18B, outgoing information storage device 9B, outgoing information transmission and reception control devices 13B and 12B, outgoing information storage device 8B, Outgoing information storage devices 8A, 14A.

14B and 11B, and the incoming call is connected after the incoming call information comparison device 20B checks the match of the incoming subscriber number, so changes within the network of the incoming subscriber number received from the calling party are performed. Dogs are effective in preventing incorrect delivery of messages.

As explained above, according to the present invention, in a message store-and-forward system having an automatic call reception function, the calling information inputted by the calling subscriber is divided into two routes and transferred to the receiving side equipment, and when connecting with the called subscriber. By confirming that the calling information from both routes matches before connecting, there is the advantage of preventing incorrect delivery of messages due to changes in the called subscriber's number within the network. If this check is combined with a callee ID check at the time of incoming call connection, it will be possible to completely prevent erroneous delivery of messages in the message store-and-forward system, and the practical effect will be very significant.
