Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides storage and conversion communication in which control information and data information from a calling subscriber is stored once in a storage and conversion device provided at an exchange or center, and then the data is transmitted to a called subscriber. Regarding the method.

In the conventional storage/conversion communication system, control information such as service type and terminating subscriber information from the originating subscriber and data information are successively transferred and stored in the originating storage/conversion device.

Once the information transfer from the originating subscriber is complete, the originating storage and conversion device reads and analyzes the received terminating subscriber information.

As a result of the analysis, if the other party is a subscriber of another station, control information and data information are transferred between stations to the receiving side storage/conversion device.

When the transmitting storage and forwarding device identifies that the other party is within its own station, and when the receiving storage and forwarding device receives information from the transmitting side, the transmission speed and terminal constants stored in the storage and forwarding device are , the subscriber information with standard interfaces such as control procedures is compared with that of the called subscriber information.

If the verification is successful and the connection is possible, the called subscriber is called and the data information is transferred.

On the other hand, if the verification is not possible, or if the verification is successful but the connection is not possible, such as connection restrictions or terminal failure, the sending storage conversion device directly sends the data to the calling subscriber, or the receiving storage conversion device sends the data to the calling subscriber. The converter notifies the originating subscriber of the inability to communicate, and erases the stored data information.

In this way, in the past, data information was stored at the same time without knowing the type or status of the called subscriber, so the memory of the storage/conversion device was held invalid, or invalid connections or
This has the disadvantage that the number of transfer operations increases.

In order to eliminate these drawbacks, the present invention provides a storage and conversion device that receives incoming subscriber information and queries a device that stores the subscriber information before storing data information in the storage and conversion device on the originating side. This prevents memory from being held invalidly or invalid connection/transfer operations.

Embodiments of the storage and conversion communication system according to the present invention will be described in detail below with reference to the drawings.

When performing storage/conversion communication from subscriber 1 to subscriber 11, subscriber 1 first makes a call, accesses storage/conversion device 3 through subscriber line 2 (dedicated line or switched line), and performs broadcast communication or priority communication. The service type and called subscriber information, that is, information on the subscriber 11, are sent.

The content of the called subscriber information is the called subscriber number, but the format of the information is not limited to the number itself, but may also be a mark, a symbolic code, or the like.

Then the operation of subscriber 1 or the switching center (not shown)
Through the processing, the originating subscriber information, that is, the information of subscriber 1 is sent to the storage/conversion device 3.

The storage/conversion device 3 stores the calling subscriber information in the control information storage section 4 together with the receiving subscriber information.

The outgoing and incoming subscriber information is retrieved and
3 to the information matching device 12.

The information collation device 12 is provided at one location in the country or for each region, and stores subscriber information for the entire country or for each region.

Subscriber information is the subscriber number with standard interface,
These include the contents of the standard interface for each subscriber, subscriber status, etc.

The content of the standard interface is information such as transmission speed, terminal constants, control procedures, etc., and there may be several types of standards, not necessarily a single type.

The subscriber status indicates whether the subscriber is able to communicate normally or is unable to communicate due to connection restrictions, terminal failure, or the like.

The information collation device 12 uses pre-stored subscriber information and
It is compared with the called subscriber information sent from the storage/conversion device 3.

If the specified terminating subscriber is registered, that is, has a standard interface, and is in a state where communication is possible, the communication permission signal and the interface contents of the originating and terminating subscriber are transmitted to the originating side via the trunk line 13. It is returned to the storage conversion device 3.

On the other hand, if the specified called subscriber is not registered, or if it is in a state where communication is not possible even if it is registered, a communication disallowance signal and its reason are sent back to the storage/conversion device 3 via the trunk line 13.

When the storage/conversion device 3 receives the communication permission signal, it instructs the originating subscriber 1 to send data information;
The sent data information is stored in the data information storage section 5 of the storage conversion device 3.

When data information storage is completed, it is compared with the interface contents of the calling and receiving subscriber received from the information matching device 12, and if the type is the same, the data information format is used as is, and if the type is different, the data information is converted. The received subscriber information is then transferred to the storage/conversion device 7 via the trunk line 6, and then transmitted to the subscriber 11.

On the other hand, when the storage/conversion device 3 receives a communication disallowance signal, it notifies the originating subscriber 1 that communication is not possible and the reason thereof, and disconnects the communication.

A control information storage section 8 and a data storage section 9 are provided within the storage conversion device 7.

FIG. 2 shows a second embodiment of the present invention, in which parts corresponding to those in FIG. It will be done.

When the storage/conversion device 3 stores the originating subscriber information and the called subscriber information in the control information storage section 4, it transfers the information to the information matching section 15 within the device for matching.

The information matching section 15 identifies whether the incoming call is a subscriber within its own station or a subscriber in another station from the incoming subscriber information.

In the case of a subscriber within the own station, the presence/absence of registration, the contents of the interface, the subscriber status, etc. are verified in more detail, and communication is permitted or not permitted in the same manner as described above.

On the other hand, in the case of a subscriber to another station, the station in which the subscriber is accommodated is identified, and the incoming subscriber information is transmitted from the storage/conversion device 3 to the identified station (storage/conversion device 7) via the trunk line 6. is transferred to the information matching section 16 in the storage/conversion device 7 for matching.

As explained above, according to the present invention, the incoming subscriber information is received before the data information is stored in the originating side storage/conversion device, and the incoming subscriber information is transferred to the device that stores the subscriber information. Since it is possible to know the user status, there is an advantage that it is possible to prevent invalidation of the memory of the storage/conversion device and invalidation of connection/transfer operations.
