Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a system for notifying a broadcast number to the network when using a broadcast service, which is a type of store and forward service, in a network capable of providing a store and forward service.

FIG. 1 shows the connection relationship between terminals and storage and forwarding machines in a conventional store-and-forward service network. In FIG. 1, 1 is a calling side terminal, 2 is a storage exchange, and 3 is a called side terminal. In order to perform the broadcast service in this method, the calling terminal 1 sequentially dials the broadcast numbers of the plurality of receiving terminals 3 to be broadcast.
Information to be transferred (for example, image information in the case of a facsimile terminal) is transferred to the storage/exchange device 2, and the storage/exchange device 2 stores the broadcast number and the information to be transferred in a storage section (not shown). Next, when transferring the information from the storage/exchange device 2 to the receiving terminal 3,
A method is adopted in which the stored information is transferred by sequentially calling the called terminals using the stored broadcast numbers.

Furthermore, in this conventional method, there are two methods for the storage/exchange 2 to receive the broadcast number and to call the called terminal 3.

The first method will be explained with reference to FIG. In FIG. 2, 4 is a dial reception section, 5 is a broadcast number development section, 6 is a broadcast number storage section, and 7 is a dial transmission section, and the other symbols are the same as in FIG. Further, in the explanatory diagrams of the storage/exchange device 2 in the following description, only those necessary for explaining the functions according to the present invention are illustrated. First, the calling side terminal 1 sends broadcast numbers in the form of dial pulses to the storage/switching device 2 as many as the number of broadcast destinations of the receiving side terminal 3 to be broadcast. The received data is converted into a storage format and stored in the broadcast number storage section 5. In this case, when the transmitted broadcast number is an abbreviated number, the dial receiving unit 4 receives the dial pulse of the abbreviated number and converts it into a storage format, and then the abbreviated broadcast number is transferred to the broadcast number expansion unit 5. The data is expanded into an actual broadcast number and stored in the broadcast number storage section 6. Next, in order to call the called terminal 3, the broadcast number stored in the broadcast number storage section 6 is converted into a dial pulse by the dial transmission section 7 and sent to a line exchange (not shown). This is to set up a line with the receiving terminal 3. In this method, it is necessary to dial the number of broadcast numbers as many as the number of broadcast destinations from the calling terminal, which not only makes the input operation troublesome but also requires a dial reception section 4, which has the disadvantage of making the hardware expensive. Ta. Furthermore, when abbreviated numbers are used, there is a disadvantage that the processing load on the storage/exchange device 2 becomes heavy.

The second method is shown in FIG. Each reference numeral in FIG. 3 indicates the same thing as in FIG. 2. In this method, a broadcast number is sent from a calling terminal 1 in a data format (for example, a character, etc.) to a storage/exchange 2, and the storage/exchange 2 stores the broadcast number in a broadcast number storage unit 6, and the receiving terminal 3, in the same way as in the first method, the dial transmitter 7 converts the stored broadcast number into a dial pulse and sends it to the line exchange (not shown), and the called terminal Set up a line with 3. In this case, when the broadcast number sent is an abbreviated number, the broadcast number expansion section 5 expands the shortened broadcast number into an actual broadcast number in the same way as in the first method, and then the broadcast number is The data is stored in the storage unit 6.
In this method, the dial receiving section 4 is not required, and the drawbacks are improved compared to the first method, but when inputting broadcast numbers, the number of broadcast numbers sent is equal to the number of broadcast destinations. This has the disadvantage that input must be made from the side terminal 1, which makes the input operation cumbersome, and when an abbreviated number is used, the processing load on the storage/exchange device 2 becomes heavy.

The purpose of the present invention is to prevent the storage/exchange device 2 from existing in the conventional system.
It is unnecessary to provide a dial receiving section 4 for receiving broadcast numbers by dial pulses and a broadcast number expansion section 5 for expanding shortened broadcast numbers, thereby reducing the processing load on the storage and switching equipment. Furthermore, even if there are multiple broadcast destinations, they can be easily specified from the sending terminal 1, and will be described in detail below.

An embodiment of the present invention will be described using FIGS. 4 and 5. FIG. 4 shows the connection relationship between a terminal and a storage exchanger in an embodiment of the present invention, and 16 is an adapter according to the present invention, which is attached to a terminal and functions only when the terminal operates as a calling terminal. ,
Other numbers correspond to those in FIG.

FIG. 5 shows a detailed block diagram of the adapter 16 in FIG. 4, as well as a connection diagram between the adapter 16, the transmitting terminal 1, and the storage/exchange device 2, where 8 is a microprocessor (CPU) that controls the entire adapter 16, and 9 is a microprocessor (CPU) that controls the entire adapter 16. 10 is a read-only memory (ROM) that stores a control program; 10 is a random access memory (RAM) that stores a broadcast destination number;
11 is a dial sending unit, 15 is a key operation unit consisting of a plurality of destination keys, and 12 is a key operation unit 15.
I/O port (IOP) which is an interface part of the CPU 8, 13 is a frame synchronization transmitting and receiving circuit that transmits and receives data to and from the line, 14 is a modem, 17 is a switching relay provided in the adapter 16, 18 is a terminal control unit, Reference numeral 19 denotes a switching relay provided in the transmitting terminal 1, and the other numbers are the same as those in FIG. 3. In the block diagram of the adapter 16 in FIG. 5, thick lines indicate bus lines, thin lines indicate data lines, and dotted lines indicate control lines.

To operate this, as an initial state, the switching relay 17 in the adapter 16 is connected to the dial sending unit 11.
switching relay 19 in the transmitting terminal 1
Set to connect with adapter 16,
By pressing the destination key with one touch from the key operation unit 15, one abbreviated broadcast destination number is input. With this input, the key operation section 15 and
I/O port 12, which is the interface between CPU 8, generates an interrupt to CRU 8,
A control program corresponding to the interrupt stored in the ROM 9 operates to read into the CPU 8 the shortened format broadcast destination number input by the destination key. The RAM 10 stores a plurality of expanded actual destination numbers to be broadcast corresponding to shortened format broadcast destination numbers for each destination key, and the CPU
In step 8, a plurality of expanded actual destination numbers to be broadcast corresponding to the input short-format broadcast destination number are retrieved from the RAM 10 for later transmission.
It is temporarily stored in the temporary storage area of ROM10.

In order to call the receiving terminal 3 that should be broadcast next,
First, the storage/exchange device 2 that accommodates the called terminal 3 is called. The CPU 8 extracts from the ROM 10 the calling number of the storage/exchange 2 corresponding to the inputted broadcast destination number in the abbreviated format, and transfers it to the dial sending section 11. The dial sending unit 11 converts the calling number of the storage/exchange device 2 into a dial pulse, transfers it via the switching relay 17 and the switching relay 19, and a line with the storage/exchange device 2 is set up by a line switch (not shown). be done. Next, the switching relay 17 is switched to connect with the modem 14 in response to a response signal of the calling section returned from the called storage/exchange device 2, and is then temporarily stored in the temporary storage area of the ROM 10 based on a command from the CPU 8. The expanded broadcast number is transferred to the storage/exchange 2 in its data format (without being converted to a dial pulse) via the frame synchronization transmitting/receiving circuit 13, modem 14, switching relay 17, and switching relay 19. As described above, the storage/exchange device 2 only has the broadcast number storage section 6 and the dial sending section 7, and stores the transferred broadcast number in the data format in the broadcast number storage section 6. Upon completion of transmission and reception of the broadcast number between the adapter 16 and the storage/exchange device 2, the switching relay 19 in the calling terminal 1 is switched to connect with the terminal control unit 18, and image information, etc. (if it is a facsimile device, etc.)
data is transferred and stored in a storage section (not shown) of the storage/exchange device 2.

Next, when transferring the stored image information etc. from the storage/exchange device 2 to the receiving terminal 3, the broadcast number stored in the broadcast number storage section 6 is converted into a dial pulse by the dial sending section 7. After converting, the dial pulse is sent to a line exchange (not shown), and a line with the receiving terminal 3 is set up, the image information etc. stored in the storage section is transferred to the receiving terminal 3.

The adapter 16 is connected to all terminal devices as shown in FIG. adapter 1
It is disconnected from 6 and does not function.

As explained above, in this embodiment, the key operation section 1
From 5 onwards, just by pressing the destination key with one touch, it will be expanded to multiple destinations that should be broadcast according to the destination key.
Since multiple broadcast receiving terminals 3 can be called, there is no need to make multiple dials just for each destination when performing broadcast service, and multiple broadcast numbers are sent to the storage/exchange device 2 in the form of dial pulses. Since the information is transmitted in the form of data without any data, there is no need to provide a dial reception section in the storage/exchange device 2, and the cost of the system can be reduced.

Also, by providing the sending terminal 1 with the function of the broadcast number expanding unit 5, which was conventionally performed by the storage and exchange 2, the processing load on the storage and exchange 2 can be reduced and other third parties can be added. Become.

In the present invention, when performing a broadcast service in a store-and-forward network, the broadcast number development process is performed by the originating terminal 1, so the processing load on the store-and-forward device 2 can be reduced, and the service of the entire network can be improved. At the same time, a plurality of destination terminals 3 to be broadcast simultaneously can be called by pressing the destination key with a single touch, thereby reducing the operational burden.

As described above, the present invention has the following effects.

(a) Instead of dialing multiple destinations one by one,
Since the contents stored in the adapter's memory are sent out in data format using a modem, it can be sent out in a short time and there is less line holding at the calling terminal.

(b) Since broadcast destinations can be specified with a single touch operation of the broadcast destination key, operability is good and there are fewer operational errors.

(c) Since multiple called party numbers specified by the broadcast destination key are sent from the calling terminal in data format as the actual destination numbers, the storage and switching equipment does not require a dial reception section or a broadcast number expansion section. Therefore, costs and processing burden can be reduced.
