Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a broadcast type information service system that transmits information (signals) with the same content to a plurality of subscriber terminals.

Various information services are provided to specific members for a fee or free of charge.

Information services are usually provided by mail or telephone, but information that requires quick reporting, such as stock information and commodity price information, is often provided by telephone. Telephone communications provide breaking news and, unlike broadcasting, are confidential as they are provided only to members. For example, securities company counters or salespeople provide information services over the telephone only to members who are loyal customers. ing. However, providing information services by telephone as described above has the disadvantage that it is difficult to provide such services to a large number of members at once. In other words, the method of calling members individually and providing information requires a considerable amount of time per member, and requires the information provider to prepare a large number of telephone terminals and lines, which is extremely expensive. It will be a great service. It is also possible to consider a broadcast system in which all subscriber terminals to which information should be provided are called at the same time and the information is provided at the same time, but in this case, all the member terminal transmission lines receiving the information are connected in parallel. Therefore, the capacity of the Koji Seiki machine closest to the information provider is limited, and it is not possible to provide information to a very large number of members. Furthermore, when calling a member terminal through several stages of exchange as shown in Figure 1, the subscriber number (address) of the member to be called must also be transmitted at the same time.
This poses problems both in terms of time and the efficiency of using the transmission path. In the present invention, the time required to complete information provision is small;
To provide a broadcast type information service system with high line usage efficiency.

The outline of the present invention will be explained below.

The present invention is based on the fact that in an information service system, member terminals receiving information provision can be registered in advance, and there is no major change each time information provision is made. In the system of the present invention, each exchange stores in advance the subscriber terminal numbers within the area covered by that exchange, and the information (signal) transmitted from the information provider is transmitted to all the subscriber terminals stored in the memory. to be transmitted. According to the system of the present invention, since the broadcasting function is distributed to the nearest exchange where each subscriber terminal is scattered, it is possible to provide services to a larger number of subscriber terminals than the conventional broadcasting system. In addition, since there is no need to transmit the subscriber terminal number, the transmission time is reduced by 4.0 mm, and line usage efficiency is also improved.

Further, since the transmission of the subscriber terminal number is not subject to bribery, it is advantageous for the line provider that the transmission of the subscriber terminal number is not necessary as in the present invention. The invention will be explained in detail below with reference to the drawings. FIG. 2 shows the exchange 1 used in the present invention. The exchange is an electronic exchange or a semi-electronic exchange with an electronic control section, and in addition to the functions of a normal telephone or data exchange, the following functions are added. That is, (1) A plurality of information response devices 2 and a plurality of address number memory devices 3 are provided corresponding to specific numbers such as 0001 to 001 flea.

It is assumed that these devices operate under the control of a central control device (marker) 4 of the exchange. ■ Outgoing register 5,
The marker 4 has a control function, which will be explained later in a separate section, in addition to the functions in a normal exchange.

■ Furthermore, the exchange 1 has an outgoing line link frame 6, a receiving line link frame 7, an outside line trunk 8, and an in-office trunk 9, which have the same functions as those in a normal exchange, and also connects multiple subscriber terminals at the same time. An ADDON trunk 10 that can be used is provided.

■ The marker control functions are as follows.

a. When the calling subscriber's calling dial signal is the said specific number, the marker connects the calling subscriber to the information response device 2 corresponding to said number and causes the information from the caller to be stored in the response device.

b Next, the marker extracts the subscriber terminal number stored in the address number memory device 3 corresponding to the specific number, and thereby connects the extracted plural subscriber terminal lines to the ADDON trunk via the contact point of the receiving link frame 7. Connect to 10.

c When the transmission from the originating subscriber is completed, the marker 4 disconnects the originating subscriber from the information response device 2, and connects the ADD/ON trunk 10 via the contact point of the originating line link frame 6.
The information response device 2 is connected to the originating side of the .

d) Then, the marker causes the information response device to send out the stored information and sends the same signal to all the extracted subscriber terminals.

e When the transmission of the stored information of the information response device is completed, the marker 4 releases the sending and receiving sides of the ADDON trunk, restores the status, and enters the standby state.

Note that the information response device 2 and address number memory device 3 in the above-mentioned basic exchange can be constructed from a magnetic drum, a magnetic disk, a semiconductor memory, or the like.

In this way, if a magnetic track or memory address or the like is determined corresponding to each specific number, one device can correspond to a large number of specific numbers. Although this exchange is more expensive than a conventional exchange due to its various additional functions, it is ultimately advantageous because it is located on the exchange side and is shared by a large number of subscribers. When there is a change in the number of members receiving information services, it is necessary to rewrite the subscriber terminal number stored in the address number memory in the above-mentioned exchange, but this can be easily done using the common technique.

For example, a signal may be sent to the exchange by pressing the function button and numeric button of a touch-tone phone currently in use, and rewriting may be performed by controlling the marker. This type of memory writing and rewriting technology is called “speed dial.”
It has already been put into practical use in "answering services" and "forwarding services." FIG. 3 is a system diagram of an embodiment of the present invention.
IB is shown.

Note that the address number memory device 3 of the exchange not only contains the subscriber terminal number in the target station, but also a specific number n, which specifies the corresponding information response device and address number memo IJ device of the adjacent pond station exchange≠sardine machine. , n2, ratio, ... are stored. Now, if information provider S sends a message, the above ■～■
By the function of the exchange described in 2 and the marker 4 described in 2, a broadcast communication is simultaneously made to multiple subscriber terminals R in the exchange IA, and at the same time, a specific number ratio is sent to the exchange IB of the pond office. A specific number n, , is sent to an exchange (not shown).

The same thing is done at the exchange IB and the not-shown exchange, and broadcast communication is carried out to a very large number of terminals via a plurality of exchanges.

That is, as described above, according to the system of the present invention, as the number of exchanges increases from the first to the second exchange, the number of subscriber terminals that can provide the same service increases dramatically. Broadcast service can be provided to subscriber terminals. Furthermore, since the broadcasting function is distributed evenly to each exchange, there is no risk of placing an excessive burden on only the exchanges closest to the information provider, such as a subordinate switch. Furthermore, since only necessary information is transmitted between each budget machine, and there is no need to transmit subscriber terminal numbers, the usage time of the line is short and its usage efficiency is improved. Note that the system of the present invention can be used for any of voice information (telephone), data communication, and facsimile communication.

In particular, computer-controlled services that automatically provide the latest information at regular intervals, data communication services,
It is most suitable for use where there is a relatively large number of one-way communications from an information provider to a subscriber, such as in facsimile communication services. Furthermore, although the exchange shown in Fig. 2 is configured to broadcast all at once to the subscriber terminals stored in the address number memory device, it is also possible to connect each subscriber individually and configure the system to broadcast sequentially. can. In this case, the information response device may be connected to the originating side of the intra-office trunk, and the subscriber terminal line may be connected to the receiving side, as in normal switching operations. Furthermore, the present invention can be configured as a system including only one cross-sectional machine as shown in FIG.

Furthermore, in the above embodiments, various functions are added to the exchange, but if it is difficult to add such functions to an existing exchange, an information response device, an address number memory device, and a marker can be added instead of an information response device, an address number memory device, and a marker. By installing a response device integrated with a control device as an additional device and assigning a specific dial number in the same way as a subscriber terminal, the same information provision as in the previous embodiment can be achieved.
