Description

[Detailed description of the invention] [Table of contents] Overview Industrial field of application Prior art (Figures 4 and 5) Problems to be solved by the invention Means for solving the problems (Figure 1) Effects Embodiments (Figures 2 and 3) Effects of the invention [Summary] The present invention enables a recorder connected to one subscriber line to send messages recorded on the recorder to multiple subscribers. In order to achieve this, multiple connections are made when the called party is a subscriber to an information broadcasting service.

[Industrial application field]

The present invention relates to an information broadcasting service system using a telephone line, and more particularly to one in which recorded messages can be multiplex broadcasted to a plurality of subscribers at the same time.

BACKGROUND ART Circulation services, which are a form of telephone exchange service, are widely used based on social demands. However, since telephone switching equipment is originally configured to connect a caller and a called party on a one-to-one basis, broadcast services are executed through complex switching control. Therefore, it is desired to realize a broadcast service that has a simple configuration and is flexible.

[Conventional technology]

When multiplexing a pre-recorded message,
Conventionally, two methods have been used, for example, as shown in FIG. 4 (al, mountain).

The system shown in FIG. , B-, etc. to a telephone number that is not in use at that time, if the exchange 20 detects that the telephone number is unused, this external subscriber A-...・Recorder 21
Connect to a channel that has a semi-permanent connection, for example, ``The phone number you are calling is currently not in use. Please check the phone number. ” will be broadcast. In this case, the recorder 21 is constantly driven endlessly. In addition, in Figure 4 (al), 22 is the line concentrator, 23 is the exchange of another station, 2
4 is a line concentrator.

In addition, in the method shown in Figure 4, a recorder 31 is installed on the subscriber side.
A line is connected to the exchange 30 through multiple channels.
Connect via concentrator 32. This recorder 3
In step 1, record weather forecasts, sports information, etc.
Also keep it running all the time. Therefore, when other subscribers A, B, C, etc. call this service to use the guidance service, multiplex broadcasting can be performed on the number of channels connected to the recorder.

[Problem that the invention seeks to solve]

However, in the system shown in FIG. 4 FAT, only the content recorded by the station can be broadcast, and subscribers cannot freely change the recorded content, which is inconvenient. On the other hand, when a subscriber uses a recorder to provide service information at a store, for example, 1.
If only the channel is connected to the central office side, as shown in FIG. 5, when there is a user first and the called party is busy, only a busy tone is transmitted and multiple connections cannot be made.

In addition, in the system shown in Figure 4, multiple channels are used with one telephone number (main telephone number), so these multiple channels are occupied at all times, resulting in degraded subscriber service. become.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an information broadcasting service that can simultaneously send messages from a subscriber side to a plurality of subscribers using one channel, in order to solve the above-mentioned problems.

[Means for solving problems]

In order to achieve the above object, in the present invention, as shown in FIG. 1, recorders 2 on the subscriber side are connected in multiple ways to an exchange 1 through a line concentrator 3 through only one line. Therefore, incoming calls from subscribers A, B, C---
When the exchange 1 determines that the connection is for the multiplexed recorder 2, these multiple subscribers A, B
, -.- can be connected to recording m2. Note 4.
5 is a line concentrator, 6 is another station's exchange, and 7 is a line concentrator.

[Effect]

In this way, the present invention not only allows a subscriber to simultaneously provide information to multiple other subscribers using only one line, but also allows the content of the recorded message to be easily changed. It is.

〔Example〕

An embodiment of the present invention will be described based on FIGS. 2 and 3.

FIG. 2 is a configuration diagram of an embodiment of the present invention, and FIG. 3 is an explanatory diagram of its operation.

In the figure, the same reference numerals as on the map indicate the same parts, 10 is a space switch, 11 and 12 are time switches,
13 is a central control unit; 14 is a subscriber category table in which information broadcasting service subscribers are listed; 1;
Reference numeral 5 is a subscriber status table which describes whether the destination is in an idle state or a busy state. Reference numerals 16 to 18 are control memories, which control the time switch 11, space switch 10, and time switch 12, respectively. The control data for this purpose is entered.

In the present invention, first, it is registered in the subscriber category table 14 that the subscriber of the recorder 2 is an information broadcasting service subscriber, and when there is an incoming call to this information broadcasting service subscriber, the first Even if there is an incoming call in a so-called busy state, subsequent calls are multiple-connected as follows.

That is, first, when there is an incoming call from subscriber A to the subscriber of recorder 2, central control unit 13 connects time slot α of time switch 11 and line concentrator 3 to connect recorder 2 and The space switch 10 is controlled to be connected, and the time slot β of the time switch 12 and the line concentrator 4 are controlled to be connected to connect the space switch 10 to the subscriber. In this way, while subscriber A is connected to recorder 2 and is receiving messages from recorder 2,
When another subscriber B receives an incoming call to the subscriber of the recorder 2, the central controller 13 connects the time slot γ of the time switch 12 to the line concentrator 5, and connects the time slot γ of the time switch 12 to the line concentrator 5. is connected to the time slot α of the time switch 11. As a result, 8
The time slot α is not only the time slot β but also the time slot T
Messages from the recorder 2 can be transmitted to both subscribers A and B. In this way, by multiplexing the time slots of the time switch 12 to the time switch 11 via the space switch IO, messages from the recorder 2 can be output to a plurality of subscribers.

Next, the operation of the present invention shown in FIG. 2 will be explained according to the flowchart shown in FIG.

(2) When subscriber B makes a call to recorder 2, central control unit 13 detects this via time slot T. Then, the subscriber status table 15 is read to check whether the called party is busy or not. If it is not busy, normal call processing is performed and the called party and caller are connected as usual.

■ However, if the called party is busy, the central control unit 13
checks the subscriber category table 14 to find out whether the called party is an information broadcasting service subscriber. If the user is not a subscriber to the information broadcasting service, a busy tone is output. However, if the user is a subscriber to an information broadcasting service, multiple connection processing is performed as described above, that is, time slot γ and time slot α are connected by the space switch 10. This causes time slot α to be already spaced.
Even when connected to time slot β by switch 10, time slot α is further connected to time slot γ.
Will be connected to the recording! 112 messages will be transmitted to both subscriber A and subscriber B.

In the above description, the exchange 1 is of the TST type, but the present invention is of course not limited to this, and as long as it is capable of multiple connections, for example, the TST type, the TS type, etc.
Other types such as ST type and TSSTSST type can also be used.

〔Effect of the invention〕

According to the present invention, only one line needs to be used on the message sending side, so there is no need to occupy multiple channels.
Messages can be sent to multiple subscribers simultaneously when necessary. Furthermore, since this message sending means, such as a recorder, is housed in the exchange through the subscriber line interface, it is possible to easily change the recorded message by installing the recorder in the house, and to store sales information at stores, etc. It becomes possible to easily send messages that meet the needs of subscribers at all times.
