Abstract

SUMMARY OF THE INVENTION The essence of the invention is that through a switching system a bidirectional connection is established to receive signals. Between the subscriber and the end point, information signals with pauses are transmitted from the end point to the subscriber, received at the subscriber’s side and compared with the reference signal. When the information signal coincides with the reference signal, the acknowledgment signal is transmitted from the subscriber to the end point. after which, at the end point, the information signal is stored and a bi-directional signal transceiver connection is distinguished. 1 hp f-ly. 1 il.

Description

The invention relates to communication technology and can be used on country telephone networks.

The purpose of the invention is to expand the functionality of the method by providing the subscribers of the telephone network with the ability to quickly transfer information necessary for conducting sociological research and statistical accounting, while increasing the reliability of this information.

The drawing shows a structural diagram of the system that implements the method.

It contains a group of subscriber units 1 (one unit is depicted), which can be used as ordinary telephone sets, channel switching system 2, made in the form of an automatic telephone exchange (or group of stations) with the caller number transmission equipment (AON). and

end point 3. Subscriber installation 1 and end point 3 are connected to the system 2 by switching the channels by subscriber lines 4 and 5, respectively.

Terminal point 3 contains a microprocessor statistical accounting system 6, to which a receive signal receiver 7 is connected, a sender of 9 parcel number signals corresponding to the sequence number of the information signal transmitted from shaper 8 towards the subscriber, a call signal receiver 11, a request and receiving the caller's number (UZ-PI). The bidirectional input / output 13 of the switch 11 is connected to the subscriber line 5, the bi-directional output / input 14 of the switch 11 is connected to the input 15 emnika 7, 8 shaper output 16 and input / output devices 17, 18, 12. The output switch 11 is connected to input 19 priemni6

ka 10 call signal. Control input 20 of switch 11 is coupled to system 6.

The imaging device 8 information signals has an additional output 21, which is connected to the input 22 of the imaging unit 9 signals of the parcel number.

The essence of the method for transmitting and receiving information in a circuit switched system is as follows.

In the process of conducting sociological research, at the initiative of the subscriber through the switching system 2, a bidirectional signal-transmission connection is established between the subscriber 1 (subscriber unit 1) and terminal point 3. In point 3, the signal to the call from the system 2 is received at the receiver 10, transmit it into the microprocessor system 6, after which the microprocessor system 6 is applied to the switch 11 at its input 20. In the switch 11, the inputs / outputs 13 and 14 are connected.

After that, from end point 3 to subscriber 1, several informational messages are transmitted successively with pauses between them. This transmission is carried out from the imaging unit 8, forming, during the transmission of each information message in the imaging device 9, a signal of the parcel number, which corresponds to the sequence number of the message transmitted to the subscriber.

On the subscriber's side, 3 messages transmitted from the end point are received in succession and each of them is compared with a reference one.

In this method, under the reference messages, such messages are taken which, in the process of conducting sociological surveys, should be transmitted from the subscribers of the telephone network to the terminal point for their statistical accounting. At the same time, the set of messages transmitted from the end point to the subscriber should be composed so that each of the subscribers of the telephone network can select a message that he considers to be a reference one.

As an example, we can give an example of a sociological research on the evaluation by subscribers of the quality of a particular television program. In this case, the following messages can be successively transmitted to subscribers from the end point: the transmission is bad, the transmission is satisfactory, the transmission is good, the transmission is different, I refrain from evaluating the transmission.

The subscriber classifies one of these messages as a reference.

When the information message transmitted from the end point 3 matches the reference message, the information message is transmitted from subscriber 1 and the acknowledgment signal is received at end point 3, and the acknowledgment signal is transmitted from the subscriber as a release signal. The signal is received at receiver 7 and transmitted to

0 microprocessor system 6, in which, after receiving a signal, the state of the generator 9 of the number of the parcel number is read and stored.

Then from the microprocessor system

5 6 act on input 20 on switch 11 to return it to its original state by disconnecting the connection.

So in end point 3

0 collects data required for statistical records during the sociological survey period.

This method provides for increasing the reliability of statistical accounting and sociological research by protecting the research results from targeted actions of a group of subscribers. For the implementation of this protection is used installed on the telephone networks of the country

0 equipment Caller ID (AON). When a bidirectional connection is established, after receiving by the receiver 10 a call signal and affecting switch 11 and before

5, the transmission from the subscriber of the said confirmation signal, from the microprocessor system 6, affects the device 12 for requesting and receiving the caller's number (SPIR). From UZPI 12 transmit in

0 side of the caller the request signal of the subscriber number, the number of the caller is transmitted from the automatic telephone exchange, which includes the caller, and then

The 5 numbers received at the SPI 12 are transmitted to the microprocessor system 6. In the microprocessor system 6 of the end point 3, the caller number signals are compared with the previously received signals.

0 numbers of subscribers who have already taken part in sociological surveys, and the mentioned signal storing of the number of the parcel corresponding to the reference message is carried out in case of a mismatch

5 compared signals of subscriber numbers, and the signal of the sending number is memorized together with the signal of the calling subscriber number.

Thus, repeated or multiple connection establishment from subscribers to end point 3 does not change the results of statistical accounting.
