Description

Method and device for telephoning with a selectable telephone tariff

The invention relates to a method and a device for telephoning with a selectable telephone tariff, which enables an operator to select a specific telephone tariff from selected telephone tariffs by selecting a telephone operating mode and thus to influence the telephone charges to be paid by them

In the known methods and devices for telephoning, the telephone charges to be paid by the participants are determined as a function of a telephone tariff and the duration of the telephone call. In normal calls, the telephone tariff depends on the distance between the telephone subscribers. a lower telephone tariff applies in the urban area than for long-distance calls The telephone number entered by the dialing person determines whether it is a local call, a long-distance call or an international call, and the corresponding tariff is charged

When entering certain prefix numbers. For example, 0130. 0190. special tariffs come into force, for example where no telephone charges or particularly high telephone charges are charged. With these known telephone methods, the calling telephone user uses certain services, for example a free help desk or the opportunity to get to know other telephone operators relatively high telephone numbers. and a telephone fee corresponding to the service used and the duration for the use of the service for the user of the service is due

For normal telephone calls between two or more (conference calls) telephone subscribers, there is no possibility for the dialing subscriber in the previously known methods for telephoning. to influence the telephone number high The telephone number in normal telephone calls, in which no special services are used, depends in the previously known telephone methods only on the telephone number entered, ie on the distance between the telephone subscribers

It is therefore the object of the invention to provide a method and a device in which the dialing telephone subscriber has the possibility of selecting the telephone tariff to be paid according to his personal financial possibilities and preferences from a group of predetermined telephone rates This object is achieved by a method having the features of patent claim 1 and a device having the features of patent claim 18

A line 36 connects the control unit 6 to a timer 37 which emits a timer clock signal Device is powered by a power supply circuit 38

The device according to the invention shown in FIG. 1 essentially has two operating states. In a first operating state, the telephone set 1 is off the call line 2a. 2b directly connected to the telephone network 4, ie the call line 2a. 2b is enabled, and no coupling is made to the call line 2a via the coupling circuit 3. 2b coupled In this first operating state, normal telephoning between an operator who speaks on the telephone set 1 and any other person is possible, which speaks on a telephone set connected to the telephone network 4

In a second operating state, messages which are in the

Message memory 12 are stored in the call line 2a. 2b coupled In a first embodiment of the invention, the call line 2a. 2b between the telephone subscribers is interrupted during the coupling of the messages, and the telephone subscribers hear the message coupled in via the signal line 14 and the coupling circuit 3 from the message memory 12, without a normal telephone call being possible. In a second embodiment of the invention, the message is transmitted during the second operating state the signal line 14 and the coupling circuit 3 are coupled onto the call line 2a, 2b in such a way that they are superimposed on the call, i.e. normal telephoning between the telephone subscribers is possible, but the telephone subscribers also hear the news in the background. The control unit 6 outputs via the first control line 5 a operating state control signal to the coupling Circuit 3 from At least one acoustic night is stored in the message memory 12. The night memory 12 can be a random access memory RAM, a read-only memory ROM or a removable storage medium. For example, a CD-ROM with a corresponding reading unit, act on the fourth control line 11, the control unit 6 controls the night memory 12. So that a specific night stored in the night memory 12 via the signal line 14 and the coupling circuit 3 during the coupling operating state on the call line 2a. 2b is coupled in. The selection of the messages stored in the message memory 12 by the control unit 6 via the fourth control line 11 is carried out either cyclically in preprogrammed order, randomly by a random number generator contained in the control unit, or correspondingly personal data entered by the operator via the feedback line 13 Message memory 12 from a feedback to the control unit 6. if a via the coupling circuit 3 on the call line 2a. 2b coupled-in night is ended In the message memory 12, analog or digital data are stored which represent an acoustic night, for example an advertising message. In the case of digitally stored messages, there is also a digital / analog converter (not shown) for converting the digital messages into an analog one via the coupling circuit 3 coupling signal provided

In a preferred embodiment of the invention, a circuit device 10 is also provided which is controlled via the control line 9 in such a way that during the coupling-in state. in which the stored message on the coupling circuit 3 on the

Call line 2a. 2b is coupled in, at the same time this night is delivered via loudspeaker 17

In the preferred embodiment of the invention shown in FIG. 1, a pre-announcement signal memory 19 is also provided, which is connected via the fifth control line 18 to the

Control unit 6 is connected In the pre-announcement signal memory 19, at least one acoustic pre-announcement signal is stored, which is transmitted to the call line 2a via the signal line 20 and the coupling circuit 3. 2b is coupled when the phone call time. in which the call line is released, is nearing the end and will soon be switched from the normal telephone operating state to the coupling operating state by coupling the

Advance signal from the advance signal memory 19 to the call line, the speaking telephone end subscribers are informed that the normal telephone call is ended in a short time and an acoustic message is coupled onto the call line, whereby either the conversation is completely interrupted and the telephone end subscribers only hear the acoustic night, or the acoustic message can be heard in the background during the conversation Pre-announcement signal memory 19 stored pre-announcement signal is an acoustic warning signal, for example a series of warning tones, wherein the time interval between the warning tones preferably decreases at the end of the normal telephone conversation time

In a further embodiment, not shown, the announcement of the

Change of operating state not by coupling an acoustic warning signal, but optically via the display 8, for example by a flashing signal. In a further embodiment, the advance notice is given by a combination of optical and acoustic warning signals

In the preferred embodiment with existing circuitry 10, this is

Advance notice signal simultaneously via the signal line 15b. 16 given to the speaker 17

By means of the advance notice signal, the telephone end subscribers can adjust themselves to the fact that the normal telephone operating state will soon be switched over to the night coupling-in state, in a preferred embodiment of the operator the display 8 showing the remaining normal conversation time via a countdown number or a backward number

The function memory 22 is used to store functional dependencies. The first function is the functional dependency of the relationship between telephone call time. or the time during which a normal telephone call can take place via the call line 2a, 2b, and the break-in time. d h the time at which messages via the coupling circuit 3 on the call line 2a. 2b are coupled in or loaded in, depending on a telephony operating mode selected by the operator via the keypad 33, stored in the function memory 22. The second function in the function memory 22 is the functional dependency of the telephone call time charge. d h the fee. which is incurred for a telephone call time, from the selected telephony mode and from the distance specified by the telephone number between the telephone subscribers. The first and second functions are stored either in tabular form or as function formulas

The functions stored in the function memory 22 are not shown in FIG

Embodiment can be coupled out via the telephone network 4, the call line 2b and the coupling circuit 3 to a buffer store contained in the control unit 6 and can be written into the function memory 22 via the line 21. This enables the operator of the telephone network 4 to overwrite the functions stored in the function memory 22 and to program new tariffs This reprogramming is secured by known cryptic procedures The control unit 6 is connected via a line 36 to the timer 37, which emits a clock signal. The clock signal enables the control unit 6 to determine when the telephone conversation time or the recording time has ended and must be switched over to the other operating state

Via the lift-off sensor 23, the control unit detects when the telephone set 1 of the device according to the invention is lifted by the operator. The control unit 6 is activated by a lift-off detection signal emitted by the lift sensor via line 24 and the method according to the invention is started

The phone card reading / writing device 25 is used for inserting a phone card as a value carrier whose stored value is recorded by the control unit 6 via the reading line 26 and which is described via a writing line 27 when a telephone fee is charged accordingly

The operator can throw coin money into a deposit money store 29, the content of which is detected by the control unit 6 via a money storage content detection device 31. The control unit 6 controls the money store 29 via a control line 28 so that it is emptied into a coin collecting container in accordance with the telephone charges incurred

The keypad 33 has a plurality of keys. Via which the operator or the end user speaking on the telephone set 1 can enter a desired telephone number and select a desired telephone mode

The display 8 which can be controlled via the second control line 7 shows the operator the offered ones

Telephone operating modes with the different telephone tariffs Via the display 8 the operator is asked to enter the desired telephone number via the keypad 33 and to select the desired telephone operating mode

In preferred embodiments, the display of the operator can additionally display information, for example about the ratio of the break-in time to normal telephone conversation time. the remaining normal telephone conversation time via a countdown payer as well as a warning display indicating that the normal conversation mode will soon be switched to the single mode A presence detection sensor 35 detects the presence of the operator, for example in a telephone booth, and outputs a presence detection signal to the control unit 6 via the detection line 34, which enables the control unit 6 to detect the presence of the operator. In a preferred embodiment, the control unit 6 checks if the the calculated telephone fee is below an adjustable fee dialing value, the presence of the operator and, if the absence of the operator is determined, interrupts the call line 2a. 2b The presence detection sensor 35 can be designed, for example, as a touch sensor attached to the telephone receiver of the telephone set 1. If the operator selects a telephone mode with a very low telephone tariff, for example a free telephone number via the keypad 33, any telephone number is output via the Keypad 33 and then moves away from the device according to the invention, the control unit 6 detects the absence of the operator via the presence detection sensor 35 and interrupts the call line 2a. 2 B

The presence detection sensors 35 are preferably touch sensors attached to the telephone receiver of the telephone set 1. however, in another embodiment. in which the device according to the invention is installed in a telephone booth, further sensors are provided, for example a pressure sensor, which detects whether an operator is standing on a standing platform

In a further embodiment, presence is recorded by evaluating that via the call line 2a. 2b exchanged analog call signals or the exchanged digital call data take place in this embodiment, not shown, the control unit 6 monitors the analog call signals or the digitally transmitted call data via a call data acquisition device connected to the call line 2a, 2b and checks whether a call is being conducted, ie whether the call signal amplitude changes or call data blocks are still being transmitted

The method according to the invention and the mode of operation of the device according to the invention shown in FIG. 1 are explained below with reference to the flow chart shown in FIG. 2A, 2B

The control unit 6 checks time-cyclically in a step S 1 whether the lifting sensor 23 has detected a lifting of the telephone set 1 or whether the telephone set 1 has been lifted. In another embodiment, the lifting of the telephone set 1 can also take place via a line 24 from the lifting sensor 23 the control unit 6 issued interrupt signal take place after lifting the Telephone apparatus 1, the control unit 6 is activated and shows the various offered telephony operating modes via the display 8 in step S2. In the method exemplified in the flowchart FIGS. 2A, 2B, three different operating modes are offered to the end user via the display 8. The operating modes offered to the telephone end user are as follows

In the first mode of operation, the so-called "zero tariff", the end user does not incur any telephone costs, i.e. the tariff for this telephony mode is zero, regardless of the telephone number entered, however, for this type of telephony mode, the ratio between the recording time for messages is from the message memory 12 via the coupling circuit 3 to the call line 2a, 2b, and the normal telephone conversation time high The telephone subscribers hear, for example after two minutes of normal telephone conversation time, an acoustic message for one minute, for example an advertising message, i.e. the ratio between the recording time and the telephone conversation time a half

In the second operating mode, the so-called "reduced tariff, the tariff is reduced compared to the normal telephone tariff. And the ratio between the break-in time and telephone call time is lower compared to operating mode 1. For example, for two minutes of normal telephone call time, an acoustic night is coupled in for half a minute, ie the relationship between the break-in period and the telephone conversation time is emviertel

In the third mode of operation, the so-called "normal tariff, the normal telephone tariff is billed and there are no acoustic noises coupled onto the call line 2a. 2b, i.e. the telephone subscribers can usually make calls at the normal tariff without listening to advertising messages, for example

The display 8 can be used to display any number of predefined operating modes in step S2. The operating modes can range from an operating mode with a very low tariff and a very high proportion of recorded messages, that is to say with a very high ratio of recording time to a normal telephone conversation time vary to an operating mode with a high normal tariff and no recording time. Any gradation is possible

In step S3, the operator who has lifted the telephone set 1 is requested to select one of the operating modes offered via the display 8 using the keypad 33 In a step S4 it is checked whether the operator has printed a key 1 assigned to operating mode 1 in the keypad 33 or not. If the operator presses the key 1, the control unit 6 recognizes in step S5 that the operator has operating mode 1, ie "zero". Tariff, selected, the check in step S4 shows that the operator has not pressed the key 1. In step S6, it is checked whether the operator has operated the key 2 assigned to operation type 2 on the keypad 33, and the query in step S6 that the key 2 is printed by the operator, the control unit 6 recognizes in step S7 that the operator has mode 2, ie the "reduced key". Has selected the check in step S6. That the key 2 assigned to operating mode 2 was not printed is queried in step S8 whether the operator has operated a key 3 assigned to operating mode 3. The check in step S8 results in this. that the operator has pressed key 3. Control unit 6 recognizes in section S9 that the operator has selected the "normal tariff" operating mode. If the check in section S8 shows that button 3 assigned to operating mode 3 was also not printed and therefore none of the operating modes offered was selected, the section S 10 determines that there is an input error, and the control unit 6 returns to step S2 after informing the operator of the presence of the input errors by means of the display 8.

After the control unit 6 in the sheds S5, S7. S9 has determined. Which of the offered modes of operation is desired by the operator, the end user or the operator is asked via the display 8 in step S 1 1 to enter a desired telephone number via the keypad 33

The control unit 6 detects via the input line 32 the telephone number entered by the operator via the keypad 33 in step S 12 using a calculation device present in the control unit 6. for example a CPU. is calculated as a function of the first function of the telephone tariffs stored in the function memory 22 for the selected operating mode and the telephone number entered in the step S 13. The dependence of the telephone number on the telephone operating mode and the telephone number is a functional dependency in the function memory 22 as a function or in tables Saved In mode 1 "zero tariff, the tariff is independent of the telephone number, regardless of whether it is a long-distance or local voice, zero. In mode 2" reduced tariff the tariff is dependent on the telephone number, but reduced compared to the normal tariff In operating mode 3 "normal tariff, the tariff calculated in step 13 also depends on the telephone number entered. However, the normal or maximum telephone tariff is calculated After the calculation in step S13, input patterns are determined in step S14, with which the nights stored in night memory 12 are transmitted via the coupling circuit 3 to the call line 2a. 2b are coupled in. This import pattern depends on the telephony operating mode selected by the operator. If the operator has opted for the free zero tariff (operating mode 1), messages from the message memory 12 are sent for the duration in accordance with the second function stored in the function memory 22 recorded or coupled in on the call line Naturally, the temporal ratio of recorded messages to normal telephone call time is higher, the lower the selected tariff is. The advantage of cost savings from the operator's point of view is the disadvantage of a longer or more frequently coupled night. For example, a long-lasting advertising message, compared to the telephone unit spared the telephone charges of a separate payment device, not shown, are recorded by the control unit 6. The telephone subscriber spared the telephone subscriber is taken over by the telephone network provider, for example by the advertising message provider

The messages stored in the message memory 12 may be preferred

Embodiment via the telephone network 4 and a decoupling circuit, not shown, can be entered into the night memory 12

After the control unit 6 in step S 14 the import pattern. with which the messages stored in the message memory 12 on the call line 2a. 2b are to be coupled. it is checked in step S 15 whether the operating mode entered is operating mode 1, ie zero tariff. In step S 15 it is found that the operator has selected the free zero tariff. in step S16, a message stored in the message memory 12, for example an advertising message, for the duration of the import time via the coupling circuit 3 onto the call line 2a. 2b coupled in After the end of the import time, the control unit 6 interrupts the coupling in of the messages via the first control line 5 and switches the call line 2a in step S17. 2b free for normal telephone calls. The control unit 6 then checks in step S 18 whether the call has been interrupted by one of the end users. and returns when the check shows that the conversation is interrupted. back to the initial state If it is recognized in S 18 by the control unit 6 that it has not yet been replaced, a message is coupled in again in step S 16. The loop S 16. S 17.

S 18 is run through until one of the end participants interrupts the conversation

If the control unit determines in step S 15 that operating mode 1 has not been selected, ie either mode 2 "reduced tariff or operating mode 3" normal tariff, no free calls are possible, and the operator is shown on display 8 in step S 19 asked to e en Carrier of value, for example a telephone card, into the telephone card reading device 25 or coin money or a bank note into the money store 29 or in step S20 the control unit 6 checks whether the telephone card is valid or whether the inserted coins are valid. In the Sntt S21 the control unit checks 6, whether the operator has opted for operating mode 2, ie for the reduced tariff, or for operating mode 3, ie normal tariff. The query in step S21 shows that the person has selected the reduced tariff. an acoustic night is first played onto the call line 2a, 2b for the duration of the recording time determined in step S14 in step S22 and then the conversation is activated for the duration of the telephone call time in step S23. The value carrier introduced in step S24 is then released by the step S24 S 13 calculated telephone fee is reduced, ie the calculated telephone fee is debited from the telephone card inserted into the telephone card reading / writing device 25 via the write line 27 or the money storage 29 is emptied via the control line 28 in accordance with the fee. Then in steps S25 and S26 checks whether one of the end users has hung up or the telephone card or the cash store is empty. If neither of the end users has hung up or the phone card or the money store is empty, the method returns to step S22. Loop S22. S23. S24. S25. S26 is run through until either one of the telephone end subscribers interrupts the call or the value carrier has a lower value than the calculated telephone fee If one of the telephone end subscribers interrupts the call or if the telephone card has a lower value than the calculated telephone charge, the telephone card becomes in step S27 or the rest of the money returned

If it is determined in step S21 that the operator has opted for the third operating mode, that is, for normal telephoning. In step S28, the control unit 6 releases the call line 2a, 2b via the control line 5. The normal telephone fee is then debited from the value carrier in step S29 in steps S30. S31 is checked whether either one of the telephone subscribers has interrupted the call or the value carrier has a lower value than the calculated telephone fee. If this is determined, step S27 is reached. and the remaining money or the phone card is returned to the operator

That in Fig. 2A. 2B can be expanded by any other operating modes. Operating mode 1 and operating mode 3 represent two extreme cases facing each other. namheh on the one hand a free phone call with a very long total record time. and the operating mode normal telephone calls without importing a message

3A shows in detail the import of a night as in steps S16. S22. S28 in Figure 2A. 2B takes place in step S40, an internal time counter contained in the control unit 6 becomes zero reset and a night stored in message memory 12 is coupled to the call line in step S41 until the internal time counter, which is paid up (Schntt S42). reached a value Nz in section S43, which corresponds to the recording time or news time

In an alternative embodiment, a night stored in the night memory 12 is not recorded for the duration of a predetermined night time, but instead outputs a feedback signal via the feedback line 13 to the control unit 6 and informs the control unit of the end of the recorded night, so that the latter Control line 5 controls the coupling circuit 3 to enable the call line 2a, 2b

3B shows the section S 17, S23, S28 shown in FIG. 2A, 2B in detail. The internal payer contained in the control unit 6 is reset in section S50, and the call line 2a, 2b is controlled by the control unit 6 and by the coupling circuit 3 unlocked in section S51 for normal calls. The internal payer is increased in section S52 until it is determined in step S53 that the call time is over

If it is determined in a preferred embodiment that the call time is almost over, that is to say that the internal payer has reached a certain value below the value Gz, the pre-announcement signal stored in the pre-announcement signal memory 19 is coupled onto the call line in order to pre-warn the change in operating state

Fig. 3C shows that in Fig. 2A. Steps S24, S29 shown in detail in FIG. 2B In step S60, the value stored on the telephone card or the monetary value present in the money store is determined and the telephone fee due for the call is calculated by the control unit 6 in step S61 as a function of the telephone tariff calculated in step S13 The calculated debit value is from the

Telephone card debited via the write line 27 or via the control line 28 from the money stores in the Schntt S62

The method described above can be modified in many ways. In a preferred embodiment, an acoustic message is coupled onto the call line 2a into the telephone set in step S1 immediately after the handset is lifted

The method according to the invention described above is also versatile. It can preferably be used in a public or privately operated telephone booth. An application for pnvate telephones is also possible. The control unit 6 shown in FIG associated coupling circuit 3, the pre-notification memory 19, night memory 12. the function memory 22 preferably arranged centrally at the operator of the telephone network 4. The selection of the telephone mode is made via the keypad 33 of the private telephone apparatus 1 and is carried out via the voice line 2a, 2b of the central inventive method provided by the telephone network operator. Notification communicated The device according to the invention is activated by monitoring the call line 2a, 2b

4 is a diagrammatic representation to explain the method according to the invention. The x-axis shows the course of time and the y-axis the telephone charges incurred as a function of the selected telephony mode. In the telephony mode 1, ie the free zero charge. there are no costs for the operator, that is to say the costs remain constant over the course of time at zero. The relationship between the record-in time at which the messages stored in the night memory 12 are coupled onto the call line 2a, 2b and the telephone call time. That is, the activated talk time without coupling messages and is in the example shown in FIG. 4 at 1 1. In order to be able to make calls free of charge, the telephone subscribers therefore hear, for example for one minute of normal calls, an advertising message or a message for one minute

In the telephone mode 2. That is, with a reduced tariff, telephone costs or fees are incurred, but they are lower than in the telephone mode 3 shown in FIG. 4

Example is the relationship between the break-in time or news time and the phone call time 1 3

In telephony mode 3, no messages are coupled onto the call line, but the charges incurred are correspondingly high, ie the normal telephone rate is charged

Figure 5A. 5B, 5C show an example of a configuration of the information displayed on the display 8. FIG. 5A shows the initial display. in which the operator is asked to use the device according to the invention by pressing a key 40. Further keys 41 can be provided. which are used to activate other services, such as a free emergency call, to

When the key 40 is pressed, the display appears in FIG. 5B. After lifting the handset and pressing a key 42, the inventive method shown in Gig 2A, 2B is activated and the display is shown in FIG. 5C. A desired operating mode is selected via the keypad 33 and the selection confirmed by pressing the key 41
