The invention relates to a circuit arrangement for telecommunications, in particular telephone systems, in which the counting pulses accumulated for the connections to record the charges are stored in central memories and processed in a central fee calculator.

In such systems, the work of the telecommunications billing centers Simplified to the extent that the meter reading is used to create the billing does not need to be read or photographed to facilitate creation. Each Subscribers can be assigned a memory section in the central memory in which all counting pulses or charge units that accrued for connections established by the subscriber are to be saved. Each incoming counting pulse can be compared to the previous one via the charge calculator given fee status, d. H. to the existing sum of the fee units caused, can be added. To prepare a fee invoice for the participant is in each case with Expiry of a billing period, e.g. B. at the end of each month, the then accrued amount of fee units to the telecommunications billing center, e.g. B. to transmit by data transmission, to there, taking into account other fees, including the basic fee, to be processed.

The object of the invention is to further simplify the creation of the fee invoices. Achieved this is because the central fee calculator for the calculation of flat fees (e.g. the basic fee, special flat-rate service fee) and / or for evaluating incoming metering pulses (Conversion of the incoming counting impulses into a number of charge units corresponding to a special service) an encoder and / or a multiplier is assigned and the central charge computer also has access to memories in which information about the type of connection (ζ. Β. individual or two-way connection) and / or the authorization (e.g. for special services) of the subscriber and / or the use of special services by the participants are stored.

With the invention, it is possible in a particularly simple manner to take into account flat-rate fees due to a special type of connection or authorization to use special services during or for the creation of the billing. In those cases in which a special service does not include a flat fee, but rather an assessment of each individual circuit arrangement for telecommunications,
especially telephone systems with central
Billing

Named as inventor:

Dipl.-Ing. Karl-Heinz Widdel, 8033 Krailling -

Counting pulse is loaded, the necessary evaluation is only possible with the invention. There the required information on the type of connection and / or authorization and / or use of special services are stored in centrally controlled systems anyway, is in these systems no additional memory overhead to simplify the creation of billing invoices necessary. In other systems it is generally not possible without special memory requirements to introduce new special services, so that here too with the introduction of special services and the Authorization to use the special services for the preparation of the fee invoices taking into account the lump sums required storage are provided anyway have to. The same applies to the type of connection, e.g. in systems in which, with regard to the Flexibility of the system is differentiated between call number and connection position number and accordingly Memory for converting one number into the other must be provided.

In systems in which the memory is used to store information about the type of connection and / or Authorization already exist, can when controlling this memory by the charge calculator the then existing central control device as with the request to set up a connection be used by a subscriber while in facilities in which the memory only become necessary with the admission of special services, expediently with the charge memory can be combined into a correspondingly large memory block, in which case

809 510/33

Access to these memories is required each time the connection is established.

As special services are z. B. conceivable among other things: the so-called call waiting when reached as occupied, desired participants, intrusion on existing connections, conference connections, the call transfer or forwarding or the telephone break, in the case of the erne free participant position is not reached by incoming calls at the request of the called subscriber.

In the figure, an embodiment of the invention is shown. A block diagram of a telephone system to which the subscriber station TN is connected is shown. Via the switching facility

Special service or the type of connection can be contained in the charge memory GSP together with the charge units or in memory areas separate from the charge units.

In telephone systems with a central memory SP , the information can be taken from the corresponding memory areas - the connection memory area, the authorization memory area and the connection type memory area - of this central memory ίο SP at any time. The charge memory GSP of the central charge computer can then also be part of this central memory SP as a special memory area or in a memory area that also contains other information. Especially

device VE , the subscriber of the subscriber station 15 can be connected to other subscribers special in program-controlled telephone systems TN. The charge calculator can do this in whole or in part in the switching equipment shown as a block in FIG
include both the selector or coupler, e.g. B. a
Coupling field marked over a wide area by a central control unit ST , as well as the subscriber line 20
circuits of the connected subscriber stations
and the relay sets, e.g. B. connection or feed sets for internal and external traffic in incoming and outgoing direction or to

Feeding a calling or called subscriber. »5 memories RSAS and RSBS, as well as those for the Er-The central control unit ST receives its information from a special special service - des mations for the switching through of connections

calling subscriber requesting through-connection are issued as dialing characters, and 30 already mentioned charge memory GSP with on the other hand an identifier JD which identifies the subscriber station requesting the associated charge information register GJR and connection
and other information about them, if applicable
Student position determined.

The information about the calling or about 35 a coder C and a multiplier M. To called Teünehmerstelle can in dependency data transmission from and to the Fernmelderechvon its kind and depending on the design of the telephone system for example in an associated one of jeweüigen subscriber station memory area of the charge information memory GSP and / or are explained in detail in the arrangement shown in FIG. Relay sets RSAS for calling subscriber stations It should be assumed that the subscriber and RSBS for called subscriber stations stored subscriber station TN a connection, e.g. B. a or be cached, or they can remote connection has established and that during the one of the switching devices VE associated with the connection counting pulses are taken in a Neten central memory SP . Arrive at a certain time interval. In a first case z. B. at the beginning or during the system without a central charge calculator connection would be the call number of the calling these counting pulses the subscriber counter in the partial subscriber station in the memory RSAS and, if subscriber connection circuit or one of the subscribers, a so-called charge reversal, ie an order possibly in the office individually or at a load of a called subscriber required and 50 lacing point assigned charge printer or possible, the call number of the called part - a Speinehmers upstream of this charge printer stored in the memory RSBS. Everyone is more likely to influence. Even in arrangements with central billing computers that come in while a connection exists, the billing computer can now generally provide counting pulses, which are processed at least one, for which purpose the above-mentioned memory allow the counting pulse to be buffered in order not to change the subscriber's call numbers flawless processing of all possibly equally absolutely necessary, since each incoming counting time to enable incoming counting impulses to initiate a new identification process. On the other hand, it is conceivable to store the counting pulses running in the subscriber line circuit in the memory RSAS or 60 or at a connection point, e.g. B. to collect in the feed set of the RSBS and at the end of the connection to process the calling subscriber station TN or a memory area of the storage pulse assigned to this sum of the counting feed set received for this connection. The information can be arranged chers RSAS. For further considerations regarding the use of a special service, it should be assumed that the (special service information) can also be stored in the intermediate memory for counting pulses, RSAS and RSBS memories, while a single counting pulse is temporarily stored and the information (special service information) is saved in A memory area of the RSAS memory is assigned to the authorization to use a memory that is used as a memory for information for

be included central control unit ST or take over the central control unit functions of the fee calculator.

As can be seen from the above description, is the demarcation between the fee calculator on the one hand and the memory on the other hand of subordinate importance for the invention. Hereinafter it should be assumed that both the

Wake-up service - only for example provided facilities UV, UG and AU belong to the central fee calculator. This also contains the

associated address control AS and associated cyclically operating address generator AG. The actual arithmetic circuit contains an adder ^,

nungssteUe od. The like. A data receiver DE and a data transmitter DS is used.
The following is the mode of action of the

the fee recording is used and all meal rates for calling subscriber stations fixed or temporarily assigned for a connection.

When a counting pulse for the subscriber station TTV arrives in the memory RSAS, if the address of the subscriber station TN is not already stored there, an identification process is initiated by the identifier JD , which transfers the determined address to the corresponding area of the relay set RSAS . When a counting pulse arrives on line 1, the address control AS of the charge computer is activated by the address via line 2 and mixer M2, and the total of charge units contained in charge memory GSP is transferred to charge information register GJR . The incoming counting pulse is on line 2 at the input of the multiplier M and is provided that this counting pulse corresponds to a fee unit, because z. B. no special service was claimed, passed on unchanged via the line 3 and the mixer MS to the input S2 of the adder ^ and added to the sum of the fee units, which is pending via the line 4 at the input 51 of the adder ^. The new sum of the fee unit increased by one fee unit is transferred to the fee information register GJR via the line 5 and the mixing gate M 3 and is stored from there in the original location of the fee memory GSP .

Was the participant TN claimed a special service, such as B. a data transmission or a conference call that requires a conversion of the incoming counting pulses, because each incoming counting pulse for the data transmission corresponds to several charge units, the use of the special service by the subscriber of the subscriber station TTV on line 6 from the memory RSAS is indicated by means of special service information . This identification, which is either entered by the subscriber by dialing code numbers, e.g. B. with number of a conference transmission, or z. B. can be automatically effected during the transition from telephony to data transmission, has an effect on the mixer gate Ml and the line 7 on one input of the and gate £ / 7. By a device controlling the charge calculator, not shown, whenever a counting pulse is processed by the charge calculator, control potential is switched on to points P 6 and P1 , so that when the special service information is present on line 6, it is always via AND gates Ul and Z78 reaches through to the multiplier M , which converts each individual counting pulse by multiplication into several charge pulses. Further processing then takes place in the manner described. .

Accordingly, a flat fee for the use of a special service, e.g. B. for an assignment, inquiry, for intrusion, call waiting od. Like. Are calculated if z. B. when processing a counting pulse, not only the storage element used to temporarily store the counting pulse in the RSAS memory, but also the storage element used to identify the use of the special service is deleted each time a counting pulse is processed.

If the device controlling the charge calculator is designed so that when a counting pulse is processed, control potential is applied to points P 5 and P 6 , the special service information acts on line 6 via mixer Ml and line 7 and via AND gates Ul and U 6 and the mixing gate M 4 on the input of the encoder C , which converts a flat rate into charge units from the special service information, which is added to the old sum of charge units via the line 8 and the mixing gate M 5 as described.

Possible modifications of the previously described parts of the fee calculator will now be considered again below. It is Z. B. conceivable that in a system for the use of a special service either only a multiplication or multiplication of each individual counting pulse is required or only a flat fee is to be paid. Accordingly, the charge calculator can then be equipped with only one multiplier M or only with one encoder C. In systems in which both types of load are required for special services, it is advisable to provide different outputs from the RSAS memory. The line 6, like the mixing gate Ml, would then have to be provided twice. The output of one mixing gate Ml would then, as shown, be connected to the AND gate Ul and the output of the other mixing gate Ml directly to the gate U 6 . In this case, the device used to control the charge computer would have to apply control potential to points PS, P6 and P1 when processing each counting pulse.

As with the calling party, you can also proceed with the called subscriber if z. B. a reversal of the charge, that is, a charge of the called subscriber station with the incoming counting pulses for a connection, is possible. Lines 9, 10 and 11 of the memory RSBS correspond to lines 1, 2 and 6 of the memory RSAS. Furthermore, in systems in which a reversal of the fee is not possible, when using a special service by the called subscriber, z. B. in the case of a query by this subscriber, the criteria given by this subscriber to initiate the query not only lead to the storage of the special service information in the RSBS memory but at the same time to the simulation of a counting pulse. The charge units obtained with the multiplication or coding corresponding to the special service information can then be added to the sum of the charge units of the called subscriber.

Of course, it is also conceivable to store different special services differently in the RSAS or RSBS and to effect a correspondingly different multiplication or coding of incoming or generated counting pulses. Furthermore, it is also conceivable that the stored special service information without the presence or formation of counting pulses in the memory RSAS and RSBS are used to calculate a lump sum, in that the presence of the special service information, such as the presence of a charge pulse, initiates processing by the charge calculator .

The variations of billing described so far can basically be used in all known switching systems, especially if the memory for temporarily storing the counting pulses is arranged in the subscriber line circuit instead of the charge counter, because the address for the address control AS can then be derived from the location of the subscriber line circuit and no identification process

a specially provided output of the RSAS memory pending, z. B. can also be stimulated by a given command. The flat fee determination can be initiated at the end of the billing section by corresponding data transmission to the data recipient DE . For an individual evaluation, ie for calculating the fees of an individual participant

a special information in the charge memory can also be made via the memory RSAS. If the subscriber wants to claim a special service for which he has not yet been granted authorization 5, he can, provided that he is authorized to grant himself authorization for this special service, the special service information, e.g. B. store by dialing code numbers in the RSAS memory. The address control AS can

required for address determination. Since special transmission is then carried out by the address pending on line 2 for special services, e.g. B. a data transfer for the storage of the special service information transmission for a data transfer, are generally stimulated as special information. The special, in particular, when the special service subsequently reaches service information via the line 6, which is introduced, in or at the subscriber line mixer Mt, the line 7, which is arranged via the point circuit, is also the special 15 P 3 in this case And-gate U 4 to be controlled and service information for the calculation of a special mixing gate M 3 for the fee information service lump sum or for a multiple register GJR and is stored as special information in the evaluation of each individual counting pulse in Inan-fee memory GSP. In this case, the setting-up service transmission or from the subscriber circuit 20 used to make use of the special service from the special control of the charge computer can be derived for the connection of. Control potential at the point P 3 by one

If, on the other hand, only certain subscribers are to be authorized to use special services and this authorization is to be assignable for the individual special services, it is advisable, if no authorization memory is provided in a system 25, to provide this in the charge calculator. The authorization of a subscriber can there, ie in the charge memory GSP of the charge computer under

the address of the subscriber together with the 30 can also be identified via the line 12, the address sum of the charge unit as special information, while in a common stored or under a special authorized evaluation for all subscribers of the address narrowing address of the subscriber in a special transmitter the address control takes over.
Storage area. It is also possible via line 14 and point P 8 to store the subscriber's addresses in a 35 ner © in a corresponding command to the control memory area assigned to the particular device serving the charge computer. The allocation of the which affects the point P 4 and the disenfranchisement can be done from any point, e.g. B. speaking coding of the fee memory by an officer in the remote office or from the remote GSP in the fee information register GJR and reporting calculation center and, if the special informant, who is directed from there to the and gate! 75, is authorized to do further information leads in encoder C. A z. B. authorizations to be granted or withdrawn, also from the subscriber between the Undgatter t / 5 and the mixing gate M4. The fee calculator is switched buffer storage, in this case via the data receiver DE, a temporary storage or a temporal shift controlled, which after corresponding data transmission 45 exercise the special information in such a way that the address of the fee memory to be controlled is then entered into the fee information on the line 12 and the type of authorization to register GJR accepted for connections angeder line 13 identifies. The sum of the fee units falling over the line 13 via the line and the mixing gate M 3 arrives at the same time and in the correct phase with the special information received by the authorization corresponding special information, the flat fee corresponding to the fee information register GJR in the fee information register GJR at the inputs and is under the influence of the adder A going over the line 12 pending. Regardless of this, and the addressing of the mixer M 2 controlled, whether a setup control AS separate from the flat fee is written into a free memory location of the amount of the total accumulated for the connections by the charge memory GSP . It is there 55 fee units is required or the lump sum is available at any time, especially if it is only required as a fee calculation for the fee after the expiry of the fee and the lump sum fee units required for the connections in a billing section. The connection type, ζ. For example, the sums of local fee subscribers, such as: "Subscriber station with second alarm clock", which are sent via line 8 and line 4 to the two-way or single line or additional information adders, are sent from there to the data transmitter DS , which is used by the flat fee calculation at the end of
Billing section are decisive, are fed as special information. Feedback
the stored special information to the 65
The agency initiating the storage is via the
Data transmitter DS possible.

The transmission can be carried out from one participant

corresponding command from data receivers DE via line 15 to transmit both sums or the sum of both sums.

The authorization or type of connection of a subscriber stored in the charge memory GSP can now also be used for switching processes in the system by z. B. is prevented,

that a subscriber who has not been granted authorization for certain special services uses these special services. It is also conceivable that an effective connection establishment of blocked subscriber stations is completely prevented in this way. As soon as a participant, e.g. B. the subscriber of the subscriber station TW wishes to set up a connection, as already described, his address is determined by identification by the identifier JD and stored in the memory RSAS. The address control AS can be influenced via the line 2 and the mixer M 2, which, since only the address is pending without a counting pulse, controls the special information about authorization and / or connection type of the subscriber station in the charge memory GSP and initiates the transfer to the charge information register GJR . The special information is thus located on the line 15, among other things, at the input of the undgate t / 2. At this point in time, since only one address and not simultaneously a counting pulse was present in the memory RSAS , the device serving to control the fee calculator has a control potential effective via point P1 and thus the AND gate U2 is switched through, so that the special information about the Line 17 is transmitted to the memory RSAS and via this or possibly also directly to the central control unit ST and can influence the connection establishment in a positive or negative sense.

Is it about the use of a special service by the called subscriber station, z. B. to a query from the called subscriber station, then with the submission of the query criterion by the called subscriber, an identification of the called subscriber station is initiated and the address is transferred to the memory RSBS . Since the address is then only available there, the special information of this subscriber station is stored in the charge calculator, the special information is passed on by applying control potential at point P 2 via the AND gate U 3 and the line 18 to the memory RSBS or to the central control unit ST and there the inquiry initiated or prevented.

In systems in which the so-called telephone break is possible as a special service, i.e. a call is diverted to an announcement device that informs the calling subscriber that the called subscriber does not want to be disturbed, the special information stored by the called subscriber in preparation in the charge memory GSP can be used be used for call diversion that the central control unit ST at the address of the called subscriber, if necessary via the memory RSBS, causes this special information to be saved, which is then required by the central control unit ST each time a connection is established.

The wake-up service occupies a special position among the special services. However, in the case of an arrangement according to the invention, its implementation requires very little effort, in particular if an automatic dialing device AU is already provided for a charge announcement to a subscriber. A subscriber who would like to be woken up at a certain time via the telephone can save the special information “wake-up order” together with the wake-up time in the GSP charge memory. The cyclic address generator AG _1, which, as already described, is also provided for billing at the end of a billing period, cyclically supplies the addresses of the memory elements or memory areas in which wake-up requests are to be stored, thus ensuring that the wake-up times are cyclically stored in the charge information register GJR for a time comparison in the time comparator UV, which is under the influence of a clock UG , which sends a signal to one input of the und gate Ul when the wake-up time coincides with the time, so that the address of the subscriber to be woken up in the cyclic address generator is sent to the automatic dialing device AU is routed, which is connected to the switching equipment VE like a subscriber station and establishes a connection to the subscriber station of the subscriber to be woken up. The time can then be automatically announced to the participant by the clock UG .

For an arrangement according to the invention, the special design of the charge memory GSP is of subordinate importance. He can, as a circulating memory, z. B. be designed as a drum store, which rotates synchronously with scanners that scan the individual memory sections or memory areas of the memory RSAS, RSBS or SP . The scanners ensure that the individual pieces of information are processed one after the other. A core memory or some other non-circulating memory can also be used, in which case the scanners can expediently be replaced by parallel selectors for selecting one of several items of information pending processing. Depending on the setting of the scanner or parallel selector, a signal can be sent to the device controlling the charge calculator, which signal then initiates the corresponding connection of control potential to points P1 to P7. The pending information can be processed with varying degrees of urgency. It is also conceivable that programs that are running, e.g. B. the wake-up program to interrupt to more urgent requests, e.g. B. the processing of an incoming counting pulse, preferably to be done. For this purpose, the device controlling the charge computer can be designed as a program-controlled device, if necessary with a stored program. The fee calculator may further at a central location for a plurality of switching devices SU to be provided in common, and then to turn the various switches VE and the charge computer data lines between the memories and RSAS RSBS or SP and are to be provided, where appropriate, buffer memory.
