Abstract

The invention relates to a method according to which, in a switchboard (10), a service feature for recording call data is marked for a subscriber (TlnB). When a terminal of a calling subscriber (TlnA) transmits a call request to the terminal of the subscriber (TlnB) with the mark, a connection (56) is established between the switchboard (10) and a third terminal (40) in addition to the connection (52, 54) between the terminals of the two subscribers. The call data are saved in said third terminal (40). Depending on the signals received by the called subscriber (TlnB) after storage of the data, the call data remain stored or are deleted. The invention provides a method with which the subscriber (TlnB) can control the recording of call data in an easy manner.

Description

Methods are known which print out the number ei Allow a terminal from which a subscriber calls who initiated the connection. This part participant is also referred to as A-participant. Is used such a procedure if the called party, i. H. the so-called B-subscriber, often disturbed by the A-subscriber and the call number of the A subscriber will now be determined should. The printed number can later be saved in one use judicial proceedings as evidence.

So far, conversation data can also be recorded privately, d. H. after they are transmitted to the B subscriber's terminal have been. The B-participant needs a special opening drawing device that he must maintain and operate himself. A judicial recovery of such records is however over quarreled.

It is an object of the invention to record conversations data to provide a simple procedure. In addition, a associated switchboard and an associated pro grams can be specified.

The task related to the procedure is carried out by the Pa Solved claim 1 procedural steps. more educations are specified in the subclaims.

The invention is based on the consideration that the anyway B participants already disturbed by the A participant at the Release the recording of the call data as far as possible should be tet. In particular, it should not deal with maintenance and Operation of a recording device. The Recorder is also often only used for a short time  space needed, for example for a week or a month nat. In order to utilize the recording devices nonetheless, they can be used by several participants.

In the method according to the invention is first in a ver a provision for the B-participant times noted for recording call data. At a Connection establishment request from the terminal of the calling A- Subscriber to the B-subscriber's terminal becomes additional a connection for the connection between the two terminals between the switch and a third end advises to set up. Those coming from the A-subscriber's terminal Data is automatically transferred over the two connections wear. The data transmitted to the third terminal saved. Depending on the after saving the data received signaling of the B-subscriber is the Spei Space to save the data either released, or the data is saved for later reading.

The inventive method ensures that the B subscribers to record the call data initially only must cause the feature to be noted. at for example, he makes an application to the operator of the Ver mediation device. A recording device on the side of the B participant is not required. That on the side of the third terminal device used can be for a large number of participants who use the Leis Request for recording of call data ha ben. The third terminal can be procedures outside the sphere of influence of both participants always set up. If the third terminal is, for example, in a court, so the conversation data later use in a process.

The data coming from the B participant can also be transferred to the third terminal, so that a complete Conversation is recorded.  

The B-subscriber can save the data at the end determine yourself whether the data should remain saved o which are to be deleted. If the data is to be saved, for example, he presses a first function key. Should on the other hand, if the data is deleted, he presses one of the first function key various second function key. to Instead of pressing a function key, it can also be switched off remain a special signaling as a control function be counted on. The B-participant has it in himself to decide which conversations are recorded and who which should and which not. In addition, the choice is achieved that much less call data save as without this option. The store There is therefore space for storing the call data reduce.

In the case of further training, the stored conversation data after checking the signaling independently of one released another call of the called subscriber. The released storage space can be used again immediately. Alternatively, with the release until a new call to the called subscriber. This opens up to the called Participants the opportunity to release their decision to rethink the call data and change it if necessary countries. A call from anyone can be used as a reference call gen participant or another call from the disruptive Use A participants.

At a next training the call data remains if there is no sig nalization saved. When receiving the on the performance feature-related signaling are the call data Approved. With this measure, the B-participant Occurrence of a fault by the A participant of additional Chen relieved operator requirements. Missing one too additional signaling, e.g. B. due to the excitement of the B-  Participant, is not possible. Alternatively, vice versa returns to be proceeded. This has the advantage that the B- Participants explicitly confirmed saving.

Another training course is in mediation direction a connection between a connection unit the calling party side and a connection unit built up to copy the transmitted call data serves. Between the connection unit for copying and one Connection unit on the side of the called subscriber also established a connection. Between the connection Unit for copying and a connection unit on the side of the third terminal, a third connection is established. Thus, the connection unit for copying between the two establishing a connection without the additional feature required connection units looped in. The An the end unit for copying can be used centrally, d. H. from a variety of other connection units.

Alternatively, one is first in the switching facility Connection between a connection unit on the side of the calling subscriber and a connection unit on the side of the called subscriber. Starting from the An closing unit on the called party's side automatically a connection between this connection unit and a connection unit on the side of the third terminal built up. This measure ensures that the Connection between the two participants without delay compared to establishing a connection without the additional Performance feature can be built.

In another development, the third terminal is one Recording device for recording data, e.g. B. a da processing system, a magnetic recording device or a digital recording device. The third terminal can be set up inside or outside the switchboard len.  

At a next training course participant data of the called subscriber stored in the switching center chert. The subscriber data also contain the phone number or a reference to the number of the third terminal. By specifying the phone number, it is determined which end who is included in the recording of the call data that should. This allows the operator for different To offer different numbers for the purpose. So you can Use phone number for recording data, too to be used as evidence before a court. Another phone number can be saved for storing tele use telephone contractual agreements, which also can be used correctly within normal business processes are.

In another training, the number of the call the participant saved and / or output. The Spei chern or output the number is preferably by the third terminal or by an additional unit in the Switching device carried out. The combination of the Features Call data recording and recording the phone number leads to an upgrade of both features times.

The invention also relates to a switching device, to carry out the method according to the invention or one of his trainings is suitable. So that apply above-mentioned technical effects also for the mediators lung device.

In addition, the invention relates to a program when it is off leadership by a processor the inventive method or one of his trainings is carried out. The above the technical effects mentioned also apply.

Exemplary embodiments of the invention are described below Hand explained with the accompanying drawings. Show in it

Fig. 1 is an exchange with the feature "call data recording", and

Fig. 2 shows a switching center with the feature "call data recording" according to a second embodiment.

Fig. 1 shows a switching center 10 , which enables the execution of the feature "call data recording" light. The exchange 10 has, for example, the construction of the exchange EWSD (Electronic Dialing System Digital) from Siemens AG. The switching center 10 contains a main switching matrix 12 , a central processor 14 and connection units 16 to 20 . The main switching matrix 12 serves to switch connections between the connection units 16 and 20 . Furthermore, can be via the group switch 12 connections between the Anschlusseinhei th 16 and 20 and switch the central processor fourteenth The central processor 14 is connected to the main switching matrix 12 via a line system 22 , for example via a bus system. The central processor 14 controls the connection establishment in the switching center 10 depending on the signaling of the connection units 16 to 20 and depending on subscriber data 24 , which are stored in a memory of the switching center 10, not shown.

The connection units 16 to 20 are connected in this order with the help of transmission links 26 , 28 and 30 to the main switching matrix 12 . The connection unit 16 is used to connect a concentrator unit 32 to which a subscriber TlnB is connected by means of a connection line 34 . For example, the subscriber TlnB has an ISDN basic connection (Integrated Services Digital Network). Between the concentrator unit 32 and the connection unit 16 there is a transmission path 36 , for. B. a PCM-30 system (Pulse Code Modulation).

The connection unit 18 is used to connect an intermediate exchange line 38 , which lies between the switching center 10 and a switching center, not shown. Via the switching center, not shown, a recording device 40 can be reached. The recording device 40 is used to record call data that are sent from the connection unit 18 .

The connection unit 20 is used to connect other participants, for. B. a participant TlnA. The subscriber TlnA is connected to the connection unit 20 via a connection line 42 , a concentrator unit 44 and a transmission path 46 . The transmission link 46 is in turn a PCM-30 system.

In order to provide the function “call data recording”, the exchange 10 also contains a copying unit 48 for doubling call data. The copying unit 48 is connected to the main switching matrix 12 via a transmission link 50 .

After the subscriber TlnB has applied for the "call data recording" feature, this feature is noted in his subscriber data 24 . In addition, an address reference to a memory cell with a call number is noted in the subscriber data 24 of the subscriber TlnB, under which the recording device 40 can be reached.

If the subscriber TlnB receives a call, e.g. B. from a subscriber disturbing him, the connection unit 20 includes the central processor 14 in the connection establishment. On the basis of the subscriber number TlnB, it can be determined that the subscriber TlnB has activated the feature "call data recording". The central processor 14 therefore causes a connection to be established between the connection unit 20 and the copying unit 48 , see connection 52 . In addition, the central processor 14 switches a connection 54 from the copying unit 48 to the connection unit 16 . In the connection unit 16 , the further connection establishment in the direction of the subscriber TlnB is initiated. A third connec tion 56 is switched by the central processor 14 on the basis of the telephone number noted in the subscriber data 24 between the copier unit 48 and the connection unit 18 . The connection unit 18 initiates a connection to a terminal that performs the functions of the recording device 40 .

The call data coming from the subscriber TlnA are copied in the copying unit 48 , see cross 58 . The original call data are forwarded to the subscriber TlnB via the connection 54 . The copied call data to the recording device 40 on the connection 56 forwarded and recorded in the recording device 40 . Call data arriving in the copying unit 48 from the subscriber TlnB via the connection 54 are also copied. The original data are forwarded to the subscriber TlnA via the connection 52 . The copied call data are forwarded via the connection 56 to the recording device 40 and are also recorded there.

At the end of the connection between the subscriber TlnA and TlnB, regardless of which subscriber triggers the connection, the signaling coming from the subscriber TlnB is evaluated in the switching center 10 . Comes from the subscriber TlnB an additional signaling in comparison to a connec tion without using the feature "call data recording", for. B. the single operation of the hook switch of a telephone, the connections 52 to 56 are cleared by the central processor 14 without additional signals to the terminal 40 . The saved call data is available for a later reading process.

If, on the other hand, the subscriber TlnB does not receive any signaling related to the “call data recording” feature, the central processor 14 signals the recording device 40 before the connections 52 to 56 are cleared that the previously recorded call data of the last call are to be deleted.

Fig. 2 shows a switching center 10 a for performing the functions of the feature "call data recording" according to a second embodiment. The switching center 10 a is also a switching center of the EWSD type, which has been expanded to include functions for providing the “call data recording” feature. Units that have already been explained with reference to FIG. 1 receive the same reference numerals in FIG. 2, but with the lower case letter a. This applies in particular to units with the reference numerals 12 a, 14 a, 18 a to 24 a and 28 a to 46 a.

Instead of the connection unit 16 , a connection unit 100 is used in the exchange 16 a for connecting the subscriber TlnB. In a memory of the connection unit 100 there are subscriber data 102 which are copies of the subscriber data 24 a. The subscriber data 102 relate only to the subscribers connected to the connection unit 100 , e.g. B. the participant TlnB. The connection unit 100 also contains a copying unit for copying call data, see cross 104 . Furthermore, the connection unit 100 is expanded by functions for the provision of the “call data recording” feature. The functions are explained below.

If the subscriber TlnB requests the feature "Ge talk data recording", this feature is noted in his subscriber data 24 a and 102 . If the participant TlnB is called by a participant, e.g. B. by the subscriber TlnA, the recording device 40 a is included in the connection. When calling the subscriber TlnA, a connection to the connection unit 20 a is first established. The connection unit 20 a determines the connection unit 100 using the central processor 14 a on the basis of the call number of the called subscriber TlnB. With the involvement of the central processor 14 a, a connection 106 is established via the main switching matrix 12 a between the connection units 20 a and 100 . In the connection unit 100 , the connection setup to the subscriber TlnB is continued. In addition to this connection establishment, however, the establishment of a connection 108 between the connection unit 100 and the connection unit 18 a is initiated on the basis of the telephone number stored in the subscriber data 102 in order to reach the recording device 40 a. The connection unit 100 transmits the call number stored in the subscriber data 102 , under which the recording device 40 a can be reached, to the connection unit 18 a. The connection unit 18 a then initiates the further connection to the recorder 40 a.

Call data, which the subscriber TlnA reaches via the connection 106 to the connection unit 100 , are copied there. The original call data are forwarded to the subscriber TlnB. The copied call data are forwarded via the connection 108 to the connection unit 18 a and from there to the recording device 40 a. The call data is stored in the recording device 40 a.

Conversation data that reach the connection unit 100 from the subscriber TlnB are also copied there. The original call data are forwarded via the connection 106 to the subscriber TlnA. The copied call data who passed the connection 108 to the recording device 40 a and stored there.

When the connection 106 is cleared down at the end of the call between the subscribers TlnA and TlnB, the signaling coming from the subscriber TlnB is evaluated. If there is a signaling related to the “call data recording” feature, the central processor 14 a initiates the clearing down of the connections 106 and 108 without additional measures. No additional measures are taken in the connection unit 100 either. The call data of the last call remain permanently stored in the recording device 40 a.

If, on the other hand, the subscriber TlnB does not receive any signaling relating to the “call data recording” feature, the connection unit 100 sends a delete message to the recording device 40 a. When editing this delete message, the previously recorded call data of the last call are deleted, ie the storage space required for storing this data is released. Connections 106 and 108 are then cleared down.

In other exemplary embodiments, the subscriber TlnA is connected to a different switching center than the subscriber TlnB. The procedural steps explained above remain basically unchanged. However, instead of the connection unit 20 or 20 a, a connection unit is used to connect an inter-office line.

The method according to the invention can be used both in fixed networks and can also be used in mobile networks. Furthermore can with the help of the inventive method all types of ü Information that can be transmitted via a switching facility nen - e.g. B. fax information or data processing compliant Information - to be recorded.
