DE19830716A1 - Spoken announcement outputting method in digital exchange - Google Patents

Abstract

The method involves outputting a spoken announcement with information from and/or about a calling telecommunications subscriber at an analog terminal (3) of a called subscriber, which is connected with a digital exchange (1). A lifting of the terminal of the called subscriber is determined through the exchange. The speech signals are produced or read from a memory through the exchange, and are transmitted to the terminal of the called subscriber. The speech signals are received and acoustically reproduced through the terminal of the called subscriber. An Independent claim is provided for a corresponding exchange implementing the method.

Description

The invention relates to a method for outputting a ge spoken announcement with information from and / or about a calling telecommunications (= TC) subscriber to one analog TC terminal of a called TC subscriber, where the TK terminal of the called TK subscriber with a digi tal switch is connected.  

A method for displaying the number is, for example, be knows from the magazine "Funkschau", issue 10/1998, Sei ten 54 to 57.

Until the introduction of digital telephone systems such as ISDN it was not possible for a called TC subscriber to contact Ge Answer the call to determine who the calling TC subscriber is was. Only in exceptional cases when a called TC Subscriber from an anonymous calling subscriber "Telephone terror" has been suspended or from investigative tech African reasons (for example in the case of extortion Determination of the calling offender) could also earlier in the "analogue age" the trail to the calling TC subscriber traced back and his phone number to the called TK participants are notified, such as be wrote in US-A 4,720,848 or Patent Abstracts of Japan 05048735.

In the case of ISDN terminals, the CLIP procedure is used during the clinic the phone number of the calling TK subscriber, sometimes his name shows so that the called TK subscriber before conversation Acceptance can decide whether he is with the calling TC part wants to be connected or not.

In the magazine article "Funkschau" quoted at the beginning 10/98 is now reported, as is such a CLIP service for analogue telecommunications terminals through inband signaling can be offered from a switching center. To however, a modem is required for coding and decoding called end as well as a display for the visualization of the Call number shown of the calling subscriber required Lich.  

In contrast, the object of the present invention is a To present the procedure of the type mentioned at the beginning, in which in contrast to ISDN methods, no separate data channel for Transmission of a telephony subscriber concerned Information is required before accepting another call On the one hand, this is said to be the case with known analog telecommunications devices necessary modem and visualization display can be omitted nen.

According to the invention, this object is achieved in a surprisingly simple and effective manner by the following steps:

• a) Determine the lifting of the telecommunications terminal of the call TK subscriber by the exchange;
• b) Generating speech signals which contain the information regarding the calling TC subscriber, or Retrieve these speech signals from a memory through the exchange;
• c) sending these voice signals from the switch place on the TC terminal of the called TC subscriber mers;
• d) Reception and acoustic reproduction of this voice nale through the TC terminal of the called TC part taker.

This also becomes the owner of an analog subscriber conclusion without additional technical effort, the number of the calling subscriber before accepting the call experienced and then decide on accepting the call  what so far without additional devices such as modems and dis play facilities only for owners of ISDN subscribers conclusions was possible.

In an advantageous variant of the Ver driving the information includes a spoken and on egg Message of the calling TC part stored in the memory taker. This is called by the called party before the call is accepted TK subscribers, for example, directly from a mailbox plays without a connection between the calling and the called TK subscriber comes about. Before a through switching the called connection becomes a corresponding one Notice acoustically to the called subscriber ben.

A variant of the invention is particularly preferred Procedure in which the information is the phone number and / or includes the name of the calling subscriber. This is likely by far the most important application of the invention Represent procedure and enables those described above Advantages of the known CLIP procedure for the called TC Attendees. The acoustic announcement of the phone number and / or the The name of the calling TC subscriber can, for example, be as Service provided by the network operator is generally automatic table before switching through the connection. The digita The exchange determines the number or name of the calling TC subscriber on the basis of the information available to her Call signaling.

A particularly preferred development of this variant of the method is characterized by the following further steps:

• a) Sending a call acceptance signal from the TK terminal of the called TK subscriber to the exchange, the depending on an operation on the TK terminal of the called TK subscriber to the exchange assigns the call to the TC terminal of the called TC Put through participant;
• b) Put the call through to the TK terminal of the called party TK participant.

This allows the called TC subscriber to actively decide whether to accept the call or not. In the event of a call refusal by the called subscriber, the following additional steps are provided:

• 1. (e ') sending a call refusal signal from the TC Terminal of the called TC subscriber to the Ver agent that depends on an operator action on the TK terminal of the called TK subscriber instructs the operator, the call not to the TC terminal of the called TC subscriber to put through;
• 2. (f ') termination of the connection between the operator and the TK terminal of the called TK part taker.

In the case of refusal to call, an advantageous tone sounds Training after breaking the connection between the Ver center and the TC terminal of the called TC part subscriber to the calling TK subscriber Dial tone. As a result, the calling subscriber notices not that the called subscriber does not speak to him  wants and the required discretion, the prerequisite for one free decision of the called TK participant about acceptance or refusal of a call is preserved.

An embodiment of the invention is also particularly preferred method according to the invention, in which by a predetermined put operating procedure on the TC terminal of the called TC part the process can be activated or deactivated can. Conversely, a method variant is also conceivable offered the possibility to the calling subscriber is a preliminary information about his phone number or his Unlock or block names. Such a block is in ISDN technology as Calling Line Identification Re striction (= CLIR) known per se.

Another variant of the he is used for error handling inventive method provided that in the med at the telephone terminal of the geru open TK subscriber starts a time clock, and that after Ab the call to the TK terminal of the called subscriber is also switched through, if no call acceptance signal from the TK terminal of the called TK subscriber has reached the exchange.

It is also advantageous if after hanging up the telecommunications terminal by the called TC subscriber without prior sending a call acceptance or refusal signal to the Switch another call signal to the TC terminal of the called TK subscriber is switched so that this offered the opportunity to accept the call again becomes.  

In a preferred development of this method variant te is picked up after the TK terminal is lifted again called TK subscriber due to the further call signal Call immediately to the TC terminal of the called TC subscriber switched through. This also allows a called subscriber accept the call that deals with the operating procedure of the Does not know how to accept and refuse calls. Besides, will thereby the time until the final connection is made shortened, which increases the chance that the calling TC Meanwhile, the participant has not already hung up.

The process according to the invention particularly preferably comprises a multi-frequency dialing method, since with the usual impulse electoral procedure a reply from the called TC subscriber to the corresponding exchange in principle is possible, however, with the tone dialing method over the Multi-frequency code a call acceptance or refusal signal especially from the called terminal to the exchange can be sent quickly.

The method according to the invention is preferably used as IN (= Intelligent Network) service by a service provider offered or executed in the relevant telecommunications network, so that the end user with an analog connection the CLIP Can use option for additional fee payment.

One also falls within the scope of the present invention Switching center for switching voice signals to a TC terminal of a called TC subscriber with means for Execution of the inventive method described above steps.  

Further advantages of the invention result from the Be writing and drawing. Likewise, the above mentioned and invented the features further invented in accordance with the invention individually for themselves or for several in be arbitrary combinations are used. The shown and The embodiments described are not intended to be final Understand enumeration, but rather have exemplary th character for the description of the invention.

The figure shows a functional diagram of the connection between the exchange and the called TK terminal in the frame men of the inventive method "CLIP for analog part slave connections ".

In a digital telephone network (such as in Germany exists) is the phone number of the caller known in the exchange of the called party. The he invention relates to digital switching devices, who are able to give you the phone number of the caller To automatically notify participants with an analog connection, so that he can decide whether to accept the call.

In particular, such a system can ar as follows work:

After the ringing signal sounds, the called subscriber picks up the handset and receives from the switching system, the z. B. in a manner known per se for lifting the called endge guesses by measuring the loop current in the affected Line automatically determines the announcement of the number of the calling subscriber. This announcement becomes software controls generated from digitally saved announcement parts and fed repeatedly. Does the called subscriber have his  He decides whether to accept the call or not the (*) = call acceptance and is immediately ver with the caller bound. Up to this point the caller receives the free volume.

If the called subscriber does not want to accept the call, he dials (#) = refusal and can pick up the receiver again hang up. The caller continues to receive the ring tone and is not informed about the refused call acceptance. The following procedure is provided as an option for error handling see:

If the called party does not meet after picking up the handset divorce over the call acceptance, so after a fixed current time, e.g. B. 15 seconds, the conversation by the Ver averaging system switched through. The called TC part is placed pick up the handset again without dialing (*) or (#), he he holds the call signal for the second time. Now becomes the listener picked up again, the call is immediately switched through. So this service is also when switching to analog Connections compatible with fax machines or answering machines.

As a further option, provision can be made for this service to be activated and deactivated independently by the called and / or the calling TC subscriber by means of an agreed operating procedure (for example dialing * 39). In the figure, the digital switching center 1 is shown schematically, which acoustically communicates the number and / or the name of the calling TC subscriber via a TC path 2 to the TC terminal 3 of the called TC subscriber after lifting the handset 4 . By pressing a previously defined key 5 , the called TC subscriber can send a signal in the multi-frequency code or as a loop break to the switching center 1 via a return path 6 on the analog subscriber line, which signals whether the called TC subscriber wants to accept the call or not.

It is also conceivable instead of transmitting the number and / or the name of the calling subscriber or to in addition, the acoustic message that the calling TK participants, for example, on a mailbox for the called TK subscriber, who this may be charged via an operating procedure can without any connection to the call TK subscriber must come about.

The advantage of this method is that the Be analogue subscriber connections without additional connections creation of a modem and a display device via can decide to accept a call. With a telephoto fonmarkt with competing companies has one Company that can offer this service to its customers, a significant competitive advantage.
