Information / Kommunikation
A Telecommunication operator (further denoted asTelcom operator) often needs to distribute messagesto his customers. He wants to offer new services to itscustomers, announce some price changes, give ex-cuses for malfunctions, give warnings for invoices,which have to be paid, or for costs which are runninghigh, give an indication, that email messages arewaiting for him and so on. Besides the information,there is also a need or a desire to distribute advertis-ing messages, either to have an additional income, orto reduce prices.
At the other hand, more and more telephone sub-scribers have a display function. On most ISDNequipment, this display is standard, but also analogsubscribers can have a display function. This displayfunction is at the first place used for display of thecalling line identification and for display of the ad-vice of charge for the actual telephone call. The cur-rent invention proposes the development of a newfeature for the Telecommunication operator, in orderto use the display function and the customer premisesfor distribution of general information, which is notnecessarily related anymore to one call.
The feature encompasses a database in the publictelephone exchange, which stores the messages to bedistributed. In order to send personalized messages,an additional database on subscriber level is kept.The information in this database has priority abovethe information in the database on exchange level.
In order to not disturb the normal call proceedings,and in order to be sure that the message is read by thesubscriber, the message is displayed at the customerpremises during call setup. There is always a timeinterval between the end of dialing of the called sub-scriber digits and the answer of the called subscriber.In case that the called subscriber does not answer, thetime can even be rather long. This time is normallynot used by the calling subscriber for any other ac-tivities. Hence, it is very likely that the message getsthe attention of the calling subscriber.
The subscriber should have the choice to accept orrefuse the new service, by which he can get unat-tended messages. In case he accepts the service, theTelcom operator can offer him some price reductions,especially in the case the Telcom operator uses theservice for distribution of advertising messages.
For some calls, e.g. internet calls, the time betweenend of dialing and answer is expected to be short. Thenew feature should be able to detect such calls and tosend only short messages in these cases.
In general, the time for displaying messages is lim-ited; therefore the messages should be written in acondensed language, using abbreviations as much aspossible.
A further idea is to develop a new display function onthe customer premises, which permits to display themessages in a kind of pictorial langua...
