ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a procedure for transmitting information to a predetermined subscriber line or predetermined subscriber lines in a telephone network.
DESCRIPTION OF RELATED ART
Transmission on information over a telephone network is widely known. In prior art, information can be transmitted between two predetermined subscriber lines using computers and modems connected to them. However, such a procedure requires the setup of a connection between the subscriber lines in question. On the other hand, it is also possible to transmit information between subscriber lines by setting up a speech connection between the subscriber lines and using this connection for the transmission of information.
In prior art, no system is known that allows transmission of information to a terminal device that only acts as a passive receiving party, without signaling sent by both parties. At present, however, there is a need for transmission of information independently of the receiver's actions. This means transmitting information by a method in which the information provider activates the transmission without the receiver's acknowledgement. The information or data to be transmitted may consist of commercial advertising information, various performance data service type information or the teleoperator's own advertisements or announcements. Via this arrangement, advertising, marketing and similar information can be directed at given target groups, based e.g. on subscriber location, which can be determined from the subscriber numbers, or on some other corresponding basis. However, the problem is that no such arrangement is known.
SUMMARY OF THE INVENTION
The object of the present invention is to disclose a new type of procedure that makes it possible to fulfill the above-mentioned need for data transmission in a telephone network independently of the receiver's actions. A further object of the invention is to create an arrangement that allows a teleoperator to provide the connections between an information provider and the target subscriber lines.
In the procedure of the present invention for transmitting information to a predetermined subscriber line in a telephone network, which comprises a telephone exchange, a number of subscriber lines connected to the telephone exchange and a terminal device connected to the subscriber line, according to the invention, the subscriber number of the subscriber line acting as a source of information is stored in the telephone network, the subscriber numbers of the subscriber lines to which the information is to be transmitted are stored in the telephone network and, further, according to the invention, the information to be transmitted is stored in the telephone network and/or in a peripheral connected to it and, using a link without actual connection, the predetermined information is transmitted to the predetermined subscriber lines. Thus, when the transmission of information is activated, the information to be transmitted and the predetermined subscriber numbers to which the information is to be transmitted are read from the subscriber line acting as source of information, which subscriber line may have e.g. a computer connected to it, and the information is transmitted in suitable information elements of the signalling used in the telephone network.
As compared with prior art, the present invention has the advantage that the procedure of the invention allows transmission of information to certain subscriber lines without requiring any actions to be carried out at the receiving end. Further, the invention allows information providers to offer their services to their customers without setting up connections between the terminals, which increase the load on the telephone network, while still using telephone network signalling.
The signalling used in the telephone network is preferably ISDN signalling (ISDN, Integrated Services Digital Network), such as ISUP signalling (ISUP, ISDN User Part) . In this case, the information to be transmitted can be transferred to the desired subscriber line in the DISPLAY element of the FACILITY message used in ISDN signalling. The transmission can be performed when the subscriber line is in inactive state, in call setup state or in active state. Thus, the transmission can be carried out completely independently of the subscriber line, i.e. the subscriber line is not required to acknowledge the information transmitted or to react to it in any other way.
In an embodiment of the invention, a computer is connected to a predetermined subscriber line in the telephone network and the subscriber numbers to which the information is to be transmitted as well as the information itself are stored in the computer, and the computer is used to control the transmission of the information to the subscriber lines in question. This implementation has the advantage that the service provider can easily change both the content of the information to be transmitted and the subscriber lines forming the target group.
The subscriber number of the subscriber line acting as data source, as well other information needed, such as the predetermined subscriber numbers to which the data is to be transmitted, can be transferred over the telephone network in the information elements of the SETUP message used in ISDN signalling. On the other hand, the information in question can be stored and transmitted by using the telephone exchange's own control commands, preferably nM
7
commands (MML, Man Machine Language)
In a preferred embodiment of the invention, the transmission of information is activated a. predetermned intervals of time. The time interval can be defined e.g. in a computer connected to the telephone network or to some other network component controlling data transmission. The information is preferably presented in graphic and/or text format on the display of the terminal device or in the form of sound via a loudspeaker connected to the terminal device.
