COMMUNICATION OF MESSAGES IN THE PHONE NETWORK

The invention relates to a method as defined in the preamble of claim 1 for transmitting a message between terminals in a telephone network.

• 5 Until recently, the telephone network has evolved from a purely technical perspective with an emphasis on automation and rationalization of telephone networks. Call centers have been developed primarily to forward calls, not to provide services.

10 As a result, services have begun to be provided through intelligent networks that operate on the terms of telephone exchanges. One of the major drawbacks to service development is the lack of controllability of an analog terminal, such as a telephone, from a telephone network. Lack of controllability 15 prevents communication with the terminal without customer response.

The telephone network may be an analogue PSTN (PSTN) (Public Switch Telephone Network) and / or an ISDN (Integrated System Digital Network).

Nationally, standardization of A-subscriber number portability between a telephone exchange and a terminal on a PSTN network is being standardized. The new standard includes codes for implementing standardized services to the terminal. The number of codes is limited, and each new service implemented with the help of codes requires new software for telephone exchanges corresponding to the service in question.

A method for transmitting information over a telephone network between two terminals is known in the prior art, in which method the transmitting subscriber n. DTMF info codes (DTMF, Dual> · · are used instead of mero

Tone Multi-Frequency). When information codes are used, there is a problem in transmitting the code between the call centers of different manufacturers because there are no suitable standardized data elements.

Also known is a method using FSK modem transmission (Frequency Shift Keying, FSK 105519 2 frequency modulation). The FSK modem transfer is not yet available in PBXs and this transfer does not solve the dial-up signaling problem.

The object of the invention is to eliminate the drawbacks mentioned above. In particular, it is an object of the invention to provide a method in which terminals can communicate over a telephone network without immediate action by the receiving terminal. It is a further object of the invention to provide a method where different services can be provided between two terminals without modifications to the telephone exchange.

In the method of the invention, messages are transmitted between terminals in a telephone network. The Pu-15 dial-up network includes a telephone exchange with subscriber lines. The terminal belonging to the telephone network is connected to a subscriber line. The subscriber number of the transmitting terminal, A-subscriber number, is transmitted over the telephone network to the receiving terminal, B-20, to the subscriber terminal.

The transmitting terminal according to the invention may be a server-type computer for controlling terminals via messages and a telephone network and storing in the memory typical server-specific software which may be transmitted to the terminals, inter alia. The terminal may be a computer equipped with a suitable telephone network modem and software. The software on the servers can be used to modify the message sent to the terminals. 30 The terminals recognize the message generated by the server.

According to the invention, a message on the server is added to the code field of the A-subscriber number. The message code field includes the server type and / or control size 35 di. The modified A subscriber number is sent to the server's subscriber line, from where it is forwarded over the telephone network to the terminal. The message can be used to control the terminal 3 105519. The control may be, for example, that the terminal displays some information based on the control code on its display.

In one embodiment of the method, the server 5 disconnects from the telephone network when the modified w A subscriber number is transmitted to the B subscriber.

In one embodiment of the method, the terminal recognizes different control codes and operates on the basis of the wedding. The method enables information to be sent to 10 terminals and to implement a variety of sales services, such as the sale of road computer programs over a telephone network.

In one embodiment of the method, the server sends an information to the terminal informing, for example, the amount of the telephone bill at a given time.

In one embodiment of the method, the terminal receives information from the server, based on which the terminal opens a connection to the server. In this case, new features can be updated to the terminal.

Thanks to the invention, communication between the server and the terminal operates over a telephone network without answering at the terminal. The server can thus control the terminal in many ways.

Furthermore, the invention makes it possible to provide various services between the server and the terminal without modifications to the telephone exchange using a nationally standardized A-subscriber number transfer feature.

The invention enables a secure connection of the server to the terminal, since the A-subscriber number * 'cannot be transmitted to the telephone network from a server outside the network other than the operator, and the subscriber number of the telephone exchange interface cannot be modified.

35 from the junction.

In the following, the invention will be described in more detail by way of application examples with reference to the accompanying drawing 4 105519, which illustrates an embodiment of the method of the invention.

The system shown in the figure includes an answering service 1 which is connected to a subscriber interface of a telephone exchange 2 in a telephone network 2. Similarly, the terminals 3a, 3b are connected to the PBX subscriber connections. The telephone exchanges mentioned above may be different telephone exchanges. The terminal 3a is a special wood ringtone which recognizes and displays on its display a message received in a modified 10 A subscriber number. The terminal 3b is a computer which is connected to the telephone network by means of suitable accessories and software.

The voicemail server 1 in the figure calls the subscriber line 15 in the telephone exchange of the telephone network 2, setting the converted A subscriber number to the caller's number. The changed caller ID can be of the form <ZZZZ XXXX 020280>. The character part ZZZZ indicates the server type. The XXXX character code represents the control code and the numeric element is the official domain name of the server. Thus, the Oh-20 partition code is a certain four-character combination containing certain information. After the caller's modified A-subscriber number is transferred, server 1 can immediately disconnect the call. The subscriber number can be transferred over the telephone network via the YKM channel, or common channel signaling channel 25.

'· The terminal 3 receives the A subscriber number transmitted by the server 1 and recognizes that the A subscriber number has come from the voicemail server 1 based on the character part ZZZZ. The terminal 3 recognizes the control code XXXX from the character portion of the A-30 subscriber number. Information based on the control code can be displayed on a display equipped with the terminal 3. The incoming information may also control the operation of the terminal 3 such that the terminal 3 opens a line to the server 1, 35 sends an acknowledgment to the server 1 and / or issues a ring tone.

Some software is updated to the terminal 3b in the following manner. The answering machine 1 has been informed that the terminal 3b wants a software update. The server 1 thus transmits a customized 5 Δ subscriber number to the terminal 3b, where the subscriber number contains information based on the control code for providing a software update. The terminal 3b detects the information and opens a line, followed by a software update from the server 1 to the terminal 3b.

The invention is not limited only to the above exemplary embodiment, but many modifications are possible within the scope of the inventive idea defined by the claims.
