A method and system for transferring a call

The invention relates to a method for transferring a call according to the preamble of claim 1.

5

The invention also relates to a system for transferring a call.

According to FI 101663, it is possible to further connect the call received to the terminal to another location after answering. According to said method 10, the user of the answering terminal (human or machine) closes the connection, reconnects now to the receiving device, dials here the numbers indicating the place where the call wants to be connected, closes the data necessary for connecting the telephone.

15 The following weaknesses can be mentioned. The call combiner will have to make a complicated operation and focus on the numbers he or she chooses. This makes pairing so difficult that it is not easy to perform from any phone. A prerequisite for the method is answering the call, so the caller also has to pay for the call during the connection.

20

Shutdown and re-connection control (also known as "flash" in the landline technology) is not possible on existing cellular networks without changing the behavior of the programs that control the networks, since sending the "B-shut" character will immediately disconnect 25 calls.

In practice, the "B-close" character is sent, for example, from a mobile phone by pressing the red telephone handset key, and it is no longer possible to open the same telephone connection.

The method described in said publication does not allow for the method of operation of the method to be used to connect the self-made call, i.e. the outgoing call. · '. in accordance with the. This requires another procedure, and the customer must learn at least 2,108,187 two different ways of working; a first procedure for interconnecting self-made calls and a second procedure for forwarding an incoming call.

The object of the present invention is to overcome the shortcomings of the above-described technology and to provide a completely new type of method and system for transferring a call.

The invention is based on the method employing a data connection unrelated to the call to be connected and its control connection (signaling), which transmits the call control data to a signaling server (typically WEB server) of a non-connected network (e.g. Internet) which in turn transmits them centrally controlled over the telephone network. SCP).

Preferably, the invention makes the combination process and the technique used such that the combination can be accomplished simply with a few operations. This is accomplished by utilizing an end-to-end wireless signaling protocol (WAP or similar) between the terminal unit and the terminal performing the approved telephony connection, transmitting the telecommunication control information to the controlling device using it (typically a WEB server), controlling device 20 (typically SCP) in a format it understands. In addition, the control signaling is transmitted on a separate data path from the actual telephone connection.

25 It is therefore a question of using communications other than normal telephone network signaling on a separate data link from the telephone connection to control the call.

The system according to the invention, in turn, comprises a server connected by a separate communication connection with at least one terminal 30 of the system and a database, the server being able to communicate with the terminal with a signaling different from the signaling of the telephone communication. converting the data received from the terminal to a format understood by the database; and 3 108187 the data obtained from the database to a format understood by the terminal, and thus performs a protocol conversion.

More particularly, the method according to the invention is characterized in that which is set forth in the characterizing part of claim 1.

The ice system according to the invention, in turn, is characterized by what is stated in the characterizing part of claim 9.

The invention provides considerable advantages.

When operating according to the invention, call times or call combining can also be performed in a situation where the call passes over two different network interfaces (for example, an Internet call where the call comes from the Internet and is forwarded to a normal telephone network or vice versa). The connection is also possible from mobile phones or other similar terminals / networks, where the normal telephone connection is terminated when the subscriber closes. The waste system of the invention enables the user to have a menu-based user interface in which call control is effortless.

The invention will now be further explored by way of exemplary embodiments of the accompanying drawings.

Figure 1 is a block diagram of one method according to the invention.

Figure 2 is a block diagram of another method according to the invention.

Connecting an incoming call by answering the call is illustrated in Figure 1.

The call connects from the terminal 1 of the telephone network to the terminal 2 normally. Terminal 1 is typically an SSP exchange with intelligent network functionality. The user of terminal 30 2 answers the call and, upon recognizing the need for connection, selects "connect" and "destination number to connect" from menu 3 of their terminal 2 menu. Menu menu. 3 may include a plurality of pre-stored item numbers, menu 3 may be updated 4 108187 either from terminal 2 or from the network. The terminal 2 sends the information selected from the menu menu 3 to the network server 5 5, which is not connected to the actual call to be connected, which is typically a WEB server. The server 5 forwards the data association to the managing network element 6, in the protocol-controlled form of the element, the network element 6 being typically the database of the intelligent network controller SCP. The controller 6 sends the appropriate control message 7 according to the signaling protocol used to control the telephone exchange of the terminal, which as a result performs the connection 8 to the desired 10 destinations 9. The control message 7 is transmitted after the user 2 terminates the initial connection.

Pressing the B-close button directs the terminal 1 to send call termination information to the network element 6.

15

Thus, the action sequence for controlling a call is as follows: a) Input data, for example, via WAP to control the call.

b) Close the original call or call attempt (this is a call attempt if 20 calls have not been answered at all before the call is diverted).

c) As a result of this (lock), for example, the SCP redirects the call to a new location.

Connecting an incoming call without answering the call is also described below with reference to Figure 1.

25

The call connects from the telephone exchange terminal 1 (typically an SSP exchange with intelligent network functions) to the terminal 2. The user of the terminal 2 decides to connect the call without answering the call, for example because he sees in the caller's number that it is not worth answering the call right now. Operation proceeds as follows: 30 The user selects "connect" and "destination number to connect" from menu 3 of his terminal 2. Menu Menu 3 can contain a number of pre-stored 5,108,187 destination numbers, and the menu can be updated either from the terminal or from the network (the former takes place in a manner acceptable to the terminal, for example, via WAP or SMS).

The terminal 2 sends the protocol 4 to the network server 5, which is typically a WEB server, which is not connected to the actual call to be connected, serving the protocol 4. The server 5 forwards the data association to the managing network element 6, in the form of protocol controlled by the element, which is typically a database of an intelligent network controller (SCP).

10

Thus, the server 5 is connected via a communication link to one or more databases 6 and the communication link between the terminal and the server 5 is opened by the controls according to the signaling protocol used each time the user of the terminal performs controls from his menu. The server 5 is capable of communicating with the terminal 2 with a signaling 15 different from the signaling used for telephony control, and converting the information received from the terminal 2 into a format understood by the database 6 and a data obtained from the database 6.

When the user of the terminal 2 terminates the connection by pressing the "B-close" button, this information is transmitted 20 via a standard telephone network signaling connection from the terminal 1 to the controller 6. Based on the unloading information and previously obtained connection information through the server 5, the controller 6 establishes and transmits a control message 7 according to the signaling protocol used, to the exchange 1, which as a result performs the connection 8 to the desired destination 9.

25

If the charge for the call is based on the time of the answer, as is currently the case in the telephone network, the call charge for the caller will only be triggered when the new destination 9 of the call answers the call.

A method for connecting two separately taken outgoing calls is shown in connection with Figure 2.

6 108187

As shown in Figure 2, the first call is normally established between the terminal 11 and the terminal 12 of the telephone network. Terminal 12 is typically an SSP exchange with intelligent network functionality. The call is routed to the dialed number to which the B-subscriber terminal 20 is connected.

5 The user of terminal 11 decides to take another call, selects "connect" and "destination number to connect" from menu 13 of his terminal. Menu Menu 13 may include a plurality of pre-stored item numbers, and may be updated either from the terminal or from the network. The update from the terminal 10 takes place in a manner approved by the terminal 11, for example, via WAP protocol or SMS.

The terminal 11 sends the information 14 to the network server 15, which is not connected to the actual call to be connected, serving the protocol 14. The server 15 15 is typically a WEB server which forwards the data combining to the network element 16. The network element is typically an intelligent network controller (SCP) database.

Controller 16 sends a proper control message 17, corresponding to the signaling protocol used, to exchange 12, which as a result performs a connection 18 20 to a desired second destination 19 to form a second call.

When the call is set up at another destination 19, this is communicated to the network element 16 carrying out the connection using the protocol 21 used for normal telephone connection signaling.

Receiving 25 '' Connected '' information 21 (which actually means '' numbers arrive ''), '' Call set-up '' or similar message in controller 16 causes the following actions:

Connection information 22 is transmitted to the non-connected server 15, the server 15 forwards the information to the menu 13 of the terminal 11 using the protocol used, whereby the user of the terminal 11 receives the connection information. This information may be conveyed graphically, for example, by means of the text '' Combined '' or other appropriate 7 108187 'Tcuvalogon'. Alternatively, information may be transmitted such that the terminal generates a tone or music, etc. Controller 16 sends control message (s) 23 to exchange 12, whereupon the exchange 12 disconnects the exchange 12 with the first call terminal 5 and the second call terminal. 19 connections.

Within the scope of the invention, the Item Number can be freely selected instead of the number entered in the ready menu.

10 If the menu information of the user terminal is updated from the network, the user may be depicted with the ability to update the stored information on the network, for example, via an Internet connection, of course, backed up by normal data security means.
