Abstract

A method and apparatus for setting up a data communication connection to a mobile terminal (terminal B). The calling terminal (terminal A) sends a connection request to a connecting means in the mobile telecommunications network. The connecting means transmits a paging signal to terminal B. Terminal B responds by originating a call to terminal A so that a connection is set up through the network without passing the connecting means. The content information (e.g. voice data) between the two terminals is sent and received without the extra time delay associated with passing through the connecting means, which occurs when the content information must be sent via the connecting means. Also, the connecting means is used more efficiently, since it is not burdened with receiving, processing, and transmitting a relatively large amount of content information from the many connections established between terminals.

Claims

1. A method for establishing a connection between a first terminal connected to a data communication network and a second terminal connected via a mobile telecommunications network, to the same data communication network, comprising the steps of:

sending a connect request from the first terminal to a node in the mobile telecommunications network;

sending a paging message from the node requesting the second terminal to establish a connection to the first terminal;

initiating, upon receipt of the paging message at the second terminal, the connection between the second terminal and the first terminal by forwarding a data call to the first terminal by the second terminal; and

establishing the connection between the second terminal and the first terminal via data communication between the first and second terminals, the node not participating in the data communication or the data call.

2. The method according to claim 1, wherein the data communication network is a TCP/IP network in which a number of subnetworks are connected to form one overall network, such as the Internet.

3. The method according to claim 1, wherein MAP USSD signalling according to the GSM protocol is used for the paging message.

4. The method according to claim 1, wherein GPRS protocols are used for the paging message.

5. The method according to claim 1, wherein the paging message comprises the address of the first terminal.

6. A method for establishing a connection between a first terminal in a data communication network and a mobile, second terminal, connected via a mobile network to the same data communication network, said data communication network comprising or being connected to a connecting means, the method comprising the steps of:

establishing a connection from the first terminal to the connecting means by forwarding a first data call to the connecting means by the first terminal;

sending a paging message from the connecting means requesting the mobile second terminal to establish a connection to the connecting means;

initiating, upon receipt of the paging message at the second terminal, the connection between the second terminal and the connecting means by forwarding a second data call to the connecting means by the second terminal; and

establishing the connection between the second terminal and the first terminal without requiring continued support by the connecting means for the connection.

7. The method according to claim 6, wherein the connecting means is a computer connected to the data network, and the connection between the first and the second terminal is set up through the connecting means.

8. The method according to claim 6, wherein the first terminal is also a mobile terminal connected to the data network through a mobile telecommunications network.
