Abstract

The invention relates to an arrangement and method for establishing and maintaining a connection between users'communication devices via a public data network. Communication devices (MSA, MSB) belonging to users of a system are terminals of a telecommunicationnetwork, say mobile phones, and, in addition, they are adapted tomake a link to a data network (210) via a wireless transfer system. Interfaced with the data network there is at least one server (220) that keeps a register of communication devices. A communication device brought near a data network terminal (DTA, BTB) reports itself to the server using a device-specific identifier. This reporting message also contains network address of said terminal.When a connect request arrives from a communication device via a terminal, the server provides for necessary network connection ifthe called device specified in the connect request can be reached. The connection may be a speech connection, for example. The server also draws conclusions about relative locations of terminals.On the basis of such 'mapping' it makes, if possible, a handover from a terminal on the connection route, if the communication device moves during a connection so that the quality of the link between it and the terminal becomes significantly worse. The telecommunication network, the terminals of which the communication devices are, can also be used in the arrangement of a data network connection and also as a spare route for connections.

Claims

17AMENDED CLAIMS[received by the International Bureau on 20 August 2002 (20.08.02); original claims 1-24 replaced by amended claims 1-23 (4 pages)]Claims
1. An arrangement for establishing and maintaining a connection between communication devices via a data network, comprising at least one server interfaced with the data network and data network terminals having network addresses, said server keeping a communication device register, a communication device and a terminal being arranged to establish a data transfer link between each other, characterized in that
- each communication device is arranged to report itself by sending via said data link a certain identifier, as well as to send a call via said data link, - each terminal is arranged to send to the server an identifier received from a communication device and at the same time its own network address, and to notify a communication device about a call received from the server,
- the server has a register for storing identifiers of reported communication devices and network addresses of terminals for the purpose of finding out the reachability of communication devices,
- the server is arranged to send network address of a terminal to another terminal in order to establish a network connection between the terminals, and
- the server is arranged to draw conclusions about relative locations of terminals for making a handover between terminals during a connection between communication devices.
2. An arrangement according to claim 1, characterized in that said communication device is a mobile station.
3. An arrangement according to claim 1, characterized in that said terminal is a PC-type computer.
4. An arrangement according to claim 1, characterized in that said terminal is a hub.
5. An arrangement according to claim 1, characterized in that said terminal is a device in the category of entertainment electronics.
6. An arrangement according to claim 1, characterized in that for said data link, both the terminal and the communication device have Bluetooth units.
7. An arrangement according to claim 1, characterized in that for said data link, the communication device has a transceiver unit according to a wireless LAN technology. 18
8. An arrangement according to claim 1, characterized in that said data network is the Internet.
9. An arrangement according to claim 1, characterized in that said identifier is a telephone number associated with the communication device.
10. An arrangement according to claim 1, characterized in that said identifier is the IMEI code of the communication device.
11. An arrangement according to claim 1, characterized in that said identifier is a code chosen by a user of the communication device.
12. An arrangement according to claim 2, characterized in that at least one ter- minal is arranged to give its geographical coordinates to the server in support of said conclusions about relative locations of terminals.
13. An arrangement according to claim 1 where said communication devices are terminals of a telecommunication network, characterized in that the communication devices are arranged to use said telecommunication network to establish a data network connection and/or as a spare route for the data network transferring data.
14. An arrangement according to claim 14, characterized in that said establishment of a data network connection comprises a transfer of network addresses of data network terminals via said telecommunication network.
15. An arrangement according to claim 1, characterized in that at least one ter- minal is at the same time a server.
16. A method for establishing and maintaining a connection between a first and second communication device via a data network interfaced with at least one server keeping a register of communication devices, and data network terminals having network addresses, which first communication device has a data link to a first ter- minal, and in which method identifiers sent by terminals, referring to users of communication devices, and network addresses of terminals are stored in the server's register, characterized in that
- a call addressed to the second communication device is sent from the first communication device to the first terminal, - a connect request is sent from the first terminal to the server on the basis of said call, 19
- reachability of the second communication device is examined on the basis of information stored in the register of the server,
- it is arranged so that the first and second terminals get each other's network addresses if the second communication device can be reached through said second terminal,
- the call addressed to the second communication device is sent from the server to the second terminal,
- said call is further sent from the second terminal to the second communication device, - an answer to the call is transferred from the second communication device to the first communication device via the route: second terminal, data network, first terminal, first communication device, and
- conclusions are drawn about relative locations of terminals for making a handover between terminals during a connection between communication devices.
17. A method according to claim 16, characterized in that said handover from the terminal serving a communication device is made if the quality of the data link between these two devices drops down to a predetermined level and there exists according to the information stored at a server another terminal through which the connection between communication devices can be maintained.
18. A method according to claim 16, characterized in that to provide the network addresses to the terminals, the network address of the second terminal is sent from the server to the first terminal, and the network address of the first terminal is sent from the server to the second terminal.
19. A method according to claim 16, characterized in that to provide the network addresses to the terminals, the network address of the second terminal is sent from the server to the first terminal, and the network address of the first terminal is sent from the first terminal to the second terminal.
20. A method according to claim 16, characterized in that to provide the network addresses to the terminals, the network address of the first terminal is sent from the server to the second terminal, and the network address of the second terminal is sent from the second terminal to the first terminal.
21. A method according to claim 17, characterized in that said information stored at the server for making a handover between terminals comprise a map of locations of terminals. 20
22. A method according to claim 16, characterized in that said network addresses are altered in order to make external tracking more difficult.
23. A method according to claim 22, characterized in that a way to alter network address is varied according to the time of the day.
