Abstract

In a cellular communications network, text messages, unique for a certain group of base stations (2) at each instant, are broadcast to mobile terminals (6). The mobile terminals (6) include the text message or a text derived based on at least the text message as a part of a position dependent service request data packet. The data packet is sent to a service provider (30). The included text is interpreted, e.g. in the communications system or in the service provider (30), as a position or location associated with the base station (2) group that broadcast the text message. The position dependent service is then provided based on the interpreted position or location.

Claims

1. A method of providing position-based services for terminals in a cellular communications network, the method comprising the steps of:

broadcasting a first text message from a set of base stations of the cellular communications network;

detecting the first text message, in a mobile terminal connected to a base station in the set of base stations;

the first text message being unique for the set of base stations at the broadcasting instant;

creating a data packet comprising a position-based service request;

including a second text message, being dependent on the first text message, in the data packet;

transmitting the service request to a service provider;

associating the second text message with a position connected with the set of base stations; and

providing services based on the service request and the associated position.

2. The method according to claim 1, comprising the further step of providing the first text message as a time dependent first text message.

3. The method according to claim 2, wherein the step of providing the first text message is performed by a pre-determined algorithm.

4. The method according to claim 3, wherein the step of associating is performed in the service provider., whereby the step of transmitting comprises transmitting of the data packet from the mobile terminal to the service provider.

5. The method according to claim 1, wherein the step of associating is performed in a gateway between the cellular communications system and the service provider, whereby the step of transmitting comprises transmitting of the data packet from the mobile terminal to the gateway and transmitting of the service request and the associated position from the gateway to the service provider.

6. The method according to claim 4, comprising the further step of providing association data from the cellular communications system to a node performing the step of associating, whereby the step of associating utilizes the association data.

7. The method according to claim 4, comprising the further step of providing the pre-determined algorithm from the cellular communications system to a node performing the step of associating, whereby the step of associating utilizes the pre-determined algorithm to provide association data.

8. The method according to claim 1, wherein the set of base stations comprises only one base station.

9. The method according to claim 1, wherein the second text message is identical to the first text message.

10. The method according to claim 1, wherein the second text message is created by processing the first text message.

11. The method according to claim 10, wherein the processing is further dependent on an identity associated with the mobile terminal or a user thereof.

12. The method according to claim 1, wherein the data packet comprises a Uniform Resource Locator address in turn comprising the second text message.

13. The method according to claim 1, wherein the step of creating a data packet in turn comprises the steps of running an application software using the first text message or a part thereof as authorization verification.

14. The method according to claim 1, wherein the step of providing services comprises downloading of encoded data and decoding of the encoded data based on the first text message or a part thereof.

15. A system for providing position-based services for terminals in a cellular communications network, the system comprising:

a set of base stations having a transmitter capable of broadcasting a first text message the first text message being unique for the set of base stations at the broadcasting instant;

a mobile terminal connected to a base station in the set of base stations, the mobile terminal comprising;

a receiver capable of detecting the first text message;

a processor arranged for creating a data packet comprising a position based service request;

the processor being connected to the detector, enabling inclusion of a second text message, being dependent on the first text message, in the data packet;

a transmitter capable of transmitting the service request to the service provider via the cellular communications network; and

a service provider node for position-based services, the service provider being arranged for providing services based on the service request and the associated position.

16. The system according to claim 15, further comprising:

means for providing time dependent first text messages.

17. The system according to claim 16, wherein the means for providing time dependent first text messages utilizes a pre-determined algorithm.

18. The system according to claim 17, wherein the means for associating is comprised in the service provider.

19. The system according to claim 15, wherein the means for associating is comprised in a gateway between the cellular communications system and the service provider arranged for forwarding the associated position to the service provider together with the service request.

20. The system according to claim 18, further comprising communication means for providing association data from the cellular communications system to the means for associating.

21. The system according to claim 18, further comprising communication means for providing the predetermined algorithm from the cellular communications system to the means for associating.

22. The system according to claim 15, wherein the set of base stations comprises only one base station.

23. The system according to claim 15, wherein the second text message is identical to the first text message.

24. The system according to claim 15, wherein the second text message is created by processing the first text message.

25. The system according to claim 24, wherein the processing of the first text message is further dependent on an identity associated with the mobile terminal or a user thereof.

26. The system according to claim 15, wherein the data packet comprises a Uniform Resource Locator address in turn comprising the second text message.

27. A node in a communications system, the node comprising:

receiver of a first data packet comprising a second text message;

means for associating the second text message with a position connected with a set of base stations broadcasting a first text message on which the second text message is dependent; and

transmitter of a second data packet comprising the associated position.

28. The node according to claim 27, further comprising a receiver of data associated with the generation of text messages.

29. A service provider node for position-based services, comprising:

a receiver of data packets comprising a position-based service request, the data packets comprising a text message;

means for associating the text message with a position; and

means for providing services based on the service request and the associated position.

30. The service provider node according to claim 29, further comprising a receiver of data associated with the generation of text messages.

31. A mobile terminal for use in a cellular communications network, the mobile terminal comprising:

a receiver capable of detecting a broadcast first text message from a set of base stations to which it is connected;

processor arranged for creating a data packet comprising a position based service request, the processor being connected to the detector, enabling inclusion of a second text message, being dependent on the first text message, in the data packet; and
