Abstract

The invention relates to a method for transmitting position data to a receiver, wherein a target whose position data is determined, as well as a receiver of position data are selected. The method comprises the steps of generating a request to determine position data, determining the position of the target, and transmitting the position data to the receiver. Information about the receiver is transmitted in connection with the request to determine position data. The message format available for the message to be transmitted to the receiver is determined, and a message complying with the determined message format is generated, to which the position data is added or included. The message including the position data is transmitted to the receiver. The invention also relates to a system, a device, and a computer program product in which the method is applied.

Claims

1. A method for transmitting position data to a receiver, comprising:

selecting a target whose position data is to be determined, as well as a receiver for the position data;

generating a request to determine position data;

transmitting data about said receiver in connection with said request;

determining the position of the target;

determining the message format available for messages to be transmitted to the receiver;

generating a message complying with the determined message format and provided with the position data; and

transmitting the message including the position data to the receiver.

2. The method according to claim 1, comprising performing the selection of the target in the device in which at least one application is being executed, wherein a positioning request supplemented with data about the receiver is transmitted by the application.

3. The method according to claim 2, comprising determining the message format available for messages to be transmitted to the receiver elsewhere than in said application which transmitted the positioning request.

4. The method according to claim 3, wherein the determined position data is left untransmitted to said application.

5. The method according to claim 1, comprising defining at least one address for the receiver;

and determining the message format available for messages to be transmitted to the receiver on the basis of the format of an address defined for the receiver.

6. The method according to claim 1, comprising transmitting also other information in addition to said receiver data in connection with the positioning request.

7. The method according to claim 6, comprising using data about one or more methods available for determining the position of the target as said other information.

8. The method according to claim 1, comprising transmitting also other information in the message including the position data.

9. The method according to claim 8, wherein said other information comprises at least one of the following items:

information about the target whose position data is transmitted in said message, such as an individual identification, a pseudonym and/or an anonymity description of the target;

data about the quality of the position data, such as the accuracy/inaccuracy of the positioning.

10. A system comprising:

a device with means for selecting a target, and means for generating a request to determine position data;

means for determining the position of the target;

means for transmitting data about said receiver in connection with the request to determine position data;

determining means for determining the message format available in messages to be transmitted to the receiver;

message generating means for generating a message complying with the determined message format, supplemented with the position data; and

a transmitter for transmitting the message including the position data to the receiver.

11. The system according to claim 10, said device comprising means for executing at least one application, wherein a positioning request, supplemented with information about the receiver, is transmitted from the application.

12. The system according to claim 11, wherein said determining means are located elsewhere than in said application which transmitted the positioning request.

13. The system according to claim 10, wherein at least one address is defined for the receiver;

and that the message format available for messages to be transmitted to the receiver is determined on the basis of the format of an address defined for the receiver.

14. The system according to claim 10, comprising positioning means;

message interpreting means; and

a data transmission network for the transmission of messages.

15. The system according to claim 14, wherein said positioning means and message interpreting means are separate from the device, wherein the positioning request is transmitted from the device to the positioning means;

and the data about the receiver is transmitted to the interpreting means; and

the determination of the message format available for messages to be transmitted to the receiver and the transmission of the position data to the receiver are performed in the interpreting means.

16. The system according to claim 14, wherein said device comprises said positioning means and message interpreting means, wherein the positioning request is transmitted from an application being executed in the device to the positioning means;

and the data about the receiver is transmitted to the interpreting means; and

that the determination of the message format available for messages to be transmitted to the receiver and the transmission of the position data to the receiver are performed in the interpreting means.

17. A device comprising:

means for selecting a target;

means for generating a request to determine position data and for transmitting it to positioning means to determine the position of the target;

means for transmitting the position data to a receiver, wherein the data about said receiver is transmitted in connection with the request to determine position data;

determining means for determining the message format available for messages to be transmitted to the receiver;

message generating means for generating a message complying with the determined message format and supplemented with the position data; and

a transmitter for transmitting the message including the position data to the receiver.

18. A program which comprises machine-executable program instructions for:

transmitting position data to a receiver;

selecting a target whose position data is to be determined;

selecting a receiver for the position data;

generating a request to determine position data;

transmitting data about said receiver in connection with the request to determine position data;

determining the position of the target;

determining the message format available for messages to be transmitted to the receiver;

generating a message complying with the determined message format;

including the position data in said message; and

transmitting the message including the position data to the receiver.

19. A storage means for storing a program, which program comprises machine-executable program instructions executable by a processor for:

transmitting position data to a receiver;

selecting a target whose position data is to be determined;

selecting a receiver for the position data;

generating a request to determine position data;

transmitting data about said receiver in connection with the request to determine position data;

determining the position of the target;

determining the message format available for messages to be transmitted to the receiver;

generating a message complying with the determined message format;

including the position data in said message; and

transmitting the message including the position data to the receiver.
