Abstract

A method and devices for a mobile person'"'"'s information retrieval where, when the person is moving, on coming closer to a point of destination, defined by him as being interesting, than a specified threshold separation, he will be informed of such a point of interest and, on request, additional data will be presented on it, such as driving instructions or a map.

The person is preferably also offered means with which he can make a call to the phone number of the point of interest presented each time. The person can preferably add by himself new points of interest and select from available points of interest individual or several points of interest on the basis of their class, such as, e.g. restaurants or service stations.

Claims

1. A method for informing a mobile person of geographical points of interest (POI) that are of interest to him with an information retrieval device, comprising

allowing said person to determine with said information retrieval device at least one point of interest he desires and a threshold separation, the threshold separation being at least one of the following variables:

distance and time,

repeatedly monitoring the position of said information retrieval device,

collecting available information on all those points of interest which said person has defined with said information retrieval device as his desired points of interest and which are within said threshold separation from the location of said information retrieval device,

transmitting information about this kind of POI to said information retrieval device, and

informing said person with said information retrieval device of such a point of interest.

3. A method according claim 1 or 2, wherein

points of interest are grouped according to their type into different kinds of classes and a mobile person can define, by means of these classes, one or more points of interest at a time.

4. A method according to claim 1, wherein

the becoming available of the data on the points of interest that are of interest to a mobile user is informed and they are then kept for a specific period of time on display on the information retrieval device during which time, when he so requests, he will be presented additional data on a point of interest.

5. A method according to claim 4, wherein

at the request of a mobile person, said data are stopped being kept on display.

6. A method according to claim 1, comprising

presenting data on a point of interest with said information retrieval device,

the data on said point of interest comprising a phone number, and

allowing said person to initiate a call to said point of interest with means of the information retrieval device.

2. A method for informing a mobile person of a geographical point of interest that is of interest to him with an information retrieval device, comprising

allowing said person to define with said information retrieval device at least one point of interest he desires and a threshold separation, the threshold separation being at least one of the following variables:

distance and time,

repeatedly monitoring the position of said information retrieval device,

collecting available information on all those points of interest which said person has defined with said information retrieval device as his desired points of interest and which are within said threshold separation from the location of said information retrieval device,

transmitting to said information retrieval device its position with a specific accuracy,

searching with said information retrieval device said compiled data for those points of interest which are within said threshold separation from the position of said information retrieval device at the time in question, and

informing said person of such a point of interest.

7. An information retrieval device comprising positioning means for maintaining position data on said information retrieval device, wherein said information retrieval device comprises:

input means for receiving the selection of at least one point of interest that is of interest to the user and at least one criterion of separation from a user of said information retrieval device, the criterion of separation being one of the following variables;

distance and time,

a radio receiver for receiving data on a point of interest (POI) that meets at least one specific criterion of separation,

a memory for storing the received data, and

output means for presenting said data.

8. An information retrieval device according to claim 7, wherein

said positioning means is a satellite positioning device.

9. An information retrieval device according to claim 7, wherein

said positioning means are integrated with other means of the information retrieval device, and

arranged to be receiving with said radio receiver said position data from a mobile communication network or to be determining the position of the information retrieval device with a specific accuracy on the basis of data received from a mobile communication network.

10. An information retrieval device according to claim 7, wherein

said input means are arranged to receive classifications corresponding to the types of the points of interest that are of interest to the user, and

the information retrieval device comprises a radio transmitter for transmitting said classifications on to a mobile communication network for being used elsewhere in order to screen the data on a point of interest to be sent to said information retrieval device according to said classifications.

11. An information retrieval device according to claim 7, wherein

the information retrieval device comprises a mass storage for storing said data.

12. An information retrieval device according to claim 7, wherein

said input means are arranged to receive from the user classifications corresponding to the types of the points of interest that are of interest to the user and

said information retrieval device comprises means for screening the POI data in said memory according to said classifications.

13. An information retrieval device according to claim 7, wherein

said radio receiver is arranged to receive, in addition to said POI data, the position data of the POI,

said information retrieval device comprises means for verifying the meeting of said criterion of separation, and

said output means are arranged to indicate, on the meeting of said criterion of separation, the availability of new POI data to the user, and

said memory is arranged to stop storing said data after a specific time limit from its reception.

14. An information retrieval device according to claim 7, wherein

said information retrieval device comprises

means for storing said data at the request of the user until the user otherwise requests separately, and

means for ending said storing.

15. An information retrieval device according to claim 7, wherein

the data on said point of interest (POI) comprise a phone number,

said memory is arranged to store said phone number, and

the information retrieval device comprises a radio transmitter and means for initiating a call to a point of interest, to be presented with output devices, using the phone number stored in the memory.

16. An information retrieval device according to claim 7 or 13, wherein

said information retrieval device comprises means for indicating an additional information request given by the user, and

means for controlling said output means to present to the user additional data on a POI in response to said indication of the additional information request.

18. A server according to claim 17, wherein

of said criteria, another is the class of a point of interest.

17. A server comprising processing means, for the use of the server being arranged a first database comprising a set of records each having at least one field, and which server comprises data transfer means by means of which it is arranged to be connected to at least one base station of a mobile communication network for transferring at least one field of a record to at least one information retrieval device, wherein
