Abstract

The invention relates to a method of operating a cognitive radio device (100), particularly a mobile terminal, which is capable of establishing radio communications with a further radio device, particularly a base station of a communications network and/or a further mobile terminal.

The inventive method is characterized by:

• • providing a communication parameter database (110) local to said cognitive radio device (100), wherein said communication parameter database (110) comprises communication parameters related to geographic locations,
  • determining a geographic location of said cognitive radio device (100), and by
  • choosing one or more communication parameters for a future radio communication depending on said communication parameter database (110) and the determined location of the cognitive radio device (100).

Claims

1. Method of operating a mobile cognitive radio device (100), particularly a mobile terminal, which is capable of establishing radio communications with a further radio device, particularly a base station of a communications network and/or a further mobile terminal, characterized by:

providing a communication parameter database (110) local to said mobile cognitive radio device (100), wherein said communication parameter database (110) comprises communication parameters related to geographic locations,

determining a geographic location of said mobile cognitive radio device (100), and by

choosing one or more communication parameters for a future radio communication depending on said local communication parameter database (110) and the determined location of the mobile cognitive radio device (100).

2. Method according to claim 1, characterized in that said communication parameters comprise information on radio frequencies which may or may not be accessed and/or scanned by the cognitive radio device (100).

3. Method according to claim 1, characterized in that said communication parameters comprise information on general frequency spectrum usage.

4. Method according to claim 1, characterized in that said communication parameters comprise information on further radio devices, particularly base stations of a communications network and/or radio access points, and information on frequency ranges and/or air interfaces and/or services related to said further radio devices.

5. Method according to claim 1, characterized by verifying and/or updating the communication parameters of said communication parameter database (110) and/or the geographic location during and/or after a radio communication.

6. Method according to claim 1, characterized in that a plurality of communication parameter databases (110) is provided, each communication parameter databases (110) having specific information related to a geographic region, particularly a country or a continent, and characterized by storing one or more of said communication parameter databases (110) to said cognitive radio device (100).

7. Method according to claim 1, characterized in that said step of choosing comprises:

determining which type of radio communications is possible at the determined location of the cognitive radio device (100),

selecting from said possible types the type of radio communications which fits best, according to predetermined parameters, to a service that is required, e.g. from a user of the cognitive radio device (100).

8. Mobile cognitive radio device (100), particularly a mobile terminal, which is capable of establishing radio communications with a further radio device, particularly a base station of a communications network and/or a further mobile terminal, characterized by comprising a local communication parameter database (110), wherein said communication parameter database (110) comprises communication parameters related to geographic locations, and characterized in that said mobile cognitive radio device (100) is configured to determine its geographic location, and to choose one or more communication parameters for a future radio communication depending on said local communication parameter database (110) and the determined location.

9. Cognitive radio device (100) according to claim 8, characterized by storage means for storing one or more communication parameter databases (110).

10. Cognitive radio device (100) according to claim 8, characterized in that said communication parameters comprise information on general frequency spectrum usage.

11. Cognitive radio device (100) according to claim 8, characterized in that said communication parameters comprise information on further radio devices, particularly base stations of a communications network and/or radio access points, and information on frequency ranges and/or air interfaces and/or services related to said further radio devices.

12. Cognitive radio device (100) according to claim 8, characterized in that said cognitive radio device (100) is configured to verify and/or update the communication parameters of said communication parameter database (110) and/or the geographic location during and/or after a radio communication.

13. Cognitive radio device (100) according to claim 8, characterized in that said cognitive radio device (100) is configured to

determine which type of radio communications are possible at the determined location of the cognitive radio device (100),

select from said possible types the type of radio communications which fits best, according to predetermined parameters, to a service that is required, e.g. from a user of the cognitive radio device (100).
