Abstract

The present invention relates to a method and a wireless station for initiating radio resource measurements. A wireless station identifies a need for radio resource measurements by a second wireless station despite there is no association between the wireless station and the second wireless station allowing direct radio communication between said stations. The wireless station initiates a request for radio resource measurements by the second wireless station.

Claims

1. A method in a wireless station for initiating radio resource measurements, said method comprising the steps of:

identifying a need for radio resource measurements by a second wireless station;

initiating a request for radio resource measurements by the second wireless station,

characterized in that there is no association between the wireless station and the second wireless station (STA2) allowing direct radio communication between said stations.

2. The method according to claim 1, wherein said identifying step includes a substep of identifying said second wireless station from the results of a previous radio resource measurement performed by the wireless station itself or performed and reported to the wireless station by a third wireless station.

3. The method according to claim 1, wherein said wireless station transmits the request for radio resource measurements to the second wireless station via at least one intermediate wireless station.

4. The method according to claim 3, wherein said request for radio resource measurements is transparent to said at least one intermediate wireless station.

5. The method according to claim 4, wherein said request for radio resource measurements is encapsulated in a data frame addressed to said second wireless station.

6. The method according to claim 4, wherein said initiating step includes a substep of initiating a tunnel from said wireless station to said second wireless station via said at least one intermediate wireless station and wherein said request for radio resource measurements is transmitted from said wireless station to said second wireless station via said tunnel.

7. The method according to claim 1, wherein said radio resource measurements by the second wireless station involves at least one of analyzing received radio signals and collecting traffic statistics.

8. A wireless station for use in a radio communication system, said wireless station comprising:

identifying means for identifying a need for radio resource measurements by a second wireless station;

initiating means, operable connected to the identifying means, for initiating a request for radio resource measurements by the second wireless station,

characterized in that there is no association between the wireless station and the second wireless station allowing direct radio communication between said stations.

9. The wireless station according to claim 8, wherein said identifying means are adapted to identify said second wireless station from the results of a previous radio resource measurement performed by the wireless station itself or performed and reported to the wireless station by a third wireless station.

10. The wireless station according to claim 8, wherein said initiating means are adapted to initiate transmission of the request for radio resource measurements to said second wireless station via at least one intermediate wireless station.

11. The wireless station according to claim 10, wherein said request for radio resource measurements is transparent to said at least one intermediate wireless station.

12. The wireless station according to claim 11, wherein said request for radio resource measurements is encapsulated in a data frame addressed to said second wireless station.

13. The wireless station according to claim 11, wherein said initiating means are adapted to initiate a tunnel from said wireless station to said second wireless station via said at least one intermediate wireless station and wherein said request for radio resource measurements is transmitted from said wireless station to said second station via said tunnel.

14. The wireless station according to claim 8, wherein said radio communication system is a Wireless Local Area Network.
