Abstract

Provided are a WLAN management procedure, a station supporting the procedure, and a frame format for the procedure. In the management procedure, a reporting station receives a event request frame including one or more event request elements each of which comprises an event type field for specifying the event type of an event request and an event response limit field for specifying the number of requested event report elements. And, in response to the event request frame, the reporting station transmits an event response frame including event report elements for the event type specified in the event type field as many as the number specified in the event response limit field.

receiving, in response to the event request frame, an event response frame including event report elements for the event type specified in the event type field as many as the number specified in the event response limit field.

2. The procedure according to claim 1,

wherein each of the event request elements further comprises first event token field containing a unique event token that identifies the event request element within the event request frame, and

wherein each of the event report elements in the event response frame comprises second event token field containing the same event token that is included in one of the event request elements.

3. The procedure according to claim 2,

wherein each of the event request elements further comprises an event request field containing the event request corresponding to the event type specified in the event type field, and

wherein the event type of each of the event request elements is a transition event, a Robust Security Network Association (RSNA), or a peer-to-peer link event.

4. The procedure according to claim 2,

wherein if the event type of an event request element is a system log event, then the event request element does not comprises an event request field.

5. The procedure according to claim 1,

wherein both a requesting STA and a requested STA support an event service and indicate this support using at least one of beacon, association request, association response, re-association request, re-association response, and probe response frames.

6. The procedure according to claim 5,

wherein a destination address field of the event request frame is set to Medium Access Control (MAC) address of the requested STA within the same infrastructure Basic Service Set (BSS) of the requesting STA.

7. The procedure according to claim 1,

wherein all of the event report elements include a status field that indicates the overall result of the event transaction.

8. A wireless network management procedure comprising:

receiving a event request frame including one or more event request elements each of which comprises an event type field for specifying the event type of an event request and an event response limit field for specifying the number of requested event report elements; and

transmitting, in response to the event request frame, an event response frame including event report elements for the event type specified in the event type field as many as the number specified in the event response limit field.

9. The procedure according to claim 8,

wherein each of the event request elements further comprises an event token field containing a unique event token that identifies the event request element within the event request frame, and

wherein each of the event report elements in the event response frame contains the same event token that is included in one of the event request elements.

10. The procedure according to claim 8,

wherein both a requesting STA and a requested STA support an event service and indicate this support using at least one of beacon, association request, association response, re-association request, re-association response, and probe response frames.

11. The procedure according to claim 10,

wherein a destination address field of the event response frame is set to Medium Access Control (MAC) address of the requesting STA.

12. The procedure according to claim 8,

wherein all of the event report elements include a status field that indicates the overall result of the event transaction.

13. The procedure according to claim 12,

wherein the status field in the event report element is set to a value of ‘

Successful’

in case a requested STA is able to return one or more event report elements, a value of ‘

Fail’

in case the request station is unable to process the event request element, a value of ‘

Refuse’

in case the event request element is unacceptable to the requested STA, or a value of ‘

Incapable’

in case the requested STA is incapable of generating an event report element of the event type specified in the event request element.

14. The procedure according to claim 13,

wherein the status field in the event report element is set to a value of ‘

Successful’

, and

wherein the event report element further comprises an event timestamp field containing the time that the event is occurred and an event report field containing the specification of the event report.

15. The procedure according to claim 8,

wherein the transmitted event report frames comprises no event report element in case there is no available event report of the type specified in the event request element.

16. A format for an event request frame which is used for wireless network management, the event request frame comprising:

a category field which is set to a value indicating a wireless network management category;

an action field which is set to a value indicating event request action;

a dialog token field which is set to a nonzero value chosen by a station sending the event request frame to identify the request/report transaction; and

an event request elements field for specifying a request to a station receiving the event request frame to perform the specified actions,

wherein the event request elements field contains one or more event request elements, and

wherein each of the event request elements comprises an event type field for specifying the type of event request, an event response limit field for specifying the number of requested event report elements included in an event response frame which is generated in response to the event request frame, and an event request field for containing the event request corresponding to the event type specified in the event type field.
