Wireless network management procedure, station supporting the procedure, and frame format for the procedure
First Claim
1. A method for performing an event reporting service by a wireless station in a wireless local area network system, the method comprising:
- transmitting, by the wireless station to an access point (AP), an association request frame for requesting association with the AP, the association request frame including capability information indicating that the wireless station supports the event reporting service;
receiving, from the AP by the wireless station in response to the association request frame, a second wireless frame including an association response frame including capability information indicating that the AP supports the event reporting service;
logging, by the wireless station, at least one event for the event reporting service based on the association response frame;
receiving, by the wireless station from the AP, a third wireless frame including an event request frame including a category field followed by an action field followed by a dialog token field followed by an event request element field,wherein the event request element field including an event type field followed by an event response limit field, the event type field indicates an event type that is requested to be reported, and the event response limit field indicates an event response limit that is associated with a maximum number of logged events included in an individual event response frame;
transmitting, to the AP by the wireless station in response to receiving the event request frame, a fourth wireless frame including an event response frame including an event report element including at least one logged event selected according to the event type and the event response limit,wherein the event report element is a most recent event corresponding to the event type; and
if the event report element does not fit into a single Medium Access Control Management Protocol Data Unit (MMPDU), transmitting, by the wireless station to the AP, at least one additional wireless frame including a remaining event report element.

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.

4. A method for performing event reporting service via an access point (AP) in a wireless local area network system, the method comprising:
-
receiving, by the AP from a wireless station, a first wireless frame including an association request frame for requesting association with the AP, the association request frame including capability information indicating that the wireless station supports the event reporting service; transmitting, to the wireless station by the AP in response to receiving the association request frame, a second wireless frame including an association response frame including capability information indicating that the AP supports the event reporting service and initiating a logging of at least one event for the event reporting service by the wireless station; transmitting, by the AP to the wireless station, a third wireless frame including an event request frame including a category field followed by an action field followed by a dialog token field followed by an event request element field, wherein the event request element field including an event type field followed by an event response limit field, the event type field indicates an event type that is requested to be reported, and the event response limit field indicates an event response limit that is associated with a maximum number of logged events included in an individual event response frame; receiving, from the wireless station by the AP in response to the event request frame, a fourth wireless frame including an event response frame including an event report element including at least one logged event selected according to the event type and the event response limit, wherein the event report element is a most recent event corresponding to the event type; and if the event report element does not fit into a single Medium Access Control Management Protocol Data Unit (MMPDU), receiving, by the AP from the wireless station, at least one additional wireless frame including a remaining event report element. - View Dependent Claims (5, 6)
