Abstract
The present invention discloses a method of notifying an alert status. The method includes using at least two binary alert status indication fields to indicate alert status information; changing a value of the alert status indication field when alert information is changed; and periodically sending the alert status information. The alert status indication field in a interworking element of a beacon frame is extended so that the status of the emergency alert is detected, the change to the emergency alert status is reflected by the value of the extended alert status indication field, and the change to the emergency alert can be detected and handled in a timely manner.
Claims14
A method of notifying an alert status, comprising:
- indicating alert status information using an alert status indication field that comprises at least two binary bits;
- changing a value of the alert status indication field to one of three or more different values when the alert status information is changed;
- periodically sending the alert status information when the value of the alert status indication field is changed,
- judging whether an alert occurs by a second judging unit;
- setting at least one binary bit that indicates whether the alert occurs or not in the alert status indication field to a second value when no alert occurs and setting the at least one binary bit that indicates whether the alert occurs in the alert status indication field to a third value when the alert occurs by a second setting unit;
- judging whether the alert status information is changed by a third judging unit;
- and
- changing a value of at least one other binary bit that indicates the change to the alert status information based on a judgment result of the third judging unit when the alert status information is changed by a third setting unit.
An access point device, comprising:
- a processing unit configured to change a value of an alert status indication field to one of three or more different values when alert status information is changed, wherein the alert status indication field comprises at least two binary bits;
- and
- a sending unit configured to periodically send the alert status information in a message notifying an alert status when the value of the alert status indication field is changed,
- wherein the processing unit comprises:
- a second judging unit configured to judge whether the alert occurs;
- a second setting unit configured to set the at least one binary bit that indicates whether the alert occurs or not in the alert status indication field to a second value when no alert occurs and set the at least one binary bit that indicates whether the alert occurs in the alert status indication field to a third value when the alert occurs;
- a third judging unit configured to judge whether the alert status information is changed;
- and
- a third setting unit configured to change a value of the at least one other binary bit that indicates the change to the alert status information based on a judgment result of the third judging unit when the alert status information is changed.
