Abstract
The disclosure is related to a method of selecting one of access points based on multiple quality parameters in different frames. The method may include receiving a probe response frame from access points, analyzing quality parameters included in the received probe response frame to estimate wireless link quality of each access point, and selecting one of the access points based on the analysis result.
Claims21
A method of selecting one of a plurality of access points by user equipment in a wireless local area network, the method comprising:
- receiving a probe response frame from a plurality of access points;
- performing a first analysis process for analyzing quality parameters included in the received probe response frame to estimate wireless link quality of each access point;
- selecting candidate access points from the plurality of access points based on the analysis result;
- transmitting a query frame of a predetermined standard protocol to the selected candidate access points;
- performing a second analysis process for analyzing information included in response frames received from the candidate access points in response to the query frame of the predetermined standard protocol;
- and
- selecting one from the candidate access points based on the result of the second analysis process.
A method of selecting one of access points by user equipment in a wireless local area network, the method comprising:
- analyzing quality parameters included in a probe response frame received from a plurality of access points to estimate wireless link quality of each access point;
- selecting candidate access points from the plurality of access points based on the analysis result;
- repeatedly transmitting a link quality measurement request frame to the selected candidate access points at a predetermined interval for predetermined times;
- receiving at least one link quality measurement response frame from the selected access points in response to the link quality measurement request frames;
- and
- selecting one of the candidate access points based on information in the received link quality measurement response frame.
