Claim:
1. A method of selecting one of access points by user equipment in a wireless local area network, the method comprising: receiving a probe response frame from 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 access points based on the analysis result; determining whether each of the candidate access points supports a predetermined standard protocol; when the predetermined standard protocol is supported, transmitting a query frame of the predetermined standard protocol to the selected candidate access points, wherein the query frame excludes a probe request frame; receiving a response frame of the predetermined standard protocol from the selected candidate access points, wherein the response frame excludes a probe response frame; performing a second analysis process for analyzing quality parameters based on information included in the received response frame to estimate wireless link quality of each of the selected candidate access points; and selecting one from the selected candidate access points based on the analyzing result.
