US 10,219,203 B2 · Wireless local area network scanning method and wireless access point

Abstract

A wireless local area network scanning method and a wireless access point are provided. The method includes receiving, by a first wireless access point, a probe request frame broadcast by a station and obtaining, by the first wireless access point according to the probe request frame, an SSID associated with the station. Additionally, the method includes rejecting, by the first wireless access point, to reply to the station with a probe response frame corresponding to an SSID different from the SSID associated with the station, or if a preset condition is met, rejecting, by the first wireless access point, to reply to the station with a probe response frame corresponding to an SSID different from the SSID associated with the station.

Dependent claims

A method, comprising:

receiving, by a first wireless access point, a probe request frame sent by a station, wherein a transmitter address in the probe request frame is a medium access control (MAC) address of the station, a basic service set identifier (BSSID) in the probe request frame is a wildcard BSSID, and a service set identifier (SSID) in the probe request frame is a wildcard SSID;
querying, by the first wireless access point according to the MAC address of the station, a mapping relationship between a MAC address set and an SSID set, to obtain the SSID associated with the station, wherein the SSID set comprises a plurality of SSIDs of the first wireless access point;
and
replying, by the first wireless access point, to the station with a first probe response frame corresponding to the SSID associated with the station, wherein the SSID associated with the station is the only SSID of the SSID set that corresponds to a probe response frame that is sent to the station in response to the probe request frame.

A non-transitory computer readable storage medium storing a program for execution by a processor of a wireless access point, the program including instructions to:

receive a probe request frame sent by a station, wherein a transmitter address of the probe request frame is a medium access control (MAC) address of the station, a basic service set identifier (BSSID) in the probe request frame is a wildcard BSSID, and a service set identifier (SSID) in the probe request frame is a wildcard SSID, and wherein the wireless access point is a first wireless access point;
query, according to the MAC address of the station, a mapping relationship between a MAC address set and an SSID set, to obtain the SSID associated with the station, wherein the SSID set comprises a plurality of SSIDs of the wireless access point;
and
reply to the station with a first probe response frame corresponding to the SSID associated with the station, wherein the SSID associated with the station is the only SSID of the SSID set that corresponds to a probe response frame that is sent to the station in response to the probe request frame.
