The method includes: receiving, by an access point, a probe request sent by at least one station, where the probe request includes an identifier of the access point; determining, by the access point, a first station in the at least one station according to the probe request sent by the at least one station, where the identifier included in the probe request sent by the first station matches an identifier of the access point, and a signal strength of the probe request sent by the first station is greater than a signal strength threshold; and automatically triggering, by the access point, a registrar protocol interaction with the first station. ## Claims ### Claim 1 A method for triggering a registrar protocol interaction used for performing a wireless simple configuration between an access point and at least one station and implemented by the access point, the method comprising: receiving from the at least one station a probe request comprising an identifier of a target access point; matching a first station in the at least one station to the access point based on the identifier of the target access point being equal to an identifier of the access point and based on a signal strength of the probe request being greater than a signal strength threshold; and automatically triggering, in response to the matching and independent of a user identifier, the registrar protocol interaction between the access point and the first station. ### Claim 2 (depends on 1) The method of claim 1, wherein the probe request indicates the signal strength threshold. ### Claim 3 (depends on 2) The method of claim 2, further comprising further matching the first station to the access point based on the signal strength being greater than the signal strength threshold indicated in the probe request. ### Claim 4 (depends on 1) The method of claim 1, further comprising specifying the signal strength threshold. ### Claim 5 (depends on 1) The method of claim 1, wherein automatically triggering the registrar protocol interaction comprises sending to the first station a probe response for the first station to trigger the registrar protocol interaction. ### Claim 6 (depends on 5) The method of claim 5, wherein the probe response comprises the signal strength threshold. ### Claim 7 (depends on 1) The method of claim 1, wherein the identifier of the target access point and the identifier of the access point are the same media access control (MAC) address. ### Claim 8 A method for triggering a registrar protocol interaction used for performing a wireless simple configuration between a station and at least one access point and implemented by the station, the method comprising: sending a probe request to the at least one access point; receiving, from the at least one access point in response to the probe request, a probe response comprising an identifier of a target station and indicating a first signal strength threshold with a numerical value or an identifier; matching a first access point in the at least one access point to the station based on the identifier of the target station being equal to an identifier of the station and based on a signal strength of the probe response being greater than the first signal strength threshold indicated in the probe response; and automatically triggering, in response to the matching, the registrar protocol interaction between the station and the first access point. ### Claim 9 (depends on 8) The method of claim 8, further comprising specifying the first signal strength threshold. ### Claim 10 (depends on 8) The method of claim 8, further comprising: receiving a broadcast message from the first access point; and further sending the probe request in response to a broadcast signal strength of the broadcast message being greater than a second signal strength threshold. ### Claim 11 (depends on 10) The method of claim 10, wherein the probe request comprises: an identifier of the first access point for triggering the registrar protocol interaction; and the first signal strength threshold. ### Claim 12 (depends on 8) The method of claim 8, wherein the identifier of the target station and the identifier of the station are the same media access control (MAC) address. ### Claim 13 (depends on 8) The method of claim 8, further comprising further automatically triggering, independent of a user identifier, the registrar protocol interaction. ### Claim 14 An access point comprising: a memory; a transceiver configured to receive from at least one station a probe request comprising an identifier of a target access point; and a processor coupled to the memory and the transceiver and configured to: match a first station in the at least one station to the access point based on the identifier of the target access point being equal to an identifier of the access point and based on a signal strength of the probe request being greater than a signal strength threshold; and automatically trigger, in response to the matching and independent of a user identifier, a registrar protocol interaction between the access point and the first station. ### Claim 15 (depends on 14) The access point of claim 14, wherein the probe request indicates the signal strength threshold. ### Claim 16 (depends on 15) The access point of claim 15, wherein the processor is further configured to further match the first station to the access point based on the signal strength being greater than the signal strength threshold indicated in the probe request. ### Claim 17 (depends on 14) The access point of claim 14, wherein the processor is further configured to specify the signal strength threshold. ### Claim 18 (depends on 14) The access point of claim 14, wherein the processor is further configured to further automatically trigger the registrar protocol interaction by instructing the transceiver to send to the first station a probe response for the first station to trigger the registrar protocol interaction. ### Claim 19 (depends on 18) The access point of claim 18, wherein the probe response comprises the signal strength threshold. ### Claim 20 (depends on 14) The access point of claim 14, wherein the identifier of the target access point and the identifier of the access point are the same media access control (MAC) address.
