The step of determining that the access instruction meets the preset condition is: and determining that the access instruction is a PBC access instruction configured by a wireless fidelity protection setup (WPS) key.
And selecting an SSID as a default SSID according to a preset rule.
The selecting an SSID as a default SSID according to a preset rule includes:
the sum of the flow of the access users of the SSIDs is counted to obtain the total flow corresponding to the SSIDs; and selecting the default SSID according to the total flow corresponding to each SSID.

The first embodiment is as follows:
the invention is realized by the following steps: the method comprises the steps that a device to be accessed (STA) and a wireless router both support a WPS PBC mode, the wireless router receives that a User configures a plurality of SSIDs on a Web User Interface (Web UI), and the wireless router provides a software Interface to enable the User to configure whether the WPS is enabled or not under each SSID.
Fig. 2 is a flowchart of an embodiment of the method of the present invention, wherein the access method shown in fig. 2 includes the following steps:
step 201: the wireless router writes the configuration information into a storage area;
and the wireless router provides a software interface for receiving the maximum number of users allowed to access and the SSID supporting WPS PBC, which are corresponding to each SSID in the router and configured by the user on the Web UI. In addition, the wireless router counts the number of Wi-Fi actual access users which are connected with each SSID at present and the real-time flow of the users.
In this embodiment, the wireless router writes configuration information such as the number of allowed access users corresponding to each SSID, an SSID supporting WPS PBC, the number of actual access users, and traffic into a non-volatile memory (NV).
Once data is written into NV, the data cannot be lost even if power is lost, and the original setting can still be kept when the data is restarted next time.
Step 202: when the wireless router detects that the WPS PBC is triggered, starting a timer;
step 203: receiving an access instruction of a terminal to be accessed within the time of a timer;
preferably, it is determined whether the access command is a PBC command, and if the access command is determined to be a PBC command, step 204 is executed. Wherein, the PBC instruction refers to a hard key or soft key trigger signal from a terminal to be accessed.
Step 204: inquiring NV WPS configuration information, and selecting an SSID supporting PBC according to the configuration information;
step 205: and judging whether the actual Wi-Fi user access number of the SSID reaches the maximum number of allowed users, if so, turning to step 206, and if not, turning to step 207.
Step 206: increasing the maximum number of users allowed to be accessed corresponding to the current default SSID;
in this embodiment, there are two cases in step 206:
when the sum of the maximum number of users allowed to be accessed and configured by all SSIDs of the router is smaller than the maximum number of users allowed to be accessed by the router, directly increasing the maximum number of users allowed to be accessed and corresponding to the current default SSID;
preferably, in the case that the sum of the maximum number of users allowed to access configured by all SSIDs of the router is equal to the maximum number of routers allowed to access, the step further includes: detecting whether the actual user access number of other SSIDs reaches the corresponding maximum number of allowed users; and if the SSID which does not reach the maximum number of the users allowed to access is detected, reducing the maximum number of the users allowed to access corresponding to the SSID. And updating the adjusted configuration parameters to NV.
Step 207: and accessing the terminal to be accessed to the current default SSID.
In the access process, the routing device completes the access process through encryption authentication with the STA.
And inquiring the maximum user access number NV of the Wi-Fi by the Web UI of the wireless router, updating the maximum user access number NV to the Web UI for display, and finishing WPS encryption by the STA and the wireless router.
Example two
Fig. 3 is a flowchart of an embodiment of the method of the present invention, wherein the access method shown in fig. 3 comprises the following steps:
step 301: the wireless router writes this configuration into the software NV.
The wireless router provides a software interface to accept the user to set WPS enabling a plurality of SSIDs on the Web UI, configure the maximum number of users connectable under each SSID, and write NV.
And the wireless router counts the number of the actual access users connected at present under each SSID and the flow of the access users under each SSID, and writes the real-time counted number into NV.
Optionally, the counted flows of the access users under the SSIDs are summed to obtain a total flow of each SSID, and the total flow is written into the NV.
Step 302: when the wireless router receives a WPS PBC instruction of a terminal to be accessed, inquiring an SSID supporting the WPS PBC according to WPS configuration information of NV;
the PBC instruction refers to a hard key or soft key trigger signal from a terminal to be accessed.
Step 303: and the wireless router determines one SSID as a current default SSID from the SSIDs supporting the WPS PBC according to a preset rule.
The preset rule mode one: and the STA is accessed to the WPS PBC SSID with the least users, so that the number of Wi-Fi access users under each SSID is properly and uniformly managed.
A second preset rule mode: the STA is accessed into the WPS PBC SSID with the minimum total flow of the current access terminal, and user experience is improved.
In the embodiment, two preset rules are only given by way of example, and the invention is not limited to this.
In this embodiment, the step of determining the current default SSID according to the preset rule is optional, and there are other alternative technical solutions: if any SSID supporting the WPS PBC mode is directly enabled is the current default SSID.
Step 304: and when the actual number of the access users of the current default SSID reaches the maximum number of the corresponding allowed access users, jumping to step 305.
Step 305: and increasing the maximum number of allowed users corresponding to the current default SSID or enabling other WPS PBCCSSIDs and accessing the terminal to be accessed to the current default SSID.
The process of increasing the maximum number of users allowed to access corresponding to the current default SSID is the same as the above embodiment, for example: the wireless router adds 1 to the maximum number of users allowed to access the current default SSID, and subtracts 1 from the maximum number of users allowed to access the PBC mode-supporting SSID. And the maximum number of users allowed to access the two SSIDs is updated to the software NV, and the Web UI of the wireless router reads the software NV again to display the configuration information on the Web UI. Compared with the prior art, the method of the invention improves the access of STA to proper SSID by using WPS PBC for the router with multiple SSIDs, and improves the connection success rate of WPS PBC mode. And the Wi-Fi access equipment can be accessed to any SSID of the multi-SSID wireless router, and WPS access users are uniformly summarized under a certain SSID of the wireless router for convenient management.
The step of enabling other WPS PBC SSIDs comprises the following steps:
when the SSID2 and the SSID3 both enable WPS PBC, if the number of the SSID2 actually accessing users reaches the corresponding maximum number of allowed access users, the STA is directly accessed to SSID3.
Preferably, when the SSID2 or other SSIDs have multiple SSIDs and can also access the user, the SSID with the largest difference between the maximum number of users allowed to access and the actual number of users accessed is selected, so that the maximum number of users allowed to access corresponding to the SSID is reduced.
The technical scheme of the embodiment is not limited to the WPS PBC mode, and is also applicable to the case that the user accesses the wireless router in the hotspot searching mode.
By adopting the technical scheme in the embodiment, if the number of the actual access users of all the SSIDs reaches the maximum number of the corresponding allowed access users, the user access fails; as long as the SSID with the number of the actual access users not reaching the maximum number of the corresponding allowed access users exists, the successful access of the users can be ensured.
