Description
Technical Field
The embodiment of the application relates to the field of communication, in particular to a connection method, a connection device, a connection system, an electronic device and a computer-readable storage medium.
Background
In a home use scenario of an Optical Network Unit (ONU), a wireless terminal (STA, Station) generally accesses to the Internet directly through a Wireless Local Area Network (WLAN) hotspot of the ONU itself, and a networking situation is as shown in fig. 1, but on one hand, because the ONU manufacturer is limited by cost, the ONU does not have an external antenna, so that a WLAN signal of the ONU is poor; on the other hand, the performance of the operator is more stressed, and it is desirable that the sale router (i.e., access point) can be bundled in addition to selling the ONUs, so the WLAN signal of the purchased ONUs is poor. For the above two reasons, many users install two devices, namely, an ONU and an AP (i.e., a router with a WLAN) at the same time in their homes, and the AP accesses the internet through a Local Area Network (LAN) interface of the ONU, and the networking situation is shown in fig. 2.
In order to improve the coverage of the WLAN network, the actual physical distance between the ONU and the AP is usually relatively long, so as to achieve the purpose of making up for the lack of coverage of the other party. Because the ONU has insufficient WLAN coverage, when the STA is located a little far away from the ONU, the signal quality of the WLAN network to which the STA is connected is poor, which is likely to cause complaints. In the same place, the signal quality of the AP may be better, but due to the design mechanism of the STA itself, the ONU is not necessarily abandoned and associated with the AP.

1. the WLAN module on the AP reports WLAN information such as BSSID, a channel, SSID name and the like to a DHCP module on the local machine, and is mainly used for subsequently reporting the WLAN information of the AP to the ONU through a DHCP message;
2. in a DHCP interaction stage, a DHCP module of the AP transmits WLAN information (BSSID, channel, SSID name and the like) of the AP to a DHCP module of the ONU through an option60 field, and then the subsequent ONU can acquire the WLAN information of the AP;
3. after receiving the DHCP message of the AP, the DHCP module of the ONU analyzes the option60 field, extracts WLAN information (BSSID, channel, SSID name and the like) reported by the AP and reports the WLAN information to the WLAN module of the ONU;
4. after receiving the WLAN information of the AP sent by the DHCP module of the ONU, the WLAN module of the ONU records the WLAN information for subsequent measurement which is possibly initiated;
5. the WLAN module of the ONU initiates periodic detection to detect whether STA is accessed;
if the access exists, step 6 is to obtain a first signal quality evaluation index of the STA;
if not, waiting for detection;
6. the ONU acquires a first signal quality evaluation index of the STA, and mainly focuses on the RSSI.
If the first signal quality evaluation index is continuously smaller than a first preset threshold value for a period of time, the ONU triggers the STA to measure 11k of the AP, namely the ONU sends an 11k measurement request to the STA; wherein the 11k measurement request includes WLAN information; the STA measures the AP by 11k to obtain a second signal quality evaluation index; the STA returns 11k measurement response to the ONU; wherein 11k measurement responses include: a second signal quality evaluation indicator; entering step 7;
and if the first signal quality evaluation index is continuously larger than or equal to the first preset threshold value, no next action is taken, and only the periodic detection is continued.
7. If the difference between the second signal quality evaluation index when the STA is connected with the AP and the first signal quality evaluation index when the STA is connected with the ONU is larger than a second preset threshold, the ONU performs further processing according to the condition whether the STA supports 11 v:
if the STA does not support 11v, canceling the authentication (DEAUTH) of the STA, and simultaneously pulling into a blacklist for a certain time;
if the STA supports 11v, a BSS Transition Management (BTM) Request (BTM Request) is initiated, WLAN information of the AP is notified to the STA, the STA is guided to access the AP, and the STA returns a BTM response (BTMResponse) to the ONU.
