In the embodiment of the present invention, the coverage hole detection method is applied to the coverage hole detection system 10 shown in fig. 1, and specific flows and steps of the coverage hole detection method shown in fig. 2 are described in detail below.
In the embodiment of the invention, the method for detecting the coverage loophole comprises the following steps:
in step S210, the wireless access device AP11 acquires signal strength with each client 20, and transmits the acquired signal strength to the wireless controller AC 12.
Fig. 3 is a schematic flow chart illustrating the sub-steps included in step S210 shown in fig. 2. In this embodiment, the step S210 may include a sub-step S211 and a sub-step S212, wherein the sub-step S211 and the sub-step S212 are as follows:
in the substep S211, the AP11 sends a beacon-report message acquisition request to the client 20 communicatively connected to the AP11 according to a preset time interval.
In this embodiment, the beacon-report message acquisition request is used to acquire the beacon-report message corresponding to the client 20, the beacon-report message includes the signal strength between the client 20 and each AP11 within the signal scanning range thereof, where the beacon-report message may be a message meeting the 802.11K communication standard, and then the client 20 may be a smartphone or other mobile terminal supporting the 802.11K communication standard correspondingly. After receiving the beacon-report message acquisition request from the AP11, the client 20 responds to the beacon-report message acquisition request, and sends the beacon-report message of the client 20 to the AP 11. The preset time interval may be 30s, 50s, or 70s, and the specific time interval value may be set differently according to actual requirements.
In the substep S212, the AP11 receives the beacon-report packet corresponding to the beacon-report packet acquisition request sent by the client 20, analyzes the beacon-report packet to obtain the signal strength between the client 20 and each AP11, and sends the obtained signal strength between the client 20 and each AP11 to the AC 12.
In this embodiment, the AP11 obtains the signal strength between the corresponding client 20 and each AP11 within its signal scanning range by analyzing the received beacon-report message, and sends the signal strength between the client 20 and each AP11 within its signal scanning range to the AC12 through the network, so that the AC12 determines whether there is a suspected coverage hole at the position corresponding to the client 20 according to the signal strength between each client 20 and each corresponding AP 11.
Fig. 4 is a schematic flow chart illustrating the sub-steps included in step S210 shown in fig. 2. In this embodiment, the step S210 may further include a sub-step S213 and a sub-step S214, wherein the sub-step S213 and the sub-step S214 are as follows:
in the substep S213, the AP11 collects and receives the probe request messages broadcast by the clients 20, and obtains the signal strength between the AP11 and each client 20 based on the probe request messages.
In this embodiment, when the client 20 is not in communication connection with each AP11, the client 20 sends a probe request message to each AP11 in a broadcast manner, so as to access a wireless network corresponding to each AP 11. The AP11 correspondingly collects probe request messages broadcast by each client 20, and obtains the signal strength between the AP11 and the corresponding client 20 based on the RSSI in the received probe request messages.
In sub-step S214, the AP11 sends the obtained signal strength between the AP11 and each client 20 to the AC12 according to a preset time interval.
In this embodiment, after acquiring the signal strengths between the AP11 and the clients 20 in the signal coverage area thereof, the AP11 stores the acquired signal strengths, and correspondingly transmits the signal strengths between the AP11 and the clients 20 in the signal coverage area thereof to the AC12 at preset time intervals. The preset time interval may be 20s, 40s, or 80s, and the specific time interval value may be set differently according to actual requirements.
Referring to fig. 2 again, in step S220, the AC12 compares the signal strength between the same client 20 and each AP11 within the signal coverage with a preset signal strength threshold, determines that a suspected coverage hole exists in a location corresponding to the client 20 when the signal strength between the client 20 and each AP11 is smaller than the preset signal strength threshold, and sends the signal strength between the client 20 and each AP11 in the corresponding location where the suspected coverage hole exists to the location server 13.
In this embodiment, when the client 20 wants to access the wireless network corresponding to the AP11, the client 20 needs to be located within the signal coverage of the AP11, so that the client 20 can perform communication connection with the corresponding AP 11.
Optionally, please refer to fig. 5, which is a flowchart illustrating the sub-steps included in step S220 shown in fig. 2. In this embodiment, the step of comparing, by the AC12, the signal strength between the same client 20 and each AP11 in the signal coverage range with the preset signal strength threshold in the step S220 may include a sub-step S221 and a sub-step S222, where the sub-steps S221 and S222 are as follows:

In this embodiment, the AC12 may obtain the signal strength between the APs 11 of each client 20 within the signal coverage of the coverage hole detection system 10 by sorting the signal strength between the AP11 and the clients 20.
In sub-step S222, the AC12 compares the signal strength between each client 20 and each AP11 with a preset signal strength threshold respectively.
In this embodiment, the AC12 may determine whether there is a suspected coverage hole at the location of the corresponding client 20 by comparing the signal strength between the corresponding client 20 and each AP11 with a preset signal strength threshold.
In this embodiment, if the signal strength between the same client 20 and each AP11 in the signal coverage range of the coverage hole detection system 10 is smaller than the preset signal strength threshold, the AC12 may determine that a suspected coverage hole exists at the location where the corresponding client 20 is located, and at this time, the AC12 sends the signal strength between the client 20 corresponding to the suspected coverage hole at the location and each AP11 to the location server 13, so that the location server 13 further determines and detects the corresponding suspected coverage hole to determine whether the suspected coverage hole is a real coverage hole.

In this embodiment, the client 20 located by the location server 13 is the client 20 that has the suspected coverage hole at the corresponding location determined by the AC 12. The positioning server 13 may position the location of the client 20 according to the location of each AP11 in the signal coverage of the coverage hole detection system 10 and the signal strength between the client 20 and each AP11, of which the corresponding location is determined to have suspected coverage holes.

The location of the client 20 in the map is the location of the suspected coverage hole in the map.
In this embodiment, after the positioning server 13 positions the clients 20 having the suspected coverage holes in the corresponding positions, the number of the clients 20 in the positions corresponding to the suspected coverage holes is detected, and whether the suspected coverage holes in the corresponding positions are real coverage holes is determined according to the detection result.
