[0045] Next, the embodiments of the present application are described in detail.

[0046] The embodiment of the present application provides a method for setting a roaming threshold value, which is applied to a network device that has a roaming threshold setting function enabled, such as Figure 1 As shown, the method may include the following steps:

[0047] S11 . After determining that the target AP is online, obtain the signal strength of the target AP detected by the neighboring AP of the target AP and reported by the neighboring AP of the target AP.

[0048] S12. Determine whether a target AP exists among multiple APs deployed in pre-deployed multiple location scenarios; if the determination result is yes, execute step S13; if the determination result is no, execute step S14.

[0049] S13. Determine the roaming threshold that the target AP needs to use based on the target AP's transmission power, the obtained maximum signal strength of the target AP, the preset signal strength, and the roaming threshold baseline table corresponding to the target AP's location scenario obtained locally, and send the determined roaming threshold to the target AP.

[0050] S14: Determine the roaming threshold to be used by the target AP based on the transmit power, maximum signal strength, preset signal strength, and a locally acquired roaming threshold baseline table corresponding to common scenarios, and send the determined roaming threshold to the target AP.

[0051] It should be noted that, in the embodiment of the present application, the roaming threshold baseline table corresponding to each location scenario and common scenario includes the various transmit powers supported by the target AP and their corresponding roaming thresholds.

[0052] Furthermore, when the network device enabled with the roaming threshold setting function is an AC, the target AP is a Fit AP.

[0053] Alternatively, when the network device enabled with the roaming threshold setting function is a cloud platform, the target AP is a fat AP.

[0054] If the roaming threshold setting function is enabled on an AC, you can obtain the target AP's signal strength as reported by its neighboring APs using the following methods:

[0055] Receive the target AP's signal strength reported by other APs that have detected the target AP.

[0056] In a case where the network device enabled with the roaming threshold setting function is a cloud platform, upon receiving an online message reported by an AC to which the target AP is connected and indicating that the target AP is online, it is determined that the target AP is online.

[0057] In this case, the network device enabled with the roaming threshold setting function can obtain the signal strength of the target AP detected by the neighboring AP of the target AP as reported by the neighboring AP in the following way:

[0058] Receives the signal strength of the target AP reported by the AC and reported by other APs that have detected the target AP.

[0059] Here, no matter which acquisition method is used, other APs can be understood as neighboring APs of the target AP, and the signal strength of the target AP reported by other APs is the signal strength measured by other APs when receiving the detection message broadcast by the target AP.

[0060] It should be further noted that, in the embodiment of the present application, the roaming threshold baseline table corresponding to each location scenario is generated in the following manner:

[0061] For each location scenario, under a sampling environment corresponding to the location scenario, for each transmit power supported by the first sampling AP, obtaining a signal strength of a sampling wireless terminal located at a midline position between the first sampling AP and the second sampling AP detected by the first sampling AP when operating based on the transmit power, and determining the obtained signal strength as a roaming threshold corresponding to the transmit power, wherein all transmit powers supported by the first sampling AP are the same as all transmit powers supported by the target AP, and the signal strength of the first sampling AP detected by the second sampling AP is a preset signal strength;

[0062] A baseline table including each transmit power and its corresponding roaming threshold is generated and used as the roaming threshold baseline table corresponding to the location scenario.

[0063] In addition, the roaming threshold baseline table corresponding to common scenarios is generated in the following way:

[0064] Calculate the average value of the roaming thresholds corresponding to the same transmit power in the roaming threshold baseline table generated by the system for all location scenarios, and use the calculated average value as the new roaming threshold corresponding to the same transmit power. All roaming threshold baseline tables contain the same transmit power.

[0065] A baseline table including all transmit powers and their corresponding new roaming thresholds is generated and used as a roaming threshold baseline table corresponding to common scenarios.

[0066] Here, the preset signal strength may be a better signal strength within the wireless coverage range of a single AP, for example, the preset signal strength may be -65dBm.

[0067] It should be noted that, for the same transmit power, in different location scenarios, the signal strength of the relevant sampled wireless terminal obtained by the network device with the roaming threshold setting function enabled may be different.

[0068] These location scenarios may include a designated stadium, a designated office area, a designated factory workshop, and so on.

[0069] For example, when the location scenario is a target stadium, assuming that the network device that enables the roaming threshold setting function is an AC, assuming that the transmission power supported by the first sampling AP has a power range of 1 to 30 dBm, and assuming that the preset signal strength is -65 dBm, then the roaming threshold baseline table corresponding to the target stadium generated by the AC can be shown in Table 1 below.

[0070]

[0071] Table 1

[0072] Specifically, in the above step S12, the network device with the roaming threshold setting function enabled may determine the roaming threshold to be used by the target AP in the following manner:

[0073] If the maximum signal strength is greater than the preset signal strength, the difference between the maximum signal strength and the preset signal strength is calculated, and the calculated difference is subtracted from the transmit power to obtain a first calculation result. The roaming threshold corresponding to the first calculation result is searched in the roaming threshold baseline table corresponding to the location scenario of the target AP, and the found roaming threshold is determined as the roaming threshold to be used by the target AP.

[0074] If the maximum signal strength is less than the preset signal strength, the difference between the preset signal strength and the maximum signal strength is calculated, and the transmit power and the calculated difference are added to obtain a second calculation result. The roaming threshold corresponding to the second calculation result is searched in the roaming threshold baseline table corresponding to the location scenario of the target AP, and the found roaming threshold is determined as the roaming threshold to be used by the target AP.

[0075] For example, assume that the network device enabled with the roaming threshold setting function is an AC, assume that the location scenario of the target AP is the above-mentioned target stadium, assume that the transmit power of the target AP is 20dBm, and if the maximum signal strength obtained by the AC is -65dBm, then the AC directly determines the roaming threshold corresponding to 20dBm in Table 1 as the roaming threshold that the target AP needs to use.

[0076] If the maximum signal strength obtained by the AC is -60dBm, that is, greater than the preset signal strength, in this case, the AC first calculates the difference between the maximum signal strength obtained and the preset signal strength. Then, it subtracts the calculated difference from the transmit power to obtain the result (that is, 15dBm). The AC searches the roaming threshold corresponding to 15dBm in the roaming threshold baseline table corresponding to the target stadium and determines the roaming threshold corresponding to 15dBm as the roaming threshold to be used by the target AP.

[0077] Specifically, in the above step S13, the network device with the roaming threshold setting function enabled may determine the roaming threshold to be used by the target AP in the following manner:

[0078] If the maximum signal strength is the preset signal strength, the roaming threshold corresponding to the transmit power is searched in the roaming threshold baseline table for common scenarios. The found roaming threshold is used as the roaming threshold for the target AP.

[0079] If the maximum signal strength is greater than the preset signal strength, the difference between the maximum signal strength and the preset signal strength is calculated, and the calculated difference is subtracted from the transmit power to obtain a third calculation result. The roaming threshold corresponding to the third calculation result is searched in the roaming threshold baseline table corresponding to the common scenario, and the found roaming threshold is determined as the roaming threshold to be used by the target AP.

[0080] If the maximum signal strength is less than the preset signal strength, the difference between the preset signal strength and the maximum signal strength is calculated, and the transmit power and the calculated difference are added to obtain a fourth operation result. In the roaming threshold baseline table corresponding to the normal scenario, the roaming threshold corresponding to the fourth operation result is searched, and the found roaming threshold is determined as the roaming threshold to be used by the target AP.

[0081] The embodiment of the present application also provides a roaming threshold setting method, which is applied to a cloud AP, such as Figure 2 As shown, the method may include the following steps:

[0082] S21. After powering on, obtain the signal strength of the neighboring AP detected by the neighboring AP reported by the neighboring AP.

[0083] S22. If the location scenario in which the device is located is configured locally, the device sets the roaming threshold to be used based on its own transmit power, the maximum signal strength obtained, the preset signal strength, and the roaming threshold baseline table corresponding to the location scenario in which the device is located obtained locally.

[0084] S23. If the location scenario is not configured locally, set the roaming threshold to be used based on the transmit power, maximum signal strength, preset signal strength, and the roaming threshold baseline table corresponding to the common scenario obtained locally.

[0085] It should be noted that, in the embodiment of the present application, the roaming threshold baseline table corresponding to the location scenario and the common scenario includes the various transmit powers supported by the scenario and the corresponding roaming thresholds.

[0086] It should be further noted that the roaming threshold baseline table corresponding to the location scenario of the cloud AP and the common scenario can be generated by the above-mentioned network device with the roaming threshold setting function enabled, and configured by the administrator on the cloud AP side.

[0087] Specifically, in the above step S22, the cloud AP can set the roaming threshold to be used by itself in the following manner:

[0088] If the maximum signal strength is the preset signal strength, the roaming threshold corresponding to the transmit power is searched in the roaming threshold baseline table corresponding to the location scenario, and the roaming threshold found is set as the roaming threshold to be used.

[0089] If the maximum signal strength is greater than the preset signal strength, the device calculates the difference between the maximum signal strength and the preset signal strength, performs a subtraction operation on the transmit power and the calculated difference to obtain a first calculation result, searches the roaming threshold corresponding to the first calculation result in the roaming threshold baseline table corresponding to the location scenario, and sets the found roaming threshold as the roaming threshold to be used by the device.

[0090] If the maximum signal strength is less than the preset signal strength, the difference between the preset signal strength and the maximum signal strength is calculated, and the transmit power and the calculated difference are added to obtain a second calculation result. The roaming threshold corresponding to the second calculation result is searched in the roaming threshold baseline table corresponding to the location scenario, and the found roaming threshold is determined as the roaming threshold to be used by the target AP.

[0091] Specifically, in the above step S23, the cloud AP can set the roaming threshold to be used by itself in the following manner:

[0092] If the maximum signal strength is the preset signal strength, the roaming threshold corresponding to the transmit power is searched in the roaming threshold baseline table corresponding to the common scenario, and the found roaming threshold is set as the roaming threshold to be used.

[0093] If the maximum signal strength is greater than the preset signal strength, the device calculates the difference between the maximum signal strength and the preset signal strength, performs a subtraction operation on the transmit power and the calculated difference to obtain a third calculation result, searches the roaming threshold corresponding to the third calculation result in the roaming threshold baseline table corresponding to the common scenario, and sets the found roaming threshold as the desired roaming threshold.

[0094] If the maximum signal strength is less than the preset signal strength, the difference between the preset signal strength and the maximum signal strength is calculated, and the transmit power and the calculated difference are added to obtain a fourth operation result. In the roaming threshold baseline table corresponding to the normal scenario, the roaming threshold corresponding to the fourth operation result is searched, and the found roaming threshold is determined as the roaming threshold to be used by the target AP.

[0095] As can be seen from the above technical solutions, in the embodiment of the present application, a network device with the roaming threshold setting function enabled can determine the roaming threshold that the target AP needs to use based on the transmit power of the online target AP, the maximum signal strength of the target AP's signal strengths detected by neighboring APs and reported by neighboring APs, and a related roaming threshold baseline table; or, a cloud AP can set the roaming threshold that the target AP needs to use based on its own transmit power, the maximum signal strength of the signal strength detected by neighboring APs and reported by neighboring APs, and a related roaming threshold baseline table. In this way, empirical values ​​are no longer used, and wireless terminals can be guided to roam in a timely manner, thereby improving the roaming experience of wireless terminals.

[0114] If the maximum signal strength is less than the preset signal strength, the difference between the preset signal strength and the maximum signal strength is calculated, and the transmission power and the calculated difference are added to obtain a second calculation result. In the roaming threshold baseline table corresponding to the location scenario of the target AP, the roaming threshold corresponding to the second calculation result is searched, and the found roaming threshold is determined as the roaming threshold that the target AP needs to use.

[0119] This application also provides a roaming threshold setting device, which is applied to a cloud AP. The schematic diagram of its structure is shown in FIG. Figure 4 As shown, specifically including:

[0120] An acquisition module 41 is configured to, after the cloud AP is powered on, acquire a signal strength of the cloud AP detected by the neighbor AP, as reported by the neighbor AP of the cloud AP;
