Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The application scenario described in the embodiment of the present invention is for more clearly illustrating the technical solution of the embodiment of the present invention, and does not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by a person skilled in the art that with the occurrence of a new application scenario, the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems. In the description of the present invention, the term "plurality" means two or more unless otherwise specified.
The invention provides a method for switching hot spots, which is applied to a terminal and comprises the following steps:
and step 102, determining whether to perform hotspot switching according to the first signal strength value of the first hotspot and the second signal strength value of the second hotspot.
The hotspot may be, but is not limited to, a WiFi hotspot.
The second hot spot is a hot spot of the same channel/adjacent channel as the scanned first hot spot, the same channel refers to a channel with the same hot spot signal frequency, and the adjacent channel refers to an adjacent channel determined when the hot spot signal meets the interference condition based on the communication protocol standard.
The method is applied to the Wi-Fi roaming technology, and not only can the hotspot signal intensity value of the same name of the hotspot currently connected with the terminal be considered when the hotspot is switched, but also the hotspot signal intensity values of different names can be referred, so that the situation that the hotspot is switched to the same name hotspot greatly interfered by different hotspots can be avoided.
As an optional implementation manner, the magnitudes of the first signal strength value of the first hotspot and the second signal strength value of the second hotspot are directly compared, and according to a comparison result, there are two manners of performing hotspot switching:
the first method is as follows: when the second signal intensity value is higher than the first signal intensity value, hot spot switching is not carried out;
specifically, when the second signal strength value is higher than the first signal strength value, the currently connected hotspot is kept from being switched even if the hotspot switching condition is met, for example, the signal strength value of the currently connected hotspot is lower than a hotspot switching threshold value.
The second method comprises the following steps: when the second signal strength value is lower than the first signal strength value:
comparing the first signal strength value with a preset hotspot switching threshold value, if the first signal strength value is higher than the preset hotspot switching threshold value, carrying out hotspot switching, otherwise, not carrying out hotspot switching;
in summary, when the terminal performs hotspot switching, the signal intensity value of the currently connected hotspot/scanned first hotspot is compared with the preset hotspot switching threshold, in the embodiment of the present invention, the hotspot that is compared with the preset hotspot switching threshold is not limited too much, and may be the currently connected hotspot, the scanned same-name hotspot, or the scanned different-name hotspot, and the process of comparing the hotspot with the preset threshold during switching is performed at a certain time interval, or may be a real-time process, and the time interval of the comparison process is not limited too much in the embodiment of the present invention; in addition, the process of scanning the hotspot by the terminal may be scanning at a certain time interval, which may be regarded as a real-time process, and the time interval of the scanning is not limited too much in the embodiment of the present invention. Finally, the process of scanning by the terminal and the process of switching the hot spot by the terminal may be two independent processes or two processes performed alternately, and the process is not limited too much in the embodiment of the present invention.
As another optional implementation manner, when scanning a first hotspot with the same name as a currently connected hotspot and a second hotspot with a different name from the first hotspot, the terminal adjusts a preset hotspot switching threshold according to a first signal strength value of the first hotspot and a second signal strength value of the second hotspot.
In this embodiment, the hotspot switching threshold is dynamically adjusted, and the terminal uses the first signal strength value of the first hotspot and the second signal strength value of the second hotspot as factors for adjusting the switching threshold, so that the hotspot switching threshold can be dynamically adjusted, and interference caused by different hotspots after the terminal switches hotspots due to non-adjustment of the preset hotspot switching threshold is avoided. The following description will be made with reference to specific scenarios.
As shown in fig. 2, the existing Wi-Fi roaming technology is applied to large-scale office or business places such as large enterprises, office buildings, shopping malls, and the like, a plurality of Wi-Fi hotspots "TEST" with the same name are arranged in any one of the places, when the mobile terminal 200 is connected to a first hotspot a at a first location 201 and moves within the coverage area of the plurality of Wi-Fi hotspots, and when the mobile terminal 200 moves to a second location 202, according to a set Wi-Fi hotspot switching threshold, the Wi-Fi hotspot can be automatically switched to a first hotspot b without a user separately and manually connecting other hotspots, but a second hotspot c with the same channel/an adjacent channel as/to the currently connected first hotspot a is also arranged at the second location 202, at this time, the mobile terminal 200 is interfered by the second hotspot c after being connected to the first hotspot b, so as to affect the signal transmission quality of the connected first hotspot a, the experience of the user during Wi-Fi roaming is reduced.
It can be seen that, for the case that the preset hotspot switching threshold value is used to trigger the Wi-Fi hotspot switching, interference influence may be caused on the Wi-Fi hotspot connected to the current terminal by other Wi-Fi hotspots with different names, which are located in the same channel or adjacent channels, connected to the current terminal after switching, and when the number of the Wi-Fi hotspots with different names, which are located in the same channel or adjacent channels and are located near the same position, of the Wi-Fi hotspot connected to the terminal is larger, the signal intensity is stronger, and the larger the interference on the Wi-Fi hotspot connected to the terminal is, the worse the experience of the terminal in connecting to the Wi-Fi hotspot for surfing is.
In order to avoid switching to a hotspot with the same name, which is greatly affected by different hotspots, in this embodiment, a preset hotspot switching threshold value is adjusted according to a difference between a first signal strength value of the first hotspot and a second signal strength value of the second hotspot.
Fig. 3 is a flowchart illustrating the adjustment of the preset hot spot switching threshold in this embodiment, which specifically includes the following steps:
Step 302: determining whether the difference between the second signal strength value and the first signal strength value is greater than a preset low threshold, if so, performing step 303, otherwise, performing step 304.
In implementation, for the case that there are a plurality of first hot spots/second hot spots scanned, the following two ways are used to determine whether the difference is greater than the preset low threshold:
the first method is as follows: determining a first signal strength value with the maximum signal strength value of a plurality of scanned first hot spots, determining a second signal strength value with the maximum signal strength value of a plurality of scanned second hot spots, and determining whether the difference value between the second signal strength value and the first signal strength value is greater than a preset low threshold value;
in a second mode, an average value of signal intensity values (higher than a certain value) of a plurality of scanned first hotspots is determined as the first signal intensity value, a second average value of signal intensity values (higher than a certain value) of a plurality of scanned second hotspots is determined as the second signal intensity value, and whether a difference value between the second signal intensity value and the first signal intensity value is greater than a preset low threshold value is determined.
In this embodiment, how to determine the first signal strength value and the second signal strength value is not specifically limited, and may be determined according to actual requirements or user requirements.
Step 303: and reducing a preset hot spot switching threshold value.
The preset hot spot switching threshold value may be defined by the user, or may be factory default.
Specifically, when it is determined that the difference between the second signal strength value and the first signal strength value is greater than the preset low threshold, the preset hot spot switching threshold is reduced by the amplitude value corresponding to the range according to the range in which the difference is located.
According to the range of the difference value, the following two implementation modes are adopted, and the preset hot spot switching threshold value is reduced by the amplitude value corresponding to the range:
1) when the difference value is determined to be larger than a preset high threshold value, reducing a preset hot spot switching threshold value by the preset high threshold value;
the difference is greater than the preset high threshold, which indicates that the second signal strength value is much greater than the first signal strength value, and the second hot spot may generate a large interference to the first hot spot.
2) And when the difference value is determined to be not smaller than a preset low threshold value and not larger than a preset high threshold value, reducing a preset hotspot switching threshold value by the absolute value of the preset low threshold value.
The difference is not smaller than the preset low threshold and not larger than the preset high threshold, which indicates that the second signal strength value is slightly larger than or equal to the first signal strength value, or the second hot spot signal strength is slightly smaller than the first hot spot signal strength, and according to the interference definition, even if the first signal strength value is higher than the second signal strength value within a certain range, the second hot spot can still generate small interference to the first hot spot.
According to interference definition in a communication standard, determining a signal intensity range in which the same channel/adjacent channel can generate interference, and determining a preset low threshold value and a preset high threshold value according to the intensity range. Optionally, the preset low threshold is a negative number, and the preset high threshold is a positive number.
Step 304: and restoring the current hotspot switching threshold value to a preset hotspot switching threshold value.
In summary, according to the two different interference situations, the preset hot spot handover threshold may be adjusted to different degrees, specifically, when it is determined that the difference between the second signal strength value and the first signal strength value is greater than the preset low threshold, according to a range in which the difference is located, the preset hot spot handover threshold is decreased by an amplitude value corresponding to the range, when the second hot spot signal strength is greater than the first hot spot signal strength, the hot spot handover threshold is decreased to a greater degree, when the second hot spot signal strength is slightly greater than or slightly less than the first hot spot signal strength, the hot spot handover threshold is decreased to a lesser degree, and when the second hot spot signal strength is far less than the first hot spot signal strength, the current hot spot handover threshold is restored to the preset hot spot handover threshold. According to the embodiment of the application, the preset hotspot switching threshold value can be adjusted more accurately according to the interference of different hotspots to the same hotspot in different degrees in actual conditions, so that the signal strength of the switching hotspot is ensured, the influence of the interference is considered, and the Wi-Fi roaming experience of a user can be greatly improved.
In order to optimize the hot spot switching threshold value to the greatest extent, the hot spot switching threshold value is dynamically adjusted in consideration of two factors, namely, a hot spot with a different name from a currently connected hot spot, and a difference value between signal strengths of the hot spot with the same name and the hot spot with the different name, a preset hot spot switching threshold value is adjusted, so that the hot spot switching threshold value is an optimal hot spot switching threshold value, a specific implementation procedure of adjusting the hot spot switching threshold value is described with a certain large place shown in fig. 2 as a background, a first position 201 and a second position 202 are respectively provided with a hot spot a with the same name and a first hot spot b, wherein the first hot spot a and the first hot spot b are named as TEST, the distance between the first hot spot a and the first hot spot b is 15 meters, the first hot spot a works at 2412MHz, the first hot spot b works at 2437MHz, and meanwhile, a second hot spot c which works at the same channel as the first hot spot b, and works at 2437MHz is arranged around the first hot spot b at the second position 202, the second hotspot name is GANRAO.
As shown in fig. 4, the specific implementation steps for adjusting the preset hot spot switching threshold value are as follows:
step 401: the terminal 200 connects to the first hot spot a, the scanned first hot spot a and the first hot spot b at the first location 201, and determines a signal strength value.
Specifically, the terminal 200 determines, at the first location 201, that the signal strength RSSI _ a of the first hot spot a is-50 db, and that the signal strength RSSI _ B of the first hot spot B is-73 db.
Step 402: the terminal 200 determines that hotspot switching is not required according to the signal strength values of the first hotspot a and the first hotspot b and a hotspot switching threshold value;
and if the signal strength value of the first hotspot a is higher than the hotspot switching threshold value, determining that hotspot switching is not needed.
Step 403: the terminal 200 moves from the first position 201 to the second position 202, scans the first hot spot a, the first hot spot b and the second hot spot c and determines a signal strength value;
specifically, the signal strength value of the first hotspot B is identified as RSSI _ B, and the signal strength value of the second hotspot c is identified as RSSI _ G.
Step 404: a difference in signal strength values for the first hotspot b and the second hotspot c is determined.
Step 405: and determining whether the difference value is smaller than a preset low threshold value, if so, executing step 406, otherwise, executing step 407.
Step 406: and restoring the current hotspot switching threshold value to a preset hotspot switching threshold value.
Specifically, the preset low threshold is-5 db, and the preset hot spot switching threshold is-70 db;
when RSSI _ G-RSSI _ B < -5db, the current hotspot switching threshold value is restored to-70 db.
Step 407: determining whether the difference is greater than a preset high threshold, if so, performing step 408; otherwise, step 409 is performed.
Step 408: and reducing the preset hot spot switching threshold value by 10 db.
Specifically, the preset high threshold is 10db, and when RSSI _ G-RSSI _ B > 10db, the preset hot spot handover threshold is reduced to-80 db.
Step 409: and when the difference is determined to be not smaller than the preset low threshold and not larger than the preset high threshold, reducing the preset hotspot switching threshold by 5 db.
Specifically, when-5 db is less than or equal to RSSI _ G and RSSI _ B is less than or equal to 10db, the preset hotspot switching threshold value is reduced to-75 db.
The above-mentioned determination process of the range of the difference value may be performed successively or in parallel.
As an optional implementation manner, while adjusting the hotspot switching threshold value described in the foregoing embodiment, the terminal scans a currently connected hotspot and determines a signal strength value of the connected hotspot, and directly performs hotspot switching when the signal strength value of the currently connected hotspot is smaller than the hotspot switching threshold value, and may determine to which hotspot to switch according to the existing manner, which is not described in detail herein.
