Example 1
As shown in the flowchart of fig. 1, the present embodiment includes the following steps:
step S101: obtaining an RSSI (Received Signal Strength indication) value of a wireless Signal of an AP (access point), where the wireless Signal includes a first wireless Signal and a second wireless Signal, and the RSSI value includes a first RSSI value of the first wireless Signal and a second RSSI value of the second wireless Signal;
in this embodiment, the first wireless signal may be a 2.4 gwifii (wireless fidelity wireless network) signal, the second wireless signal may be a 5GWIFI signal, an application scenario may be determined in a house, the house has one or more wireless routers, in this embodiment, for convenience of explanation, one router is provided, the router may simultaneously release a WIFI signal of the 2.4GWIFI signal/the 5GWIFI signal, the WIFI signal may be detected by a mobile terminal of a user, the mobile terminal of the user may be a smart phone, a laptop, or a tablet or the like mobile terminal capable of being connected to WIFI, in this embodiment, when detecting the WIFI of the router, the router sends a beacon packet to the mobile terminal on the hand of the user, the beacon packet includes SSID (Service Identifier, Service Set Identifier) of WIFI, RSSI, channel, and power data information, so that the mobile terminal of the user may receive RSSI data and connection rate of two channels of WIFI, meanwhile, in order to facilitate switching, the SSIDs of the 2.4GWIFI signal and the 5GWIFI signal of the wireless router both correspond to the same SSID.
Step S102, judging whether the second RSSI value is larger than the first RSSI value;
the RSSI value is the received power of the mobile terminal receiving WIFI, the larger the received power is, the better the signal is, the smaller the received power is, the worse the signal is, for the 2.4GWIFI signal and the 5GWIFI signal, both the number of antennas and the channel bandwidth of the 5GWIFI signal are better than those of the 2.4GWIFI signal, therefore when the RSSI value of the 5GWIFI signal is greater than that of the 2.4GWIFI signal, the network quality after the 5GWIFI signal is necessarily connected is better than that of the 2.4GWIFI signal, therefore, when the second RSSI value is greater than the first RSSI value, step S103 is executed, otherwise step S104 is executed.
Step S103: the second wireless signal is connected.
Step S104: judging whether a second connection rate of the second wireless signal is greater than a first connection rate of the first wireless signal;
in this embodiment, when the RSSI value of the 5 gwifii signal is less than the RSSI value of the 2.4 gwifii signal, the connection rate of the 5 gwifii signal is still greater than the connection rate of the 2.4 gwifii signal, so that when the two signals are not too different, the connection rates of the two signals are further compared, and the second connection rate is greater than the first connection rate, step S103 is executed to connect the second wireless signal, and if the second connection rate is less than the first connection rate, the connection quality of the 2.4 gwifii signal is better than the connection quality of the 5 gwifii signal, so that step S105 is executed to connect the first wireless signal.
Step S105: the first wireless signal is connected.
If the RSSI value of the 5 gwifii signal is much smaller than that of the 2.4 gwifii signal, the comparison of the connection rates is not performed, the threshold range of the judgment fluctuates between 2dB and 10dB according to the actual situation, for example, different APs, the number of antenna installations for the 2.4 gwifii signal and the 5 gwifii signal is different, and the channel frequency requirements of the 2.4 gwifii signal and the 5 gwifii signal allowed by the APs are also different in different countries, so that the WIFI signal quality has differences and needs to be set differently.
This embodiment is through preferentially judging RSSI value then judging which WIFI that should connect according to the connection rate, has guaranteed the stability of connecting the signal, has solved the problem that weak network connection experience that kicks the cause is not good to a certain extent simultaneously, has considered the difference of 5 GWIFISI signals and 2.4 GWIFII signals in the method that the WIFI switches for whole switching flow is more retrencied, makes the user be difficult to experience the switching of WIFI.
Example 2
Referring to a flow chart shown in fig. 2, embodiment 2 of the present invention further discloses the following technical features on the basis of embodiment 1, and the specific technical features include the following steps:
step S201: confirming the change amplitude of the RSSI value of the currently connected WIFI signal;
the user can not keep still at home all the time, and when the handheld mobile terminal of user removed, WIFI signal strength etc. of current connection all can produce the change, then is fit for connecting the stronger 2.4 GWIFII signal of penetrability when keeping away from the signal source, then is fit for connecting 5 GWIFII signals when being close to the signal source, so need detect the RSSI value variation amplitude of current WIFI signal.
Step S202: judging whether the variation amplitude of the RSSI value exceeds a preset threshold value or not;
when the RSSI value of the currently connected WIFI signal changes and exceeds a certain threshold, it is determined that the network environment has changed, and therefore it is necessary to determine again whether the currently connected WIFI is the optimal choice.
Step S203: and if the variation amplitude of the RSSI value exceeds the threshold value, detecting and switching the WIFI signal, and if not, keeping the current WIFI connection.
In this embodiment, the WIFI of the 5GWIFI signal connected to the user in the living room moves to the room of the user, and the penetration of the 5GWIFI signal is not good, so that the attenuation is faster than that of the 2.4GWIFI signal, and at this time, the RSSI value attenuation of the WIFI signal exceeds the threshold, the steps S101 to S105 are executed again, where, because the specified channels of the wireless signal in different countries are different, and the properties embodied in different hardware are different, it is determined whether the threshold that needs to be determined for reconnection will float according to the environment, and according to experience and experimental data, the value range of the threshold is generally 2dB to 10 dB.
Example 3
Referring to fig. 3, a flowchart of a switching method for multiple different WIFI signals when multiple wireless routers and wireless APs exist in an application environment is shown.
Step S301: and screening out the wireless signal with the highest second RSSI value from the received wireless signal data.
When WIFI signals sent by a plurality of routers exist in a home network environment, the strength of the 5 GWIFII signal is preferentially detected, a 5 GWIFII signal with the highest connection strength is searched from all detected signals, then the 5 GWIFII signal is compared with a homologous 2.4 GWIFII signal, and which WIFI signal is to be connected is judged.
For example, a home has a wireless router in a routing mode and a wireless AP in a bridge mode, the router is disposed in a study room, the wireless AP is in a living room, and amplifies a WIFI signal received from the wireless router, so that the WIFI signal can cover the whole house, at this time, when a user is in the study room, the user is close to the router, so the RSSI value of the 5GWIFI signal of the router is greater than the RSSI value of the 2.4GWIFI signal, and the wireless AP is far away from the user, so the 5GWIFI signal of the router is connected, when the user leaves the study room to go through the living room to a bedroom, the WIFI signal from the router is attenuated by two walls, the signal strength of the router is weaker than that of the wireless AP, and because the 5GWIFI signal is not highly permeable, and the connection rate is not as high as that of the wireless signal of the 2.4GWIFI signal, so that the user is connected with the 2.4GWIFI signal sent by the wireless AP.
Step S302: and judging whether the second RSSI value of the wireless signal is larger than the first RSSI value.
This step is identical to the step S102, and is not described herein again.
Step S303: the second wireless signal is connected.
This step is identical to the step S103, and is not described herein again.
Step S304: judging whether the second connection rate is greater than the first connection rate;
this step is identical to the step S104, and is not described herein again.
Step S305: the first wireless signal is connected.
This step is identical to the step S105, and is not described herein again.
