And step 302, the electronic equipment determines a first Wi-Fi network from the at least two Wi-Fi networks according to the at least two second signal parameters, and performs VoWiFi service through the first Wi-Fi network.
In this embodiment of the present application, the first Wi-Fi network is a Wi-Fi network corresponding to a largest second signal parameter of the at least two second signal parameters.
In this embodiment of the application, after the electronic device obtains the at least two second signal parameters of the at least two Wi-Fi networks at the current time, the electronic device may compare the at least two second signal parameters, determine the signal quality of each of the at least two Wi-Fi networks according to each second signal parameter, and rank the at least two Wi-Fi networks according to the signal quality of each Wi-Fi network, thereby determining a Wi-Fi network (i.e., a first Wi-Fi network) with the best signal quality of the at least two Wi-Fi networks.
In the embodiment of the application, the electronic device may transmit data corresponding to the VoWiFi service through the first Wi-Fi network (that is, the electronic device performs the VoWiFi service through the first Wi-Fi network).
In the embodiment of the application, when the electronic device needs to perform the VoWiFi service, the electronic device can acquire a second signal parameter of each of at least two connected Wi-Fi networks at the current moment, and determine a first Wi-Fi network corresponding to the largest second signal parameter from the at least two Wi-Fi networks by comparing the acquired at least two second signal parameters, so that the electronic device can perform the VoWiFi service through the first Wi-Fi network, and the quality of performing the VoWiFi service by the electronic device through the Wi-Fi networks can be improved.
Step 202, under the condition that the first signal parameter of the first Wi-Fi network is smaller than or equal to a first preset threshold value and the first signal parameter of the second Wi-Fi network is larger than or equal to a second preset threshold value, the electronic device controls the current Wi-Fi network of the electronic device for VoWiFi service to be switched from the first Wi-Fi network to the second Wi-Fi network.
In the embodiment of the application, the second Wi-Fi network is any Wi-Fi network except the first Wi-Fi network in the at least two Wi-Fi networks.
In the embodiment of the application, the electronic device may obtain a first preset threshold and a second preset threshold which are preset, and judge a magnitude relation between a first signal parameter of a first Wi-Fi network and the first preset threshold, and a magnitude relation between the first signal parameter of a second Wi-Fi network and the second preset threshold.
Optionally, in this embodiment of the application, the electronic device may first determine a size relationship between a first signal parameter of the first Wi-Fi network and a first preset threshold, and then determine a size relationship between a first signal parameter of the second Wi-Fi network and a second preset threshold when the first signal parameter of the first Wi-Fi network is less than or equal to the first preset threshold; or, the electronic device may simultaneously determine a magnitude relationship between a first signal parameter of the first Wi-Fi network and a first preset threshold, and a magnitude relationship between a first signal parameter of the second Wi-Fi network and a second preset threshold.
Optionally, in this embodiment of the application, the electronic device may switch the VoWiFi service from the first Wi-Fi network to the second Wi-Fi network, so that the VoWiFi service may be performed through the second Wi-Fi network.
Optionally, in this embodiment of the application, the electronic device may sequentially determine whether a first signal parameter of a Wi-Fi network other than the first Wi-Fi network in the at least two Wi-Fi networks is greater than or equal to a second preset threshold, so that when the first signal parameter of a certain Wi-Fi network is greater than or equal to the second preset threshold, the Wi-Fi network is determined as a second Wi-Fi network; or, the electronic device may simultaneously determine whether the first signal parameter of all Wi-Fi networks except the first Wi-Fi network of the at least two Wi-Fi networks is greater than or equal to a second preset threshold, so that when the first signal parameter of a certain Wi-Fi network is greater than or equal to the second preset threshold, the Wi-Fi network is determined as a second Wi-Fi network.
The embodiment of the application provides a network switching method, wherein when an electronic device performs a VoWiFi service through a first Wi-Fi network, a first signal parameter of each of a plurality of connected Wi-Fi networks can be acquired in real time, and a signal quality condition of each Wi-Fi network is determined by determining a magnitude relation of the first signal parameter of each Wi-Fi network (for example, the magnitude relation between the first signal parameter of the first Wi-Fi network and a first preset threshold, and the magnitude relation between the first signal parameter of a second Wi-Fi network and a second preset threshold), so that one Wi-Fi network with better signal quality is selected from remaining Wi-Fi networks (namely, Wi-Fi networks other than the first Wi-Fi network) under the condition that the signal quality of the first Wi-Fi network is poor (namely, the first signal parameter of the first Wi-Fi network is less than or equal to the first preset threshold) The first signal parameter is greater than or equal to a first preset threshold value, so as to continue the VoWiFi service, and therefore the problem of interruption of the VoWiFi service can be avoided, and thus the quality of the VoWiFi service performed by the electronic device through the Wi-Fi network can be improved.
Alternatively, in the embodiment of the present application, the step 202 may be replaced with the step 203 described below.
And 203, under the condition that the first signal parameter of the connected first Wi-Fi network is greater than or equal to a first preset threshold value, the electronic equipment continues to perform VoWiFi service through the first Wi-Fi network.
Optionally, in this embodiment of the application, after the electronic device obtains the first signal parameter of each of the at least two Wi-Fi networks, if the electronic device determines that the first signal parameter of the first Wi-Fi network is greater than or equal to the first preset threshold, the electronic device may continue to perform the VoWiFi service through the first Wi-Fi network without determining a magnitude relationship between the first signal parameter of the other Wi-Fi networks (i.e., the Wi-Fi networks other than the first Wi-Fi network of the at least two Wi-Fi networks) and the second preset threshold.
It can be understood that when the electronic device determines that the first signal parameter of the first Wi-Fi network is greater than or equal to the first preset threshold (i.e., the current signal quality of the first Wi-Fi network is better), the electronic device continues to perform the VoWiFi service through the first Wi-Fi network without switching the Wi-Fi network performing the VoWiFi service. Therefore, the electronic equipment does not need to judge the size relation between the first signal parameter of other Wi-Fi networks and the second preset threshold value.
In the embodiment of the application, when the electronic equipment judges that the first signal parameter of the first Wi-Fi network is greater than or equal to the first preset threshold value, the electronic equipment can continue to perform the VoWiFi service through the first Wi-Fi network without switching the Wi-Fi network for performing the VoWiFi service, so that the electronic equipment can continue to perform the VoWiFi service through the first Wi-Fi network with better signal quality, and the quality of the VoWiFi service performed by the electronic equipment through the Wi-Fi network can be improved.
Optionally, in this embodiment of the present application, as shown in fig. 3 with reference to fig. 1, before "the electronic device controls the electronic device to perform the current Wi-Fi network for the VoWiFi service and switch from the first Wi-Fi network to the second Wi-Fi network" in step 202, the network switching method provided in this embodiment of the present application further includes step 401 below, and step 202 may be specifically implemented by step 202a below.
Step 401, when the first signal parameter of the first Wi-Fi network is less than or equal to a first preset threshold and the first signal parameter of the second Wi-Fi network is greater than or equal to a second preset threshold, the electronic device obtains a target duration.
In this embodiment of the application, the target time duration is a time duration from a first time to a second time, where the first time is a time when the VoWiFi service starts to be provided through the first Wi-Fi network, and the second time is a current system time of the electronic device.
Optionally, in this embodiment of the application, when the electronic device performs the VoWiFi service through the first Wi-Fi network, the electronic device may execute a timing function to determine a duration (i.e., a target duration) of the VoWiFi service performed by the electronic device through the first Wi-Fi network.
Optionally, in this embodiment of the application, when the electronic device determines that the first signal parameter of the first Wi-Fi network is less than or equal to a first preset threshold and the first signal parameter of the second Wi-Fi network is greater than or equal to a second preset threshold, the electronic device may obtain a duration (i.e., a target duration) recorded by the timing function at the current time.
Step 202a, under the condition that the target duration is greater than or equal to the preset duration, the electronic equipment controls the electronic equipment to carry out the current Wi-Fi network of the VoWiFi service, and the first Wi-Fi network is switched to the second Wi-Fi network.
Optionally, in this embodiment of the application, the electronic device may first obtain a preset duration, and then determine a size relationship between the target duration and the preset duration, so that when the target duration is greater than or equal to the preset duration, the electronic device may switch the VoWiFi service from the first Wi-Fi network to the second Wi-Fi network, and thus may perform the VoWiFi service through the second Wi-Fi network.
In the embodiment of the application, when the electronic device determines that the first signal parameter of the first Wi-Fi network is less than or equal to a first preset threshold and the first signal parameter of the second Wi-Fi network is greater than or equal to a second preset threshold, the electronic device may further obtain a target duration for performing the VoWiFi service through the first Wi-Fi network, and determine a size relationship between the target duration and the preset duration, so that when the target duration is greater than or equal to the preset duration, the electronic device may switch the VoWiFi service from the first Wi-Fi network to the second Wi-Fi network, so as to perform the VoWiFi service through the second Wi-Fi network, and therefore the electronic device may control the electronic device to switch the frequency of the Wi-Fi network for performing the VoWiFi service through the preset duration.
Optionally, in this embodiment, with reference to fig. 1, as shown in fig. 4, before the step 201, the network handover method provided in this embodiment further includes the following step 501 and step 502.
Step 501, the electronic device receives a first input of a user.
In an embodiment of the present application, the first input is an input of a target threshold value by a user, where the target threshold value includes at least one of: the system comprises a first preset threshold, a second preset threshold and a preset time length, wherein the preset time length is the minimum time length for allowing switching from one Wi-Fi network to another Wi-Fi network.
Optionally, in this embodiment of the present application, the user may perform a first input in the setting application, so that the electronic device may determine a target threshold value for switching a Wi-Fi network for the VoWiFi service.
Optionally, in this embodiment of the application, the first preset threshold is used to determine whether the current signal quality of the Wi-Fi network is in a poor range, the second preset threshold is used to determine whether the current signal quality of the Wi-Fi network is in a good range, and the preset time duration is used to control the electronic device to switch the frequency of the Wi-Fi network performing the VoWiFi service (that is, the electronic device is only allowed to complete once switching of the Wi-Fi network performing the VoWiFi service within the preset time duration).
Step 502, the electronic device responds to the first input and stores the target threshold value.
Optionally, in this embodiment of the application, the electronic device may record a target threshold corresponding to the first input of the user, and store the target threshold, so as to determine whether to switch a Wi-Fi network for performing a VoWiFi service according to the target threshold when the electronic device performs the VoWiFi service through the Wi-Fi network, and control the electronic device to switch a frequency of the Wi-Fi network for performing the VoWiFi service.
In the embodiment of the application, the electronic device may determine the target threshold value according to the first input of the user, and store the target threshold value, so as to control the electronic device to switch the specific situation of the Wi-Fi network for performing the VoWiFi service through the target threshold value, thereby improving the quality of the VoWiFi service performed by the electronic device through the Wi-Fi network.
It should be noted that, in the network handover method provided in the embodiment of the present application, the execution main body may be a network handover device, or a control module in the network handover device for executing the network handover method.
