With the development of intelligent science and technology and industry, users have higher requirements on viewing experience in the use process of electronic equipment (such as a television). Currently, when a television is connected to a single-frequency router, since the wireless network (WiFi) speed is mainly determined by the network speed upstream of the router and the hardware capability of the WiFi chip, the network experience is not greatly different among the televisions. However, when the dual-band router is connected, because the houses of some families are relatively large and the rooms are relatively many, the television and the router may not be in the same room, and the android system installed on the television can preferentially select a wireless network with a 5GHz frequency band, and the 5G wireless network behind the partition wall is unstable, so that a user can have some network experience problems such as blocking when watching online videos by using the wireless network.

The specific process of selecting and connecting the wireless network by the television in the related scheme is described by way of example with reference to the flow chart of connecting the wireless network by the television provided in the related scheme shown in fig. 1.

Firstly, a user selects a wireless network to be connected on a menu interface on a television, and inputs a corresponding password, at this time, the television transmits a wireless network name (SSID), the password and an encryption mode (WPA 2 or WPA 3) selected by the user to an application framework (framework) layer of an android system, and then the framework layer calls an adaptation (supplicant) layer, and the supplicant layer preferentially selects a wireless network with a frequency band of 5GHz in the wireless network to connect according to factors such as signal-to-noise ratio, throughput and the like through a strategy configured in the supplicant layer.

It can be known that the wall penetrating capacity of the wireless network in the 5GHz band is lower than that of the wireless network in the 2.4GHz band, and the network stability of the wireless network in the 5GHz band is poor under the condition that a wall exists between a router and a television, and the supplicant layer preferentially selects the wireless network in the 5GHz band in the wireless network for connection, so that the problem of blocking exists when a user watches an online video through the television, and the network experience of the user is affected.

In view of the above problems, embodiments of the present application provide a network connection method of an electronic device and an electronic device, where the method may obtain at least one wireless network information after obtaining an operation instruction input by a user, and determine a network to be connected in the at least one wireless network information; then, in the case that the network to be connected comprises a first wireless network and a second wireless network, determining an alternative wireless network based on the first wireless network and the second wireless network; and connecting the target wireless network under the condition that the signal quality of the alternative wireless network is lower than the first preset signal quality. The target wireless network is a wireless network with different frequency bands from those of the alternative wireless network in the network to be connected. Therefore, after the electronic equipment determines the alternative wireless network, if the signal quality of the alternative wireless network cannot meet the requirement, the wireless network with different frequency bands from the frequency band of the alternative wireless network in the network to be connected is connected, so that the network connection stability of the electronic equipment can be improved, and the network experience of a user is improved.

Based on the electronic device having the above hardware structure or software structure, the embodiments of the present application provide a network connection method that may be implemented in the electronic device having the above hardware structure or software structure. In the following embodiments, the network connection method provided in the embodiments of the present application will be described by taking the electronic device as an example of the television 300.

The embodiment of the application provides a network connection method of an electronic device, as shown in fig. 6, the network connection method of the electronic device may include S501-S505.

S501, the television 300 receives an operation instruction input by a user.

The user may input an operation requesting connection to the wireless network to the control apparatus 200. The operation may be, for example, a pressing operation of at least one key in the remote controller by the user, or a voice operation of the television 300 by the user. The control device 200 receives and responds to the operation, generates an instruction to connect to the wireless network, and transmits the instruction to the television 300. The television 300 may receive the instruction sent by the control device 200 in the on state.

In some embodiments, if the wireless network connection function of the television 300 is turned on, S501 is not required to be executed.

It should be noted that, in the embodiment of the present application, the television 300 obtains the wireless network information through the router, and is connected to the wireless network through the router. The embodiment of the application does not limit the frequency band quantity and the frequency band type of a plurality of wireless network frequency bands supported by the router, and with the development of wireless network technology, the router can support wireless networks with more quantity or more frequency bands in future. The following embodiments are exemplified by the router supporting two frequency bands, including the 5GHz and 2.4GHz bands, i.e., the first wireless network has a frequency band of 2.4GHz and the second wireless network has a frequency band of 5GHz.

S502, the television 300 acquires at least one piece of wireless network information; wherein the wireless network information includes a wireless network name.

The television 300 obtains at least one wireless network information based on the instruction of the operation instruction in response to the operation instruction received in S501, or obtains at least one wireless network information based on the history network connection information in a state where the wireless network connection function is turned on after the television 300 is turned on.

In some embodiments, the television 300 may be scanned to obtain at least one wireless network information. Wherein each wireless network information includes a wireless network name, which may be a service set identifier (Service Set Identifier, SSID), i.e., each wireless network information corresponds to a router.

Illustratively, after the television 300 opens the wireless network connection function through the ClientModeImpl class, the ScanRequestProxy class may be invoked to obtain the SSID of each router, thereby obtaining at least one wireless network information.

In some embodiments, the wireless network connection function may be turned on or off manually based on an operation instruction input by a user, or may be turned on or off automatically based on the on/off of the television 300. Such as: after the television 300 is turned on, the WiFi connection function is automatically turned on.

Illustratively, the operation instruction includes an on instruction for requesting the television 300 to start the wireless network connection function, and after the television 300 starts the wireless network connection function in response to the on instruction, the television 300 will execute S502 to acquire at least one wireless network information.

S503, the television 300 determines a network to be connected in at least one wireless network information.

After the television 300 obtains the at least one wireless network information, the controller 350 in the television may be controlled to determine the network to be connected from the at least one wireless network information according to the operation instruction or the historical network connection information.

In some embodiments, the network to be connected refers to a wireless network having the same wireless network information as the preset wireless network information. Wherein, the preset wireless network information may be determined based on an operation instruction input by a user, or the preset wireless network information may be determined based on historical network connection information.

For example, the television 300 compares the preset wireless network information with each of the at least one wireless network information, and if the wireless network name in the wireless network information 1 is the same as the wireless network name in the wireless network information selected by the user, the wireless network corresponding to the wireless network information 1 is the network to be connected.

In some embodiments, the operation instructions include selection instructions for selecting a network to be connected; the controller is specifically configured to: the television 300 determines a network to be connected among at least one wireless network information in response to the selection instruction.

Illustratively, when a user presses at least one key in the remote controller to select one of the wireless network information from the at least one wireless network information to input a selection instruction to the television 300, after the television 300 executes S501 to obtain the selection instruction, S502 and S503 are executed to determine a network to be connected from the at least one wireless network information according to the wireless network information corresponding to the selection instruction.

In some embodiments, the television 300 determines a network of the at least one wireless network information that is the same as the historical network connection information as the network to be connected according to the historical network connection information.

Illustratively, after the television 300 is turned on, in a case where the wireless network connection function is turned on, S502 is performed to acquire at least one wireless network information, and S503 is performed to determine a network to be connected from the at least one wireless network information.

In some embodiments, the network to be connected may be one or more. In the case that there is only one network to be connected, if the network to be connected comes from the single-frequency router, the television 300 calls the supper layer, and is connected with the network to be connected based on a first policy in the supper layer; if the network to be connected is from the dual-band unified router, the television 300 invokes the frame layer, and performs S505 and S506 based on the second policy in the frame layer, so as to select the wireless network to be connected and connect.

If the plurality of networks to be connected are all from the single-frequency router, the television 3 calls a supplicant layer, and selects the network to be connected from the plurality of networks to be connected according to the signal quality (such as signal to noise ratio and throughput) of the wireless network based on a first strategy in the supplicant layer; if the to-be-connected network 1 exists in the plurality of to-be-connected networks, the to-be-connected network 1 is from the dual-frequency integrated router, the television 3 invokes the frame layer, and executes S505 or S506 based on the second policy in the frame layer, so as to select the wireless network to be connected and connect. The first policy is a native policy of the supplicant layer in the prior art, and this embodiment is not described herein again.

As shown in fig. 7, after the tv set 300 performs S502 and S503, the application layer of the software system of the tv set 300 issues the wireless network name (e.g., SSID), password, and encryption (e.g., WPA2 or WPA 3) to the frame layer, and the tv set 300 performs S504, i.e., the tv set 300 determines whether each network to be connected is from the dual-band one router through the frame layer. If the networks to be connected are all from the single-frequency router, the framework layer calls a supper layer, and the supper layer selects a wireless network to be connected from a plurality of networks to be selected based on a first strategy according to factors such as signal-to-noise ratio and throughput of the wireless network; if the to-be-connected network from the dual-frequency integrated router exists in the to-be-connected network, the frame work layer selects the wireless network to be connected from the wireless networks with different frequency bands in the to-be-connected network according to the signal strength of the wireless network based on a second strategy.

In some embodiments, the second policy in the frame work layer supports two cases: the television 300 performs S502 to S506 based on the history network connection information, and the television 300 performs S502 to S506 in response to an operation instruction input by the user.

Illustratively, when the television 300 executes S502-S506 in response to the operation instruction, the second policy in the frame layer includes: the application layer calls the Connect method of the WiFi main service (WiFi servicel) through the Connect method of the WiFi manager (WiFi manager) to start the WiFi servicel. Then, the update beforeconnect and enableNetwork methods of the wificonfigmanaager are called by the connectitonetwork method of the connectihelter to enable WiFi, i.e., to turn on the wireless network connection function of the television 300. After the wireless NETWORK connection function of the television 300 is turned on, the frame layer scans routers within a scanning range by a connectinetwork method of a connectieclievent Modem manager class to obtain at least one wireless NETWORK information, and sends a message CMD_CONNECT_NETWORK to a clientModeSimpl class to call a connectiToUserSelectnetwork method in the clientModeSimpl class. And determining a network to be connected according to the wireless network information selected by the user by a connectiToUserSelectnetwork method, and selecting a wireless network to be connected from the wireless networks of at least two frequency bands under the condition that the network to be connected comprises the wireless networks of at least two frequency bands. Finally, the method is connected with the selected wireless network needing to be connected by calling the StartConnectToNetwork method of the ClientModeSimpl class.

When the network to be connected only comprises wireless networks with the same frequency band, the frame layer sets a basic service set identifier (Basic Service Set Identifier, BSSID) of the network to be connected to be null, and carries the BSSID set to be null to the CMD_START_CONNECT to be sent to the connectiToNetwork, so that the frame layer calls a connectiToNetwork method in the WiFiNative class and a connectToNetwork, addNetworkAndSaveConfig, addNetwork method in the supplicantStaifanceHal to realize communication with the Supplicant layer. After the framework layer establishes communication with the Supplicant layer, the Supplicant layer selects a wireless network to be connected through a selection method in Supplicant staifancehal, after the network to be connected is selected, a setb ssid method in Supplicant stanetworkhal class is called, and the wireless network to be connected is selected to reset the BSSID set to be empty according to the selected wireless network to be connected, and then the Supplicant layer is connected with the wireless network to be connected according to the set BSSID.

In the startconnectittonetwork method, the frame layer defaults the BSSID to any value, so that when the application layer issues the BSSID to the frame layer, the frame layer will not connect to the wireless network according to the BSSID.

When the television 300 performs S502-S506 based on the historical network connection information, the second policy in the frame work layer further includes: the application layer calls a Connect method of a main service (WiFiServiceI) of the WIFI through a Connect method of a WiFi manager (WiFiManager) to start the WiFiServiceI, and then records connected wireless network information (such as a wireless network name and a password) into a WiFiConfigStore.xml file through an addOrUpdatanetwork method of the WiFiConfigManager class to generate historical connection network information; after the television 300 is turned on, if the wifiservicel is started, the WiFiConnectivityManager class will call the startconnectitonetwork method of the ClientModeImpl class through the historical connection network information recorded in the wificonnectigstore.

S504, in a case where the network to be connected includes the first wireless network and the second wireless network, the television 300 determines an alternative wireless network based on the first wireless network and the second wireless network. The wireless network names of the first wireless network and the second wireless network are the same, and the frequency bands of the first wireless network and the second wireless network are different.

After the television 300 determines the network to be connected, it determines whether the network to be connected includes the first wireless network and the second wireless network, and determines an alternative wireless network from the first wireless network and the second wireless network in the case where the network to be connected includes the first wireless network and the second wireless network. The wireless network names of the first wireless network and the second wireless network are the same, and the frequency bands of the first wireless network and the second wireless network are different.

For example, the wireless network names of the first wireless network and the second wireless network are network 1, but the frequency band of the first wireless network is 5GHz, and the frequency band of the second wireless network is 2.4GHz.

In some embodiments, since the dual-band unification function of the router can set the wireless network names, passwords, encryption modes and the like of the wireless networks of the frequency bands supported by the router to be the same, if the network to be connected does not include the first wireless network and the second wireless network, the network to be connected comes from the single-band router; if the network to be connected comprises a first wireless network and a second wireless network, the network to be connected comes from the dual-frequency integrated router.

Further, the step S504 may include: and determining the wireless network with the same frequency band as the preset frequency band in the first wireless network and the second wireless network as an alternative wireless network based on the frequency band of the first wireless network and the frequency band of the second wireless network.

The television 300 determines an alternative wireless network according to the preset frequency band, and the frequency band of the first wireless network and the frequency band of the second wireless network, and determines a wireless network with the same frequency band as the preset frequency band in the first wireless network and the second wireless network as the alternative wireless network.

In some embodiments, the television 300 detects a frequency band of the first wireless network, and determines that the first wireless network is an alternative wireless network if the frequency band of the first wireless network is the same as the preset frequency band; if the frequency band of the first wireless network is different from the preset frequency band, the second wireless network is determined to be an alternative wireless network.

For example, if the preset frequency band is set to be 5GHz, the television 300 detects the frequency band of the first wireless network, and determines that the frequency band of the first wireless network is 2.4GHz, then the second wireless network is determined to be an alternative wireless network.

In some embodiments, after the television 300 determines the alternative wireless network, S505 is performed. If the frequency band of the first wireless network and the frequency band of the second wireless network are different from the preset frequency band, the television 300 sends out error reporting information and displays the error reporting information through a display.

S505, the television 300 is connected with the target wireless network under the condition that the signal quality of the alternative wireless network is lower than the first preset signal quality; the target wireless network is a wireless network with different frequency bands from those of the alternative wireless network in the network to be connected.

After determining the alternative wireless network, the television 300 determines whether the signal quality of the alternative wireless network is lower than a first preset signal quality, and connects to the target wireless network if the signal quality of the alternative wireless network is lower than the first preset signal quality; and connecting the alternative wireless network under the condition that the signal quality of the alternative wireless network is higher than or equal to the first preset signal quality. If S504 is executed, it is determined that the candidate wireless network is the first wireless network, and the target wireless network is the second wireless network; if S504 is performed to determine that the alternative wireless network is the second wireless network, the target wireless network is the first wireless network.

In some embodiments, if S504 is executed to determine that the alternative wireless network is the first wireless network, the television 300 detects the signal quality of the first wireless network, and if the signal quality of the first wireless signal is lower than the first preset signal quality, the television 300 is connected to the second wireless network; in the case that the signal quality of the first wireless signal is higher than or equal to the first preset signal quality, the television 300 is connected to the first wireless network.

Illustratively, the signal quality may include: any one or more of reference signal received power (Reference Signal Received Power, RSRP), reference signal received quality (Reference Signal Received Quality, RSRQ), received signal strength indication (Received Signal Strength Indication, RSSI), and signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR). The SINR refers to the ratio of the strength of the received useful signal to the strength of the received interfering signal (noise and interference).

In some embodiments, the frequency band of the alternative wireless network comprises 5GHz and the frequency band of the target wireless network comprises 2.4GHz.

Illustratively, if the first wireless network is 5GHz and the second wireless network is 2.4GHz, the first wireless network is an alternative wireless network and the second wireless network is a target wireless network.

In some embodiments, the signal quality may be signal strength with a preset frequency band of 5 GHz. The first predetermined signal quality may be a signal strength of-88 dbm. The first preset signal quality may be determined based on experimental results.

Fig. 8 is a schematic diagram of wall penetration capability of a wireless network with different frequency bands sent by a dual-band integrated router, as shown in fig. 8, because the frequency of the wireless network with the frequency band of 2.4GHz is low and the wavelength is longer than that of the wireless network with the frequency band of 5GHz, the attenuation is relatively less when the wireless network with the frequency band of 2.4GHz passes through an obstacle, so that the propagation distance is farther than that of the wireless network with the frequency band of 5GHz, the frequency bandwidth of the wireless network with the frequency band of 5GHz is wider, and electronic products corresponding to the wireless network with the frequency band of 5GHz are fewer, so that the wireless network with the frequency band of 5GHz suffers less interference, the network speed is stable, namely the wireless network with the frequency band of 5GHz has poorer wall penetration capability, and the wireless network with the frequency band of 2.4GHz has stronger wall penetration capability. It is understood that the router and television 300 are in one room, and the wireless network with the frequency band of 5GHz is faster than the wireless network with the frequency band of 2.4GHz.

Based on the above principle, fig. 9 provides an experimental scenario of the wall-penetrating capability of the wireless network with different frequency bands, and in the following embodiment, experiments are performed based on the experimental scenario shown in fig. 9, and the first preset signal quality in S505 can be determined according to the experimental result.

The signal strength from the router is illustratively tapered by a signal attenuator to simulate the scene of a partition between the router and the television 300. And then, based on the scene of the partition wall between the router and the television 300 and the scene that the router and the television 300 are located in the same room, the signal quality of the wireless network (2.4 GWiFi) with the frequency band of 2.4GHz and the signal quality of the wireless network (5 GWiFi) with the frequency band of 5GHz are counted, so that the first preset signal quality is determined.

The connection mode between the television 300 and the wireless network with the frequency band of 5GHz or the wireless network with the frequency band of 2.4GHz may be that the user clicks to connect with WiFi, the television 300 is connected with the wireless network, that is, the television 300 is connected with the wireless network based on the operation instruction; or the television 300 can be automatically connected back to the wireless network after being powered on, that is, the television 300 is connected to the wireless network based on the historical network connection information.

In the experimental process, the signal intensity of the wireless network scanned by the television 300 is counted, meanwhile, the online video is played in real time, and whether the online video is blocked or not is observed to obtain the experimental result. From the experimental results, it can be found that: when the signal intensity of the wireless network with the frequency band of 5GHz is attenuated to-88 dbm, the online video is played very stuck, and when the signal intensity of the wireless network with the frequency band of 2.4GHz is attenuated to-88 dbm, the playing is still smooth; i.e., after the partition between the router and the tv 300, the signal strength would be unstable if it was attenuated to-88 dbm, at which time a 2.4G network should be selected. Thus, the first predetermined signal quality is a signal strength of-88 dbm.

As shown in fig. 10, in some embodiments, in the network connection method of an electronic device provided in the present application, S506 is further included after S504.

S506, connecting the alternative wireless network under the condition that the signal quality of the alternative wireless network is higher than the second preset signal quality; wherein the second preset signal quality is higher than or equal to the first preset signal quality.

After determining the alternative wireless network, the television 300 determines whether the signal quality of the alternative wireless network is lower than the first preset signal quality, and connects the alternative wireless network if the signal quality of the alternative wireless network is higher than the second preset signal quality.

For example, if S504 is executed to determine that the alternative wireless network is the first wireless network, the television 300 detects the signal quality of the first wireless network, and if the signal quality of the first wireless signal is higher than or equal to the second preset signal quality, the television 300 is connected to the first wireless network.

As shown in fig. 11, in some embodiments, the method for network connection of an electronic device provided in the present application further includes S507 after S505.

S507, connecting the alternative wireless network when the connection failure times of the target wireless network are larger than or equal to the preset times.

When the television 300 performs S506, if the number of connection failures of the target wireless network is greater than or equal to the preset number, the television 300 connects to the alternative wireless network.

By way of example, the number of connection failures may be 3. The connection failure determination rule may be that a duration of the connection of the television 300 to the target wireless network exceeds a preset time, that is, the connection of the television 300 to the target wireless network is overtime.

In some embodiments, as shown in fig. 12, in the case where the television 300 performs S505, the supper layer may generate a connection timeout, and at this time, the supper layer will report the connection timeout to the wifi monitor class through the supper staifancecallbackimpl class. The WiFiMonitor class then sends notification information to the ClientModeCommpl class to notify the ClientModeCommpl class to perform connection timeout counting to obtain the connection timeout times. And finally, judging whether the connection timeout times are more than 3 times, if so, selecting to connect the 5GHz wireless network, namely the connection target wireless network, and if not more than 3 times, continuing to attempt to connect the 2.4GHz wireless network, namely the connection candidate wireless network.

In some embodiments, the present embodiment further provides another network connection method of an electronic device, as shown in fig. 13, where the network method of the other electronic device includes S601-S613.

S605, storing WiFi with the same name as the WiFi to be connected in the policy list.

S606, invoking WiFi with the same name as the WiFi to be connected currently from the strategy list, judging whether two identical SSIDs (a first wireless network and a second wireless network) exist in the WiFi, if yes, executing S607, and if not, executing S612 and S613.

S607, one of the two identical SSIDs in S606 is called.
