Wireless network access method and device

Technical Field

Background

Currently, most intelligent terminal devices have a wireless network communication function, and a user can select a plurality of wireless network access modes, typically, for example, WI-FI hotspot access, a 4G network, a 5G network, and the like. Different wireless network access modes naturally have different advantages, but opening multiple wireless network access modes simultaneously can cause the increase of equipment power consumption, especially to some small-size smart machines.

In the related art, the wireless network access modes are usually manually turned on or turned off by a user, and in many cases, switching is not performed after a plurality of wireless access modes are simultaneously turned on. In this case, the simultaneous turning on of multiple wireless network access modes causes an increase in power consumption of the device.

In the embodiment of the application, at least one of the plurality of wireless networks can be disconnected according to the running state of the terminal equipment and NAT timeout duration parameters of the plurality of wireless networks accessed in the terminal equipment. The time-out duration parameter of the wireless network is in positive correlation with the time interval of the heartbeat packets sent by the terminal equipment, and the longer the time-out duration is, the longer the terminal equipment can maintain the long connection with the server by using fewer heartbeat packets in the same time, and the electricity consumption of the terminal equipment can be saved by sending fewer heartbeat packets. On the other hand, the embodiment of the application also judges whether to disconnect the wireless network according to the running state of the terminal equipment, and only under the running state of the terminal equipment meeting the preset condition, part of the wireless network can be disconnected. Therefore, the wireless network access mode provided by the embodiment of the application can optimize the power consumption of the terminal equipment.

and under the condition that the application utilizes the second wireless network for network communication, the second wireless network is disconnected after the application finishes the service or suspends the service.

In this embodiment, when it is determined that there is a large flow application performing a large flow service using a second wireless network to be disconnected, the second wireless network may be disconnected after the application completes or suspends the large flow service, so as to prevent the application from being switched to a wireless network with a limited flow, which results in economic loss for a user.

According to a fifth possible implementation manner of the first aspect, the disconnecting at least one of the plurality of wireless networks includes:

and under the condition that the application utilizes the first wireless network to carry out network communication, the first wireless network does not limit the flow, and the second wireless network is disconnected.

In this embodiment, under the condition that it is determined that the switched wireless network does not limit the flow, the operation of the large-flow application is not affected, and the optimization of the power consumption does not need to be delayed.

Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present application. It will be understood by those skilled in the art that the present application may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present application.

In order to facilitate those skilled in the art to understand the technical solutions provided in the embodiments of the present application, a technical environment for implementing the technical solutions is first described below.

The terminal equipment needs to have a public network IP address when accessing the Internet, and the public network IP address has uniqueness in the global Internet. Because the number of public Network IP addresses is limited, and the public Network IP addresses are in a serious shortage state at present, a Network operator can provide an intranet IP for a user, and a plurality of terminal devices in the intranet can share one public Network IP through a Network Address Translation (NAT) protocol. Therefore, the main function of the NAT protocol is to map the intranet IP address of the terminal device to the extranet IP address, so that the terminal device can access the internet. However, the number of terminal devices served by the same network operator is huge, and in order to reduce the link load of the gateway and save the channel resources, the network operator makes the following settings: if the communication network link of the terminal equipment does not communicate for a period of time, the network link communication of the terminal equipment is disconnected, and meanwhile, the mapping relation between the intranet IP address and the extranet IP address is deleted, so that a network operator can provide the intranet IP address for other users to use.

However, many terminal device applications need to maintain a long-time connection with the backend server to acquire the messages pushed by the backend server. For example, even if the mobile phone is in the off-screen state, the user still needs to receive messages of an application such as WeChat. Based on the method, the long TCP connection can be established between the terminal equipment and the server, and the effectiveness of the long TCP connection is maintained by utilizing a heartbeat mechanism. In the heartbeat mechanism, the terminal device may send a custom message, which may also be referred to as a heartbeat packet, to the server at intervals. After receiving the heartbeat packet, the server may also return a customized message to the terminal device, which may also be referred to as a heartbeat response. As described above, the network operator sets that if the communication network link of the terminal device does not communicate for a period of time, the network operator disconnects the network link communication of the terminal device, and the period of time may become the NAT timeout duration. Based on this, the interval of sending the heartbeat packet to the server by the terminal device can be set to be slightly less than the NAT timeout duration, and has positive correlation with the NAT timeout duration.

In order to maintain connection with the background server, the application in the terminal device needs to send a heartbeat packet to the background server for a long time and receive a reply sent by the background server. The communication between the application and the background server may use various wireless networks, and the use of various wireless networks requires different communication modules in the terminal device to operate simultaneously, which results in more power consumption.

The following describes an application scenario environment according to an embodiment of the present application with reference to an actual application scenario.

In the process of using an intelligent terminal device (such as a smart phone and an intelligent wearable device), in order to ensure that the terminal device is continuously networked, a user often simultaneously starts multiple Wireless network access modes, such as a cellular network and a Wireless Fidelity (Wi-Fi) network. Based on the above description of the technical environment, even if the terminal device is in the screen-off state, the terminal device needs to continuously send heartbeat packets to the server to maintain a long connection with the server. However, the sending of the heartbeat packet and the receiving of the reply message from the server consume power, and therefore, the user finds that the power consumption of the intelligent terminal device is large even when the intelligent terminal device is not used. To the less intelligent wearing equipment of some electric storage quantities, like intelligent bracelet, intelligent wrist-watch, intelligent glasses etc. the electric quantity consumption of this part can not be ignored.

Based on the actual technical requirements similar to those described above, the wireless network access method provided by the application can respectively obtain the NAT timeout durations corresponding to the multiple wireless network access methods, and disconnect a part of wireless networks according to the NAT timeout durations. In this way, the terminal device can maintain a long connection with the server by sending fewer heartbeat packets, which can consume less power.

The technical scheme that this application embodiment provided can be applied to the terminal equipment that can insert multiple wireless network, terminal equipment can include smart phone, computer (including notebook computer, desktop computer), dull and stereotyped electronic equipment (like panel computer, electronic reader), Personal Digital Assistant (PDA), wearable electronic equipment (like intelligent bracelet, intelligent wrist-watch, intelligent glasses), intelligent household electrical appliances (sweep floor robot, TV, virtual reality equipment, air conditioner, refrigerator, lamps and lanterns, projecting apparatus, audio amplifier etc.). The Wireless Network includes a Wireless Local Area Network (WLAN), a Wireless Wide Area Network (WWAN), a Wireless Metropolitan Area Network (WMAN), and a Wireless Personal Area Network (WPAN). The WLAN may include, among other things, a network that provides wireless communication access over short distances, such as a Wi-Fi network. The WWAN may include a wireless communication network, such as a 2G/3G/4G/5G wireless network, provided over a mobile communication infrastructure. WMANs allow access users to access a fixed-site wireless network that connects multiple fixed sites in a city or region. The WPAN is a wireless network in which a portable device owned by a user person is wirelessly connected in a short distance via a communication device. The application does not limit the types of the terminal equipment and the wireless network.

An embodiment of the present application provides a wireless network access method, and specifically, as shown in fig. 1, the wireless network access method may include:

s101: the method comprises the steps of obtaining the running state of terminal equipment, wherein the terminal equipment is connected with a plurality of wireless networks simultaneously.

The method of the embodiment of the application can be applied to terminal equipment which is simultaneously accessed to a plurality of wireless networks, wherein the plurality of wireless networks can comprise two or more wireless networks. Fig. 2 shows a schematic diagram of terminal device 101 communicating with server 104, server 105, and server 106 using wireless network 102 and wireless network 103.

In the embodiment of the application, the running state of the application in the terminal equipment has an association relation with whether at least one wireless network needs to be disconnected. The operating state may include at least one of: whether the terminal equipment runs in a foreground or a background, flow use information applied in the terminal equipment, the working mode of the terminal equipment, the electric quantity information of the terminal equipment and the network information of the plurality of wireless networks.

In an embodiment of the application, the state information of whether the terminal device operates in the foreground or the background can be acquired. For the terminal device with the display screen, the terminal device running in the background may include that the terminal device is in a screen-off state, and running in the foreground may include that the terminal device is in a screen-on state. The screen-off of the display screen of the terminal device may refer to a scene in which the display card in the terminal device does not draw the user interface. Of course, in the screen-off scene, the terminal device or the application in the terminal device may run in the background, such as playing music and monitoring sleep. Of course, in other embodiments, the terminal device running in the background may further include an application that is not running in the terminal device, and the like, which is not limited herein.

The traffic usage information of the application in the terminal device may include a speed at which the application consumes traffic and a connected wireless network. In some examples, a video application in the terminal device is downloading video by using a Wi-Fi network at a downloading speed of 2M/s, and a photo application in the terminal device synchronizes photos, videos and other data by using the Wi-Fi network at an uploading speed of 810 k/s. It should be noted that, the traffic of each application in the terminal device may be determined by a traffic statistic component in the terminal device, so as to determine the application in the terminal device whose traffic is greater than the preset traffic threshold. For example, in an Android operating system, traffic statistics can be performed on the terminal device and each application in the terminal device through TrafficStats.

The operation mode of the terminal device may include one of a plurality of operation modes preset by the terminal device, for example, the operation mode may include an airplane mode, a low battery mode, a normal mode, and the like. Under a preset working mode, the terminal equipment can operate according to preset operation parameters. Of course, the preset operation mode is different for different terminal devices, and is not limited herein.

The power information of the terminal device may include at least one of a power value of the terminal device, a power consumption rate, whether charging is in progress, a charging rate, a battery capacity of the terminal device, and the like. The power information may be obtained from a battery management module in the terminal device.

The network information of the plurality of wireless networks may include signal information, function information, and the like of the plurality of wireless networks. The signal information may further include signal strength, signal stability, and the like. The signal stability may also include parameters such as signal noise, retry rate, and line break rate. The capability information may include whether the wireless network is associated with a necessary function in the terminal device, etc.

It should be noted that the operation status is not limited to the above example, and any status information related to power consumption optimization of the terminal device and disconnection of the wireless network belongs to the protection scope of the present application, and other modifications are possible for those skilled in the art in light of the technical spirit of the present application, but should be covered by the protection scope of the present application as long as the functions and effects achieved by the present application are the same as or similar to those of the present application.

S103: and acquiring NAT (network Address translation) timeout durations respectively corresponding to the wireless networks, wherein the NAT timeout durations comprise the longest duration for keeping connection of network links established by the wireless networks under the condition that communication does not occur.

In this embodiment of the application, the NAT timeout duration may include the longest duration for the network link established by the wireless network to maintain connection without communication, that is, the wireless network is disconnected when the duration for the network link established by the wireless network to not communicate is greater than the NAT timeout duration. The network link not communicating in this embodiment may include the network link not transmitting data.

In an embodiment of the present application, the NAT timeout duration may be obtained by sending a heartbeat packet to a server. Fig. 3 shows a flowchart of a method for obtaining NAT timeout duration for a wireless network. After determining which wireless network to use to establish a network link with the server, an initial value of the NAT timeout period may be obtained, and the initial value may be set to 30s, 35s, 40s, and so on. Then, the terminal device may send a heartbeat packet to the server through the network link, and start a timer, where the timing duration is the initial value. In the case that the timer expires, it may be determined whether the network link is disconnected. Under the condition that the network link is disconnected, the set initial value is too high, so that the wireless network can be used again to send the heartbeat packet to the server, the timer is started, the timing duration is reduced by 10s on the basis of the initial value, and of course, 10s is only used as a reference value, and is not limited herein. Otherwise, under the condition that the network link is kept connected, the set initial value is too low, so that the heartbeat packet can be sent to the server by using the wireless network again, the timer is started, and the timing duration is increased by 10s on the basis of the initial value. Thus, the above process may be repeatedly executed until the network link keeps connected for many times in the same timing duration, and the timing duration may be used as the NAT timeout duration. The method for determining the NAT timeout duration provided by the embodiment can be applied to wireless signals with large differences among different areas or unstable signals.

Of course, in other embodiments, the NAT timeout duration may also be obtained from a wireless network operator, for example, the NAT timeout duration obtained for a certain operator is 4 min. In addition, the NAT timeout duration of the history record can be obtained according to a user log in the terminal device, and the NAT timeout duration obtaining method is not limited.

S105: when the operating state of the terminal equipment and the NAT timeout duration respectively corresponding to the plurality of wireless networks meet the preset conditions, disconnecting at least one wireless network in the plurality of wireless networks, wherein the operating state of the terminal equipment and the NAT timeout duration respectively corresponding to the plurality of wireless networks meet the preset conditions and comprise the following steps: the terminal equipment operates in a background, the NAT timeout duration corresponding to a first wireless network in the wireless networks is longer than the NAT timeout duration corresponding to a second wireless network, and at least one wireless network is the second wireless network.

In an embodiment of the application, the determining that the operating state of the terminal device and the NAT timeout durations respectively corresponding to the plurality of wireless networks meet a preset condition includes: and judging whether the running state of the terminal equipment and NAT timeout duration respectively corresponding to the plurality of wireless networks meet preset conditions or not.

In this embodiment, the preset condition may include a condition for turning off at least one of the plurality of wireless networks. According to the description of the technical environment, the time interval of sending the heartbeat packet by the terminal equipment has positive correlation with the NAT timeout duration, and the longer the NAT timeout duration is, the longer the time interval of sending the heartbeat packet is. In one example, the obtained NAT timeout duration corresponding to the Wi-Fi network is 20s, and the NAT timeout duration corresponding to the 4G cellular mobile network is 35 s. Therefore, the time interval for sending the heartbeat packets by using the Wi-Fi network is smaller than the time interval for sending the heartbeat packets by using the 4G cellular mobile network. That is, the terminal device can send fewer heartbeat packets to maintain a long connection with the server using the 4G cellular mobile network during the same time. Based on this, in an embodiment of the present application, for the NAT timeout duration, the determining whether the NAT timeout durations respectively corresponding to the plurality of wireless networks meet a preset condition includes:

and judging whether the difference between the NAT timeout durations respectively corresponding to the wireless networks is greater than a preset duration threshold value or not.

In the embodiment of the application, at least one of the wireless networks is disconnected under the condition that the difference between the NAT timeout durations of the wireless networks is greater than the preset duration threshold. For example, in the above example, the NAT timeout durations corresponding to the Wi-Fi network and the 4G cellular mobile network are 20s and 35s, respectively, and the difference between the two is large, and the Wi-Fi network with the shorter timeout duration needs to be disconnected. On the contrary, if the NAT timeout durations of the two wireless networks are both 25s, the power consumption generated by the terminal device is the same no matter which wireless network is used for communication. In the embodiment of the present application, the preset duration threshold may be set to 3s, 4s, 5s, and the like.

The preset conditions corresponding to the different operation states provided in S101 are described below.

In an embodiment of the application, for the case that the operation state includes whether the terminal device operates in the background, the determining whether the operation state of the terminal device meets a preset condition may include:

and judging whether the terminal equipment runs in the background or not.

In this embodiment, in order to make the operation of disconnecting the wireless network imperceptible to the user, the network may be disconnected when the terminal device operates in the background. In one example, at least one wireless network may be disconnected in a terminal device off-screen state.

In an embodiment of the present application, for the case that the operation state includes traffic usage information applied in a terminal device, determining whether the operation state of the terminal device meets a preset condition includes:

and judging whether the terminal equipment runs the application with the flow larger than a preset flow threshold value or not according to the flow use information of the application in the terminal equipment.

In an actual scene, charging modes of different wireless networks are different, generally, a Wi-Fi network does not limit traffic, a 4G/5G cellular mobile network often needs to limit traffic, and certainly, according to a traffic package type selected by a user, some package types need to limit traffic, and some do not need to limit traffic. And determining whether the terminal equipment has an application with the flow larger than a preset flow threshold value according to the flow information applied in the terminal equipment. For example, before the Wi-Fi network is disconnected, the flow rate of some applications in the terminal equipment using the Wi-Fi network is determined to be greater than a preset flow rate threshold value, and the preset flow rate threshold value can be set to be 200k/s, 300k/s, 500k/s and the like. In some examples, there are some video applications in the terminal device to download video, photo applications to synchronize data such as photos or video, etc., and these applications need to consume large amount of traffic. In the case where there is an application of the above type that relies on wireless network communications to be disconnected, if the wireless network is suddenly disconnected, there is a high possibility that switching to another wireless network with traffic limitation will cause economic loss to the user.

In an embodiment of the application, for the case that the running state includes traffic usage information applied in a terminal device, the determining whether the running state of the terminal device meets a preset condition includes:

judging whether an application with the flow larger than a preset flow threshold value runs in the terminal equipment or not according to the flow use information of the application in the terminal equipment;

and under the condition that the application with the flow rate larger than the preset flow rate threshold value runs in the terminal equipment, judging whether the wireless network used by the application limits the flow rate.

In the embodiment of the application, under the condition that the large-flow application is determined to run in the terminal device, whether the switched wireless network limits the flow can be determined. The wireless network may be turned off upon determining that the switched wireless network does not need to restrict traffic. For example, the Wi-Fi network is disconnected according to the NAT timeout duration, but a lot of large-flow applications in the terminal equipment are monitored to run, and according to the setting of the terminal equipment, the terminal equipment is automatically switched to the 4G cellular mobile network under the condition that the Wi-Fi network is disconnected. Therefore, whether the 4G cellular mobile network needs to limit the flow can be determined, the Wi-Fi network can be immediately disconnected under the condition that the 4G cellular mobile network does not limit the flow, the Wi-Fi network does not need to be disconnected after the high-flow application is finished, and therefore the running of the high-flow application is not influenced, and the optimization of the power consumption does not need to be delayed. In the embodiment of the application, the terminal device may acquire information of the cellular mobile network of the user from a cellular mobile network operator, for example, acquire that the user purchases an unlimited flow package, so that closing the wireless network with a short NAT timeout duration causes the terminal device to be switched to another wireless network, and thus, economic loss of the user is not caused.

and judging whether the terminal equipment operates in a low-power working mode or not according to the working mode of the terminal equipment.

In the embodiment of the application, under the condition that the terminal device operates in the low-power operating mode, it can be stated that the terminal device needs to perform power optimization to reduce the power consumption speed of the terminal device.

In an embodiment of the present application, for the fact that the operation state includes traffic usage information applied in a terminal device, the determining whether the operation state of the terminal device meets a preset condition includes:

the judging whether the running state of the terminal equipment meets a preset condition or not comprises the following steps:

judging whether the electric quantity of the terminal equipment is smaller than a preset electric quantity threshold value or not according to the electric quantity information of the terminal equipment;

or the electric quantity consumption speed of the terminal equipment is greater than a preset electric consumption threshold value;

or the electricity consumption speed of the terminal equipment is greater than the charging speed.

In the embodiment of the application, the optimization of the electric quantity is started from the requirement of electric quantity optimization, namely, under the scene that the electric quantity of the terminal equipment is small or the power consumption speed is high.

In an embodiment of the application, for the case that the operation status includes network information of the plurality of wireless networks, the determining whether the operation status of the terminal device meets a preset condition includes:

and respectively judging whether the wireless networks are associated with the necessary functions of the terminal equipment according to the network information of the wireless networks.

In the embodiment of the application, if the wireless network is disconnected under the condition that the wireless network is associated with the necessary functions in the terminal equipment, the necessary functions cannot be realized in the terminal equipment. The necessary functions may include functions indispensable in the terminal device. For example, for a child watch, in a normal use state, a 4G cellular mobile network is generally associated with a call function, once the 4G cellular mobile network is disconnected, the call function of the child watch is also turned off, and the call function is a basic function of the child watch, and once the call function is turned off, a call cannot be answered. For a children's watch, the connected cellular mobile network is associated with the call functionality of the watch, which, if disconnected, renders the call functionality of the watch unusable.

and respectively judging whether the signal intensity of the wireless networks is greater than a preset intensity threshold value or not or whether the signal stability is greater than a preset stability threshold value or not according to the network information of the wireless networks.

In practical applications, different wireless networks consume different power at different speeds, for example, for a 4G cellular mobile network, communication with a base station requires signal transmission and signal reception, hardware consumes power at a high speed, and especially in an environment with relatively poor signals, a device may expand a search range and enhance a transmission signal, and power consumption may be further increased. The Wi-Fi network transmits and receives signals through the wireless router, and may consume less power in a relatively stable environment. For some intelligent terminal devices with simple functions, software or hardware conditions for counting power consumption of each wireless network may not be provided, for example, for the child watch, such intelligent terminal devices may only acquire some simple network parameters of the wireless network, such as signal strength. Because the signal intensity of the wireless network and the power consumption speed are in a negative correlation relationship, the stronger the signal intensity is, the slower the power consumption speed of the corresponding wireless network is; conversely, the weaker the signal strength, the faster the power consumption speed of the corresponding wireless network. Based on this, the signal strength and/or signal stability of the wireless network that remains connected can be used as a condition for further determining whether a certain wireless network needs to be shut down.

It should be noted that the implementation manner of S105 is not limited to the above embodiments, and may also include any combination of the above embodiments, and the present application is not limited herein. And if the terminal equipment is judged to be operated in the background and the flow use information of the application in the terminal equipment is judged to be operated with the application of which the flow is larger than the preset flow threshold value.

In an embodiment of the present application, the disconnecting at least one of the plurality of wireless networks when it is determined that the operation state of the terminal device and the NAT timeout durations respectively corresponding to the plurality of wireless networks meet a preset condition includes:

and under the condition that the terminal equipment operates in the background and the difference between the NAT timeout durations corresponding to the wireless networks is larger than a preset duration threshold, disconnecting at least one wireless network in the wireless networks.

In the embodiment of the application, under the condition that the terminal equipment runs in the background and the NAT timeout durations corresponding to the wireless networks have larger difference, the wireless networks can be disconnected. Fig. 4 shows an application scenario of the embodiment, in which a terminal device in the scenario is connected to three wireless networks, namely a Wi-Fi network, a 4G cellular mobile network, and a 5G cellular mobile network. After the screen is turned off, the terminal device may acquire the NAT timeout durations of the Wi-Fi network, the 4G cellular mobile network, and the 5G cellular mobile network, respectively, as shown in fig. 4, where the NAT timeout durations of the three wireless networks are 28s, 40s, and 45s, respectively. And according to the NAT timeout duration, the terminal equipment disconnects the Wi-Fi network and the 4G cellular mobile network. In addition, the wireless network disconnected in the screen-off state can be reconnected under the condition that the terminal equipment is monitored to be switched from the screen-off state to the screen-on state, and a user can not sense disconnection of the wireless network. As shown in fig. 4, after the terminal device is turned on, for example, after the alarm clock is turned on, the terminal device is connected to the Wi-Fi network and the 4G cellular mobile network again. It follows that the process is not perceived by the user.

In an embodiment of the present application, the disconnecting at least one of the multiple wireless networks when it is determined that the operating state of the terminal device and the NAT timeout durations respectively corresponding to the multiple wireless networks meet the preset condition includes:

determining at least one target wireless network to be disconnected according to the NAT timeout duration;

and determining that an application with the flow larger than a preset flow threshold value runs in the terminal equipment, and disconnecting the target wireless network after waiting for the application to finish or suspend the high-flow service under the condition that the application utilizes the target wireless network for communication.

In an example of the application, according to two networks of a Wi-Fi network and a 4G cellular mobile network connected to a terminal device, it is determined that the NAT timeout duration of the Wi-Fi network is shorter than that of the 4G cellular mobile network, and the Wi-Fi network can be used as a target wireless network to be disconnected. However, the Wi-Fi network is disconnected after video caching and photo synchronization in the terminal equipment application are determined to be completed based on the fact that the Wi-Fi network is used for carrying out large-flow data transmission by the video application and the photo application in the terminal equipment. In another embodiment, the application with higher traffic consumption can be suspended, and the unfinished work in the application can be continuously completed under the condition that the disconnected wireless network is reconnected.

determining at least one first wireless network to be disconnected and at least one reserved second wireless network according to the NAT timeout duration;

and disconnecting the first wireless network when determining that the application with the flow rate larger than a preset flow rate threshold value runs in the terminal equipment, the application utilizes the target wireless network for communication, and the second wireless network does not limit the flow rate.

In an example of the application, according to two networks, namely a Wi-Fi network and a 4G cellular mobile network, connected in a terminal device, it is determined that the NAT timeout duration of the Wi-Fi network is shorter than that of the 4G cellular mobile network, and the Wi-Fi network may be used as a first wireless network to be disconnected, and the 4G cellular mobile network may be used as a second wireless network to be reserved. However, the video application and the photo application in the terminal equipment are found to be used for carrying out large-flow data transmission by utilizing the Wi-Fi network, and whether the 4G cellular mobile network limits the flow can be judged. The Wi-Fi network may be disconnected in case the 4G cellular mobile network does not restrict traffic.

and under the condition that the terminal equipment operates in a low-power working mode and the difference between the NAT timeout durations corresponding to the wireless networks is larger than a preset duration threshold, disconnecting at least one of the wireless networks.

In the embodiment of the application, in the low power operating mode, the total power of the terminal device is less than the preset power, power optimization is required, and at least one wireless network can be disconnected. The low power operating mode may be switched by a user, or may be automatically switched by the terminal device after monitoring the total power of the device, which is not limited herein.

under the condition that the difference between the NAT timeout durations corresponding to the wireless networks is determined to be larger than a preset duration threshold and at least one of the following conditions, disconnecting at least one of the wireless networks:

the electric quantity of the terminal equipment is smaller than a preset electric quantity threshold value;

the electric quantity consumption speed of the terminal equipment is greater than a preset electric consumption threshold value;

the electric quantity consumption speed of the terminal equipment is greater than the charging speed.

In the embodiment of the application, under the condition that the electric quantity in the terminal equipment is small or the electric quantity consumption speed is high or the electric quantity consumption speed is higher than the charging speed, the fact that the terminal equipment needs to optimize the electric quantity can be determined, and therefore the electric quantity can be saved by disconnecting at least one wireless network.

disconnecting the target wireless network if it is determined that the target wireless network is not associated with a necessary function of a terminal device.

In the embodiment of the application, the wireless network is disconnected under the condition that the target wireless network is determined to have no necessary functions related to the terminal equipment. Otherwise, the connection of the wireless network may be maintained. For example, based on the comparison of the NAT timeout periods, it is determined to disconnect the 4G cellular mobile network in the child watch, but it is detected that the 4G cellular mobile network is associated with the call function in the child watch, and therefore, the connection of the 4G cellular mobile network may continue to be maintained.

and disconnecting the first wireless network under the condition that whether the signal strength of the second wireless network is greater than a preset strength threshold value and/or whether the signal stability is greater than a preset stability threshold value is determined.

In an example of the application, according to two networks, namely a Wi-Fi network and a 4G cellular mobile network, connected in a terminal device, it is determined that the NAT timeout duration of the Wi-Fi network is shorter than that of the 4G cellular mobile network, and the Wi-Fi network may be used as a first wireless network to be disconnected, and the 4G cellular mobile network may be used as a second wireless network to be reserved. And if the acquired signal strength of the 4G cellular mobile network is greater than a preset strength threshold value, the Wi-Fi network can be closed. On the contrary, if the acquired signal strength of the 4G cellular mobile network is weaker and is smaller than the preset strength threshold, the Wi-Fi network can be reserved.

Further, in another embodiment, the wireless network may consume less power in the case of greater signal strength and greater stability. Based on the above, the signal stability of the second wireless network can be obtained to judge whether the signal stability is greater than a preset stability threshold. Based on this, the first wireless network is disconnected under the condition that the signal intensity of the second wireless network is determined to be greater than the preset intensity threshold and the signal stability is determined to be greater than the preset stability threshold. The signal stability may be determined according to at least one of network parameters such as signal noise, retry rate, and disconnection rate, which is not limited herein.

In an embodiment of the present application, the disconnecting at least one of the plurality of wireless networks when it is determined that the operation state of the terminal device and the NAT timeout durations respectively corresponding to the plurality of wireless networks meet the preset condition may include:

under the condition that the terminal equipment is determined to operate in the foreground and the difference between the NAT timeout durations corresponding to the wireless networks is larger than a preset duration threshold, sending a notification message, wherein the notification message comprises a target wireless network which is recommended to be disconnected by a user;

and receiving the operation of disconnecting the target wireless network by the user, and disconnecting the target wireless network.

In an actual application scenario, a user uses some terminal devices for a long time, and especially a smart phone keeps the terminal devices running in the foreground for a long time every day. Based on this, in the embodiment of the present application, the power consumption of the terminal device may also be optimized according to the NAT timeout durations of the plurality of wireless networks when the terminal device operates in the foreground. In this case, after determining the wireless network that needs to be disconnected, a notification message including a target wireless network that suggests the user to disconnect may be sent to the user. The user can select to close the target wireless network according to the notification message.

In some examples, the notification message may be presented in a pop-up style. As shown in fig. 5, during the use of the instant messaging application, the terminal device 400 determines that the Wi-Fi network consumes too much power according to the solutions provided in the above embodiments, and suggests the user to turn off the Wi-Fi network. Then, a popup 401 is set in the user interface, and a corresponding notification message is presented in the popup 401. Of course, a control 403 may also be set in the pop-up window 401, and after the user performs a preset operation on the control 403, the user interface may jump to the setting interface of the wireless network shown in fig. 6, and in the setting interface, the user may close the corresponding wireless network. In other embodiments, after the user determines to disconnect the wireless network through the control, the terminal device may close the corresponding wireless network in the background to simplify the user's operation.

and under the condition that the terminal equipment is determined to operate in the foreground and the difference between the NAT timeout durations corresponding to the wireless networks is greater than a preset duration threshold, disconnecting at least one wireless network in the wireless networks and keeping the network identifier of the at least one wireless network in the opened state.

In an actual application scenario, a user senses whether a wireless network in the terminal device is started or not as a state of a network identifier of the wireless network, and the wireless network has two different states such as whether an icon exists in a menu bar, whether the icon is in different colors, whether the icon is lighted or not, and the like when the wireless network is started and disconnected. In an embodiment of the present application, in order to make a user unaware of the disconnection of the wireless network, the network identifier state of the wireless network may be set to be the network identifier state when the network identifier state of the wireless network is turned on after the wireless network is disconnected.

The disconnecting of at least one of the plurality of wireless networks according to the embodiments of the present application may include disconnecting a wireless network with a shorter NAT timeout period, or only leaving a wireless network with a longest NAT timeout period, disconnecting all remaining wireless networks, or leaving a wireless network with a longest NAT timeout period, and disconnecting at least one remaining wireless network may include a disconnection manner determined by any NAT timeout period, which is not limited herein.

The embodiment based on S105 is not limited to the above-described example, and the embodiment based on S107 is not limited to the above-described example. In an example, the disconnecting at least one of the plurality of wireless networks when it is determined that the operation state of the terminal device and the NAT timeout durations respectively corresponding to the plurality of wireless networks meet a preset condition may further include:

under the condition that the terminal equipment is determined to operate in the background, determining at least one target wireless network to be disconnected according to the NAT timeout duration;

In some embodiments, the angular velocity of the cell phone 200 about three axes (i.e., x, y, and z axes) may be determined by the gyro sensor 280A. I.e., the gyro sensor 280A may be used to detect the current state of motion of the handset 200, such as shaking or standing still.

The acceleration sensor 280B can detect the magnitude of acceleration of the cellular phone 200 in various directions (typically three axes). I.e., the gyro sensor 280A may be used to detect the current state of motion of the handset 200, such as shaking or standing still. When the display screen in the embodiment of the present application is a foldable screen, the acceleration sensor 280B may be used to detect a folding or unfolding operation acting on the display screen 294.

The proximity light sensor 280G may include, for example, a Light Emitting Diode (LED) and a light detector, such as a photodiode. The light emitting diode may be an infrared light emitting diode. The mobile phone emits infrared light outwards through the light emitting diode. The handset uses a photodiode to detect infrared reflected light from nearby objects. When sufficient reflected light is detected, it can be determined that there is an object near the handset. When insufficient reflected light is detected, the handset can determine that there are no objects near the handset. When the display screen in the embodiment of the present application is a foldable display screen, the proximity optical sensor 280G may be disposed on a first screen of the foldable display screen 294, and the proximity optical sensor 280G may detect a folding angle or an unfolding angle of the first screen and the second screen according to an optical path difference of the infrared signal.

The gyro sensor 280A (or the acceleration sensor 280B) may transmit the detected motion state information (such as an angular velocity) to the processor 210. The processor 210 determines whether the mobile phone 200 is currently in the hand-held state or the tripod state (for example, when the angular velocity is not 0, it indicates that the mobile phone 200 is in the hand-held state) based on the motion state information.

The fingerprint sensor 280H is used to collect a fingerprint. The mobile phone 200 can utilize the collected fingerprint characteristics to realize fingerprint unlocking, access to an application lock, fingerprint photographing, fingerprint incoming call answering and the like.

The demodulator is used for demodulating the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then passes the demodulated low frequency baseband signal to a baseband processor for processing. The low frequency baseband signal is processed by the baseband processor and then transferred to the application processor. The application processor outputs a sound signal through an audio device (not limited to the speaker 270A, the receiver 270B, etc.) or displays an image or video through the display screen 294.
