TECHNICAL FIELD

[0001] The present application relates to the terminal field, and in particular to a wireless connection method, an electronic device and a communication system. BACKGROUND

[0002] At present, wireless communication technologies are widely used, such as WiFi communication technology, Bluetooth communication technology and the like. Users have high quality and high stability requirements for wireless connections established by using these wireless communication technologies. How to improve the quality and stability of wireless connections is a problem to be solved. SUMMARY

[0003] The present application provides a wireless connection method, an electronic device and a communication system. Specifically, after a first device and a second device establish a wireless connection, the first device performs connection detection. If it is detected that the connection state does not meet a stable state, connection self-healing is performed by reconnection or restarting and the like. Optionally, the method further includes: after connection self-healing succeeds, connection detection and the like are continuously performed; and after connection self-healing fails, other devices are selected according to a priority order to establish a connection.

[0004] In a first aspect, the present application provides a wireless connection method. The method is applied to a first device including a wireless communication module. The method includes: establishing a first connection with a second device through the wireless communication module; detecting that the first connection does not meet a stable state; disconnecting the first connection and re-establishing a second connection with the second device through the wireless communication module; detecting that the second connection does not meet the stable state; restarting the wireless communication module and re-establishing a third connection with the second device through the wireless communication module.

[0005] After the method provided in the first aspect is implemented, the stability of the connection can be improved. Specifically, the first device can detect in advance that the connection state is unstable through connection detection, and the connection state can be restored in time through connection self-healing, thereby avoiding problems such as connection lag and disconnection caused by a long time in an unstable state, and improving the stability of the connection. In combination with the method provided in the first aspect, the condition that the connection does not meet the stable state includes: the connection is not disconnected, and a connectivity test exceeds a preset time length and / or a signal strength is less than a preset strength; and the connection includes the first connection, the second connection or the third connection.

[0006] In this way, whether the connection state is stable can be detected through multiple ways, and the accuracy of connection state detection is improved.

[0007] In combination with the method provided in the first aspect, the condition that the connection does not meet the stable state includes: the connection is not disconnected, and N times of connectivity tests exceed a preset time length and / or a signal strength is less than a preset strength, N≥1.

[0008] In this way, accidental connection instability can be excluded, and the accuracy of the connection state detection is further improved.

[0009] With reference to the method provided in the first aspect, the method further includes: detecting that the third connection does not meet the stable state; and establishing a fourth connection with a third device through the wireless communication module.

[0010] In this way, the quality of the connection can be improved. Specifically, after the connection self-recovery fails, the first device selects a corresponding device from available other devices to establish a wireless connection, thereby guaranteeing the quality of the connection of the first device.

[0011] With reference to the method provided in the first aspect, the third device is a device with the highest priority among devices connectable by the first device, and the priority of the device is determined according to any one or more of the following: a connectivity test duration, a signal strength, a transmission rate, a number of times of reestablishing a connection, a time required for reestablishing a connection, a ratio of reestablishing a connection meeting the stable state, or a user setting.

[0012] In this way, the priority of the device can be determined according to multi-dimensional detection data and user habits, thereby further guaranteeing the stability and quality of the connection established with the new device.

[0013] With reference to the method provided in the first aspect, the stable state is a first stable state, and the method further includes: updating the first stable state to a second stable state according to any one or more of the number of times of reestablishing a connection, the time required for reestablishing a connection, or the ratio of reestablishing a connection meeting the stable state.

[0014] With reference to the method provided in the first aspect, when the ratio of reestablishing a connection meeting the stable state is lower than a first preset ratio, a range of the second stable state is greater than a range of the first stable state; and when the ratio of reestablishing a connection meeting the stable state is higher than a second preset ratio, the range of the second stable state is smaller than the range of the first stable state, where the first preset ratio is smaller than the second preset ratio.

[0015] In this way, the normal communication of the first device can be avoided from being affected by excessively strict detection conditions, and the wireless connection established can also be guaranteed to have high stability and high quality, thereby improving the user experience.

[0016] With reference to the method provided in the first aspect, before detecting that the connection state of the first connection does not meet the stable state, the method further includes: receiving a first operation.

[0017] In this way, the switch can be provided to determine whether to start the connection detection, self-recovery and other functions according to the switch operation (also referred to as the first operation) of the user, so as to meet the personalized needs of the user.

[0018] With reference to the method provided in the first aspect, the first device further comprises a first application, and the first device performs the following through the first application: detecting that the first connection does not meet the stable state; disconnecting the first connection, and re-establishing the second connection with the second device through the wireless communication module; detecting that the second connection does not meet the stable state; restarting the wireless communication module, and re-establishing the third connection with the second device through the wireless communication module.

[0019] In this way, the method provided in the application can be realized by installing the first application.

[0020] With reference to the method provided in the first aspect, the first device is a terminal-side device, and the second device is a network-side device.

[0021] In this way, by improving the connection stability of the terminal-side device and the network-side device, the online experience of the terminal-side device can be improved.

[0022] With reference to the method provided in the first aspect, the wireless communication module is a wireless fidelity (Wi-Fi) module.

[0023] In this way, the WiFi service experience of the first device can be provided.

[0036] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " represents the meaning of or, for example, A / B can represent A or B; the "and / or" in the text only describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which means that there are three cases of A alone, A and B together, and B alone.

[0037] Hereinafter, the terms "first", "second", "third", etc. are used only for the purpose of description, and are not to be construed as implying or suggesting relative importance or an implied indication of the number of indicated technical features. Thus, the features defined with "first", "second" can explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0038] Reference to "an embodiment" in this application means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearance of the phrase in various places in the specification does not necessarily all refer to the same embodiment, nor is it necessarily independent or alternative embodiments to each other. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the application can be combined with other embodiments.

[0039] The term "user interface (UI)" in the following embodiments of the present application is a medium interface for interaction and information exchange between an application program or an operating system and a user, which realizes the conversion between the internal form of information and the form acceptable to the user. The user interface is source code written in a specific computer language such as Java, extensible markup language (XML), etc. The interface source code is parsed, rendered, and finally presented as content recognizable by the user on the electronic device. The commonly used form of user interface is graphic user interface (GUI), which refers to a user interface displayed in a graphical manner related to computer operation. It can be a visual interface element such as text, icon, button, menu, tab, text box, dialog box, status bar, navigation bar, Widget, etc. displayed in the display screen of the electronic device.

[0040] With the development of wireless communication technology, more and more electronic devices will use communication technologies such as WiFi, Bluetooth, etc. to establish wireless connections. However, the wireless connection established by such communication technologies is unstable and is easily affected by various factors such as environment, device hardware and software functions, etc., resulting in problems such as lag, fluctuation and disconnection of wireless connection. After the user discovers the wireless connection failure, the user needs to manually implement relevant operations to restore the wireless connection. It can be seen that during the period from the failure of the wireless connection to the restoration of the wireless connection, the time is long, which not only delays the user's online experience, but also needs to rely on manual operation to restore the wireless connection, greatly reducing the user experience.

[0041] To solve the above problems, the application provides a wireless connection method, an electronic device and a communication system. The method includes connection detection, connection self-recovery and connection optimization, and specifically includes: after the first device and the second device establish a wireless connection, the first device performs connection detection, and in the case that the connection state does not meet the stable state, connection self-recovery is performed through reconnection or through restarting and the like. Optionally, the method further includes: after the connection self-recovery is successful, the connection detection and the like are continued to be performed, and after the connection self-recovery fails, other devices are selected according to a priority order for connection. The priority is obtained by the first device based on stored connection state detection data, connection self-recovery data and the like between the first device and each device.

[0042] Further, the application provides a wireless connection method further including updating the connection detection condition, specifically including that the first device updates the detection condition, i.e., the stable state, based on the obtained connection self-recovery data. For example, when the connection self-recovery data obtained by the first device indicates that the connection self-recovery success rate is lower than a first preset ratio, the connection detection condition is relaxed; when the connection self-recovery data indicates that the connection self-recovery success rate of the first device is higher than a second preset ratio, the connection detection condition is limited, wherein the first preset ratio is smaller than the second preset ratio.

[0043] Further, the wireless connection method provided by the application can be implemented by an application / component / service installed in the electronic device, which can be provided by the system or by a third party. The system provided means that the manufacturer of the electronic device provides or develops, and the third party provided means that the manufacturer of the electronic device does not provide or develop. The manufacturer of the electronic device can include the manufacturer, supplier, provider or operator of the electronic device and the like.

[0044] Further, in an optional implementation manner, after the first device establishes a wireless connection with other devices, the method of the above connection detection, connection self-recovery and connection optimization is executed by default. In another optional implementation manner, after the first device establishes a wireless connection with other devices, whether to execute the method of the above connection detection, connection self-recovery and connection optimization is determined based on whether the corresponding function is started by the user.

[0045] The wireless connection method provided by the application can be applied to the following scenarios: the end-side device including a communication module, a communication network test production line, and the like, and the embodiments of the application do not limit the same.

[0046] Next, related concepts involved in the application are introduced:

[0047] Wireless connections, including but not limited to wireless fidelity (Wi-Fi) connections, bluetooth (BT) connections, and the like established through wireless communication technologies.

[0048] Connection detection, including but not limited to connectivity detection, signal strength detection, and the like. Connectivity can be detected, for example, through a packet internet groper (Ping). Signal strength can be detected, for example, through an ADB command, and the like.

[0049] The connection state not meeting the stable state includes that the connection is not disconnected, and the connectivity test exceeds a preset time length and / or the signal strength is less than a preset strength. The specific connection state not meeting the stable state includes that the time length obtained by N (N≥1) times of connectivity tests is greater than the preset time length, and / or the signal strength is less than the preset strength. The N times can be continuous or discontinuous. When the connection state is in the state not meeting the stable state for a long time, the connection is lagged and is prone to disconnection. Optionally, the connection state not meeting the stable state can also include a state in which the connection is disconnected.

[0050] Reconnection refers to that the first device reestablishes a connection with the current device after the first device disconnects from the current device. The reconnection usually takes a short time and does not affect the user's network communication experience, and can solve the network lag problem to a certain extent.

[0051] Restart refers to that the first device restarts the wireless communication module, for example, powers off and then powers on the wireless communication module after resetting the network factory settings, and then reestablishes a connection with the device connected before the restart. The restart can usually solve the network running failure problem of the first device, thereby solving the network lag problem.

[0052] Connection self-healing success refers to that the connection state between the first device and the device connected after the reconnection or the restart meets the stable state. Conversely, connection self-healing failure refers to that the connection state between the first device and the device connected after the reconnection or the restart still does not meet the stable state.

[0053] The connection state detection data includes but is not limited to any one or more of the following: connectivity test time length, signal strength, transmission rate, and the like corresponding to the detection object (device identifier) and the detection time.

[0054] The connection self-healing data includes but is not limited to any one or more of the following: the number of self-healings, the number of self-healing successes, the time required for self-healing success, the number of self-healings within a preset time, and the like corresponding to the self-healing object (device identifier) and the self-healing time.

[0055] The priority refers to a priority of the first device based on any one or more of the stored connection state detection data between devices, the connection self-recovery data, and the user's frequently connected device preferences. The higher the priority, the more stable the connection established with the device, and the more in line with the user's expectations. The lower the priority, the more volatile the connection established with the device, and the less in line with the user's expectations.

[0056] It can be seen that after the wireless connection method, the electronic device, and the communication system provided by the present application are implemented, the following beneficial effects can be brought about:

[0057] (1) Improving the stability of the connection. Specifically, the first device can detect the unstable connection state in advance through connection detection, and restore the connection state in time through connection self-recovery, thereby avoiding the problems of connection lag and disconnection caused by a long time in an unstable state, and improving the stability of the connection.

[0058] (2) Improving the quality of the connection. Specifically, after the connection self-recovery fails, the first device selects a corresponding device to establish a wireless connection from the available other devices, thereby ensuring the quality of the connection of the first device.

[0059] (3) Reducing the workload of manual operation and maintenance of the connection. Specifically, the connection detection, the connection self-recovery, and the connection optimization are all fully automated, and do not require human intervention for connection detection, connection maintenance, and connection selection. In this way, when the first device performs an online service, the user does not need to constantly monitor the connection state, and the normal execution of the online service can still be ensured.

[0060] Next, the device and the communication system to which the wireless connection method provided by the present application is applied are introduced.

[0061] Figure 1 An example of a communication system 10 involved in a production line test scenario is shown.

[0062] As shown in Figure 1 , the communication system 10 includes a wireless access point and a plurality of node devices. The wireless access point and the plurality of node devices are each provided with a wireless communication module, and the plurality of node devices can establish a wireless connection with the wireless access point through the wireless communication module. The wireless communication module includes a wireless local area network (WLAN), and when the wireless connection is a Wi-Fi connection, the node device can also be referred to as an end-side device, and the wireless access point can also be referred to as a network-side device.

[0063] Optionally, the communication system 10 can further include more wireless access points and node devices, etc., and the embodiments of the present application do not limit this.

[0064] In this communication system 10, multiple node devices connected to the wireless access point can be used by testers to test the wireless communication functions of the node devices. During the testing of the node devices after the wireless access device and node devices have established a connection, if a connection failure occurs and the connection is lost, it will affect the testing of the node devices. However, by using the wireless connection method provided in this application, connection stability can be ensured through connection detection and connection self-healing, thereby reducing the workload of testers on the production line and improving the testing efficiency of the node devices.

[0065] In production line testing scenarios, connectivity detection and connectivity self-healing can be performed by wireless access point devices or by node devices, and this application embodiment does not limit this.

[0066] Figure 2 An example of a communication system 10 involved in a product application scenario is shown.

[0067] like Figure 2 As shown, the communication system 20 includes: node devices and multiple wireless access points. Both the node devices and the multiple wireless access points are equipped with wireless communication modules, through which the node devices can establish wireless connections with the wireless access points. The wireless communication modules include Wireless Local Area Networks (WLANs). When the wireless connection is specifically a Wi-Fi connection, the node devices can also be referred to as end-side devices, and the wireless access points can also be referred to as network-side devices.

[0068] Optionally, the communication system 20 may also include more wireless access points and node devices, etc., and this application embodiment does not limit this.

[0069] In this communication system 20, the node device can select the optimal wireless access point to establish a connection for communication with the wireless access point and for performing internet access services. After the node device establishes a connection with the wireless access device 1, if a connection failure occurs and the connection is lost, it will affect the node device's internet access services. However, by using the wireless connection method provided in this application, connection stability can be ensured through connection detection, connection self-healing, and connection optimization, thereby improving the user's experience of using the node device to access the internet.

[0070] In product application scenarios, connectivity detection and connectivity self-healing can be performed by the product and node devices.

[0071] Based on the foregoing description of the application scenarios of wireless communication system 10 and communication system 20, it can be understood that the device forms of the aforementioned node devices and wireless access points can be as follows.

[0072] Node devices may include, but are not limited to: carrying Or other portable terminal devices with different operating systems, such as mobile phones, tablets, desktop computers, laptops, handheld computers, laptops, ultra-mobile personal computers (UMPCs), netbooks, as well as cellular phones, personal digital assistants (PDAs), augmented reality (AR) devices, virtual reality (VR) devices, artificial intelligence (AI) devices, wearable devices, in-vehicle devices, smart home devices and / or smart city devices, etc.

[0073] Wireless access points can include, but are not limited to: routers, devices equipped with... Or portable terminal devices with other operating systems, such as mobile phones, tablets, etc.

[0074] Next, combined Figure 3 The wireless connection method provided in this application will be described in detail using a product application scenario as an example. The implementation of this wireless connection method in production line testing scenarios is similar to the following description, and will not be repeated here.

[0075] refer to Figure 3 , Figure 3 An example is shown of a wireless connection method provided in this application.

[0076] like Figure 3 As shown, the method includes the following steps. The first device involved in the method is the node device in the aforementioned communication system 20, and the second and third devices involved in the method are wireless access point 1, wireless access point 2, etc. in the aforementioned communication system 20.

[0077] S31, the first device establishes a connection with the second device.

[0078] Specifically, based on user operation, the first device can establish a connection with the second device via wireless communication technology. Alternatively, without user operation, if the electronic device has its wireless communication function enabled and the communication distance between the first and second devices meets the requirements, the first device can also automatically connect to the second device via wireless communication technology. In the embodiments of this application, the connection established between the first device and the second device in S31 can also be referred to as the first connection.

[0079] The user operation triggering the first device to connect to the second device includes, but is not limited to, an operation on a second device option, an operation of scanning a label of the second device, an operation of inputting, for example, an ADB command to the first device, and the like. Embodiments of the present application do not limit the scenario of triggering the first device to connect to the second device.

[0080] The wireless communication technology includes, but is not limited to, any one or more of the following: Wi-Fi, BT, NFC, and the like.

[0081] The connection includes, but is not limited to, a Wi-Fi connection, a BT connection, and the like. Hereinafter, a Wi-Fi connection is exemplarily introduced, and embodiments of the present application do not limit the connection.

[0082] S32, the first device detects whether the connection state between the first device and the second device meets a stable state.

[0083] Specifically, the first device can periodically (i.e., periodically polling) detect whether the connection state between the first device and the second device meets the stable state.

[0084] When it is detected that the connection state between the first device and the second device does not meet the stable state, the first device executes subsequent S33-S37. When it is detected that the connection state between the first device and the second device meets the stable state, the first device does not execute subsequent S33-S37, and continues to execute S32, i.e., polling to detect the connection state.

[0085] The detection method includes detecting connectivity by Ping and detecting signal strength by an ADB command, and the like. Embodiments of the present application do not limit the specific command used for the connectivity test and the signal strength test. In different platforms, the command used can be different.

[0086] The stable state can be stored in a connection detection module of the first device. Specifically, the state that does not meet the stable state includes that a time length obtained by performing connectivity test for N (N≥1) times continuously is greater than a preset time length, and / or the signal strength is less than a preset strength. The state that meets the stable state includes that the time length obtained by performing the connectivity test is less than or equal to the preset time length, and / or the signal strength is greater than or equal to the preset strength. The preset time length can be, for example, 100 ms, and the preset strength can be, for example, -75 dbm. Embodiments of the present application do not limit the specific values.

[0087] Optionally, the first device automatically performs the connection state detection in S32 after establishing the connection with the other device, and then detects the unstable connection state in time to perform the subsequent connection self-recovery and connection optimization. Alternatively, the first device performs the connection state detection in S32 after establishing the connection with the other device, and determines whether to start the corresponding function, and only when it is determined to start the corresponding function, the connection state detection in S32 is performed. The corresponding function is specifically provided by an application / component / service installed in the electronic device.

[0088] S33, the first device re-establishes the connection with the second device.

[0089] Specifically, after the first device detects that the connection state with the second device does not meet the stable state, the first device performs connection self-recovery, which includes preliminary self-recovery and further self-recovery. The preliminary self-recovery includes re-establishing the connection, and the further self-recovery includes restarting and then re-establishing the connection. The further self-recovery is performed when the connection state still does not meet the stable state after the preliminary self-recovery. Therefore, in S33, the first device specifically performs the preliminary self-recovery, that is, disconnects the connection with the second device, and then re-establishes the connection with the second device.

[0090] In the embodiments of the present application, the connection re-established by the first device and the second device in S33 can also be referred to as a second connection.

[0091] S34, the first device detects whether the connection state between the first device and the second device meets the stable state.

[0092] Specifically, S34 is similar to the execution method of the foregoing S32, and the difference is that the connection detected in S32 is the connection established between the first device and the second device before self-recovery, and the connection detected in S34 is the connection established between the first device and the second device after the preliminary self-recovery.

[0093] When it is detected that the connection state after reconnection with the second device does not meet the stable state, the first device performs the subsequent S35-S37, and when it is detected that the connection state after reconnection with the second device meets the stable state, the first device does not perform the subsequent S35-S37, but jumps to continue to perform S32, that is, polls the connection state.

[0094] S35, the first device re-establishes the connection with the second device after restarting the wireless communication module.

[0095] Specifically, after the first device detects that the connection state after reconnection with the second device does not meet the stable state, the first device performs further self-recovery, that is, restarts the wireless communication module of the first device, for example, powers off and then powers on the wireless communication module after resetting the network factory settings, and then re-establishes the connection with the device connected before the restart.

[0096] In the embodiments of the present application, the connection re-established by the first device after restarting the wireless communication module and the second device in S35 can also be referred to as a third connection.

[0097] S36, the first device detects whether the connection state between the first device and the second device meets the stable state.

[0098] Specifically, S36 is similar to the execution methods of the aforementioned S32 and S34. The difference among the three is that: the connection detected in S32 is the connection established by the first device and the second device before the preliminary self-healing, or after the preliminary self-healing and the successful self-healing, or after the further self-healing and the successful self-healing; the connection detected in S34 is the connection established by the first device and the second device after the reconnection before the further self-healing; and the connection detected in S36 is the connection established by the first device and the second device after the reconnection after the further self-healing.

[0099] When it is detected that the connection state of the first device and the second device after the restart does not meet the stable state, the first device executes the subsequent S37; when it is detected that the connection state of the first device and the second device after the restart meets the stable state, the first device does not execute the subsequent S37, but jumps to continue to execute S32, i.e., polling the detection of the connection state.

[0100] S37, the first device establishes a connection with a third device having the highest priority.

[0101] Specifically, after the self-healing of the connection between the first device and the second device fails, the first device selects a third device having the highest priority from the other connectable devices to establish a connection.

[0102] The priority is obtained by the following method: after the first device establishes a connection with each device, the first device records the connection state detection data and the connection self-healing data during the execution of the connection state detection and the connection self-healing processes described in the aforementioned S32-S36, or the first device also records the user's preference for frequently connected devices, and based on any one or more of these data, the first device prioritizes the connected devices, and periodically updates the priority based on the updated data.

[0103] In the embodiments of the present application, the connection established by the first device and the third device having the highest priority in S37 can also be referred to as a fourth connection.

[0104] Optionally, after the first device establishes a connection with the third device, the first device continues to perform the connection state detection, the connection self-healing, and the connection optimization of the third device, and the specific description can be referred to the aforementioned S36-S37, which will not be described here.

[0105] The steps S36-S37 above are optional. That is, the wireless connection method provided in this application may only include the connection detection and connection self-healing stages, or the wireless connection method provided in this application may include the connection detection, connection self-healing and connection optimization stages.

[0106] Regarding the method for the first device to perform the connection optimization described in S37 above, please refer to the following text for details. Figure 4 The description.

[0107] Figure 4 An exemplary embodiment illustrates a connection optimization method involved in the wireless connection method provided in this application.

[0108] like Figure 4 As shown, the method includes the following steps:

[0109] S41, the first device stores information about the devices with established connections.

[0110] Specifically, during the process of establishing a connection with the peer device, the first device will obtain information about the peer device, including but not limited to: device identifier, protocol type, and connection mode.

[0111] The peer devices include, but are not limited to, the second and third devices mentioned above. Device identification includes, for example, device name and network address. Protocol types include, but are not limited to, IEEE 802.11a, 802.11b, 802.11n, 802.11ac, 802.11ax, and some other self-developed protocols. Connection modes include automatic connection and manual connection. Automatic connection means that when the first device detects that the connection conditions are met, the first device can directly connect to the device without manual user intervention. Manual connection means that a connection can only be established with the device after user input.

[0112] S42, The first device stores connection status detection data with the connected devices.

[0113] Specifically, after establishing a connection with the peer device, the first device will perform connection status detection as described in S32, S34 and S36 above. Therefore, the first device will also store connection status detection data, which includes, but is not limited to, any one or more of the following: the detection object (device identifier) ​​and the detection time, the connectivity test duration, signal strength, transmission rate, etc.

[0114] S43, the first device stores connection self-healing data with connected devices.

[0115] Specifically, after the first device detects the connection state of the established connection, if the connection state does not conform to the stable state, the first device performs the connection self-recovery as described in S33 and S35. Therefore, the first device also stores connection self-recovery data, which includes but is not limited to any one or more of the following: the number of self-recoveries, the number of successful self-recoveries, the time required for a successful self-recovery, the number of self-recoveries within a preset time, and the like corresponding to the self-recovery object (device identifier) and the self-recovery time.

[0116] S44, the first device obtains the user's preference for the frequently connected device.

[0117] Specifically, the first device can calculate the connection frequency of the connected devices, and if a device is connected more frequently, it is determined that the user prefers to connect the device. Alternatively, the first device can also provide a setting item for the frequently connected device, and then based on the user's setting operation, the user's setting for the frequently connected device is regarded as the device that the user prefers to connect.

[0118] In the embodiments of the present application, S44 is an optional operation.

[0119] In the embodiments of the present application, the order of S41-S44 performed by the first device is not limited, and the first device can perform S41-S44 simultaneously or in any other order, which is not limited in the embodiments of the present application.

[0120] S45, the first device determines the priority of each device based on any one or more of the connection state detection data, the connection self-recovery data, or the user's preference for the frequently connected device.

[0121] Specifically, the first device can periodically determine the priority of each device based on any one or more of the latest stored connection state detection data, connection self-recovery data, and user's preference for the frequently connected device. The higher the priority of a device, the more stable the connection established between the first device and the device, and the more in line with the user's expectations; the lower the priority, the more likely the connection established between the first device and the device to fluctuate, and the less in line with the user's expectations.

[0122] When the first device determines the priority based on the connection state detection data, the connection self-recovery data, and the user's preference for the frequently connected device, the priority can be determined according to the following order from high to low according to the importance of the factors: the signal strength of the connection, the user's preference, the number of self-recoveries and the time required for a successful self-recovery, and the number of self-recoveries within a preset time (i.e., the number of times the connection state does not conform to the stable state within a preset time).

[0123] Next, the software and hardware architecture of the electronic device related in the present application is introduced.

[0124] The software system of the first device can adopt a layered architecture, event-driven architecture, microkernel architecture, microservice architecture, or cloud architecture. This application embodiment uses a layered architecture. Taking the system as an example, the software structure of the first device is illustrated.

[0125] Figure 5 This is a schematic diagram of the software architecture of the first device according to an embodiment of this application.

[0126] A layered architecture divides software into several layers, each with a clear role and function. Layers communicate with each other through software interfaces. In some embodiments, [the following is omitted as the text is incomplete and likely refers to a specific implementation or feature]. The system is divided into four layers, from top to bottom: the application layer, the application framework layer, the Android runtime layer, and the application application framework layer. runtime and system libraries, as well as the kernel layer.

[0127] The application layer can include a series of application packages.

[0128] like Figure 5 As shown, the application package may include a wireless connectivity application (also referred to as the first application), and Figure 5 Automated testing, not shown, is used for applications such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, and SMS.

[0129] The name of the wireless connection application is merely an example. It is mainly used to provide a solution for the wireless connection method described in this application, including establishing a connection, detecting the connection status, connection self-healing, connection optimization, and updating detection conditions, etc.

[0130] Wireless connectivity applications include, but are not limited to, the following modules: connectivity module, encoding protocol, detection module, self-healing module, optimization module, and update module, etc.

[0131] The connection module is mainly used to obtain device information and parse the device information according to the encoding protocol, and establish a wireless connection with the device based on the parsed device information according to the encoding protocol used.

[0132] The encoding protocol is mainly used to store supported protocols, including but not limited to self-developed protocols and standard protocols such as IEEE 802.11a, 802.11b, 802.11n, 802.11ac, 802.11ax, etc. This self-developed protocol is mainly used by electronic device 100 to establish wireless connections with other devices to achieve wireless functionality.

[0133] The detection module is mainly used for detecting the connection state after the connection module successfully establishes a connection with the opposite device, such as the electronic device 200, including but not limited to detecting connectivity, signal strength, etc. through a Ping command. In addition, the detection module is also used to store the detected connection state data for the optimization module to prioritize the connectable devices.

[0134] The self-healing module is mainly used for connection self-healing after detecting that the connection state does not meet the stable state, including preliminary self-healing and reconnection through self-healing stage 1, and further self-healing through self-healing stage 2 after the preliminary self-healing fails, that is, controlling the wireless connection module to power off and then power on to establish a connection again. In addition, the self-healing module is also used to store the self-healing data for the optimization module to prioritize the connectable devices.

[0135] The optimization module is mainly used for prioritizing the multiple connectable devices, and selecting the highest priority device from the connectable devices to establish a connection after the further self-healing of the self-healing module fails.

[0136] The update module is mainly used for updating the detection conditions of the connection module according to the self-healing detection data, for example, when the connection self-healing data obtained by the first device indicates that the connection self-healing success rate is lower than a first preset ratio, the connection detection conditions are relaxed, for example, the preset time length of the connectivity test is lengthened, and / or the signal strength less than the preset strength is reduced, that is, the stable state is modified from the original first stable state to a second stable state. The range of the second stable state is greater than the range of the first stable state, so that the normal communication of the electronic device 100 can be avoided due to too strict detection conditions; when the connection self-healing data indicates that the connection self-healing success rate of the first device is higher than a second preset ratio, the connection detection conditions are limited, for example, the preset time length of the connectivity test is reduced, and / or the signal strength less than the preset strength is increased, that is, the stable state is modified from the original first stable state to a second stable state. The range of the second stable state is less than the range of the first stable state. The first preset ratio is less than the second preset ratio, so that the wireless connection established can have high stability and high quality, and the user experience can be improved.

[0137] The automatic test is usually used in the production line of the electronic device 100, and the automatic test is not provided at the user end after the product goes online, so it is not expanded here.

[0147] The notification manager makes the application program display the notification information in the status bar, which can be used to convey the message of the notification type, which can automatically disappear after a short stay without user interaction. For example, the notification manager is used to notify the download completion, message reminder, etc. The notification manager can also be the notification in the form of chart or scrolling text in the top status bar of the system, such as the notification of the application program running in the background, and can also be the notification in the form of dialogue window appearing on the screen. For example, the text information is prompted in the status bar, the prompt sound is emitted, the first device vibrates, the indicator light flashes, etc.

[0148] The Android runtime includes the core library and the virtual machine. The Android runtime is responsible for the scheduling and management of the Android system.

The pressure sensor 180A can be of various types, such as a resistive pressure sensor, an inductive pressure sensor, a capacitive pressure sensor, etc. The capacitive pressure sensor can include at least two parallel plates of conductive material. When a force is applied to the pressure sensor 180A, the capacitance between the electrodes changes. The electronic device 100 determines the intensity of the pressure according to the change in capacitance. When a touch operation is applied to the display screen 194, the electronic device 100 detects the intensity of the touch operation according to the pressure sensor 180A. The electronic device 100 can also calculate the position of the touch according to the detection signal of the pressure sensor 180A. In some embodiments, touch operations applied to the same touch position but with different touch operation intensities can correspond to different operation instructions. For example, when a touch operation with a touch operation intensity less than a first pressure threshold is applied to a short message application icon, an instruction to view short messages is executed. When a touch operation with a touch operation intensity greater than or equal to the first pressure threshold is applied to the short message application icon, an instruction to create a new short message is executed.

The touch sensor 180B is configured to detect a touch operation applied thereto or in the vicinity thereof. The touch sensor 180B can transmit the detected touch operation to the application processor to determine the type of touch event. Visual output related to the touch operation can be provided through the display screen 194. In other embodiments, the touch sensor 180B can also be disposed on the surface of the electronic device 100, which is different from the position of the display screen 194.
