[0002] Currently, wireless communication technologies are widely used, such as WiFi communication technology, Bluetooth communication technology, etc. Users have high quality and high stability requirements for wireless connections established using these wireless communication technologies. How to improve the quality and stability of wireless connections is an urgent problem to be solved. Summary of the invention

[0003] The present application provides a wireless connection method, electronic device and communication system. Specifically, it includes: after the first device establishes a wireless connection with the second device, the first device performs a connection detection, and when it is detected that the connection state does not meet the stable state, the connection self-healing is performed by reconnecting or restarting. Optionally, the method also includes: after the connection self-healing is successful, the connection detection is continued, and after the connection self-healing fails, other devices are selected for connection according to the priority order.

[0004] In a first aspect, the present application provides a wireless connection method, which is applied to a first device including a wireless communication module, and the method includes: establishing a first connection with a second device through the wireless communication module; detecting that the first connection does not conform to 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 conform to 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 implementing the method provided in the first aspect, the stability of the connection can be improved. Specifically, the first device can detect in advance the situation of unstable connection state through connection detection, and can restore the connection state in time through connection self-healing, avoiding the problem of connection jamming and connection disconnection caused by being in an unstable state for a long time, thereby improving the stability of the connection. In combination with the method provided in the first aspect, not meeting the stable state includes: the connection is not disconnected, and the connectivity test exceeds the preset time and / or the signal strength is less than the preset strength; the connection includes the first connection, the second connection or the third connection.

[0006] In this way, whether the connection status is stable can be detected in multiple ways, thereby improving the accuracy of connection status detection.

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

[0008] In this way, occasional connection instability can be eliminated and the accuracy of connection status detection can be further improved.

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

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

[0011] In combination with the method provided in the first aspect, the third device is the device with the highest priority among the devices that the first device can connect to, and the priority of the device is determined based on any one or more of the following: the connectivity test duration, signal strength, transmission rate of the first device's historical connection devices, the number of times the connection is re-established, the time required to re-establish the connection, the ratio of the re-established connection to the stable state, or user settings.

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

[0013] In combination with the method provided in the first aspect, the stable state is a first stable state, and the method also includes: updating the first stable state to a second stable state based on any one or more of the number of times the first device re-establishes the connection, the time required to re-establish the connection, or the ratio of re-establishing the connection that meets the stable state.

[0014] In combination with the method provided in the first aspect, when the ratio of re-establishing the connection to comply with the stable state is lower than a first preset ratio, the range of the second stable state is greater than the range of the first stable state; when the ratio of re-establishing the connection to comply with the stable state is higher than a second preset ratio, the range of the second stable state is less than the range of the first stable state, wherein the first preset ratio is less than the second preset ratio.

[0015] In this way, it is possible to avoid detection conditions being too stringent to affect normal communication of the first device, and to avoid detection conditions being too loose, thereby ensuring that the established wireless connection has high stability and quality, thereby improving user experience.

[0016] In combination with the method provided in the first aspect, before detecting that the connection state of the first connection does not conform to the stable state, the method further includes: receiving a first operation.

[0017] In this way, a switch can be provided to determine whether to enable functions such as connection detection and self-healing according to the user's switch operation (also called the first operation) to meet the user's personalized needs.

[0036] The technical solutions in the embodiments of the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in the text is only a description of the association relationship of the associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0037] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

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

[0039] The term "user interface (UI)" in the following embodiments of the present application refers to a medium interface for interaction and information exchange between an application or 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 a source code written in a specific computer language such as Java and extensible markup language (XML). The interface source code is parsed and rendered on an electronic device, and finally presented as content that can be recognized by the user. The commonly used form of user interface is a graphical user interface (GUI), which refers to a user interface related to computer operation displayed in a graphical manner. It can be a visual interface element such as text, icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, widgets, etc. displayed on the display screen of an electronic device.

[0040] With the development of wireless communication technology, more and more electronic devices will use communication technologies such as WiFi and Bluetooth to establish wireless connections. However, the wireless connection established by this type of communication technology is unstable and easily affected by various factors such as the environment, device hardware and software functions, resulting in problems such as freezes, fluctuations, and disconnections in the wireless connection. After the user discovers a wireless connection failure, the user needs to manually perform relevant operations to restore the wireless connection. It can be seen that it takes a long time from the occurrence of a wireless connection failure to the restoration of the wireless connection, which not only delays the user's Internet experience, but also requires manual operation and maintenance to restore the wireless connection, greatly reducing the user experience.

[0041] In order to solve the above problems, the present application provides a wireless connection method, an electronic device and a communication system. The method includes connection detection, connection self-healing and connection optimization, etc., specifically including: after the first device establishes a wireless connection with the second device, the first device performs connection detection, and when it is detected that the connection state does not conform to the stable state, the connection self-healing is performed by reconnecting or restarting. Optionally, the method also includes: after the connection self-healing is successful, continue to perform connection detection, etc., and after the connection self-healing fails, select other devices for connection in order of priority. Among them, the priority is obtained by the first device sorting each device based on the stored connection status detection data, connection self-healing data, etc. with each device.

[0042] Furthermore, the present application provides a wireless connection method that also includes updating connection detection conditions, specifically including that the first device adopts the detection conditions when updating the connection detection based on the acquired connection self-healing data, that is, updating the stable state. For example, when the connection self-healing data acquired by the first device indicates that the connection self-healing success rate is lower than the first preset ratio, the connection detection conditions are relaxed; when the connection self-healing data indicates that the connection self-healing success rate of the first device is higher than the second preset ratio, the connection detection conditions are narrowed, wherein the first preset ratio is less than the second preset ratio.

[0043] Furthermore, the wireless connection method provided by the present application can be implemented by an application / component / service installed in an electronic device, and the application / component / service can be provided by the system or by a third party. Among them, system provision refers to that provided or developed by the manufacturer of the electronic device, and third-party provision refers to that provided or developed by the manufacturer of non-electronic equipment. The manufacturer of the electronic device may include the manufacturer, supplier, provider or operator of the electronic device, etc.

[0044] Further, in an optional implementation, after the first device establishes a wireless connection with other devices, the above-mentioned connection detection, connection self-healing and connection optimization methods are performed by default. In another optional implementation, after the first device establishes a wireless connection with other devices, it determines whether to perform the above-mentioned connection detection, connection self-healing and connection optimization methods based on whether the user turns on the corresponding function.

[0045] The wireless connection method provided in the present application can be applied to the following scenarios: in a terminal device including a communication module, in a communication network test production line, and the embodiments of the present application are not limited to this.

[0046] Next, we introduce the relevant concepts involved in this application:

[0047] Wireless connection includes but is not limited to wireless fidelity (Wi-Fi) connection established through wireless communication technology, Bluetooth (BT) connection, etc.

[0048] Connection detection includes but is not limited to connectivity detection, signal strength detection, etc. For example, connectivity is detected by using a packet internet groper (Ping), signal strength is detected by using an ADB command, etc.

[0049] The connection state not meeting the stable state includes: the connection is not disconnected, and the connectivity test exceeds the preset duration and / or the signal strength is less than the preset strength. The specific connection state not meeting the stable state includes: the duration obtained by performing the connectivity test N times (N≥1) is greater than the preset duration, and / or the signal strength is less than the preset strength, and the N times can be continuous or discontinuous. When the connection state is in a state that does not meet the stable state for a long time, the connection is stuck and easily disconnected. Optionally, the connection state not meeting the stable state may also include a disconnected state.

[0050] Reconnection means that the first device disconnects from the current device and then reconnects to the current device. Usually, reconnection takes a short time, does not affect the user's network communication experience, and can solve the problem of network lag to a certain extent.

[0051] Restarting means that the first device restarts the wireless communication module, for example, by restoring the network factory settings (reset) to power off and then power on the wireless communication module, and then reconnecting with the device connected before the restart. Usually, restarting can solve the problem of network operation failure of the first device, thereby solving the problem of network lag.

[0052] The connection self-healing success means that the connection state between the first device and the device connected after reconnection or restart is in a stable state. On the contrary, the connection self-healing failure means that the connection state between the first device and the device connected after reconnection or restart is still not in a stable state.

[0053] The connection status detection data includes, but is not limited to, any one or more of the following: the duration of the connectivity test, signal strength, transmission rate, etc. corresponding to the detection object (device identification) 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 successful self-healings, the time required for successful self-healing, the number of self-healings within a preset time, etc. corresponding to the self-healing object (device identifier) ​​and the self-healing time.

[0055] Priority refers to the ranking of the first device based on the stored connection status detection data with each device, connection self-healing data, and any one or more factors in the user's frequently connected device preferences. The higher the priority of the device, the more stable the connection established with the device and the more in line with user expectations; the lower the priority, the more likely the connection established with the device is to fluctuate and less in line with user expectations.

[0056] It can be seen that after implementing the wireless connection method, electronic device and communication system provided by the present application, 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 can restore the connection state in time through connection self-healing, avoiding the problem of connection jamming and disconnection caused by being in an unstable state for a long time, thereby improving the stability of the connection.

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

[0059] (3) Reduce the workload of manual operation and maintenance of connections. Specifically, connection detection, connection self-healing, and connection optimization are all fully automated, without the need for manual connection detection, connection maintenance, connection selection, and other operations. In this way, when the first device performs Internet access services, the user does not need to pay attention to the connection status at all times, and the normal execution of Internet access services can still be guaranteed.

[0060] Next, the device and communication system used by the wireless connection method provided by this application are introduced.

[0061] Figure 1 The communication system 10 involved in a production line test scenario is exemplarily shown.

[0062] like Figure 1 As shown, the communication system 10 includes: a wireless access point and multiple node devices. The wireless access point and the multiple node devices are both provided with a wireless communication module, and the multiple 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). When the wireless connection is specifically a Wi-Fi connection, the node device can also be called a terminal side device, and the wireless access point can also be called a network side device.

[0063] Optionally, the communication system 10 may also include more wireless access points and node devices, etc., which is not limited in the embodiment of the present application.

[0064] In the communication system 10, multiple node devices connected to the wireless access point can be used by testers to test the wireless communication functions in the node devices. In the process of testing the node device after the wireless access device establishes a connection with the node device, if a connection failure occurs and causes a disconnection, it will affect the test of the node device. However, after adopting the wireless connection method provided by the present application, the connection stability can be guaranteed through connection detection and connection self-healing, thereby reducing the workload of testers in the production line and improving the test efficiency of the node device.

[0065] In the production line test scenario, connection detection and connection self-healing can be specifically performed by a wireless access point device, or can also be performed by a node device, and the embodiments of the present application are not limited to this.

[0066] Figure 2 The communication system 10 involved in a product application scenario is exemplarily shown.

[0067] like Figure 2 As shown, the communication system 20 includes: a node device and multiple wireless access points. The node device and the multiple wireless access points are both provided with a wireless communication module, and the node device 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). When the wireless connection is specifically a Wi-Fi connection, the node device can also be called a terminal side device, and the wireless access point can also be called a network side device.

[0068] Optionally, the communication system 20 may also include more wireless access points and node devices, etc., which is not limited in the embodiment of the present application.

[0069] In the communication system 20, the node device can select the best wireless access point to establish a connection, so that the node device can communicate with the wireless access point and perform Internet access services, etc. After the node device establishes a connection with the wireless access device 1, if a connection failure occurs and causes disconnection, the Internet access service of the node device will be affected. However, after adopting the wireless connection method provided by the present application, the 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 surf the Internet.

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

[0071] Based on the above introduction to the application scenarios of the wireless communication system 10 and the communication system 20, it can be known that the device forms of the above node devices and wireless access points can be as follows.

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

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

[0074] Next, combine Figure 3 The wireless connection method provided by the present application is described in detail by taking the product application scenario as an example. The implementation of the wireless connection method in the production line test scenario is similar to the following description, and can be referred to the description below, which will not be repeated here.

[0075] refer to Figure 3 , Figure 3 A wireless connection method provided by the present application is exemplified.

[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. The second device and the third device involved in the method are the wireless access point 1, the 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 may establish a connection with the second device through wireless communication technology. Alternatively, without user operation, when the wireless communication function of the electronic device is turned on and the communication distance between the first device and the second device meets the conditions, the first device may also automatically connect to the second device through wireless communication technology. In the embodiment of the present application, the connection established between the first device and the second device described in S31 may also be referred to as the first connection.

[0079] The above-mentioned user operations that trigger the first device to connect to the second device include but are not limited to: operations acting on the options of the second device, operations scanning the labels of the second device, operations by inputting, for example, ADB commands to the first device, etc. The embodiments of the present application do not limit the scenarios that trigger the first device to connect to the second device.

[0080] The above wireless communication technologies include but are not limited to any one or more of the following: Wi-Fi, BT or NFC, etc.

[0081] The above connection includes but is not limited to: Wi-Fi connection, BT connection, etc., and the following text only uses Wi-Fi connection as an example, and the embodiments of the present application are not limited to this.

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

[0083] Specifically, the first device may periodically (ie, periodically poll) detect whether the connection status with the second device complies with the stable status.

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

[0085] The above detection method includes: detecting connectivity through Ping, detecting signal strength through ADB commands, etc. The embodiment of the present application does not limit the specific commands used for connectivity testing or signal strength testing, and the commands used in different platforms may be different.

[0086] The above-mentioned stable state can be stored in the connection detection module of the first device. Specifically, not meeting the stable state includes: the duration obtained by performing connectivity tests for N consecutive times (N≥1) is greater than the preset duration, and / or the signal strength is less than the preset strength. Meeting the stable state includes: the connectivity test duration is less than or equal to the preset duration, and / or the signal strength is greater than or equal to the preset strength. The preset duration can be, for example, 100ms, and the preset strength can be, for example, -75dbm. The embodiments of the present application do not limit the specific values.

[0087] Optionally, after the first device establishes a connection with other devices, it automatically performs the connection status detection described in S32, and then promptly detects the unstable connection state and performs subsequent connection self-healing and connection optimization. Alternatively, after the first device establishes a connection with other devices, it determines whether to enable the corresponding function, and only performs the connection status detection described in S32 if it is determined that the corresponding function is enabled. The corresponding function is specifically provided by the application / component / service installed in the electronic device.

[0088] S33: The first device re-establishes a connection with the second device.

[0089] Specifically, after the first device detects that the connection state with the second device does not conform to the stable state, the first device performs connection self-healing, and the connection self-healing includes preliminary self-healing and further self-healing. Among them, preliminary self-healing includes re-establishing the connection, and further self-healing includes re-establishing the connection after restarting. Further self-healing is performed when the connection state still does not conform to the stable state after the preliminary self-healing. Therefore, in S33, the first device specifically performs preliminary self-healing, that is, first disconnecting the connection with the second device, and then re-establishing the connection with the second device.

[0090] In the embodiment of the present application, the connection re-established between the first device and the second device described in S33 may also be referred to as a second connection.

[0091] S34, the first device detects whether the connection status between the first device and the second device is in a stable state.

[0092] Specifically, S34 is similar to the execution method of the aforementioned S32, except that the connection detected in S32 is the connection established between the first device and the second device before self-healing, while the connection detected in S34 is the connection established after the first device and the second device are reconnected after initial self-healing.

[0093] When it is detected that the connection status after reconnection with the second device does not conform to the stable state, the first device executes subsequent S35-S37. When it is detected that the connection status after reconnection with the second device conforms to the stable state, the first device does not execute subsequent S35-S37, but jumps to continue executing S32, that is, polling to detect the connection status.

[0094] S35, after the first device restarts the wireless communication module, it establishes a connection with the second device.

[0095] Specifically, after the first device detects that the connection state after reconnection with the second device does not conform to a stable state, the first device performs further self-healing, that is, restarting the wireless communication module of the first device, for example, by restoring the network factory settings (reset) so that the wireless communication module is powered off and then powered on, and then re-establishing a connection with the device connected before the restart.

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

[0097] S36, the first device detects whether the connection status between the first device and the second device is in a stable state.

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

[0099] When it is detected that the connection status with the second device after restart does not conform to the stable state, the first device executes the subsequent S37. When it is detected that the connection status with the second device after restart conforms to the stable state, the first device does not execute the subsequent S37, but jumps to continue executing S32, that is, polling to detect the connection status.

[0100] S37: The first device establishes a connection with the third device with the highest priority.

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

[0102] The above-mentioned priority is obtained in the following manner: after the first device establishes a connection with each device, while executing the connection status detection and connection self-healing process described in, for example, S32-S36 above, the first device will record the connection status detection data, the connection self-healing data, or the first device will also record the user's frequently connected device preferences. Based on any one or more of these data, the first device will prioritize the connected devices and regularly update the priorities based on the updated data.

[0103] In the embodiment of the present application, the connection established between the first device and the third device with the highest priority described in S37 can also be called the fourth connection.

[0104] Optionally, after establishing a connection with the third device, the first device continues to perform connection status detection, connection self-healing and connection optimization with the third device, etc. For details, please refer to the description of S36-S37 above, which will not be repeated here.

[0105] The above S36-S37 are optional steps, that is, the wireless connection method provided in the present application may only include connection detection and connection self-healing stages, or the wireless connection method provided in the present application may include 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, please refer to the following description for details. Figure 4 Description.

[0107] Figure 4 The connection optimization method involved in the wireless connection method provided in the present application is exemplified.

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

[0109] S41: The first device stores information of the device with which the connection has been established.

[0110] Specifically, in the process of establishing a connection with the opposite device, the first device may obtain information of the opposite device, including but not limited to: device identification, protocol type, and connection mode.

[0111] Among them, the opposite device includes but is not limited to the second device and the third device mentioned above. The device identification includes, for example, the device name, the network address, etc. The protocol types include but are not limited to IEEE802.11a, 802.11b, 802.11n, 802.11ac, 802.11ax, and some other self-developed protocols. The connection modes include automatic connection, manual connection, etc. Automatic connection means that when the first device detects that the conditions for establishing a connection are met, the first device can directly connect to the device without manual triggering by the user; manual connection means that a connection can be established with the device only after an operation based on user input to establish a connection.

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

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

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

[0115] Specifically, after the first device detects the connection status of the established connection, if it detects that the connection status does not meet the stable state, it will perform the connection self-healing as described in S33 and S35 above. Therefore, the first device will also store the connection self-healing data, and 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 successful self-healings, the time required for successful self-healing, the number of self-healings within a preset time, etc. corresponding to the self-healing object (device identifier) ​​and the self-healing time.

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

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

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

[0119] In the embodiment of the present application, the present application does not limit the order in which the first device executes S41-S44. The first device can execute S41-S44 simultaneously or in any other order, and the embodiment of the present application does not limit this.

[0120] S45: The first device determines the priority of each device based on any one or more factors of connection status detection data with each device, connection self-healing data, or user's preference for frequently connected devices.

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

[0122] When the first device comprehensively determines the priority based on the above-mentioned connection status detection data, connection self-healing data, and user's frequently connected device preferences, the priority can be determined illustratively by sorting the following factors in order of importance from high to low: connection signal strength, user preference, number of connection self-healing times and time required for successful self-healing, and number of self-healings within a preset time (i.e., the number of times the connection status does not meet the stable state within the preset time).

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

[0124] The software system of the first device can adopt a layered architecture, an event-driven architecture, a micro-kernel architecture, a micro-service architecture, or a cloud architecture. Taking the system as an example, the software structure of the first device is exemplified.

[0125] Figure 5 It is a schematic diagram of the software architecture of the first device of an embodiment of the present application.

[0126] The layered architecture divides the software into several layers, each with a clear role and division of labor. The layers communicate with each other through software interfaces. The system is divided into four layers, from top to bottom: application layer, application framework layer, Android runtime ( 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 connection application (also referred to as a first application), and Figure 5 Automated tests not shown are for applications such as Camera, Gallery, Calendar, Calls, Maps, Navigation, WLAN, Bluetooth, Music, Video, SMS, etc.

[0129] Among them, the name of the wireless connection application is only an example, which 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 connection applications include but are not limited to the following modules: connection 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 coding protocol, and based on the parsed device information, establish a wireless connection with the device according to the coding 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 IEEE802.11a, 802.11b, 802.11n, 802.11ac, 802.11ax, etc. The self-developed protocol is mainly used for the electronic device 100 to establish a wireless connection with other devices to realize wireless functions.

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

[0134] The self-healing module is mainly used to perform 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 initial self-healing fails, that is, controlling the wireless connection module to power off and then power on again to establish a connection. In addition, the self-healing module is also used to store the self-healing data for the optimization module to prioritize the devices that can be connected.

[0135] The optimization module is mainly used to prioritize multiple devices that can be connected, and to select the device with the highest priority from the connectable devices to establish a connection after the self-healing module fails to further self-heal.

[0136] The update module is mainly used to update 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 the first preset ratio, the connection detection conditions are relaxed, such as increasing the preset duration of the connectivity test, and / or reducing the signal strength less than the preset strength, that is, changing the stable state from the original first stable state to the second stable state. The range of the second stable state is greater than the range of the first stable state, so that the detection conditions are too strict and affect the normal communication of the electronic device 100; when the connection self-healing data indicates that the connection self-healing success rate of the first device is higher than the second preset ratio, the connection detection conditions are narrowed, such as reducing the preset duration of the connectivity test, and / or increasing the signal strength less than the preset strength, that is, changing the stable state from the original first stable state to the second stable state. The range of the second stable state is less than the range of the first stable state. Among them, the first preset ratio is less than the second preset ratio, so that the established wireless connection can be guaranteed to have high stability and high quality, and improve the user experience.

[0137] Among them, the automated test is usually used in the production line of the electronic device 100. After the product is launched, the automated test is not provided at the user end, so it is not elaborated here.

[0138] The application framework layer provides an application programming interface (API) and a programming framework for the applications in the application layer. The application framework layer includes some predefined functions.

[0139] like Figure 5 As shown, the application framework layer may include a Wi-Fi interface, a BT interface, and Figure 5 Not shown are the window manager, content provider, view system, telephony manager, resource manager, notification manager, etc.

[0140] The WiFi interface is used to control the services issued by the lower-layer WiFi driver based on the calls of the upper-layer applications.

[0141] The BT interface is used to control the services issued by the lower-layer WiFi driver based on the calls of the upper-layer applications.

[0142] The window manager is used to manage window programs. The window manager can obtain the display screen size, determine whether there is a status bar, lock the screen, capture the screen, etc.

[0143] Content providers are used to store and retrieve data and make it accessible to applications. The data may include videos, images, audio, calls made and received, browsing history and bookmarks, phone books, etc.

[0144] The view system includes visual controls, such as controls for displaying text, controls for displaying images, etc. The view system can be used to build applications. A display interface can be composed of one or more views. For example, a display interface including a text notification icon can include a view for displaying text and a view for displaying images.

[0145] The phone manager is used to provide the communication function of the first device, such as the management of the call status (including connecting, hanging up, etc.).

[0146] The resource manager provides various resources for applications, such as localized strings, icons, images, layout files, video files, and so on.

[0147] The notification manager enables applications to display notification information in the status bar. It can be used to convey notification-type messages and can disappear automatically after a short stay without user interaction. For example, the notification manager is used to notify download completion, message reminders, etc. The notification manager can also be a notification that appears in the system top status bar in the form of a chart or scroll bar text, such as notifications of applications running in the background, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in the status bar, a prompt sound is emitted, the first device vibrates, the indicator light flashes, etc.

[0148] Android runtime includes core libraries and virtual machines. Android runtime is responsible for scheduling and management of the Android system.

[0149] The core library consists of two parts: one part is the function that needs to be called by the Java language, and the other part is the Android core library.

[0150] The application layer and the application framework layer run in a virtual machine. The virtual machine executes the Java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

[0151] The system library may include multiple functional modules, such as surface manager, media library, 3D graphics processing library (such as OpenGL ES), 2D graphics engine (such as SGL), etc.

[0152] The surface manager is used to manage the display subsystem and provide the fusion of 2D and 3D layers for multiple applications.

[0153] The media library supports playback and recording of a variety of commonly used audio and video formats, as well as static image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

[0154] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

[0155] A 2D graphics engine is a drawing engine for 2D drawings.

[0156] The kernel layer is the layer between hardware and software. The kernel layer contains at least Wi-Fi driver, BT driver, display driver, camera driver, and Figure 5 Audio driver, sensor driver, etc. not shown.

[0157] The electronic device 100 can call the WiFi interface through the upper-layer wireless connection apk to control the operation of the Wi-Fi driver. The WiFi driver can be used to control the operation of the Wi-Fi chip, thereby establishing a Wi-Fi connection.

The memory may store instructions or data that the processor 110 has just used or cyclically used. If the processor 110 needs to use the instruction or data again, it may be directly called from the memory. This avoids repeated access, reduces the waiting time of the processor 110, and thus improves the efficiency of the system.

[0164] In the embodiment of the present application, the electronic device 100 can call other software and hardware modules through the processor 110 to execute the above Figure 3-Figure 4 The connection methods introduced are not described in detail here.

[0168] It is understandable that the interface connection relationship between the modules illustrated in the embodiment of the present application is only a schematic illustration and does not constitute a structural limitation on the electronic device 100. In other embodiments of the present application, the electronic device 100 may also adopt different interface connection methods in the above embodiments, or a combination of multiple interface connection methods.

[0171] The wireless communication function of the electronic device 100 can be implemented through the antenna 1, the antenna 2, the mobile communication module 150, the wireless communication module 160, the modem processor and the baseband processor.

[0172] Antenna 1 and antenna 2 are used to transmit and receive electromagnetic wave signals.

For example, antenna 1 can be reused as a diversity antenna for a wireless local area network. In some other embodiments, the antenna can be used in combination with a tuning switch.

[0173] The mobile communication module 150 can provide solutions for wireless communications including 2G / 3G / 4G / 5G, etc., applied to the electronic device 100. The mobile communication module 150 may include at least one filter, a switch, a power amplifier, a low noise amplifier (LNA), etc. The mobile communication module 150 can receive electromagnetic waves from the antenna 1, and filter, amplify, and process the received electromagnetic waves, and transmit them to the modulation and demodulation processor for demodulation.

The demodulator is used to demodulate the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After the low-frequency baseband signal is processed by the baseband processor, it is passed to the application processor. The application processor outputs a sound signal through an audio device (not limited to a speaker 170A, a receiver 170B, etc.), or displays an image or video through a display screen 194. In some embodiments, the modem processor may be an independent device. In other embodiments, the modem processor may be independent of the processor 110 and be set in the same device as the mobile communication module 150 or other functional modules.

The wireless communication module 160 can be one or more devices integrating at least one communication processing module. The wireless communication module 160 receives electromagnetic waves via the antenna 2, demodulates and filters the electromagnetic wave signals, and sends the processed signals to the processor 110. The wireless communication module 160 can also receive the signal to be sent from the processor 110, modulate the frequency, amplify it, and convert it into electromagnetic waves for radiation through the antenna 2.

[0176] In some embodiments, the antenna 1 of the electronic device 100 is coupled to the mobile communication module 150, and the antenna 2 is coupled to the wireless communication module 160, so that the electronic device 100 can communicate with the network and other devices through wireless communication technology.

The light signal is converted into an electrical signal, and the camera photosensitive element transmits the electrical signal to the ISP for processing and converts it into an image visible to the naked eye. The ISP can also perform algorithm optimization on the noise and brightness of the image. The ISP can also optimize the exposure, color temperature and other parameters of the shooting scene. In some embodiments, the ISP can be set in the camera 193.

[0182] The camera 193 is used to capture still images or videos. The object generates an optical image through the lens and projects it onto the photosensitive element. The photosensitive element can be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, and then passes the electrical signal to the ISP to be converted into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV or other format. In some embodiments, the electronic device 100 may include 1 or N cameras 193, where N is a positive integer greater than 1.

[0192] The non-volatile memory may also store executable programs and user and application data, etc., and may be loaded into the random access memory in advance for direct reading and writing by the processor 110 .

[0193] The external memory interface 120 can be used to connect to an external non-volatile memory to expand the storage capacity of the electronic device 100. The external non-volatile memory communicates with the processor 110 through the external memory interface 120 to implement a data storage function. For example, files such as music and videos are stored in the external non-volatile memory.

[0194] In an embodiment of the present application, the electronic device 100 can store wireless connection related data through the above-mentioned memory, including but not limited to: connection device identification, connection status detection data, connection self-healing data, user's frequently connected device preference and priority, etc.

[0200] The earphone interface 170D is used to connect a wired earphone and can be a USB interface 130 or a 3.5 mm open mobile terminal platform (OMTP) standard interface or a cellular telecommunications industry association of the USA (CTIA) standard interface.

[0201] The pressure sensor 180A is used to sense the pressure signal and can convert the pressure signal into an electrical signal. In some embodiments, the pressure sensor 180A can be set on the display screen 194. There are many types of pressure sensors 180A, such as resistive pressure sensors, inductive pressure sensors, capacitive pressure sensors, etc. The capacitive pressure sensor can be a parallel plate including at least two conductive materials. When a force acts on 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 acts on the display screen 194, the electronic device 100 detects the touch operation intensity according to the pressure sensor 180A. The electronic device 100 can also calculate the touch position according to the detection signal of the pressure sensor 180A. In some embodiments, touch operations acting on 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 the first pressure threshold acts on the short message application icon, an instruction to view the short message is executed. When a touch operation with a touch operation intensity greater than or equal to the first pressure threshold acts on the short message application icon, an instruction to create a new short message is executed.

[0202] The touch sensor 180B is also called a "touch panel". The touch sensor 180B can be arranged on the display screen 194, and the touch sensor 180B and the display screen 194 form a touch screen, also called a "touch screen". The touch sensor 180B is used to detect touch operations acting on or near it. The touch sensor can pass 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 arranged on the surface of the electronic device 100, which is different from the position of the display screen 194.
