Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of terminal, in particular to a device connection method and related device. BACKGROUND

[0002] In order to meet the file transmission requirement between the wearable device and the mobile terminal (for example, a mobile phone), the communication connection needs to be established between the wearable device and the mobile terminal. Generally, the communication connection is a short distance communication connection, for example, a Bluetooth connection. However, the file is transmitted through the Bluetooth, which is low in efficiency and long in time, and affects the user experience. SUMMARY

[0003] Embodiments of the present application provide a device connection method and related device, which can establish the Wi-Fi connection between the wearable device and the mobile terminal, and improve the transmission efficiency.

[0004] In the first aspect, a device connection method is provided and applied to a wearable device. The wearable device can be a watch, a bracelet, etc. The method comprises: the wearable device determines that a first condition is met, the first condition can comprise: an operating system of a mobile terminal is a preset operating system, the preset operating system is different from an operating system of the wearable device, or a first Wi-Fi hotspot created by the mobile terminal cannot be searched, or the first Wi-Fi hotspot created by the mobile terminal cannot be connected. The wearable device creates a second Wi-Fi hotspot. The wearable device sends information of the second Wi-Fi hotspot to the mobile terminal, the information of the second Wi-Fi hotspot is used for the mobile terminal to establish a second Wi-Fi connection with the wearable device.

[0005] In view of the lightweight design requirement of the wearable device, generally, the wearable device is not a sender of a Wi-Fi hotspot, i.e., the wearable device has no capability of creating a Wi-Fi hotspot. Therefore, the wearable device can only passively search for a Wi-Fi hotspot of the mobile terminal, and then establish a Wi-Fi connection with the mobile terminal. This passive searching and connecting scheme is not applicable in some scenarios. For example, the wearable device and the mobile terminal have different operating systems, e.g., the mobile terminal is an IOS system, and the wearable device is a Harmony system or an Android system. In this case, the wearable device can not search for or can not connect to the Wi-Fi hotspot of the mobile terminal, resulting in that the wearable device and the mobile terminal can not establish a Wi-Fi connection. In the embodiments of the present application, the wearable device can be a sender of a Wi-Fi hotspot, i.e., the wearable device can create a Wi-Fi hotspot. For example, the wearable device can create a second Wi-Fi hotspot to enable the mobile terminal to establish a second Wi-Fi connection with the wearable device in a case where it is determined that a first condition is met. This scheme can be applicable to a scenario where the wearable device and the mobile terminal have different operating systems (e.g., the mobile terminal is an IOS system, and the wearable device is a Harmony system or an Android system), and overcomes the situation that the wearable device and the mobile terminal can not establish a Wi-Fi connection in the scenario.

[0006] In a possible design, before the wearable device creates the second Wi-Fi hotspot, the method further includes: determining that the wearable device meets a second condition, the second condition including at least one of the following: a current service scenario is a preset scenario; a current running load is lower than a load threshold; a current remaining power is higher than a power threshold; a format of a to-be-transmitted file is a preset format; and a file amount of the to-be-transmitted file is greater than a preset data amount.

[0007] In the embodiments of the present application, in view of the fact that creating the second Wi-Fi hotspot will generate certain power consumption, in order to avoid power consumption waste, the wearable device creates the second Wi-Fi hotspot only in a case where the second condition is met, which is helpful to guarantee the endurance of the wearable device.

[0008] In a possible design, the second condition includes that the current service scenario is the preset scenario, and the preset scenario includes one of the following: a system upgrade scenario, a theme update scenario, a wallpaper update scenario, an application upgrade scenario, and an offline map scenario.

[0009] In the embodiments of the present application, in view of the fact that creating the second Wi-Fi hotspot will generate certain power consumption, in order to avoid power consumption waste, the wearable device creates the second Wi-Fi hotspot only when the current service scenario of the wearable device is the system upgrade scenario, the theme update scenario, the wallpaper update scenario, the application upgrade scenario, or the offline map scenario, which is helpful to guarantee the endurance of the wearable device.

[0010] In a possible design, before the wearable device sends the information of the second Wi-Fi hotspot to the mobile terminal, the method further includes: the wearable device establishing a Bluetooth connection with the mobile terminal; and the wearable device sending the information of the second Wi-Fi hotspot to the mobile terminal, including: the wearable device sending the information of the second Wi-Fi hotspot to the mobile terminal through the Bluetooth connection.

[0011] In an embodiment of the present application, the wearable device can send the information of the second Wi-Fi hotspot to the mobile terminal through Bluetooth, so that the mobile terminal establishes a second Wi-Fi connection with the wearable device, and in this process, the user does not need to perform too many operations, thereby improving operation convenience.

[0012] In a possible design, after the wearable device sends the information of the second Wi-Fi hotspot to the mobile terminal through the Bluetooth connection, the method further includes: the wearable device disconnecting the Bluetooth connection between the wearable device and the mobile terminal.

[0013] In an embodiment of the present application, in order to reduce power consumption and avoid interference of Bluetooth signals on Wi-Fi signals, after the wearable device sends the information of the second Wi-Fi hotspot to the mobile terminal through Bluetooth, the wearable device can disconnect the Bluetooth connection between the wearable device and the mobile terminal.

[0014] In a possible design, before the wearable device creates the second Wi-Fi hotspot, the method further includes: the wearable device displaying first prompt information, where the first prompt information is used to prompt the user to confirm whether to create the second Wi-Fi hotspot; and the wearable device receiving a confirmation instruction for creating the second Wi-Fi hotspot.

[0015] In an embodiment of the present application, considering that creating the second Wi-Fi hotspot will generate certain power consumption, for example, the power-off speed of the wearable device can be accelerated. If the second Wi-Fi hotspot is created without the user's knowledge, the user experience will be affected. Therefore, the wearable device can output prompt information, and create the second Wi-Fi hotspot after obtaining the user's consent, thereby improving user experience.

[0016] In a possible design, the first condition includes that the operating system of the mobile terminal is a preset operating system, and the method further includes: the wearable device determining that the operating system of the mobile terminal is not the preset operating system; the wearable device requesting the mobile terminal to create the first Wi-Fi hotspot; the wearable device receiving the information of the first Wi-Fi hotspot sent by the mobile terminal; and the wearable device establishing a first Wi-Fi connection with the mobile terminal based on the information of the first Wi-Fi hotspot.

[0017] In the embodiments of the present application, the wearable device can determine whether the device itself is a sender or a receiver of the Wi-Fi hotspot. For example, when the wearable device determines that the operating system of the mobile terminal is not the preset operating system, the wearable device determines that the device itself should be a receiver of the Wi-Fi hotspot. Therefore, the wearable device can request the mobile terminal to create a first Wi-Fi hotspot, so that the wearable device establishes a first Wi-Fi connection with the mobile terminal. In this way, the wearable device does not need to create a Wi-Fi hotspot, and the power consumption of the wearable device can be saved.

[0018] In a possible design, before the wearable device requests the mobile terminal to create the first Wi-Fi hotspot, the method further includes: the wearable device determines that the first Wi-Fi hotspot of the mobile terminal cannot be searched.

[0019] In the embodiments of the present application, the wearable device can determine whether the device itself is a sender or a receiver of the Wi-Fi hotspot. If the device itself is determined to be a receiver of the Wi-Fi hotspot, the wearable device can search for a first Wi-Fi hotspot of a mobile terminal. If the first Wi-Fi hotspot of the mobile terminal is not searched, the wearable device can request the mobile terminal to create the first Wi-Fi hotspot, so that the wearable device establishes a first Wi-Fi connection with the mobile terminal. In this way, the wearable device does not need to create a Wi-Fi hotspot, and the power consumption of the wearable device can be saved.

[0020] As described above, the second Wi-Fi connection is established based on a second Wi-Fi hotspot created by the watch, and the first Wi-Fi connection is established based on a first Wi-Fi hotspot created by the mobile phone. Therefore, the second Wi-Fi connection is different from the first Wi-Fi connection, for example, the transmission resources corresponding to the second Wi-Fi connection and the first Wi-Fi connection are different, the modulation and coding modes are different, and the like. The transmission resources can include a transmission bandwidth, for example, a frequency bandwidth.

[0021] In a possible design, the information of the second Wi-Fi hotspot includes: a name and a password of the second Wi-Fi hotspot.

[0022] Optionally, the name and the password of the second Wi-Fi hotspot can be generated by the wearable device or set by a user, which are not limited.

[0023] In a possible design, the operating system of the wearable device is a Harmony operating system or an Android operating system, and the operating system of the mobile terminal is an IOS operating system.

[0024] It should be noted that, taking the mobile terminal as an IOS system and the wearable device as a Harmony system or an Android system as an example, the wearable device can not search for or can not connect to the Wi-Fi hotspot created by the mobile terminal, so that the mobile terminal and the wearable device can not establish a Wi-Fi connection. In this case, the device connection method provided in the embodiments of the present application can enable the wearable device and the mobile terminal to establish a Wi-Fi connection, which helps to improve the file transmission rate.

[0025] In a possible design, the wearable device can not search for the first Wi-Fi hotspot created by the mobile terminal, including: after the wearable device sends a creation request of the first Wi-Fi hotspot to the mobile terminal, the wearable device can not search for the first Wi-Fi hotspot created by the mobile terminal.

[0026] In the embodiments of the present application, the wearable device can attempt whether the wearable device can search for the first Wi-Fi hotspot created by the mobile terminal, and optionally, one or more attempts can be performed. For example, when the wearable device attempts to search for the first Wi-Fi hotspot for the first time but fails to search for the first Wi-Fi hotspot, the wearable device can attempt to search for the first Wi-Fi hotspot for the second time. Optionally, before the wearable device attempts to search for the first Wi-Fi hotspot for the second time, the wearable device can request the mobile terminal to create the first Wi-Fi hotspot. After the request, if the wearable device still fails to search for the first Wi-Fi hotspot created by the mobile terminal, the wearable device can attempt to search for the first Wi-Fi hotspot for the next time or stop attempting to search for the first Wi-Fi hotspot.

[0027] The second aspect further provides a wearable device, including: a processor, a memory, and one or more programs; wherein the one or more programs are stored in the memory, and the one or more programs include instructions, when the instructions are executed by the processor, the wearable device performs the following method steps:

[0063] References to "one embodiment," "in some examples," or "some embodiments" as described in the embodiments of this application mean that one or more embodiments of this specification include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in some examples," "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0064] The device connection method provided in this application can be applied to communication systems. For example, please refer to [link to relevant documentation]. Figure 1 This is a schematic diagram of a communication system provided in an embodiment of this application. Figure 1 As shown, the communication system includes a first device and a second device.

[0065] The first device can be a mobile terminal. A mobile terminal can be a mobile phone, tablet computer, laptop computer, personal computer (PC), ultra-mobile personal computer (UMPC), netbook, personal digital assistant (PDA), or other portable devices; or it can be a wearable device such as a watch or bracelet; or it can be an in-vehicle device; or it can be a home appliance such as a television set; or it can be a virtual reality (VR) device, augmented reality (AR) device, mixed reality (MR) device, etc. In short, the specific type of mobile terminal is not limited in this application embodiment. The operating system of the first device can be a first operating system. For example, the first operating system can be Android. System, HarmonyOS system, system, system, system, system, system, Any operating system, including the system itself.

[0066] In the embodiments of the present application, the first device comprises a first short-distance communication module. The first short-distance communication module can comprise a first Bluetooth module and / or a first Wi-Fi module. The first Bluetooth module is configured to establish a first Bluetooth connection with another device (e.g., the second device). The first Wi-Fi module is configured to establish a first Wi-Fi connection with another device (e.g., the second device). For example, the first Wi-Fi module can create a first Wi-Fi hotspot to enable another device (e.g., the second device) to establish a first Wi-Fi connection therewith. Alternatively, the first Wi-Fi module can also search for a second Wi-Fi hotspot created by another device (e.g., the second device) and establish a second Wi-Fi connection therewith. The process of establishing a Wi-Fi connection between the first device and the second device will be described in detail later. It should be noted that the "Wi-Fi connection" (including the first Wi-Fi connection and the second Wi-Fi connection) herein is a device-to-device connection, i.e., a point-to-point connection, and does not require an end-to-end (e.g., cloud or server) to establish a connection. Therefore, the "Wi-Fi connection" herein can also be referred to as "Wi-Fi direct connection", "Wi-Fi-based P2P connection", etc., and the name is not limited herein.

[0067] It should be understood that whether it is a Bluetooth connection or a Wi-Fi connection, the signal needs to be transmitted and received through an antenna. Optionally, the first Bluetooth module and the first Wi-Fi module can correspond to the same antenna or different antennas, and the embodiments of the present application are not limited. Taking the case where the first Bluetooth module and the first Wi-Fi module correspond to the same antenna as an example, the first Bluetooth module and the first Wi-Fi module can adopt a time-sharing manner to transmit and receive signals through the antenna. For example, in one time period, the first Bluetooth module transmits and receives signals through the antenna, and in another time period, the first Wi-Fi module transmits and receives signals through the antenna. Taking the case where the first Bluetooth module and the first Wi-Fi module correspond to different antennas as an example, for example, the first Bluetooth module corresponds to antenna 1, and the first Wi-Fi module corresponds to antenna 2, i.e., the first Bluetooth module transmits and receives signals through antenna 1, and the first Wi-Fi module transmits and receives signals through antenna 2.

[0068] The second device can be a wearable device. The wearable device can include a wristband device, a head-mounted device, a clothing device, etc. The wristband device can include a watch, a bracelet, a glove, a wristband, a necklace, a ring, etc. The head-mounted device can include glasses, a helmet, an earplug, an earphone, etc. The clothing device can include clothes, shoes, a button, etc. In summary, the embodiments of the present application do not limit the specific type of the wearable device. The operating system of the second device can be a second operating system. For example, the second operating system can be an Android system, a Harmony system, System, System, System, System, System, System, etc.

[0069] In the embodiments of the present application, the second device comprises a second short-distance communication module. The second short-distance communication module can comprise a second Bluetooth module and / or a second Wi-Fi module. The second Bluetooth module is used to establish a second Bluetooth connection with other devices (e.g., the first device). The second Wi-Fi module is used to establish a second Wi-Fi connection with other devices (e.g., the first device). For example, the second Wi-Fi module can create a second Wi-Fi hotspot to enable other devices (e.g., the first device) to establish a second Wi-Fi connection therewith. Alternatively, the second Wi-Fi module can also search for a first Wi-Fi hotspot created by other devices (e.g., the first device) and establish a first Wi-Fi connection therewith. The process of establishing a Wi-Fi connection between the first device and the second device will be described in detail hereinafter. Optionally, the second Bluetooth module and the second Wi-Fi module can correspond to the same antenna or different antennas, and the principle is the same as that of the first device described above, which will not be repeated here.

[0070] The following will continue to be described with reference to the communication system shown in Figure 1 The first device is taken as an example of a mobile phone, and the second device is taken as an example of a watch.

[0071] As described above, in order to meet the file transmission requirement between the watch and the mobile phone, a communication connection needs to be established between the watch and the mobile phone. In order to improve the transmission efficiency, the communication connection can be a short-distance communication connection. The short-distance communication connection can comprise a Bluetooth connection, a Wi-Fi connection, and of course, other connection modes such as a near field communication (NFC) connection. Taking the Bluetooth connection as an example, after the watch and the watch establish a Bluetooth connection, the files are transmitted through Bluetooth. However, the Bluetooth transmission of files is time-consuming and inefficient, especially when transmitting a large amount of data, a long waiting time is required before the transmission is completed. Compared with the Bluetooth connection, the Wi-Fi connection has high transmission efficiency and short time consumption, so the Wi-Fi connection is mainly taken as an example for description in the present application. The process of establishing a Wi-Fi connection between the watch and the mobile phone will be described hereinafter.

[0072] For the convenience of understanding, the principle of establishing Wi-Fi connection between two devices is briefly described. To establish Wi-Fi connection, one of the two devices acts as the sender of Wi-Fi hotspot, and the other acts as the receiver of Wi-Fi hotspot. Of course, the sender of Wi-Fi hotspot can also be called the creator or provider of Wi-Fi hotspot. The receiver of Wi-Fi hotspot can also be called the searcher or enjoyer of Wi-Fi hotspot. Taking two devices including device A and device B as an example, if device A acts as the sender of Wi-Fi hotspot and device B acts as the receiver of Wi-Fi hotspot, device A is responsible for creating Wi-Fi hotspot so that device B establishes Wi-Fi connection with it; if device B acts as the sender of Wi-Fi hotspot and device A acts as the receiver of Wi-Fi hotspot, device B is responsible for creating Wi-Fi hotspot so that device A establishes Wi-Fi connection with it.

[0073] Therefore, to establish Wi-Fi connection between the watch and the mobile phone, one of the two devices acts as the sender of Wi-Fi hotspot, and the other acts as the receiver of Wi-Fi hotspot. In this regard, the embodiments of the present application can include the following two schemes.

[0074] The first scheme is that the watch acts as the receiver of Wi-Fi hotspot and the mobile phone acts as the sender of Wi-Fi hotspot.

[0075] For example, the mobile phone creates a first Wi-Fi hotspot so that the watch establishes a first Wi-Fi connection with it. In this scheme, since the watch acts as the receiver of Wi-Fi hotspot, it does not need to create a Wi-Fi hotspot, which helps to save the power consumption of the watch, and the watch does not need to be configured with software / hardware for creating a Wi-Fi hotspot, which is in line with the lightweight trend of the watch.

[0076] Optionally, in the first scheme, the watch and the mobile phone establishing the first Wi-Fi connection can include two ways: automatic connection and manual connection.

[0077] The first way is manual connection. For example, please refer to Figure 2A (a), the mobile phone displays an interface. Optionally, the interface can be the interface of the setting application in the mobile phone. The interface includes a button, which is used to trigger the mobile phone to create a first Wi-Fi hotspot or to close the first Wi-Fi hotspot. When the mobile phone receives an operation on the button, it displays an interface as Figure 2A (b) and creates a first Wi-Fi hotspot. At this time, the mobile phone can broadcast a signal to the outside, which includes the name of the first Wi-Fi hotspot. The watch can search for the first Wi-Fi hotspot and display an interface as Figure 2A(c) the interface shown, which includes the name of the first Wi-Fi hotspot searched for. After the watch receives the operation for the name of the first Wi-Fi hotspot, it pairs with the phone and establishes the first Wi-Fi connection. For example, the watch can send a pairing request to the phone. After the phone receives the pairing request, it can display an interface as shown in Figure 2A (d) the interface shown, which can include a prompt message: whether to pair with the watch. After the phone receives the confirmation instruction, it pairs with the watch and sends a response of pairing success to the watch. After the watch receives the response, it can display an interface as shown in Figure 2A (e) the interface shown, which includes a prompt message: pairing with the phone is completed. Thus, the watch establishes the first Wi-Fi connection with the phone.

[0078] The second way is automatic connection. For example, please refer to Figure 2B , a flowchart of a device connection method provided by an embodiment of the present application. The method can be applied to Figure 1 the communication system shown. As shown in Figure 2B , the flowchart can include the following steps:

[0079] S201, the phone creates a first Wi-Fi hotspot.

[0080] S202, the phone broadcasts a signal, which includes the name of the first Wi-Fi hotspot.

[0081] Optionally, the name of the first Wi-Fi hotspot can be the service set identifier (SSID) of the first Wi-Fi hotspot. Optionally, the name can be generated by the phone itself or set by a user, without limitation.

[0082] S203, the watch searches for the first Wi-Fi hotspot.

[0083] It should be noted that after the watch searches for the first Wi-Fi hotspot of the phone, if it wants to automatically establish the first Wi-Fi connection with the phone, it also needs to know the connection information of the first Wi-Fi hotspot, which is used to connect to the first Wi-Fi hotspot. Exemplarily, the connection information of the first Wi-Fi hotspot can include the password of the first Wi-Fi hotspot, and optionally, the name of the first Wi-Fi hotspot. The password can be a combination of one or more of numerical value, letter, symbol, etc. The password can be generated by the phone itself or set by a user, without limitation. In the embodiment of the present application, the watch can receive the connection information of the first Wi-Fi hotspot from the phone through Bluetooth, i.e., S204 and S205.

[0084] S204, the watch establishes a Bluetooth connection with the phone.

[0085] Optionally, the execution sequence of S204 and S201-S203 is not limited, for example, S204 can be executed before S201.

[0086] S205, the mobile phone sends the connection information of the first Wi-Fi hotspot to the watch through Bluetooth.

[0087] S206, the watch establishes the first Wi-Fi connection with the mobile phone based on the connection information of the first Wi-Fi hotspot.

[0088] S207, the mobile phone disconnects the Bluetooth connection between the mobile phone and the watch.

[0089] Optionally, S207 can be executed or not executed, so the figure uses a dashed line to represent. In addition, the execution sequence between S207 and S206 is not limited. It should be understood that the mobile phone disconnects the Bluetooth connection between the mobile phone and the watch, which helps to save power consumption, and also avoids the interference of Bluetooth signal to Wi-Fi signal.

[0090] Figure 2B In the embodiment shown, after the mobile phone creates the first Wi-Fi hotspot, the mobile phone can provide the information of the first Wi-Fi hotspot (for example, the name and password of the first Wi-Fi hotspot) to the watch, and the watch establishes the first Wi-Fi connection with the mobile phone based on the information of the first Wi-Fi hotspot. In this way, the user does not need to manually operate, and the automatic establishment of the first Wi-Fi connection is realized, which improves the convenience.

[0091] In the above embodiment, two implementation manners of the first scheme are described. Since the mobile phone is the sender of the Wi-Fi hotspot in the first scheme, the mobile phone can select one of the two implementation manners. There can be many selection methods. Method A, a display component is provided in the mobile phone to facilitate the user to set an automatic connection mode or a manual connection mode, if the user sets the automatic connection mode, the automatic connection manner is adopted, if the user sets the manual connection mode, the manual connection manner is adopted. Method B, the mobile phone can judge whether the Bluetooth connection has been established at present, if yes, the automatic connection manner is adopted, otherwise, the manual connection manner is adopted.

[0092] In some embodiments, the first solution described above can be applicable to the scenario where the phone and the watch have the same operating system. For example, the watch and the phone are both a Harmony system or both an Android system or both an IOS system. A possible case is that the phone and the watch with the same operating system belong to the same manufacturer (for example, Huawei), and the watch and the phone provided by the same manufacturer can use the first solution described above to establish a Wi-Fi connection. For the scenario where the phone and the watch have different operating systems, the first solution described above can not be applicable. For example, the watch is a first operating system and the phone is a second operating system. The first operating system and the second operating system are different, for example, the first operating system is a Harmony system or an Android system, and the second operating system is an IOS system. In this case, the watch as the receiver of the Wi-Fi hotspot and the phone as the sender of the Wi-Fi hotspot can not be able to establish a Wi-Fi connection. A possible case is that the watch cannot search for the Wi-Fi hotspot created by the phone. For example, as shown in Figure 3A (a), the phone creates a Wi-Fi hotspot, but the watch cannot search for the Wi-Fi hotspot created by the phone, as shown in Figure 3A (b). Another possible case is that the watch can search for the Wi-Fi hotspot created by the phone but cannot connect to the Wi-Fi hotspot. For example, as shown in Figure 3B (a), the phone creates a Wi-Fi hotspot, and the watch can search for the Wi-Fi hotspot created by the phone, as shown in Figure 3B (b). However, the watch cannot establish a Wi-Fi connection when it receives the operation for connecting to the Wi-Fi hotspot. For example, as shown in Figure 3B (c), the watch displays a prompt message of "connection failed". The reason for the above-mentioned case can be that the second operating system of the phone restricts the wearable device (for example, the watch of the first operating system) of the non-second operating system from establishing a Wi-Fi connection with it.

[0093] Through analysis, it can be known that the reason why the watch and the phone described above cannot establish a Wi-Fi connection is that the watch as the receiver of the Wi-Fi hotspot can only passively search for the Wi-Fi hotspot of the phone, and once a special case (for example, the operating system of the phone is an IOS system, and the operating system of the watch is a Harmony system or an Android system) occurs, the watch cannot establish a Wi-Fi connection with the phone. In order to solve this problem, an embodiment of the present application provides a solution, in which the watch is not limited to only passively searching for the Wi-Fi hotspot of the phone, and the watch can also create a Wi-Fi hotspot. In other words, the watch as the sender of the Wi-Fi hotspot and the phone as the receiver of the Wi-Fi hotspot, that is, the second solution described below.

[0094] The second solution is that the watch as the sender of the Wi-Fi hotspot and the phone as the receiver of the Wi-Fi hotspot.

[0095] For example, the watch creates a second Wi-Fi hotspot to enable the phone to establish a second Wi-Fi connection with the watch. The second solution can be applicable to the scenario where the phone and the watch have the same operating system. For example, the watch and the phone are both a Harmony system or both an Android system or both an IOS system. The second solution can also be applicable to the scenario where the phone and the watch have different operating systems. Continuing the previous example, the watch is a first operating system, for example, a Harmony system or an Android system, and the phone is a second operating system, for example, an IOS system, in the case where the watch is the sender of the Wi-Fi hotspot and the phone is the receiver of the Wi-Fi hotspot, the two can establish a Wi-Fi connection. For example, after the watch creates a second Wi-Fi hotspot, the phone can search for the second Wi-Fi hotspot created by the watch and can connect to the second Wi-Fi hotspot.

[0096] Optionally, in the second solution, the watch and the phone establish a second Wi-Fi connection, including automatic connection and manual connection.

[0097] The first way is manual connection. For example, please refer to Figure 4A (a), the watch display interface. Optionally, the interface can be the interface of the settings application in the watch. The interface includes a button, which is used to trigger the watch to create a second Wi-Fi hotspot or to trigger the watch to close the second Wi-Fi hotspot. Figure 4A In (a), when the watch receives an operation on the button, it displays an interface as shown in Figure 4A (b) and creates a second Wi-Fi hotspot. At this time, the watch can broadcast a signal to the outside, which includes the name of the second Wi-Fi hotspot. The phone can search for the second Wi-Fi hotspot, and after searching for the second Wi-Fi hotspot, it displays an interface as shown in Figure 4A (c), which includes the name of the searched second Wi-Fi hotspot. After the phone receives an operation on the name of the second Wi-Fi hotspot, it pairs with the watch and establishes a second Wi-Fi connection. For example, the phone can send a pairing request to the watch. After the watch receives the pairing request, it can display an interface as shown in Figure 4A (d), which can include a prompt message: whether to pair with the phone. After the watch receives a confirmation instruction, it pairs with the phone and sends a pairing success response to the phone, and after the phone receives the response, it can display an interface as shown in Figure 4A (e), which includes a prompt message: pairing with the watch is completed.

[0098] The second way is automatic connection. For example, please refer to Figure 4B , another flowchart of the device connection method provided by the embodiments of the present application. The method can be applicable toFigure 1 The communication system is illustrated. As Figure 4B The flow can include:

[0099] S401, the watch creates a second Wi-Fi hotspot.

[0100] In some embodiments, before creating the second Wi-Fi hotspot, the watch can further determine whether a second condition is met, and if so, create the second Wi-Fi hotspot. Optionally, the second condition includes at least one of the following:

[0101] I. The current service scenario of the watch is a preset scenario. Illustratively, the preset scenario can include at least one of the following: a system upgrade scenario, a theme update scenario, a wallpaper update scenario, an application upgrade scenario, and an offline map scenario, which are described below respectively.

[0102] (a) The system upgrade scenario, i.e., a scenario in which the operating system of the watch is upgraded. The operating system upgrade of the watch can be updating from one type of operating system to another type of operating system. Taking the current operating system of the watch as an example, the operating system of the watch can be updated from an Android system to a Harmony system. Alternatively, the operating system upgrade of the watch can also be updating from a first version to a second version of the same type of operating system. Optionally, the second version can be higher than the first version, taking the operating system of the watch as an example, i.e., upgrading from a low version of the Harmony system to a high version of the Harmony system. Alternatively, the second version can also be lower than the first version. For example, the operating system of the watch when it is shipped is a low version of the Harmony system, and the user can update the operating system of the watch to a high version of the Harmony system, and of course, if the user needs, it can also be restored to the low version of the Harmony system when it is shipped. For example, the watch provides an "factory reset" entry, through which the current high version of the operating system of the watch can be restored to the low version of the operating system when it is shipped. Optionally, the entry can also have other names, which are not limited in the embodiments of the present application. The entry can be located in the settings application in the watch, and of course, it can also be located in other positions.

[0103] (b), a theme updating scenario, i.e., updating a theme of the watch. The theme of the watch can be understood as a display template of the watch. Different display templates, i.e., different themes, can exhibit different display styles. Taking one theme as an example, if the theme is used, one or more interfaces in the watch need to be displayed according to a display style corresponding to the theme. The one or more interfaces can include a lock screen interface, a main interface, an application interface, a watch face, and the like. Optionally, the display style corresponding to each interface of the one or more interfaces can be the same or different. Taking the lock screen interface as an example, the lock screen interface is displayed according to the display style corresponding to the theme, which can include displaying display elements in the lock screen interface according to the display style corresponding to the theme. The display elements can include one or more of text, images, icons, symbols, numbers, and the like. For example, the wallpaper, time information, new messages, and the like in the lock screen interface are displayed according to the display style.

[0104] (c), a wallpaper updating scenario, i.e., updating a wallpaper of the watch. The wallpaper of the watch can include a wallpaper of one or more interfaces in the watch. The one or more interfaces can include a lock screen interface, a main interface, an application interface, and the like. Optionally, the wallpaper can be a static wallpaper or a dynamic wallpaper, which is not limited. In some embodiments, the theme updating and the wallpaper updating can be two independent processes without any association, for example, the theme is not updated when the theme is updated, and the theme is not affected when the wallpaper is updated. In this case, the user can update the theme or the wallpaper according to the needs. In other embodiments, the theme updating and the wallpaper updating can have a certain association, for example, the wallpaper is updated when the theme is updated, but the wallpaper is not affected when the wallpaper is updated. In this case, when the user updates the theme of the watch, the wallpaper changes synchronously. Of course, the user can not update the theme, but only update the wallpaper.

[0105] (d), an application upgrade scenario, i.e., upgrading an application in the watch. The application upgrade can include updating from a first version of the application to a second version. The application can be various types of applications, such as instant messaging applications, health and sports applications, image shooting applications, map applications, etc. The application can be a system-level application or a third-party application, without limitation. Optionally, the second version can be higher than the first version, i.e., upgrading from a low version to a high version of the application. Alternatively, the second version can also be lower than the first version, i.e., restoring the application from a high version to a low version. For example, the watch includes an application that is a low version, and the user can upgrade the application to a high version, and of course, if the user needs, the user can also restore the application from a high version to a low version. For example, the watch provides an "application initialization" entry through which the application can be restored from the current high version to a low version. It should be noted that the entry can also have other names, such as "factory reset", and the embodiments of the present application do not limit this. The entry can be located in the interface of the application, and of course, it can also be located in other locations.

[0106] (e), an offline map scenario, i.e., a scenario in which the watch is currently using an offline map. Since the memory of the watch is small, the watch can obtain the offline map from the phone when using the offline map. Therefore, the watch and the phone need to transmit files, i.e., offline maps, so a Wi-Fi connection needs to be established.

[0107] II. The format of the file to be transmitted is a preset format. For example, the preset format can include one or more of a video file format, an image file format, and a compressed package file format. The video file format can include mp3 format, mp4 format, wav format, etc. The image file format can include jpg format, png format, etc. The compressed package file format can include zip format, rar format, heif format, etc.

[0108] III. The file amount of the file to be transmitted is greater than a threshold value. For example, the threshold value can be 5M, 10M, 20M, 30M, etc., and the specific value is not limited by the embodiments of the present application.

[0109] It should be noted that the file transmission between the watch and the mobile phone can include two cases: 1. the watch transmits the file to the mobile phone; 2. the mobile phone transmits the file to the watch. In the two cases, the processing manner of the watch can be different. Taking the case 1 as an example, the watch needs to transmit the file to the mobile phone, so the to-be-transmitted file is located at the watch side, and the watch can determine whether the format of the to-be-transmitted file is the preset format and whether the file amount of the to-be-transmitted file is greater than the threshold. Taking the case 2 as an example, the mobile phone needs to transmit the file to the watch, so the to-be-transmitted file is located at the mobile phone side, in this case, the watch can inquire (for example, through Bluetooth inquiry) the format, file size and the like of the to-be-transmitted file from the mobile phone, and after determining the format and file size of the to-be-transmitted file, the watch can determine whether the format of the to-be-transmitted file is the preset format and whether the file amount of the to-be-transmitted file is greater than the threshold.

[0110] Four, the current running load of the watch is lower than the load threshold. Exemplarily, the current running load of the watch can be described by one or more of the CPU running load, the memory occupancy, the number of currently running applications and the like.

[0111] Five, the current remaining power of the watch is higher than the power threshold. Exemplarily, the power threshold can be 20%, 10%, 30% and the like, and the specific value is not limited by the embodiments of the application.

[0112] In some embodiments, the watch can further output first prompt information before creating the second Wi-Fi hotspot, the first prompt information being used to prompt the user to confirm whether to create the second Wi-Fi hotspot. If the watch receives a confirmation instruction, the second Wi-Fi hotspot is created.

[0113] S402, the watch broadcasts a signal, and the signal includes the name of the second Wi-Fi hotspot.

[0114] Optionally, the name of the second Wi-Fi hotspot can be the SSID of the second Wi-Fi hotspot. The name can be generated by the mobile phone itself or set by the user, and is not limited.

[0115] S403, the mobile phone searches for the second Wi-Fi hotspot.

[0116] It should be noted that after the mobile phone searches the second Wi-Fi hotspot of the watch, if the second Wi-Fi connection between the mobile phone and the watch is to be automatically established, the connection information of the second Wi-Fi hotspot needs to be known, and the connection information is used to connect to the second Wi-Fi hotspot. For example, the connection information of the second Wi-Fi hotspot can include a password of the second Wi-Fi hotspot, and optionally, the name of the second Wi-Fi hotspot. The password can be generated by the mobile phone itself or set by the user, and is not limited. In the embodiment of the present application, the mobile phone can receive the connection information of the second Wi-Fi hotspot from the watch through Bluetooth, that is, S404 and S405.

[0117] S404, the watch establishes a Bluetooth connection with the mobile phone.

[0118] Optionally, the execution sequence of S404 and S401-S403 is not limited, for example, S404 can be executed before S401.

[0119] S405, the watch sends the connection information of the second Wi-Fi hotspot to the mobile phone through Bluetooth.

[0120] S406, the mobile phone establishes a second Wi-Fi connection with the watch based on the connection information of the second Wi-Fi hotspot.

[0121] S407, the watch disconnects the Bluetooth connection between the watch and the mobile phone.

[0122] Optionally, S407 can be executed or not executed, so the dashed line is used in the figure. In addition, the execution sequence between S407 and S406 is not limited. It should be understood that the watch disconnects the Bluetooth connection between the watch and the mobile phone, which helps to save power consumption, and also avoids the interference of the Bluetooth signal to the Wi-Fi signal.

[0123] Figure 4B In the embodiment shown, after the watch creates the second Wi-Fi hotspot, the watch can provide the information of the second Wi-Fi hotspot (for example, the name and password of the second Wi-Fi hotspot) to the mobile phone. The mobile phone establishes a second Wi-Fi connection with the watch based on the information of the second Wi-Fi hotspot. In this way, no manual operation of the user is needed, the automatic establishment of the second Wi-Fi connection is realized, and the convenience is improved.

[0124] In the above embodiments, two implementations of the second scheme are illustrated. Since the second scheme is that the watch is the sender of the Wi-Fi hotspot, the watch can select to use one of the two implementations. There can be multiple selection methods. In method C, a display component is provided in the watch to facilitate the user to set an automatic connection mode or a manual connection mode. If the user sets the automatic connection mode, the automatic connection method is adopted; if the user sets the manual connection mode, the manual connection method is adopted. In method D, the watch can determine whether a Bluetooth connection has been established at present. If yes, the automatic connection method is adopted; otherwise, the manual connection method is adopted.

[0125] In the above embodiments, two schemes are provided, in which the roles of the watch are different. In the first scheme, the watch is the receiver of the Wi-Fi hotspot; in the second scheme, the watch is the sender of the Wi-Fi hotspot. In the embodiments of the present application, the watch can support only the first scheme, i.e., only as the receiver of the Wi-Fi hotspot; or only the second scheme, i.e., only as the sender of the Wi-Fi hotspot; or both the first scheme and the second scheme, i.e., the watch can be both the sender and the receiver of the Wi-Fi hotspot. Taking the watch supporting both the first scheme and the second scheme as an example, the watch can select to use one of the two schemes. For example, the watch can provide a selection interface for the user to select, and determine which scheme to use according to the user selection operation. For another example, the watch can also determine which scheme to use by itself, for example, the following three determination methods can be included.

[0126] In the first method, the watch determines whether the first Wi-Fi hotspot created by the mobile phone can be searched. If it is determined that the first Wi-Fi hotspot of the mobile phone cannot be searched, the second scheme is adopted; if the first Wi-Fi hotspot of the mobile phone can be searched, the first scheme is adopted. Optionally, in order to improve accuracy, when the watch determines whether the first Wi-Fi hotspot of the mobile phone can be searched, one or more searches can be performed. Taking multiple searches as an example, after the first search is performed, if the first search is not successful, the second search can be performed. Optionally, before the second search is performed, the watch can send (for example, through Bluetooth) a request information to the mobile phone to request the mobile phone to create the first Wi-Fi hotspot. After the request information is sent, the watch performs the second search. If the second search is also not successful, the next search or the search can be stopped.

[0127] The second mode is that the watch determines whether it can connect to the first Wi-Fi hotspot created by the mobile phone. If it is determined that the watch cannot connect to the first Wi-Fi hotspot of the mobile phone, the second mode is adopted. If the watch can connect to the first Wi-Fi hotspot of the mobile phone, the first mode is adopted. Optionally, the watch determines whether it can connect to the first Wi-Fi hotspot of the mobile phone, which can include that the watch sends a connection request to the mobile phone. The connection request is used to request to establish the first Wi-Fi connection. If a connection permission instruction of the mobile phone is received, it means that the watch can connect to the first Wi-Fi hotspot of the mobile phone. If no connection permission instruction of the mobile phone is received or a connection rejection instruction of the mobile phone is received, it means that the watch cannot connect to the first Wi-Fi hotspot of the mobile phone. One possible reason why the watch cannot connect to the first Wi-Fi hotspot of the mobile phone is that the operating system of the mobile phone is different from the operating system of the watch, and the operating system of the mobile phone limits the watch to establish a Wi-Fi connection with the mobile phone. Another possible reason is that the network quality is poor, which causes the watch to fail to connect to the first Wi-Fi hotspot of the mobile phone. Of course, there can be other reasons, which are not listed one by one. Regardless of the reason, as long as the watch determines that it cannot connect to the first Wi-Fi hotspot of the mobile phone, the second mode is adopted to ensure that the watch and the mobile phone can establish a Wi-Fi connection.

[0128] The third mode is that the watch determines whether the operating system of the mobile phone is a preset operating system. Taking the operating system of the watch as the Harmony operating system or the Android operating system as an example, the preset operating system can be the IOS system. If the watch determines that the operating system of the mobile phone is the preset operating system, the second mode is adopted. If the watch determines that the operating system of the mobile phone is not the preset operating system, the first mode is adopted. In this mode, the watch needs to determine the operating system of the mobile phone. One possible way is that the watch establishes a Bluetooth connection with the mobile phone, and the watch sends inquiry information to the mobile phone through the Bluetooth connection, to inquire about the operating system of the mobile phone. After receiving the inquiry information, the mobile phone returns an inquiry result to the watch. The inquiry result includes information of the operating system of the mobile phone, which can include the name and version of the operating system. Of course, the mobile phone can also actively send the information of the operating system to the watch. The watch determines the operating system of the mobile phone based on the information. After determining the operating system of the mobile phone, the watch can determine whether the operating system of the mobile phone is the preset operating system. One possible way is that the watch stores information of the preset operating system, which includes, for example, the name and version of the preset operating system. After receiving the information of the operating system of the mobile phone, the watch can match the received information with the locally stored information of the preset operating system. If they are consistent, it is determined that the operating system of the mobile phone is the preset operating system. If they are not consistent, it is determined that the operating system of the mobile phone is not the preset operating system. That is to say, in the embodiments of the present application, the watch serves as the sender of the Wi-Fi hotspot in the case where the operating system of the mobile phone is the preset operating system, to realize the Wi-Fi connection between the watch and the mobile phone.

[0129] It should be noted that the above lists three ways for the watch to determine whether to use the first scheme or the second scheme, and it should be understood that there can be other ways, and the embodiments of the present application do not list them one by one.

[0130] Taking the third way as an example, it is assumed that the watch determines that the first scheme needs to be used through the third way, that is, the watch is the receiver of the Wi-Fi hotspot. In this case, the watch needs to search for the first Wi-Fi hotspot of the mobile phone. One possible case is that the mobile phone has created the first Wi-Fi hotspot, so the watch can directly search for the first Wi-Fi hotspot of the mobile phone. Another possible case is that the mobile phone has not created the first Wi-Fi hotspot, in which case the watch cannot search for the first Wi-Fi hotspot of the mobile phone. In order to improve efficiency, the watch can request the mobile phone to create the first Wi-Fi hotspot, for example, the watch establishes a Bluetooth connection with the mobile phone, and sends a request message to the mobile phone through the Bluetooth connection to request the mobile phone to create the first Wi-Fi hotspot.

[0131] Taking the third way as an example, it is assumed that the watch determines that the second scheme needs to be used through the third way, that is, the watch is the sender of the Wi-Fi hotspot. In this case, the watch needs to create a second Wi-Fi hotspot so that the mobile phone can establish a second Wi-Fi connection with it. As described above, the second scheme includes two implementation ways, that is, manual connection and automatic connection. The watch can select to use one of the two implementation ways. There are many selection methods, for example, the above-mentioned way C or way D. Alternatively, in order to facilitate user operation, when the watch determines to use the manual connection way, a pop-up interface such as Figure 4A (a) can be popped up, which is used to create a second Wi-Fi hotspot.

[0132] In the above embodiments, the process of establishing a Wi-Fi connection between the watch and the mobile phone is mainly described. In some other embodiments, the watch and the mobile phone can not only support Wi-Fi connection, but also support other short-distance communication modes, for example, they can also support Bluetooth connection. In this case, the watch can select to establish a Bluetooth connection or a Wi-Fi connection with the mobile phone. Considering that the Wi-Fi connection has large power consumption and the Bluetooth connection has small power consumption, in order to avoid power waste, the watch and the mobile phone can default to use the Bluetooth connection, and establish a Wi-Fi connection in necessary cases (for example, the case where the fourth condition is met in the following).

[0133] For example, please refer to Figure 5 , which is another flowchart of the device connection method provided by an embodiment of the present application. The method can be applied to Figure 1 the communication system shown in the figure. As shown in Figure 5 , the flowchart can include:

[0134] S501, the watch establishes a Bluetooth connection with the mobile phone.

[0135] S502, the watch determines that the fourth condition is met.

[0136] Optionally, the fourth condition can include at least one of the following:

[0137] Condition one, the current service scenario of the watch is a preset scenario. Exemplarily, the preset scenario can include one of the following: a system upgrade scenario, a theme update scenario, a wallpaper update scenario, an application upgrade scenario, and an offline map scenario. For the preset scenario, please refer to the foregoing description. It should be understood that, in the case that the current service scenario of the watch is a preset scenario, it means that there is a file transmission demand between the watch and the mobile phone and it is very likely to transmit a file with a large amount of data, so the watch and the mobile phone need to establish a Wi-Fi connection to improve the transmission rate.

[0138] Condition two, the format of the file to be transmitted is a preset format. Exemplarily, the preset format can include one or more of the following: a video file format, an image file format, and a compressed package file format. The video file format can include mp3 format, mp4 format, wav format, etc. The image file format can include jpg format, png format, etc. The compressed package file format can include zip format, rar format, heif format, etc.

[0139] Condition three, the file amount of the file to be transmitted is greater than a threshold value. Exemplarily, the threshold value can be 5M, 10M, 20M, 30M, etc., and the specific value is not limited in the embodiments of the present application.

[0140] It should be noted that the above three conditions are only examples, and other conditions can also be included, which are not listed one by one.

[0141] S503, the watch establishes a Wi-Fi connection with the mobile phone.

[0142] As described above, the watch and the mobile phone establishing a Wi-Fi connection can include two schemes, i.e., the first scheme (the mobile phone as the sender of the Wi-Fi hotspot) and the second scheme (the watch as the sender of the Wi-Fi hotspot) described above. The watch can select to use one of the two schemes, and the specific selection manner is described in detail above, which is not repeated here.

[0143] S504, the watch disconnects the Bluetooth connection between the watch and the mobile phone.

[0144] Optionally, S504 can be executed or not executed, so the dashed line is used in the figure. Optionally, the execution order of S504 and S503 is not limited.

[0145] Please refer to Figure 6This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application. The electronic device can be the first device (e.g., a mobile phone) or the second device (e.g., a watch) mentioned above. Figure 6 As shown, the electronic device may include a processor 110, an external memory interface 120, an internal memory 121, a universal serial bus (USB) interface 130, a charging management module 140, a power management module 141, a battery 142, an antenna 1, an antenna 2, a mobile communication module 150, a wireless communication module 160, an audio module 170, a speaker 170A, a receiver 170B, a microphone 170C, a headphone jack 170D, a sensor module 180, buttons 190, a motor 191, an indicator 192, a camera 193, a display screen 194, and a subscriber identification module (SIM) card interface 195, etc. The sensor module 180 may include a pressure sensor 180A, a gyroscope sensor 180B, a barometric pressure sensor 180C, a magnetic sensor 180D, an accelerometer sensor 180E, a distance sensor 180F, a proximity sensor 180G, a fingerprint sensor 180H, a temperature sensor 180J, a touch sensor 180K, an ambient light sensor 180L, a bone conduction sensor 180M, etc.

[0146] The processor 110 can include one or more processing units, for example: the processor 110 can include an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a memory, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural-network processing unit (NPU), etc. Different processing units can be independent devices or integrated in one or more processors. The controller can be the nerve center and command center of the electronic device. The controller can generate operation control signals according to instruction operation codes and timing signals, and complete the control of fetching and executing instructions. A memory can also be provided in the processor 110 for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory can save instructions or data that the processor 110 has just used or repeatedly uses. If the processor 110 needs to use the instructions or data again, it can directly call from the memory. This avoids repeated access and reduces the waiting time of the processor 110, thereby improving the efficiency of the system.

[0147] In some embodiments, the processor 110 can perform the device connection method provided by the embodiments of the present application. Taking the electronic device as a watch as an example, the processor 110 can create a second Wi-Fi hotspot and send information of the second Wi-Fi hotspot to the mobile phone, so that the mobile phone establishes a second Wi-Fi connection with the watch based on the information of the second Wi-Fi hotspot.
