Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to a method for outputting a pairing notification and related equipment. Background Art

[0002] In order to facilitate pairing and connection, pairing and connection can be completed based on proximity discovery technology. Specifically, the Bluetooth peripheral can send a proximity discovery message. When the terminal device scans the proximity discovery message sent by the Bluetooth peripheral, the physical distance between the Bluetooth peripheral and the terminal device can be determined based on the proximity discovery message. When the terminal device determines that the physical distance between the Bluetooth peripheral and the terminal device is within the first range, the terminal device finds that the Bluetooth peripheral is nearby and can output a pairing notification to pair with the Bluetooth peripheral and establish a Bluetooth connection.

[0003] However, with the continuous expansion of Bluetooth communication application scenarios, Bluetooth attacks are becoming more and more common. For example, after knowing the format of the proximity discovery message, a malicious attacker can send a forged proximity discovery message at maximum power, causing terminal devices in a large range to output pairing notifications. These pairing notifications will cause harassment to users and affect their experience. Therefore, how to prevent terminal devices in a large range from outputting pairing notifications is an urgent problem to be solved. Summary of the invention

[0004] The embodiments of the present application provide a method for outputting a pairing notification and related devices, which can output a pairing notification on a first terminal device with the shortest first distance from a Bluetooth peripheral, and not output the pairing notification on other terminal devices, thereby effectively avoiding that terminal devices within a large range all output the pairing notification.

[0005] In a first aspect, an embodiment of the present application provides a method for outputting a pairing notification, the method comprising:

[0006] Determine the first distance between the first terminal device and the Bluetooth peripheral device and the first distance between other terminal devices and the Bluetooth peripheral device, and based on the first distances between the terminal device and the other terminal devices and the Bluetooth peripheral device, determine whether the first distance between the first terminal device and the Bluetooth peripheral device is smaller than the first distance between the other terminal devices and the Bluetooth peripheral device. If so, output a pairing notification on the first terminal device; wherein the pairing notification is used to notify that the first terminal device is allowed to establish a Bluetooth pairing with the Bluetooth peripheral device. The other terminal devices are terminal devices other than the first terminal device whose physical distance to the Bluetooth peripheral device is within the first range; the first distance between each terminal device and the Bluetooth peripheral device is related to the physical distance between the terminal device and the Bluetooth peripheral device.

[0007] It can be seen that for the first terminal device and other terminal devices whose physical distance to the Bluetooth peripheral is within the first range, unlike the technical solution of outputting pairing notifications on both the first terminal device and the other terminal devices, the embodiment of the present application only outputs pairing notifications on the first terminal device whose first distance to the Bluetooth peripheral is the smallest, and does not output pairing notifications on other terminal devices, which can effectively avoid outputting pairing notifications on terminal devices within a large range.

[0008] In addition, since the pairing notification is only output on the first terminal device with the shortest first distance between it and the Bluetooth peripheral, the probability of the terminal device establishing a Bluetooth connection with the Bluetooth peripheral is reduced, thereby reducing the probability of data leakage via the Bluetooth connection (such as reducing the probability of leakage of personal privacy data such as user call records and text message records), which can effectively ensure data security.

[0009] In combination with the first aspect, in an optional implementation, the first distance between each terminal device and the Bluetooth peripheral is equal to the product of the physical distance between the terminal device and the Bluetooth peripheral and the penalty factor of the terminal device; the penalty factor of each terminal device is related to at least one parameter of the terminal device's screen status, running applications, AR status, RSSI of proximity discovery messages, or transmission power of proximity discovery messages.

[0010] It can be seen that in this embodiment, the first distance between the terminal device and the Bluetooth peripheral is not only related to the physical distance between the terminal device and the Bluetooth peripheral, but also to at least one parameter of the terminal device's screen state, running application, AR state, RSSI of the proximity discovery message, or the transmission power of the proximity discovery message. Since at least one parameter of the terminal device characterizes the scene in which the user currently uses the terminal device, the penalty factor of the terminal device determined based on at least one parameter of the terminal device can characterize the degree of pairing demand between the user and the Bluetooth peripheral (such as when the penalty factor is large, the degree of pairing demand between the user and the Bluetooth peripheral is low; when the penalty factor is small, the degree of pairing demand between the user and the Bluetooth peripheral is high), then the first distance determined based on the penalty factor of the terminal device also characterizes the degree of pairing demand between the user and the Bluetooth peripheral. When the pairing notification is output on the terminal device with the smallest first distance to the Bluetooth peripheral, it is beneficial for the Bluetooth peripheral to establish a connection with the terminal device of the user with a high degree of pairing demand.

[0011] In conjunction with the first aspect, in an optional implementation, the first distance between each terminal device and the Bluetooth peripheral is equal to the physical distance between the terminal device and the Bluetooth peripheral. It can be seen that in this implementation, the calculation method of the first distance between the terminal device and the Bluetooth peripheral is relatively simple, which can effectively save computing resources.

[0012] In combination with the first aspect, in an optional implementation manner, the method further includes:

[0013] Receiving first information from other terminal devices;

[0014] The first information of each terminal device in other terminal devices includes the physical distance between the terminal device and the Bluetooth peripheral device; or,

[0015] The first information of each terminal device in the other terminal devices includes at least one parameter of the screen state, running application, AR state, RSSI of the proximity discovery message, and transmission power of the proximity discovery message of the terminal device, and the physical distance between the terminal device and the Bluetooth peripheral device. It can be seen that in this embodiment, the first information of the other terminal devices can be received, which is conducive to determining the first distance between the other terminal devices and the Bluetooth peripheral device based on the first information of the other terminal devices.

[0016] In combination with the first aspect, in an optional implementation manner, the method further includes:

[0017] For each parameter of each terminal device, determine whether the parameter of the terminal device meets the condition corresponding to the parameter; if so, determine the penalty factor of the parameter of the terminal device;

[0018] For each terminal device, the penalty factor of each parameter of the terminal device is added together to obtain the penalty factor of the terminal device.

[0019] In combination with the first aspect, in an optional implementation, the method further includes: broadcasting first information of the first terminal device.

[0020] Optionally, this implementation can be performed by the first terminal device. It can be seen that in this implementation, the first terminal device can broadcast its own first information, so as to facilitate the management device or other terminal devices to receive the first information of the first terminal device and determine the first distance between the first terminal device and the Bluetooth peripheral device based on the first information.

[0021] In combination with the first aspect, in an optional implementation, if the first distance between the first terminal device and the Bluetooth peripheral is smaller than the first distance between other terminal devices and the Bluetooth peripheral, the method further includes: determining whether the first distance between the first terminal device and the Bluetooth peripheral is within the second range; if so, executing the step of outputting a pairing notification on the first terminal device. It can be seen that in this implementation, the first distance between the first terminal device and the Bluetooth peripheral can be further compared with the second range, which is conducive to outputting a pairing notification only when the first distance is within the second range, and not outputting a pairing notification when the first distance is outside the second range, further reducing the probability of the terminal device and the Bluetooth peripheral establishing a Bluetooth connection, thereby further reducing the probability of data leakage via the Bluetooth connection, and further ensuring the security of the data.

[0022] In combination with the first aspect, in an optional implementation manner, the method further includes:

[0023] receiving proximity discovery messages;

[0024] In response to the proximity discovery message, a step of determining a first distance between the first terminal device and the Bluetooth peripheral device and a first distance between other terminal devices and the Bluetooth peripheral device is performed.

[0025] In conjunction with the first aspect, in an optional implementation manner, the method further includes:

[0026] If there are other terminal devices whose first distance to the Bluetooth peripheral is smaller than the first distance between the first terminal device and the Bluetooth peripheral, or the first distance between the first terminal device and the Bluetooth peripheral is outside the second range, the first terminal device is triggered to discard the proximity discovery message.

[0027] In a second aspect, an embodiment of the present application provides an electronic device, including a touch screen, a memory, one or more processors, and one or more programs; wherein the one or more programs are stored in the memory, and characterized in that when the one or more processors execute the one or more programs, the electronic device implements: determining the first distance between the first terminal device and the Bluetooth peripheral device and the first distance between other terminal devices and the Bluetooth peripheral device, and based on the first distance between the terminal device and the other terminal devices and the Bluetooth peripheral device, determining whether the first distance between the first terminal device and the Bluetooth peripheral device is smaller than the first distance between the other terminal devices and the Bluetooth peripheral device, if so, outputting a pairing notification on the first terminal device; wherein the pairing notification is used to notify that the first terminal device is allowed to establish a Bluetooth pairing with the Bluetooth peripheral device. The other terminal devices are terminal devices other than the first terminal device whose physical distance with the Bluetooth peripheral device is within the first range; the first distance between each terminal device and the Bluetooth peripheral device is related to the physical distance between the terminal device and the Bluetooth peripheral device.

[0028] In combination with the second aspect, in an optional implementation, the first distance between each terminal device and the Bluetooth peripheral is equal to the product of the physical distance between the terminal device and the Bluetooth peripheral and the penalty factor of the terminal device; the penalty factor of each terminal device is related to at least one parameter of the terminal device's screen status, running applications, AR status, RSSI of proximity discovery messages, or transmission power of proximity discovery messages.

[0029] In combination with the second aspect, in an optional implementation, the first distance between each terminal device and the Bluetooth peripheral device is equal to the physical distance between the terminal device and the Bluetooth peripheral device.

[0030] In conjunction with the second aspect, in an optional implementation manner, the electronic device is further used for:

[0031] Receiving first information from other terminal devices;

[0032] The first information of each terminal device in other terminal devices includes the physical distance between the terminal device and the Bluetooth peripheral device; or,

[0033] The first information of each terminal device among the other terminal devices includes at least one parameter of the screen status, running applications, AR status, RSSI of the proximity discovery message, transmission power of the proximity discovery message, and the physical distance between the terminal device and the Bluetooth peripheral.

[0034] In conjunction with the second aspect, in an optional implementation manner, the electronic device is further used for:

[0035] For each parameter of each terminal device, determine whether the parameter of the terminal device meets the condition corresponding to the parameter; if so, determine the penalty factor of the parameter of the terminal device;

[0036] For each terminal device, the penalty factor of each parameter of the terminal device is added together to obtain the penalty factor of the terminal device.

[0037] In combination with the second aspect, in an optional implementation, the electronic device is also used to: broadcast the first information of the first terminal device.

[0038] In conjunction with the second aspect, in an optional implementation, if the first distance between the first terminal device and the Bluetooth peripheral device is smaller than the first distance between other terminal devices and the Bluetooth peripheral device, the electronic device is further used to: determine whether the first distance between the first terminal device and the Bluetooth peripheral device is within a second range;

[0039] If yes, the step of outputting a pairing notification on the first terminal device is performed.

[0040] In conjunction with the second aspect, in an optional implementation manner, the electronic device is further used to: receive a proximity discovery message;

[0041] In response to the proximity discovery message, a step of determining a first distance between the first terminal device and the Bluetooth peripheral device and a first distance between other terminal devices and the Bluetooth peripheral device is performed.

[0042] In combination with the second aspect, in an optional implementation, the electronic device is also used to: trigger the first terminal device to discard the proximity discovery message if there are other terminal devices whose first distance to the Bluetooth peripheral is smaller than the first distance between the first terminal device and the Bluetooth peripheral, or the first distance between the first terminal device and the Bluetooth peripheral is outside the second range.

[0043] In this aspect, the beneficial effects of the above-mentioned various optional implementations can refer to the beneficial effects of the first aspect and related implementations, and will not be repeated here.

[0057] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0058] 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 this article is only a description of the association relationship of 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. In addition, in the description of the embodiments of the present application, "at least one" means one or more items.

[0059] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating 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. In the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

[0060] It should be pointed out that the "equal to" involved in the embodiments of the present application can be used in conjunction with "greater than", and is applicable to the technical solution adopted when "greater than" is used, and can also be used in conjunction with "less than", and is applicable to the technical solution adopted when "less than" is used. It should be noted that when "equal to" is used in conjunction with "greater than", it cannot be used in conjunction with "less than"; when "equal to" is used in conjunction with "less than", it cannot be used in conjunction with "greater than".

[0061] In order to solve the problem of pairing and connecting Bluetooth peripherals with terminal devices, the prior art proposes a method for pairing and connecting based on proximity discovery messages (which can be BLE broadcast messages). Optionally, the physical distance between the terminal device and the Bluetooth peripheral can be achieved through RSSI ranging. The physical distance between the terminal device and the Bluetooth peripheral is inversely proportional to the RSSI. The larger the RSSI, the smaller the physical distance between the terminal device and the Bluetooth peripheral; the smaller the RSSI, the larger the physical distance between the terminal device and the Bluetooth peripheral. For example, the correspondence between the physical distance between the terminal device and the Bluetooth peripheral and the RSSI can be expressed as:

[0062]

[0063] Wherein, r is the physical distance between the terminal device and the Bluetooth peripheral device, A is the preset signal strength when the Bluetooth peripheral device is 1 meter away from the terminal device, and n is the preset environmental attenuation factor.

[0064] like Figure 1 As shown, a schematic diagram of a process for establishing a pairing connection is shown. The Bluetooth peripheral can send a proximity discovery message. When the terminal device scans (receives) the proximity discovery message, the terminal device performs a received signal strength indication (RSSI) ranging based on the proximity discovery message, and determines the physical distance between the terminal device itself and the Bluetooth peripheral based on the RSSI ranging result. The terminal device can determine whether the physical distance between itself and the Bluetooth peripheral is within the first range. If so, a pairing notification is output so that the terminal device can be paired with the Bluetooth peripheral and establish a Bluetooth connection.

[0065] For example, Figure 2 This is a schematic diagram of an interface of a terminal device. Figure 2 As shown, the Bluetooth peripheral 201 can send a proximity discovery message. When the terminal device 202 scans (or receives) the proximity discovery message sent by the Bluetooth peripheral 201, it can determine the physical distance between the Bluetooth peripheral 201 and the terminal device 202 based on the proximity discovery message. When the terminal device 202 determines that the physical distance between the Bluetooth peripheral 201 and the terminal device 202 is within the first range, the pairing notification 202-1 can be displayed on the interface. The pairing notification 202-1 is used to notify that the Bluetooth peripheral 201 is allowed to establish a Bluetooth pairing with the terminal device 202. For example, the pairing notification 202-1 displays the Bluetooth peripheral logo 202-2 ( Figure 2Taking the icon of a Bluetooth peripheral as an example, the identifier 202-2 may also be the model of the Bluetooth peripheral), as well as an "Allow" control 202-3 and a "Reject" control 202-4. A user clicking the "Allow" control 202-3 may trigger the Bluetooth peripheral 201 to pair with the terminal device 202 and establish a Bluetooth connection. A user clicking the "Reject" control 202-4 may trigger the terminal device to delete the pairing notification. It should be noted that the pairing notification shown in the embodiment of the present application is only for illustrative purposes, and the pairing notification may also be in other forms, for example, the pairing notification may also be a voice notification, without limitation.

[0066] With the continuous expansion of Bluetooth communication application scenarios, Bluetooth attack incidents are becoming more and more common. For example, after knowing the format of the proximity discovery message, a malicious attacker can send a forged proximity discovery message at the maximum transmission power, causing terminal devices within a large range to output pairing notifications. These pairing notifications will cause harassment to users and affect the user experience. It should be noted that a forged proximity discovery message may refer to a proximity discovery message whose actual transmission power is greater than the reported transmission power. Optionally, the proximity discovery message may carry a "tx power" field, and the "tx power" field is used to report the transmission power of the proximity discovery message. Therefore, how to prevent terminal devices within a large range from outputting pairing notifications is an urgent problem to be solved.

[0067] The embodiment of the present application proposes a method for outputting a pairing notification and related devices. In this method, based on the first distances between the first terminal device and the other terminal devices and the Bluetooth peripheral respectively, it can be determined whether the first distance between the first terminal device and the Bluetooth peripheral is less than the first distance between the other terminal devices and the Bluetooth peripheral; if so, a pairing notification is output on the first terminal device. Among them, the other terminal devices are terminal devices other than the first terminal device whose physical distances to the Bluetooth peripheral are within the first range; the first distance between each terminal device and the Bluetooth peripheral is related to the physical distance between the terminal device and the Bluetooth peripheral. Different from the technical solution of outputting pairing notifications on both the first terminal device and the other terminal devices, the technical solution of the embodiment of the present application only outputs pairing notifications on the first terminal device whose first distance to the Bluetooth peripheral is the smallest, which can effectively avoid outputting pairing notifications on terminal devices within a large range.

[0068] Combine the following Figure 3A The scene diagram and Figure 3B The scenario diagrams described above elaborate on the differences between the embodiments of the present application and the existing solutions. Figure 3A A schematic diagram of a scenario provided by the prior art is shown. Figure 3B A schematic diagram of a scenario provided by an embodiment of the present application is shown. Figure 3A and Figure 3BThe communication system in the scenario shown may include a Bluetooth peripheral 301 and multiple terminal devices (such as multiple terminal devices including a first terminal device 302 and other terminal devices 303). Among them, the physical distance between the first terminal device 302 and the Bluetooth peripheral 301 is within the first range, and the physical distance between the other terminal devices 303 and the Bluetooth peripheral 301 is also within the first range. It should be noted that the first terminal device and the other terminal devices are only used to represent different terminal devices. In other scenarios, the other terminal devices 303 can also be replaced by "second terminal device", "third terminal device", etc., without limitation. It should be noted that in other implementations, the other terminal devices may also include two, three or more terminal devices, without limitation.

[0069] like Figure 3A As shown, when the physical distance between the first terminal device 302 and the Bluetooth peripheral device 301 is within the first range, and the physical distance between the other terminal devices 303 and the Bluetooth peripheral device 301 is also within the first range, if the existing technical solution is implemented, the pairing notification 300 can be output on the first terminal device 302 and the other terminal devices 303. That is to say, when the Bluetooth peripheral device 301 as a malicious attacker sends a proximity discovery message at the maximum transmission power, the physical distances between multiple terminal devices and the Bluetooth peripheral device 301 are all within the first range, and multiple terminal devices all output pairing notifications. When the number of other terminal devices is large, the terminal devices within a large range all output pairing notifications.

[0070] like Figure 3B As shown, when the physical distance between the first terminal device 302 and the Bluetooth peripheral device 301 is within the first range, and the physical distance between the other terminal devices 303 and the Bluetooth peripheral device 301 is also within the first range, if the embodiment of the present application is implemented, the first distance between the first terminal device 302 and the Bluetooth peripheral device 301 can be determined based on the physical distance between the first terminal device 302 and the Bluetooth peripheral device 301, and the first distance between the other terminal devices 303 and the Bluetooth peripheral device 301 can be determined based on the physical distance between the other terminal devices 303 and the Bluetooth peripheral device 301. Then, it is determined whether the first distance between the first terminal device 302 and the Bluetooth peripheral device 301 is less than the first distance between the other terminal devices 303 and the Bluetooth peripheral device 301; if so, a pairing notification is output on the first terminal device 302. That is to say, when the Bluetooth peripheral 301 acting as a malicious attacker sends a proximity discovery message at the maximum transmission power, when the physical distances between multiple terminal devices and the Bluetooth peripheral 301 are all within the first range, the pairing notification is only output on the first terminal device 302 which has the shortest first distance to the Bluetooth peripheral 301, which can effectively avoid the output of pairing notifications by terminal devices within a large range.

[0071] Optionally, the embodiment of the present application may be executed by a device in the communication system (such as a first terminal device or other terminal devices, etc.), or by a management device outside the communication system. The management device is used to manage the communication system. It should be noted that when the embodiment of the present application is executed by a management device, the management device and the devices in the communication system can communicate with each other. For ease of explanation, "devices in the communication system" and "management devices" may be collectively referred to as "electronic devices".

[0072] Optionally, the Bluetooth peripherals described in the embodiments of the present application are not limited to Bluetooth headsets, mobile phones, Bluetooth mice, tablet computers, laptop computers, desktop computers, display screens, Bluetooth keyboards, Bluetooth printers, Bluetooth fax machines, Internet of Vehicles devices, etc.

[0073] Optionally, the terminal device described in the embodiment of the present application may include but is not limited to portable electronic devices such as mobile phones, tablet computers, personal digital assistants (PDAs), wearable devices, etc. Exemplary embodiments of portable electronic devices include but are not limited to portable electronic devices equipped with iOS, Android, Microsoft or other operating systems. The above-mentioned portable electronic devices may also be other portable electronic devices, such as laptop computers (laptops) with touch-sensitive surfaces (e.g., touch panels). It should also be understood that in some other embodiments of the present application, the terminal device may not be a portable electronic device, but a desktop computer with a touch-sensitive surface (e.g., a touch panel). The terminal device may include a first terminal device or other terminal devices.

[0074] Optionally, the management device described in the embodiment of the present application may be a terminal device or a server. The server may be a single server or a combination of multiple servers. The server may be an independent physical server or a server cluster or distributed system composed of multiple physical servers. It may also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, content delivery networks (CDN), middleware services, domain name services, security services, and big data and artificial intelligence platforms, etc.

[0075] The method for outputting pairing notification provided by an embodiment of the present application is described below with reference to the accompanying drawings.

[0076] See also Figure 4 , Figure 4 1 is a flow chart of a method for outputting a pairing notification provided by an embodiment of the present application. The method may be executed by a first terminal device or a management device. Figure 4As shown, the method of outputting the pairing notification includes but is not limited to S401-S403:

[0077] S401: Determine a first distance between a first terminal device and a Bluetooth peripheral device and a first distance between other terminal devices and the Bluetooth peripheral device.

[0078] It should be noted that for the sake of convenience, the "first terminal device" and the "other terminal devices" may be collectively referred to as terminal devices.

[0079] Among them, the physical distance between each terminal device and the Bluetooth peripheral device is within the first range. That is to say, the first terminal device is a terminal device whose physical distance with the Bluetooth peripheral device is within the first range, and other terminal devices are terminal devices other than the first terminal device whose physical distance with the Bluetooth peripheral device is within the first range. It should be noted that the first range can be any distance interval, for example, the first range is a distance interval of 0 cm to 20 cm, a distance interval of 20 cm to 50 cm, etc., without limitation.

[0080] The first distance between each terminal device and the Bluetooth peripheral device is related to the physical distance between the terminal device and the Bluetooth peripheral device. This will be described in detail in conjunction with Implementation 1.1 and Implementation 1.2.

[0081] Implementation 1.1: The first distance between each terminal device and the Bluetooth peripheral device is equal to the physical distance between the terminal device and the Bluetooth peripheral device. In other words, determining the first distance between each terminal device and the Bluetooth peripheral device includes: using the physical distance between each terminal device and the Bluetooth peripheral device as the first distance between each terminal device and the Bluetooth peripheral device.

[0082] Implementation 1.2: The first distance between each terminal device and the Bluetooth peripheral is equal to the product of the physical distance between the terminal device and the Bluetooth peripheral and the penalty factor of the terminal device. The penalty factor of each terminal device is related to at least one parameter of the screen state, running application, AR state, RSSI of the proximity discovery message, or the transmission power of the proximity discovery message of the terminal device. That is to say, determining the first distance between each terminal device and the Bluetooth peripheral includes: s11, determining the penalty factor of each terminal device based on at least one parameter of the screen state, running application, AR state, RSSI of the proximity discovery message, or the transmission power of the proximity discovery message of each terminal device; s12, multiplying the physical distance between each terminal device and the Bluetooth peripheral by the penalty factor of each terminal device to obtain the first distance between each terminal device and the Bluetooth peripheral.

[0083] S402: Based on the first distances between the first terminal device and the other terminal devices and the Bluetooth peripheral device respectively, determine whether the first distance between the first terminal device and the Bluetooth peripheral device is smaller than the first distances between the other terminal devices and the Bluetooth peripheral device.

[0084] In an optional implementation, step S402 specifically includes: comparing the first distance between the first terminal device and the Bluetooth peripheral device with the first distances between other terminal devices and the Bluetooth peripheral device, and determining whether the first distance between the first terminal device and the Bluetooth peripheral device is smaller than the first distances between the other terminal devices and the Bluetooth peripheral device. Figure 3B Taking the communication system shown as an example, the first distance between the first terminal device 302 and the Bluetooth peripheral device 301 can be compared with the first distance between the other terminal devices 303 and the Bluetooth peripheral device 301 to determine whether the first distance between the first terminal device 302 and the Bluetooth peripheral device 301 is smaller than the first distance between the other terminal devices 303 and the Bluetooth peripheral device 301. For another example, if there are multiple other terminal devices 303 (for example, the other terminal devices 303 specifically include other terminal devices 303-1 and other terminal devices 303-2), the first distance between the first terminal device 302 and the Bluetooth peripheral device 301 can be compared with the first distance between the other terminal device 303-1 and the Bluetooth peripheral device 301, and the first distance between the other terminal device 303-2 and the Bluetooth peripheral device 301 to determine whether the first distance between the first terminal device 302 and the Bluetooth peripheral device 301 is smaller than the first distance between the other terminal device 303-1 and the Bluetooth peripheral device 301, and smaller than the first distance between the other terminal device 303-2 and the Bluetooth peripheral device 301.

[0085] S403: If yes, a pairing notification is output on the first terminal device; the pairing notification is used to notify that the first terminal device is allowed to establish a Bluetooth pairing with the Bluetooth peripheral device.

[0086] In an optional implementation manner, if the solution of the present application is executed by a first terminal device, a pairing notification is output on the first terminal device, including: the first terminal device directly outputs the pairing notification.

[0087] In another optional implementation, if the solution of the present application is executed by a management device, outputting a pairing notification on the first terminal device includes: the management device sends a first instruction to the first terminal device, the first instruction is used to instruct the first terminal device to output a pairing notification. When the first terminal device receives the first instruction, the first terminal device outputs a pairing notification.

[0088] Optionally, the first terminal device outputs a pairing notification, including: the first terminal device calls a specific module (such as a nearby module and / or an iconnect module) to output a pairing notification.

[0089] Optionally, the first terminal device may output a pairing notification once within a screen-on / off cycle, so as to avoid the first terminal device repeatedly outputting the same or different pairing notifications within a screen-on / off cycle, thereby avoiding harassment to the user and improving the user experience.

[0090] In the embodiment of the present application, for the first terminal device and other terminal devices whose physical distances to the Bluetooth peripheral are within the first range, the electronic device can determine the first distance between the first terminal device and the Bluetooth peripheral, and the first distance between the other terminal devices and the Bluetooth peripheral, and when the first distance between the first terminal device and the Bluetooth peripheral is less than the first distance between the other terminal devices and the Bluetooth peripheral, a pairing notification can be output on the first terminal device. It can be seen that, unlike the technical solution of outputting pairing notifications on both the first terminal device and the other terminal devices, the embodiment of the present application only outputs pairing notifications on the first terminal device whose first distance to the Bluetooth peripheral is the smallest, which can effectively avoid outputting pairing notifications on terminal devices within a large range.

[0091] In addition, since the pairing notification is only output on the first terminal device with the shortest first distance between it and the Bluetooth peripheral, the probability of the terminal device establishing a Bluetooth connection with the Bluetooth peripheral is reduced, thereby reducing the probability of data leakage via the Bluetooth connection (such as reducing the probability of leakage of personal privacy data such as user call records and text message records), which can effectively ensure data security.

[0092] See also Figure 5 , Figure 5 It is a flowchart of another method for outputting pairing notification provided in an embodiment of the present application. Figure 5 The method described Figure 4 Compared with the method described above, Figure 5 The method described is described by taking the first terminal device executing the solution of the embodiment of the present application as an example. Figure 5 As shown, the method includes but is not limited to:

[0093] S501: The first terminal device determines a first distance between the first terminal device and the Bluetooth peripheral device.

[0094] Based on implementation 1.1, step S501 specifically includes: taking the physical distance between the first terminal device and the Bluetooth peripheral device as the first distance between the first terminal device and the Bluetooth peripheral device. It can be seen that in this implementation, the calculation method of the first distance between the terminal device and the Bluetooth peripheral device is relatively simple, which can effectively save computing resources.

[0095] Based on implementation 1.2, step S501 specifically includes: the first terminal device determines the penalty factor of the first terminal device based on at least one parameter of the screen status, running application, AR status, RSSI of the proximity discovery message, or transmission power of the proximity discovery message of the first terminal device; and multiplies the physical distance between the first terminal device and the Bluetooth peripheral device by the penalty factor of the first terminal device to obtain the first distance between the first terminal device and the Bluetooth peripheral.

[0096] In an optional implementation, the first terminal device determines the penalty factor of the first terminal device based on at least one parameter of the first terminal device's screen state, running applications, AR state, RSSI of proximity discovery messages, or transmission power of proximity discovery messages, including: for each parameter of the first terminal device, determining whether the parameter of the first terminal device meets the condition corresponding to the parameter; if so, determining the penalty factor of the parameter of the first terminal device, and adding the penalty factors of each parameter of the first terminal device to obtain the penalty factor of the first terminal device.

[0097] The following is a detailed description of the conditions corresponding to each parameter in conjunction with Table 1, as well as the penalty factor corresponding to the parameter when the condition is met. As shown in Table 1, when the parameter of the first terminal device is "screen status", the condition corresponding to the "screen status" is "whether it is in the screen off state", and the penalty factor corresponding to the "screen status" is "1"; when the parameter of the first terminal device is "running application", the condition corresponding to the "running application" is "whether it is a first type of application (such as a game application, a live broadcast application, etc.)", and the penalty factor corresponding to the "running application" is "1"; when the parameter of the first terminal device is "AR status", the condition corresponding to the "AR status" is "whether it is a non-stationary state or a non-micro-motion state (such as cycling, running) , driving, etc.)", the penalty factor corresponding to the AR state is "1"; when the parameter of the first terminal device is "RSSI of proximity discovery message", the condition corresponding to the "RSSI of proximity discovery message" is "whether it is a non-normal distribution", and the penalty factor corresponding to the RSSI of proximity discovery message is "1"; when the parameter of the first terminal device is "transmit power of proximity discovery message", the condition corresponding to the "transmit power of proximity discovery message" is "whether it is greater than the first value (such as 20 decibels)", and the penalty factor corresponding to the "transmit power of proximity discovery message" is "1". It should be noted that the parameters shown in the embodiments of the present application are only for exemplary purposes. In other embodiments, the parameters of the terminal device may also be other parameters, such as paired devices of the terminal device, etc., without limitation.

[0098] Table 1

[0099]

[0100] For example, taking the case where the screen state of the first terminal device is "screen off state", the running application is "music playback application", and the AR state is "non-static state", the penalty factor of the first terminal device may be "2".

[0101] For another example, taking the case where the screen state of the first terminal device is "on screen state", the running application is "game application", the AR state is "stationary state", the RSSI of the proximity discovery message is non-normally distributed, and the sending power of the proximity discovery message is greater than the first value, the penalty factor of the first terminal device may be "3".

[0102] The following example takes at least one parameter including the screen status of the terminal device, the running application, the AR status, the RSSI of the proximity discovery message, and the transmission power of the proximity discovery message as an example. Figure 6 Detailed description of the relevant embodiments for calculating the penalty factor of the terminal device, Figure 6 1 is a flow chart of calculating a penalty factor of a terminal device provided in an embodiment of the present application. Figure 6 The following may include but are not limited to:

[0103] S61: Set the initial value P of the penalty factor of the terminal device to 0.

[0104] S62: Obtain the screen status, running applications, AR status, RSSI of the proximity discovery message, and the transmission power of the proximity discovery message of the terminal device.

[0105] S63: Determine whether the screen status of the terminal device is off. If so, update the penalty factor of the terminal device, that is, P=P+1; otherwise, keep the penalty factor of the terminal device unchanged, that is, P=P.

[0106] S64: Determine whether the running application of the terminal device is a first type application. If so, update the penalty factor of the terminal device, that is, P=P+1; otherwise, keep the penalty factor of the terminal device unchanged, that is, P=P.

[0107] S65: Determine whether the AR state of the terminal device is a non-static state or a non-micro-motion state. If so, update the penalty factor of the terminal device, that is, P=P+1; otherwise, keep the penalty factor of the terminal device unchanged, that is, P=P.

[0108] S66: Determine whether the RSSI of the proximity discovery message of the terminal device is non-normally distributed. If so, update the penalty factor of the terminal device, that is, P=P+1; otherwise, keep the penalty factor of the terminal device unchanged, that is, P=P.

[0109] S67: Determine whether the transmission power of the proximity discovery message of the terminal device is greater than the first value. If so, update the penalty factor of the terminal device, that is, P=P+1; otherwise, keep the penalty factor of the terminal device unchanged, that is, P=P.

[0110] S68: Output the penalty factor P of the terminal device.

[0111] It should be noted that the embodiment of the present application does not limit the execution order of steps S63 to S67.

[0112] It should be noted that the penalty factors corresponding to the above parameters can be equal or different. For example, the parameter "RSSI of proximity discovery message" is more important, and the penalty factor corresponding to "RSSI of proximity discovery message" can be set larger (such as the penalty factor is 2).

[0113] It can be seen that in this embodiment, the first distance between the terminal device and the Bluetooth peripheral is not only related to the physical distance between the terminal device and the Bluetooth peripheral, but also to at least one parameter of the terminal device's screen state, running application, AR state, RSSI of the proximity discovery message, or the transmission power of the proximity discovery message. Since at least one parameter of the terminal device characterizes the scenario in which the user currently uses the terminal device, the penalty factor of the terminal device determined based on at least one parameter of the terminal device can characterize the user's current need to connect to the Bluetooth peripheral (such as when the penalty factor is large, the user's current need to connect to the Bluetooth peripheral is low; when the penalty factor is small, the user's current need to connect to the Bluetooth peripheral is high), then the first distance determined based on the penalty factor of the terminal device also characterizes the user's current need to connect to the Bluetooth peripheral. When the pairing notification is output on the terminal device with the shortest first distance, it is beneficial for the terminal device of the user who currently has a high need to connect to the Bluetooth peripheral to establish a connection with the Bluetooth peripheral.

[0114] S502: Each of the other terminal devices sends the first information of the terminal device to the first terminal device. Correspondingly, the first terminal device receives the first information of the terminal device from each of the other terminal devices.

[0115] Among them, the first information of each terminal device among the other terminal devices includes the physical distance between the terminal device and the Bluetooth peripheral device; or, the first information of each terminal device among the other terminal devices includes at least one parameter of the terminal device's screen status, running applications, AR status, RSSI of proximity discovery messages, and transmission power of proximity discovery messages, as well as the physical distance between the terminal device and the Bluetooth peripheral device.

[0116] Optionally, the first information of each terminal device may also include other data, such as an identifier of the terminal device, an identifier of a Bluetooth peripheral, etc., without limitation. Optionally, the identifier may be a Media Access Control (MAC) address or other identifiers.

[0117] In an optional implementation, the first information of each terminal device is sent in the form of a broadcast message. Optionally, the broadcast message can be sent using a corresponding broadcast starting point, broadcast interval, and broadcast duration. For example, the broadcast message of each terminal device is sent with a broadcast starting point when the physical distance between the terminal device and the Bluetooth peripheral is detected to be within the first range, a broadcast interval of 20 seconds, and a broadcast duration of 30 seconds.

[0118] In an optional implementation manner, the first terminal device may also use the corresponding receiving start point, receiving interval, and receiving duration to receive the broadcast message, which will not be described in detail.

[0119] An optional implementation manner, in which the first terminal device receives the first information of the terminal device from each of the other terminal devices, includes: the first terminal device needs to filter out useless information from all information to obtain the first information of each of the other terminal devices. For example, the broadcast message may also carry data transmission information. In this case, the first terminal device needs to filter out the data transmission information from the broadcast message to obtain the first information of each of the other terminal devices. For another example, the broadcast message may also carry the first information related to other Bluetooth peripherals (such as the first information including the physical distance between the terminal device and other Bluetooth peripherals in other terminal devices). In this case, the first terminal device needs to filter out the first information related to other Bluetooth peripherals from the broadcast message to obtain the first information of each of the other terminal devices.

[0120] S503: The first terminal device determines the first distance between the first terminal device and the Bluetooth peripheral device based on the first information of each terminal device in other terminal devices.

[0121] Based on implementation 1.1, step S503 specifically includes: based on the first information, taking the physical distance between each terminal device in other terminal devices and the Bluetooth peripheral device as the first distance between the terminal device and the Bluetooth peripheral device. The first information includes the physical distance between the terminal device in other terminal devices and other Bluetooth peripheral devices.

[0122] Based on implementation 1.2, step S501 specifically includes: the first terminal device determines the penalty factor of the terminal device based on at least one parameter of the screen state, running application, AR state, RSSI of the proximity discovery message, or the transmission power of the proximity discovery message of each terminal device in the other terminal devices in the first information; and multiplies the physical distance between the terminal device and the Bluetooth peripheral in the first information by the penalty factor of the terminal device to obtain the first distance between the terminal device and the Bluetooth peripheral. Among them, the first information includes the first information of each terminal device in the other terminal devices, including at least one parameter of the screen state, running application, AR state, RSSI of the proximity discovery message, and the transmission power of the proximity discovery message of the terminal device, and the physical distance between the terminal device and the Bluetooth peripheral.

[0123] It should be noted that for the specific related description, please refer to step S501 and will not be repeated here.

[0124] S504: The first terminal device determines whether the first distance between the first terminal device and the Bluetooth peripheral device is smaller than the first distance between the other terminal devices and the Bluetooth peripheral device based on the first distances between the first terminal device and the other terminal devices and the Bluetooth peripheral device respectively.

[0125] S505: If yes, the first terminal device outputs a pairing notification; the pairing notification is used to notify that the first terminal device is allowed to establish a Bluetooth pairing with the Bluetooth peripheral device.

[0126] In an optional implementation, if the first distance between the first terminal device and the Bluetooth peripheral is smaller than the first distance between other terminal devices and the Bluetooth peripheral, a pairing notification is output on the first terminal device; if there are other terminal devices whose first distance to the Bluetooth peripheral is smaller than the first distance between the first terminal device and the Bluetooth peripheral, the first terminal device discards the proximity discovery message. It should be noted that the proximity discovery message may be received by the first terminal device before determining the physical distance between itself and the Bluetooth peripheral. In other words, the Bluetooth peripheral sends a proximity discovery message, and accordingly, the first terminal device can receive the proximity discovery message, and execute steps S501 to S505 in response to the proximity discovery message. In addition, when there are other terminal devices whose first distance to the Bluetooth peripheral is smaller than the first distance between the first terminal device and the Bluetooth peripheral, the first terminal device discards the received proximity discovery message.

[0127] Optionally, the Bluetooth peripheral may send a proximity discovery message when the pairing mode is turned on. For example, when the Bluetooth peripheral is used for the first time and turned on, the Bluetooth peripheral enters the pairing mode and sends a proximity discovery message. Taking a Bluetooth headset as an example, when the Bluetooth headset is used for the first time and the headset box is opened, the Bluetooth headset is turned on for the first time, the Bluetooth headset enters the pairing mode and sends a proximity discovery message.

[0128] In an optional implementation, if the first distance between the first terminal device and the Bluetooth peripheral is smaller than the first distance between the other terminal devices and the Bluetooth peripheral, the method further includes: determining whether the first distance between the first terminal device and the Bluetooth peripheral is within the second range; if the first distance between the first terminal device and the Bluetooth peripheral is within the second range, outputting a pairing notification on the first terminal device; if the first distance between the first terminal device and the Bluetooth peripheral is outside the second range, the first terminal device discards the proximity discovery message. Wherein, the second range can also be any distance interval, for example, the second range is a distance interval of 20 cm to 50 cm, a distance interval of 1 m to 3 m, etc., without limitation. It can be seen that in this implementation, the first distance between the first terminal device and the Bluetooth peripheral can be further compared with the second range, and the pairing notification is output only when the first distance between the first terminal device and the Bluetooth peripheral is within the second range, and the pairing notification is not output when the first distance between the first terminal device and the Bluetooth peripheral is outside the second range, further reducing the probability of the terminal device and the Bluetooth peripheral establishing a Bluetooth connection, thereby further reducing the probability of data leakage via the Bluetooth connection, and further ensuring the security of the data.

[0129] It should be noted that the embodiment of the present application does not limit the execution order of step S501 and step S502 to step S503. For example, step S501 may be executed first, and then step S502 to step S503; for another example, step S502 to step S503 may be executed first, and then step S501; for another example, step S501 and step S502 to step S503 may be executed simultaneously.

[0130] It can be seen that in the embodiment of the present application, the first terminal device can receive the first information of its terminal device, and determine the first distance between other terminal devices and the Bluetooth peripheral device based on the first information of other terminal devices, so that the first terminal device can judge whether the first terminal device itself is the terminal device with the shortest first distance between the Bluetooth peripheral device and the first distance between other terminal devices and the Bluetooth peripheral device based on the first distance between itself and the Bluetooth peripheral device and the first distance between other terminal devices and the Bluetooth peripheral device. When the first terminal device determines that it is the terminal device with the shortest first distance between itself and the Bluetooth peripheral device, the first terminal device outputs a pairing notification; when the first terminal device determines that it is not the terminal device with the shortest first distance between itself and the Bluetooth peripheral device, the first terminal device does not output a pairing notification (i.e., discards the proximity discovery message). In addition, since the present application scheme is executed by the first terminal device, the first terminal device can directly determine the first distance between itself and the Bluetooth peripheral device, which is conducive to the first terminal device to more timely judge whether it is the terminal device with the shortest first distance between itself and the Bluetooth peripheral device, and the user experience is better.

[0131] Need to explain, Figure 5 The method described is described by taking the first terminal device executing the embodiment of the present application as an example. For the description of other terminal devices executing the embodiment of the present application, please refer to Figure 5 The related embodiments are not described in detail.

Figure 7 The method described Figure 4 Compared with the method described above, Figure 7 The method described is described by taking the example of a management device executing the solution of the embodiment of the present application. Figure 7 As shown, the method includes but is not limited to:

[0133] S701: The first terminal device sends first information of the first terminal device to the management device. Correspondingly, the management device receives the first information of the first terminal device from the first terminal device.

[0134] Among them, the first information of the first terminal device includes the physical distance between the first terminal device and the Bluetooth peripheral device; or, the first information of the first terminal device includes at least one parameter of the screen status, running applications, AR status, RSSI of the proximity discovery message, and transmission power of the proximity discovery message of the first terminal device, and the physical distance between the first terminal device and the Bluetooth peripheral device.

[0135] It should be noted that other descriptions about the first information of the first terminal device can be found in step S502 and will not be repeated here.

[0136] S702: The management device determines a first distance between the first terminal device and the Bluetooth peripheral device based on the first information of the first terminal device.

[0137] It should be noted that for the related description, please refer to step S501 and no further description will be given.

[0138] S703: Each of the other terminal devices sends the first information of the terminal device to the management device. Correspondingly, the management device receives the first information of the terminal device from each of the other terminal devices.

[0139] It should be noted that for the related description, please refer to step S502 and no further description will be given.

[0140] S704: The management device determines the first distance between each terminal device and the Bluetooth peripheral device based on the first information of each terminal device in other terminal devices.

[0141] It should be noted that for the related description, please refer to step S503 and no further description will be given.

[0142] S705: The management device determines whether the first distance between the first terminal device and the Bluetooth peripheral device is smaller than the first distance between the other terminal devices and the Bluetooth peripheral device based on the first distances between the first terminal device and the other terminal devices and the Bluetooth peripheral device respectively.

[0143] S706: If yes, a pairing notification is output on the first terminal device; the pairing notification is used to notify that the first terminal device is allowed to establish a Bluetooth pairing with the Bluetooth peripheral device.

[0144] In an optional implementation, outputting a pairing notification on the first terminal device includes: the management device sends a first instruction to the first terminal device, where the first instruction is used to instruct the first terminal device to output a pairing notification.

[0145] It should be noted that for other related descriptions of step S705 and step S706, please refer to Figure 4 The related embodiments are not described in detail.

[0146] In an optional implementation, step S705 and step S706 may be replaced as follows: the management device determines the terminal device with the shortest first distance between the first terminal device and the other terminal devices and the Bluetooth peripheral based on the first distances between the first terminal device and the other terminal devices and the Bluetooth peripheral respectively, and outputs a pairing notification on the terminal device with the shortest first distance between the first terminal device and the Bluetooth peripheral.

[0147] It should be noted that the embodiment of the present application does not limit the execution order of steps S701 to S702 and steps S703 to S704. For example, steps S701 to S702 may be executed first, and then steps S703 to S704; for another example, steps S703 to S704 may be executed first, and then steps S701 to S702; for another example, steps S701 to S702 and steps S703 to S704 may be executed simultaneously.

[0148] It can be seen that in the embodiment of the present application, the management device can receive the first information of the first terminal device, and determine the first distance between the first terminal device and the Bluetooth peripheral device based on the first information of the first terminal device, and receive the first information of other terminal devices, and determine the first distance between other terminal devices and the Bluetooth peripheral device based on the first information of other terminal devices, and determine the terminal device with the shortest first distance between the first terminal device and the other terminal devices and the Bluetooth peripheral device based on the first distance between the first terminal device and the other terminal devices, and output a pairing notification on the terminal device. For example, when it is determined that the first terminal device is the terminal device with the shortest first distance between the first terminal device and the Bluetooth peripheral device, a pairing notification is output on the first terminal device. In addition, since the scheme of the present application is executed by the management device, the management device can directly determine the terminal device with the shortest first distance between the first terminal device and the Bluetooth peripheral device from multiple terminal devices, without each terminal device having to determine whether it is the terminal device with the shortest first distance between the Bluetooth peripheral device, which can reduce the data processing steps, reduce the data processing flow, and save data processing resources.

[0149] See also Figure 8 , Figure 8 The structure diagram of the electronic device 100 provided in the embodiment of the present application is shown. The embodiment is specifically described below by taking the electronic device 100 as the first terminal device as an example. It should be understood that: Figure 8 The electronic device 100 shown is only an example, and the electronic device 100 may have more Figure 8 More or fewer components may be shown, two or more components may be combined, or there may be a different configuration of components.

[0153] In some embodiments, the processor 110 may be used to determine whether the first distances between the electronic device 100 and the Bluetooth peripheral device are smaller than the first distances between other terminal devices and the Bluetooth peripheral device.

[0154] The controller can generate operation control signals according to the instruction operation code and timing signal to complete the control of instruction fetching and execution.

[0155] The processor 110 may also be provided with a memory for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. 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.

[0156] In some embodiments, the processor 110 may include one or more interfaces. The interface may include an inter-integrated circuit (I2C) interface, an inter-integrated circuits sound (I2S) interface, a pulse code modulation (PCM) interface, a universal asynchronous receiver / transmitter (UART) interface, a mobile industry processor interface (MIPI), a general-purpose input / output (GPIO) interface, a subscriber identity module (SIM) interface, and / or a universal serial bus (USB) interface, etc.

[0157] The I2C interface is a bidirectional synchronous serial bus, including a serial data line (SDA) and a serial clock line (SCL). In some embodiments, the processor 110 may include multiple groups of I2C buses. The processor 110 may be coupled to the touch sensor 180K, the charger, the flash, the camera 193, etc. through different I2C bus interfaces. For example: the processor 110 may be coupled to the touch sensor 180K through the I2C interface, so that the processor 110 communicates with the touch sensor 180K through the I2C bus interface, thereby realizing the touch function of the electronic device 100.

[0158] The I2S interface can be used for audio communication. In some embodiments, the processor 110 can include multiple I2S buses. The processor 110 can be coupled to the audio module 170 via the I2S bus to achieve communication between the processor 110 and the audio module 170.

In some embodiments, the audio module 170 and the wireless communication module 160 can be coupled via a PCM bus interface. In some embodiments, the audio module 170 can also transmit audio signals to the wireless communication module 160 via the PCM interface to realize the function of answering calls via a Bluetooth headset. Both the I2S interface and the PCM interface can be used for audio communication.

[0160] The UART interface is a universal serial data bus for asynchronous communication. The bus can be a bidirectional communication bus. It converts the data to be transmitted between serial communication and parallel communication. In some embodiments, the UART interface is generally used to connect the processor 110 and the wireless communication module 160. For example, the processor 110 communicates with the Bluetooth module in the wireless communication module 160 through the UART interface to implement the Bluetooth function. In some embodiments, the audio module 170 can transmit an audio signal to the wireless communication module 160 through the UART interface to implement the function of playing music through a Bluetooth headset.

[0161] The MIPI interface can be used to connect the processor 110 with peripheral devices such as the display screen 194 and the camera 193. The MIPI interface includes a camera serial interface (CSI), a display serial interface (DSI), etc. In some embodiments, the processor 110 and the camera 193 communicate via the CSI interface to implement the shooting function of the electronic device 100. The processor 110 and the display screen 194 communicate via the DSI interface to implement the display function of the electronic device 100.

[0162] The GPIO interface can be configured by software. The GPIO interface can be configured as a control signal or as a data signal. In some embodiments, the GPIO interface can be used to connect the processor 110 with the camera 193, the display 194, the wireless communication module 160, the audio module 170, the sensor module 180, etc. The GPIO interface can also be configured as an I2C interface, an I2S interface, a UART interface, a MIPI interface, etc.

[0163] The USB interface 130 is an interface that complies with the USB standard specification, and specifically can be a Mini USB interface, a Micro USB interface, a USB Type C interface, etc. The USB interface 130 can be used to connect a charger to charge the electronic device 100, and can also be used to transfer data between the electronic device 100 and a peripheral device. It can also be used to connect headphones to play audio through the headphones. The interface can also be used to connect other electronic devices, such as AR devices, etc.

[0164] 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.

[0165] The charging management module 140 is used to receive charging input from a charger. The charger may be a wireless charger or a wired charger. In some wired charging embodiments, the charging management module 140 may receive charging input from a wired charger through the USB interface 130. In some wireless charging embodiments, the charging management module 140 may receive wireless charging input through a wireless charging coil of the electronic device 100.

The embodiment of the present application takes the Android system of the layered architecture as an example to exemplify the software structure of the electronic device 100.

[0210] Fig. 9 It is a software structure block diagram of the electronic device 100 according to an embodiment of the present application.

[0211] The layered architecture divides the software into several layers, each with clear roles and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, from top to bottom: the application layer, the application framework layer, the Android runtime and system library, and the kernel layer.

[0217] 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.

[0218] 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.

[0219] The phone manager is used to provide communication functions of the electronic device 100, such as management of call status (including connecting, hanging up, etc.).

[0220] The resource manager provides various resources for applications, such as localized strings, icons, images, layout files, video files, and so on.

[0221] The notification manager enables applications to display notification information in the status bar.

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 a notification of an application running in the background, or a notification that appears on the screen in the form of a dialog window (such as the pairing notification involved in the embodiment of the present application). For example, a text message is prompted in the status bar, a prompt sound is emitted, the electronic device vibrates, the indicator light flashes, etc.

[0222] Android Runtime includes core libraries and virtual machines. Android runtime is responsible for scheduling and management of the Android system.

[0223] 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.

[0224] 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.

[0228] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

[0229] A 2D graphics engine is a drawing engine for 2D drawings.

[0230] The kernel layer is the layer between hardware and software. The kernel layer contains at least display driver, camera driver, audio driver, and sensor driver.

[0231] The following is an illustrative description of the workflow of the software and hardware of the electronic device 100 in conjunction with a Bluetooth pairing scenario.

[0232] When the touch sensor 180K receives a touch operation, the corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the touch operation into raw input events (including touch coordinates, timestamp of the touch operation, and other information). The raw input events are stored in the kernel layer. The application framework layer obtains the raw input events from the kernel layer and identifies the control corresponding to the input event. For example, if the touch operation is a touch single-click operation and the control corresponding to the single-click operation is an allowed control for pairing notification, the Bluetooth application calls the interface of the application framework layer, and then starts iconnect by calling the kernel layer, and establishes a Bluetooth connection through iconnect.
