The present disclosure relates to the field of communication technologies, and more specifically, to a control method, a sharing method, a device, and a system in the field of communication technologies.
With rapid development of communication technologies and artificial intelligence, Bluetooth-based devices (which may be referred to as Bluetooth devices, including a classic Bluetooth (BT) device, a Bluetooth Low Energy (BLE) device, and the like) such as wearable devices (a watch, a headset, and the like) and smart speakers are widely used. When a Bluetooth device needs to be connected, a pairing mode needs to be entered first (which requires that the Bluetooth device is able to be discovered and connected), and then searching, pairing, and connecting are performed. An entire process is complex and may cause existing connections to be interrupted.
In addition, regardless of whether the Bluetooth device is the classic BT device or the BLE device, the Bluetooth device does not have a concept of use permission or management permission. In other words, any user who gets a Bluetooth device only needs to perform simple operations on the Bluetooth device (such as powering on or off, or pressing and holding a function button), to reset the Bluetooth device to enter a pairing mode, to obtain the use permission or management permission of the Bluetooth device. In a scenario in which a Bluetooth device is lost, security of the Bluetooth device is low.
Therefore, a technical solution that can improve security of a Bluetooth device is urgently needed.
Embodiments of the present disclosure provide a control method, a sharing method, a device, and a system, to improve security of a Bluetooth device and implement sharing of the Bluetooth device.
According to a first aspect, an embodiment of the present disclosure provides a control method, where the control method may include: A second device (for example, a smartphone A having a Bluetooth function) establishes a pairing connection to a first device (for example, a vehicle-mounted device B having the Bluetooth function). The second device sends a first message to the first device, and receives a second message sent by the first device based on the first message.
The first message may indicate that the second device is able to share a connection. Herein, it may be understood as that the first message indicates that the second device supports a secure sharing function. If the second device does not support the secure sharing function, the second device has only use permission but does not have management permission for the first device. The second message indicates that the first device is able to share a connection (which may be understood as that the first device supports the secure sharing function), and the first device sets the second device as a management device.
It may be understood that a process in which the second device sends the first message to the first device and the first device sends the second message to the second device may be considered as secure sharing function interaction between the second device and the first device. In addition, when the first device sets the second device as the management device, the second device becomes a manager of the first device. In other words, the second device has the use permission (which may be permanent use permission) and the management permission for the first device, and the first device may record the use permission and the management permission of the second device.
According to the control method provided in the first aspect of embodiments of the present disclosure, on a basis that the first device and the second device establish the pairing connection, the second device can control the first device, so that security of the first device is improved.
For example, the first device may be in a factory setting state, or may be in an unmanaged state. Therefore, when the first device is connected to another device such as the second device as an accessory device for the first time, the second device automatically becomes the management device of the first device.
In a possible implementation, the pairing connection may be established between the second device and the first device in the following two manners.
Manner 1: The first device enters a searching state, and the second device searches for the first device, and establishes the pairing connection to the first device.
Manner 2: The first device and the second device establish the pairing connection through proximity discovery (for example, a near-field communication (NFC) function of a smartphone or broadcast scanning performed by the second device).
It should be noted that the foregoing two manners may be used to implement the pairing connection between the second device and the first device, and another manner than the foregoing two manners may further be used to implement the pairing connection between the second device and the first device. This is not limited in this embodiment of the present disclosure.
In a possible implementation, after that the second device receives a second message sent by the first device based on the first message, the second device may further send a third message to the first device. The third message may indicate that the first device is prohibited from being scanned. In other words, a purpose of sending, by the second device, the third message to the first device is to enable the first device to disable a pairing connection function.
In another possible implementation, after that the second device receives a second message sent by the first device based on the first message, the second device may further send a fourth message to the first device. The fourth message indicates that the first device resumes being scanned. In other words, a purpose of sending, by the second device, the fourth message to the first device is to enable the first device to resume the pairing connection function.
In this embodiment of the present disclosure, the second device sends, to the first device, the third message that indicates that the first device is prohibited from being scanned or the fourth message that indicates that the first device resumes being scanned, so that the second device separately manages and controls the first device (that is, the second device exclusively controls the first device). The first device can be used only under control of the second device, and a control process is simple and easy to implement. In addition, the second device may manage all connected and paired devices of the first device.
According to a second aspect, an embodiment of the present disclosure provides a control method, where the control method may include: A first device establishes a pairing connection to a second device. The first device receives a first message from the second device. The first device sends a second message to the second device based on the first message.
For detailed descriptions of the first message and the second message, refer to the foregoing descriptions.
According to the control method provided in the second aspect of embodiments of the present disclosure, on a basis that the first device and the second device establish the pairing connection, the second device can control the first device, so that security of the first device is improved.
In a possible implementation, after that the first device sends a second message to the second device, the first device may further receive a third message from the second device. The third message may indicate that the first device is prohibited from being scanned. In other words, a purpose of sending, by the second device, the third message to the first device is to enable the first device to disable a pairing connection function.
Further, after the first device receives the third message, the first device may record the third message, and no longer respond to another device than the second device. It should be noted that, because the second device may further be connected to the first device, even if the first device enters a mode of being prohibited from being scanned, the first device may still be in a mode in which the first device can be connected.
In another possible implementation, after that the first device sends a second message to the second device, the first device may further receive a fourth message from the second device. The fourth message indicates that the first device resumes being scanned. In other words, a purpose of sending, by the second device, the fourth message to the first device is to enable the first device to resume the pairing connection function.
Further, after the first device receives the fourth message, the first device records the fourth message, and responds to another device than the second device again. The first device may enter a mode of resuming being scanned (or may be considered as a mode in which the first device resumes being paired and connected) by performing operations such as powering on or off, or pressing and holding a function button.
In this embodiment of the present disclosure, the second device sends, to the first device, the third message that indicates that the first device is prohibited from being scanned or the fourth message that indicates that the first device resumes being scanned, so that the second device manages and controls the first device, and a control process is simple and easy to implement.
Because the first device is an accessory device of the second device, even if the second device is a manager of the first device, information such as an address book needs to be synchronized each time the second device is disconnected and reconnected to the first device. When a large amount of information such as the address book needs to be synchronized, the synchronization takes long time. In addition, when a user lends the first device to a third device (for example, a smartphone C of a user C), the third device may use the first device. In this case, the first device is shared. When the first device (such as a vehicle-mounted device B) is shared, there is a risk of leakage of information such as a contact, a call record, or a text message that are of the second device and that are stored in the first device. Therefore, the first device needs to be shared with the third device through the second device, and permission (use permission and/or management permission) of the third device to use the first device needs to be set, to reduce a risk of information leakage of the second device.
Therefore, according to a third aspect, an embodiment of the present disclosure provides a sharing method, where the sharing method may include: A second device establishes a pairing connection to a first device. The second device sends a first message to the first device. The second device receives a second message sent by the first device based on the first message. The second device sends the first message to a third device (for example, a smartphone C having a Bluetooth function), sends information that is of the third device and that is fed back by the third device based on the first message to the first device, and sends information of the first device to the third device. The second device receives connection information fed back by the third device based on the information of the first device, and sends a management instruction to the first device based on the connection information.
For detailed descriptions of the first message and the second message, refer to the foregoing descriptions.
It should be noted that the information of the third device may include address information and/or name information of the third device.
It should be further noted that the information of the first device may include at least one of address information, name information, a device form (where for example, the first device is a vehicle-mounted device rather than a Bluetooth headset), a device type (for example, a classic BT and/or a BLE), and device information (for example, profile information and service information) of the first device.
In a possible implementation, in a process in which the second device sends the information that is of the third device and that is fed back by the third device to the first device, and sends the information of the first device to the third device, the second device may further send, to the first device and the third device, a verification code randomly generated by the second device, so that sharing security is improved, and speed of connection sharing is further accelerated.
According to the sharing method provided in this embodiment of the present disclosure, on a basis that the first device and the second device establish the pairing connection, the second device can control the first device. In addition, on a basis that the second device controls the first device, the second device can share the first device with the third device. The third device can establish a sharing connection to the first device only through sharing by the second device, so that security of the first device is improved, and leakage of information stored in the first device is also prevented.
In a possible implementation, after that the second device receives a second message sent by the first device based on the first message, the second device may further send a third message to the first device. The third message may indicate that the first device is prohibited from being scanned. In other words, a purpose of sending, by the second device, the third message to the first device is to enable the first device to disable a pairing connection function.
In another possible implementation, after that the second device receives a second message sent by the first device based on the first message, the second device may further send a fourth message to the first device. The fourth message indicates that the first device resumes being scanned. In other words, a purpose of sending, by the second device, the fourth message to the first device is to enable the first device to resume the pairing connection function.
In this embodiment of the present disclosure, the second device sends, to the first device, the third message that indicates that the first device is prohibited from being scanned or the fourth message that indicates that the first device resumes being scanned, so that the second device manages and controls the first device, and a control process is simple and easy to implement.
For example, the foregoing connection information may include first connection information and second connection information. The first connection information may indicate that the third device agrees to establish a sharing connection to the first device, and the second connection information indicates that the third device refuses to establish the sharing connection to the first device.
Optionally, the foregoing management instruction may include a sharing start instruction and a sharing termination instruction. The sharing start instruction indicates that the first device starts to establish the sharing connection to the third device, and the sharing termination instruction indicates that the first device terminates establishing the sharing connection to the third device.
Further, that the second device sends a management instruction to the first device based on the connection information may be classified into the following two cases.
Case 1: When the connection information is the first connection information, the second device may send the sharing start instruction to the first device.
Case 2: When the connection information is the second connection information, the second device may send the sharing termination instruction to the first device.
In this embodiment of the present disclosure, the second device sends the sharing start instruction/ sharing termination instruction to the first device based on the first connection information/ second connection information sent by the third device, so that the first device performs a corresponding operation based on the management instruction of the second device. Therefore, reliability of a control process is high, and security of the first device is also improved.
In a possible implementation, when the connection information is the first connection information, the second device receives device list information fed back by the first device based on the information of the third device, and changes permission information of the third device based on the device list information. The permission information includes management permission and/or use permission.
It should be noted that, because the second device is a management device of the first device, and the third device establishes a sharing connection to the first device through the second device, the third device usually has only one-time use permission (that is, the third device is a visitor of the first device).
In a possible implementation, the third device may determine the connection information based on the information of the first device. The connection information may include first connection information and second connection information. The first connection information may indicate that the third device agrees to establish a sharing connection to the first device, and the second connection information indicates that the third device refuses to establish the sharing connection to the first device.
Further, when the connection information is the first connection information, the third device may send the first connection information to the second device, and send a connection request to the first device. When the connection information is the second connection information, the third device sends the second connection information to the second device.
According to a fifth aspect, an embodiment of the present disclosure provides a sharing method, where the sharing method may include: A first device establishes a pairing connection to a second device. The first device receives a first message from the second device. The first device sends a second message to the second device based on the first message. The first device receives information of a third device from the second device, and enters a sharing mode. The first device receives a management instruction from the second device, and determines whether to establish a sharing connection to the third device based on the management instruction.
According to the sharing method provided in this embodiment of the present disclosure, on a basis that the first device and the second device establish a pairing connection, the first device is shared with the third device through the second device, so that security management and sharing of the first device are implemented, and security of the first device is improved. In addition, within a time range in which the first device enters the sharing mode, the first device may further receive a verification code randomly generated by the second device, to improve efficiency of pairing and connection between the third device and the first device. In addition, the first device may enter the sharing mode without disconnecting from the second device, which prevents a reconnection between the second device and the first device, and prevents repeated synchronization of information stored in the first device.
In a possible implementation, the third device may determine the connection information based on the information of the first device. The connection information may include first connection information and second connection information. The first connection information may indicate that the third device agrees to establish a sharing connection to the first device, and the second connection information indicates that the third device refuses to establish the sharing connection to the first device.
Further, when the connection information is the first connection information, the third device may send the first connection information to the second device, and send a connection request to the first device. When the connection information is the second connection information, the third device sends the second connection information to the second device.
According to a fifth aspect, an embodiment of the present disclosure provides a sharing method, where the sharing method may include: A first device establishes a pairing connection to a second device. The first device receives a first message from the second device. The first device sends a second message to the second device based on the first message. The first device receives information of a third device from the second device, and enters a sharing mode. The first device receives a management instruction from the second device, and determines whether to establish a sharing connection to the third device based on the management instruction.
According to the sharing method provided in this embodiment of the present disclosure, on a basis that the first device and the second device establish a pairing connection, the first device is shared with the third device through the second device, so that security management and sharing of the first device are implemented, and security of the first device is improved. In addition, within a time range in which the first device enters the sharing mode, the first device may further receive a verification code randomly generated by the second device, to improve efficiency of pairing and connection between the third device and the first device. In addition, the first device may enter the sharing mode without disconnecting from the second device, which prevents a reconnection between the second device and the first device, and prevents repeated synchronization of information stored in the first device.
In this embodiment of the present disclosure, the first device is not limited to the vehicle-mounted device B having the Bluetooth function described in the example in embodiments of the present disclosure. Provided that the first device has a wireless communication function, the third device can use (or manage) the first device through sharing by the second device.
In a possible implementation, that the first device receives a management instruction from the second device, and determines whether to establish a sharing connection to the third device based on the management instruction may be classified into the following two cases.
Case 1: When the management instruction is a sharing start instruction, the first device receives a connection request from the third device and the sharing start instruction from the second device, and establishes the sharing connection to the third device.
Case 2: When the management instruction is a sharing termination instruction, the first device exits the sharing mode. Herein, the following two aspects need to be described.
First, the third device unilaterally refuses to establish a sharing connection to the first device, and the third device may send second connection information to the second device. The second device may send the sharing termination instruction to the first device based on the second connection information, and then the first device exits the sharing mode.
Second, although the third device does not refuse to establish the sharing connection to the first device, that is, the third device agrees to establish the sharing connection to the first device, the first device does not receive the connection request from the third device within a time range in which the first device enters the sharing mode. In this case, the first device may actively exit the sharing mode.
Further, when the management instruction received by the first device from the second device is the sharing start instruction, the first device feeds back device list information to the second device based on the information of the third device.
According to the sharing method provided in this embodiment of the present disclosure, after the third device establishes the sharing connection to the first device, the first device feeds back the device list information to the second device based on the information of the third device, and permission information of the third device is changed through the second device, so that leakage of information stored in the first device is prevented, and sharing security is improved.
According to a sixth aspect, an embodiment of the present disclosure provides a second device (for example, a smartphone A), where the second device may include a connection module and a transceiver module. The connection module is configured to establish a pairing connection to a first device. The transceiver module is configured to: send a first message to the first device, and receive a second message sent by the first device based on the first message.
In this embodiment of the present disclosure, on a basis that the first device and the second device establish a pairing connection, through message exchange between the second device and the first device (where in other words, the second device sends the first message to the first device, and the second device may further receive the second message sent by the first device based on the first message), reliable control of the second device on the first device is implemented, and security of the first device is improved.
In a possible implementation, after the transceiver module of the second device receives the second message sent by the first device based on the first message, the transceiver module may further send a third message to the first device. The third message may indicate that the first device is prohibited from being scanned. In other words, a purpose of sending, by the second device, the third message to the first device is to enable the first device to disable a pairing connection function.
In another possible implementation, after the transceiver module of the second device receives the second message sent by the first device based on the first message, the transceiver module may further send a fourth message to the first device. The fourth message indicates that the first device resumes being scanned. In other words, a purpose of sending, by the second device, the fourth message to the first device is to enable the first device to resume the pairing connection function.
In this embodiment of the present disclosure, the second device sends, to the first device, the third message that indicates that the first device is prohibited from being scanned or the fourth message that indicates that the first device resumes being scanned, so that the second device manages and controls the first device, and a control process is simple and easy to implement.
Optionally, the transceiver module of the second device sends the first message to a third device, sends information that is of the third device and that is fed back by the third device based on the first message to the first device (which may be a transceiver module of the first device), and sends information of the first device to the third device. In addition, the transceiver module may further receive connection information fed back by the third device based on the information of the first device, and send a management instruction to the first device based on the connection information.
It should be noted that for detailed descriptions of the connection information and the management instruction, refer to the foregoing descriptions.
In a possible implementation, when the connection information is first connection information, the first connection information indicates that the third device agrees to establish a sharing connection to the first device, and the transceiver module of the second device may send a sharing start instruction to the first device. When the connection information is second connection information, the second connection information indicates that the third device refuses to establish the sharing connection to the first device, and the transceiver module of the second device may send a sharing termination instruction to the first device.
In this embodiment of the present disclosure, the second device sends the sharing start instruction/sharing termination instruction to the first device based on the first connection information/second connection information sent by the third device, so that the first device performs a corresponding operation based on the management instruction of the second device. Therefore, reliability of a control process is high, and security of the first device is also improved.
Optionally, when the connection information is the first connection information, the transceiver module of the second device may receive device list information fed back by the first device based on the information of the third device, and change permission information of the third device based on the device list information. The permission information may include management permission and/or use permission.
According to the sharing method provided in this embodiment of the present disclosure, when another device such as the third device uses the first device, the permission information of the third device may be changed (where for example, the third device may be changed from having only one-time use permission to having permanent use permission, or the third device may be changed from having only the one-time use permission to having permanent use permission and management permission (the third device also becomes a management device of the first device)), so that leakage of information stored in the first device is prevented, and sharing security is improved.
According to a seventh aspect, an embodiment of the present disclosure provides a first device (for example, a vehicle-mounted device B), where the first device may include a connection module and a transceiver module. The connection module may be configured to establish a pairing connection to a second device. The transceiver module may be configured to: receive a first message from the second device, and send a second message to the second device based on the first message.
In this embodiment of the present disclosure, on a basis that the first device and the second device establish a pairing connection, through message exchange between the second device and the first device (where in other words, the first device receives the first message sent by the second device, and the first device further sends the second message to the second device based on the first message), reliable control of the second device on the first device is implemented, and security of the first device is improved.
In a possible implementation, after the transceiver module of the first device sends the second message to the second device, the transceiver module may further receive a third message from the second device.
Further, after the transceiver module receives the third message, the transceiver module may record the third message, and no longer respond to another device than the second device. It should be noted that, because the second device may further be connected to the first device, even if the first device enters a mode of being prohibited from being scanned, the first device may still be in a mode in which the first device can be connected.
In another possible implementation, after the transceiver module of the first device sends the second message to the second device, the transceiver module may further receive a fourth message from the second device.
Further, after the transceiver module of the first device receives the fourth message, the transceiver module records the fourth message, and responds to another device than the second device again. The first device may enter a mode of resuming being scanned (or may be considered as a mode in which the first device resumes being paired and connected) by performing operations on the first device such as powering on or off, or pressing and holding a function button.
In this embodiment of the present disclosure, the second device sends, to the first device, the third message that indicates that the first device is prohibited from being scanned or the fourth message that indicates that the first device resumes being scanned, so that the second device manages and controls the first device, and a control process is simple and easy to implement.
In a possible implementation, the transceiver module of the first device may further receive information of a third device from the second device (which may be a transceiver module of the second device), and enter a sharing mode. In addition, the transceiver module of the first device may further receive a management instruction from the second device, and determine whether to establish a sharing connection to the third device based on the management instruction.
Further, when the management instruction is a sharing start instruction, the transceiver module of the first device may receive a connection request from the third device and the sharing start instruction from the second device, and establish the sharing connection to the third device. When the management instruction is a sharing termination instruction, the first device may exit the sharing mode. Herein, the following two aspects need to be described.
First, the third device unilaterally refuses to establish the sharing connection to the first device, and the third device may send second connection information to the second device. The second device may send the sharing termination instruction to the first device based on the second connection information, and then the first device eXits the sharing mode.
Second, although the third device does not refuse to establish the sharing connection to the first device, that is, the third device agrees to establish the sharing connection to the first device, the first device does not receive the connection request from the third device within a time range in which the first device enters the sharing mode. In this case, the first device may actively exit the sharing mode.
Optionally, the first device may further include a setting module. The setting module may set a time range for entering the sharing mode of the first device. If the connection request from the third device is not received within the time range, the first device eXits the sharing mode.
Further, when the management instruction received by the transceiver module of the first device from the second device is the sharing start instruction, the transceiver module feeds back device list information (refer to the foregoing descriptions, and details are not described herein again) to the second device based on the information of the third device.
According to a sharing method provided in this embodiment of the present disclosure, when another device such as the third device uses the first device, the second device may change the permission information of the third device (where for example, the third device may be changed from having only one-time use permission to having permanent use permission, or the third device may be changed from having only the one-time use permission to having permanent use permission and management permission (the third device also becomes a management device of the first device)), so that leakage of information stored in the first device is prevented, and sharing security is improved.
According to an eighth aspect, the present disclosure provides a third device (for example, a smartphone C), where the third device may include a receiving module and a sending module. The receiving module may be configured to: receive a first message from a second device (which may be a transceiver module of the second device), feed back information of the third device to the second device (which may be the transceiver module of the second device) based on the first message, and receive information of a first device sent by the second device (which may be the transceiver module of the second device). The sending module may be configured to feed back connection information determined based on the information of the first device to the second device (which may be the transceiver module of the second device).
In this embodiment of the present disclosure, on a basis that the second device and the first device establish a pairing connection, the first device is shared with the third device through the second device, so that the third device can use (or manage) the first device, and security of the first device is also improved.
In a possible implementation, the sending module may determine the connection information based on the information of the first device. In other words, the sending module may determine, based on the information of the first device, that the connection information is first connection information or second connection information. When the connection information is the first connection information, the sending module sends the first connection information to the second device (which may be the transceiver module of the second device), and sends a connection request to the first device (which may be a transceiver module of the first device). When the connection information is the second connection information, the sending module sends the second connection information to the second device (which may be the transceiver module of the second device).
In this embodiment of the present disclosure, the second device sends the sharing start instruction/ sharing termination instruction to the first device based on the first connection information/ second connection information sent by the third device, so that the first device performs a corresponding operation based on a management instruction of the second device. Therefore, reliability of a control process is high, and security of the first device is also improved.

The character“/” generally indicates that the associated objects are in an“or” relationship.“At least one of the following” or a similar expression thereof refers to any combination of these items, including any combination of singular items (pieces) or plural items (pieces). For example, at least one of a, b, or c may indicate a, b, c,“a and b”,“a and c”,“b and c”, or“a, b, and c”, where a, b, and c may be singular or plural.
With rapid development of communication technologies and artificial intelligence, Bluetooth devices (including a classic BT, a BLE, and the like) such as wearable devices (a watch having a Bluetooth function, a headset having the Bluetooth function, and the like) and audio devices (which may be a home smart speaker or a vehicle-mounted device, and the like) with the Bluetooth function are widely applied. When a Bluetooth device needs to be connected, the Bluetooth device needs to enter a pairing mode first (for example, the classic BT enters a pairing state, and the BLE enters a broadcast state), and then searching, pairing, and connecting are performed. The entire operation process is complex and may cause existing connections to be interrupted.
In addition, regardless of whether the Bluetooth device is the classic BT or the BLE, the Bluetooth device does not have a concept of use permission or management permission. In other words, any user only needs to perform simple operations on the Bluetooth device (such as powering on or off, or pressing and holding a function button (where some Bluetooth devices display a blue indicator or a red indicator and a blue indicator blink alternately when the user presses and holds a function button)), to reset the Bluetooth device to enter the pairing mode, so as to obtain use permission or management permission of the Bluetooth device. In a scenario such as loss of a Bluetooth device, security of the Bluetooth device is low.
For example, a user A is an owner of a Bluetooth device B (for example, a headset having the Bluetooth function or a watch having the Bluetooth function). Therefore, a smartphone A (having the Bluetooth function, and may be connected to the Bluetooth device B through the Bluetooth function) of the user A is a manager of the Bluetooth device B. It may be understood that the smartphone A has not only management permission for the Bluetooth device, but also use permission (which may be permanent use permission) for the Bluetooth device B. When a user C performs the foregoing simple operations on the Bluetooth device B, the Bluetooth device B can be reset to enter the pairing mode, so that the smartphone C of the user C (having the Bluetooth function, which can be used to connect the smartphone C to the Bluetooth device B) obtains not only the use permission of the Bluetooth device B, but also the management permission of the Bluetooth device B. It can be found that the smartphone C also becomes a manager of the Bluetooth device B. In other words, the smartphone A serving as a host and the smartphone C serving as a visitor have no difference in permission for the Bluetooth device B, that is, both have the use permission and the management permission for the Bluetooth device B.
To overcome the foregoing security problem of the Bluetooth device, an embodiment of the present disclosure provides a device information synchronization method based on a network cloud service. When the Bluetooth device is connected to the Internet, an account of an individual user may be logged in, to enable the Bluetooth device to automatically synchronize pairing information. In this method, the account of the individual user needs to be logged in, and the Bluetooth device further needs to be connected to the Internet. In a scenario without the Internet, the Bluetooth device cannot be used. In addition, this method is used to implement pairing information synchronization between a plurality of Bluetooth devices of an individual user, and cannot solve a problem that a Bluetooth device of a plurality of individual users is shared or temporarily borrowed.
To overcome the foregoing security problem of the Bluetooth device, a problem that the Bluetooth device cannot be used (including a problem that the Bluetooth device cannot be used due to no Internet, or a Bluetooth device of a plurality of individual users is shared or temporarily borrowed), and the like, an embodiment of the present disclosure provides a control method of a Bluetooth device by using a smartphone A (namely, a second device, or may be another device having a user interface (UI)) and a vehicle-mounted device B (namely, a first device, or may be an in-vehicle sound box that has a Bluetooth function, and is used as an accessory device of the second device). As shown in
Step S101: The smartphone A establishes a pairing connection to the vehicle-mounted device B.
Step S102: The smartphone A sends a first message M1 to the vehicle-mounted device B.
Step S103: The vehicle-mounted device B sends a second message M2 to the smartphone Abased on the first message M1.
Further, the first message M1 may indicate that the smartphone A is able to share a connection. Herein, it may be understood as that the first message M1 indicates that the smartphone A supports a secure sharing function. If the smartphone A does not support the secure sharing function, the smartphone A has only use permission for the vehicle-mounted device B, but does not have management permission. The second message M2 indicates that the vehicle-mounted device B is able to share a connection (which may be understood as that the vehicle-mounted device B supports the secure sharing function), and the vehicle-mounted device B sets the smartphone A as a management device.
It may be understood that a process in which the smartphone A sends the first message M1 to the vehicle-mounted device B and the vehicle-mounted device B sends the second message M2 to the smartphone A may be considered as secure sharing function interaction between the smartphone A and the vehicle-mounted device B. In addition, when the vehicle-mounted device B sets the smartphone A as the management device, the smartphone A becomes a manager of the vehicle-mounted device B. In other words, the smartphone A has the use permission (which may be permanent use permission) and the management permission for the vehicle-mounted device B, and the vehicle-mounted device B may record the use permission and the management permission of the smartphone A.
According to the control method provided in this embodiment of the present disclosure, on a basis that the vehicle-mounted device B and the smartphone A establish the pairing connection, the smartphone A can control the vehicle-mounted device B, so that security of the vehicle-mounted device B is improved.
For example, the vehicle-mounted device B may be in a factory setting state, or may be in an unmanaged state. Therefore, when the vehicle-mounted device B is connected to another device such as the smartphone A as an accessory device for the first time, the smartphone A automatically becomes the management device of the vehicle-mounted device B.
In a possible implementation, the pairing connection may be established between the smartphone A and the vehicle-mounted device B in the following two manners.
Manner 1: The vehicle-mounted device B enters a searching state, and the smartphone A searches for the smart device B, and establishes the pairing connection to the vehicle-mounted device B.
Manner 2: The vehicle-mounted device B and the smartphone A establish the pairing connection through proximity discovery (for example, an NFC function of a smartphone or broadcast scanning performed by the smartphone A).
It should be noted that the foregoing two manners may be used to implement the pairing connection between the smartphone A and the vehicle-mounted device B, and another manner than the foregoing two manners may further be used to implement the pairing connection between the smartphone A and the vehicle-mounted device B. This is not limited in this embodiment of the present disclosure.
In an example, after the vehicle-mounted device B sends the second message M2 to the smartphone A, as shown in
Further, after the vehicle-mounted device B receives the third message M3, the vehicle-mounted device B records the third message M3, and no longer responds to another device than the smartphone A. The vehicle-mounted device B may enter a mode of being prohibited from being scanned by performing operations on the vehicle-mounted device B such as powering on or off, or pressing and holding a function button. It should be noted that, because the smart device A may further be connected to the vehicle-mounted device B, even if the vehicle-mounted device B enters the mode of being prohibited from being scanned, the vehicle-mounted device B may still be in a mode in which the vehicle-mounted device B can be connected.
In another example, after the vehicle-mounted device B sends the second message M2 to the smartphone A, as shown in
Further, after the vehicle-mounted device B receives the fourth message M4, the vehicle-mounted device B records the fourth message M4, and responds to another device than the smartphone A again. The vehicle-mounted device B may enter a mode of resuming being scanned (or may be considered as a mode in which the vehicle-mounted device B resumes being paired and connected) by performing operations on the vehicle-mounted device B such as powering on or off, or pressing and holding a function button.
In this embodiment of the present disclosure, the smartphone A sends, to the vehicle-mounted device B, the third message that indicates that the vehicle-mounted device B is prohibited from being scanned or the fourth message that indicates that the vehicle-mounted device B resumes being scanned, so that the smartphone A separately manages and controls the vehicle-mounted device B (that is, the smartphone A exclusively controls the vehicle-mounted device B). The vehicle-mounted device B can be used only under control of the smartphone A, and a control process is simple and easy to implement. In addition, the smartphone Amay manage all connected and paired devices of the vehicle-mounted device B.
Because the vehicle-mounted device B is an accessory device of the smartphone A, even if the smartphone A is a manager of the vehicle-mounted device B, information such as an address book needs to be synchronized each time the smartphone A is disconnected and reconnected to the vehicle-mounted device B. When a large amount of information such as the address book needs to be synchronized, the synchronization takes long time. In addition, when the user A lends a vehicle to another user, the other user may use the vehicle-mounted device B. In this case, the vehicle-mounted device B is shared. When the vehicle-mounted device is shared, there is a risk of leakage of private information such as a contact, a call record, and a text message that are of the smartphone A and that are stored in the vehicle-mounted device B.
To prevent leakage of information stored in a vehicle-mounted device B and transmission of a large amount of duplicate data (for example, an address book of a smartphone A), an embodiment of the present disclosure provides a sharing method by using the smartphone A (namely, a second device), the vehicle-mounted device B (namely, a first device), and a smartphone C (namely, a third device) as an example, as shown in
Step S201: The smartphone A establishes a pairing connection to the vehicle-mounted device B.
Step S202: The smartphone A sends a first message M1 to the vehicle-mounted device B.
Step S203: The vehicle-mounted device B sends a second message M2 to the smartphone Abased on the first message M1.
Step S204: The smartphone A sends the first message M1 to the smartphone C.
Step S205: The smartphone C feeds back information of the smartphone C to the smartphone Abased on the first message M1.
Step S206: The smartphone A sends the information of the smartphone C to the vehicle-mounted device B.
Step S207: The vehicle-mounted device B receives the information of the smartphone C, and enters a sharing mode.
Step S208: The smartphone A sends information of the vehicle-mounted device B to the smartphone C.
Step S209: The smartphone C determines connection information based on the information of the vehicle-mounted device B, and sends the connection information to the smartphone A.
Step S210: The smartphone A sends a management instruction to the vehicle-mounted device B based on the connection information.
Step S211: The vehicle-mounted device B determines whether to establish a sharing connection to the smartphone C based on the management instruction.
Further, the first message M1 may indicate that the smartphone A is able to share a connection. Herein, it may be understood as that the first message M1 indicates that the smartphone A supports a secure sharing function. If the smartphone A does not support the secure sharing function, the smartphone A has only use permission for the vehicle-mounted device B, but does not have management permission. The second message M2 indicates that the vehicle-mounted device B is able to share a connection (which may be understood as that the vehicle-mounted device B supports the secure sharing function), and the vehicle-mounted device B sets the smartphone A as a management device.
It may be understood that a process in which the smartphone A sends the first message M1 to the vehicle-mounted device B and the vehicle-mounted device B sends the second message M2 to the smartphone A may be considered as secure sharing function interaction between the smartphone A and the vehicle-mounted device B. In addition, when the vehicle-mounted device B sets the smartphone A as the management device, the smartphone A becomes a manager of the vehicle-mounted device B. In other words, the smartphone A has the use permission (which may be permanent use permission) and the management permission for the vehicle-mounted device B, and the vehicle-mounted device may record the use permission and the management permission of the smartphone A.
In a possible implementation, the information of the vehicle-mounted device B may include at least one of address information, name information, a device form (where for example, the device is the vehicle-mounted device B rather than a Bluetooth headset), a device type (for example, a classic BT and/or a BLE), and device information (for example, profile information and service information) of the vehicle-mounted device B.
In another possible implementation, in a process in which the smartphone A sends the information of the smartphone C to the vehicle-mounted device B and the smartphone A sends the information of the vehicle-mounted device B to the smartphone C, the smartphone A may further send a verification code randomly generated by the smartphone A to the vehicle-mounted device B and the smartphone C, so that sharing security is improved, and speed of connection sharing is further accelerated.
According to the foregoing sharing method in this embodiment of the present disclosure, on a basis that the vehicle-mounted device B and the smartphone A establish the pairing connection, the smartphone A can control the vehicle-mounted device B. In addition, on a basis that the smartphone A controls the vehicle-mounted device B, the smartphone A can share the vehicle-mounted device B with the smartphone C. The smartphone C can establish a sharing connection to the vehicle-mounted device B only through sharing by the smartphone A, so that security of the vehicle-mounted device B is improved, and leakage of information stored in the vehicle-mounted device B is also prevented.
In addition, within a time range in which the vehicle-mounted device B enters the sharing mode, the vehicle-mounted device B may receive the verification code randomly generated by the smartphone A, to improve connection efficiency between the smartphone C and the vehicle-mounted device B. In addition, the vehicle-mounted device B can enter the sharing mode without disconnecting from the smartphone A, which prevents a reconnection between the smartphone A and the vehicle-mounted device B, and prevents repeated synchronization of information stored in the vehicle-mounted device B.
In a possible implementation, the pairing connection may be established between the smartphone A and the vehicle-mounted device B in the following two manners.
Manner 1: The vehicle-mounted device B enters a searching state, and the smartphone A searches for the smart device B, and establishes the pairing connection to the vehicle-mounted device B.
Manner 2: The vehicle-mounted device B and the smartphone A establish the pairing connection through proximity discovery (for example, an NFC function of a smartphone or broadcast scanning performed by the smartphone A).
It should be noted that the foregoing two manners may be used to implement the pairing connection between the smartphone A and the vehicle-mounted device B, and another manner than the foregoing two manners may further be used to implement the pairing connection between the smartphone A and the vehicle-mounted device B. This is not limited in this embodiment of the present disclosure.
For example, the foregoing connection information LM may include first connection information LM1 and second connection information LM2. The first connection information LM1 may indicate that the smartphone C agrees to establish the sharing connection to the vehicle- mounted device B, and the second connection information LM2 indicates that the smartphone C refuses to establish the sharing connection to the vehicle-mounted device B.
Optionally, the management instruction M1 may include a sharing start instruction M11 and a sharing termination instruction M12. The sharing start instruction M11 indicates that the vehicle-mounted device B starts to establish the sharing connection to the smartphone C, and the sharing termination instruction M12 indicates that the vehicle-mounted device B terminates establishing the sharing connection to the smartphone C.
Further, that the smartphone A sends the management instruction M1 to the vehicle-mounted device B based on the connection information LM may be classified into the following two cases.
Case 1: When the connection information LM is the first connection information LM1, the smartphone A sends the sharing start instruction M11 to the vehicle-mounted device B.
Case 2: When the connection information LM is the second connection information LM2, the smartphone A sends the sharing termination instruction M12 to the vehicle-mounted device B.
In this embodiment of the present disclosure, the smartphone A sends the sharing start instruction/sharing termination instruction to the vehicle-mounted device B based on the first connection information/second connection information sent by the smartphone C, so that the smartphone B performs a corresponding operation based on the management instruction of the smartphone A. Therefore, reliability of a control process is high, and security of the vehicle-mounted device B is also improved.
In a possible implementation, when the management instruction M1 is the sharing start instruction M11, or in other words, the vehicle-mounted device B is about to start establishing the sharing connection to the smartphone C, the smartphone C sends a connection request to the vehicle-mounted device B. The vehicle-mounted device B receives the connection request and the sharing start instruction from the smartphone A, and establishes the sharing connection to the smartphone C.
In another possible implementation, when the management instruction MI is the sharing termination instruction MI2, the vehicle-mounted device B exits the sharing mode. Herein, the following two aspects need to be described.
First, the smartphone C unilaterally refuses to establish the sharing connection to the vehicle-mounted device B, and the smartphone C may send the second connection information LM2 to the smartphone A. The smartphone A may send the sharing termination instruction M12 to the vehicle-mounted device B based on the second connection information LM2, and then the vehicle-mounted device B exits the sharing mode.
Second, although the smartphone C does not refuse to establish the sharing connection to the vehicle-mounted device B, that is, the smartphone C agrees to establish the sharing connection to the vehicle-mounted device B, the vehicle-mounted device B does not receive the connection request from the smartphone C within a time range that is set by the vehicle-mounted device B to enter the sharing mode. In this case, the vehicle-mounted device B may actively exit the sharing mode.
In an example, the management instruction MI is the sharing start instruction M11, and the vehicle-mounted device B feeds back device list information to the smartphone A based on the information of the smartphone C. The smartphone A may change permission information of the smart device C based on the device list information. The permission information includes management permission and/or use permission.
According to the sharing method provided in this embodiment of the present disclosure, when another device such as the smartphone C uses the vehicle-mounted device B, the permission information of the smartphone C (in other words, a device associated with the vehicle-mounted device B) may be changed (where for example, the smartphone C may be changed from having only one-time use permission to having permanent use permission, or the smartphone C may be changed from having only the one-time use permission to having permanent use permission and management permission (the smartphone C also becomes a management device of the vehicle- mounted device B)), so that leakage of information stored in the vehicle-mounted device is prevented, and sharing security is improved.
It should be noted that, because the smartphone A is the management device of the vehicle-mounted device B, and the smartphone C establishes the sharing connection to the vehicle-mounted device B through the smartphone A, the smartphone C usually has only the one-time use permission (that is, the smartphone C is a visitor of the vehicle-mounted device B).
Optionally, the foregoing device list information may include at least one of address information, name information, permission information (such as management permission and/or use permission), and a connection status (such as connected and disconnected) of a device paired with the vehicle-mounted device B.
Further, the smartphone A changes the permission information of the smartphone C based on the address information, the name information, the permission information, the connection status, and the like that are fed back by the vehicle-mounted device B and that are of the device paired with the vehicle-mounted device B. That is, the smartphone A may perform privilege escalation or privilege degradation on the smartphone C.
In an example, the smartphone A may perform privilege escalation on the smartphone C. For example, the smartphone A changes the one-time use permission of the smartphone C to the permanent use permission, so that the smartphone C changes from the visitor of the vehicle-mounted device B to a common user. For another example, the smartphone A changes the permanent use permission of the smartphone C to the permanent use permission and management permission, so that the smartphone C changes from the common user of the vehicle-mounted device B to a manager.
In another example, the smartphone A may perform privilege degradation on the smartphone C. For example, the smartphone A changes the permanent use permission of the smartphone C to the one-time use permission, so that the smartphone C changes from the common user of the vehicle-mounted device to the visitor. For another example, the smartphone A changes the permanent use permission and management permission of the smartphone C to the permanent use permission, so that the smartphone C changes from the manager of the vehicle-mounted device B to the common user.
According to the sharing method provided in this embodiment of the present disclosure, when another device such as the smartphone C uses the vehicle-mounted device B, a quantity of connections between the smartphone C and the vehicle-mounted device can be limited through the management instruction sent by the smartphone A, and the permission information of the smartphone C may be further set (for example, the smartphone C may be set to have the one-time use permission or the permanent use permission of the vehicle-mounted device B), so that leakage of information stored in the vehicle-mounted device B is prevented, and sharing security is improved.
An embodiment of the present disclosure provides a smartphone A (namely, a second device), as shown in
Further, the first message M1 may indicate that the smartphone A is able to share a connection. Herein, it may be understood as that the first message M1 indicates that the smartphone A supports a secure sharing function. If the smartphone A does not support the secure sharing function, the smartphone A has only use permission for the vehicle-mounted device B, but does not have management permission. The second message M2 indicates that the vehicle-mounted device B is able to share a connection (which may be understood as that the vehicle-mounted device B supports the secure sharing function), and the vehicle-mounted device B sets the smartphone A as a management device.
It may be understood that a process in which the transceiver module A2 of the smartphone A sends the first message M1 to the vehicle-mounted device B and the vehicle- mounted device B sends the second message M2 to the transceiver module A2 of the smartphone A may be considered as secure sharing function interaction between the smartphone A and the vehicle-mounted device B. In addition, when the vehicle-mounted device B sets the smartphone A as the management device, the smartphone A becomes a manager of the vehicle-mounted device B. In other words, the smartphone A has the use permission (which may be permanent use permission) and the management permission for the vehicle-mounted device B, and the vehicle-mounted device B may record the use permission and the management permission of the smartphone A.
According to the technical solution provided in this embodiment of the present disclosure, on a basis that the smartphone A and the vehicle-mounted device B establish a pairing connection, the smartphone A can control the vehicle-mounted device B, so that security of the vehicle-mounted device B is improved.
For example, the vehicle-mounted device B may be in a factory setting state, or may be in an unmanaged state. Therefore, when the vehicle-mounted device B is connected to another device such as the smartphone A as an accessory device for the first time, the smartphone A automatically becomes the management device of the vehicle-mounted device B.
In a possible implementation, the transceiver module A2 may send a third message M3 to the vehicle-mounted device B. The third message M3 may indicate that the vehicle-mounted device B is prohibited from being scanned. In other words, a purpose of sending, by the transceiver module A2, the third message M3 to the vehicle-mounted device B is to enable the vehicle-mounted device B to disable a pairing connection function.
In another possible implementation, the transceiver module A2 may send a fourth message M4 to the vehicle-mounted device B. The fourth message M4 indicates that the vehicle-mounted device B resumes being scanned. In other words, a purpose of sending, by the transceiver module A2, the fourth message M4 to the vehicle-mounted device B is to enable the vehicle-mounted device B to resume the pairing connection function.
Further, the transceiver module A2 may send the first message M1 to the smartphone C (refer to the following descriptions), send information that is of the smartphone C and that is fed back by the smartphone C based on the first message M1 to the vehicle-mounted device B, and send information of the vehicle-mounted device B to the smartphone C. In addition, the transceiver module A2 may further receive connection information LM fed back by the smartphone C based on the information of the vehicle-mounted device B, and send a management instruction M1 to the vehicle-mounted device B based on the connection information LM.
It should be noted that the information of the smartphone C may include address information and/or name information of the smartphone C.
It should be further noted that the information of the vehicle-mounted device B may include at least one of address information, name information, a device form (where for example, the device is the vehicle-mounted device B rather than a Bluetooth headset), a device type (for example, a classic Bluetooth BT and/or a Bluetooth low energy BLE), and device information (for example, profile (profile) information and service (service) information) of the vehicle-mounted device B.
For example, the foregoing connection information LM may include first connection information LM1 and second connection information LM2. The first connection information LM1 may indicate that the smartphone C agrees to establish a sharing connection to the vehicle-mounted device B, and the second connection information LM2 indicates that the smartphone C refuses to establish the sharing connection to the vehicle-mounted device B.
Optionally, the management instruction MI may include a sharing start instruction M11 and a sharing termination instruction M12. The sharing start instruction MIl indicates that the vehicle-mounted device B starts to establish the sharing connection to the smartphone C, and the sharing termination instruction M12 indicates that the vehicle-mounted device B terminates establishing the sharing connection to the smartphone C.
Further, that the transceiver module A2 sends the management instruction M1 to the vehicle-mounted device B based on the connection information LM may be classified into the following two cases.
Case 1: When the connection information LM is the first connection information LM1, the transceiver module A2 sends the sharing start instruction M11 to the vehicle-mounted device B.
Case 2: When the connection information LM is the second connection information LM2, the transceiver module A2 sends the sharing termination instruction M12 to the vehicle-mounted device B.
In a possible implementation, when the connection information LM is the first connection information LM1, the transceiver module A2 receives device list information fed back by the vehicle-mounted device B based on the information of the smartphone C, and changes permission information of the smartphone C based on the device list information. The permission information includes management permission and/or use permission.
It should be noted that, because the smartphone A is the management device of the vehicle-mounted device B, and the smartphone C establishes the sharing connection to the vehicle-mounted device B through the smartphone A, the smartphone C usually has only the one-time use permission (that is, the smartphone C is a visitor of the vehicle-mounted device B).
Optionally, the foregoing device list information may include at least one of address information, name information, permission information (such as management permission and/or use permission), and a connection status (such as connected and disconnected) of a device paired with the vehicle-mounted device B.
Further, the smartphone A changes the permission information of the smartphone C based on the address information, the name information, the permission information, the connection status, and the like that are fed back by the vehicle-mounted device B and that are of the device paired with the vehicle-mounted device B. That is, the smartphone A may perform privilege escalation or privilege degradation on the smartphone C.
In an example, the smartphone A may perform privilege escalation on the smartphone C. For example, the smartphone A changes the one-time use permission of the smartphone C to permanent use permission, so that the smartphone C changes from the visitor of the vehicle-mounted device B to a common user. For another example, the smartphone A changes the permanent use permission of the smartphone C to permanent use permission and management permission, so that the smartphone C changes from the common user of the vehicle-mounted device B to a manager.
In another example, the smartphone A may perform privilege degradation on the smartphone C. For example, the smartphone A changes the permanent use permission of the smartphone C to the one-time use permission, so that the smartphone C changes from the common user of the vehicle-mounted device to the visitor. For another example, the smartphone A changes the permanent use permission and management permission of the smartphone C to the permanent use permission, so that the smartphone C changes from the manager of the vehicle-mounted device B to the common user.
When the smartphone C uses the vehicle-mounted device B, the smartphone A may change the permission information of the smartphone C (where for example, the smartphone C may be changed from having only the one-time use permission to having the permanent use permission, or the smartphone C may be changed from having only the one-time use permission to having permanent use permission and management permission (the smartphone C also becomes a management device of the vehicle-mounted device B)), so that leakage of information stored in the vehicle-mounted device B is prevented, and sharing security is improved.
As shown in
Further, the first message M1 may indicate that the smartphone A is able to share a connection. Herein, it may be understood as that the first message M1 indicates that the smartphone A supports a secure sharing function. If the smartphone A does not support the secure sharing function, the smartphone A has only use permission for the vehicle-mounted device B, but does not have management permission. The second message M2 indicates that the vehicle-mounted device B is able to share a connection (which may be understood as that the vehicle-mounted device B supports the secure sharing function), and the vehicle-mounted device B sets the smartphone A as a management device.
It may be understood that a process in which the smartphone A sends the first message M1 to the vehicle-mounted device B and the vehicle-mounted device B sends the second message M2 to the smartphone A may be considered as secure sharing function interaction between the smartphone A and the vehicle-mounted device B. In addition, when the vehicle-mounted device B sets the smartphone A as the management device, the smartphone A becomes a manager of the vehicle-mounted device B. In other words, the smartphone A has the use permission (which may be permanent use permission) and the management permission for the vehicle-mounted device B, and the vehicle-mounted device B may record the use permission and the management permission of the smartphone A.
According to the technical solution provided in this embodiment of the present disclosure, on a basis that the smartphone A and the vehicle-mounted device B establish a pairing connection, the smartphone A can control the vehicle-mounted device B, so that security of the vehicle-mounted device B is improved.
For example, the vehicle-mounted device B may be in a factory setting state, or may be in an unmanaged state. Therefore, when the vehicle-mounted device B is connected to another device such as the smartphone A as an accessory device for the first time, the smartphone A automatically becomes the management device of the vehicle-mounted device B.
In a possible implementation, the transceiver module B2 may receive a third message M3 from the smartphone A (which may be the transceiver module A2 of the smartphone A). The third message M3 may indicate that the vehicle-mounted device B is prohibited from being scanned. In other words, a purpose of sending, by the transceiver module A2 of the smartphone A, the third message M3 to the vehicle-mounted device B is to enable the vehicle-mounted device B to disable a pairing connection function.
Further, the transceiver module B2 records the third message M3, and no longer responds to another device than the smartphone A. The vehicle-mounted device B may enter a mode of being prohibited from being scanned by performing operations on the vehicle-mounted device B such as powering on or off, or pressing and holding a function button. It should be noted that, because the smart device A may further be connected to the vehicle-mounted device B, even if the vehicle-mounted device B enters the mode of being prohibited from being scanned, the vehicle-mounted device B may still be in a mode in which the vehicle-mounted device B can be connected.
In another possible implementation, the transceiver module B2 may receive a fourth message M4 from the smartphone A (which may be the transceiver module A2 of the sm artphone A). The fourth message M4 indicates that the vehicle-mounted device B resumes being scanned. In other words, a purpose of sending, by the smartphone A, the fourth message M4 to the vehicle-mounted device B is to enable the vehicle-mounted device B to resume the pairing connection function.
Further, after the transceiver module B2 of the vehicle-mounted device B receives the fourth message M4, the transceiver module B2 records the fourth message M4, and responds to another device than the smartphone A again. The vehicle-mounted device B may enter a mode of resuming being scanned (or may be considered as a mode in which the vehicle-mounted device B resumes being paired and connected) by performing operations on the vehicle-mounted device B such as powering on or off, or pressing and holding a function button.
Optionally, the transceiver module A2 may receive information of the smartphone C from the smartphone A (which may be the transceiver module A2 of the smartphone A), and enter a sharing mode. The transceiver module A2 may further receive a management instruction from the transceiver module A2 of the smartphone A, and determine whether to establish a sharing connection to the smartphone C based on the management instruction.
It should be noted that the information of the smartphone C may include address information and/or name information of the smartphone C.
In a possible implementation, when the management instruction M1 is a sharing start instruction M11, or in other words, the vehicle-mounted device B is about to start establishing a sharing connection to the smartphone C, the transceiver module B2 receives a connection request sent by the smartphone C and the sharing start instruction M11 from the smartphone A, and establishes a sharing connection to the smartphone C.
In another possible implementation, when the management instruction M1 is the sharing termination instruction M12, the vehicle-mounted device B may exit the sharing mode. Herein, the following two aspects need to be described.
First, the smartphone C unilaterally refuses to establish the sharing connection to the vehicle-mounted device B, and the smartphone C may send second connection information LM2 to the smartphone A. The smartphone A may send the sharing termination instruction M12 to the transceiver module B2 of the vehicle-mounted device B based on the second connection information LM2, and then the vehicle-mounted device B eXits the sharing mode.
Second, although the smartphone C does not refuse to establish the sharing connection to the vehicle-mounted device B, that is, the smartphone C agrees to establish the sharing connection to the connection module B2 of the vehicle-mounted device B, the transceiver module B2 of the vehicle-mounted device B does not receive the connection request from the smartphone C within a time range that is set by the vehicle-mounted device B to enter the sharing mode. In this case, the vehicle-mounted device B may actively exit the sharing mode.
In still another possible implementation, the vehicle-mounted device B may further include a setting module B3. The setting module B3 may set a time range (for example, 3 minutes) in which the vehicle-mounted device B enters the sharing mode. If the vehicle-mounted device B does not receive the connection request sent by the smart device C within the time range, the vehicle-mounted device B may exit the sharing mode.
Within the time range in which the vehicle-mounted device B enters the sharing mode, the vehicle-mounted device B may receive a verification code randomly generated by the smartphone A, to improve connection efficiency between the smartphone C and the vehicle-mounted device B. In addition, the vehicle-mounted device B may enter the sharing mode without disconnecting the pairing connection to the smartphone A, which prevents a reconnection between the smartphone A and the vehicle-mounted device B, and prevents repeated synchronization of information stored in the vehicle-mounted device B.
Further, the management instruction MI is the sharing start instruction M11, and the transceiver module B2 may feed back device list information to the smartphone A based on the information of the smartphone C. The smartphone A may change permission information of the smart device C based on the device list information. The permission information includes management permission and/or use permission.
According to the technical solution provided in this embodiment of the present disclosure, when another device such as the smartphone C uses the vehicle-mounted device B, the permission information of the smartphone C (in other words, a device associated with the vehicle-mounted device B) may be changed (where for example, the smartphone C may be changed from having only one-time use permission to having permanent use permission, or the smartphone C may be changed from having only the one-time use permission to having permanent use permission and management permission (the smartphone C also becomes a management device of the vehicle-mounted device B)), so that leakage of information stored in the vehicle-mounted device is prevented, and sharing security is improved.
An embodiment of the present disclosure further provides a smartphone C (namely, a third device), as shown in
In the technical solution provided in this embodiment of the present disclosure, on a basis that the vehicle-mounted device B and the smartphone A establish a pairing connection, the vehicle-mounted device B is shared with the smartphone C through the smartphone A, so that the smartphone C can also use the vehicle-mounted device B, security of the vehicle-mounted device B is improved, and leakage of information stored in the vehicle-mounted device B is also prevented.
Further, the sending module C1 may determine the connection information LM based on the information of the vehicle-mounted device B. The connection information LM may include first connection information LM1 and second connection information LM2. The first connection information LM1 indicates that the smartphone C agrees to establish a sharing connection to the vehicle-mounted device B, and the second connection information LM2 indicates that the smartphone C refuses to establish the sharing connection to the vehicle-mounted device B.
In a possible implementation, when the connection information LM is the first connection information LM1, the sending module C1 sends the first connection information LM1 to the smartphone A, indicating that the smartphone C agrees to establish the sharing connection to the vehicle-mounted device B. Therefore, the sending module C1 sends a connection request to the vehicle-mounted device B.
In another possible implementation, when the connection information LM is the second connection information LM2, the sending module C1 sends the second connection information LM2 to the smartphone A, indicating that the smartphone C refuses to establish the sharing connection to the vehicle-mounted device B. In this case, the sending module C1 may not send the connection request to the vehicle-mounted device B.
As shown in
According to the control system provided in this embodiment of the present disclosure, the smartphone A can control the vehicle-mounted device B, so that security of the vehicle-mounted device B is improved.
Based on the control system CS shown in
According to the sharing system provided in this embodiment of the present disclosure, the smartphone A can control the vehicle-mounted device B, and the smartphone A further implements a sharing connection between the smartphone C and the vehicle-mounted device B, so that the smartphone C can use (or manage) the vehicle-mounted device B, and security of the vehicle-mounted device B is improved.
