[0033] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.

[0035] In the following description, reference is made to “some embodiments”, which describes a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0036] It should be pointed out that the terms "first\second\third" involved in the embodiments of the present application are used to distinguish similar or different objects, and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0037] In order to more clearly explain the service discovery method provided in the embodiments of the present application, one of the feasible application scenarios during the implementation of the method is explained below.

[0038] Figure 1 This is a schematic diagram of the application scenario provided in the embodiment of this application, please refer to Figure 1 , this scenario may include: a mobile terminal 110 and a vehicle-mounted terminal 120.

[0039] The mobile terminal 110 may include, but is not limited to, a mobile phone, a wearable device (such as a smart watch, a smart bracelet, smart glasses, etc.), a tablet computer, a laptop computer, a PC (Personal Computer), etc. The functions implemented by the method can be implemented by calling program code by a processor in the mobile terminal. Of course, the program code can be stored in a computer storage medium. Therefore, the mobile terminal includes at least a processor and a storage medium.

[0040] The vehicle-mounted terminal 120 may be an intelligent terminal provided inside the vehicle, for example, it may be a part of the vehicle computer, or it may be an independent vehicle-mounted computer device, etc., and no specific limitation is given here.

[0041] When using the vehicle-mounted terminal 120, users usually need to use it in conjunction with the mobile terminal 110. For example, the mobile terminal 110 can be used as a vehicle key, and the mobile terminal 110 can be verified through the corresponding service in the vehicle-mounted terminal 120, thereby realizing the process of starting the vehicle through the mobile terminal 110.

[0042] In addition to the above-mentioned example scenarios, in the actual implementation process, the mobile terminal 110 can also control the speakers, display, etc. on the vehicle terminal 120 to play music, videos and other media resources on the mobile terminal 110. Regardless of any of the above scenarios, information interaction between the mobile terminal 110 and the vehicle terminal 120 is required.

[0043] It should be noted that when the mobile terminal 110 and the vehicle-mounted terminal 120 interact with each other, service discovery is usually required. Service discovery means that one terminal device can discover the service on another terminal device, and one terminal device calls the service on the other terminal to implement certain functions.

[0044] For example, as explained in the above example, the music playing service on the vehicle terminal 120 can be discovered through the mobile terminal 110, and then the music playing can be realized by calling the speaker of the vehicle terminal.

[0045] Optionally, in the service discovery process in the above scenario, it is usually necessary for the mobile terminal to initiate service discovery and traverse all services in the vehicle terminal to implement the service discovery process.

[0046] In the related art, when there are too many services in the vehicle-mounted terminal, the process of service discovery by the mobile terminal may take too long, resulting in poor efficiency of service discovery.

[0047] In order to solve the above problems existing in the related art, an embodiment of the present application provides a service discovery method applied to a vehicle-mounted terminal. The following explains a feasible implementation process of the service discovery method applied to a vehicle-mounted terminal provided in an embodiment of the present application.

[0048] Figure 2 This is a flow chart of the service discovery method applied to the vehicle terminal provided in the embodiment of the present application. Please refer to Figure 2 , the method comprising:

[0049] S210: When a Bluetooth connection is established with the mobile terminal, a Bluetooth adjustment request is sent to the mobile terminal.

[0050] It should be noted that the execution subject of the method may be the above-mentioned vehicle-mounted terminal, and the mobile terminal and the vehicle-mounted terminal may establish a Bluetooth connection.

[0051] In one embodiment, the vehicle-mounted terminal can be provided with a Bluetooth module, and the mobile terminal can also be provided with a Bluetooth module. A Bluetooth connection can be established between the vehicle-mounted terminal and the mobile terminal through the corresponding Bluetooth modules. After the vehicle-mounted terminal and the mobile terminal establish a Bluetooth connection, the vehicle-mounted terminal can communicate with the mobile terminal using the Bluetooth connection, which is also Bluetooth communication.

[0052] It should be noted that the Bluetooth adjustment request may be a request instruction generated by the vehicle-mounted terminal, and the Bluetooth adjustment request is used to instruct the mobile terminal to perform Bluetooth communication according to the target time interval.

[0053] In the process of Bluetooth communication between two devices, for example, the process of Bluetooth communication between a vehicle-mounted terminal and a mobile terminal, a Bluetooth communication time interval can be set, and Bluetooth communication information interaction can be performed after each time interval.

[0054] For example, assuming that the time interval of Bluetooth communication is 60 ms, Bluetooth communication between two devices can be achieved once every 60 ms, thereby realizing information interaction during the Bluetooth communication process.

[0055] In one embodiment, the target time interval may be smaller than a preset upper limit of the time interval, wherein the preset upper limit of the time interval may be an upper limit of the time interval for Bluetooth communication under normal circumstances.

[0056] For example, assuming that the Bluetooth communication time interval is usually 45ms, the preset time interval upper limit may be 45ms, or may be a time interval less than 45ms, such as 30ms, etc. The target time interval may be less than the preset time interval upper limit.

[0057] In one embodiment, the target time interval includes: a minimum time interval specified in the Bluetooth communication protocol.

[0058] It should be noted that the minimum time interval specified in the Bluetooth communication protocol may be 7.5 ms. In actual implementation, the target time interval may also be set to 7.5 ms.

[0059] Optionally, in the actual implementation process, the time interval of Bluetooth communication may be limited by the device's own capabilities. For example, if the shortest time interval of Bluetooth communication that a mobile terminal can support is 15ms, then the target time interval can also be 15ms. No specific restriction is made here, as long as it is less than the above-mentioned preset time interval upper limit.

[0060] It should be noted that the shorter the time interval of Bluetooth communication is, the more times Bluetooth communication is performed in the same time period, and accordingly, more information can be transmitted through Bluetooth communication.

[0061] Optionally, after the vehicle-mounted terminal and the mobile terminal establish a Bluetooth communication connection, the mobile terminal can be asked to shorten the Bluetooth communication time interval by sending a Bluetooth adjustment request, that is, the mobile terminal can use high-frequency Bluetooth communication to realize Bluetooth communication between the mobile terminal and the vehicle-mounted terminal.

[0062] For example, the Bluetooth module of the vehicle terminal may generate a Bluetooth adjustment request, such as the LL_CONNECTION_UPDATE_REQ instruction, which may request the mobile terminal to set the connection interval to a target time interval, such as 7.5 ms.

[0063] S220: When the mobile terminal performs Bluetooth communication according to the target time interval, a service discovery request sent by the mobile terminal is received, and the mobile terminal is enabled to perform service discovery based on the service discovery request.

[0064] It should be noted that after receiving the above Bluetooth adjustment request, the mobile terminal can adjust its own Bluetooth communication time interval. After adjusting to the target time interval, high-frequency communication between the mobile terminal and the vehicle-mounted terminal can be achieved.

[0065] Correspondingly, the vehicle-mounted terminal also needs to adjust its own Bluetooth communication time interval to adapt to the mobile terminal. When both the mobile terminal and the vehicle-mounted terminal perform Bluetooth communication according to the target time interval, the above-mentioned high-frequency communication can be achieved, and the high-frequency communication can specifically be high-frequency Bluetooth communication.

[0066] In one embodiment, when the mobile terminal performs Bluetooth communication at a target time interval, high-frequency Bluetooth communication between the mobile terminal and the vehicle-mounted terminal can be achieved. In this case, the mobile terminal can send a service discovery request to the vehicle-mounted terminal, wherein the service discovery request can be, for example, a GATT_DiscoverPrimaryServices instruction. Various services on the vehicle-mounted terminal can be discovered through the service discovery request, for example: the service list of the vehicle-mounted terminal can be accessed, which can include service lists of various protocols.

[0067] For example: ICCOA (Intelligent Car Connectivity Open Alliance), CCC (Car Connectivity Consortium), ICCE (Intelligent Car Connectivity Ecosystem Alliance), iBeacon (indoor positioning system based on Bluetooth low energy technology) or other types of service lists corresponding to private protocols, without specific limitation here.

[0068] It should be noted that after receiving the above-mentioned service discovery request, the vehicle-mounted terminal can realize the service discovery of the vehicle-mounted terminal by the mobile terminal. During the service discovery process, for example, the mobile terminal can traverse each service of the vehicle-mounted terminal and obtain the service, thereby obtaining the function list therein. In addition, the identity, authority and various attributes of each service can be parsed, thereby realizing the above-mentioned service discovery process.

[0069] It should be noted that performing Bluetooth communication according to the target time interval to realize the service discovery process can shorten the time consumed by the service discovery process and complete the service discovery process more quickly, avoiding the problem of poor service discovery efficiency caused by the service discovery process taking too long.

[0070] In the service discovery method provided in the embodiment of the present application, when a Bluetooth connection is established with a mobile terminal, the vehicle-mounted terminal can send a Bluetooth adjustment request to the mobile terminal, and the Bluetooth adjustment request is used to instruct the mobile terminal to perform Bluetooth communication according to a target time interval, and the target time interval is less than or equal to the upper limit of the preset time interval; when the mobile terminal performs Bluetooth communication according to the target time interval, the vehicle-mounted terminal receives the service discovery request sent by the mobile terminal, and based on the service discovery request, enables the mobile terminal to perform service discovery. Among them, since the target time interval is less than the upper limit of the preset time interval, the mobile terminal can perform service discovery according to a shorter time interval. In the process of performing service discovery according to a shorter time interval, service discovery can be performed at a faster speed, which shortens the time consumed by service discovery and improves the efficiency of service discovery.

[0071] The following explains another feasible implementation process of the service discovery method applied to the vehicle terminal provided in the embodiment of the present application.

[0072] Figure 3 This is another flow chart of the service discovery method applied to the vehicle terminal provided in the embodiment of the present application. Figure 3 Before sending the Bluetooth adjustment request to the mobile terminal, the method further includes:

[0073] S310: Acquire device communication information of the mobile terminal.

[0074] In one embodiment, the device communication information of the mobile terminal may be obtained after the mobile terminal and the vehicle-mounted terminal establish Bluetooth communication. For example, after the two establish Bluetooth communication, they may transmit their own device communication information to the other device.

[0075] The vehicle-mounted terminal may send the device communication information of the vehicle-mounted terminal to the mobile terminal, and the mobile terminal may send the device communication information of the mobile terminal to the vehicle-mounted terminal.

[0076] Alternatively, these device communication information can also be configured in the broadcast. For example, the vehicle-mounted terminal can broadcast its own device communication information during the broadcast process, that is, the device communication information of the vehicle-mounted terminal. When the mobile terminal receives the broadcast information and returns the Bluetooth establishment request, it can carry its own device communication information, that is, the device communication information of the mobile terminal.

[0077] It should be noted that for some device communication information, the vehicle terminal and the mobile terminal can be the same. For such device communication information, it does not need to be obtained from the other device, and the relevant device communication information of the own can be obtained, for example: relevant information for Bluetooth communication.

[0078] In one embodiment, the device communication information includes at least one of the following: a current Bluetooth communication time interval or a device connection requirement.

[0079] It should be noted that the current Bluetooth communication time interval can be the same information in the vehicle terminal and the mobile terminal in the above-mentioned device communication information. For example: the vehicle terminal and the mobile terminal can work according to the same Bluetooth communication time interval during the Bluetooth communication process. The current Bluetooth communication time interval can be the time interval for information exchange between the two during the Bluetooth communication process. The device communication information also exists in the vehicle terminal, and the vehicle terminal's own Bluetooth communication time interval can be directly obtained.

[0080] The device connection requirement can be a function that the device can perform after establishing Bluetooth communication. For example: if the mobile terminal needs to perform service discovery on the vehicle terminal, a corresponding indication can be made in the device connection requirement; correspondingly, if the mobile terminal does not need to perform service discovery on the vehicle terminal, a corresponding indication can also be made in the device connection requirement.

[0081] The device connection requirement may be sent by the mobile terminal to the vehicle-mounted terminal.

[0082] Accordingly, a Bluetooth adjustment request is sent to the mobile terminal, including:

[0083] S320: When the device communication information meets the target condition, a Bluetooth adjustment request is sent to the mobile terminal.

[0084] It should be noted that after the vehicle-mounted terminal obtains the above-mentioned device communication information, it can determine whether each type of device communication information meets its corresponding target condition, and different target conditions can be configured for different device communication information.

[0085] If the corresponding target condition is met, a Bluetooth adjustment request may be sent to the mobile terminal; if the corresponding target condition is not met, no Bluetooth adjustment request may be sent to the mobile terminal.

[0086] In one embodiment, when the device communication information meets the target condition, sending a Bluetooth adjustment request to the mobile terminal includes: when the current Bluetooth communication time interval is greater than the target time interval, sending the Bluetooth adjustment request to the mobile terminal.

[0087] It should be noted that if the current Bluetooth communication time interval is greater than the target time interval, it can be determined that the current Bluetooth communication time interval is longer and Bluetooth communication is not performed at a shorter time interval. Therefore, a Bluetooth adjustment request can be sent to the mobile terminal to allow the mobile terminal to adjust its own Bluetooth communication time interval to the target time interval.

[0088] In contrast, if the current Bluetooth communication time interval is less than or equal to the target time interval, it can be determined that the current Bluetooth communication time interval is shorter and Bluetooth communication is already performed at a shorter time interval, so there is no need to send a Bluetooth adjustment request to the mobile terminal.

[0089] In one embodiment, when the device communication information meets the target condition, sending a Bluetooth adjustment request to the mobile terminal includes: when the device connection requirement indicates that the mobile terminal needs to perform service discovery, sending a Bluetooth adjustment request to the mobile terminal.

[0090] It should be noted that if the device connection requirement indicates that the mobile terminal needs to perform service discovery, it can be determined that the mobile terminal has a need to perform service discovery. If service discovery is required, the Bluetooth communication time interval needs to be adjusted. Therefore, a Bluetooth adjustment request can be sent to the mobile terminal, so that the mobile terminal can adjust its own Bluetooth communication time interval to the target time interval.

[0091] Conversely, if the device connection requirement indicates that the mobile terminal does not need to perform service discovery, it can be determined that the mobile terminal does not need to perform service discovery, that is, the mobile terminal does not need to perform service discovery after establishing a Bluetooth connection, and there is no need to adjust the Bluetooth communication time interval. Therefore, there is no need to send a Bluetooth adjustment request to the mobile terminal.

[0092] It should be noted that the above two conditions are only feasible examples. In the actual implementation process, other conditions can also be set, and no specific restrictions are made here.

[0093] Optionally, for the above two conditions, the Bluetooth adjustment request can be sent when any one of the conditions is met, or the Bluetooth adjustment request can be sent when both of the above conditions are met. There is no specific limitation here and it can be set based on actual needs.

[0094] In the service discovery method provided in the embodiment of the present application, the device communication information of the mobile terminal can be obtained, and when the device communication information meets the target conditions, a Bluetooth adjustment request can be sent to the mobile terminal. For example, when the time interval of the current Bluetooth communication is greater than the target time interval, a Bluetooth adjustment request can be sent to the mobile terminal; or, when the device connection requirement indicates that the mobile terminal needs to perform service discovery, a Bluetooth adjustment request can be sent to the mobile terminal. By setting different target conditions, a judgment can be made in advance to avoid sending the corresponding Bluetooth adjustment request when the mobile terminal does not need to perform service discovery, and the sending of the Bluetooth adjustment request can be implemented under specific conditions.

[0095] The following explains another feasible implementation process of the service discovery method based on the vehicle terminal provided in the embodiment of the present application.

[0096] Figure 4 This is another flow chart of the service discovery method applied to the vehicle terminal provided in the embodiment of the present application. Please refer to Figure 4 After the mobile terminal performs service discovery based on the service discovery request, the method further includes:

[0097] S410: When the features of all services of the vehicle terminal are traversed, or when the execution time of the service discovery exceeds a preset time threshold, it is determined that the service discovery is completed.

[0098] It should be noted that, during the process of the mobile terminal discovering services in the vehicle-mounted terminal, the service discovery process may be determined to be completed after certain conditions are met.

[0099] Among them, it can include active completion and passive completion. Among them, active completion can be that the mobile terminal can determine that the service discovery process has been completed when traversing the characteristics of all services of the vehicle terminal. In this case, active completion of service discovery can be achieved.

[0100] Passive completion may be due to some external factors that require stopping service discovery. For example, if the mobile terminal and the vehicle terminal are in communication at the target time interval for a long time, the frequency of Bluetooth signal interference may increase. In addition, if they are in high-frequency communication for a long time, the power consumption of the mobile terminal and the vehicle terminal will be high, which will cause other Bluetooth communications to be stuck.

[0101] For example, if a mobile terminal is simultaneously performing two Bluetooth communication processes, service discovery and music playback on a Bluetooth headset, and if communications are performed at the target time interval for a long time, it may cause freezes in the Bluetooth headset during music playback.

[0102] To avoid this situation, the service discovery time can be limited. For example, the service discovery time limit can be set to 500ms. After more than 500ms, it can be determined that the service discovery is completed. This process can be a case of passive completion as mentioned above.

[0103] It should be noted that the service discovery process can be ended whether it is completed actively or passively.

[0104] In the service discovery method provided in the embodiment of the present application, service discovery can be determined to be complete when the characteristics of all services of the vehicle terminal are traversed, or when the execution time of service discovery exceeds a preset time threshold. In particular, the service discovery step can be completed quickly by actively or passively completing it, thereby reducing the negative impact of high-frequency Bluetooth communication.

[0105] The following specifically explains one feasible implementation process of restoring Bluetooth communication after service discovery is completed, as provided in an embodiment of the present application.

[0106] Figure 5 This is a flow chart of the time interval recovery process for Bluetooth communication in the service discovery method provided in the embodiment of the present application. Figure 5 ,

[0107] After enabling the mobile terminal to perform service discovery based on the service discovery request, the method further includes:

[0108] S510: When the service discovery is completed, a Bluetooth recovery request is sent to the mobile terminal.

[0109] In one embodiment, if the service discovery is completed, the vehicle-mounted terminal may send a Bluetooth recovery request to the mobile terminal, where the Bluetooth recovery request is used to instruct the mobile terminal to perform Bluetooth communication according to a preset upper limit of the time interval.

[0110] For example, during the service discovery process, a target time interval may be used for service discovery, such as 7.5ms. After the service discovery is completed, the normal time interval of Bluetooth communication may be restored, that is, the preset time interval upper limit, such as 45ms.

[0111] It should be noted that the process of Bluetooth communication between the vehicle terminal and the mobile terminal at the target time interval is a high-frequency communication process, which can realize rapid data transmission under Bluetooth communication, but may cause high power consumption, multiple interferences and other Bluetooth function freezes and other problems. Therefore, Bluetooth communication cannot be carried out at the target time interval for a long time.

[0112] The process of Bluetooth communication between the vehicle terminal and the mobile terminal at the preset time interval is a medium-low frequency communication process, and the data transmission speed is slow, but it does not cause high power consumption, multiple interferences and other Bluetooth function jamming problems. Under normal circumstances, Bluetooth communication can be carried out according to the preset time interval.

[0113] It should be noted that after determining that the service discovery is completed, a Bluetooth recovery request may be sent to the mobile terminal to restore normal Bluetooth communication and avoid the negative impact of high-frequency communication.

[0114] In the service discovery method provided in the embodiment of the present application, a Bluetooth recovery request can be sent to the mobile terminal when service discovery is complete. When service discovery is no longer necessary, high-frequency Bluetooth communication can be promptly restored to medium- and low-frequency Bluetooth communication, thereby reducing the negative impact of high-frequency Bluetooth communication and ensuring rapid service discovery while minimizing negative impacts.

[0115] The following explains another feasible implementation process of the service discovery method provided in the embodiment of the present application.

[0116] Figure 6 This is a flow chart of Bluetooth broadcasting in the service discovery method provided in the embodiment of this application. Please refer to Figure 6 Before establishing a Bluetooth connection with the mobile terminal, the method further includes:

[0117] S610: Broadcasting a Bluetooth connection establishment request in a targeted Bluetooth broadcast mode.

[0118] It should be noted that in related technologies, in order to establish Bluetooth connections between different devices, the vehicle terminal usually performs Bluetooth broadcast polling in two different ways. For example, one broadcast can be performed using Android's Bluetooth broadcast method; another broadcast can be performed using Apple's Bluetooth broadcast method.

[0119] This method will cause the vehicle terminal to frequently switch the Bluetooth broadcast mode.

[0120] In the embodiment of the present application, a target Bluetooth broadcast mode may be used for broadcasting, wherein the target Bluetooth broadcast mode is the Bluetooth broadcast mode used by the mobile terminal in the historical connection record.

[0121] For example, if the mobile terminal uses the Android Bluetooth broadcast mode for Bluetooth communication in the historical records, the Android Bluetooth broadcast mode may be used to broadcast the Bluetooth connection establishment request.

[0122] S620: Receive the response connection request sent by the mobile terminal, and establish a Bluetooth connection with the mobile terminal.

[0123] It should be noted that after the Bluetooth connection establishment request is sent, when the mobile terminal enters the corresponding broadcast range, it can receive the Bluetooth connection establishment request, and then respond based on the Bluetooth connection establishment request, reply to the response connection request, and after the vehicle terminal receives the response connection request, it can establish a Bluetooth connection between the vehicle terminal and the mobile terminal.

[0124] In the service discovery method provided in the embodiments of the present application, a target Bluetooth broadcast mode can be used to broadcast a Bluetooth connection establishment request; a response connection request sent by a mobile terminal is received, and a Bluetooth connection with the mobile terminal is established. The target Bluetooth broadcast mode is the Bluetooth broadcast mode used by the mobile terminal in the historical connection record. By using the target Bluetooth mode to broadcast the Bluetooth establishment request, the frequency of broadcast switching of the vehicle terminal can be reduced, thereby reducing the power consumption of the vehicle terminal.

[0125] The following explains the service discovery method applied to the vehicle terminal provided in the embodiment of the present application through an overall process relationship.

[0126] Figure 7 This is a schematic diagram of the overall process of the service discovery method applied to the vehicle terminal provided in the embodiment of the present application. Please refer to Figure 7 , during the implementation of this method:

[0127] After the mobile terminal initiates a request to establish a Bluetooth connection with the vehicle-mounted terminal, it can first determine whether the Bluetooth communication is established successfully. If not, it can be determined that the connection failed and the process is ended; if so, the vehicle-mounted terminal can send a Bluetooth adjustment request to the mobile terminal, and the time interval of the Bluetooth communication between the two can be adjusted to the target time interval, and then the mobile terminal can enter the high-frequency Bluetooth communication mode according to the target time interval. If it does not enter, service discovery can be performed according to the preset time interval upper limit; if it enters, service discovery can be performed, and after the service discovery is completed, the Bluetooth recovery request can be used to resume Bluetooth communication according to the preset time interval upper limit, and then the process can be ended.

[0128] The above are all service discovery methods implemented when the vehicle-mounted terminal is the execution subject. The following explains the service discovery method implemented when the execution subject is not a mobile terminal.

[0129] Figure 8For a flow chart of the service discovery method applied to a mobile terminal provided in an embodiment of the present application, please refer to Figure 8 , the method comprising:

[0130] S810: When a Bluetooth connection is established with the vehicle-mounted terminal, a Bluetooth adjustment request sent by the vehicle-mounted terminal is received.

[0131] It should be noted that the execution subject of the method may be the above-mentioned mobile terminal, which may receive a Bluetooth adjustment request sent by the vehicle-mounted terminal when a Bluetooth connection is established with the vehicle-mounted terminal.

[0132] In one embodiment, the vehicle-mounted terminal can be provided with a Bluetooth module, and the mobile terminal can also be provided with a Bluetooth module. A Bluetooth connection can be established between the vehicle-mounted terminal and the mobile terminal through the corresponding Bluetooth modules. After the vehicle-mounted terminal and the mobile terminal establish a Bluetooth connection, the vehicle-mounted terminal can communicate with the mobile terminal using the Bluetooth connection, which is also Bluetooth communication.

[0133] It should be noted that the Bluetooth adjustment request may be a request instruction generated by the vehicle-mounted terminal, and the Bluetooth adjustment request is used to instruct the mobile terminal to perform Bluetooth communication according to the target time interval.

[0134] S820: Based on the Bluetooth adjustment request, perform Bluetooth communication with the vehicle terminal at a target time interval, and send a service discovery request to the vehicle terminal for service discovery.

[0135] It should be noted that the mobile terminal can perform Bluetooth communication with the vehicle-mounted terminal at a target time interval based on the Bluetooth adjustment request, and can perform corresponding service discovery work by sending a service discovery request.

[0136] In one embodiment, the target time interval includes: a minimum time interval specified in the Bluetooth communication protocol.

[0137] In the service discovery method provided in the embodiment of the present application, a Bluetooth adjustment request sent by the vehicle-mounted terminal can be received while a Bluetooth connection is established with the vehicle-mounted terminal; based on the Bluetooth adjustment request, Bluetooth communication is performed with the vehicle-mounted terminal at a target time interval, and a service discovery request is sent to the vehicle-mounted terminal to perform service discovery. Since the target time interval is less than the preset time interval upper limit, the mobile terminal can perform service discovery at a shorter time interval. During the process of performing service discovery at a shorter time interval, service discovery can be performed at a faster speed, thereby shortening the time consumed by service discovery and improving the efficiency of service discovery.

[0138] The following explains one feasible implementation process of data interaction between the mobile terminal and the vehicle-mounted terminal in the embodiment of the present application from the perspective of data interaction.

[0139] Figure 9 For a schematic diagram of the interaction between the mobile terminal and the vehicle terminal provided in the embodiment of the present application, please refer to Figure 9 , the method comprising:

[0140] S910: When the Bluetooth connection is established, the vehicle-mounted terminal sends a Bluetooth adjustment request to the mobile terminal.

[0141] S920: The mobile terminal performs Bluetooth communication with the vehicle-mounted terminal at a target time interval based on the Bluetooth adjustment request.

[0142] S930: The mobile terminal sends a service discovery request to the vehicle terminal.

[0143] S940: The mobile terminal performs service discovery.

[0144] It should be noted that the specific implementation process of the above steps S910-S940 has been explained above and will not be repeated here.
