In related Bluetooth technology, there are three levels of commonly used transmit power and three levels of range. But this is not adjustable and is determined by the manufacturer when producing the product. In other words, if the product is 1mW, it will always have this power. It is impossible to increase the power because the user wants to expand the range, or to reduce the power due to power consumption and narrow the range. It cannot be done. Flexible adjustment cannot optimize the internal current of the terminal device during Bluetooth operation, resulting in high power consumption of the terminal device.

The method embodiments provided by the embodiments of the present disclosure can be executed in a mobile terminal, a computer terminal, a server, a digital device, or a similar computing device. Taking running on a mobile terminal as an example, FIG. 1 is a hardware structure block diagram of a mobile terminal to which a Bluetooth power adjustment method according to an embodiment of the present disclosure is applied. As shown in FIG. 1, the mobile terminal may include one or more (only one is shown in FIG. 1) processors 102 (the processor 102 may include but is not limited to a microprocessor MCU or may Programming logic device (FPGA, etc.) and a memory 104 for storing data. In an exemplary embodiment, the above-mentioned mobile terminal may also include a transmission device 106 and an input and output device 108 for communication functions. Persons of ordinary skill in the art can understand that the structure shown in Figure 1 is only illustrative, and it does not limit the structure of the above-mentioned mobile terminal. For example, the mobile terminal may also include more or fewer components than shown in FIG. 1 , or have a different configuration than shown in FIG. 1 .

The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the Bluetooth power adjustment method in the embodiment of the present disclosure. The processor 102 executes the computer program by running the computer program stored in the memory 104. Various functional applications and data processing implement the above methods. Memory 104 may include high-speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include memory located remotely relative to the processor 102, and these remote memories may be connected to the mobile terminal 10 through a network. Examples of the above-mentioned networks include but are not limited to the Internet, intranets, local area networks, mobile communication networks and combinations thereof.

The transmission device 106 is used to receive or send data via a network. The above-mentioned network examples may include a wireless network provided by a communication provider of the mobile terminal 10 . In one example, the transmission device 106 includes a network adapter (Network Interface Controller, NIC for short), which can be connected to other network devices through a base station to communicate with the Internet. In one example, the transmission device 106 may be a radio frequency (Radio Frequency, RF for short) module, which is used to communicate with the Internet wirelessly.

The Bluetooth power adjustment method provided by the embodiment of the present disclosure can be run on a terminal device. The terminal device is configured with a Bluetooth module. The Bluetooth module consists of a wireless transceiver (RF), a baseband controller (BB) of the Bluetooth protocol stack. ) and link management layer (LMP), in which the wireless transceiver is configured with an antenna port. During implementation, the system-on-chip technology SOC (System-On-Chip) can be used to embed these three layers of functional modules in the same chip. It mainly consists of microprocessor (CPU), wireless transceiver (RF), baseband controller (BB), static random access memory (SRAM), flash memory (Flash program memory), universal asynchronous receiver-receiver (UART), universal serial It is composed of interface (USB), voice coder/decoder (CODEC) and Bluetooth test module.

In related Bluetooth technology, usually, a terminal device can only connect to one access device for Bluetooth communication. To address this problem, embodiments of the present disclosure provide a solution, using Bluetooth MIMO (multiple-in multipleout, multiple-in, multiple-out) technology, that is, adding Bluetooth channels to the circuit design and antenna design of the terminal device, thereby realizing a terminal The device can communicate via Bluetooth with multiple access devices. In detail, as shown in Figure 2, according to the relevant platform capabilities, for the configuration circuit design of the Bluetooth MIMO mode, the embodiment of the present disclosure mainly uses a set of baseband controller (BB) + multiple sets of wireless transceivers (RF) +Multiple antenna ports. At least two groups of wireless transceivers are connected to the baseband controller; and each group of wireless transceivers is connected to a wireless port in one-to-one correspondence; where different groups of wireless transceivers and wireless ports are used to establish a connection between terminal equipment and different access devices. Bluetooth connection between; and the terminal device through each set of wireless transceivers infrared and antenna When the line port performs Bluetooth communication with each access device, it selects the Bluetooth protocol and the transmission parameters corresponding to the Bluetooth protocol from at least one Bluetooth protocol and the transmission parameters corresponding to each Bluetooth protocol to work.

As for the audio sharing part, multiple audio circuits can be designed to complete the functions of the sharing part. During implementation, the audio circuits can be set in one-to-one correspondence with the wireless transceiver. When designing an antenna, the selection and layout are based on the actual number of channels used. The layout and antenna design will not be described in detail here.

Through the above hardware circuit, Bluetooth MIMO technology can be implemented. MIMO technology refers to a technology that can exponentially increase the capacity and spectrum utilization of communication systems without increasing bandwidth. MIMO technology can be defined as the existence of multiple independent channels between the transmitter and the receiver, which means that there is sufficient spacing between antenna units. Therefore, the correlation of signals between antennas is eliminated, the link performance of the signal is improved, and the data throughput. According to the design of WIFI MIMO technology, Bluetooth MIMO technology can also achieve the same link design. For all wireless communication systems, whether it is a mobile wireless network like 3GPP UMTS or a wireless local area network like WLAN, in addition to high-speed In addition to traditional methods such as order modulation or larger signal bandwidth to increase data rates, multi-antenna technology can also be used to increase channel capacity.

At the same time, in terms of the selection of transceiver methods, there is no need to fix or specify a channel to transmit or receive at the same time. Choosing a certain channel as the transmitting working state or the receiving working state mainly depends on the user's working scenario of using Bluetooth and the status of the antenna. , the power consumption of terminal equipment, etc. Moreover, based on the above implementation methods of the relevant embodiments of the present disclosure, corresponding diversity methods can also be used in the wireless system according to different transmission channel types. The main related diversity methods include: time diversity (different time slots and channel coding), frequency diversity (different channels, spreading and OFDM), and space diversity. Multi-antenna systems utilize spatial methods, and MIMO, as a typical multi-antenna system, can significantly increase the transmission rate. In actual wireless systems, one or more diversity methods can be used according to actual conditions. In the embodiment of the present disclosure, the Bluetooth solution uses multiple transceiver modes to work together or in combination. At the same time, one or more transceiver modes are enabled according to the status and number of access devices to perform multi-application allocation operations. Method: When the number of threads is small, use separate transceiver mode and enable SISO (simple input simple output) mode. When the number of threads increases or when content needs to be shared, multiple transceiver modes can be enabled. Enable MIMO mode to share task content and threads, increasing Bluetooth throughput and user experience.

In the embodiment of the present disclosure, by adding Bluetooth channels to the terminal device, establishing a Bluetooth MIMO mode, and using multiple channels to transmit and receive at the same time, the number of access devices and the throughput rate are increased, and different types of Bluetooth devices can be connected in different categories. to different Bluetooth channels, so that each function will not interfere with each other and can operate normally; at the same time, in the selection of transceiver methods, there is no need to fix or specify a channel to transmit or receive at the same time, and the channel function selection method is completely free. This enhances the overall user experience. Moreover, when users use terminal equipment, if the antenna is blocked or fails, they can also switch to other channels to ensure that the efficiency of the antenna will not cause disconnection or noise or intermittent sound during use. Wait for phenomena that affect user experience to occur.

Embodiments of the present disclosure also provide a Bluetooth power adjustment method. The Bluetooth power adjustment method can be applied to the above-mentioned terminal device. The terminal device is configured with at least one Bluetooth protocol and corresponding transmission parameters for each Bluetooth protocol. ; Wherein, the transmission parameters at least include: at least one transmission level, and at least one transmission power corresponding to each transmission level. Preferably, the terminal device is configured with: at least two Bluetooth protocols, the transmission levels corresponding to each Bluetooth protocol are greater than or equal to 2, and the transmission power corresponding to each transmission level is greater than or equal to 2.

During implementation, at least one Bluetooth protocol and the corresponding transmission parameters of each Bluetooth protocol can be configured in the storage module of the terminal device, or can be configured in the microprocessor, baseband controller or at least two sets of wireless transceivers of the terminal device. in the server; it can also be configured in the terminal device in the form of a hardware configuration file, which is not limited here.

For further understanding, the embodiment of the present disclosure takes a hardware configuration file as an example for description. The hardware configuration file includes: Bluetooth chip channel activation status, Bluetooth chip power settings, Bluetooth protocol mode settings, Bluetooth receiving RSSI parameter settings, and other settings of the Bluetooth chip; the embodiments of this disclosure focus on: the Bluetooth chip channel Activation status, Bluetooth chip’s transmission power and transmission level settings, and Bluetooth chip’s protocol mode settings. Among them, the most important thing to pay attention to is the transmission power and transmission level settings of the Bluetooth chip, and the protocol mode setting of the Bluetooth chip.

The transmission format and transmission power of relevant Bluetooth chips are in one-to-one correspondence. According to relevant protocols, the power levels of traditional Bluetooth technology are divided into Class1, Class2, and Class3. The power of each level is different. Although there are overlaps, the intervals are different. to ensure that its test indicators can meet relevant requirements. At the same time, in the traditional Bluetooth protocol, the transmission power configured for different transmission levels is unchanged, and it maintains one channel and is unique.

In the embodiment of the present disclosure, the transmission power configured for each Bluetooth protocol (different Bluetooth protocols correspond to the transmission formats of different Bluetooth chips) is not unique, but is configured in an array mode, based on the calling requirements and whether Bluetooth is enabled. MIMO, adjust the transmission level, extract the corresponding transmission power value, and map it to the Bluetooth chip transmission format configuration. This can make the transmission power configuration in each transmission format selectable, providing both automatic and manual setting adjustments for subsequent The implementation of this model provides an important foundation.

During implementation, in the embodiment of the present disclosure, the hardware configuration file mainly focuses on parameters such as Bluetooth protocol version, transmission power, and transmission level. Among them, for each Bluetooth protocol version, there are multiple transmission levels, and the transmission power corresponding to each transmission level is also a set of values, not a unique value.

For ease of understanding, here is an example. In the hardware configuration file, there are three Bluetooth protocol versions: Bluetooth protocol version A, Bluetooth protocol version B and Bluetooth protocol version C. Among them, each Bluetooth protocol version has three emission levels, each The emission levels have different transmission power ranges. Within the respective transmission power ranges, the transmission power range can be divided into a set of values at preset power intervals, such as 1dBm. Each value in the set of values can be used as Transmit power. Taking Bluetooth protocol version A as an example, Table 1 shows the correspondence between parameters such as Bluetooth protocol version A, transmission level, and transmission power. For an understanding of other Bluetooth protocol versions, please refer to Bluetooth protocol version A.

Table 1 Illustration of Bluetooth protocol version A in the hardware configuration file

Among them, the beginning and end numbers of the transmission power array corresponding to each transmission level are pre-configured, and the power interval is set to determine the available transmission power. In addition, the hardware configuration file can also include: emission level calibration parameters corresponding to each Bluetooth protocol version. The main function of this parameter is to determine which emission level the circuit is configured at, and what the amplification level is. During implementation, The emission level calibration parameters are also an array.

In practical applications, the appropriate transmission power and transmission level calibration parameters can be selected according to the actual situation, so that the transmission parameters can be flexibly adjusted and optimized to reduce the internal transmission current and release some resources to reduce the power consumption of the entire terminal equipment. Purpose.

A Bluetooth power adjustment method provided by an embodiment of the present disclosure will be described below with reference to FIG. 3 . The Bluetooth power adjustment method is suitable for terminal equipment. The terminal equipment is configured with at least one Bluetooth protocol and corresponding transmission parameters for each Bluetooth protocol. As shown in Figure 3, the Bluetooth power adjustment method includes the following steps.

Step 301: Obtain the current working parameters of the access device and the terminal device; where the access device is a device that establishes Bluetooth communication with the terminal device.

Among them, the working parameters mainly include two categories: hardware-side indicator parameter values and software-side indicator parameter values. Among them, the function of the hardware side indicators is to analyze and judge the hardware indicators of the terminal equipment that is responsible for the connection function using traditional Bluetooth technology. Among them, the main indicators on the hardware side include bit error rate, EVM (Error Vector Magnitude), reception Sensitivity, throughput rate, etc., and the reference standard tables are documents related to indicator thresholds in 3GPP and BT SIG alliance standards. The standard table can be stored in the memory of the terminal device or in the microprocessor in advance. The standard table stores the above Standard preset threshold values for each indicator. When starting the hardware-side indicator analysis system part, the standard table is directly called for analysis and judgment, so that the target Bluetooth protocol and target transmission parameters can be selected based on the judgment results.

For the software-side indicators, the main function is to analyze and judge the relevant indicators and request application types reported by the access device paired with the terminal device Bluetooth. Among them, the indicators include: receiving sensitivity, throughput rate, bit error rate, request application Type, MIMO antenna status, traffic statistics, etc. The request application type mainly includes: data transmission, audio sharing, multi-device connection, separate transmission and other interactive types. Similarly, the reference standard tables are documents related to indicator thresholds in the 3GPP and BT SIG protocols. The standard tables are pre-stored in the memory of the terminal device or in the microprocessor. The standard tables store the standard preset thresholds for each of the above indicators. limit. Through the above indicators, we can analyze what type of interaction the access device and the terminal device mainly carry out, whether operations that require high resource maintenance for a long time, etc.

By comparing the hardware-side indicators and software-side indicators with the parameters in the standard table, the working status of the access equipment and terminal equipment is determined, and the judgment results are obtained. Based on the judgment results, it is determined which Bluetooth protocol and transmission parameters are selected for subsequent development. Do the work.

Step 302: Select the target Bluetooth protocol and the target transmission parameters from at least one Bluetooth protocol and the corresponding transmission parameters of each Bluetooth protocol according to the current working parameters.

Step 303: The terminal device and the access device conduct Bluetooth communication according to the target Bluetooth protocol and target transmission parameters.

In the embodiment of the present disclosure, by monitoring the current working parameters of the access device and the terminal device, and promptly adjusting the Bluetooth protocol and transmission parameters used when the access device and the terminal device communicate, dynamic configuration of Bluetooth transmission parameters is achieved, so that The current of the terminal device can be dynamically adjusted, thereby optimizing the internal current generated when the terminal device is working via Bluetooth and optimizing the resources of the terminal device, thereby reducing the probability of the terminal device working at high current and saving power consumption to a certain extent.

When the terminal device works in the Bluetooth multiple-input multiple-output MIMO mode and the terminal device communicates with multiple access devices via Bluetooth, for each access device and terminal device, the current working parameters of the access device and terminal device are obtained; according to the current The working parameters include selecting the target Bluetooth protocol and the target transmission parameters from at least one Bluetooth protocol and the corresponding transmission parameters of each Bluetooth protocol; the terminal device and the access device conduct Bluetooth communication according to the target Bluetooth protocol and the target transmission parameters.

Among them, the target Bluetooth protocol and target transmission parameters used for Bluetooth communication between different access devices and terminal devices may be the same or different.

When a terminal device uses MIMO technology to implement a Bluetooth module, multiple devices can be accessed and work together, and at the same time, the power consumption of the overall terminal device can be reduced.

Among them, in the embodiment of the present disclosure, there are two main methods for selecting the target Bluetooth protocol and target transmission parameters: automatic setting and adjustment and manual setting and adjustment.

The first adjustment method is automatic setting adjustment.

The automatic setting adjustment part is responsible for adjusting the transmission parameters and hardware status (transmitting working status or receiving working status) in the hardware configuration file in real time based on the above judgment results when the traditional Bluetooth pairing of the terminal device is turned on, and configuring the hardware circuit part. And maintain the optimized parameters and hardware status in the hardware configuration file, while counting the data traffic used by the access device. Once the set conditions and thresholds are exceeded, the alarm mechanism is activated and the Bluetooth transmission work or other programs are ended. On the interface of the terminal device Display information and wait for the user's next action.

For the automatic setting adjustment part, when the access device establishes Bluetooth communication with the terminal device, it can perform Bluetooth communication according to the initial Bluetooth protocol and initial transmission parameters. Among them, in order to reduce power consumption, when configuring the initial Bluetooth protocol and initial transmission parameters, the Bluetooth transmission format and Bluetooth transmission parameters with relatively small power consumption can be used to reduce power consumption in the early stage of operation. In addition, after the access device and the terminal device are paired, the number of access devices connected to the terminal device via Bluetooth can also be counted, and the initial Bluetooth protocol and initial transmission parameters can be determined based on the number of access devices. If the number of accessed devices is relatively small, for example, less than the preset number, you can select the appropriate initial Bluetooth protocol and initial transmission parameters when the traffic is relatively small. If the number is relatively large (greater than or equal to the preset number), in order to ensure Bluetooth communication performance, you can choose larger traffic The initial Bluetooth protocol and initial transmission parameters are suitable for the case.

The terminal device and the access device conduct Bluetooth communication according to the initial Bluetooth protocol and initial transmission parameters. That is, after the access device successfully connects to the terminal device, the access device can communicate according to the actual current working parameters of the access device, such as: request application type, traffic estimation and Receiving status and other parameters determine the working status of access equipment and terminal equipment to enable the optimization of the number of radio frequency channels in the hardware configuration file, optimize the corresponding transmission protocol selection, power level, transmission power configuration, etc., and maintain the optimized parameters in the hardware configuration file. , and at the same time collect statistics on the traffic used by the access device.

During implementation, if it is determined based on the current working parameters that the terminal equipment is in good reception status and the received signal power is stable within a preset range of a certain value (the received signal power is above or below a certain value), then the received signal power can be determined based on the stable received signal. Power value, from the hardware configuration file, determine the corresponding target Bluetooth protocol, target transmit power level, and target transmit power. According to the current working parameters, it is determined that the working status between the access device and the terminal device has changed, and the corresponding target Bluetooth protocol, target transmission power level, and target transmission power are determined from the hardware configuration file according to the changed working status. For example: If the traffic suddenly increases, you can choose to switch to the Bluetooth protocol with larger traffic and the corresponding transmission level, transmission power and other parameters.

The second adjustment method is manual setting adjustment.

The overall idea of manual setting adjustment is: the user manually configures the Bluetooth working information of the terminal device through the Bluetooth connection setting APP pre-installed in the terminal device based on the actual situation and usage scenarios of traditional Bluetooth. After the configuration is completed, the Bluetooth pairing is opened, and based on judgment As a result, the transmission parameters and hardware status in the hardware configuration file module are adjusted, the hardware circuit part is configured, and the optimized parameters in the hardware configuration file are maintained. At the same time, the traffic used by the access device is counted. Once the set conditions and thresholds are exceeded, an alarm is initiated. mechanism to end the Bluetooth connection work or other programs, display information on the terminal interface, and wait for the user's next operation.

For the manual setting adjustment part, the user can select the Bluetooth working mode according to the actual situation. In one embodiment, the initial Bluetooth working mode is determined from at least one Bluetooth working mode; the designated Bluetooth protocol and the matching initial Bluetooth working mode are determined. Specify the transmission parameters; use the specified Bluetooth protocol as the initial Bluetooth protocol, and use the specified transmission parameters as the initial transmission parameters. At the beginning of the connection, the terminal device and the access device conduct Bluetooth communication according to the initial Bluetooth protocol and initial transmission parameters.

During implementation, when determining the initial Bluetooth working mode, the second selection operation input by the user can be obtained, and in response to the second selection operation, the initial Bluetooth working mode is determined from at least one Bluetooth working mode.

Bluetooth working modes include: single device connection mode and multi-device connection mode. These two modes are respectively set to use a large data traffic mode (such as WIFI sharing hotspot, etc.), and a medium data traffic mode (such as voice navigation, car Bluetooth devices, etc.). Listening to music, etc.), using low data traffic mode (such as listening to music with headphones, making and receiving calls, monitoring whether there are calls on the mobile phone, etc.), a total of 6 Bluetooth working modes.

For example: the user knows that there are two access devices to establish Bluetooth communication with the terminal device, one for listening to music, If one is used to transmit data, and the data traffic is not particularly large, you can choose multi-device connection - medium data traffic mode from the many Bluetooth working modes.

During implementation, the corresponding Bluetooth working parameters (Bluetooth protocol, transmission parameters, etc.) can be configured in advance for each Bluetooth working mode. According to the corresponding relationship, the initial Bluetooth protocol and initial transmission parameters corresponding to the multi-device connection-medium data traffic mode can be determined. .

After the access device is connected to the terminal device according to the initial Bluetooth protocol and initial transmission parameters, the working status of the access device and the terminal device can be determined based on the actual current working parameters of the access device to enable the optimized number of radio frequency channels in the hardware configuration file. Optimize the corresponding transmission protocol selection, power level, and transmission power configuration, maintain the optimized parameters in the hardware configuration file, and collect statistics on the traffic used by the access device.

In one embodiment, the working status of the access device and the terminal device is determined based on the current working parameters. If it is determined that the current Bluetooth protocol and transmission parameters are no longer suitable for the current working status and it is necessary to optimize the Bluetooth working parameters, from at least one In the Bluetooth working mode, select the target Bluetooth working mode; select the target Bluetooth protocol and target transmission parameters corresponding to the target Bluetooth working mode, and continue working with the target Bluetooth protocol and target transmission parameters.

During implementation, if it is determined that the current Bluetooth protocol and transmission parameters are no longer suitable for the current working status and it is necessary to optimize the Bluetooth working parameters, a change operation prompt can be output on the display module of the terminal device to remind the user to change the current Bluetooth working mode. , to modify Bluetooth working parameters. Obtain the first selection operation of the input; in response to the first selection operation, select the target Bluetooth working mode from at least one Bluetooth working mode, select the target Bluetooth protocol and target transmission parameters corresponding to the target Bluetooth working mode, and use the target Bluetooth protocol and Target launch parameters continue to work.

In fact, whether it is automatic setting adjustment or manual setting adjustment, the working status of the access device and terminal device will be monitored and the status will be updated in real time. When the paired device changes due to the receiving status, or the feedback request protocol changes and the traffic of the application used increases, , or when the hardware environment conditions of the two devices change, it will be enabled again to optimize the number of radio frequency channels, optimize the corresponding transmission protocol selection, power level, and transmission power configuration, and maintain the optimized parameters in the hardware configuration file, while counting access The traffic used by the device.

In an exemplary implementation, during the working process of the access device and the terminal device, the connection duration, traffic usage, and power consumption of the terminal device between the access device and the terminal device are counted, and the preset connection duration, Preset traffic upper limit and preset power consumption; if the preset conditions are met, disconnect the Bluetooth communication between the access device and the terminal device, and save the current Bluetooth protocol and current transmission parameters used by the access device and the terminal device; preset Suppose the conditions include at least one of the following conditions: the connection duration exceeds the preset connection duration; the traffic usage exceeds the preset traffic limit; the power consumption of the terminal device exceeds the preset power consumption; the power consumption of the terminal device exceeds the preset power consumption for a period of time Exceeded the preset time.

Among them, for the preset power consumption, different preset power consumption can be set according to different Bluetooth protocols. During implementation, one of the conditions can be met, that is, the connection is disconnected, or at least two or three of them can be met, or the connection can be disconnected only when all conditions are met.

In an exemplary embodiment, after disconnecting the Bluetooth communication between the access device and the terminal device and saving the current Bluetooth protocol and current transmission parameters used by the access device and the terminal device, the method further includes: obtaining an unlocking password; wherein , the unlocking password is used to reactivate the Bluetooth communication between the terminal device and the access device; and if the unlocking password is consistent with the preset unlocking password, the access device and the terminal device continue Bluetooth communication according to the current Bluetooth protocol and current transmission parameters. .

When implemented, the unlocking password can be input by the user after disconnecting the Bluetooth connection between the terminal device and the access device. If the unlocking password is verified, the Bluetooth communication between the terminal device and the access device can be continued.

In practical applications, whether it is automatic setting adjustment or manual setting adjustment, when the traffic used by the access device reaches the set traffic limit or working time limit, or the access device uses the Bluetooth connection function, resulting in the terminal device being at the maximum limit in the protocol for a long time. When power is generated, the system software starts the alarm mode, forces the access device to disconnect, and sets Bluetooth to be invisible, ends the Bluetooth pairing of the access device and the terminal device, and saves the relevant Bluetooth configuration at the last moment. If the access device still wants to pair with the Bluetooth of this terminal device, it needs to reset the Bluetooth of this terminal device, or enter a specially designed password in the system dialing interface to unlock and clear the relevant data.

In order to facilitate understanding of the technical solutions provided by the embodiments of the present disclosure, the automatic setting adjustment and manual setting adjustment provided by the embodiments of the present disclosure will be further described below with reference to FIGS. 4 to 5 .

As shown in Figure 4, an automatic setting adjustment method provided by an embodiment of the present disclosure mainly includes the following three steps.

Step 1: Open the Bluetooth connection setting interface in the interface settings of the terminal device, and set the Bluetooth MIMO mode selection, Bluetooth connection name, PIN code and other relevant upper-layer information. Based on the determination of the transmitting status and receiving status of the terminal device, The initial transmission level, protocol type and transmission power configuration predetermined in the hardware configuration file are enabled, and the Bluetooth connection function of the terminal device is turned on.

The second step is to wait for other devices to pair with the Bluetooth of the terminal device. If no other device is paired with the Bluetooth of the terminal device, close the Bluetooth connection setting option and display relevant information on the interface to remind the user that the Bluetooth connection has been closed. If The existing device is paired with the Bluetooth of the terminal device. Based on the request application type of the access device, the traffic estimation of the used application, and the determination of the receiving status, the hardware configuration file is enabled to optimize the number of radio frequency channels and optimize the corresponding transmission protocol. Select, power level, transmit power configuration, and maintain the optimized parameters in the hardware configuration file, while counting the traffic used by the access device.

The third step is to monitor the Bluetooth working status of the access device and the paired device, and update the working status in real time. When the paired device changes the receiving status, or the feedback request protocol changes and the traffic of the application used increases, or two mobile terminals If the hardware environment conditions change, re-enable the optimized number of radio frequency channels in the hardware configuration file, optimize the corresponding transmission protocol selection, power level, and transmission power configuration, and maintain the optimized parameters in the hardware configuration file, while counting the traffic used by the access device.

When the traffic used by the access device reaches the set traffic limit or working time limit, or the access device uses Bluetooth The connection function causes the terminal device to be in the maximum power generation state in the protocol for a long time. The system software starts the alarm mode, forces the access device and the terminal device to disconnect the Bluetooth connection, and sets Bluetooth to be invisible, ending the communication between the access device and the terminal device. Bluetooth pairing, save the last moment Bluetooth related configuration. If the access device still wants to pair with the Bluetooth of this terminal device, you need to reset the Bluetooth of this terminal device, or enter a specially designed password in the system dialing interface to unlock and clear the relevant data, and continue to the second step.

Then, the implementation of the manual setting adjustment method is described in conjunction with Figure 5. The implementation of this method is based on the user side. When the user configures the Bluetooth working status of the terminal device, it can be based on the Bluetooth working status and working status. , select the status of Bluetooth and establish it by yourself, which can complete good human-computer interaction.

The first step is to open the Bluetooth connection setting APP interface, select the Bluetooth MIMO mode, set the name of the Bluetooth connection, PIN code and other related upper-layer information, and set the connection time limit and traffic limit. In addition, it is different from the automatic setting adjustment. method, users need to choose the following modes according to the Bluetooth usage of the terminal device or the use of Bluetooth with the paired device: using a large data traffic mode (such as WIFI shared hotspot, etc.), using a medium data traffic mode (such as voice navigation, car Listening to music on Bluetooth devices, etc.), using low data traffic mode (such as listening to music with headphones, making and receiving calls, monitoring whether there are calls on the mobile phone, etc.), whether using multi-device connection sharing mode (such as multiple sets of headphones to listen to music together, one set of headphones to listen to music together, etc.) Device navigation, listening to music on another set of devices, etc.).

The second step is to wait for Bluetooth pairing between other devices and the terminal device. If no device is currently paired with the terminal device, turn off the Bluetooth setting option and report information to the interface to remind the user that the Bluetooth hotspot has been turned off. If there is already a device paired with the terminal device, For Bluetooth pairing of terminal devices, according to the manually set relevant conditions, the relevant situations in each mode are first matched and grouped with the optimized corresponding configurations in the hardware configuration file, and then the reception status of the access device and the status of the terminal device are determined. Enable the optimization of the corresponding transmission protocol selection, power level, and transmission power configuration in the hardware configuration file, maintain the optimization parameters in the hardware configuration file, and collect statistics on the traffic used by the access device.

The third step is to monitor the working status of the access device and the connected Bluetooth device, and update the status in real time. When the Bluetooth paired device changes in the receiving status, or the feedback request protocol type is modified and the traffic of the application used increases, the user needs to On this terminal device, re-establish the newly configured Bluetooth, and the device paired with it also needs to be re-paired with the Bluetooth of this terminal device; when the traffic used by the access device reaches the set traffic limit, the system software starts the alarm mode and forces access to the device Disconnect to end the Bluetooth pairing connection between the device and this terminal device, and save the last moment Bluetooth related configuration. If the accessed device still wants to perform Bluetooth pairing and connection work with the terminal device, it needs to enter the Bluetooth settings APP interface of the terminal device, unlock and clear the relevant data, and continue to the second step.

Among them, the manual setting adjustment method will cause changes in the user interface compared with related technologies, and this change will bring significant improvement in user experience.

First, the user opens the Bluetooth settings interface and can choose whether to enable Bluetooth MIMO mode. Then, enter the first-level menu and select Bluetooth mode. There are two options. The first option is Bluetooth portable device, and the second option is For Bluetooth terminal devices, the first option is Bluetooth headsets, cars, Bluetooth-enabled printers, etc., and the second option is Bluetooth mobile phones, tablets, laptops and other terminal devices; after entering the first option, switch to the second-level menu selection, and the user enters After this menu, you can determine the content of the second-level menu according to which option your terminal device is in the first-level menu. The second-level menu under the Bluetooth terminal device is divided into large data traffic modes (such as WIFI sharing hotspots, etc.) , use the medium data traffic mode (such as voice navigation, listening to music on car Bluetooth devices, etc.), use the small data traffic mode (such as listening to music with headphones, making and receiving calls, monitoring whether there are calls on the mobile phone, etc.); users can follow the = after Bluetooth pairing If the terminal device or other device uses Bluetooth, you can select the options in the second-level menu by yourself. Among the first-level menus, the second-level menu of the Bluetooth connection mode is not a relevant change of the present disclosure, so it will not be introduced here for the time being. The third-level menu pops up based on the results of the first-level menu and the second-level menu. The third-level menu mainly displays the statistics of the user's choices and adds a Bluetooth pairing button, so that the user can complete the tasks according to their own operations on the APP. The Bluetooth working status of the mobile terminal device is created, and the mobile terminal device selects the protocol and transmission power with the minimum power consumption according to the manually set relevant parameters, combined with the hardware indicators and capabilities, and turns on the Bluetooth function for other devices to connect and use.

At the same time, in order to reduce the tedious process of Bluetooth connection, you can add a whitelist. After adding the certified access device to the whitelist, the next time you connect to the access device, if the access device is in the whitelist, you can connect directly. This can reduce repeated data encryption and decryption processes and the identity verification process required for each connection, thereby reducing the application of the baseband part of the terminal device, reducing the resource utilization of the mobile terminal device, releasing some processing resources, and improving the mobile terminal The operating speed of the device.

In summary, the technical solution provided based on the present disclosure has great advantages for both users and terminal devices.

First of all, for users, when using terminal devices, it has the following advantages: 1. Monitor the Bluetooth usage of the device, so that the traffic and time used by the device paired with the terminal device can be controlled, and the Bluetooth usage can be dynamically adjusted; 2. Reduce the replacement speed of the terminal, because the temperature can always be maintained within a certain range, which reduces aging and increases the service life of the battery; 3. During Bluetooth connection, although the human body will be radiated if it is too close, it is not like before The hotspot mechanism will reduce the radiation to the human body and allow users to use it with confidence; and 4. When the user uses the terminal device, if the antenna is blocked or fails, the antenna of another channel can be activated immediately to ensure that the antenna is in use during use. There will be no disconnection or noise, intermittent sounds or other phenomena that affect the user experience due to antenna efficiency issues.

Secondly, for terminal equipment, it has the following advantages: The impact on the battery, because the terminal equipment adopts this mechanism, the state of rapid consumption of power is weakened, which will cause the battery heating to be within a controllable range, reducing The consumption speed of the battery also reduces the number of charges and discharges, increasing the service life of the battery; reducing the application of the baseband part of the terminal device, reducing the resource utilization of the terminal device, releasing some processing resources, and improving the operating speed of the terminal device; and Reduce the power consumption of related chips in terminal equipment and reduce the risk factor of the chip transmitting high power for a long time. This reduces the chance of chip damage and ensures the normal use of related functions of the terminal equipment.

Next, the Bluetooth power adjustment method provided by the embodiments of the present disclosure will be further described with reference to examples.

First, set the application scenario as follows: one mobile phone’s Bluetooth usage, the connecting and pairing device is another mobile phone, the purpose of pairing the other mobile phone with this mobile phone is to use Bluetooth direct connection mode for data transmission, and then stop the data After the transmission, the Bluetooth shared hotspot was used to download large-scale online games. Finally, the traffic reached the upper limit. At the same time, the two mobile phones were placed relatively close to each other and the signal quality was very good. For devices that apply this technology or implementation method, not all devices in the scenario will adopt this method and approach. It mainly depends on the functional status and connection status of the device in the Bluetooth application scenario, so that what is achieved is dynamic. Adjust the status to ensure the effect of user experience. In the above application scenarios, it is obvious that mobile phones that transmit data and provide Bluetooth shared hotspots are the main devices using this method and approach.

Secondly, an example analysis is conducted on the method of automatically adjusting Bluetooth configuration settings. Mobile phone A is the main device, and another mobile phone that needs to access the Internet is called mobile phone B. The user completes the Bluetooth configuration settings of mobile phone A and waits for mobile phone B to communicate with mobile phone A. Bluetooth pairing. After mobile phone B is paired successfully, data transmission begins. At this time, mobile phone A starts to optimize the Bluetooth performance of the terminal device. By obtaining the working parameters of mobile phone B, it is determined that the request rate of mobile phone B does not need to be very fast. At the same time, the traffic of the application used Relatively few. At the same time, the transmitting status of the two mobile phones meets the hardware indicators. The receiving status of both mobile phones is very good, and the received signal is maintained at about -25dBm. At this time, it is detected that the hotspot parameters of mobile phone A are in Bluetooth 4.0 protocol mode. The power level is class1 and the power is 11dBm. According to the corresponding optimization standards and indicator analysis and judgment conclusions, the mode needs to be lowered. At the same time, reducing the power will reduce the chip current inside mobile phone A, release some resources, and reduce the power consumption of mobile phone A. , enable the optimization of the corresponding transmission protocol selection, power level, and transmission power configuration in the hardware configuration file, change the Bluetooth parameters of mobile phone A to the Bluetooth protocol mode unchanged (still Bluetooth 4.0 protocol mode), the power level is class2, and the power is 4dBm. And keep the optimized parameters in the hardware configuration file, and at the same time, count the traffic used by the access device; at this time, after mobile phone B stops transmitting data, it starts to use the Bluetooth shared hotspot to download large-scale online games. At this time, the traffic of the applications used increases, which is similar to that of mobile phone A. The relative position remains the same as before. Mobile phone A detects a sudden increase in traffic conditions of mobile phone B, and the traffic of the application used increases. At this time, mobile phone A once again enables the optimization of the corresponding transmission protocol selection, power level, and transmission power configuration in the hardware configuration file. Change the Bluetooth parameters of mobile phone A to: the Bluetooth protocol mode is the Bluetooth BLE protocol mode, the power is at 0dBm, and keep the optimized parameters in the hardware configuration file. At the same time, it counts the traffic used by the access device; after a period of time, it is found that the traffic used by mobile phone B has reached the upper limit. , the system software of mobile phone A activates the alarm mode and hides Bluetooth, forcing mobile phone B to disconnect and making the Bluetooth device invisible. However, because the software of mobile phone B has not been downloaded, the user enters the hotspot unlock code on the keyboard of mobile phone A, and the system automatically switches the Bluetooth setting to To be visible, keep the previous Bluetooth BLE protocol mode, the power is at 0dBm, and the B mobile phone and A mobile phone are paired and connected via Bluetooth.

Finally, an example analysis is conducted on the software for manually setting Bluetooth configuration and the implementation method of enabling multi-device sharing mode. Similarly, devices that apply this technology or implementation method will not adopt this method for multiple devices in the scenario. It mainly depends on the functional status and connection status of the device in the Bluetooth application scenario, so as to achieve It is a dynamic adjustment state to ensure the effect of user experience. In the above scenario, it is obvious that mobile phones that transmit data and provide Bluetooth shared hotspots are the main devices using this method and approach.

The mobile phone that provides Bluetooth service is called mobile phone A, which is the main device. In addition, the two Bluetooth audio devices are device B and device C. The user opens the Bluetooth configuration APP of mobile phone A and starts setting up Bluetooth. Because device B needs to be connected For navigation audio, device C needs to play the audio of mobile phone A and start the multi-device simultaneous interpretation mode. The user judges that there will not be too much traffic, but needs to keep device B and device C connected at the same time. Select the Bluetooth MIMO mode by yourself - the network is using data traffic. mode, after the selection is completed, mobile phone A starts to create Bluetooth, and device B and device C are paired with the Bluetooth created by mobile phone A. At this time, mobile phone A configures the Bluetooth MIMO mode and enables the optimization of the corresponding transmission protocol selection and power level in the hardware configuration file. , transmit power configuration, set the Bluetooth 4.0 protocol mode, the power level is at class1, the power is at 7dBm, and keep the optimized parameters in the hardware configuration file, and at the same time count the traffic used by the access device; at this time, the user uses the B device to use the Bluetooth hotspot sharing function , at the same time, device C needs to be no longer in use, and device B starts to download software. At this time, the traffic of the application used increases, and the relative position with mobile phone A remains the same as before. Mobile phone A detects that the traffic of the application of device B rises quickly, and device C does not Connect to mobile phone A and start prompting the user to change the Bluetooth configuration on the interface. The user switches the Bluetooth configuration mode to the large network data traffic mode, clicks to reconfigure the hotspot option, the Bluetooth BLE protocol mode of mobile phone A, the power is at 0dBm, and turns off Bluetooth MIMO. mode, and maintain the optimized parameters in the hardware configuration file, and at the same time, count the traffic used by the access device; after a period of time, it is found that the traffic used by device B reaches the upper limit, and the system software of mobile phone A starts the alarm mode, forcing device B to disconnect, causing Bluetooth to automatically Change to invisible, and the Bluetooth Settings APP option is grayed out. However, since the download of the B device software has not been completed, the user activates the Bluetooth Settings APP option on the A phone, unlocks it, clears the relevant data, and manually sets the hotspot to visible, but the user needs Re-select the Bluetooth settings APP. After the selection is completed, mobile phone A will re-maintain the Bluetooth BLE protocol mode according to the hardware configuration file and the power is at 0dBm. Device B will re-pair and connect with mobile phone A via Bluetooth. The entire terminal device will be a hotspot. The workflow execution of the performance optimization module is as above.

Regardless of the two methods or approaches, the ultimate goal is to reduce the current of the Bluetooth module, thereby reducing the power consumption of the overall terminal device, achieving the purpose of saving power, and extending the service life of the terminal.
