Description

Technical Field

[0001] This application relates to the field of mobile terminals, and more particularly to a communication method, a communication circuit, and a mobile terminal. Background Technology

[0002] Most mobile terminals include a Bluetooth module and an antenna to enable communication between the mobile terminal and other devices in different scenarios. Currently, in some cases, the performance of the Bluetooth module is low, affecting the services it is currently performing. Summary of the Invention

[0003] This application provides a communication method, a communication circuit, and a mobile terminal for improving the performance of a Bluetooth module without significantly affecting the performance of other communication modules.

[0004] To achieve the above objectives, this application adopts the following technical solution: In a first aspect, a communication method is provided, applied to a mobile terminal including a communication circuit, a first antenna, and a second antenna. The communication circuit includes a first radio frequency integrated module connected to both the first and second antennas, and a second radio frequency integrated module connected to the first antenna. The first radio frequency integrated module corresponds to a Bluetooth module, and the second radio frequency integrated module corresponds to a cellular module. Furthermore, both the first and second integrated modules are connected to the processor of the mobile terminal.

[0005] Specifically, the communication method includes: a second radio frequency integrated module transmitting data through a first antenna (i.e., the cellular module occupies the first antenna), and a first radio frequency module transmitting data through a second antenna (i.e., the Bluetooth module occupies the second antenna). If the current performance of the Bluetooth module is lower than a preset performance level, and the priority of the Bluetooth module's service is higher than that of the cellular module's service, it indicates that the Bluetooth module can improve its performance by temporarily preempting the cellular module's antenna. Therefore, the second radio frequency module can be controlled to stop transmitting data through the first antenna, and the first radio frequency integrated module can be controlled to switch from transmitting data through the second antenna to transmitting data through the first antenna, i.e., the cellular module can be controlled to stop occupying the first antenna, and the Bluetooth module's operating antenna can be switched from the second antenna to the first antenna. Furthermore, if the first received signal strength is greater than the second received signal strength, it indicates that the Bluetooth module performs better when transmitting data through the first antenna. Therefore, the first radio frequency integrated module can be kept transmitting data through the first antenna, i.e., the Bluetooth module can be kept occupying the first antenna. In other words, in the solution of this application, by switching the antenna corresponding to the Bluetooth module, the performance of the Bluetooth module is optimized, while minimizing impact on the operation of the cellular module.

[0006] It should be noted that the first received signal strength is the received signal strength of the Bluetooth module when the first radio frequency integrated module transmits data through the first antenna; the second received signal strength is the received signal strength of the Bluetooth module when the first radio frequency integrated module transmits data through the second antenna.

[0007] In one possible implementation of the first aspect, before maintaining control of the first radio frequency integrated module to transmit data through the first antenna if the first received signal strength is greater than the second received signal strength, the communication method provided by this application further includes: if the first radio frequency integrated module transmits data through the second antenna (i.e., the first radio frequency module occupies the second antenna), the second radio frequency integrated module does not transmit data through the first antenna (i.e., the second radio frequency module does not occupy the first antenna), and the current performance of the Bluetooth module is lower than the preset performance, the first radio frequency integrated module can be directly controlled to switch from transmitting data through the second antenna to transmitting data through the first antenna. That is, the Bluetooth module can directly preempt the antenna of the cellular module to improve its own performance without affecting the performance of the cellular module.

[0008] In another possible implementation of the first aspect, the Bluetooth-related antennas in the mobile terminal are distributed at the top and bottom of the mobile terminal. Based on this, the priority of the Bluetooth module's services is higher than that of the cellular module's services, which may include: the priority of the Bluetooth module's services is higher than that of the cellular module's services, and the current posture of the mobile terminal is a preset posture. The preset posture of the mobile terminal may include: the top or bottom of the mobile terminal facing the target Bluetooth device. The target Bluetooth device is the Bluetooth device that collaborates with the mobile terminal to perform tasks after establishing a Bluetooth connection.

[0009] In another possible implementation of the first aspect, the communication method provided by this application may further include: determining whether the second radio frequency integrated module transmits data through the first antenna when the Bluetooth module has been started and the Bluetooth module and the cellular module support time-division multiplexing of the same antenna.

[0010] In this solution, the mobile terminal will only execute the communication method provided in this application if the Bluetooth module is enabled and the Bluetooth module and cellular module support time-division multiplexing of the same antenna. Specifically, the mobile terminal determines whether the second RF integrated module occupies the first antenna to determine the corresponding branch to execute. If the Bluetooth module is not enabled, and / or if the Bluetooth module and cellular module do not support time-division multiplexing of the same antenna, the mobile terminal will not execute the communication method provided in this application, thus saving system resources of the mobile terminal.

[0011] In another possible implementation of the first aspect, the communication method provided by this application may further include: determining whether the Bluetooth module and the cellular module support time-division multiplexing of the same antenna under any of the following conditions: the priority of the Bluetooth module's service is lower than the priority of the cellular module's service, indicating that the Bluetooth module cannot preempt the cellular module's antenna; the current posture of the mobile terminal is not a preset posture, and the first received signal strength is less than the second received signal strength, indicating that the Bluetooth module's effect of preempting the cellular module's antenna is not good; the current performance of the Bluetooth module is higher than the preset performance; the Bluetooth module is working, and during the operation of the Bluetooth module, the mobile terminal can periodically execute the communication method provided by this application.

[0012] In another possible implementation of the first aspect, the communication circuit may further include a first switch module, a second switch module, a first radio frequency front-end module, a second radio frequency front-end module, and a third radio frequency front-end module. Furthermore, the second antenna may include a first sub-antenna and a second sub-antenna. Simultaneously, the first radio frequency integrated module transmits data through either the first sub-antenna or the second sub-antenna.

[0013] Based on this, the first end of the first switch module is connected to the first transmitting end of the first radio frequency integrated module, the second end of the first switch module is connected to the first receiving end of the first radio frequency integrated module, the third end of the first switch module is connected to the first end of the second switch module, the fourth end of the first switch module, the second transmitting end of the first radio frequency integrated module, and the second receiving end of the first radio frequency integrated module are connected to the first sub-antenna through the first radio frequency front-end module, and the third transmitting end, the third receiving end of the first radio frequency integrated module, and the fourth transmitting end of the first radio frequency integrated module are connected to the second sub-antenna through the second radio frequency front-end module.

[0014] The second terminal of the second switch module is connected to the first antenna, and the third terminal of the second switch module is connected to the first receiving terminal of the second radio frequency integrated module and the first transmitting terminal of the second radio frequency integrated module through the third radio frequency front-end module.

[0015] In another possible implementation of the first aspect, controlling the second radio frequency integrated module to stop transmitting data through the first antenna includes: disabling the first receiving end and the first transmitting end of the second radio frequency integrated module, turning off the third end of the second switching module and the second end of the second switching module, thereby shutting off the communication link between the second radio frequency integrated module and the first antenna.

[0016] The first radio frequency integrated module also corresponds to a wireless fidelity module. Therefore, the second receiver, second transmitter, third receiver, and fourth receiver of the first radio frequency integrated module include Bluetooth mode and wireless fidelity mode. Based on this, controlling the first radio frequency integrated module to switch from data transmission via the second antenna to data transmission via the first antenna can include the following two cases: In the first scenario, the second and third receivers of the first RF integrated module are disabled. Alternatively, the second and third receivers of the first RF integrated module are configured to Wi-Fi mode, i.e., the Bluetooth communication link between the second receiver and the first sub-antenna of the first RF integrated module is turned off, and the Bluetooth communication link between the third receiver and the second sub-antenna of the first RF integrated module is also turned off. This controls the first RF integrated module to stop receiving Bluetooth data through either the first or second sub-antenna. Simultaneously, the first receiver of the first RF integrated module is enabled, the second and third terminals of the first switch module are connected, and the first and second terminals of the second switch module are connected, i.e., the Bluetooth communication link between the first receiver of the first RF integrated module and the first antenna is connected. This controls the first RF integrated module to receive Bluetooth data through the first antenna.

[0017] In the second scenario, the fourth transmitter of the first RF integrated module, as well as the second and third transmitters of the first RF integrated module, are disabled. Alternatively, the second and third transmitters of the first RF integrated module are configured to Wi-Fi mode, and the first and fourth terminals of the first switch module are turned off. This disconnects the Bluetooth communication link between the second transmitter of the first RF integrated module and the first sub-antenna, thus controlling the first RF integrated module to stop transmitting Bluetooth data through the first sub-antenna. Similarly, disconnecting the Bluetooth communication link between the third transmitter of the first RF integrated module and the first sub-antenna also stops the first RF integrated module from transmitting Bluetooth data through the first sub-antenna. Simultaneously, the first transmitter of the first RF integrated module is enabled, and the first and third terminals of the first switch module are connected. The first and second terminals of the second switch module are also connected, thus establishing the Bluetooth communication link between the first transmitter of the first RF integrated module and the first antenna. This allows the first RF integrated module to transmit Bluetooth data through the first antenna.

[0018] In another possible implementation of the first aspect, the first switch module includes a first switch and a second switch. The first end of the first switch is connected to the first transmitting end of the first radio frequency integrated module, the second end of the first switch is connected to the first end of the second switch, and the third end of the first switch is connected to the first sub-antenna through the first radio frequency front-end module; the second end of the second switch is connected to the first receiving end of the first radio frequency integrated module, and the third end of the second switch is connected to the first end of the second switch module.

[0019] Based on this, connecting the first terminal and the third terminal of the first switch module includes: connecting the first terminal and the second terminal of the first switch, and connecting the first terminal of the second switch and the third terminal of the second switch. Connecting the second terminal and the third terminal of the first switch module includes: connecting the second terminal of the second switch and the third terminal of the second switch. Disconnecting the first terminal and the fourth terminal of the first switch module includes: disconnecting the first terminal and the third terminal of the first switch.

[0020] In another possible implementation of the first aspect, the second switch module includes a third switch and a fourth switch. The first end of the third switch is connected to the third end of the first switch module, and the second end of the third switch is connected to the first end of the fourth switch; the second end of the fourth switch is connected to the first antenna, and the third end of the fourth switch is connected to the first receiving end of the second radio frequency integrated module and the first transmitting end of the second radio frequency integrated module through the third radio frequency front-end module.

[0021] Based on this, turning off the third terminal of the second switch module and the second terminal of the second switch module includes: turning off the second terminal of the fourth switch and the third terminal of the fourth switch. Turning on the first terminal of the second switch module and the second terminal of the second switch module includes: turning on the first terminal of the third switch and the second terminal of the third switch, and turning on the first terminal of the fourth switch and the second terminal of the fourth switch.

[0022] In another possible implementation of the first aspect, the communication circuit further includes a fifth switch, with a first terminal connected to a first terminal of the second switch module and a second terminal connected to a third terminal of the first switch module. Furthermore, controlling the second radio frequency integrated module to transmit data through the first antenna further includes turning on the first and second terminals of the fifth switch.

[0023] Secondly, this application provides a communication circuit applied to a mobile terminal including a first antenna and a second antenna. The communication circuit includes a first radio frequency (RF) integrated module and a second RF integrated module. The first RF integrated module is connected to the first antenna and the second antenna, and the second RF integrated module is connected to the first antenna. Both the first RF integrated module and the second RF integrated module are connected to the processor of the mobile terminal, and the first RF integrated module corresponds to a Bluetooth module, and the second RF integrated module corresponds to a cellular module. The processor is used to execute the communication method described in the first aspect and any one of the above.

[0024] Thirdly, this application provides a mobile terminal, including: a processor, a memory, a first antenna, a second antenna, and the communication circuit described in the second aspect. The processor is connected to the memory and various radio frequency integrated modules in the communication circuit. The memory stores computer program code, which includes instructions.

[0025] Fourthly, a computer-readable storage medium is provided, which stores instructions that, when executed on a mobile terminal, enable the mobile terminal to perform the communication method described in the first aspect and any one thereof.

[0026] Fifthly, a computer program product containing instructions is provided, which, when run on a mobile terminal, enables the mobile terminal to execute the communication method described in the first aspect and any one thereof.

[0031] The terms "exemplary" or "for example" used in the embodiments of this application are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0032] The terms "coupling" and "connection" used in the embodiments of this application should be interpreted broadly. For example, they can refer to a physical direct connection or an indirect connection achieved through electronic devices, such as a connection achieved through resistors, inductors, capacitors or other electronic devices.

[0033] Currently, most mobile terminals include multiple communication modules and multiple antennas to enable communication with other devices in different scenarios. For example, communication modules may include cellular modules for long-range communication, and wireless fidelity (WiFi) modules and Bluetooth (BT) modules for short-range communication. It should be understood that the number of communication modules and the number of antennas are not exactly the same. For example, multiple communication modules can transmit data using a single antenna at different times.

[0034] One of the communication modules transmits data via an antenna, including: the communication module receives data via the antenna, or the communication module transmits data via the antenna.

[0035] The mobile terminal discussed in this article can be mobile or fixed, and can be deployed on land (e.g., indoors or outdoors, handheld or vehicle-mounted), on water (e.g., model boat), or in the air (e.g., drone). This mobile terminal can be referred to as user equipment (UE), access terminal, terminal unit, subscriber unit, terminal station, mobile station (MS), mobile station, terminal agent, or terminal device, etc. For example, the mobile terminal can be a mobile phone, tablet, laptop, smart bracelet, smartwatch, headphones, smart speaker, virtual reality (VR) device, augmented reality (AR) device, terminal in industrial control, terminal in self-driving, terminal in remote medical care, terminal in smart grid, terminal in transportation safety, terminal in smart city, terminal in smart home, etc. When the mobile terminal is a mobile phone, it can be a foldable screen phone or a non-foldable screen phone. The embodiments of this application do not limit the specific type and structure of the mobile terminal.

[0036] The following text uses a mobile phone as an example to illustrate the concept of a mobile terminal. Figures 1 to 2 This section introduces communication scenarios for mobile terminals. Figure 1 A schematic diagram of the structure of a communication system provided in an embodiment of this application is shown.

[0037] like Figure 1 As shown, mobile phone A can connect to other devices (such as tablet 110, laptop 120, and mobile phone B) via Bluetooth (or WiFi) to establish a Magic Ring, enabling collaborative communication. Mobile phone A can also make calls to mobile phone C via cellular network and connect to Bluetooth headset 130 via Bluetooth. This allows the user to talk to the user of mobile phone C without holding mobile phone A, simply by wearing Bluetooth headset 130. Mobile phone A can also connect to smartwatch 140 via Bluetooth, enabling data exchange between mobile phone A and smartwatch 140.

[0038] It should be noted that, Figure 1The devices shown can be devices within the same communication scenario. Alternatively, the scenario could be that mobile phone A establishes a trust loop with other devices, mobile phone A connects to mobile phone C and Bluetooth headset 130, or mobile phone A connects to smartwatch 140. This article does not impose any restrictions. Of course, mobile phone A can also communicate with corresponding devices through other communication modules to achieve communication in the corresponding scenario, which will not be listed one by one in this article.

[0039] Figure 1 In the corresponding scenario, the Bluetooth module, Wi-Fi module, or cellular module of the mobile phone A shown in the figure also needs to be combined with the corresponding antenna in the mobile phone A to communicate with the corresponding device. The antennas corresponding to the Bluetooth module, Wi-Fi module, and cellular module can be the same or different.

[0040] Antennas have a certain directionality. Therefore, when a user is using a mobile phone, the relative position (or orientation) of the phone and the user's body will differ, resulting in different main radiation directions (or simply radiation directions) of the antenna in the phone. The following text uses a Bluetooth module as an example, combined with... Figure 2 introduce.

[0041] Figure 2 The illustration shows a usage scenario in a mobile phone according to an embodiment of this application.

[0042] Taking a user holding a mobile phone and wearing Bluetooth headphones as an example, where the Bluetooth headphones establish a Bluetooth connection with the mobile phone. Figure 2 As shown, in a standing scenario, the radiation direction of the antenna corresponding to the Bluetooth module is direction 11. At this time, the Bluetooth headset 130 deviates from direction 11. (As...) Figure 2 As shown, in the pocket scenario, the user is standing upright and the phone is inserted vertically into the pocket. The radiation direction of the antenna corresponding to the Bluetooth module is direction 21. At this time, the Bluetooth headset 130 is located in direction 21. Figure 2 As shown, in a seated scenario, the phone is placed flat on a table, and the radiation direction of the antenna corresponding to the Bluetooth module is direction 31. At this time, the Bluetooth headset 130 deviates from direction 31. For example... Figure 2 As shown, in a walking scenario, when the user is walking and holding the phone backwards (i.e., the top of the phone is facing backwards), the radiation direction of the antenna corresponding to the Bluetooth module is direction 41. At this time, the Bluetooth headset 130 deviates from direction 41.

[0043] The communication link operates at its optimal performance when the peer device is aligned with the antenna's radiation direction. However, if the peer device is aligned with the antenna's radiation direction but there are obstacles between them, or if the peer device deviates from the antenna's radiation direction, the performance of the communication link will decrease, thus reducing the performance of the corresponding communication module. The peer device refers to the device that establishes communication with the mobile phone.

[0044] For example, a parameter used to measure the performance of a communication link is the received signal strength indicator (RSSI), and... Figure 2 Taking the antenna radiation direction shown in any usage scenario as an example, when the Bluetooth headset is located at the top of the phone (i.e., the Bluetooth headset is in the radiation direction of the antenna corresponding to the Bluetooth module), the performance of the Bluetooth module is -42dB; when the Bluetooth headset is located at the bottom of the phone (i.e., the Bluetooth headset is away from the radiation direction of the antenna corresponding to the Bluetooth module), the performance of the Bluetooth module is -45.8dB.

[0045] Currently, users have increasingly higher requirements for the communication performance of various communication modules. Taking the Bluetooth module as an example, Table 1 shows the Bluetooth performance requirements in different scenarios.

[0046] Table 1

[0047] As shown in Table 1, the requirements for Bluetooth audio transmission performance are becoming increasingly stringent. Mobile phones must have better Bluetooth performance in order to fully realize the potential of Bluetooth headsets in scenarios such as calls, recording, and music playback.

[0048] The Bluetooth module in the mobile terminal can correspond to multiple antennas. In order to improve the performance of the Bluetooth module during the Bluetooth module's activation, in this embodiment of the application, the mobile terminal can switch antennas for the Bluetooth module based on the actual situation so that the performance of the communication link corresponding to the Bluetooth module is optimal, thereby making the Bluetooth module perform optimally.

[0049] Specifically, this application provides a communication method, a communication circuit, and a mobile terminal. The Bluetooth module in the mobile terminal can correspond to three antennas, such as antenna 1, antenna 2, and antenna 3. Antenna 1 and antenna 2 are the default antennas of the Bluetooth module; antenna 3 is a time-division multiplexed antenna for the Bluetooth module and the cellular module, and is the default antenna for the cellular module. If the current performance of the Bluetooth module is detected to be lower than a preset performance, and if the cellular module is not using antenna 3, and the performance of the Bluetooth module using antenna 3 to transmit data is higher than the performance of the Bluetooth module using antenna 1 (or antenna 2), then the mobile terminal controls the Bluetooth module to switch from transmitting data through antenna 1 (or antenna 2) to transmitting data through antenna 3. If the cellular module is using antenna 3, but the priority of the Bluetooth module's current service is higher than the priority of the cellular module's current service, and the performance of the Bluetooth module using antenna 3 to transmit data is higher than the performance of the Bluetooth module using antenna 1 (or antenna 2), then the mobile terminal controls the Bluetooth module to switch from transmitting data through antenna 1 (or antenna 2) to transmitting data through antenna 3. In other words, while the Bluetooth module is working, the mobile terminal can switch the antenna for the Bluetooth module under certain conditions to optimize the performance of the Bluetooth module, while minimizing the impact on the cellular module's operation.

[0062] Figure 4 This illustration shows a schematic diagram of the location of the antenna corresponding to the Bluetooth module in a mobile phone, as provided in an embodiment of this application.

[0063] In one example, such as Figure 4 As shown, the Bluetooth module 401 in the mobile phone corresponds to three antennas, which can be referred to as antenna 1, antenna 2, and antenna 3. Antenna 1 is located at the top of the phone, antenna 2 is located on the left side of the phone near the top, and antenna 3 is located at the bottom of the phone. Antenna 1 and antenna 2 are time-division multiplexed antennas for the Bluetooth module and the Wi-Fi module, and are the default antennas for the Bluetooth module; antenna 3 is time-division multiplexed antennas for the Bluetooth module and the cellular module, and is the default antenna for the cellular module.

[0066] In one example, the phone's mid-frame can be used as an antenna. This provides better radiation efficiency through a larger physical size without taking up internal space, while cleverly solving the problem of signal obstruction when the user holds the phone by utilizing the mid-frame structure distributed on all four sides. Based on this, segment 1 of the mid-frame can serve as antenna 1, segment 2 as antenna 2, and segment 3 as antenna 3. Segment 1 is located at the top of the mid-frame, segment 2 can be located on the right side of the mid-frame near the top, and segment 3 can be located at the bottom of the mid-frame.

[0067] It is understood that the structure illustrated in this embodiment does not constitute a specific limitation on the mobile terminal 300. In other embodiments, the mobile terminal 300 may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0068] The following text combines Figures 5 to 9 This application describes the communication method and communication circuit provided in the embodiments. Figure 5 A flowchart illustrating a communication method provided in an embodiment of this application is shown. Figure 5 As shown, the communication method may include: S501. After the Bluetooth module is started, the mobile terminal determines whether the Bluetooth module and the cellular module support time-division multiplexing of the same antenna.

[0069] The Bluetooth module can have two preset flag bits: flag 1 and flag 2. Flag bit 1 indicates whether the Bluetooth module is in working condition, and flag bit 2 indicates whether the Bluetooth module and the cellular module time-division multiplex the same antenna. If the Bluetooth module and the cellular module time-division multiplex the same antenna, meaning that the Bluetooth module or the cellular module transmits data through the antenna at different times, it can be understood that the mobile terminal supports independent Bluetooth functionality; otherwise, the mobile terminal does not support independent Bluetooth functionality.

[0070] For example, flag 1 can be identified by different values ​​to indicate whether the Bluetooth module is in a working state. When flag 1 is a value of 1 (e.g., 1), it indicates that the Bluetooth module is in a working state; when flag 1 is a value of 2 (e.g., 0), it indicates that the Bluetooth module is in a non-working state. In S501, after the Bluetooth module is started, the Bluetooth module transmits data through antenna 1 or antenna 2.

[0071] Flag 2 can be used with different values ​​to indicate whether the Bluetooth module and the cellular module time-division multiplex the same antenna. When flag 2 is 1, it indicates that the Bluetooth module and the cellular module time-division multiplex the same antenna; when flag 2 is 2, it indicates that the Bluetooth module and the cellular module do not time-division multiplex the same antenna.

[0072] Therefore, the mobile terminal can determine whether the Bluetooth module is powered on by reading flag bit 1 in the Bluetooth module, and after determining that the Bluetooth module is powered on, it can read flag bit 2 in the Bluetooth module to determine whether the Bluetooth module and the cellular module are time-division multiplexing the same antenna. If the Bluetooth module and the cellular module are time-division multiplexing the same antenna, the mobile terminal can execute the following S502; if the Bluetooth module and the cellular module are not time-division multiplexing the same antenna, the mobile terminal can terminate the communication method provided in this application embodiment and execute the original related process, which will not be described in detail here.

[0073] S502, The mobile terminal obtains the operating parameters of the Bluetooth module at the current moment.

[0074] The operating parameters of a Bluetooth module may include, but are not limited to, data rate, bandwidth, and received signal strength. Based on this, operating parameter 1 may include, but is not limited to, data rate 1, bandwidth 1, and received signal strength 1. The received signal strength, which can be referred to as the second received signal strength, is the received signal strength of the Bluetooth module when transmitting data through antenna 1 or antenna 2.

[0075] In one example, S501 and S502 can be executed simultaneously or sequentially; this article does not impose any restrictions on this.

[0076] In one example, the mobile terminal can skip S501 and directly execute S502.

[0077] S503: The mobile terminal determines whether the current performance of the Bluetooth module is lower than the preset performance.

[0078] In one example, the performance of a Bluetooth module can be measured based on parameters such as signal reception strength and throughput to determine if the module is experiencing lag. The throughput at a given moment can be determined based on parameters such as the module's current data rate and bandwidth. The Bluetooth module's performance can be assessed by checking whether its current throughput meets the requirements of the application using the module and whether its current signal reception strength is below a threshold of 1 to determine if its performance is below a preset performance level.

[0079] For example, if both the rate 1 and the bandwidth 1 are lower than the requirements of the application currently using the Bluetooth module, and the received signal strength 1 is less than the threshold 1, the mobile terminal can determine that the performance of the Bluetooth module at the current moment is lower than the preset performance, and the mobile terminal can execute the following S504; conversely, the mobile terminal can determine that the performance of the Bluetooth module at the current moment is higher than the preset performance, and the mobile terminal can execute the above S501.

[0080] S504: The mobile terminal determines whether the cellular module is currently transmitting data through antenna 3.

[0081] The mobile terminal can determine the conduction status of the cellular communication link 4 by reading the path flag bit of the cellular communication link 4 between the antenna 3 and the cellular module, and thus determine whether the cellular module is currently transmitting data through the antenna 3. The path flag bit can be represented by the value 1 or the value 2. When the path flag bit is the value 1, it indicates that the cellular module is transmitting data through the antenna 3, and the mobile terminal can execute the following S505; when the path flag bit is the value 2, it indicates that the cellular module is not transmitting data through the antenna 3, and the mobile terminal can execute the following S506. The cellular communication link 4 involved in this step will be discussed in conjunction with the following text. Figure 6 The introduction will not be detailed here.

[0082] S505: The mobile terminal determines whether the priority of the Bluetooth module's service is greater than the priority of the cellular module's service at the current moment.

[0083] The mobile terminal has a pre-defined service priority table that lists the priorities of various services that the Bluetooth module can execute, as well as the priorities of various services that the cellular module can execute. Therefore, the mobile terminal can determine whether the priority of the Bluetooth module's service is higher than the priority of the cellular module's service at any given moment, based on the services currently being executed by the Bluetooth module, the services currently being executed by the cellular module, and the service priority table.

[0084] Antenna 3 is the default antenna for the cellular module, which is the highest priority communication module in the mobile phone. To ensure the communication performance of the cellular module, antenna 3 is usually positioned optimally within the phone. Based on this, if the priority of the Bluetooth module's service is currently higher than that of the cellular module's service, then the Bluetooth module can preferentially transmit data through antenna 3. Therefore, the mobile terminal can execute S506 as described below. If the priority of the Bluetooth module's service is currently lower than that of the cellular module's service, then the Bluetooth module cannot temporarily transmit data through antenna 3, otherwise it would affect the performance of the cellular module, thus affecting the cellular module's ability to execute higher-priority services. Therefore, the mobile terminal can execute S501 as described above.

[0085] S506: The mobile terminal determines whether the current posture belongs to the preset posture.

[0086] The preset posture may include the top (or bottom) of the mobile terminal facing the target Bluetooth device.

[0087] Mobile terminals can determine whether the current posture belongs to the preset posture based on the following two methods: Method 1: The mobile terminal pre-stores target poses for different scenarios. Based on this, the mobile terminal can obtain its pose using data from its internal sensors (such as at least one accelerometer, magnetometer, antenna sensor, gyroscope, etc.). If it detects that the mobile terminal's current pose belongs to the target pose in the current scenario, it can determine that the mobile terminal's current pose belongs to the preset pose. For example, using... Figure 2 Taking the pocket scenario as an example, when the phone is upright, the top of the phone faces the Bluetooth headset. Therefore, in the pocket scenario, when the mobile terminal detects that it is currently in an upright position, it can determine that the current posture belongs to the preset posture. The specific process by which the mobile terminal detects its posture based on its internal sensors can be found in related technical descriptions, and will not be elaborated upon here.

[0088] Method 2: The mobile terminal can determine whether its current posture belongs to a preset posture based on the signal quality of the Bluetooth module. For example, when the signal quality of the Bluetooth module is within a preset range, it can be determined that the current posture of the mobile terminal belongs to the preset posture; otherwise, it can be determined that the current posture of the mobile terminal does not belong to the preset posture.

[0089] If the current posture of the mobile terminal belongs to the preset posture, the mobile terminal can execute the following S507; if the current posture of the mobile terminal does not belong to the preset posture, the mobile terminal can execute the above S501.

[0090] In some examples, the mobile terminal may not execute S506. That is, in S505, if the mobile terminal determines that the priority of the Bluetooth module's service is greater than the priority of the cellular module's service at the current moment, then the following S507 is executed.

[0091] S507, The mobile terminal controls the cellular module to stop transmitting data through antenna 3, controls the Bluetooth module to switch from transmitting data through antenna 1 (or antenna 2) to transmitting data through antenna 3, and detects the received signal strength 2 of the Bluetooth module when the Bluetooth module transmits data through antenna 3.

[0092] The mobile terminal has a pre-set received signal strength detection algorithm. When the mobile terminal controls the Bluetooth module to transmit data through antenna 3, the received signal strength detection algorithm can be activated to obtain the received signal strength 2 (which can be called the first received signal strength).

[0093] The following text combines Figure 6 This paper describes the principle by which a mobile terminal controls the cellular module to stop transmitting data through antenna 3 and switches the Bluetooth module from transmitting data through antenna 1 (or antenna 2) to transmitting data through antenna 3. Figure 6 This illustration shows one of the structural schematic diagrams of a communication circuit provided in an embodiment of this application.

[0094] In one example, such as Figure 6 As shown, the communication circuit includes an RF integrated module 1 (which can be referred to as the first RF integrated module), an RF front-end module 1, an RF front-end module 2, a switch module 1 (which can be referred to as the first switch module), and a switch module 2 (which can be referred to as the second switch module). At any given time, the Bluetooth module transmits data through the RF integrated module 1, the RF front-end module 1 (or the RF front-end module 2), and the corresponding antenna; alternatively, the Wi-Fi module transmits data through the RF integrated module 1, the RF front-end module 1 (or the RF front-end module 2), and the corresponding antenna. The RF front-end module 1 and the RF front-end module 2 integrate an RF receiving path and an RF transmitting path. When data needs to be transmitted, the mobile terminal can control the corresponding RF front-end module to select the RF transmitting path; when data needs to be received, the mobile terminal can control the corresponding RF front-end module to select the RF transmitting path.

[0095] Specifically, the transmitter 1 (TX11) and receiver 1 (RX11) of the RF integrated module 1 are connected to the antenna 1 through the RF front-end module 1. The transmitter 2 (TX21) of the RF integrated module 1 is connected to port A1 of the switch module 1, and port A4 of the switch module 1 is connected to the antenna 1 through the RF front-end module 1. The receiver 2 (RX21) of the RF integrated module 1 is connected to port A2 of the switch module 1, port A3 of the switch module 1 is connected to port B1 of the switch module 2, and port B2 of the switch module 2 is connected to the antenna 3. The transmitter 3 (TX31), receiver 3 (RX31), and transmitter 4 (TX41) of the RF integrated module 1 are connected to the antenna 2 through the RF front-end module 2.

[0096] In some examples, the transmitting end 2 of RF integrated module 1 can be referred to as the first transmitting end of RF integrated module 1, and the receiving end 2 of RF integrated module 1 can be referred to as the first receiving end of RF integrated module 1. Port A1 of switch module 1 can be referred to as the first terminal of switch module 1, port A2 of switch module 1 can be referred to as the second terminal of switch module 1, port A3 of switch module 1 can be referred to as the third terminal of switch module 1, and port A4 of switch module 1 can be referred to as the fourth terminal of switch module 1. Port B1 of switch module 2 can be referred to as the first terminal of switch module 2, and port B2 of switch module 2 can be referred to as the second terminal of switch module 2. RF front-end module 1 can be referred to as the first RF front-end module, and RF front-end module 2 can be referred to as the second RF front-end module.

[0097] The following section, in conjunction with Table 2, describes the purpose of each port in the RF integrated module 1.

[0100] It should be noted that the receiver 2 and transmitter 2 of the RF integrated module 1 can meet the communication requirements of the Bluetooth module; therefore, the RF front-end module may not be required in the Bluetooth communication link 3. Figure 6 The receiver 2 and transmitter 2 of the RF integrated module 1 shown do not use an RF front-end module. Of course, in some examples, an RF front-end module can also be added to the Bluetooth communication link 3, that is, an RF front-end module can be added to the receiver 2 and transmitter 2 of the RF integrated module 1. This is not a limitation in this paper.

[0101] Then, continue as follows Figure 6 As shown, the communication circuit may further include an RF integrated module 2 (which can be called the second RF integrated module) and an RF front-end module 3 (which can be called the third RF front-end module). The RF integrated module 2 is the RF integrated module of the cellular module, and the RF front-end module 3 is the RF front-end module for some ports of the cellular module. The RF front-end module 3 integrates an RF receiving path and an RF transmitting path. When data needs to be transmitted, the mobile terminal can control the RF front-end module 3 to select the RF transmitting path; when data needs to be received, the mobile terminal can control the RF front-end module 3 to select the RF transmitting path.

[0102] Specifically, the transmitter 5 (TX5) of the RF integrated module 2 is connected to port B3 of the switch module 2 through the RF front-end module 3, and the receiver 5 (RX5) of the RF integrated module 2 is connected to port B3 of the switch module 3 through the RF front-end module 3. Port B3 of the switch module 2 can be referred to as the third terminal of the switch module 2.

[0104] Prior to S507, after the Bluetooth module was powered on, the mobile terminal could establish either Bluetooth communication link 1 or Bluetooth communication link 2 for data transmission. At this time, if the cellular module needed to perform a task, the mobile terminal could establish the cellular module's data transmission communication link. If the cellular module did not need to perform a task, the mobile terminal could disconnect the cellular module's communication link. The cellular module's data transmission communication links included, but were not limited to, cellular communication link 4.

[0108] The mobile terminal enables the Bluetooth transmission link 12, including: enabling the transmitter 2 of the RF integrated module 1, controlling the port A1 of the switch module 1 to be connected to the port A4 of the switch module 1, and controlling the RF front-end module 1 to select the RF transmission path, so that the transmitter 2 of the RF integrated module 1 is connected to the antenna 1, that is, the Bluetooth transmission link 12 is connected, so that the Bluetooth module can transmit data through the Bluetooth transmission link 1.

[0109] Specifically, the mobile terminal connects to Bluetooth communication link 2, including: the mobile terminal connects to Bluetooth receiving link 21, connects to Bluetooth transmitting link 21, or connects to Bluetooth transmitting link 22.

[0110] The process of the mobile terminal activating the Bluetooth receiving link 21 includes: the mobile terminal configuring the receiver 3 of the RF integrated module 1 to Bluetooth mode and controlling the RF front-end module 2 to select the RF receiving path, so that the receiver 3 of the RF integrated module 1 is connected to the antenna 2, that is, activating the Bluetooth receiving link 21, so that the Bluetooth module can receive data through the Bluetooth receiving link 2.

[0111] The mobile terminal connects to the transmission link 21, including: the mobile terminal configures the transmitter 3 of the radio frequency integrated module 1 to Bluetooth transmission mode, and controls the radio frequency front-end module 2 to select the radio frequency transmission path, so that the transmitter 3 of the radio frequency integrated module 1 is connected to the antenna 2, that is, the Bluetooth transmission link 21 is connected, so that the Bluetooth module can receive data sent by the link 2 through Bluetooth.

[0112] The mobile terminal connects to the transmission link 22, including: enabling the transmitter 4 of the RF integrated module 1 and controlling the RF front-end module 2 to select the RF transmission path, thereby connecting the Bluetooth transmission link 2.

[0116] Specifically, the mobile terminal activates the cellular communication link 4 by: enabling the transmitting end 5 of the RF integrated module 2, controlling the ports B3 and B2 of the switch module 2 to be turned on, and controlling the RF front-end module 3 to select the RF transmission path, thereby activating the cellular transmission link 4. In this case, the cellular module can transmit data through the cellular transmission link 4. Alternatively, the mobile terminal enables the receiving end 5 of the RF integrated module 2, controls the ports B3 and B2 of the switch module 2 to be turned on, and controls the RF front-end module 3 to select the RF reception path, thereby activating the cellular reception link 4. In this case, the cellular module can receive data through the cellular reception link 4.

[0117] Specifically, the mobile terminal shuts down the cellular communication link 4 by: disabling the transmitter 5 of the RF integrated module 2, shutting down the path of the RF front-end module 3, and disconnecting ports B3 and B2 of the switch module 2, thereby disconnecting the cellular transmission link 4. Additionally, the mobile terminal disables the receiver 5 of the RF integrated module 2, shuts down the path of the RF front-end module 3, and disconnects ports B3 and B2 of the switch module 2, thereby disconnecting the cellular reception link 4.

[0118] In S507, the mobile terminal can shut down cellular communication link 4 and switch from enabling Bluetooth communication link 1 (or Bluetooth communication link 2) to enabling Bluetooth communication link 3. Specifically, in the scenario of receiving data, the mobile terminal shuts down the Bluetooth receiving links in Bluetooth communication links 1 and 2, and enables the Bluetooth receiving link in Bluetooth communication link 3; in the scenario of sending data, the mobile terminal shuts down the Bluetooth transmitting links in Bluetooth communication links 1 and 2, and enables the Bluetooth transmitting link in Bluetooth communication link 3.

[0119] Specifically, the mobile terminal shuts down the Bluetooth receiving links in Bluetooth communication link 1 and Bluetooth communication link 2, including: the mobile terminal shuts down Bluetooth receiving link 11 and Bluetooth receiving link 21.

[0120] The mobile terminal shutting down the Bluetooth receiving link 11 includes: the mobile terminal configuring the receiver 1 (which can be referred to as the second receiver) of the radio frequency integrated module 1 to wireless fidelity mode, or disabling the receiver 1 of the radio frequency integrated module 1.

[0121] The mobile terminal shuts down the Bluetooth receiving link 21, including: the mobile terminal configures the receiver 3 (which may be referred to as the third receiver) of the radio frequency integrated module 1 to wireless fidelity mode, or disables the receiver 3 of the radio frequency integrated module 1.

[0122] Specifically, the mobile terminal shuts down the Bluetooth transmission links in Bluetooth communication link 1 and Bluetooth communication link 2, including: the mobile terminal shuts down Bluetooth transmission link 11, Bluetooth transmission link 12, Bluetooth transmission link 21, and Bluetooth transmission link 22.

[0126] The mobile terminal shuts down the Bluetooth transmission link 22, including: the mobile terminal disables the transmitter 4 of the radio frequency integrated module 1.

[0127] In one example, if port B3 of switch module 2 is connected to port B2 of switch module 2, the pass flag of cellular communication link 4 is represented by the value 1; if port B3 of switch module 2 is not connected to port B2 of switch module 2, the pass flag of cellular communication link 4 is represented by the value 2.

[0128] Figure 7 This illustration shows one of the structural schematic diagrams of a switching circuit provided in an embodiment of this application.

[0129] In one example, combining Figure 6 ,like Figure 7 As shown, switch module 1 includes switch 1 (i.e., the first switch) and switch 2 (i.e., the second switch). For example, switch 1 and switch 2 can each be a single-pole double-throw switch. Port a11 of switch 1 is connected to the transmitting end 2 of RF integrated module 1, port a13 of switch 1 is connected to RF front-end module 1, port a12 of switch 1 is connected to port a21 of switch 2, port a22 of switch 2 is connected to the receiving end 2 of RF integrated module 1, and port a23 of switch 2 is connected to port B1 of switch module 2.

[0132] Figure 8 The second schematic diagram shows a switching circuit provided in an embodiment of this application.

[0133] In one example, combining Figure 6 and Figure 7 ,like Figure 8 As shown, switch module 2 includes switch 3 (i.e., the third switch) and switch 4 (i.e., the fourth switch). For example, switch 3 and switch 4 can each be a three-pole three-throw switch. Port b11 of switch 3 is connected to port A3 of switch module 1, port b12 of switch 3 is connected to port b21 of switch 4, port b22 of switch 4 is connected to antenna 3, and port b23 of switch 4 is connected to the receiver 5 of RF integrated module 2 and the transmitter 5 of RF integrated module 2 through RF front-end module 3. Therefore, port b11 of switch 3 is port B1 of switch module 2, port b22 of switch 4 is port B2 of switch module 2, and port b23 of switch 4 is port B3 of switch module 2.

[0134] Based on this, port B3 of the mobile terminal control switch module 2 and port B2 of the switch module 2 are connected, including: port b23 and port b22 of the mobile terminal control switch 4 are connected.

Similarly, port b21 of switch 4 can be referred to as the first port of switch 4, port b22 of switch 4 can be referred to as the second port of switch 4, and port b23 of switch 4 can be referred to as the third port of switch 4.

[0137] Figure 9 This is a second schematic diagram of the structure of a communication circuit provided in an embodiment of this application.

[0138] Furthermore, such as Figure 9 As shown, the communication circuit provided in this embodiment of the application also includes switch 5 (which can be referred to as the fifth switch). For example, switch 5 can be a single-pole double-throw switch. Port c11 of switch 5 is connected to port b11 of switch 3, and port c12 of switch 5 is connected to port a23 of switch 2. In addition, when the mobile terminal needs to connect the Bluetooth communication link 3, it is also necessary to control the connection between port c11 and port c12 of switch 5.

[0139] It should be noted that, Figure 9 In the above text, port TX1_HB of RF integrated module 2 is the transmitting end 5 (TX5), and port PRX_MHB of RF integrated module 2 is the receiving end 5 (RX5). Figure 9 The other devices connected to the RF integrated module 2 are the devices required for the operation of the cellular module. For details, please refer to the relevant technical descriptions, which will not be elaborated here.

[0140] S508: The mobile terminal determines whether the received signal strength 2 is greater than the received signal strength 1.

[0141] If the received signal strength 2 is greater than the received signal strength 1, it indicates that the Bluetooth module's performance when transmitting data through antenna 3 is better than its performance when transmitting data through antenna 1 (or antenna 2). Therefore, the mobile terminal can maintain its current state, i.e., the mobile terminal can execute S509 as described below. If the received signal strength 2 is less than the received signal strength 1, it indicates that the Bluetooth module's performance when transmitting data through antenna 1 (or antenna 2) is better than its performance when transmitting data through antenna 3. Therefore, the mobile terminal can execute S501 as described above.

[0142] S509, the mobile terminal maintains control of the Bluetooth module to transmit data via antenna 3.

[0143] When the priority of the Bluetooth module's service is higher than that of the cellular module's service, the mobile terminal maintains control over the Bluetooth module to transmit data through antenna 3. This sacrifices some performance from the cellular module but significantly improves the Bluetooth module's performance, ensuring that the Bluetooth module can successfully execute the higher-priority task.

[0144] S510: The mobile terminal determines whether the Bluetooth module is working.

[0145] The mobile terminal can read the flag bit 1 in the Bluetooth module to determine whether the Bluetooth module is working. If the Bluetooth module is still working, the mobile terminal can continue to execute S501 as described above. For example, the mobile terminal can continue to execute S501 after a preset time. If the Bluetooth module is not working, the mobile terminal can execute S511 as described below.

[0146] S511, The mobile terminal controls the Bluetooth module to stop transmitting data through antenna 3.

[0147] In one example, the mobile terminal controls the Bluetooth module to stop transmitting data through antenna 3, including: the mobile terminal shutting down Bluetooth communication link 3. Specifically, the mobile terminal can disconnect the connection between ports A1 and A3 of switch module 1, disconnect the connection between ports B1 and B2 of switch module 2, and disable the transmitter 2 of RF integrated module 1, thereby shutting down Bluetooth transmission link 3; or, the mobile terminal can disconnect the connection between ports A2 and A3 of switch module 1, disconnect the connection between ports B1 and B2 of switch module 2, and disable the receiver 2 of RF integrated module 1, thereby shutting down Bluetooth reception link 3. This reduces the power consumption of the mobile terminal.

[0148] It should be noted that the above S501-S511 can be executed by the mobile terminal's processor, such as an application processor (AP) or a baseband processor (BP), and this article does not restrict this.
