The MIPI master module 324 is configured to convert an MIPI command (such as a second MIPI command involved later) from the controller 322 from the on-chip bus format to the MIPI bus format and transmit same to the second FEM 35.

The processor 31 can acquire communication state information of the first FEM 34, such as whether it performs Wi-Fi communication (or performs Wi-Fi communication or Bluetooth communication). The processor 31 can also acquire communication state information of the second FEM 35, such as whether it performs cellular communication. The processor 31 can also transmit a first control command or a second control command (as specifically described later) to the controller 322 in the switching circuit 32 through the SPI module 321 according to the communication state information of the first FEM 34, to control the second FEM 35 to switch between a cellular communication state and a Bluetooth communication state through the switching circuit 32.

The controller 322 is configured to control the bypass gating circuit 325 to switch between a bypass mode and a non-bypass mode according to the first control command or second control command from the processor 31.

Specifically, the wireless communication circuit can perform a Bluetooth communication switching method described in this application, and as shown in FIG. 4, the method includes the following steps:

In S101, a processor 31 acquires communication state information of a first FEM 34.

The communication state information of the first FEM 34 is used for indicating whether the first FEM 34 performs Wi-Fi communication, or the communication state information of the first FEM 34 is used for indicating whether the first FEM 34 performs Wi-Fi communication or performing Bluetooth communication.

In S102, when the communication state information of the first FEM 34 indicates that the first FEM 34 performs Wi-Fi communication (or referred to as establishing a Wi-Fi connection), the processor 31 transmits a first control command to a controller 322 in a switching circuit 32.

The first control command is used for controlling the switching circuit 32 to detect whether an MDM 33 transmits an MIPI command to a second FEM 35. When the MDM 33 does not transmit an MIPI command to the second FEM 35, the switching circuit 32 controls the second FEM 35 to perform Bluetooth communication.

As shown in S1021-S1025 in FIG. 5, in a bypass mode, when the controller 322 in the switching circuit 32 receives the first control command from the processor 31, the controller 322 configures a mode switching register to a non-bypass mode and controls a bypass gating circuit 325 to switch to the non-bypass mode. The controller 322 controls the bypass gating circuit 325 to conduct an MIPI slave module 323 with the MDM 251, and to conduct an MIPI master module 324 with the second FEM 35. The controller 322 detects whether the MDM 251 transmits an MIPI command to the second FEM 35 through the MIPI slave module 323. When it is detected that the MDM 251 does not transmit an MIPI command to the second FEM 35 (that is, the MIPI bus is idle), the controller 322 transmits a first MIPI command to the second FEM 35 through the MIPI master module 324. When it is detected that the MDM 251 transmits an MIPI command to the second FEM 35, it continues to wait until the MIPI bus is idle. The detected MIPI command from the MDM 251 may be any MIPI command. The first MIPI command is used for instructing the second FEM 35 to perform Bluetooth communication. That is to say; during the period that the MDM 251 does not transmit an MIPI command to the second FEM 35, the controller 322 switches the second FEM 35 from a cellular communication state to a Bluetooth communication state to avoid competing with the MDM 251 for the MIPI bus, thus avoiding transmission errors.

After the controller 322 transmits the first MIPI command to the second FEM 35 through the MIPI master module 324 to instruct the second FEM 35 to perform Bluetooth communication, the controller 322 continues to receive and cache an MIPI command from the MDM 251 through the MIPI slave module 323. When the controller 322 controls the second FEM 35 to switch back to the Bluetooth communication state, the cached MIPI command from the MDM 251 is transmitted to the second FEM 35 through the MIPI master module 324, so that the control logic between the MDM 251 and the second FEM 35 remains consistent before and after switching.

In addition, due to unstable Wi-Fi connections in certain scenarios, in order to prevent frequent switching of Bluetooth communication between the first FEM 34 and the second FEM 35, the processor 31 may determine whether to switch Bluetooth communication according to the time that the first FEM 34 performs Wi Fi communication. Alternatively; the processor 31 may determine whether to switch Bluetooth communication according to the number of times that the first FEM 34 switches between performing Wi-Fi communication and skipping performing Wi-Fi communication within preset time.

In a possible implementation, when the communication state information of the first FEM 34 indicates that the first FEM 34 performs Wi-Fi communication, the processor 31 transmits a first control command to the controller 322 in the switching circuit 32 after preset time (for example, one minute). That is, after the electronic device is stably connected to the Wi-Fi connection for preset time, the processor 31 transmits a first control command to the controller 322 in the switching circuit 32. The advantages of this solution are that determination conditions are simple and frequent switching will not occur from beginning to end.

In another possible implementation, when the communication state information of the first FEM 34 indicates that the first FEM 34 performs Wi-Fi communication and the number of times that the first FEM 34 switches between performing Wi-Fi communication and skipping performing Wi-Fi communication within first preset time (for example, 10 seconds) is less than a number threshold (for example, three times), the processor 31 transmits the first control command to the controller 322 in the switching circuit 32. When the number of times that the first FEM 34 switches between performing Wi-Fi communication and skipping performing Wi-Fi communication within the first preset time is greater than or equal to the number threshold, the processor 31 acquires the communication state information of the first FEM 34 after second preset time (for example, five minutes), so as to determine again whether to transmit the first control command. The advantage of this solution is that it can detect more quickly, switch the state as soon as possible after connecting to Wi-Fi, and provide a better experience.

Since the electronic device can support Bluetooth communication (or pairing) with multiple other devices, the processor 31 can switch all or some of Bluetooth communication from the first FEM 34 to the second FEM 35 to improve the quality of Bluetooth communication. Exemplarily, as shown in FIG. 6, the improvement of the quality of Bluetooth communication may be indicated by the change of the Bluetooth icon in the state bar of the electronic device from A to B, and the improvement of the quality of Bluetooth communication may also be indicated by the change of the Bluetooth icon from C to D in the drop-down menu, where A and C represent ordinary Bluetooth communication functions, and B and D represent enhanced Bluetooth communication functions. As shown in FIG. 7, a Bluetooth pairing interface can be enabled by clicking on the triangle icon next to the Bluetooth icon in the drop-down menu, which displays different Bluetooth devices connected through different antennas. As shown in FIG. 8, whether a Bluetooth enhancement function switch is turned on may be displayed in a Bluetooth settings menu. When the Bluetooth enhancement function switch is turned on, the electronic device can perform the Bluetooth communication switching method according to this application, and can display different Bluetooth devices connected through different antennas. When the Bluetooth enhancement function switch is turned off, the electronic device does not perform the Bluetooth communication switching method according to this application.

In S103, when the communication state information of the first FEM 34 indicates that the first FEM 34 does not perform Wi-Fi communication (or referred to as disconnecting a Wi-Fi connection), the processor 31 transmits a second control command to the controller 322 in the switching circuit 32.

The second control command is used for controlling the switching circuit 32 to detect whether the MDM 33 transmits an MIPI command to the second FEM 35. When the MDM 33 does not transmit an MIPI command to the second FEM 35, the switching circuit 32 directly conducts the MDM 33 with the second FEM 35, so that the MDM 33 controls the second FEM 35 to perform cellular communication.

As shown in S1031-S1034 in FIG. 5, in the non-bypass mode, when the controller 322 in the switching circuit 32 receives the second control command from the processor 31, the controller 322 configures the mode switching register to the bypass mode and controls the bypass gating circuit 325 to switch to the bypass mode. At this time, the controller 322 detects whether the MDM 251 transmits an MIPI command to the second FEM 35 through the MIPI slave module 323. When it is detected that the MDM 251 does not transmit an MIPI command to the second FEM 35 (that is, the MIPI bus is idle), the controller 322 controls the bypass gating circuit 325 to directly conduct the MDM 251 with the second FEM 35, and transmits a second MIPI command to the second FEM 35 through the MIPI master module 324. The second MIPI command is used for instructing the second FEM 35 to perform cellular communication. Therefore, the MDM 251 can control the second FEM 35 to perform cellular communication. When it is detected that the MDM 251 transmits an MIPI command to the second FEM 35, it continues to wait until the MIPI bus is idle. That is to say; during the period that the MDM 251 does not transmit an MIPI command to the second FEM 35, the controller 322 switches the second FEM 35 from a Bluetooth communication state to a cellular communication state to avoid competing with the MDM 251 for the MIPI bus, thus avoiding transmission errors.

After the controller 322 transmits the second MIPI command to the second FEM 35 through the MIPI master module 324 to instruct the second FEM 35 to perform cellular communication, it also needs to transmit the previously cached MIPI command from the MDM 251 to the second FEM 35 through the MIPI master module 324, so that the control logic between the MDM 251 and the second FEM 35 remains consistent before and after switching.

In the wireless communication circuit, the Bluetooth communication switching method and the electronic device provided in the embodiments of this application, the first FEM supports wireless fidelity Wi-Fi communication or Bluetooth communication; when the first FEM performs Wi-Fi communication and the MDM does not transmit an MIPI command to the second FEM, the second FEM is controlled to perform Bluetooth communication, thus switching some or all of Bluetooth communication of the first FEM to a relatively idle second FEM, preventing time-division multiplexing of Wi-Fi communication and Bluetooth communication from occupying resources for Bluetooth communication, and improving the communication quality of Bluetooth communication.
