Communication method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method and apparatus.

Background

The beidou short message communication service is one of the features that the beidou satellite navigation system is different from other global positioning navigation systems such as a Global Positioning System (GPS) in the united states, a global navigation satellite system (GLONASS) in russia and the like, and is particularly suitable for positioning and communicating in areas where mobile communication is uncovered or where a communication system is damaged, such as oceans, deserts, grasslands, unmanned areas and the like. The Beidou No. three short message system upgrades the technical system, and realizes the separation of civil and military signals. At present, on the premise that the military requirements are completely met, some necessary resources of the Beidou system are opened for civilian use, namely, the common mobile phone can also receive and send Beidou short messages through the Beidou chip. The third beidou covers China mainly, and the third beidou covers China, asia-Tai and the whole world. The service capacity of the Beidou No. three can reach 1200 ten thousand times of inbound and 50 ten thousand times of outbound every hour. When the Beidou system interacts with the electronic equipment, the transmitting power of the electronic equipment is 3-5W.

Because the receiving frequency band of the Beidou short message and the 2.4GHz frequency range of wireless fidelity (Wi-Fi) are crossed, when the Beidou short message function and the Wi-Fi function are simultaneously started by a common mobile phone, beidou short message service and the Wi-Fi service can interfere with each other, and the communication quality of the Beidou short message service and the Wi-Fi service is influenced.

Disclosure of Invention

The application provides a communication method and a communication device, which realize that when an electronic device detects that a Wi-Fi chip and a Beidou short message chip work simultaneously, if the electronic device detects that the Wi-Fi service can interfere with the Beidou short message service, namely, when the electronic device detects that the Wi-Fi chip works on a preset interference channel (for example, a channel 9-channel 13 of a 2.4GHz frequency band of Wi-Fi), the electronic device can control the Wi-Fi chip to avoid the Beidou short message chip through the following avoidance schemes. Wherein, the avoidance scheme may include: (1) The Wi-Fi chip suspends work when the Beidou short message chip sends or receives signals. (2) The frequency of operation of the communication connection used by the Wi-Fi service of the electronic device 100 is switched. (3) And switching the antenna used by the Wi-Fi chip to the antenna which is farthest away from the antenna used by the Beidou short message chip. (4) When the Wi-Fi chip uses two or more antennas to send and receive signals, the antennas used by the Wi-Fi chip are reduced. Therefore, the electronic device 100 can reduce the mutual influence of the Wi-Fi 2.4GHz frequency band signal and the Beidou short message signal, and improve the working performance of the Beidou short message chip.

In a first aspect, the present application provides a communication method, including: the electronic equipment detects that the Wi-Fi chip and the Beidou short message chip work simultaneously.

When the electronic equipment detects that the Wi-Fi chip works in the preset interference channel, the electronic equipment controls the Wi-Fi chip to avoid the Beidou short message chip.

According to the communication method, when the Wi-Fi chip and the Beidou short message chip work simultaneously and the Wi-Fi chip is detected to work in the preset interference channel, the Wi-Fi chip is controlled to avoid the Beidou short message chip. Therefore, the mutual influence of the Wi-Fi chip and the Beidou short message chip can be reduced, and the working performance of the Beidou short message chip is improved.

In a possible implementation manner, the electronic device controls the Wi-Fi chip to avoid the beidou short message chip, and the method specifically includes: the electronic equipment controls the Wi-Fi chip to pause working when the Beidou short message chip receives/sends signals.

Thus, since the overhead of the beidou short message service is relatively large, the time for the electronic device 100 to execute the beidou short message service is generally relatively short. The Wi-Fi chip is controlled to pause work in the period of receiving/sending signals by the Beidou short message chip. The Wi-Fi service can not influence the Beidou short message service, and meanwhile, the Wi-Fi service can not greatly reduce the transmitting power to avoid the Beidou short message service in the starting period of the Beidou short message function, so that the Wi-Fi service can be finished under smaller influence.

In one possible implementation manner, the electronic device detects that the Wi-Fi chip operates before the preset interference channel, and the method further includes: and the Wi-Fi chip sends the working frequency band information to the Beidou short message chip. The electronic equipment detects that the Wi-Fi chip works in a preset interference channel, and the method specifically comprises the following steps:

the Beidou short message chip judges that the Wi-Fi chip works in a preset interference channel based on the frequency band information.

Therefore, whether the Wi-Fi chip is in the preset interference channel or not is judged through the Beidou short message chip, and the Beidou short message chip can inform the Wi-Fi chip to execute an avoidance scheme when the working of the Wi-Fi chip in the preset interference channel is judged as soon as possible.

In a possible implementation manner, the electronic device controls the Wi-Fi chip to suspend working when the big dipper short message chip receives/sends a signal, and the method specifically includes: and when the Wi-Fi chip receives the signal, the signal transmission is suspended.

Therefore, the frequency range of the Beidou short message chip for receiving signals is crossed with the frequency range of the preset interference channel, and the Wi-Fi chip is controlled to pause signal sending when the Beidou short message chip receives signals, so that the influence of the Wi-Fi service on the Beidou short message service can be reduced.

In a possible implementation manner, when the Wi-Fi chip receives a signal, the Beidou short message chip suspends sending the signal, and the method specifically comprises the following steps: and when the Beidou short message chip starts to receive signals, transmitting a Beidou reception start notice to the Wi-Fi chip, wherein the Beidou reception start notice is used for triggering the Wi-Fi chip to suspend sending signals.

In a possible implementation manner, after the Beidou short message chip sends a Beidou reception start notification to the Wi-Fi chip when the Beidou short message chip starts to receive signals, the method further includes: and when the Beidou short message chip finishes receiving the signals, transmitting a Beidou reception finishing notice to the Wi-Fi chip, wherein the Beidou reception finishing notice is used for triggering the Wi-Fi chip to start to transmit the signals.

Therefore, the Wi-Fi chip is informed of avoiding when the Beidou short message chip works, and the Wi-Fi chip can be controlled to pause signal receiving when the Beidou short message chip starts to receive signals as soon as possible. And the Wi-Fi chip can be controlled to continue to receive signals when the Beidou short message chip finishes receiving the signals as soon as possible.

In a possible implementation manner, after the electronic device detects that the Wi-Fi chip and the beidou short message chip work simultaneously, the method further includes: the electronic equipment judges the priority of the Wi-Fi service and the Beidou short message service. When the electronic equipment detects that the Wi-Fi chip works in a preset interference channel, the electronic equipment controls the Wi-Fi chip to avoid the Beidou short message chip, and the method specifically comprises the following steps:

after the electronic equipment judges that the priority of the Beidou short message service is higher than that of the Wi-Fi service, when the electronic equipment detects that the Wi-Fi chip works in a preset interference channel, the electronic equipment controls the Wi-Fi chip to avoid the Beidou short message chip.

In a possible implementation manner, after the electronic device detects that the Wi-Fi chip and the beidou short message chip work simultaneously, the electronic device judges the priority of the Wi-Fi service and the beidou short message service. When the electronic equipment judges that the priority of the Wi-Fi service is higher than that of the Beidou short message service and detects that the Wi-Fi chip works in a preset interference channel, the electronic equipment controls the Beidou short message chip to avoid the Wi-Fi chip.

Therefore, by judging the priority of the Wi-Fi service and the Beidou short message service, the chip executing the low-priority service is controlled to avoid the chip executing the high-priority service, and the interference of the low-priority service on the high-priority service can be weakened.

In a possible implementation manner, the electronic device controls the Wi-Fi chip to avoid the beidou short message chip, and the method specifically comprises the following steps: and the Wi-Fi chip disconnects the communication connection on the preset interference channel.

The electronic equipment establishes communication connection in a frequency range outside the preset interference channel, and sends or receives signals of the Wi-Fi service through the communication connection in the frequency range outside the preset interference channel.

Therefore, the electronic equipment can try to switch the frequency range of the communication connection of the Wi-Fi service at first, so that the frequency ranges of the Wi-Fi service and the Beidou short message service are not crossed, and the performance of the Wi-Fi service and the Beidou short message service can be guaranteed to the maximum extent. When the frequency range of the Wi-Fi service cannot be switched, the electronic device 100 may avoid the beidou short message service by using the Wi-Fi service through the above-mentioned pause mode, so as to reduce the mutual influence between the Wi-Fi service and the beidou short message service.

In a possible implementation manner, the electronic device establishes a communication connection in a frequency range outside a preset interference channel, and the method specifically includes: the electronic device establishes a communication connection on the 5GHz frequency band. Alternatively, the electronic device establishes a cellular communication connection. Or the electronic equipment establishes communication connection on channels except the preset interference channel on the 2.4GHz frequency band.

In a possible implementation manner, the electronic device controls the Wi-Fi chip to avoid the beidou short message chip, and the method specifically includes: the electronic equipment detects that the Wi-Fi chip receives or sends signals by using M antennas, wherein M is a positive integer larger than 1. The Wi-Fi chip receives or sends signals by using N antennas, wherein N is a positive integer smaller than M.

The more the number of the antennas used by the Wi-Fi service is, the greater the interference on the Beidou short message service is. Therefore, the influence of the Wi-Fi service on the Beidou short message service can be effectively reduced by reducing the number of antennas used by the Wi-Fi service.

In a possible implementation manner, the electronic device controls the Wi-Fi chip to avoid the beidou short message chip, and the method specifically includes: the Wi-Fi chip sends or receives signals by using an antenna which is farthest from the antenna of the Beidou short message chip in the Euclidean distance.

Therefore, the farther the distance between the antenna used by the Wi-Fi chip and the antenna used by the Beidou short message chip is, the higher the isolation between the antennas is. The higher the isolation between the antennas, the less interference is generated with each other. The influence of Wi-Fi service on the Beidou short message service can be effectively reduced by using the antenna which is farthest away from the antenna used by the Wi-Fi chip and the Beidou short message chip to work.

In one possible implementation, the Wi-Fi chip receives or transmits signals using N antennas, and the method specifically includes: the Wi-Fi chip sends or receives signals by using N antennas which are farthest from the antenna of the Beidou short message chip in Euclidean distance.

In a possible implementation manner, the electronic device controls the Wi-Fi chip to avoid the beidou short message chip, and the method specifically includes: and the Wi-Fi chip disconnects the communication connection on the preset interference channel. The electronic equipment establishes communication connection on channels except a preset interference channel on the 2.4GHz frequency band.

In a possible implementation manner, after the electronic device establishes a communication connection on a channel other than a preset interference channel on the 2.4GHz band, the method further includes: and the Wi-Fi chip sends or receives signals by using an antenna which is farthest from the antenna of the Beidou short message chip in Euclidean distance.

In a possible implementation manner, after the electronic device establishes a communication connection on a channel other than a preset interference channel on the 2.4GHz band, the method further includes: the electronic equipment detects that the Wi-Fi chip receives or sends signals by using M antennas, wherein M is a positive integer larger than 1. The Wi-Fi chip receives or sends signals by using N antennas, wherein N is a positive integer smaller than M.

Therefore, the interference of Wi-Fi service on the Beidou short message service can be further reduced by combining a plurality of avoidance schemes.

In a possible implementation manner, after the electronic device detects that the Wi-Fi chip operates on the preset interference channel, the method further includes: the Wi-Fi chip is reduced from a default transmit power (e.g., 16 dBm) to a preset operating power (e.g., 10 dBm).

In a possible implementation manner, the Wi-Fi chip can adjust the transmission power to the preset working power when the big dipper short message chip receives a signal, and work with the default transmission power at other times.

Therefore, the interference of the Wi-Fi service to the Beidou short message service can be reduced, and meanwhile, the influence of the Beidou short message service on the Wi-Fi service is reduced.

The one or more memories are coupled to the one or more processors and the one or more memories are configured to store computer program code comprising computer instructions that, when executed by the one or more processors, cause the electronic device to perform the method of communication in any of the possible implementations of any of the aspects described above.

Detailed Description

The technical solutions in the embodiments of the present application will be described in detail and clearly with reference to the accompanying drawings. Wherein in the description of the embodiments of the present application, "/" indicates an inclusive meaning, for example, a/B may indicate a or B; the "and/or" in the text is only an association relation describing the association object, and indicates that three relations may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone.

In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as implying or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of embodiments of the application, unless stated otherwise, "plurality" means two or more.

The Beidou short message satellite comprises 3 geosynchronous orbit (GEO) satellites, 36000km from the ground, and the positions of the three satellites are respectively 80 degrees of east longitude, 110.5 degrees of east longitude and 140 degrees of east longitude. The Beidou short message satellite can ensure that the area in the rectangular frame shown in the figure 1 can receive the short message service through directional wave beams. The service types of the short message can include three types, namely short message communication, position reporting and emergency rescue. Wherein, the short message communication can be communicated with other devices under the condition of no network. Location reporting may be used to share location information. The emergency rescue can be directly connected with a national emergency rescue center to obtain emergency rescue service. The Beidou short message service needs the support of a Beidou system.

For example, fig. 2 is a schematic diagram illustrating a connection scenario in which the electronic device 100 accesses a beidou system according to an embodiment of the present application, where the scenario may include the electronic device 100 and a plurality of other devices (e.g., a beidou short message satellite, a receiving station/transmitting station, a data center, and the like). The electronic device 100 has a function of transmitting (receiving) a signal of the beidou short message. The inbound is a process in which the electronic device 100 sends a signal to a data center. First, the electronic device 100 sends a signal to the beidou short message satellite, which forwards the signal to a receiving station, which sends the signal to a data center for relevant processing (e.g., forwarding the signal to an operator network, etc.). Outbound is the process by which the data center sends signals to the electronic device 100. Wherein, data center can send the signal to the transmitting station, and the transmitting station sends for big dipper short message satellite, and big dipper short message satellite sends the signal to electronic equipment 100 again. Thus, the electronic device 100 can communicate with the beidou short message satellite through the beidou short message satellite.

Fig. 3 shows a schematic diagram of a frequency distribution provided by an embodiment of the present application. As shown in fig. 3, the frequency range of the beidou short message reception is 2.4835GHz to 2.5GHz. The frequency range of the 2.4GHz band of Wi-Fi is from 2.402GHz to 2.492GHz. The frequency range of the Wi-Fi 2.4GHz frequency band is crossed with the frequency range of the Beidou short message (as shown by a slash area in the figure), and signals of partial channels of the Wi-Fi 2.4GHz frequency band can interfere with the signals of the Beidou short message.

In a possible implementation manner, the electronic device 100 with the beidou short message function can reduce the transmission power of a partial channel of the Wi-Fi in the 2.4GHz band, and avoid affecting signals in the beidou short message band.

Fig. 4 is a schematic diagram of power reduction provided in an embodiment of the present application. Figure 4 shows the power droop for channel 11 and channel 13 in the 2.4GHz band for Wi-Fi under various test methods after adjustments to the Wi-Fi transmit power are made based on the requirements of the "Notification about adjusting the 2.4GHz band transmit power limit and related problems". When the radio management committee (uncommitted) test method is used, the transmission power of the channel 11 is reduced by 7.5dB and the transmission power of the channel 13 is reduced by 17.2dB under the condition that the test limit is-40 dBm/MHz. In order to avoid influence on the frequency band of the Beidou short message, the reduction amplitude of the transmitting power from the channel 11 to the channel 13 of the Wi-Fi 2.4GHz frequency band is larger than 7dB. Thus, the power reduction amplitude of a part of channels in the 2.4GHz frequency band of the Wi-Fi is too large. After the Beidou short message function is turned on, even if the electronic device 100 does not process the service of the Beidou short message, the transmission power of the Wi-Fi 2.4GHz frequency band is still in a greatly reduced state, and the quality of the signal of the Wi-Fi 2.4GHz frequency band sent or received by the electronic device 100 is seriously affected. Therefore, as long as the Beidou short message function of the electronic equipment 100 is turned on, the transmission power of signals of 2.4GHz frequency band of Wi-Fi of the electronic equipment 100 is reduced to ensure that the Beidou short message is not influenced, and the communication performance of the Wi-Fi is seriously influenced.

The embodiment of the application provides a communication method. When the electronic device 100 detects that the Wi-Fi chip and the beidou short message chip work simultaneously, if the electronic device 100 detects that the Wi-Fi service interferes with the beidou short message service, that is, when the electronic device 100 detects that the working frequency of the Wi-Fi chip is within the frequency range of a preset interference channel (for example, channel 9-channel 13 of 2.4GHz frequency band of Wi-Fi), the electronic device 100 may execute one or more of the following avoidance schemes for avoiding the beidou short message chip by the Wi-Fi chip. Wherein, the avoidance scheme may include: (1) The Wi-Fi chip suspends work when the Beidou short message chip sends or receives signals. (2) The frequency of operation of the communication connection used by the Wi-Fi service of the electronic device 100 is switched. (3) And switching the antenna used by the Wi-Fi chip, namely switching the antenna used by the Wi-Fi chip to the antenna which is farthest away from the antenna used by the Beidou short message chip. (4) When the Wi-Fi chip uses two or more antennas to send and receive signals, the antennas used by the Wi-Fi chip are reduced. Therefore, the electronic device 100 can reduce the mutual influence of the Wi-Fi 2.4GHz frequency band signal and the Beidou short message signal, and improve the working performance of the Beidou short message chip.

The kernel layer processes the touch operation into an original input event (including touch coordinates, a time stamp of the touch operation, and other information). The raw input events are stored at the kernel layer. And the application program framework layer acquires the original input event from the kernel layer and identifies the control corresponding to the input event. Taking the touch operation as a touch click operation, and taking a control corresponding to the click operation as a control of a camera application icon as an example, the camera application calls an interface of an application framework layer, starts the camera application, further starts a camera drive by calling a kernel layer, and captures a still image or a video through the camera 193.

A chip system 700 provided by an embodiment of the present application is described next.

Illustratively, as shown in fig. 7, the chip system 700 may include: the system comprises an application processor 701, a Beidou short message chip 702 and a Wi-Fi chip 703. The chip system 700 may be applied to the electronic device 100. The electronic apparatus 100 may execute the avoidance scheme (1) to the avoidance scheme (4) based on the chip system 700. Wherein:

the application processor 701 of the electronic device 100 may communicate with the beidou short message chip 702 through an interface (e.g., PCIE). The application processor 701 of the electronic device 100 may also communicate with the Wi-Fi chip 703 via an interface (e.g., PCIE, SDIO). The big dipper short message chip 702 and the Wi-Fi chip 703 may communicate through an interface (e.g., UART).

The application processor 701 may be configured to detect whether the beidou short message chip 702 and the Wi-Fi chip 703 are operating simultaneously.

For example, the application processor 701 may detect that the Wi-Fi chip and the beidou short message chip are working simultaneously by using the following methods: (1) After receiving the input of the user for turning on the Wi-Fi function and the beidou short message function, the electronic device 100 determines that the Wi-Fi chip 703 and the beidou short message chip 702 work simultaneously before receiving the input of the user for turning off the Wi-Fi function or the beidou short message function. (2) The big dipper short message chip and Wi-Fi chip can send the information of beginning work to electronic equipment 100 when beginning work. When the job is ended, information for ending the job is transmitted to the electronic apparatus 100. When the electronic device 100 receives information that the Wi-Fi chip and the beidou short message chip start to work and does not receive information that the Wi-Fi chip or the beidou short message chip finishes working, it is determined that the Wi-Fi chip 703 and the beidou short message chip 702 work simultaneously. (3) The electronic device 100 may acquire the operating states of the Wi-Fi chip and the beidou short message chip at a preset time interval (e.g., 1 ms). When the electronic device 100 detects that both the Wi-Fi chip and the Beidou short message chip work, an avoidance scheme is executed.

It should be noted that the above methods for detecting whether the beidou short message chip 702 and the Wi-Fi chip 703 operate simultaneously are only some examples provided in the embodiments of the present application. In practical application, the electronic device 100 may also detect whether the beidou short message chip 702 and the Wi-Fi chip 703 operate simultaneously through other methods, which is not limited herein.

When the application processor 701 determines that the big dipper short message chip 702 and the Wi-Fi chip 703 work simultaneously, the Wi-Fi chip 703 may execute one or more of the avoidance schemes (1) to (4) when detecting that the Wi-Fi chip 703 works in a preset interference channel.

After the application processor 701 determines that the beidou short message chip 702 and the Wi-Fi chip 703 work simultaneously, the application processor 701 may send a first avoidance notification to the Wi-Fi chip 703. The first avoidance notification may be used to trigger the Wi-Fi chip 703 to detect whether the Wi-Fi chip 703 operates on a predetermined interference channel (e.g., channel 9-channel 13 in the 2.4GHz band).

Specifically, when the Wi-Fi chip 703 detects that the Wi-Fi chip is working on a preset interference channel, the Wi-Fi chip 703 may execute an avoidance scheme. For example, the Wi-Fi chip 703 may suspend sending Wi-Fi signals when the beidou short message chip 702 receives signals. Alternatively, the Wi-Fi chip 703 may switch the frequency range in which the communication connection for Wi-Fi traffic operates, and so on.

Optionally, the Wi-Fi chip 703 may further detect whether the Wi-Fi chip 703 operates in a preset interference channel through the beidou short message chip 702. For example, after receiving the first avoidance notification, the Wi-Fi chip 703 may send the working frequency band information to the beidou short message chip 702, and the beidou short message chip 702 may notify the Wi-Fi chip 703 to suspend sending the Wi-Fi signal when determining that the Wi-Fi chip 703 is working on the preset interference channel based on the frequency band information and when receiving the beidou signal.

In a possible implementation manner, after the application processor 701 determines that the beidou short message chip 702 and the Wi-Fi chip 703 work simultaneously, the application processor 701 may further be configured to detect whether the Wi-Fi chip 703 works in a preset interference channel. When the application processor 701 detects that the Wi-Fi chip 703 operates on a preset interference channel, the Wi-Fi chip 703 may be notified to execute one or more of the avoidance schemes (1) to (4) described above.

Optionally, the application processor 701 may also be configured to determine priorities of a beidou short message service and a Wi-Fi service.

The application processor 701 may determine the priority levels of the Wi-Fi service and the beidou short message service according to pre-stored priority level information (for example, table 2) of the Wi-Fi service and the short message service.

If the application processor 701 determines that the Beidou short message service priority is higher than the Wi-Fi service, the application processor 701 may send a Beidou priority start notification to the Wi-Fi chip 703, and the Wi-Fi chip 703 may send the Beidou priority start notification to the Beidou short message chip 702. The Wi-Fi chip 703 avoids the Beidou short message chip 702. When the big dipper short message service or the Wi-Fi service is changed, the application processor 701 can send a big dipper priority end notification to the Wi-Fi chip 703, the Wi-Fi chip 703 can send the big dipper priority end notification to the big dipper short message chip 702, and the Wi-Fi chip 703 works with default power.

If the application processor 701 determines that the priority of the beidou short message service is lower than that of the Wi-Fi service, the application processor 701 may send a Wi-Fi priority start notification to the Wi-Fi chip 703, and the Wi-Fi chip 703 may send the Wi-Fi priority start notification to the beidou short message chip 702. The big dipper short message chip 702 dodges the Wi-Fi chip 703. When the big dipper short message service or the Wi-Fi service changes, the application processor 701 may send a Wi-Fi priority end notification to the Wi-Fi chip 703, the Wi-Fi chip 703 may send the Wi-Fi priority end notification to the big dipper short message chip 702, and the big dipper short message chip 702 operates at a default power.

The big dipper short message chip 702 may be used for communicating with a big dipper short message satellite. The Beidou short message chip 702 can also pause receiving the Beidou signal when the Wi-Fi chip 703 sends a signal after receiving the Wi-Fi priority start notification. When the Wi-Fi chip 703 receives a signal, the Beidou signal is suspended from being transmitted. The Beidou short message chip 702 can also judge whether the Wi-Fi chip 703 works in a preset interference channel when receiving frequency band information sent by the Wi-Fi chip 703. When the Beidou short message chip 702 judges that the Wi-Fi chip 703 works in a preset interference channel, the Beidou short message chip can inform the Wi-Fi chip 703 to suspend sending Wi-Fi signals when receiving Beidou signals. And the Wi-Fi chip 703 can be informed to suspend receiving Wi-Fi signals when the Beidou signal is sent.

The Wi-Fi chip 703 may be used to establish a Wi-Fi connection with an Access Point (AP) device and transmit data with the AP device via an antenna. The Wi-Fi chip 703 may also establish a Wi-Fi connection with other Station (STA) devices after starting the Wi-Fi hotspot function, and transmit data of the Wi-Fi hotspot mode service through the antenna and the STA devices. The Wi-Fi chip 703 may also operate in a Multiple Input Multiple Output (MIMO) mode, and receive and transmit signals through multiple antennas. The Wi-Fi chip can also work in a Single Input Single Output (SISO) mode, and receive and transmit signals through one antenna. The Wi-Fi chip 703 may also operate in a Dual Band Adaptive Concurrent (DBAC) mode, that is, a Wi-Fi connection in a 2.4GHz band and a Wi-Fi connection in a 5GHz band are established at the same time, and the Wi-Fi chip 703 may transmit or receive signals in the two bands.

The Wi-Fi chip 703 may also simultaneously operate in a DBAC mode and a MIMO mode, that is, a Wi-Fi connection in a 2.4GHz band and a Wi-Fi connection in a 5GHz band are simultaneously established, and the Wi-Fi chip 703 may transmit or receive signals in the two bands by using a plurality of antennas. The Wi-Fi chip 703 may also operate in a DBAC mode and a SISO mode simultaneously, that is, a Wi-Fi connection in a 2.4GHz band and a Wi-Fi connection in a 5GHz band are established simultaneously, and the Wi-Fi chip 703 may transmit or receive signals in both bands using one antenna.

The Wi-Fi chip 703 can also detect whether the Wi-Fi chip 703 is operating on a preset interference channel.

The Wi-Fi chip 703 may execute a plurality of avoidance schemes provided in the embodiment of the present application when detecting that the Wi-Fi chip 703 operates in a preset interference channel:

(1) The Wi-Fi chip 703 can send the frequency band information of Wi-Fi work to the Beidou short message chip 702. The Wi-Fi chip 703 is detected to work in a preset interference channel through the Beidou short message chip 702. The Wi-Fi chip 703 can suspend sending Wi-Fi signals when the Beidou short message chip 702 detects that the Wi-Fi chip 703 works in a preset interference channel and the Beidou short message chip receives Beidou signals. Further, the Wi-Fi chip 703 may suspend receiving the Wi-Fi signal when the big dipper short message chip sends the big dipper signal.

In this way, the beidou short message chip and the Wi-Fi chip of the electronic device 100 may exchange service information (e.g., a Wi-Fi priority start notification, a Wi-Fi priority end notification, frequency band information, a first avoidance suspension notification, a second avoidance suspension notification, etc.) quickly through the interface, and perform an avoidance operation more quickly.

(2) The Wi-Fi chip 703 may disconnect a Wi-Fi connection on a preset interference channel, establish a communication connection in a frequency range other than the preset interference channel, and receive or transmit a signal of a Wi-Fi service through the newly established communication connection.

(3) The Wi-Fi chip 703 may switch the antenna used to the antenna that is the farthest from the antenna used by the beidou short message chip 702.

(4) When the Wi-Fi chip 703 detects that the Wi-Fi chip 703 uses at least two antennas to transmit or receive Wi-Fi signals, the number of antennas used can be reduced.

Optionally, the Wi-Fi chip 703 may also reduce the transmit power. Further, the Wi-Fi chip 703 can reduce the transmission power of the Wi-Fi chip 703 and reduce the influence of the Wi-Fi service on the beidou short message service while executing the avoidance scheme.

In a possible implementation manner, when the big dipper short message chip 702 receives the big dipper signal, the transmission power of the Wi-Fi chip 703 is reduced. At times other than when the big dipper short message chip 702 receives the big dipper signal, the Wi-Fi chip 703 operates at a default power.

The Wi-Fi chip 703 may send the Wi-Fi priority start notification to the beidou short message chip 702 after receiving the Wi-Fi priority start notification. The Wi-Fi chip 703 can also inform the Beidou short message chip 702 to suspend receiving Beidou signals when sending Wi-Fi signals. When the Wi-Fi signal is received, the Beidou short message chip 702 is informed to suspend sending the Beidou signal.

In the chip system 700, messages between the Wi-Fi chip 703 and the beidou short message chip 702 can be forwarded through the application processor 701.

In this way, the electronic device 100 may reduce the mutual influence between the Wi-Fi service and the beidou short message service through the chip system 700.

An avoidance scheme provided by an embodiment of the present application will be described with reference to fig. 8-9. The avoidance scheme is the scheme that the Wi-Fi chip stops working during the period of transmitting and receiving signals by the Beidou short message chip.

In a possible implementation manner, when the electronic device 100 detects that both the Wi-Fi chip and the beidou short message chip are in the working state, if the electronic device 100 detects that the working frequency of the Wi-Fi chip is within the frequency range of the preset interference channel, the Wi-Fi chip of the electronic device 100 may stop working when the beidou short message chip sends or receives a signal. The Wi-Fi chip of the electronic device 100 may operate at a default transmit power (e.g., 16 dBm) when the beidou short message chip is not transceiving a signal.

In some possible embodiments, the Wi-Fi chip of the electronic device 100 may stop receiving signals during the transmission (Tx) of the beidou short message chip. The Wi-Fi chip can stop sending signals during the period that the Beidou short message chip receives (Rx) signals.

Optionally, the Wi-Fi chip of the electronic device 100 may stop sending the signal during the period when the beidou short message chip receives the signal. And when the Beidou short message chip does not receive signals, the Beidou short message chip works at the default transmitting power.

In some possible application scenarios, the beidou short message chip may send information that the beidou short message chip starts to receive signals, for example, a beidou Rx reception start notification (also referred to as a beidou Rx start notification), to the Wi-Fi chip when the beidou short message chip starts to receive signals. And when the Wi-Fi chip receives the Beidou Rx start notice, the Wi-Fi signal can be suspended from being sent. The big dipper short message chip can send the information that the big dipper short message chip finishes receiving the signal to the Wi-Fi chip when finishing receiving the signal, for example, a big dipper Rx reception finish notification (also called big dipper Rx finish notification). And when the Wi-Fi chip receives the Beidou Rx end notification, the Wi-Fi signal can be sent.

Further, the big dipper short message chip may send information that the big dipper short message chip starts sending a signal to the Wi-Fi chip when starting sending a signal, for example, a big dipper Tx sending start notification (also called big dipper Tx start notification, big dipper sending start communication Hi). And when the Wi-Fi chip receives the Beidou Tx starting notice, the Wi-Fi chip can suspend receiving of Wi-Fi signals. The big dipper short message chip can send the information that the big dipper short message chip finishes sending the signal, for example, big dipper Tx sends an end notice (also called big dipper Tx end notice, big dipper send end notice) to the Wi-Fi chip when finishing sending the signal. And when the Wi-Fi chip receives the Beidou Tx end notice, the Wi-Fi chip can start to receive Wi-Fi signals.

Illustratively, as shown in fig. 8. Fig. 8 illustrates a method for suspending operation of a Wi-Fi chip according to an embodiment of the present application.

When the Beidou short message chip receives signals, a Beidou Rx start notice can be sent to the Wi-Fi chip to inform the Wi-Fi chip that the Beidou short message chip is receiving the signals. And the Wi-Fi chip stops sending signals during the time window of the Beidou short message chip for receiving the signals until the Beidou short message chip finishes receiving the signals. After the big dipper short message chip receives the signal, a big dipper Rx completion notice can be sent to the Wi-Fi chip to inform the big dipper short message chip of completing the service of receiving the signal. And after the Wi-Fi chip receives the Beidou Rx completion notice, the Wi-Fi chip starts to send signals. This operation of the Wi-Fi chip being forced idle during the beidou short message chip receiving signal may be referred to as transmit pause (TxBlank).

When the big dipper short message chip is sending signals, can send big dipper Tx to the Wi-Fi chip and send the beginning notice, tell it that big dipper short message chip is sending signals. And the Wi-Fi chip stops receiving signals during the time window when the Beidou short message chip sends the signals until the Beidou short message chip sends the signals. After the big dipper short message chip sends the signal, a big dipper Tx end notice can be sent to the Wi-Fi chip to inform the big dipper short message chip of the completion of the service of sending the signal. And after the Wi-Fi chip receives the Beidou Tx end notification, the Wi-Fi chip starts to receive signals. This operation of the Wi-Fi chip being forced to idle during the period of the beidou short message chip sending a signal may be referred to as receive suspend (RxSuspend).

When the Beidou short message chip sends a signal, the sending operation of the Wi-Fi chip is not influenced. When the Beidou short message chip receives signals, the receiving operation of the Wi-Fi chip is not influenced.

Optionally, the beidou short message chip may send a first pause avoidance notification (e.g., a beidou Tx start notification) to the Wi-Fi chip through the application processor.

Therefore, the Wi-Fi chip can pause signal receiving during the Beidou short message sending period, pause signal sending during the Beidou short message chip signal receiving period, work at normal power in the Beidou short message receiving or data sending interval, and guarantee normal operation of the Beidou short message service and the Wi-Fi service under the condition that the power of the Wi-Fi is not greatly reduced and the performance of the Beidou short message service is not lost.

In a possible implementation manner, when the Wi-Fi chip and the beidou short message chip of the electronic device 100 are in a working state, the electronic device 100 may determine whether the Wi-Fi service may interfere with the beidou short message service through the beidou short message chip. The Wi-Fi chip can send working frequency band information (the frequency band information comprises a frequency point and a bandwidth) to the Beidou short message chip. The Beidou short message chip can judge whether the Wi-Fi service interferes with the Beidou short message service or not based on the received frequency band information. When the Beidou short message chip judges that the Wi-Fi service can interfere with the Beidou short message service, a first pause avoidance notification can be sent to the Wi-Fi chip when the signal is received and sent. The first pause avoidance notification comprises a big dipper Tx starting notification, a big dipper Tx ending notification, a big dipper Rx starting notification and a big dipper Rx ending notification. The Wi-Fi chip can execute corresponding avoidance operation based on the received first pause avoidance notification.

The Beidou short message chip judges whether the Wi-Fi service can interfere with the Beidou short message service or not based on the received frequency band information, whether the working frequency of the Wi-Fi chip of the received frequency band information is within the frequency range of a preset interference channel or not can be detected, if the working frequency of the Wi-Fi chip is judged to be within the frequency range of the preset interference channel based on the received frequency band information, the Beidou short message chip judges that the Wi-Fi service can interfere with the Beidou short message service, and a first pause avoidance notification is sent to the Wi-Fi chip. And if the Beidou short message chip detects that the working frequency of the Wi-Fi chip is not in the frequency range of the preset interference channel, judging that the Wi-Fi service does not interfere with the Beidou short message service, and not sending a first pause avoidance notification.

In one possible implementation manner, after receiving the first pause avoidance notification, the Wi-Fi chip may execute a corresponding avoidance operation based on the received first pause avoidance notification. For example, the Wi-Fi chip may suspend receiving signals when receiving the beidou Tx start notification and continue receiving signals after receiving the beidou Tx end notification. And when receiving the beginning notification of the Beidou Rx, suspending sending signals, and when receiving the ending notification of the Beidou Rx, continuing sending signals.

In another possible implementation manner, after receiving the first avoidance suspending notification, the Wi-Fi chip may execute a corresponding avoidance operation based on the received first avoidance suspending notification and the channel of the Wi-Fi operation.

For example, when the Beidou short message chip judges that the Wi-Fi service interferes with the Beidou short message service by detecting whether the working frequency of the Wi-Fi chip of the received frequency band information is within the frequency range of a preset interference channel, a first pause avoidance notification is sent to the Wi-Fi chip. When the Wi-Fi chip detects that the Wi-Fi works in a preset adjacent channel (for example, a channel 11 to a channel 13 of Wi-Fi 2.4 GHz), the Wi-Fi chip can pause signal receiving when receiving a Beidou Tx starting notice and continue signal receiving after receiving a Beidou Tx ending notice. And the sending of the signals is suspended when the Beidou Rx starting notice is received, and the signals are continuously sent when the Beidou Rx ending notice is received. When the Wi-Fi chip detects that the Wi-Fi operates on a preset intermediate channel (e.g., channel 9 to channel 10 of Wi-Fi 2.4 GHz), the Wi-Fi chip may operate with a reduced transmit power (e.g., the transmit power of the Wi-Fi chip is reduced from the default transmit power of 16dBm to 10 dBm) when receiving the beidou Tx start notification or the beidou Rx start notification, and operate with the default transmit power (e.g., 16 dBm) when receiving the beidou Tx end notification or the beidou Rx end notification.

Wherein the preset interference channel, the preset adjacent channel and the preset intermediate channel may be stored in a memory of the electronic device 100. Therefore, the Wi-Fi chip can select a proper avoidance mode based on a working channel of the Wi-Fi chip, and the mutual influence of the Beidou short message service and the Wi-Fi service is reduced.

In some possible application scenarios, the electronic device 100 stores preset indication information. The preset indication information comprises information whether the service of the Beidou short message chip is interfered when the Wi-Fi chip works in different channels of a 2.4GHz frequency band. The preset indication information also comprises operation information executed when the Beidou short message chip sends or receives signals when the Wi-Fi chip works in different channels.

Firstly, after the Beidou short message chip receives frequency band information of the Wi-Fi chip, whether the service of the Wi-Fi chip interferes with the Beidou short message service is judged based on preset indication information and the received frequency band information. When the Beidou short message chip judges that the Wi-Fi service can interfere with the Beidou short message service based on the preset indication information and the frequency band information, a first pause avoidance notification can be sent to the Wi-Fi chip. The Wi-Fi chip can execute corresponding operations (such as pause receiving, pause sending, power reduction and the like) based on the first pause avoidance notification and the preset indication information after receiving the first pause avoidance notification sent by the Beidou short message chip. Wherein the preset indication information may be stored in a memory. For example, the preset indication information may refer to table 1 shown below.

Table 1: preset indication information table

As shown in table 1, when the Wi-Fi chip operates on a preset remote channel (for example, channel 1-channel 8) in the 2.4GHz band, the Wi-Fi service does not affect the beidou short message service, and the Wi-Fi chip may operate at a default power (for example, 16 dBm). When the Wi-Fi chip works in a preset middle channel (for example, a channel 9-a channel 10) of a 2.4GHz frequency band, the Wi-Fi service can affect the Beidou short message service, and the Wi-Fi chip can reduce the transmission power (for example, the power is reduced by 6 dB) when the Beidou short message chip receives signals. When the Wi-Fi chip works in a preset adjacent channel (for example, the channel 11-the channel 13) of a 2.4GHz frequency band, the Wi-Fi service can affect the Beidou short message service, and the Wi-Fi chip can pause signal transmission when the Beidou short message receives signals. The Wi-Fi chip can pause receiving signals when the Beidou short message sends signals.

Illustratively, the Beidou short message chip may send a first pause avoidance notification to the Wi-Fi chip when it is determined that the Wi-Fi chip may affect the Beidou short message service based on the frequency band information sent by the Wi-Fi chip and the preset indication information shown in table 1. The Wi-Fi chip can judge the executed operation based on the first pause avoidance notice, the preset indication information and the channel used by the Wi-Fi chip. For example, after the Wi-Fi chip receives the big dipper Tx start notification sent by the big dipper short message chip, the Wi-Fi chip may perform an operation of suspending receiving signals based on the big dipper Tx start notification, table 1, and the channel (e.g., channel 12) on which the Wi-Fi operates. For another example, after the Wi-Fi chip receives the beidou Tx start notification sent by the beidou short message chip, the Wi-Fi chip may operate at a default power (e.g., 16 dBm) based on the beidou Tx start notification, table 1, and the channel on which the Wi-Fi operates (e.g., channel 10). For another example, after the Wi-Fi chip receives the beidou Rx start notification sent by the beidou short message chip, the Wi-Fi chip may operate at a reduced power (e.g., reduced to 10 dBm) based on the beidou Rx start notification, table 1, and the channel (e.g., channel 10) on which the Wi-Fi operates. For example, after the Wi-Fi chip receives the beidou Rx start notification sent by the beidou short message chip, the Wi-Fi chip may perform the operation of suspending sending signals based on the beidou Rx start notification, table 1 and the channel (e.g., channel 12) on which the Wi-Fi works.

Optionally, the Beidou short message chip may send a first pause avoidance notification to the Wi-Fi chip only when receiving a signal when it is determined that the Wi-Fi service may interfere with the Beidou short message service based on the preset indication information and the frequency band information of the Wi-Fi chip. And when the signal is sent, not sending a first pause avoidance notice to the Wi-Fi chip. The preset indication information also does not include the operation which can be executed by the Wi-Fi chip when the Beidou short message chip sends a signal. Therefore, the influence on the Wi-Fi service can be further reduced while the Beidou short message service is not influenced.

In a possible implementation manner, the electronic device 100 may determine the priority of the beidou short message service and the priority of the Wi-Fi service when detecting that the beidou short message chip and the Wi-Fi chip both work and the Wi-Fi chip works on a preset interference channel. The electronic device 100 may control the chip of the traffic of lower priority to perform a back-off operation (e.g., suspend reception, suspend transmission, reduce power, etc.) while the chip of the traffic of higher priority transmits or receives a signal based on the result of the priority. Wherein the step of priority detection may be performed by the application processor.

In some possible embodiments, if the electronic device 100 detects that the Wi-Fi service has a higher priority than the beidou short message service, a Wi-Fi priority start notification may be sent to the Wi-Fi chip. After receiving the Wi-Fi priority start notification, the Wi-Fi chip can work at default power and send the Wi-Fi priority start notification to the Beidou short message chip. Thereafter, the Wi-Fi chip may send a second avoidance pause notification (e.g., a Wi-Fi chip Tx start notification, a Wi-Fi chip Tx end notification, a Wi-Fi chip Rx start notification, a Wi-Fi chip Rx end notification) to the big-dipper short message chip when sending or receiving a signal. And after the Beidou short message chip receives the Wi-Fi priority information sent by the Wi-Fi chip, when a second suspension avoidance notice sent by the Wi-Fi chip is received, executing corresponding avoidance operation. When the Wi-Fi service or the Beidou short message service is changed, the electronic device 100 sends a Wi-Fi priority end notification to the Wi-Fi chip. The Wi-Fi chip does not send a pause avoidance notification to the Beidou short message chip any longer and sends the Wi-Fi priority end notification to the Beidou short message chip. And after the Beidou short message chip receives the Wi-Fi priority end notification, ending the avoidance operation. The Wi-Fi priority start notification can be used for indicating the Beidou short message service to avoid the Wi-Fi service.

For example, after the electronic device 100 detects that the priority of the Wi-Fi service is higher than that of the beidou short message service, the beidou short message chip receives the notification that the Wi-Fi service starts preferentially. If the Beidou short message chip receives the start notice of the Rx of the Wi-Fi chip, the Beidou short message chip suspends sending signals until the Beidou short message chip receives the end notice of the Rx of the Wi-Fi chip. If the Beidou short message chip receives the start notice of the Tx of the Wi-Fi chip, the Beidou short message chip suspends receiving signals until the Beidou short message chip receives the end notice of the Tx of the Wi-Fi chip. And after the Beidou short message chip receives the Wi-Fi priority end notification, ending the avoidance operation.

Optionally, the electronic device 100 may send a Wi-Fi priority start notification and a Wi-Fi priority end notification to the Wi-Fi chip and the beidou short message chip at the same time.

If the electronic device 100 detects that the priority of the Wi-Fi service is lower than that of the Beidou short message service, a Beidou priority start notification can be sent to the Wi-Fi chip. And after receiving the Beidou priority start notification, the Wi-Fi chip sends the Beidou priority start notification to the Beidou short message chip. The big dipper short message chip and the Wi-Fi chip can execute the one or more avoidance operations after receiving the big dipper priority start information, for example, the Wi-Fi chip sends frequency band information to the big dipper short message chip, the big dipper short message chip judges whether the Wi-Fi service interferes with the big dipper short message service based on the frequency band information, and sends a first pause avoidance notification to the Wi-Fi chip when judging that the Wi-Fi service can interfere with the big dipper short message service, and the Wi-Fi chip executes corresponding avoidance operations based on the first pause avoidance notification and a working channel. When the big dipper short message service or the Wi-Fi service is changed, the electronic device 100 sends a big dipper priority end notification to the Wi-Fi chip. And the Wi-Fi chip sends a Beidou priority completion notice to the Beidou short message chip. After receiving the Beidou priority completion notification, the Beidou short message chip does not send a pause avoidance notification to the Wi-Fi chip. Optionally, the electronic device 100 may send a Beidou first start notification and a Beidou first end notification to the Wi-Fi chip and the Beidou short message chip at the same time.

In other possible embodiments, the electronic device 100 may be preset as a default beidou short message service priority. When the electronic device 100 detects that the Wi-Fi chip and the Beidou short message chip work simultaneously and the Wi-Fi chip works in the preset interference channel, the Wi-Fi chip of the electronic device 100 avoids the Beidou short message chip. When the electronic device 100 judges that the Wi-Fi service priority is higher than the Beidou short message service, a Wi-Fi priority start notification and a Wi-Fi priority end notification are sent to the Wi-Fi chip and the Beidou short message chip, and the Beidou short message chip avoids the Wi-Fi chip during the Wi-Fi service priority period. For example, during the Wi-Fi service priority period, the Wi-Fi chip may send a second pause avoidance notification to the big dipper short message chip, the big dipper short message chip pauses to receive the big dipper signal when the Wi-Fi chip sends a signal based on the second pause avoidance notification, and pauses to send the big dipper signal when the Wi-Fi chip receives the signal.

When the electronic device 100 determines that the beidou short message service is preferred, the electronic device 100 may not send the beidou preference start notification, that is, when the electronic device 100 detects that the Wi-Fi chip and the beidou short message chip are simultaneously working, the Wi-Fi service avoids the beidou short message service. For example, the Wi-Fi chip can pause receiving Wi-Fi signals when the Beidou short message chip sends signals, and pause sending Wi-Fi signals when the Beidou short message chip receives signals. Optionally, the step of determining the priority may be completed by the application processor, the application processor sends a Wi-Fi priority start notification or a Wi-Fi priority end notification to the Wi-Fi chip, and the Wi-Fi chip sends a Wi-Fi priority start notification or a Wi-Fi priority end notification to the beidou short message chip. Or the application processor sends the Wi-Fi priority start notification or the Wi-Fi priority end notification to the Wi-Fi chip and the Beidou short message chip simultaneously.

Therefore, the Wi-Fi service priority is higher than the Beidou short message service priority, so that the Beidou short message service priority in the electronic equipment 100 is preset, the operation that the Wi-Fi chip avoids the Beidou short message chip can be executed before the electronic equipment 100 judges that the Beidou short message service priority is higher than the result of the Wi-Fi service, and the Beidou short message service is further prevented from being influenced by the Wi-Fi service.

The electronic device 100 may pre-store the priorities of the Beidou short message service and the Wi-Fi service, and then determine whether the Beidou short message service has a higher priority or the Wi-Fi service has a higher priority according to the preset priority.

For example, the electronic device 100 may preset the highest priority of the emergency rescue service in the beidou short message service and the second priority of the connection intelligent device service in the Wi-Fi service. And the priority of other Beidou short message services or Wi-Fi services is reduced in sequence. The electronic apparatus 100 may store the preset priorities of the respective services in the memory. When the electronic device 100 detects that the Wi-Fi chip and the Beidou short message chip work simultaneously, the electronic device 100 detects that the service executed by the Beidou short message chip is an emergency rescue service, and the service executed by the Wi-Fi chip is a connection intelligent device service. And obtaining that the Beidou short message service priority is higher than the Wi-Fi service based on the preset priority.

In some possible embodiments, the electronic device 100 may preset a score for both the beidou short message service and the Wi-F service, and then determine the priority level according to the score. Wherein the higher the score the higher the traffic priority. Optionally, when the score of the service of the big dipper short message chip is the same as the score of the service of the Wi-Fi chip, it is determined that the priority of the service executed by the big dipper short message chip is higher. Wherein the score may be stored in a memory of the electronic device 100. Wherein, the corresponding relation between the service and the score can be represented in the form of a configuration file.

Illustratively, table 2 shows corresponding scores for different beidou short message services and Wi-Fi services. The electronic device 100 may obtain, through the lookup table 2, a plurality of services of the beidou short message chip and a score corresponding to each service, and also a plurality of services of the Wi-Fi chip and a score corresponding to each service.

The service of the big dipper short message chip may include: flight mode, idle (idle) state, search (searching) state, short message communication, location reporting, emergency rescue message, and the like. The score of the flight mode may be 1, the score of the idle state may be 80, the score reported by the location may be 80, and the like.

The service of the Wi-Fi chip can comprise the following steps: an airplane mode, a standby state, wi-Fi scanning, location Based Services (LBS) assisted positioning, wi-Fi talking, signal networking, wi-Fi hotspot mode, and the like. Where the standby state may score 60, the wi-Fi hotspot pattern may score 68, the smart device connected may score 85, and so on.

TABLE 2

Big dipper short message service	Score of	Wi-Fi services	Score of
				Flight mode	1	Flight mode	0
Idle State (Idle)	80	Standby	60
				Searching state (Searching)	70	Wi-Fi scanning	71
Short message communication	100	LBS assisted positioning	72
				Location reporting	80	Vowi-Fi call	73
Emergency rescue message	100	Data networking	74
						Wi-Fi hotspot	68
		Wireless screen	75
						P2P file sharing	69
		Connecting intelligent equipment	85

When the electronic device 100 detects that the Wi-Fi chip and the Beidou short message chip work simultaneously, if the electronic device 100 detects that the service executed by the Beidou short message chip is an emergency rescue service, the service executed by the Wi-Fi chip is a connection intelligent device service. And obtaining the score of the Beidou short message service based on the preset service score, wherein the score is higher than the Wi-Fi service, and the Beidou short message service priority can be judged to be higher than the Wi-Fi service. If the electronic device 100 detects that the service executed by the Beidou short message chip is the position reporting service, the service executed by the Wi-Fi chip is the connection intelligent device service. And obtaining the score of the Beidou short message service lower than the Wi-Fi service based on the preset service score, namely judging that the priority of the Wi-Fi service is higher than that of the Beidou short message service.

In one possible implementation, the electronic device 100 is preset as default beidou short message service priority. The electronic device 100 may send a first avoidance notification to the Wi-Fi chip when detecting that the Wi-Fi chip and the beidou short message chip are working simultaneously. The first avoidance notification can be used for triggering the Wi-Fi chip to detect whether the Wi-Fi chip works on a preset interference channel. For example, the electronic device 100 may determine whether the Wi-Fi chip operates in a preset interference channel through the beidou short message chip. The Wi-Fi chip can send frequency band information to the Beidou short message chip after receiving the first avoidance notification, the Beidou short message chip can judge whether the Wi-Fi chip works on a preset interference channel or not through the frequency band information, and if the Beidou short message chip judges that the Wi-Fi chip works on the preset interference channel. And the Wi-Fi chip and the Beidou short message chip execute the operation of the avoidance scheme (1).

Optionally, if the electronic device 100 presets that the Beidou short message service is default to be preferred, it is determined that the Wi-Fi service is preferred. The electronic device 100 may transmit the Wi-Fi priority start notification after transmitting the first avoidance notification, or the electronic device 100 may transmit only the Wi-Fi priority start notification without transmitting the first avoidance notification.

In another possible implementation manner, the electronic device 100 is preset to default to the beidou short message service priority. The Wi-Fi chip of the electronic device 100 may send the changed frequency band information to the beidou short message chip when the working frequency is changed. When the Beidou short message chip is in a working state, whether the Wi-Fi service interferes with the Beidou short message service or not can be judged based on the frequency band information which is sent by the Wi-Fi chip and is closest in time. And when the Beidou short message service judges that the Wi-Fi service can interfere with the Beidou short message service, sending a first pause avoidance notification to the Wi-Fi chip. After the Wi-Fi chip receives the first pause avoidance notification, the Wi-Fi chip can execute corresponding operation based on the first pause avoidance notification and the preset indication information.

The implementation methods of the multiple avoidance schemes provided by the above embodiments may be used in combination with each other, and are not limited herein.

Next, a flow chart of a communication method provided in an embodiment of the present application is described with reference to fig. 9. The electronic device 100 may include, among other things, the chip system 700 shown in fig. 7. The electronic device 100 is preset to be the default Beidou short message service priority.

S901, the electronic device 100 detects that the Wi-Fi chip 703 and the Beidou short message chip 702 work simultaneously.

The electronic device 100 can detect that the Wi-Fi chip 703 and the beidou short message chip 702 work simultaneously by the following method. For example, after the electronic device 100 receives the input that the user turns on the Wi-Fi function and the beidou short message function, it is determined that the Wi-Fi chip 703 and the beidou short message chip 702 are simultaneously working before the input that the user turns off the Wi-Fi function or the beidou short message function is received. The step of determining that the Wi-Fi chip 703 and the beidou short message chip 702 work simultaneously may be executed by the application processor 701.

S902, the electronic device 100 acquires the service information of the Wi-Fi chip 703 and the Beidou short message chip 702.

The electronic device 100 may obtain information of services being executed by the Wi-Fi chip 703 and the beidou short message chip 702, such as the category of the service, the name of the service, and the like. The electronic device 100 may obtain services being executed by the beidou short message chip 702 and the Wi-Fi chip 703 through an interface (e.g., a PCIE interface, an SDIO interface). Further, the application processor 701 may execute step S902 again when detecting that the beidou short message service or the Wi-Fi service changes.

S903, does the electronic device 100 determine whether the priority of the beidou short message service is higher than that of the Wi-Fi service?

The application processor 701 of the electronic device 100 may determine, based on the pre-stored priority information (e.g., the service score table shown in table 2) of the beidou short message service and the Wi-Fi service, whether the priority of the ongoing service of the beidou short message chip 702 is higher or the priority of the ongoing service of the Wi-Fi chip 703 is higher.

When the electronic device 100 determines that the priority of the beidou short message service is lower than the priority of the Wi-Fi service, the electronic device 100 may execute step S904.

When the electronic device 100 determines that the priority of the beidou short message service is higher than the priority of the Wi-Fi service, the electronic device 100 may execute step S905.

S904, the Beidou short message chip 702 avoids the Wi-Fi chip 703.

After the application processor 701 of the electronic device 100 determines that the priority of the beidou short message service is lower than the priority of the Wi-Fi service, the application processor 701 may send a Wi-Fi priority start notification to the Wi-Fi chip 703. After receiving the Wi-Fi priority start notification, the Wi-Fi chip 703 may send the Wi-Fi priority start notification to the beidou short message chip 702. Then, when the Wi-Fi chip 703 starts to send a signal, the Beidou short message chip 702 sends a Wi-Fi chip Tx start notification to the Beidou short message chip 702, and the Beidou short message chip 702 suspends receiving the Beidou signal after receiving the Wi-Fi chip Tx start notification. When the Wi-Fi chip 703 finishes sending the signal, the Beidou short message chip 702 sends a Wi-Fi chip Tx finish notification, and after receiving the Wi-Fi chip Tx finish notification, the Beidou short message chip 702 continues to receive the Beidou signal. When the Wi-Fi chip 703 starts receiving signals, the Wi-Fi chip Rx start notification is sent to the Beidou short message chip 702, and after the Beidou short message chip 702 receives the Wi-Fi chip Rx start notification, the Beidou signals are suspended from being sent. When the Wi-Fi chip 703 finishes receiving the signal, the Wi-Fi chip Rx finish notification is sent to the Beidou short message chip 702, and after the Beidou short message chip 702 receives the Wi-Fi chip Rx finish notification, the Beidou signal continues to be sent. Further, when the Wi-Fi chip 703 detects that the Wi-Fi chip 703 operates on a preset interference channel, a second suspended avoidance notification is sent to the north-fighting short message chip 702.

When the application processor 701 of the electronic device 100 detects that the Wi-Fi service or the beidou short message service changes, a Wi-Fi priority end notification is sent to the Wi-Fi chip 703. After receiving the Wi-Fi priority end notification, the Wi-Fi chip 703 sends the Wi-Fi priority end notification to the beidou short message chip 702. The Wi-Fi chip 703 avoids the beidou short message chip 702, and the electronic device 100 executes step S901.

Before the Wi-Fi chip 703 receives the Wi-Fi priority start notification, the default Beidou short message service is priority. The Wi-Fi chip 703 avoids the beidou short message chip 702, and the detailed steps are as shown in step S905.

Optionally, the application processor 701 of the electronic device 100 may send a Wi-Fi priority start notification to the Wi-Fi chip 703 and the beidou short message chip 702 simultaneously when determining that the Wi-Fi service priority is higher than the beidou short message service. The application processor 701 may also send a Wi-Fi priority end notification to the Wi-Fi chip 703 and the beidou short message chip 702 simultaneously when detecting that the Wi-Fi service or the beidou short message service has changed.

S905, the Wi-Fi chip 703 avoids the Beidou short message chip 702.

When the application processor 701 of the electronic device 100 determines that the priority of the beidou short message service is higher than that of the Wi-Fi service. The Wi-Fi chip 703 sends the frequency band information of Wi-Fi operation to the Beidou short message chip 702. After receiving the frequency band information, the beidou short message chip 702 determines whether the Wi-Fi service interferes with the beidou short message service based on the frequency band information and preset indication information (for example, the preset indication information table shown in table 1) stored in the memory of the electronic device 100. When the big dipper short message chip 702 determines that the Wi-Fi service may interfere with the big dipper short message service, the big dipper short message chip 702 may send a first avoidance suspension notification (e.g., a big dipper Tx start notification, a big dipper Tx end notification, a big dipper Rx start notification, and a big dipper Rx end notification) to the Wi-Fi chip 703 when sending or receiving a signal. After receiving the first pause avoidance notification, the Wi-Fi chip 703 may execute corresponding operations (e.g., pause reception, pause transmission, and reduce power) during the period when the beidou short message chip 702 transmits or receives a signal based on the preset indication information and the first pause avoidance notification. Since the electronic device 100 defaults that the beidou short message service is preferred, the application processor 701 may not send the notification related to the priority.

When the beidou short message service or the Wi-Fi service is changed, the electronic device 100 may execute step S901.

In some possible application scenarios, in the processes of step S901 to step S905 described above. If the electronic device 100 receives an input that the user turns off the beidou short message function or turns off the Wi-Fi function, the electronic device 100 stops executing the avoidance scheme. For example, the application processor of the electronic device 100 may send a notification to the beidou short message chip and the Wi-Fi chip to end the avoidance. And stopping executing the avoidance scheme after the Beidou short message chip and the Wi-Fi chip receive the notification.

Thus, since the overhead of the beidou short message service is relatively large, the time for the electronic device 100 to execute the beidou short message service is generally short. The Wi-Fi signals are temporarily stopped from being received during the period that the Beidou short message chip sends the signals, and the Wi-Fi signals are temporarily stopped from being sent during the period that the Beidou short message chip receives the signals. The Wi-Fi service can not influence the Beidou short message service, and meanwhile, the Wi-Fi service can not greatly reduce the transmitting power to avoid the Beidou short message service in the starting period of the Beidou short message function, so that the Wi-Fi service can be finished under smaller influence.

The steps shown in fig. 9 combine some of the embodiments provided above. The implementation method described in fig. 9 is only an example, and does not specifically limit the present application. The application can reasonably combine the multiple implementation modes provided by the method, and under the condition that the Wi-Fi transmitting power is not required to be greatly reduced, the influence of the Wi-Fi chip on the Beidou short message chip is reduced, and the Wi-Fi chip can transmit and receive signals with default power in the idle time of the Beidou short message chip is ensured.

A back-off scheme for switching the frequency range of operation of a communication connection used by Wi-Fi services of electronic device 100 is next described in conjunction with fig. 10.

In a possible implementation manner, when both the beidou short message chip and the Wi-Fi chip of the electronic device 100 operate, and if the electronic device 100 detects that the operating frequency of the Wi-Fi is within the frequency range of the preset interference channel, the electronic device 100 may switch the frequency band of the communication connection for receiving and sending the Wi-Fi service, and continue to send or receive the service for receiving and sending the signal through the Wi-Fi connection before through the communication connection in the other frequency range (i.e., the frequency range except the frequency range of the preset interference channel in the 2.4GHz frequency band).

In some possible embodiments, the electronic device 100 may disconnect the Wi-Fi connection in the preset interference channel frequency range, establish a Wi-Fi connection in the 5GHz frequency range, and perform transmission or reception of a signal of a Wi-Fi service through the Wi-Fi connection in the 5GHz frequency range.

For example, electronic device 100 may disconnect a Wi-Fi connection in the 2.4GHz band with the AP device via the Deauth frame. Thereafter, the electronic device 100 may establish a Wi-Fi connection of a 5GHz band with the AP device through the (Re) Association frame. When the electronic device 100 and the AP device establish a Wi-Fi connection in a 5GHz band, the electronic device may negotiate with the AP device through a (Re) Association frame or an action frame to operate in a MIMO mode or a SISO mode in the 5GHz band.

In some possible embodiments, the electronic device 100 may disconnect the Wi-Fi connection within the preset interference channel frequency range, the electronic device 100 may establish a cellular communication connection, and perform transmission or reception of signals of Wi-Fi traffic through the cellular communication connection.

In some possible embodiments, electronic device 100 may disconnect Wi-Fi connections within a preset interference channel range and re-establish Wi-Fi connections on channels other than the preset interference channel (e.g., channel 1-channel 8) within the 2.4GHz band (i.e., wi-Fi connections on non-preset interference channels of the 2.4GHz band).

In some possible application scenarios, the Wi-Fi chip of the electronic device 100 operates on a preset interference channel in a 2.4GHz band, and the executed service is a Wi-Fi hotspot mode service (i.e., the electronic device 100 serves as an access point device to establish Wi-Fi connection with other electronic devices). The electronic device 100 may disconnect the Wi-Fi connection on the preset interference channel in the 2.4GHz band, and reestablish the Wi-Fi connection on the channels other than the preset interference channel in the 2.4GHz band.

In the embodiments provided in the present application, the avoidance schemes may be combined with each other, and are not limited herein.

For example, when the electronic device 100 executes step S905 shown in fig. 9, before the Wi-Fi chip of the electronic device 100 sends the frequency band information to the foup short message chip, it may detect whether the frequency band where the Wi-Fi connection is located is within a preset interference channel frequency range of a 2.4GHz frequency band. If the Wi-Fi chip judges that the Wi-Fi chip is in the frequency range of the preset interference channel, the Wi-Fi chip can disconnect Wi-Fi connection in the frequency range, reestablish Wi-Fi connection on the 5GHz frequency band, and transmit data of Wi-Fi service through the Wi-Fi connection on the 5GHz frequency band. Or reestablish the cellular communication connection and transmit data of the Wi-Fi traffic over the cellular communication connection. Or reestablishing the Wi-Fi connection on the non-preset interference channel of the 2.4GHz frequency band, and transmitting the data of the Wi-Fi service through the connection.

If the electronic device 100 has already established a Wi-Fi connection in the 5GHz band and is transmitting data of a certain service through the Wi-Fi connection in the 5GHz band, the electronic device 100 may only reestablish the cellular communication connection or reestablish the Wi-Fi connection on the non-preset interference channel in the 2.4GHz band. If the cellular network signal is poor in the current environment of the electronic device 100, the electronic device 100 may only re-establish the Wi-Fi connection on the non-preset interference channel in the 2.4GHz band. If the electronic device 100 cannot disconnect the Wi-Fi connection on the preset interference channel, the electronic device 100 may continue to perform the operation shown in the step S905.

In this way, the electronic device 100 may first try to switch the frequency range of the communication connection of the Wi-Fi service, so that the frequency ranges of the Wi-Fi service and the beidou short message service are not crossed, and the performance of the Wi-Fi service and the beidou short message service may be ensured to the maximum extent. When the frequency range of the Wi-Fi service cannot be switched, the electronic device 100 may avoid the beidou short message service by using the Wi-Fi service through the above-mentioned pause mode, so as to reduce the mutual influence between the Wi-Fi service and the beidou short message service.

In some possible embodiments, when the electronic device 100 reestablishes the Wi-Fi connection on the non-preset interference channel in the 2.4GHz band, the Wi-Fi chip of the electronic device 100 may also suspend receiving the signal when the beidou short message chip sends the signal, and suspend sending the signal when the beidou short message chip receives the signal. And/or the Wi-Fi chip of the electronic device 100 may use an antenna that is the farthest european distance from the antenna of the beidou short message chip. And/or electronic device 100 may reduce the transmit power of the Wi-Fi chip (e.g., by 2 dB).

In some possible embodiments, the electronic device 100 may prioritize the frequency bands of the re-established communication connection. After the electronic device 100 disconnects Wi-Fi connection on the preset interference channel in the 2.4GHz band, communication connection may be reestablished according to the priority. For example, the electronic device 100 may be set with a higher priority for Wi-Fi connections in the 5GHz band than for Wi-Fi connections on a non-preset interference channel in the 2.4GHz band. The Wi-Fi connection on the non-preset interference channel of the 2.4GHz band has a higher priority than the cellular communication connection. Then, after the electronic device 100 disconnects the Wi-Fi connection on the preset interference channel in the 2.4GHz band, it first tries to establish a Wi-Fi connection in the 5GHz band. And if the Wi-Fi connection of the 5GHz frequency band cannot be established, trying to establish the Wi-Fi connection on a non-preset interference channel of the 2.4GHz frequency band, and so on.

Therefore, the Wi-Fi connection on the preset interference channel is disconnected, and communication connections in other frequency ranges are established to transmit signals of Wi-Fi services. The method can ensure the normal operation of the Wi-Fi service and can not interfere the execution of the Beidou short message service.

In some possible embodiments, the electronic device 100 detects that the Wi-Fi chip and the beidou short message chip work simultaneously, and if the Wi-Fi chip of the electronic device 100 works in a Dual Band Adaptive Concurrent (DBAC) mode, that is, the electronic device 100 establishes a Wi-Fi connection in a 2.4GHz band and a Wi-Fi connection in a 5GHz band at the same time, the Wi-Fi chip may send or receive signals in the two bands. Electronic device 100 may disconnect Wi-Fi connectivity in the 2.4GHz band. In this way, electronic device 100 may continue to receive and transmit signals of Wi-Fi traffic via a Wi-Fi connection in the 5GHz band. And the performance of the Wi-Fi service is ensured under the condition that the Beidou short message service is not influenced.

Optionally, the electronic device 100 may establish the cellular communication connection while disconnecting the Wi-Fi connection on the preset interference channel. Or, the electronic device 100 may use the antenna with the farthest euclidean distance from the antenna used by the beidou short message chip to transmit the signal of the Wi-Fi connection in the 2.4GHz band. Alternatively, electronic device 100 may reduce the transmit power of a Wi-Fi connection in the 2.4GHz band. Alternatively, electronic device 100 may establish a Wi-Fi connection on a non-pre-set interference channel in the 2.4GHz band.

Fig. 10 shows a flowchart of a communication method provided in an embodiment of the present application. The electronic device 100 may include, among other things, a chip system 700 as shown in FIG. 7.

S1101, the electronic device 100 detects that the Wi-Fi chip 703 and the Beidou short message chip 702 work simultaneously.

For specific description of step S1101, reference may be made to the embodiment described in step S901 of fig. 9, which is not described herein again.

S1102, the electronic device 100 determines whether the Wi-Fi operates in a preset interference channel of a 2.4GHz frequency band.

When the electronic device 100 determines that the Wi-Fi chip 703 and the beidou short message chip 702 work simultaneously, the electronic device 100 may determine whether the Wi-Fi service will interfere with the beidou short message service based on whether the working frequency range of the Wi-Fi chip 703 is within the preset interference channel range of the 2.4GHz band. If the electronic device 100 determines that the Wi-Fi chip 703 operates outside the preset interference channel range, the electronic device 100 determines that the Wi-Fi service does not affect the beidou short message service, and the electronic device 100 executes step S1103. If the electronic device 100 determines that the Wi-Fi chip 703 operates within the preset interference channel range of the 2.4GHz band, the electronic device 100 determines that the Wi-Fi service may affect the beidou short message service, and the electronic device 100 executes step S1104. The operation of the electronic device 100 for judging whether the Wi-Fi chip works in the preset interference channel can be realized by the application processor 701, the Wi-Fi chip 703 or the beidou short message chip 702.

S1103, the Wi-Fi chip 703 of the electronic device 100 operates with default power.

The electronic device 100 determines that the working frequency range of the Wi-Fi chip 703 is outside the frequency range of the preset interference channel, the Wi-Fi service does not interfere with the beidou short message service, and the Wi-Fi chip works with default power. And after the service execution on the Wi-Fi chip is finished, returning to the step S1102.

S1104, the communication connection used by the Wi-Fi service is switched by the electronic equipment 100.

The electronic device 100 determines that the working frequency range of the Wi-Fi chip 703 is within the frequency range of the preset interference channel, and the Wi-Fi service interferes with the beidou short message service, so that the electronic device 100 can disconnect the Wi-Fi connection on the preset interference channel, reestablish the Wi-Fi connection on the 5GHz frequency band, and transmit data of the Wi-Fi service through the Wi-Fi connection on the 5GHz frequency band. Or reestablishing the cellular communication connection and transmitting the data of the Wi-Fi service through the cellular communication connection, or reestablishing the Wi-Fi connection on the non-preset interference channel of the 2.4GHz frequency band and transmitting the data of the Wi-Fi service through the connection.

Therefore, the electronic device 100 can reduce the influence of the Wi-Fi service on the Beidou short message service while not influencing the receiving and sending of the Wi-Fi service signal.

A back-off scheme for reducing the transmit power of a Wi-Fi chip is next described in conjunction with fig. 11.

In a possible implementation manner, when both the beidou short message chip and the Wi-Fi chip of the electronic device 100 are in operation, if the electronic device 100 detects that the operating frequency band of Wi-Fi is the 2.4GHz band of Wi-Fi, or if the electronic device 100 detects that the operating frequency band of Wi-Fi is within the frequency range of a preset adjacent channel (for example, channel 11-channel 13) of the 2.4GHz band of Wi-Fi, the electronic device 100 may reduce the transmission power of the Wi-Fi chip. Therefore, the influence of Wi-Fi service on Beidou short message service can be reduced.

In some possible application scenarios, if the electronic device 100 operates in the 2.4GHz band and the transmission power of the Wi-Fi chip is higher than a preset power threshold (e.g., 15 dBm), the electronic device 100 may set the transmission power to a preset operating power (e.g., 10 dBm).

For example, the beidou short message chip and the Wi-Fi chip of the electronic device 100 operate simultaneously, where the transmission power of the Wi-Fi chip of the electronic device 100 is 16dBm, and the electronic device 100 detects that the value is greater than a preset power threshold, and adjusts the value of the transmission power of the Wi-Fi chip to a preset operating power (e.g., 10 dBm).

In some possible application scenarios, the Wi-Fi chip of the electronic device 100 may adjust the transmission power to a preset operating power (e.g., 10 dBm) when the beidou short message chip receives a signal, and operate with a default transmission power at other times. Therefore, the interference of the Wi-Fi service to the Beidou short message service can be reduced, and meanwhile, the influence of the Beidou short message service on the Wi-Fi service is reduced.

Fig. 11 is a flowchart illustrating a communication method according to an embodiment of the present application. The electronic device 100 may include, among other things, a chip system 700 as shown in FIG. 7.

S1201, the electronic device 100 detects that the Wi-Fi chip 703 and the Beidou short message chip 702 work simultaneously.

For a specific description of step S1201, reference may be made to the embodiment described in step S901 of fig. 9, which is not described herein again.

S1202, the electronic device 100 determines whether the Wi-Fi operates in a preset interference channel of a 2.4GHz frequency band.

The step of determining whether the Wi-Fi operates in the preset interference channel in the 2.4GHz band by the electronic device 100 may refer to the embodiment shown in step S1102 of fig. 11, which is not described herein again. If the electronic device 100 determines that the Wi-Fi chip 703 operates outside the preset interference channel frequency range of the 2.4GHz band, the electronic device 100 executes step S1203. If the electronic device 100 determines that the Wi-Fi chip 703 operates within the preset interference channel range of the 2.4GHz band, the electronic device 100 executes step S1204.

S1203, the Wi-Fi chip 703 of the electronic device 100 operates with default power.

The electronic device 100 determines that the working frequency range of the Wi-Fi chip 703 is outside the frequency range of the preset interference channel, the Wi-Fi service does not interfere with the beidou short message service, and the Wi-Fi chip 703 works with default power. And after the service execution on the Wi-Fi chip 703 is completed, returning to step S1202.

S1204, the electronic device 100 reduces the transmission power of the Wi-Fi chip 703.

The electronic device 100 determines that the working frequency range of the Wi-Fi chip 703 is within the frequency range of the preset interference channel, the Wi-Fi service interferes with the beidou short message service, and the Wi-Fi chip 703 is reduced from the default transmission power to the preset working power (e.g., 10 dBm).

Therefore, the influence of the Wi-Fi service on the Beidou short message service is reduced.

The avoidance scheme for switching the antenna used by the Wi-Fi chip provided by the embodiment of the present application is described next with reference to fig. 12 to 13.

In a possible implementation manner, when both the beidou short message chip and the Wi-Fi chip of the electronic device 100 operate, if the electronic device 100 detects that the operating frequency band of Wi-Fi is the 2.4GHz band of Wi-Fi, or if the electronic device 100 detects that the operating frequency band of Wi-Fi is within the frequency range of a preset adjacent channel (for example, channel 11-channel 13) of the 2.4GHz band of Wi-Fi, the electronic device 100 may switch the antenna used by the Wi-Fi chip to the antenna farthest from the antenna used by the beidou short message chip in euclidean distance. The longer the distance between the antenna used by the Wi-Fi chip and the antenna used by the Beidou short message chip is, the higher the isolation between the antennas is. The higher the isolation between the antennas, the less interference is generated with each other. Therefore, the influence of Wi-Fi service on Beidou short message service can be reduced.

Optionally, when the electronic device 100 includes a Transmit Antenna Selection (TAS) antenna, the electronic device 100 may control the Wi-Fi chip to preferentially use the TAS antenna for communication when the beidou short message chip and the Wi-Fi chip operate simultaneously. The TAS antenna is a standby antenna and can be used when the performance of an antenna used in Wi-Fi service is poor. Thus, since the TAS antenna is a backup antenna, the electronic device 100 can reduce interference of the Wi-Fi signal to the beidou short message signal while not interfering with a service of transmitting and receiving signals through other antennas.

That is to say, the electronic device 100 includes a TAS antenna, and when the beidou short message chip and the Wi-Fi chip of the electronic device 100 are both in operation, and if the electronic device 100 detects that the working frequency band of Wi-Fi is within the frequency range of the preset interference channel (for example, channel 9-channel 13) of the 2.4GHz frequency band of Wi-Fi, the Wi-Fi chip of the electronic device 100 preferentially uses the TAS antenna. The electronic device 100 preferentially uses the antenna with the farther euclidean distance from the TAS antenna and the antenna used by the beidou short message chip. If the Wi-Fi chip of the electronic device 100 cannot use the TAS antenna, the electronic device 100 preferentially uses the antenna with the farther euclidean distance from the antenna used by the beidou short message chip among other antennas.

Fig. 12 is a schematic diagram illustrating an antenna structure of the electronic device 100.

Illustratively, as shown in fig. 12, the electronic device 100 may include at least three antennas including an antenna 1300 (Core 1300), an antenna 1301 (Core 1301), an antenna 1302 (Core 1302), an antenna 1303 (Core 1303), an antenna 1304 (Core 1304), an antenna 1305 (Core 1305), and an antenna 1306 (Core 1306). The antenna 1300 is an antenna for receiving Long Term Evolution (LTE) and performing frequency division multiplexing of 2.4GHz band for Wi-Fi and 5GHz band for Wi-Fi. The antenna 1300 may also be used to transmit a signal of the beidou short message. The antenna 1301 is an antenna for LTE diversity reception and time division multiplexing of the 2.4GHz band of Wi-Fi. The antenna 1302 and the antenna 1303 are both TAS antennas for Wi-Fi. The Wi-Fi chip of electronic device 100 may transmit signals from two or more antennas with better selected channel conditions. The antenna 1304 is an antenna for LTE reception and transmission. Antenna 1305 is an LTE receive antenna. The antenna 1306 is an antenna used in a MIMO mode of a 5GHz band of Wi-Fi.

When the big dipper short message chip and the Wi-Fi chip of the electronic device 100 are both in operation, the big dipper short message chip of the electronic device 100 receives and transmits signals through the antenna 1300. The Wi-Fi chip of the electronic device 100 performs reception or transmission of signals through the antenna 1301. If the electronic device 100 detects that the working frequency band of the Wi-Fi is the 2.4GHz band of the Wi-Fi, or if the electronic device 100 detects that the working frequency band of the Wi-Fi is within the frequency range of a preset adjacent channel (for example, channel 11-channel 13) of the 2.4GHz band of the Wi-Fi, the electronic device 100 may switch an antenna used by the Wi-Fi chip to be any one of the antennas 1303-antenna 1306. The electronic device 100 selects an antenna used by the Wi-Fi chip based on two factors, namely the euclidean distance between the antennas and the antenna 1301 and whether the antenna is a TAS antenna. The order of selecting the antennas by the electronic device 100 is antenna 1303, antenna 1302, antenna 1305, antenna 1304, antenna 1301, and antenna 1306. Wherein the TAS antenna has a higher priority than other non-TAS antennas. If the antennas that can be selected are both TAS antennas or both non-TAS antennas, the higher the value of the euclidean distance the higher the antenna priority.

When the big dipper short message chip and the Wi-Fi chip of the electronic device 100 are both in operation, the big dipper short message chip of the electronic device 100 receives and transmits signals through the antenna 1300. The Wi-Fi chip of the electronic device 100 operates in a Multiple Input Multiple Output (MIMO) mode, and in the MIMO mode, at least two antennas of the electronic device 100 receive or transmit signals of the Wi-Fi service. Here, the Wi-Fi chip of the electronic apparatus 100 may perform reception or transmission of signals through two or more antennas of the antennas 1301 to 1306. If the electronic device 100 detects that the working frequency band of the Wi-Fi is the 2.4GHz frequency band of the Wi-Fi, or if the electronic device 100 detects that the working frequency band of the Wi-Fi is within the frequency range of a preset adjacent channel (for example, channel 11-channel 13) of the 2.4GHz frequency band of the Wi-Fi, the electronic device 100 selects two or more antennas in the order of a TAS antenna whose euclidean distance from an antenna used in a beidou short message chip is large to small and a non-TAS antenna whose euclidean distance from the antenna used in the beidou short message is large to small, where the order of selecting the antennas by the Wi-Fi chip is the antenna 1303, the antenna 1302, the antenna 1305, the antenna 1304, the antenna 1301, and the antenna 1306. The number of the antennas used by the Wi-Fi chip at the beginning is the same as the number of the antennas used by the Wi-Fi chip after the antennas are switched. The Wi-Fi chip can receive and transmit Wi-Fi service signals through the more than two antennas, and mutual interference between the Wi-Fi service and the Beidou short message service is reduced.

For example, when the beidou short message chip and the Wi-Fi chip of the electronic device 100 are both in operation, the beidou short message chip of the electronic device 100 sends and receives signals through the antenna 1300, and the Wi-Fi chip of the electronic device 100 sends (receives) signals through the antenna 1301 and the antenna 1306, and when the electronic device 100 detects that the Wi-Fi chip operates within the frequency range of a preset interference channel (for example, channel 9-channel 13) in the 2.4GHz band of Wi-Fi, the Wi-Fi chip will receive (send) signals through the antenna 1303 and the antenna 1302.

In one possible implementation, electronic device 100 may reduce the transmit power of the Wi-Fi chip while switching the antenna used by the Wi-Fi chip.

Fig. 13 is a flowchart illustrating a communication method according to an embodiment of the present application. The electronic device 100 may include, among other things, a chip system 700 as shown in FIG. 7. The electronic device 100 may include multiple antennas as shown in fig. 12.

S1401, electronic equipment 100 detects that Wi-Fi chip 703 and big dipper short message chip 702 work simultaneously.

For specific description of step S1401, reference may be made to the embodiment described in step S901 of fig. 9, which is not described herein again.

S1402, the electronic device 100 determines whether the Wi-Fi operates in a preset interference channel of a 2.4GHz frequency band.

The step of determining whether the Wi-Fi operates in the preset interference channel in the 2.4GHz band by the electronic device 100 may refer to the embodiment shown in step S1102 of fig. 11, which is not described herein again. If the electronic device 100 determines that the Wi-Fi chip 703 operates outside the preset interference channel frequency range of the 2.4GHz band, the electronic device 100 executes step S1403. If the electronic device 100 determines that the Wi-Fi chip 703 operates within the preset interference channel range of the 2.4GHz band, the electronic device 100 executes step S1404.

S1403, the Wi-Fi chip 703 of the electronic device 100 defaults to power, and the antenna works by default.

The electronic device 100 determines that the working frequency range of the Wi-Fi chip 703 is outside the frequency range of the preset interference channel, the Wi-Fi service does not interfere with the beidou short message service, and the Wi-Fi chip works with a default power and a default antenna (e.g., the antenna 1302 shown in fig. 12). After the service execution of the Wi-Fi chip 703 is completed, the process returns to step S1402.

S1404, the electronic device 100 switches the antenna used by the Wi-Fi service.

The electronic device 100 determines that the working frequency range of the Wi-Fi chip 703 is within the frequency range of a preset interference channel, the Wi-Fi service interferes with the beidou short message service, and the Wi-Fi chip 703 is switched from the default antenna (for example, the antenna 1302) to the antenna used by the beidou short message chip (for example, the antenna 1301) based on the euclidean distance between the antenna and the antenna used by the beidou short message chip and whether the antenna used by the Wi-Fi chip 703 is the TAS antenna. For example, to antenna 1303.

As mentioned above, the above embodiments can be used in combination, and are not limited herein. For example, when the working mode of the Wi-Fi chip is switched from the MIMO mode in the 2.4GHz band to the SISO mode in the 2.4GHz band, the electronic device 100 may further reduce the influence of the Wi-Fi service on the beidou short message service by combining the above avoidance scheme for switching the transmitting antenna and/or the scheme for reducing the transmitting power of the Wi-Fi chip.

Next, a solution for reducing avoidance of an antenna used by a Wi-Fi chip according to an embodiment of the present application is described with reference to fig. 14.

In one possible implementation, the electronic device 100 detects that both the beidou short message chip and the Wi-Fi chip are operating, wherein the Wi-Fi chip sends or receives Wi-Fi signals using at least two antennas. When the electronic device 100 detects that the Wi-Fi chip operates on the preset interference channel, the electronic device 100 may reduce the number of antennas used by the Wi-Fi chip. The more the number of the antennas used by the Wi-Fi service is, the greater the interference on the Beidou short message service is. Therefore, the influence of the Wi-Fi service on the Beidou short message service can be effectively reduced by reducing the number of antennas used by the Wi-Fi service.

That is to say, the electronic device 100 detects that both the beidou short message chip and the Wi-Fi chip are in operation, where the Wi-Fi chip receives or sends signals using M antennas, where M is a positive integer greater than 1. The electronic device 100 detects that the Wi-Fi chip works in a preset interference channel, and the Wi-Fi chip receives or sends signals by using N antennas, wherein N is a positive integer smaller than M.

The Wi-Fi chip receives or sends signals by using N antennas, wherein N is a positive integer smaller than M.

In some possible application scenarios, both the beidou short message chip and the Wi-Fi chip of the electronic device 100 operate, wherein the working mode of the Wi-Fi chip is the MIMO mode. If the electronic device 100 detects that the Wi-Fi chip operates on a preset interference channel (e.g., channel 9 to channel 13 of the Wi-Fi 2.4GHz band). Electronic device 100 may switch the mode of operation from a MIMO mode to a single-input single-output (SISO) mode.

In the MIMO mode, the electronic device 100 receives and transmits signals of the Wi-Fi service through at least two antennas. In the SISO mode, the electronic apparatus 100 performs reception and transmission of signals of Wi-Fi services through one antenna. The interference of the Wi-Fi service to the Beidou short message service in the MIMO mode is higher than the interference of the Wi-Fi service to the Beidou short message service in the SISO mode because the Wi-Fi chip transmits and receives signals by using a plurality of antennas more greatly than the interference of a single antenna to the Beidou short message service. Therefore, the influence of the Wi-Fi service on the Beidou short message service can be reduced by switching the MIMO mode to the SISO mode.

For example, a Wi-Fi chip of electronic device 100 may switch a Wi-Fi connection from a MIMO mode to a SISO mode by negotiating with an Access Point (AP) device through an Action frame. Wherein, the Action frame can have bit carrying the working mode of switching Wi-Fi.

Alternatively, the electronic device 100 may negotiate with the AP device to switch the operation mode through the (Re) Association frame. The electronic device 100 may set a Modulation Coding Scheme (MCS) rate set corresponding to each of the MIMO mode and the SISO mode in the (Re) Association frame. Thus, the operation mode can be determined to be MIMO or SISO through different MCS indexes. Wherein each MCS index corresponds to a physical transmission rate under a set of parameters.

Alternatively, if the electronic device 100 operates in a Multiple Input Single Output (MISO) mode or a Single Input Multiple Output (SIMO) mode, the mode may be switched to the SISO mode.

In the embodiment of the present application, the avoidance schemes may be combined with each other, and are not limited herein.

For example, when the electronic device 100 switches from the MIMO mode to the SISO mode by the above-described back-off scheme that reduces the number of antennas used by the Wi-Fi chip. Since one of the antennas used by the Wi-Fi chip may not change when the electronic apparatus 100 switches from the MIMO mode to the SISO mode (e.g., the Wi-Fi chip uses the antenna 1301 and the antenna 1306 in fig. 12 in the MIMO mode, and the antenna used by the Wi-Fi chip is the antenna 1301 or the antenna 1306 after switching to the SISO mode). The electronic device 100 may also continue to employ the avoidance scheme (3), i.e., the electronic device 100 may switch the antenna used by the Wi-Fi chip to the TAS antenna (e.g., the antenna 1303) with the farthest euclidean distance from the antenna used by the beidou short message chip in the SISO mode. The electronic device 100 can also reduce the transmitting power of the Wi-Fi chip after switching the antenna used by the Wi-Fi chip, and further reduce the interference of the Wi-Fi service on the Beidou short message service.

In some possible embodiments, if the Wi-Fi chip of the electronic device 100 is operating in DBAC mode and MIMO mode simultaneously. The electronic device 100 may switch from MIMO to SISO mode. Alternatively, the electronic device 100 may disconnect a Wi-Fi connection that is preset to interfere with the new channel. Alternatively, the electronic device 100 may disconnect the Wi-Fi connection of the preset interference channel and establish the cellular communication connection. Alternatively, the electronic device 100 may disconnect the Wi-Fi connection on the preset interference channel and establish a Wi-Fi connection on a non-preset interference channel in the 2.4GHz band. Further, the electronic device 100 may switch the operation mode of the Wi-Fi chip from the MIMO mode to the SISO mode while establishing the Wi-Fi connection on the non-preset interference channel of the 2.4GHz band.

Fig. 14 shows a flowchart of a communication method provided in an embodiment of the present application. The electronic device 100 may include, among other things, a chip system 700 as shown in FIG. 7. The electronic device 100 may include multiple antennas as shown in fig. 12.

S1501, the electronic device 100 detects that the Wi-Fi chip 703 and the Beidou short message chip 702 work simultaneously.

S1502, the electronic device 100 determines whether to operate in a preset interference channel in the 2.4GHz band.

The step of determining whether the Wi-Fi operates in the preset interference channel in the 2.4GHz band by the electronic device 100 may refer to the embodiment shown in step S1102 of fig. 11, which is not described herein again. If the electronic device 100 determines that the Wi-Fi chip operates outside the preset interference channel range in the 2.4GHz band, the electronic device 100 executes step S1503. If the electronic device 100 determines that the Wi-Fi chip operates in the preset interference channel, the electronic device 100 executes step S1504.

S1503, the Wi-Fi chip 703 of the electronic device 100 is powered by default, and the antenna is powered by default.

The electronic device 100 determines that the working frequency range of the Wi-Fi chip is out of the frequency range of the preset interference channel, determines that the Wi-Fi service does not interfere with the beidou short message service, and determines that the default antenna (such as the antenna 1301 and the antenna 1306 shown in fig. 12) works with the default power for the Wi-Fi chip. And after the service execution of the Wi-Fi chip is finished, returning to the step S1502.

S1504, the electronic device 100 determines whether the Wi-Fi working mode is the MIMO mode.

When the electronic apparatus 100 determines that the Wi-Fi operates in the MIMO mode, step S1505 is performed. When the electronic apparatus 100 determines that the Wi-Fi is not operating in the MIMO mode, step S1506 is performed.

S1505, the electronic device 100 switches from the MIMO mode to the SISO mode.

The electronic device 100 determines that the working frequency range of the Wi-Fi chip is within the frequency range of the preset interference channel and works in the MIMO mode, the Wi-Fi service interferes with the Beidou short message service, and the MIMO mode of the Wi-Fi chip is switched to the SISO mode. The antenna used by the Wi-Fi chip is switched from multiple antennas (e.g., antenna 1301 and antenna 1306) used by default to one antenna (e.g., antenna 1301).

S1506, the electronic device 100 executes another avoidance scheme.

When the electronic device 100 determines that the Wi-Fi chip operates within the frequency range of the preset interference channel and does not operate in the MIMO mode, the electronic device 100 may perform one or more of the above-described avoidance schemes (1) to (3).

As described above, the above embodiments may be used in combination, and are not limited herein. For example, when the working mode of the Wi-Fi chip is switched from the MIMO mode in the 2.4GHz band to the SISO mode in the 2.4GHz band, the electronic device 100 may further reduce the influence of the Wi-Fi service on the beidou short message service by combining the above avoidance scheme for switching the transmitting antenna.

In one possible implementation manner, when the beidou short message chip of the electronic device 100 is in the working state. When electronic device 100 receives an input to establish a Wi-Fi connection, electronic device 100 may establish a Wi-Fi connection in the 5GHz band in response to the input. Or establishing the Wi-Fi connection of the 2.4GHz frequency band working in the SISO mode. Or, the transmission power is reduced and/or a transmission antenna with higher isolation is used while establishing the Wi-Fi connection of the 2.4GHz frequency band. Or, establishing the Wi-Fi connection on a non-preset interference channel of the 2.4GHz frequency band. Therefore, the avoidance operation can be executed before the Beidou short message chip starts to receive signals, and the Beidou short message service is further prevented from being influenced by the Wi-Fi service.

Optionally, after the electronic device 100 receives the input for establishing the Wi-Fi connection, in response to the input, the electronic device 100 may suspend receiving the signal when the beidou short message chip sends the signal, suspend sending the signal when the beidou short message chip receives the signal, and/or reduce the transmission power, and/or use a transmission antenna with higher isolation after establishing the Wi-Fi connection in the 2.4GHz band.

Next, system-on-chip 1550 is described in conjunction with FIG. 15.

Illustratively, as shown in fig. 15, the chip system 1550 may include: an application processor 1551, a Beidou short message chip 1552 and a Wi-Fi chip 1553. The chip system 1550 may be applied to the electronic device 100. Wherein:

the application processor 1551 of the electronic device 100 can communicate with the beidou short message chip 1552 through an interface (e.g., PCIE). The application processor 1551 of the electronic device 100 may also communicate with a Wi-Fi chip 1553 via an interface (e.g., PCIE, SDIO).

For detailed description of the application processor 1551, the beidou short message chip 1552 and the Wi-Fi chip 1553, reference may be made to the embodiment illustrated in fig. 7, which is not described herein again. In the chip system 1550, the Wi-Fi chip 1553 and the beidou short message chip 1552 can communicate with each other through the application processor 1551. The electronic device 100 may also implement the avoidance schemes provided by the above embodiments through the chip system 1550.

In a possible implementation manner, the electronic device 100 may preset a sequence in which the electronic device 100 uses the various avoidance schemes, and the electronic device 100 executes the avoidance schemes based on the sequence of the avoidance schemes. For example, the electronic device 100 may set the avoidance scheme (4) to be executed first, then the avoidance scheme (3) to be executed, then the avoidance scheme (2) to be executed, and finally the avoidance scheme (1) to be executed. When the electronic device 100 does not use multiple antennas, the electronic device 100 cannot use the avoidance scheme (4), and the electronic device 100 attempts to use the avoidance scheme (3). When the electronic device 100 has no other antennas to switch use, the electronic device 100 attempts to use the avoidance scheme (2). When the electronic device 100 cannot transmit or receive signals of the current Wi-Fi service through the communication connection of the other frequency band, the electronic device 100 uses the avoidance scheme (1).

In one possible implementation, the electronic device 100 may use a plurality of the avoidance schemes (1) to (4) described above at the same time. For example, the electronic device 100 operates in the MIMO mode, and the operating channel is a preset interference channel of a 2.4GHz band. The electronic apparatus 100 may switch the operation mode from MIMO to SISO after switching the Wi-Fi connection on the preset interference channel to the Wi-Fi connection on the non-preset interference channel, and switch the antenna used by the Wi-Fi service in the SISO mode to an antenna with higher isolation. The W-iFi chip can also pause receiving signals when the Beidou short message chip sends signals, and pause sending signals when the Beidou short message chip receives signals.

In a possible implementation manner, the electronic device 100 may determine whether the Wi-Fi chip and the beidou short message chip are working at the same time after determining that the Wi-Fi chip is working in the preset interference channel. The method and the device do not limit the sequence of the two steps of judging whether the Wi-Fi chip works in the preset interference channel and judging whether the Wi-Fi chip and the Beidou short message chip work simultaneously.
