This disclosure relates to the technical field of electronic devices, and particularly to a method for electromagnetic interference control and related devices.
With the development of mobile communication technology, users have an increasing demand for communication with electronic devices such as mobile phones. Currently, electronic devices on the market generally transmit data through cellular mobile network communications or wireless fidelity (Wi-Fi) communications. However, full-screen mobile phones are facing problems like radio frequency interference. An integrated driver chip of a display screen of the full-screen mobile phone has extended to an antenna clearance area, and in this case, frequency multiplication/division of a mobile industry processor interface (MIPI) frequency of the display screen can cause interference to a radio frequency antenna, which results in a relatively low total isotropic sensitivity (TIS) of the antenna.

In response to detecting that the electronic device is in a preset scene, electromagnetic interference between a radio frequency system and a display screen of the electronic device is detected, where the preset scene includes a game scene. In response to the detected electromagnetic interference, a real-time requirement of the preset scene is determined. An interference control strategy adapted to the real-time requirement of the preset scene is obtained. Electromagnetic interference of a mobile industry processor interface (MIPI) of the display screen to the radio frequency system is reduced or eliminated based on the interference control strategy.

Hereinafter, implementations of the disclosure will be described in detail.
According to implementations, a method for electromagnetic interference control and related devices are provided, which can improve stability of communication of an electronic device in a game scene.
At present, an electronic device 101 may be connected to a base station 103 and/or a wireless hotspot 102, as illustrated in
At block S201, in response to detecting that the electronic device is in a preset scene, the electronic device detects electromagnetic interference between a radio frequency system and a display screen of the electronic device, where the preset scene includes a game scene.
When the electronic device communicates with a wireless hotspot, the radio frequency system may select different communication channels for data transmission. Each communication channel corresponds to a frequency domain resource defined by a protocol (e.g., a global system for mobile communication (GSM) frequency band, an LTE B8/B20/B28 frequency band, etc.). According to relevant communication protocols, the electronic device can use one or more different communication channels in a same service processing period when the electronic device handles different services. The electronic device in a preset scene may refer to that the electronic device is in a game scene, for example, the electronic device runs a game App by using Wi-Fi data. Upon detecting that the electronic device is in the preset scene, a Wi-Fi module reports in real time information of a channel(s) currently working.
At block S202, in response to the detected electromagnetic interference, the electronic device determines a real-time requirement of the preset scene.
Depending on the capability of a chip, a mobile industry processor interface (MIPI) frequency of the display screen may support different frequencies or frequency bands, such as 514.5 MHz, 516.5 MHz, and so on. When running a game APP through Wi-Fi, there will be interference between an MIPI of the display screen and a Wi-Fi channel if frequency conflict occurs.
At block S203, the electronic device obtains an interference control strategy adapted to the real-time requirement of the preset scene.
According to the real-time requirement determined at block S202, a preconfigured interference control strategy corresponding to the determined real-time requirement is obtained.
At block S204, the electronic device reduces or eliminates electromagnetic interference of an MIPI of the display screen to the radio frequency system based on the interference control strategy.
In some implementations, according to the interference control strategy corresponding to the determined real-time requirement, select a target frequency with no interference or the minimum interference for frequency hopping, switch to a data network, or negotiate channel switching with a router to avoid interference.
In implementations of the disclosure, the electronic device detects electromagnetic interference between a radio frequency system and a display screen of the electronic device in response to detecting that the electronic device is in a preset scene, where the preset scene includes a game scene. The electronic device determines a real-time requirement of the preset scene in response to the detected electromagnetic interference. The electronic device obtains an interference control strategy adapted to the real-time requirement of the preset scene. The electronic device reduces or eliminates electromagnetic interference of an MIPI of the display screen to the radio frequency system based on the interference control strategy. As can be seen, after detecting that there is electromagnetic interference between the radio frequency system and the display screen, the electronic device can adopt, according to a current scene (i.e., detected scene), the interference control strategy to perform interference control. In this way, electromagnetic interference of the MIPI of the display screen to the radio frequency system can be eliminated or reduced, thereby improving stability of communication in the game scene and facilitating obtaining the best game experience.
In some implementations, electromagnetic interference between the radio frequency system and the display screen of the electronic device is detected as follows. At least one detection value of a first frequency and a detection value of a second frequency are obtained, where the first frequency is a communication frequency of the radio frequency system, and the second frequency is an MIPI frequency of the display screen. According to a preset interference channel list, the at least one detection value of the first frequency and the detection value of the second frequency, electromagnetic interference between the radio frequency system and the display screen of the electronic device is determined, where the preset interference channel list contains levels of interference (i.e., interference level) of an operating frequency of the MIPI of the display screen on different channels.
The preset interference channel list contains magnitudes and levels of interference of different operating frequencies of the MIPI of the display screen to different Wi-Fi channels. Based on the detection value of the second frequency and the at least one detection value of the first frequency, determine, in the interference channel list, whether there is a detection value of the first frequency causing interference with respect to the detection value of the second frequency, so as to determine whether there is electromagnetic interference between the radio frequency system and the display screen. If there is a detection value of the first frequency causing interference with respect to the detection value of the second frequency, determine that there is electromagnetic interference. If there is no detection value of the first frequency causing interference with respect to the detection value of the second frequency, determine that there is no electromagnetic interference.
In some implementations, the at least one detection value of the first frequency and the detection value of the second frequency may be obtained as follows. When running a game APP, a Wi-Fi module reports information (e.g., first frequency) of at least one channel currently working to the AP. After receiving the information of the at least one channel, the AP obtains a current MIPI frequency (i.e., second frequency) of the screen.
As can be seen, the electronic device can perform frequency comparison based on the interference channel list, to quickly determine whether there is electromagnetic interference between a frequency currently used by the MIPI of the display screen and any of the at least one detection value of the first frequency. In this way, an electromagnetic interference scene can be determined quickly based on a real-time detection value, thereby improving detection efficiency.
In some implementations, the electronic device includes a central processing unit (CPU). The real-time requirement of the preset scene is determined as follows. The load of the CPU (i.e., CPU load) corresponding to the preset scene is detected. The real-time requirement of the preset scene is determined according to the detected load.
After the CPU load corresponding to the preset scene is detected, the real-time requirement of the preset scene can be determined according to the detected CPU load and the preset CPU load corresponding to different real-time requirements. For example, the real-time CPU load (i.e., detected CPU load) corresponding to the preset scene can be obtained from a task manager, which is 5-10%, and if the preset CPU load corresponding to a high real-time requirement is greater than 5%, it can be determined that the preset scene currently running has a high real-time requirement.
In some implementations, a value of the (preset) CPU load corresponding to a high real-time requirement can be set in advance according to the historical CPU load (i.e., previous CPU load) corresponding to different real-time requirements of the preset scene, which is not limited in the disclosure.
As can be seen, the electronic device can determine, according to the CPU load corresponding to the preset scene and the CPU load corresponding to different real-time requirements of the preset scene, the real-time requirement of the preset scene when the electronic device is in the preset scene, so as to determine a real-time requirement of the preset scene in the presence of electromagnetic interference.
In some implementations, the electronic device includes a graphic processing unit (GPU). The real-time requirement of the preset scene is determined as follows. The load of the GPU (i.e., GPU load) corresponding to the preset scene is detected. The real-time requirement of the preset scene is determined according to the detected load.
After the GPU load corresponding to the preset scene is detected, the real-time requirement of the preset scene can be determined according to the detected GPU load and the preset GPU load corresponding to different real-time requirements. For example, the real-time GPU load (i.e., detected GPU load) corresponding to the preset scene can be obtained from a task manager, which is 5-10%, and if the preset GPU load corresponding to a high real-time requirement is greater than 3%, it can be determined that the preset scene currently running has a high real-time requirement.
In some implementations, a value of the (preset) GPU load corresponding to a high real-time requirement can be set in advance according to the historical GPU load (i.e., previous GPU load) corresponding to different real-time requirements of the preset scene, which is not limited in the disclosure.
As can be seen, the electronic device can determine, according to the GPU load corresponding to the preset scene and the GPU load corresponding to different real-time requirements of the preset scene, the real-time requirement of the preset scene when the electronic device is in the preset scene, so as to determine a real-time requirement of the preset scene in the presence of electromagnetic interference.
In some implementations, the electronic device includes a game module. The real-time requirement of the preset scene is determined as follows. The game module detects whether the preset scene is a preset scene with a high real-time requirement.
As can be seen, the electronic device can determine, according to a real-time parameter of the game module and the preset scene, the real-time requirement of the preset scene when the electronic device is in the preset scene.
In some implementations, the interference control strategy adapted to the real-time requirement of the preset scene is obtained as follows. Query a preset interference-control-strategy set, where the interference-control-strategy set contains a correspondence relationship between interference control strategies and scenes with different real-time requirements. An interference control strategy corresponding to a scene with a high real-time requirement is obtained in condition of the preset scene with the high real-time requirement. An interference control strategy corresponding to a scene with a low real-time requirement is obtained in condition of the preset scene with the low real-time requirement.
An interference control strategy adopted by the electronic device varies with the real-time requirement. After the real-time requirement of the preset scene is determined, an interference control strategy corresponding to the determined real-time requirement is invoked from different interference control strategies corresponding to different real-time requirements.
As can be seen, the electronic device can adopt an interference control strategy corresponding to the real-time requirement of the preset scene, which can improve diversity and efficiency of an electromagnetic interference resolution mechanism, thereby improving stability of communication of the radio frequency system.
In some implementations, according to the interference control strategy corresponding to the scene with the high real-time requirement, the following is performed. An available frequency range or an available frequency of an MIPI frequency of the display screen is obtained. A first-frequency set is obtained, where the first-frequency set contains a frequency of at least one wireless channel used by the electronic device in the preset scene. According to the first-frequency set and any one of the available frequency range and the available frequency, a target frequency of the MIPI frequency of the display screen is determined. The MIPI frequency of the display screen is adjusted to the target frequency.
The electronic device can determine a target frequency according to at least one communication frequency enabled in the preset scene and any one of the available frequency range and the available frequency of the MIPI frequency of the display screen, where the target frequency has no interference or the minimum interference with any frequency in the first-frequency set. The wireless channel herein may be a wireless Wi-Fi channel. As an example, when a user is playing a game by using Wi-Fi data, if the electronic device is in a scene (e.g., team battles) with a high real-time requirement, the MIPI frequency of the display screen is 514.5 MHz, which has electromagnetic interference with a wireless Wi-Fi channel frequency, then frequency hopping is performed on the MIPI frequency of the display screen such that the MIPI frequency is in a frequency range that has no interference with the current wireless Wi-Fi channel frequency.
As can be seen, the electronic device can determine, according to the first-frequency set and any one of the available frequency range and the available frequency of the MIPI frequency of the display screen, the target frequency of the MIPI frequency, so as to avoid the radio frequency system of the electronic device in the current scene (i.e., detected preset scene) from being interfered by the MIPI of the display screen because the radio frequency system uses any frequency in the first-frequency set, thereby improving stability of communication of the radio frequency system.
In some implementations, network switching is performed as follows. An MIPI frequency of the display screen and an operating frequency of at least one data network are obtained. A target data network is determined according to the operating frequency of the at least one data network and the MIPI frequency of the display screen, where the target data network is one of the at least one data network which has the minimum interference with the MIPI frequency of the display screen. Switch data network according to the target data network.
According to the MIPI frequency of the display screen and the operating frequency of the at least one data network, the electronic device can determine, based on the channel interference list, a data network that causes no interference or the least interference to the MIPI frequency of the display screen as the target data network. Thus, the operating frequency of the target data network determined by the electronic device will has little or no electromagnetic interference with the MIPI frequency of the display screen. As an example, when a user is playing a game by using Wi-Fi data, if the electronic device is in a scene (e.g., team battles) with a high real-time requirement and the MIPI frequency has electromagnetic interference with a wireless Wi-Fi channel frequency, a wireless Wi-Fi network is switched to a data network to avoid interference.
As can be seen, according to the operating frequency of the at least one data network and the MIPI frequency of the display screen, the electronic device can determine the target data network, which causes the least interference to the MIPI frequency of the display screen, for network switch, so as to avoid the radio frequency system of the electronic device in the current scene from being interfered by the MIPI of the display screen because the radio frequency system uses a frequency of the fixed data network, thereby improving stability of communication of the radio frequency system.
In some implementations, network switching is performed as follows. An MIPI frequency of the display screen and an operating frequency of at least one wireless channel are obtained. A target wireless channel is determined according to the operating frequency of the at least one wireless channel and the MIPI frequency of the display screen, where the target wireless channel is one of the at least one wireless channel which has the minimum interference with the MIPI frequency of the display screen. Switch wireless channel according to the target wireless channel.
According to the MIPI frequency of the display screen and the operating frequency of the at least one wireless channel, the electronic device can determine, based on the channel interference list, a wireless channel that causes no interference or the least interference to the MIPI frequency of the display screen as the target wireless channel. Thus, the operating frequency of the target wireless channel determined by the electronic device will has little or no electromagnetic interference with the MIPI frequency of the display screen. The wireless channel may be a wireless Wi-Fi channel. As an example, when a user is playing a game by using Wi-Fi data, if the electronic device is in a scene (e.g., team battles) with a high real-time requirement and the MIPI frequency of the display screen has electromagnetic interference with a wireless Wi-Fi channel frequency, negotiate channel switching with a router to avoid interference.
As can be seen, according to the operating frequency of the at least one wireless channel and the MIPI frequency of the display screen, the electronic device can determine the target wireless channel, which causes the least interference to the MIPI frequency of the display screen, for negotiating wireless channel switching with the router, so as to avoid the radio frequency system of the electronic device in the current scene from being interfered by the MIPI of the display screen because the radio frequency system uses any frequency in the first-frequency set, thereby improving stability of communication of the radio frequency system.
