The following describes a software environment to which the control method provided by the embodiment of the present invention is applied, by taking an android operating system as an example.
Fig. 1 is a schematic diagram of an architecture of a possible android operating system according to an embodiment of the present invention. In fig. 1, the architecture of the android operating system includes 4 layers, which are respectively: an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, a Linux kernel layer).
The application program layer comprises various application programs (including system application programs and third-party application programs) in an android operating system.
The application framework layer is a framework of the application, and a developer can develop some applications based on the application framework layer under the condition of complying with the development principle of the framework of the application.
The system runtime layer includes libraries (also called system libraries) and android operating system runtime environments. The library mainly provides various resources required by the android operating system. The android operating system running environment is used for providing a software environment for the android operating system.
The kernel layer is an operating system layer of an android operating system and belongs to the bottommost layer of an android operating system software layer. The kernel layer provides kernel system services and hardware-related drivers for the android operating system based on the Linux kernel.
Taking an android operating system as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the control method provided in the embodiment of the present invention based on the system architecture of the android operating system shown in fig. 1, so that the control method may operate based on the android operating system shown in fig. 1. Namely, the processor or the terminal can implement the control method provided by the embodiment of the invention by running the software program in the android operating system.
The terminal device in the embodiment of the invention can be a mobile terminal device and can also be a non-mobile terminal device. The mobile terminal device may be a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted terminal, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), etc.; the non-mobile terminal device may be a Personal Computer (PC), a Television (TV), a teller machine, a self-service machine, or the like; the embodiments of the present invention are not particularly limited.
The execution main body of the control method provided by the embodiment of the present invention may be the terminal device (including a mobile terminal device and a non-mobile terminal device), or may also be a functional module and/or a functional entity capable of implementing the method in the terminal device, which may be specifically determined according to actual use requirements, and the embodiment of the present invention is not limited. The following takes a terminal device as an example to exemplarily explain a control method provided by the embodiment of the present invention.
Referring to fig. 2, an embodiment of the present invention provides a control method, which may include steps 201 to 202 described below.
At different times, the communication frequency bands in which the terminal device operates may be different, so that the terminal device needs to obtain the target communication frequency band in which the terminal device currently operates for many times.
Optionally, the terminal device may periodically and actively acquire the target communication frequency band according to a preset period, for example, the terminal device sends a first message for acquiring the target communication frequency band to a radio frequency module in the terminal device. And after receiving the first message, the radio frequency communication module acquires a target communication frequency band and sends a second message to the terminal equipment, wherein the second message comprises the target communication frequency band. And the terminal equipment receives the second message and obtains the target communication frequency band from the second message.
Optionally, the terminal device may passively acquire the target communication frequency band, for example, when a radio frequency module in the terminal device detects that a communication frequency band in which the terminal device currently operates changes, the radio frequency module acquires the target communication frequency band and sends a notification message to the terminal device, where the notification message includes the target communication frequency band. The terminal device receives the notification information and obtains the target communication frequency band from the notification information.
The grounding or grounding via the capacitor can reduce interference, and the suspension can reduce the influence on the performance of the antenna.
Optionally, the shell of the USB interface is suspended, that is, not grounded, so that the shell of the USB interface becomes a part of the antenna, thereby avoiding affecting the performance of the antenna.
Optionally, the shell of the USB interface is grounded, that is, the shell of the USB interface is directly grounded; the shell of the USB interface is grounded through a capacitor, namely the shell of the USB interface is grounded through the capacitor.
Illustratively, this step 202 may be specifically realized by the step 202a or the step 202b described below.
Step 202a, under the condition that the target communication frequency band is the same as the first communication frequency band in the preset communication frequency band, the terminal device controls the shell of the USB interface to be grounded or grounded through a capacitor.
Illustratively, the terminal device outputs a first control signal to a first control unit of the shell of the USB interface to control the shell of the USB interface to be grounded or grounded via a capacitor.
The first control signal may be a high level signal or a low level signal, which is set according to practical situations, and the embodiment of the present invention is not limited. The first control signal makes the first control unit control the shell of the USB interface to be grounded or grounded through a capacitor. Exemplary first control units may be switching circuits, such as diode switching circuits, triode switching circuits, field effect transistor switching circuits, and the like, and embodiments of the present invention are not limited thereto. In this case, the switch circuit may be closed by the first control signal, and the shell of the USB interface may be grounded or grounded via a capacitor.
Step 202b, under the condition that the target communication frequency band is different from any one of the preset communication frequency bands, the terminal device controls the shell of the USB interface to be suspended.
Illustratively, the terminal device outputs a second control signal to a second control unit of the shell of the USB interface to control the shell of the USB interface to be suspended.
The second control unit may be the same as or different from the first control unit. The second control signal may be the same as or different from the first control signal.
The second control signal may be a high level signal or a low level signal, which is set according to practical situations, and the embodiment of the present invention is not limited. The second control signal makes the second control unit control the shell of the USB interface to be suspended. The exemplary second control unit may also be a switch circuit, such as a diode switch circuit, a triode switch circuit, a field effect transistor switch circuit, etc., and the embodiment of the present invention is not limited. At this time, the second control signal may turn off the switch circuit, and the shell of the USB interface is suspended.
For example, taking the terminal device as a mobile phone as an example, as shown in table 1 and table 2, statistics show that the charging interference of the mobile phone often has a large influence on low frequency bands (e.g., bands B28, B5, B8, etc.), and has a small influence on medium and high frequencies. The capacitor is connected in parallel with the shell of the USB interface, so that the charging interference is greatly improved, and the interference value can be reduced to be within 5 dB; however, the parallel capacitance has a large influence on the antenna performance in the intermediate frequency band (e.g., bands B1, B3, etc.), and the problem of the influence is more serious than that of the charging interference. Therefore, when the target communication frequency band obtained by the terminal device is a low frequency band (i.e. the first communication frequency band), the terminal device controls the shell of the USB interface to be grounded; and when the target communication frequency band obtained by the terminal equipment is the intermediate frequency band, the terminal equipment controls the shell of the USB interface to be suspended. And then can guarantee to charge when disturbing, also can guarantee to influence minimum to antenna performance when communicating.

For example, referring to fig. 2, as shown in fig. 3, before step 201, the control method provided in the embodiment of the present invention may further include the following step 203; the step 201 can be specifically realized by the step 201a described below.
For example, the terminal device detects whether a USB cable is inserted into the USB interface, and detects whether a current signal or a data signal is transmitted from the USB cable to the terminal device.
Illustratively, when it is detected that a charging signal exists at the USB interface, the terminal device obtains the target communication frequency band in which the terminal device is currently operating, and when the target communication frequency band is the same as a first communication frequency band in the preset communication frequency band, the terminal device controls a shell of the USB interface to be grounded or grounded through a capacitor; and under the condition that the target communication frequency band is different from any one of the preset communication frequency bands, the terminal equipment controls the shell of the USB interface to be suspended. The specific grounding circuit refers to the related art and is not described herein.
For example, when detecting that a data transmission signal (at this time, a charging signal) exists in the USB interface, the terminal device obtains the target communication frequency band in which the terminal device is currently operating, and when the target communication frequency band is the same as a first communication frequency band in the preset communication frequency band, the terminal device controls a shell of the USB interface to be grounded or grounded via a capacitor; and under the condition that the target communication frequency band is different from any one of the preset communication frequency bands, the terminal equipment controls the shell of the USB interface to be suspended. The specific grounding circuit refers to the related art and is not described herein.
Under the condition that the charging signal or the charging signal and the data transmission signal do not exist in the USB interface, the terminal equipment can control the shell of the USB interface to be suspended so as to ensure that the performance of the antenna is not influenced.
Therefore, the terminal device can determine the connection mode of the shell of the USB interface by combining whether the USB interface has the charging signal or the data transmission signal and the relation between the target communication frequency band and the preset communication frequency band, and can further reduce the interference and the influence on the antenna performance to a certain extent.
The embodiment of the invention provides a control method, wherein terminal equipment acquires a target communication frequency band of the current work of the terminal equipment; controlling a shell of a Universal Serial Bus (USB) interface in the terminal equipment to execute one of the following connection modes according to the target communication frequency band and a preset communication frequency band: grounded, grounded through a capacitor and suspended. According to the scheme, the shell of the USB interface is controlled to execute one of the following connection modes according to the relation between the current working target communication frequency band of the terminal equipment and the preset communication frequency band: grounding, grounding through the capacitor and suspending, the connection mode of the shell of the USB interface can be considered from the current working target communication frequency band of the terminal equipment, so that the problems of interference when the USB interface is adopted for charging and influence on the antenna performance can be comprehensively considered, the connection mode of the shell of the USB interface is determined, the problem that the capacitor is directly connected in parallel on the shell of the USB interface can be solved to a certain extent, although the interference when the USB interface is adopted for charging can be effectively improved, the problem that the antenna performance is greatly influenced can be caused.
