The occurrences of this phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is understood explicitly and implicitly by those skilled in the art that the embodiments described herein can be combined with other embodiments.

The mobile terminals involved in the embodiments of the present application may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to wireless modems, as well as various forms of user equipment (User Equipment, UE), mobile station (Mobile Station, MS), terminal device (terminal device) and so on. For convenience of description, the devices mentioned above are collectively referred to as mobile terminals.

The following describes the embodiments of the present application in detail.

Please refer to FIG. 1 . FIG. 1 is a schematic flowchart of a method for switching antennas disclosed in an embodiment of the present application. As shown in FIG. 1 , the method for switching antennas includes the following steps.

101. When the mobile terminal is in a call state, the mobile terminal detects whether the mobile terminal is in a screen-off state or in an approaching state. If yes, execute step 102; if not, execute step 104.

In the embodiment of the present application, the call state refers to the state that the mobile terminal is connected to the phone. Generally speaking, when the mobile terminal receives an incoming call, the user will connect the incoming call and hold the mobile terminal to answer it. Since the user generally holds the mobile terminal close to the user's ear when holding a mobile phone call, the proximity sensor of the mobile terminal can detect an object approaching, and the mobile terminal is in a blocking approach state. If the mobile terminal is not in the off-screen state or blocked approach state, the mobile terminal may be in hands-free mode, and the user may not be holding the mobile terminal. At this time, the transceiver performance of the antenna will not be weakened by the user's holding, and antenna switching will not be performed. .

When the mobile terminal is in the call state, when it is detected that the mobile terminal is in the blocking and approaching state, in order to reduce the power consumption of the screen display of the mobile terminal, the screen of the mobile terminal will be turned off, thereby automatically setting the mobile terminal to a screen-off state. The embodiment of the present application only needs to detect that the mobile terminal is in the hold state only when it is detected that the mobile terminal is in the off-screen state or in the blocking approach state, and can quickly determine whether the mobile terminal is in the hold state when the mobile terminal is in the call state. Whether the mobile terminal is in a holding state can be quickly judged according to the user's habit of answering calls.

It should be noted that the screen-off state in the embodiment of the present application refers to the screen-off state automatically set by the mobile terminal, not the screen-off state manually set by the user.

Wherein, the proximity sensor may also be referred to as a distance sensor, and is used to detect the distance between the mobile terminal and the measured object. The proximity sensor can emit and emit infrared light pulses, and calculate the distance between the mobile terminal and the measured object according to the time difference between receiving and emitting infrared light pulses and the propagation speed of the infrared light pulses. Wherein, the object to be measured may be any object capable of blocking infrared rays, such as a person's head, face, and the like. When the proximity sensor detects that the distance between the mobile terminal and the measured object is less than the preset distance threshold, it is considered that the mobile terminal has an object approaching, and the mobile terminal is considered to be in a blocking approach state.

The preset distance threshold can be set in advance and stored in the non-volatile memory of the mobile terminal. For example, the preset distance threshold may be set to 5 centimeters.

102. The mobile terminal detects whether the received signal strength of the mobile terminal is less than a preset strength threshold. If yes, execute step 103; if not, execute step 104.

In the embodiment of the present application, the received signal strength of the mobile terminal refers to the magnitude of the RSSI of the mobile terminal.

Wherein, the received signal strength indicator (Received Signal Strength Indicator, RSSI) is used to measure the signal strength received by the mobile terminal, and the unit of RSSI may be dBm or asu. Among them, dBm represents the absolute value of power, and the signal strength is generally a negative number, and the smaller the absolute value, the stronger the signal strength. asu is a unique signal unit defined, the larger the value, the stronger the signal strength.

The preset intensity threshold can be set in advance and stored in the non-volatile memory of the mobile terminal. For example, the preset intensity threshold can be set to -90dBm.

If the received signal strength of the mobile terminal is lower than the preset strength threshold, it indicates that the transmitting and receiving performance of the antenna currently used by the mobile terminal for calling is poor, and antenna switching is required. If the received signal strength of the mobile terminal is greater than or equal to the preset strength threshold, it indicates that the antenna currently used by the mobile terminal for calling has a good sending and receiving performance, and there is no need to perform antenna switching.

103. If the antenna currently used by the mobile terminal for calls is the first antenna, the mobile terminal switches the antenna currently used by the mobile terminal for calls from the first antenna to the second antenna.

In the embodiment of the present application, the mobile terminal may adopt dual antennas, wherein the first antenna is located at the bottom of the mobile terminal and may also be called the lower antenna, and the second antenna is located at the top of the mobile terminal and may also be called the upper antenna. Both the first antenna and the second antenna can be used for transmitting and receiving mobile signals. Generally, in order to reduce the impact of electromagnetic radiation on the human body, the lower antenna (ie, the first antenna) is preferentially used for signal transmission and reception.

The antenna currently used by the mobile terminal for calls is the first antenna, which refers to the use of the first antenna for signal transmission and reception. Of course, the mobile terminal can also use other antennas to assist in signal reception. At this time, the first antenna is the main antenna. antenna, and other antennas (for example, the second antenna) are auxiliary antennas.

If the antenna currently used by the mobile terminal for calls is the first antenna, when the mobile terminal is in a call state, the user will generally hold the lower half of the mobile terminal, that is, the user's holding posture will affect the performance of the first antenna, However, the impact of the holding posture on the second antenna is significantly smaller than that of the first antenna. If the received signal strength of the mobile terminal is lower than the preset strength threshold, that is, when the first antenna used by the mobile terminal for calls has poor transceiver performance, the mobile terminal will An antenna currently used by the mobile terminal for calls is switched from the first antenna to the second antenna, thereby improving call quality.

The antenna currently used by the mobile terminal for calls is the second antenna, which refers to the use of the second antenna for signal transmission and reception. Of course, the mobile terminal can also use other antennas to assist in signal reception. At this time, the second antenna is the main antenna, and other antennas (for example, the first antenna) are auxiliary antennas.

When the antenna is switched from the first antenna to the second antenna, corresponding antenna configuration parameters will also change accordingly. For example, the antenna configuration parameters may include the lobe width of the antenna, the frequency range of the antenna, the transmit power of the antenna, and the like.

Optionally, step 101 and step 102 can be performed at the same time. When the mobile terminal is in a call state, it only needs to be detected that the mobile terminal is in a screen-off state or in an approaching state, and the received signal strength of the mobile terminal is less than a preset strength threshold, that is, Step 103 may be executed to perform antenna switching.

104. End this process.

In the embodiment of the present application, when the mobile terminal is in the call state, if it is detected that the mobile terminal is in the off-screen state or in the approaching state, it can be confirmed that the mobile terminal is in the holding state. If it is detected that the signal of the mobile terminal is weak, it will move The antenna currently used by the terminal for calls is switched from the first antenna to the second antenna, thereby improving call quality.

In this embodiment of the present application, the wireless headset may be a Bluetooth headset. In the present application, in the scene where the user is answering the phone with the earphone, even if it is detected that the mobile terminal is in the off-screen state or in the blocking approach state, the antenna switching will not be performed. For example, when the user puts the mobile terminal on the table with the screen facing down, the mobile terminal is not in a holding state. The embodiment of the present application can avoid false triggering of antenna switching.

204. If the antenna currently used by the mobile terminal for calls is the first antenna, the mobile terminal switches the antenna currently used by the mobile terminal for calls from the first antenna to the second antenna.

205. End this process.
