[0027] see figure 1 , the first embodiment of the present invention provides a method for determining the state of being held, which is applied to a mobile terminal, and the two sides of the mobile terminal are respectively provided with a first antenna and a second antenna. The method includes:

[0028] Step 101, acquiring a first standing wave ratio variable of a first antenna and a second standing wave ratio variable of a second antenna.

[0029] The full name of the standing wave ratio (SWR) is the voltage standing wave ratio (Voltage Standing Wave Ratio, VSWR). In radio communication, if the impedance of the antenna and the feeder does not match or the impedance of the antenna and the transmitter does not match, the high-frequency energy will generate a reflected wave in the antenna, and the reflected wave and the incident wave will converge in the antenna feed system to generate a standing wave. The VSWR is numerically approximately equal to the ratio of the output impe...

[0056] Step 801, acquire a first standing wave ratio variable of the first antenna and a second standing wave ratio variable of the second antenna.

[0057] Among them, when the human hand is close to the antenna, the dielectric constant of the human hand will increase the equivalent dielectric constant around the antenna, and the conductivity of the human hand will increase the dielectric loss around the antenna, thereby shifting the resonant frequency of the antenna to a low frequency , that is, the standing wave ratio of the antenna will shift to the low frequency and sink; the result of the standing wave ratio shifting to the low frequency is that the standing wave ratio of the...

Abstract

The invention provides a method for determining gripped states and a mobile terminal. The method is applied to the mobile terminal. A first antenna and a second antenna are arranged on two sides of the mobile terminal respectively. The method includes acquiring first standing-wave ratio variables of the first antenna and second standing-wave ratio variables of the second antenna; determining the gripped states of the mobile terminal according to the first standing-wave ratio variables and / or the second standing-wave ratio variables. The method and the mobile terminal in an embodiment of the invention have the advantages that the standing-wave ratio variables of the antennas on the two sides of the mobile terminal are acquired, and the gripped states of the mobile terminal can be judged by the aid of the standing-wave ratio variables; judgment procedures are simple, and capacitance sensors can be omitted; judgment results are high in accuracy, and initial standing-wave ratios can be debugged and corrected; the problems of increase of cost and interference with existing antennas due to the fact that existing gripped states of existing mobile terminals are judged by the aid of capacitance sensors can be solved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for determining a held state and a mobile terminal. Background technique [0002] With the development of mobile communication technology, mobile terminals such as mobile phones have gradually become an indispensable part of people's lives, and also provide great convenience for people's work. The size of the mobile terminal screen is also becoming larger and larger. In some specific scenarios, the mobile terminal needs to determine whether the user's holding state is left-handed or right-handed, such as in a one-handed operation mode. In the prior art, the holding condition of the left and right hands is mainly determined through the detection of the capacitive sensor. Generally, capacitive sensors are added to the left and right sides or left and right corners of the mobile terminal, and the left and right hands are used to judge the difference in capacit...
