Description
Technical Field
The present invention relates to wireless communication technologies of mobile terminals, and in particular, to a method and an apparatus for adjusting antenna switching.
Background
The integrated function is multiple, and the supported frequency band is multiple, so that the development trend of the intelligent mobile communication terminal is achieved, and good experience is brought to users. Due to the increasing number of wireless frequency bands integrated in a limited size, the frequency range from 700MHz to 5GHz is wide, and at the same time, the number of functional parts of the mobile terminal is increasing, such as: liquid Crystal Display (LCD), touch screen, motor, Speaker, main/sub camera, flash lamp, Universal Serial Bus (USB), fingerprint identification, etc. In many application scenarios, due to the circuit design of the mobile terminal or inherent defects of the mobile terminal, the problem that some frequency bands are interfered by some components is inevitably encountered, which is difficult to effectively solve.
In order to enhance the receiving performance of the mobile terminal, a first antenna, that is, a main set antenna and a second antenna, that is, a diversity antenna, are usually designed and reserved on the mobile terminal, wherein the main set antenna can implement the transmission and reception of wireless signals of the mobile terminal, and the diversity antenna can implement the reception of wireless signals of the mobile terminal; in the default state, the main set antenna and the diversity antenna are both opened to work normally. The main set antenna and the diversity antenna are generally located at different positions of the mobile terminal, respectively, and are usually located relatively far away from a certain functional component, for example, the front camera is close to the diversity antenna located at the top of the mobile terminal, and is far away from the main set antenna located at the bottom.
In the development process of the mobile terminal, the coupling receiving sensitivity of the diversity antenna with multiple systems and multiple frequency bands is seriously interfered when the front-facing camera is started, the interfered amplitude of some frequency bands is up to 20dB, and the interfered amplitude of all the frequency bands can not be improved to be within an acceptable range through circuit filtering and camera driving modification. In consideration of the situation that the front camera is turned on, the disturbed amplitude is too large, which brings poor user experience, and even serious faults such as the fact that a voice call cannot be connected may be caused.
Although the interference of the front-facing camera mainly affects the diversity antenna, since the main set antenna and the diversity antenna are normally turned on at the same time, when the diversity antenna is severely interfered, the effect is brought to the receiving performance of the whole mobile terminal, that is, the interference of the diversity antenna also affects the main set antenna, which seriously affects the user experience.

The main set antenna is responsible for sending and receiving radio frequency signals; the diversity antenna is responsible for receiving signals but not transmitting signals, and the base station combines the signals received from the two interfaces, so as to obtain diversity gain.
In the default state, a main set antenna and a diversity antenna in the mobile terminal are both in a normal open working state, and in the using process of the mobile terminal, the mobile terminal can detect the signal intensity when the first antenna receives signals and the signal intensity when the second antenna receives signals in real time, so that the first antenna is ensured to be always normally used, and if the wireless signals are connected, the received signals of the first antenna cannot be detected, and an error alarm is sent out.

Namely, the mobile terminal can determine the frequency band corresponding to the receiving sensitivity reduction range and the started functional component by inquiring the component interference query table.

And 102, judging whether an implementation condition is met or not according to the descending amplitude of the receiving sensitivity, and if so, switching the first antenna and the second antenna.
Specifically, the implementation conditions include: the receiving sensitivity descending amplitude of the second antenna is larger than a preset amplitude threshold value;
the step 102 includes:
after determining the descending amplitude of the receiving sensitivity of the second antenna, the mobile terminal judges whether the descending amplitude of the receiving sensitivity is larger than a preset amplitude threshold value;
when the receiving sensitivity descending amplitude is determined to be larger than a preset amplitude threshold value, the implementation condition is met, the mobile terminal closes the second antenna, and the first antenna is kept to be normally used;
and when the receiving sensitivity descending amplitude is determined to be less than or equal to a preset amplitude threshold value, the implementation condition is not met, and the first antenna and the second antenna are kept in normal use.
Fig. 3 is a flowchart illustrating a second method for adjusting antenna switching according to an embodiment of the present invention; as shown in fig. 3, the method includes:
here, step 301 and step 302 are the same as step 101 and step 102 shown in fig. 1, and are not described again here.
and when at least one of the frequency range of the wireless signal and the started functional component is determined to be out of work, the second antenna is turned on, and the first antenna is kept in normal use.
Specifically, when the mobile terminal detects that the frequency band of the wireless signal corresponding to the reception sensitivity reduction of the second antenna does not work any more, that is, the wireless signal of the frequency band is not connected any more, and/or the started functional component does not work any more, the second antenna is turned on again, and the first antenna is kept in normal use, so that the first antenna and the second antenna of the mobile terminal are turned on to work normally.
For the above method, the following are exemplified:
the component interference look-up table stores a corresponding relationship between a main camera and a frequency Band5, and indicates that when the main camera of the mobile terminal is enabled, severe interference is generated on the receiving sensitivity of a second antenna, namely a diversity antenna, of the LTE (Long Term Evolution ) Band5 (a Band available frequency Band, for example, the china unicom LTE is mainly Band3, and the china telecom LTE is mainly Band 1) of the mobile terminal.
Assuming that the implementation conditions are such that the set amplitude threshold K is exceeded and K is 10dB, the functional component is called a, i.e., the main camera, and the frequency Band of the wireless system is called B, i.e., Band5, there are the following scenarios:
firstly, the method comprises the following steps: when the functional component A and the frequency band B work simultaneously, the receiving sensitivity reduction amplitude is set as Ki, and the Ki is assumed to be about 20 dB;
when the mobile terminal detects that Ki is larger than K, the implementation condition is met, the implementation is started, the mobile terminal closes the second antenna, and meanwhile, the first antenna still keeps normal use;
and when the mobile terminal detects that any one or both of the functional component A and the frequency band B which work simultaneously do not work any more, the second antenna is restarted, so that the second antenna and the first antenna are normally superposed for use.
Secondly, the method comprises the following steps: and when the functional component A and the frequency band B work simultaneously, if Ki is less than or equal to K, the implementation condition is not met, the mobile terminal does not perform implementation action, and the first antenna and the second antenna are kept in normal superposition use.
Thirdly, the method comprises the following steps: when the functional component A and the frequency band B do not work simultaneously, the implementation is not started, and the first antenna and the second antenna are kept in normal superposed use.
The idea of the method of an embodiment of the present invention is explained below with reference to the above embodiments.
When a mobile terminal starts a certain component function application, the receiving sensitivity disturbed degree of different frequency bands under different wireless systems is detected by a known means and recorded and stored in a state pool of the terminal, and a threshold value K is set; when the recorded receiving sensitivity disturbed degree is detected and the receiving sensitivity reduced amplitude is expressed, and exceeds the threshold value K, the receiving signal quality is seriously damaged, and the user experience is influenced. By the method, when a user starts certain component function applications of the mobile terminal to cause the received signal to drop sharply, the mobile terminal can still keep normal communication; this effect is prevented from being carried over to the whole mobile terminal when the diversity antenna is severely interfered with.

and then, the mobile terminal continuously detects whether at least one of the frequency band B of the wireless signal corresponding to the reception sensitivity reduction amplitude and the started functional component A does not work any more, and when any one or both of the functional component A and the frequency band B which work simultaneously are detected to do not work any more, the second antenna is restarted, so that the second antenna and the first antenna are normally overlapped for use.
