Description

A method and mobile terminal for reducing call interference

technical field

The embodiments of the present invention relate to the communication field, and in particular, to a method for reducing call interference and a mobile terminal.

Background technique

With the gradual popularization of mobile terminals, fast charging technology has emerged as the times require. The fast charging technology can enable the mobile terminal to complete charging in a short time, which solves the problem of insufficient battery life of the mobile terminal.

The fast charging technology usually controls the output power of the charging current according to the power of the battery of the mobile terminal. For example, the lower the power, the greater the output power of the charging current. Optimally, when the charging current is kept at the rated maximum output power, The charging speed is the fastest, resulting in fast charging.

However, the charging current will also cause different degrees of interference to the receiving performance of the mobile terminal. For example, when the mobile terminal implements a call function, it will transmit a signal to the base station, and the base station will also transmit a signal to the mobile terminal to complete the communication between the mobile terminal and the base station. Especially in some remote areas and other extreme conditions, the communication signal between the mobile terminal and the base station itself is relatively weak. If the mobile terminal is still in the charging state at this time, the charging current will interfere with the receiving performance of the mobile terminal. It will be more obvious, thereby greatly reducing the receiving sensitivity of the mobile terminal. After the user connects to the phone, there will be poor call quality and disconnection, which will cause call interference and bring inconvenience to the user.

The signal strength threshold is a critical value. When the signal receiving strength is at this critical value, the charging current will just not cause too much interference to the signal receiving strength of the channel corresponding to the current communication frequency band (here it is regarded as no interference), that is, it will not Interference with the receiving performance of the mobile terminal, so that according to the preset signal strength threshold, the current signal receiving strength can be divided into different ranges. When the current signal receiving strength is in a better range, it means that the mobile terminal is in The communication signal in the area is strong, and the interference caused by the charging current to the receiving performance of the mobile terminal is small, then the influence of the charging current on the receiving performance of the mobile terminal can be ignored; if the current signal receiving strength is in a poor range , indicating that the communication signal in the area where the mobile terminal is located is weak, and the charging current will cause greater interference to the receiving performance of the mobile terminal, then the power of the charging current can be adjusted to reduce the impact of the charging current on the receiving performance of the mobile terminal.

Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Embodiment one

Fig. 1 is a flowchart of a method for reducing call interference according to an embodiment of the present invention. The method for reducing call interference shown in Figure 1 is applied to a mobile terminal, and the method is applicable to a mobile terminal in a charging state, and the method includes:

Step S1: If it is detected that the mobile terminal has an incoming call, then detect the signal reception strength of the channel corresponding to the current communication frequency band.

In this step, if there is an incoming call, first detect the signal reception strength of the channel corresponding to the communication frequency band to determine the strength of the communication signal in the area where the mobile terminal is located. If the communication signal is strong, the charging current can be ignored. The interference caused by the receiving performance of the mobile terminal, if the communication signal is weak, the interference caused by the charging current to the receiving performance of the mobile terminal needs to be considered.

Step S2: Comparing the received signal strength with a preset signal strength threshold.

Wherein, the preset signal strength threshold is a threshold of the signal receiving strength, and when the signal receiving strength is equal to the preset signal strength threshold, it is just not disturbed by the charging current.

In this step, when the signal receiving strength is in a critical state, the interference caused by the charging current to the receiving performance of the mobile terminal is negligible, that is, the charging current just does not interfere with the signal receiving strength of the channel corresponding to the communication frequency band. The signal receiving strength corresponding to the state is the preset signal strength threshold, which is preset. The setting of the preset signal strength threshold can be obtained through research and data summarization of multiple experiments to ensure the preset signal strength. Objectivity and accuracy of intensity thresholding.

Step S3: adjusting the charging power of the mobile terminal according to the comparison result of the received signal strength and the preset signal strength threshold.

By comparing and determining whether the signal reception strength of the channel corresponding to the communication frequency band will be affected by the charging current, the power of the charging current of the mobile terminal is further adjusted according to the specific situation.

In the method for reducing call interference in this embodiment, the strength of the signal in the current area can be judged by detecting the signal reception strength of the channel corresponding to the current communication frequency band, so that it can be judged whether the area where the mobile terminal is located is under extreme conditions In the area, when the area where the mobile terminal is located is an area with extreme conditions, adjust the power of the charging current to reduce the interference of the charging current on the receiving performance of the mobile terminal, reduce call interference, improve call quality, and avoid disconnection, etc. , thereby solving the problem that the charging current interferes with the receiving performance of the mobile terminal, thereby causing call interference.

Preferably, if no incoming call is detected, the mobile terminal is kept charged with the power of the rated charging current to maintain a normal charging state.

Further, when the signal reception strength of the channel corresponding to the communication frequency band is greater than or equal to the preset signal strength threshold, it means that the signal reception strength of the channel corresponding to the communication frequency band is within a strong signal range, and the communication signal is strong. It will not cause interference to the receiving performance of the mobile terminal, and the call quality can be guaranteed. Therefore, on the basis of FIG. 1, referring to FIG. 2, step S3 may include:

Step S31: When the received signal strength is greater than or equal to a preset signal strength threshold, maintain the charging power of the mobile terminal.

In this step, if the signal receiving strength of the channel corresponding to the communication frequency band is greater than or equal to the preset preset signal strength threshold, it means that the mobile terminal is in a strong signal state, and the mobile terminal has a large margin in receiving performance at this time, even if it is charged Under the influence of the current, better receiving performance can still be maintained. At this time, the charging power of the mobile terminal can be maintained. Preferably, the charging power of the mobile terminal can be maintained at the maximum output power, without considering the influence of the charging current on the radio frequency receiving performance .

When the signal reception strength of the channel corresponding to the communication frequency band is lower than the preset signal strength threshold, it means that the signal reception strength of the channel corresponding to the communication frequency band is within a weak signal range, and the communication signal in this area is weak. Although the phone can be connected, the charging current Certain interference will be caused to the receiving performance of the mobile terminal, thereby causing the call to be interfered, the call quality to be poor, and even problems such as call disconnection to occur. Therefore, continuing to refer to FIG. 2, step S3 may also include:

Step S32: When the received signal strength is lower than the preset signal strength threshold, reduce the charging power of the mobile terminal.

In this step, if the signal reception strength of the channel corresponding to the communication frequency band is less than the preset preset signal strength threshold, it indicates that the mobile terminal is in a weak signal state. At this time, the mobile terminal has poor reception performance and is easily affected by other interference. Consider reducing charging power to reduce interference to RF reception. Therefore, after the adjustment in this step, the charging power is reduced, the current is reduced, and the interference to the receiving performance of the mobile terminal is correspondingly reduced, thereby reducing call interference and improving call quality.

Further, on the basis of FIG. 2 , referring to FIG. 3 , when the received signal strength is less than the preset signal strength threshold, step S32 may include:

Step S321: reducing the charging power of the mobile terminal, so that the charging power of the mobile terminal per unit time is greater than or equal to the total power consumption of the mobile terminal per unit time.

In the method for reducing call interference shown in Figure 3, before adjusting the charging power, it is also necessary to detect the total power consumption of the mobile terminal per unit time, so as to reduce the charging power while at least ensuring the charging of the mobile terminal per unit time The power is in the same state as the total power consumption per unit time of the mobile terminal. More preferably, there is still a certain margin for the charging power, that is, the charging power of the mobile terminal per unit time is greater than that of the mobile terminal per unit time. The total power consumption ensures that the battery life of the mobile terminal is guaranteed in the call scene.

Further, the total power consumption of the mobile terminal comes from multiple aspects, therefore, on the basis of Figure 3, referring to Figure 4, the way to obtain the total power consumption of the mobile terminal per unit time includes:

Step S322: Detect the power consumption per unit time of the radio frequency module and other functional modules when the mobile terminal is talking.

Step S323: Calculate the total power consumption of the mobile terminal per unit time according to the power consumption per unit time of the radio frequency module and other functional modules when the mobile terminal is talking.

In the method in FIG. 4 , the radio frequency power consumption generated by the call is detected, that is, the power consumption of the radio frequency module, and the power consumption of functions of other modules of the mobile terminal is detected, that is, the power consumption of other functional modules. For example, in the call state, the mobile terminal is in the state of screen off or on, earphone or hands-free, etc. The modules involved in the mobile terminal are different, and the corresponding functions are also different. Therefore, the power consumption of each module Therefore, the power consumption in different call scenarios is different. The mobile terminal needs to obtain the usage status of each module during the call in real time, and then the power consumption of each module can be obtained. The total power consumption of the time.

It should be noted that what is shown in FIG. 5 is a structural block diagram of a mobile terminal, including a processing module 501 and a radio frequency module 502 , and the radio frequency module 502 further includes a radio frequency front-end part 5021 and a radio frequency receiver 5022 . Among them, the RF front-end part 5021 has power amplifiers, duplexers, filters, switch modules and other devices. During the communication process between the mobile terminal and the base station, the power amplifier can amplify the channel to the specified power to maintain normal communication with the base station. Communication, the transmission power of the power amplifier is controlled by the base station so that the base station receives the desired signal strength and signal quality. After the radio frequency front-end part 5021 receives the signal sent by the base station, it transmits the signal to the radio frequency transceiver 5022 for processing; radio frequency The transceiver 5022 is responsible for modulating baseband signals, demodulating radio frequency signals, and performing signal conversion processing. The processing module 501 may be a processor, the processor is connected to the radio frequency transceiver 5022, and the processor is responsible for processing baseband signals.

For the power consumption detection of the radio frequency module, it can be realized by using the radio frequency module 502 in the mobile terminal. For reference, the steps of power consumption detection of the radio frequency module may include:

The radio frequency front-end part 5021 amplifies the power of the channel corresponding to the current communication frequency band;

According to the detected amplification power, the power consumption of the radio frequency module in unit time is obtained.

In this step, preferably, the processor of the mobile terminal can obtain the power transmitted by the current power amplifier through the radio frequency module 502, that is, determine the transmission power of the current power amplifier. Different transmission powers correspond to different power consumption. By determining The current transmit power can calculate the current radio frequency power consumption of the terminal, that is, the power consumption of the radio frequency module.

For reference, referring to Fig. 6, on the basis of any one of Fig. 1 to Fig. 4, step S1 may include:

Step S11: Amplify the first radio frequency power of the channel corresponding to the current communication frequency band, and send the first radio frequency power signal to the base station.

Amplify the first radio frequency power of the channel corresponding to the current communication frequency band to the specified power to ensure communication with the base station.

Step S12: receiving a second radio frequency power signal sent by the base station based on the first radio frequency power signal.

The base station and the mobile terminal communicate with each other, the base station sends a second radio frequency power signal to the mobile terminal based on the first radio frequency power signal sent by the mobile terminal, and the mobile terminal receives the second radio frequency power signal.

Step S13: Determine signal reception strength according to the second radio frequency power signal.

According to the magnitude of the second radio frequency power signal received by the mobile terminal, the current signal reception strength can be known. Wherein, the signal reception strength here is reflected by the magnitude of the radio frequency power signal.

In the method of FIG. 6, combined with the mobile terminal in FIG. 5, step S11 and step S12 can be performed by the radio frequency front-end part 5021, and the processor can obtain the signal reception strength of the channel corresponding to the communication frequency band through the radio frequency transceiver 5022, and the steps can be completed. S13. Wherein, the radio frequency transceiver 5022 can process the received second radio frequency power signal, and finally the processor can obtain the signal receiving strength according to the processed second radio frequency power signal.

Preferably, in order to help understand the method in this embodiment more deeply, FIG. 7 is a specific example enumerated according to the method in this embodiment. In this example, it includes:

Step S101: Detect whether there is an incoming call, if yes, go to step S102; if not, charge with rated power, go to step S107;

Step S102: Detect the signal reception quality of the current call frequency band;

Step S103: If the signal reception quality of the current call frequency band is detected, check whether the signal reception quality is lower than the preset signal strength threshold, if yes, proceed to step S104; if not, charge with rated power, and proceed to step S107;

Step S104: Determine the current transmission power, and determine the corresponding power consumption according to the power;

Step S105: Detect the power consumption of other modules, and determine the total power consumption of the terminal;

Step S106: Adjust the current charging current of the terminal so that it is not lower than the total power consumption of the terminal;

Step S107: Maintain the charging state, and return to step S101.

This example calculates the appropriate charging power by judging the signal reception quality of the mobile terminal in the current area and the total power consumption of the mobile terminal to reduce the interference of charging on calls and ensure charging. The level of signal reception under extreme conditions improves call quality.

In this example, the signal reception quality can be reflected by the signal reception strength.

Preferably, the signal reception strength can be reflected by the signal power received by the mobile terminal from the base station, so that the signal reception strength can be determined by taking the signal power received by the mobile terminal from the base station as a parameter. Wherein, the preset signal strength threshold is a signal power threshold received by a mobile terminal from the base station.
