Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to an antenna control method and a mobile terminal.
Background
With the extreme pursuit of the user for the use experience, the performance requirement of the user for the mobile terminal is higher and higher, and a plurality of antennas are often required to be arranged in the mobile terminal to improve the communication performance. In order to enable the antenna of the mobile terminal to still achieve better communication performance in various application scenarios, the antennas often need to be arranged at multiple positions of the mobile terminal.
In practical applications, a user tends to approach one or more antennas in a mobile terminal during the use of the mobile terminal. However, when the antenna close to the user is a transmitting antenna in the mobile terminal, the electromagnetic absorption rate (SAR) of the corresponding portion of the user is often too high, which may cause irreversible damage to the user.
in the prior art, in order to reduce the SAR value of a transmitting antenna of a mobile terminal, sensors such as an infrared sensor, a photosensitive sensor, a capacitor and the like are often required to be arranged in the mobile terminal. In the case that the sensor detects that the user is close to the sensor, the conducted power of the transmitting antenna at the corresponding position can be reduced so as to reduce the SAR value of the transmitting antenna. However, since one sensor can only detect whether a user approaches to one location, and antennas in the mobile terminal are often disposed at multiple locations, sensors are often disposed at multiple locations in the existing mobile terminal, which easily increases the cost of the mobile terminal. Moreover, since the sensor can only sense the approach of a user in a single direction, in order to improve the user safety, in the existing mobile terminal, the conduction power of the antenna is often required to be reduced under the condition that the approach of the user is not detected, so that the radiation performance of the antenna is reduced, and further, the use experience of the user is reduced.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Fig. 1 is a flowchart of an antenna control method provided in an embodiment of the present invention, and as shown in fig. 1, the method may be applied to a mobile terminal, where the mobile terminal may include multiple antennas, and the method may include:
Step 101: and acquiring the signal strength of each antenna in the mobile terminal.
In the embodiment of the present invention, the mobile terminal may include a plurality of antennas, and in order to enable the mobile terminal to still achieve better communication performance in a plurality of application scenarios, the plurality of antennas often need to be disposed at a plurality of positions of the mobile terminal. The plurality of antennas may include one transmitting antenna and at least one receiving antenna.
In practical applications, a signal detection module is often disposed in a mobile terminal, and the signal detection module may be configured to obtain signal strength of each antenna in the mobile terminal. Specifically, the signal detection module may include a plurality of single-pole multi-position switches, a plurality of filters, a power detector, and the like. In the embodiment of the present invention, after the mobile terminal registers in a network, the signal detection module may acquire the signal strength of each antenna in the mobile terminal.
For example, if the mobile terminal includes three antennas A, B, C, where antenna a is a transmitting antenna, and antennas B and C are receiving antennas, in step 101, the signal strength of antennas a, B and C may be obtained through the signal detection module.
step 102: and determining a signal strength difference value according to the signal strength of the transmitting antenna and the signal strength of at least one receiving antenna.
In the embodiment of the present invention, a signal strength difference may be determined according to the signal strength of the transmitting antenna and the signal strength of the at least one receiving antenna, so as to determine whether the user is approaching or touching the mobile terminal according to the signal strength difference. Specifically, the signal strength difference may be a difference obtained by subtracting the signal strength of the receiving antenna from the signal strength of the transmitting antenna.
for example, if antenna a is a transmitting antenna and antennas B and C are receiving antennas, then in step 102, the signal strength difference between antenna a and antenna B and the signal strength difference between antenna a and antenna C may be determined respectively.
in practical applications, each antenna in the mobile terminal is often a directional antenna, and for the transmitting antenna, the electromagnetic wave energy radiated by the transmitting antenna should be concentrated as much as possible in a specified transmitting direction, and not radiated or radiated very weakly in other directions. That is to say, when a user approaches or touches the mobile terminal from the designated emission direction of the emission antenna, the emission antenna may generate a large radiation to the user, and when the user approaches or touches the mobile terminal from another direction, the emission antenna may not generate a small radiation to the user.
In practical applications, when a user approaches or touches the mobile terminal from a designated transmitting direction of the transmitting antenna, the signal strength of the transmitting antenna is reduced, and thus, the signal strength difference between the transmitting antenna and the receiving antenna is reduced.
In the embodiment of the present invention, for each receiving antenna, a corresponding set threshold may be set. When the signal strength difference of the receiving antenna is smaller than the corresponding set threshold, it may be considered that the user approaches or touches the mobile terminal from the designated transmitting direction of the transmitting antenna.
specifically, the set threshold corresponding to the receiving antenna may be obtained by subtracting the signal strength of the receiving antenna from the signal strength of the transmitting antenna when the mobile terminal is in a free state. The free state may be a laboratory state in which the mobile terminal is not in the proximity or touch of a user.
it can be understood that, in the embodiment of the present invention, the number of the corresponding set thresholds may be determined according to the number of the receiving antennas.
Specifically, when the number of the receiving antennas is one, the number of the corresponding set thresholds is also one, and when the signal strength difference of the receiving antennas is smaller than the corresponding set threshold, it may be determined that the user approaches or touches the mobile terminal from the designated transmitting direction of the transmitting antenna.
For example, if the mobile terminal includes only two antennas, where the antenna a is a transmitting antenna and the antenna B is a receiving antenna, the set threshold may be Z1, and when the difference between the signal strengths of the antenna a and the antenna B is smaller than Z1, it may be considered that the user approaches or touches the mobile terminal from the designated transmitting direction of the antenna a.
Specifically, when the number of the receiving antennas is plural, each receiving antenna corresponds to one of the set thresholds, that is, the number of the set thresholds is equal to the number of the receiving antennas.
In practical applications, when the number of the receiving antennas is multiple, and the signal strength difference of any one of the receiving antennas is smaller than the corresponding set threshold, it may be determined that the user approaches or touches the mobile terminal from the designated transmitting direction of the transmitting antenna.
For example, if the mobile terminal includes the transmitting antenna a and the plurality of receiving antennas B, C, the set threshold corresponding to the antenna a and the antenna B may be Z1, and the set threshold corresponding to the antenna a and the antenna C may be Z2, when the difference between the signal strengths of the antenna a and the antenna B is smaller than Z1, or the difference between the signal strengths of the antenna a and the antenna C is smaller than Z2, it may be considered that the user approaches or touches the mobile terminal from the designated transmitting direction of the antenna a.
In the embodiment of the present invention, when the signal strength difference of each receiving antenna is greater than or equal to the corresponding set threshold, it may be determined that no user approaches or touches the mobile terminal from the designated transmitting direction of the transmitting antenna, and at this time, the SAR value of the currently used transmitting antenna does not need to be reduced.
Step 103: and when the signal intensity difference value meets a first preset condition, reducing the absorption ratio of the electromagnetic wave.
In the embodiment of the invention, whether a user approaches or touches the mobile terminal from the specified transmitting direction of the transmitting antenna can be judged through the signal intensity difference, and under the condition that the user approaches or touches the mobile terminal from the specified transmitting direction of the transmitting antenna, the transmitting antenna can be considered to possibly generate electromagnetic radiation damage to the user, and at the moment, SAR reduction operation can be executed to avoid the electromagnetic radiation damage to the user caused by the transmitting antenna.
in practical application, a first preset condition may be set, and whether a user approaches or touches the mobile terminal from the designated transmitting direction of the transmitting antenna may be determined by determining whether the signal strength difference satisfies the first preset condition.
Specifically, in a case that the number of the receiving antennas is one, the first preset condition may be that the signal strength difference of the receiving antennas is smaller than a corresponding set threshold. In a case that the number of the receiving antennas is multiple, the first preset condition may be that a signal strength difference of any one of the receiving antennas is smaller than a corresponding set threshold.
In the embodiment of the present invention, when the signal strength difference satisfies a first preset condition, it may be considered that a user approaches or touches the mobile terminal from a designated transmission direction of the transmitting antenna, and the transmitting antenna may cause electromagnetic radiation damage to the user. That is to say, in the embodiment of the present invention, it is avoided that a plurality of infrared, photosensitive, capacitive and other sensors are used in the mobile terminal to detect whether the user is approaching or touching the mobile terminal, so that the cost of the mobile terminal can be reduced, and the use experience of the user is improved.
to sum up, the antenna control method according to the embodiment of the present invention may at least include the following advantages:
in the antenna control method provided by the embodiment of the invention, the signal intensity of each antenna in the mobile terminal can be obtained, then the signal intensity difference value is determined according to the signal intensity of the transmitting antenna and the signal intensity of at least one receiving antenna, when the signal intensity difference value meets a first preset condition, a user can be considered to approach or touch the mobile terminal from the appointed transmitting direction of the transmitting antenna, the transmitting antenna can possibly generate electromagnetic radiation damage to the user, and at the moment, the electromagnetic wave absorption ratio can be reduced, so that the currently used transmitting antenna can be prevented from generating electromagnetic radiation damage to the user. That is to say, in the embodiment of the present invention, it is avoided that a plurality of infrared, photosensitive, capacitive and other sensors are used in the mobile terminal to detect whether the user is approaching or touching the mobile terminal, so that the cost of the mobile terminal can be reduced, and the use experience of the user is improved.
Example two
Fig. 2 is a second flowchart of an antenna control method according to an embodiment of the present invention, and as shown in fig. 2, the method may be applied to a mobile terminal, where the mobile terminal includes multiple antennas, and the method may include:
Step 201: and acquiring the signal strength of each antenna in the mobile terminal.
step 202: and determining a signal strength difference value according to the signal strength of the transmitting antenna and the signal strength of at least one receiving antenna.
step 203: and when the signal intensity difference value meets a first preset condition, reducing the absorption ratio of the electromagnetic wave.
in the embodiment of the present invention, when the signal strength difference satisfies a first preset condition, it may be considered that a user approaches or touches the mobile terminal from a designated transmission direction of the transmitting antenna, and the transmitting antenna may cause electromagnetic radiation damage to the user, and at this time, the SAR reduction operation may be performed to avoid electromagnetic radiation damage to the user caused by the currently used transmitting antenna.
Fig. 3 is a flowchart of a SAR reduction operation method according to an embodiment of the present invention, and as shown in fig. 2, the method may include:
step 2031: and reducing the conduction power of the transmitting antenna under the condition that the signal strength of the transmitting antenna is greater than or equal to a first preset value.
Specifically, the first preset value may be a minimum signal strength required by the transmitting antenna to meet the use requirements of the user such as conversation and downloading. In practical application, the first preset value can be specifically set according to the configuration requirement of the mobile terminal, and the specific value of the first preset value is not limited in the embodiment of the present invention.
In the embodiment of the present invention, when the signal strength of the transmitting antenna is greater than or equal to the first preset value, the signal strength of the transmitting antenna can be considered to meet the use requirements of a user such as conversation, downloading, and the like. At this time, the conducted power of the transmitting antenna can be reduced to reduce the electromagnetic radiation intensity of the transmitting antenna, so that the currently used transmitting antenna is prevented from generating electromagnetic radiation damage to a user by reducing the SAR value of the transmitting antenna on the premise that the use of the user is met in the transmitting sky.
step 2032: and under the condition that the signal strength of the transmitting antenna is smaller than the first preset value, selecting one of the receiving antennas to be switched to a new transmitting antenna.
In practical applications, when a user approaches or touches the mobile terminal from a designated transmitting direction of the transmitting antenna, the signal strength of the transmitting antenna is reduced. When the signal strength of the transmitting antenna is reduced to be less than the first preset value, the signal strength of the transmitting antenna can be considered to be unable to meet the use requirements of a user for conversation, downloading and the like, and at this time, the transmitting antenna can be switched to a new receiving antenna, and one of the receiving antennas can be selected to be switched to a new transmitting antenna. Therefore, by switching the new transmitting antenna, the appointed transmitting direction of the new transmitting antenna and the direction of the user approaching or touching the mobile terminal can be staggered, so that the influence of the user on the signal intensity of the new transmitting antenna can be avoided, the signal intensity of the new transmitting antenna can meet the use requirements of the user such as conversation and downloading, and the electromagnetic radiation damage of the new transmitting antenna to the user can be avoided.
In the embodiments of the present invention, when the number of the receiving antennas is different, there is also a difference in the specific operation of selecting one of the receiving antennas to switch to a new transmitting antenna.
When the number of the receiving antennas is one, the transmitting antenna may be switched to a new receiving antenna, and the receiving antenna may be switched to a new transmitting antenna.
When the number of the receiving antennas is multiple, one receiving antenna needs to be selected from the multiple receiving antennas and switched to a new transmitting antenna, and the specific operations are as follows:
firstly, under the condition that the signal intensity of the transmitting antenna is smaller than the first preset value, the signal intensity of each receiving antenna is compared.
then, the receiving antenna with the strongest signal strength is selected to be switched to a new transmitting antenna.
In the embodiment of the invention, under the condition that the number of the receiving antennas is multiple, one receiving antenna with the strongest signal intensity can be selected to be switched to a new transmitting antenna, so that the electromagnetic radiation damage to a user caused by the new transmitting antenna can be avoided, the signal intensity of the new transmitting antenna can be higher, and the use experience of the user in use operations such as conversation, downloading and the like can be improved to the maximum extent.
In summary, in step 203, when the signal strength difference satisfies a first preset condition, the signal value of the transmitting antenna may be compared with the first preset value. And under the condition that the signal intensity of the transmitting antenna is greater than or equal to a first preset value, the conducted power of the transmitting antenna can be reduced, so that the transmitting antenna is prevented from generating electromagnetic radiation damage to a user by reducing the SAR value of the transmitting antenna on the premise that the use of the user is met in the transmitting day. Under the condition that the signal intensity of the transmitting antenna is smaller than the first preset value, one of the receiving antennas can be selected to be switched to a new transmitting antenna, so that electromagnetic radiation damage to a user caused by the new transmitting antenna can be avoided, the signal intensity of the new transmitting antenna can be larger, and the use experience of use operations such as conversation, downloading and the like of the user can be improved to the maximum extent.
Step 204: and detecting the network residing state of the mobile terminal.
in practical application, the signal strength of each antenna in the mobile terminal may be detected according to a preset frequency, so as to obtain the signal strength of each antenna in the mobile terminal. Specifically, the preset frequency may be set according to an actual condition, and the larger the preset frequency is, the higher the accuracy of the antenna control method according to the embodiment of the present invention is, and the smaller the preset frequency is, the smaller the power consumption of the mobile terminal is. In practical applications, a person skilled in the art may set the specific frequency of the preset frequency according to actual needs, and the specific frequency of the preset frequency is not limited in the embodiment of the present invention.
in the embodiment of the present invention, after the step of reducing the electromagnetic wave absorption ratio, the network camping state of the mobile terminal may be detected. In practical applications, the network-resident state may be a network connection state of the mobile terminal, and the network-resident state may be a connection state or a disconnection state.
Step 205: and stopping detecting the signal strength of each antenna in the movement when the network-resident state is interrupted.
In the embodiment of the invention, when the network-resident state of the mobile terminal is interrupted, the mobile terminal does not need to use an antenna to transmit and receive signals, at the moment, a transmitting antenna in the mobile terminal does not generate electromagnetic radiation damage to a user, and under the condition, the detection of the signal intensity of each antenna in the mobile terminal can be stopped, so that the power consumption of the mobile terminal is reduced, and the purpose of saving energy is achieved.
To sum up, the antenna control method according to the embodiment of the present invention may at least include the following advantages:
first, in the antenna control method provided in the embodiment of the present invention, a signal strength difference may be determined by obtaining signal strengths of antennas in a mobile terminal, and then according to the signal strength of the transmitting antenna and the signal strength of at least one receiving antenna, when the signal strength difference satisfies a first preset condition, it may be considered that a user approaches or touches the mobile terminal from an assigned transmitting direction of the transmitting antenna, and the transmitting antenna may cause electromagnetic radiation damage to the user, and at this time, an electromagnetic wave absorption ratio may be reduced, so as to avoid the transmitting antenna from causing electromagnetic radiation damage to the user. That is to say, in the embodiment of the present invention, it is avoided that a plurality of infrared, photosensitive, capacitive and other sensors are used in the mobile terminal to detect whether the user is approaching or touching the mobile terminal, so that the cost of the mobile terminal can be reduced, and the use experience of the user is improved.
secondly, in the embodiment of the present invention, when the signal strength difference satisfies a first preset condition, the signal value of the transmitting antenna may be compared with the first preset value. And under the condition that the signal intensity of the transmitting antenna is greater than or equal to a first preset value, the conducted power of the transmitting antenna can be reduced, so that the transmitting antenna can avoid electromagnetic radiation damage to a user by reducing the SAR value of the transmitting antenna on the premise that the use of the transmitting antenna is met. Under the condition that the signal intensity of the transmitting antenna is smaller than the first preset value, one of the receiving antennas can be selected to be switched to a new transmitting antenna, so that electromagnetic radiation damage to a user caused by the new transmitting antenna can be avoided, the signal intensity of the new transmitting antenna can be larger, and the use experience of use operations such as conversation, downloading and the like of the user can be improved to the maximum extent.
In addition, in the embodiment of the present invention, when the network-resident state of the mobile terminal is an interruption, the mobile terminal does not need to use an antenna to transmit and receive signals, and at this time, a transmitting antenna in the mobile terminal does not cause electromagnetic radiation damage to a user.
