Description

Terminal antenna adjusting method and device

Technical field

The present invention relates to the field of communication terminal technologies, and in particular, to a terminal antenna adjustment method and apparatus.

Background technique

When a user holds a wireless terminal (for example, a mobile phone or a tablet) to communicate, if the palm of the hand blocks the antenna of the mobile phone/tablet, the performance of the antenna is lowered, and the radiation at the location affects the user's health. Therefore, it is generally possible to reduce the transmission (transmitting) power of the position-holding antenna, thereby reducing the influence of the SAR (Specific Absorption Rate).

In the prior art, there are two main ways to reduce SAR on a wireless terminal:

In one implementation, the SAR is reduced according to a change in the RSSI (Received Signal Strength Indication) value of the wireless terminal antenna. The RSSI represents the magnitude of the signal strength of the base station received by the wireless terminal. When the human body is close to the main antenna or the diversity antenna on the wireless terminal, the RSSI value of the main antenna or the diversity antenna is lowered. When the user is holding the mobile phone or tablet to access the Internet, the transmission power of the main antenna or the diversity antenna is automatically adjusted by obtaining the change of the RSSI value of the mobile phone or the tablet, thereby adjusting the antenna performance and reducing the impact of the overall wireless SAR. However, in this implementation manner, it takes a long time to obtain the change of the RSSI value of the wireless terminal, and generally takes about 10s, and the real-time performance is poor.

In another implementation, a SAR Sensor is provided on the wireless terminal. Specifically, the antenna of the SAR Sensor is disposed near the 2G/3G/4G antenna or the WIFI antenna on the wireless terminal. When the human body is close to the antenna of the SAR Sensor, the capacitance change is caused, and the capacitive sensing is converted into a digital signal and transmitted. To the AP (Application Processor) chip on the wireless terminal, the AP chip control modem reduces the transmission and transmission power of the 3G antenna or the WIFI antenna on the wireless terminal, thereby reducing the overall wireless SAR. However, in this solution, since the SAR Sensor needs to be added in the wireless terminal, the structure design of the wireless terminal needs to reserve space for the SAR Sensor, thereby increasing the difficulty of designing the whole architecture and increasing the cost of the whole wireless terminal. .

detailed description

The above-mentioned objects, features, and advantages of the embodiments of the present invention will become more apparent and understood. Give further details.

As shown in FIG. 1 , an embodiment of a method for adjusting a terminal antenna provided by the present invention may include the following steps:

Step 101: Determine a manner in which the terminal is held; the manner of being held includes at least one of being held by the left hand and held by the right hand.

In the embodiment of the present application, the terminal antenna adjustment method may be applied to the terminal device. Specifically, the terminal device may include: a communication device such as a mobile phone or a tablet computer.

Usually, when a user uses a terminal, the terminal needs to be held. When holding the terminal, the user may hold the terminal with a single left hand, or may hold the terminal with a single right hand, or hold the terminal simultaneously with the right and left hands.

When the user holds the terminal, it may happen that the hand is close to the terminal antenna. If the current user's hand is close to the terminal antenna, in order to reduce the impact of the overall wireless SAR, the antenna transmission power at the close position of the opponent needs to be adjusted. Therefore, before adjusting the transmission power of the corresponding antenna, it is necessary to first determine the manner in which the terminal is held.

Step 102: Determine an antenna to be adjusted according to the manner of being held.

In the above step 102, after determining the manner in which the terminal is held, the antenna to be adjusted may be further determined according to the manner of being held.

Specifically, after determining the manner in which the terminal is held, it can be determined whether the hand that the user currently holds the terminal is close to the antenna in the terminal. When it is determined that the hand of the user currently holding the terminal is close to the antenna in the terminal, the antenna is determined to be an antenna to be adjusted, and the transmission power of the antenna to be adjusted needs to be adjusted.

Step 103: Decrease the transmission power of the antenna to be adjusted according to the first preset rule.

In step 103, in order to reduce the SAR impact, after determining that the terminal is to be adjusted, the transmission power of the antenna to be adjusted needs to be reduced.

Specifically, the rule for reducing the transmission power of the antenna to be adjusted may be preset. In the embodiment of the present invention, the preset rule is referred to as a “first preset rule”. The transmission power reduction method may be different for different terminal antennas. Therefore, for different antennas to be adjusted, it is necessary to reduce the transmission power of the corresponding antenna according to a preset rule.

In the embodiment of the present invention, the specific content of the first preset rule is not specifically limited.

In order to facilitate the understanding of the technical solution of the present invention, the specific implementation process of the above terminal antenna adjustment is described in detail through a specific implementation manner.

In the embodiment of the present invention, the TP (Touch Panel) measurement technology is specifically used to determine the manner in which the terminal is held.

In the embodiment of the present invention, as shown in FIG. 2, the foregoing implementation process of determining the manner in which the terminal is held includes the following steps:

Step 201: Detect a coordinate of a touch point of the user on the TP of the terminal, where the touch point is a touch point other than the touch function key;

Step 202: Determine the manner of being held according to the coordinates of the touched point.

In the above implementation manner, the touch function key is a touch control button with a function jump appearing on the terminal display screen, for example, a menu key set on the terminal display screen, a home button, and the like. In the embodiment of the present invention, the touch point mentioned refers to a touch point on the TP other than the touch function key. When the terminal detects that there is a touch point on the current TP, it can determine the manner of being held according to the coordinates of the touch point.

Specifically, in an embodiment of the present invention, the implementation process is as shown in FIG. 3. According to the coordinates of the touched point, the implementation process of determining the manner of being held may include the following steps:

Step 301: Determine a running track of the touch point according to coordinates of the touch point;

Step 302: Determine, according to the running trajectory of the touch point, the manner of being held.

Since different hands perform a touch operation on the terminal TP, the touch point running trajectory on the TP will be different. Usually, the TP display area of the mobile phone will be divided into a field shape as shown in FIG. When the user holds the mobile phone and uses the finger to operate the mobile phone on the TP, the touch point running trajectory on the TP is determined according to the position coordinate on the TP reported by the TP in the unit time, as shown in FIG. 5, thereby running according to the touch point. The trajectory, combined with the usual user gesture operation habits, determines whether the current user is holding with the left hand or the right hand.

In addition, in another embodiment of the present invention, the implementation process of determining the manner in which the terminal is held is as shown in FIG. 6, and may include the following steps:

Step 601: Acquire a position coordinate of the touch point, where the position coordinate includes: a longitudinal position coordinate and a lateral position coordinate;

Step 602: Obtain a maximum value and a minimum value of the longitudinal position coordinates and a maximum value and a minimum value of the lateral position coordinates;

Step 603: Determine a deflection direction of the pressing area according to the maximum value and the minimum value of the longitudinal position coordinates and the maximum value and the minimum value of the lateral position coordinates;

Step 604: Determine the manner of being held according to the direction of the bias of the pressing area.

In this implementation manner, when the finger of the user is pressed on the terminal TP, the TP acquires the position coordinates of the finger and the TP touch point, and at the same time, the TP acquires the maximum value and the minimum value of the vertical position coordinate in the pressing area corresponding to the touch point and the horizontal direction. The maximum and minimum values of the position coordinates. Generally, the pressing area is an elliptical area, and the deflection direction of the pressing area can be determined according to the maximum value and the minimum value of the longitudinal position coordinates and the maximum value and the minimum value of the lateral position coordinates in the pressing area corresponding to the touch point acquired by the TP. . Specifically, when the lateral coordinate of the position coordinate having the maximum value of the longitudinal position coordinate is greater than the lateral coordinate of the position coordinate having the minimum value of the longitudinal position coordinate, the left hand is held, and the pressing area is an elliptical area inclined to the right; otherwise, Hold for the right hand, the pressing area is an elliptical area that is inclined to the left. For example, the pressing area of the user's finger determined on the TP is as shown in FIG. 7. The horizontal coordinate of the position coordinate A having the maximum value of the longitudinal position coordinate is larger than the horizontal coordinate of the position coordinate B having the minimum value of the longitudinal position coordinate, and the current coordinate can be determined. Holding for the left hand; when the pressing area of the user's finger determined on the TP is as shown in FIG. 8, the horizontal coordinate of the position coordinate A having the maximum value of the longitudinal position coordinate is smaller than the horizontal coordinate of the position coordinate B having the minimum value of the longitudinal position coordinate, You can then determine that you are currently holding your right hand.

In the actual application scenario, when the user holds the terminal, the user may hold the left hand or the right hand. When the different hands are held, the holding position of the terminal will be different. In addition, when the user holds the terminal, the terminal's TP may be a horizontal screen display or a vertical screen display. In different display modes, the terminal's held position will also be different. Thus, in another embodiment provided by the present invention, the current grip of the terminal can be further combined. The holding mode and the display mode of the terminal screen determine the position to be held on the terminal, thereby determining the antenna to be adjusted according to the position where the terminal is held. In this embodiment, as shown in FIG. 9, the implementation process of the terminal antenna adjustment method may include:

Step 901: Determine a manner in which the terminal is held; the manner of being held includes: at least one of being held by the left hand and held by the right hand;

Step 902: Determine a screen display manner of the terminal, where the screen display manner includes: a horizontal screen display mode or a vertical screen display mode;

Step 903: Determine, according to the manner of being held and the manner of displaying the screen, the position of the terminal being held;

Step 904: Determine an antenna to be adjusted according to the position to be grasped;

Step 905: Decrease the transmission power of the antenna to be adjusted according to the first preset rule.

Taking a mobile phone as an example, for a mobile phone, the mobile phone can automatically determine whether the current display is a horizontal screen or a vertical screen. Therefore, according to the actual holding manner and the display manner of the mobile phone, the position that is currently held on the mobile phone can be determined. For example, as shown in FIG. 10, when the mobile phone is displayed in the vertical screen, and the current user is holding the left hand, it can be determined that the left hand grasps the position of holding the mobile phone. When the built-in antenna of the mobile phone is as shown in FIG. 9, it can be determined that the current holding position of the palm of the left hand is close to the diversity antenna disposed at the bottom of the mobile phone.

After determining the position at which the terminal is held, the antenna to be adjusted can be determined according to the position at which the terminal is held. In the embodiment of the present invention, the implementation process is as shown in FIG. 11 , and specifically includes the following steps:

Step 1101: Query a preset corresponding relation database, and pre-store the corresponding relationship between the held position and the antenna in the corresponding relation database;

Step 1102: Determine an antenna corresponding to the position to be held as an antenna to be adjusted.

In a specific application scenario, the habits of different users to hold the terminal may be collected in advance, and the corresponding relationship between the different positions held by the terminal and the terminal antenna is collected in each custom mode. In order to facilitate the terminal to determine the antenna to be adjusted at the holding position, a correspondence database may be established in the terminal system, and the corresponding relationship between the different positions held by the terminal and the terminal antenna is pre-stored through the correspondence database. After determining the location where the terminal is held, the corresponding relationship database may be queried to determine whether there is a correspondence between the location where the current terminal is held and the terminal antenna in the corresponding relation database, and if the current terminal is held, The corresponding position of the position and the terminal antenna can determine the antenna corresponding to the position to be held as the antenna to be adjusted.

In order to further improve the accuracy of the adjustment of the terminal antenna, the adjustment to be adjusted may be reduced according to the first preset rule. After the transmission power of the antenna, the RSSI value of the terminal is continuously detected. And detecting whether the reduced value of the RSSI value of the wireless terminal exceeds a preset lowering threshold; if the reduced value of the RSSI exceeds the lowering threshold, increasing the transmission power of the antenna to be adjusted according to the second preset rule.

In the above implementation manner, when the lowering threshold of the RSSI value is detected, when the lowering of the RSSI value exceeds the lowering threshold, it indicates that the previous operation for reducing the transmission power of the antenna to be adjusted is not suitable, and the transmission power of the antenna to be adjusted needs to be improved. The rule that increases the transmission power is referred to as the "second preset rule." In the embodiment of the present invention, the actual content of the second preset rule is not specifically limited, and related settings may be performed according to the actual application scenario.

Generally, the antenna built in the terminal can be divided into a main antenna and a sub-antenna. When the antenna to be adjusted is the main antenna and the terminal further includes the sub-antenna, the antenna to be adjusted needs to be switched to the sub-antenna, and the sub-antenna is switched to the main antenna. Through the function switching of the antenna, the performance of the antenna is ensured under the premise of effectively reducing the efficiency of the SAR, and the communication of the terminal is prevented from being affected due to the occlusion of the main antenna.

Corresponding to the foregoing method for adjusting a terminal antenna, the present invention provides a terminal antenna adjusting device, which can be disposed on a terminal.

As shown in FIG. 12, an embodiment of a terminal antenna adjusting device provided by the present invention may specifically include:

The held manner determining module 1201 is configured to determine a manner in which the terminal is held; the manner of being held includes: at least one of being held by the left hand and held by the right hand;

The first to be adjusted antenna determining module 1202 is configured to determine an antenna to be adjusted according to the manner of being held;

The antenna power adjustment module 1203 is configured to reduce the transmission power of the antenna to be adjusted according to the first preset rule.

In the embodiment of the present invention, when the user uses the terminal, the terminal needs to be held. When holding the terminal, the user may hold the terminal with a single left hand, or may hold the terminal with a single right hand, or hold the terminal simultaneously with the right and left hands.

When the user holds the terminal, it may happen that the hand is close to the terminal antenna. If the current user's hand is close to the terminal antenna, in order to reduce the impact of the overall wireless SAR, the antenna transmission power at the close position of the opponent needs to be adjusted. Therefore, before adjusting the transmission power of the corresponding antenna, it is necessary to first determine the manner in which the terminal is held by the held mode determining module. After determining the manner in which the terminal is held, the first to-be-adjusted antenna determining module determines whether the user currently holding the terminal is close to the antenna in the terminal. When it is determined that the user currently holding the terminal is close to the antenna in the terminal, the antenna is determined as the antenna to be adjusted, and the transmission power of the antenna to be adjusted Need to be adjusted. In order to reduce the SAR impact, after determining that the terminal is to be adjusted, the antenna power adjustment module is required to reduce the transmission power of the antenna to be adjusted. Specifically, the rule for reducing the transmission power of the antenna to be adjusted may be preset. In the embodiment of the present invention, the preset rule is referred to as a “first preset rule”. The transmission power reduction method may be different for different terminal antennas. Therefore, for different antennas to be adjusted, it is necessary to reduce the transmission power of the corresponding antenna according to a preset rule.

In an embodiment of the present invention, as shown in FIG. 13, the specific implementation manner of the foregoing hold mode determining module may include:

The coordinate detecting unit 1301 is configured to detect coordinates of a touch point of the user on the touch screen TP of the terminal, where the touch point is a touch point other than the touch function key;

The held manner determining unit 1302 is configured to determine the manner of being held according to the coordinates of the touched point.

In the actual application scenario, when the user holds the terminal, the user may hold the left hand or the right hand. When the different hands are held, the blocking position of the terminal will be different. In addition, when the user holds the terminal, the TP of the terminal may be a horizontal screen display or a vertical screen display. In different display modes, the user's holding position will also block the terminal. Therefore, the position that is held on the terminal is determined, and finally the current holding manner and display mode of the terminal need to be combined.

As shown in FIG. 14, the held mode determining unit may specifically include:

a running track determining subunit 1401, configured to determine a running track of the touch point according to coordinates of the touch point;

The first result subunit 1402 is configured to determine the manner of being held according to the running trajectory of the touch point.

In this implementation manner, since different hands perform a touch operation on the terminal TP, the touch point running trajectory on the TP will be different. When the user holds the mobile phone and uses the finger to operate the mobile phone on the TP, according to the position coordinate sequence on the TP reported by the TP in the unit time, the touch point running trajectory on the TP can be determined according to the current position coordinate sequence, thereby Touch the point trajectory, combined with the usual user gestures, to determine whether the current user is holding with the left hand or the right hand.

In another embodiment of the present invention, as shown in FIG. 15 , another implementation manner of the foregoing held manner determining unit may specifically include:

a region deflecting direction determining sub-unit 1503, configured to determine a biasing direction of the pressing region according to a maximum value and a minimum value of the longitudinal position coordinates and a maximum value and a minimum value of the lateral position coordinates;

The second result unit 1504 is configured to determine the manner of being held according to the direction of the bias of the pressing area.

In this implementation manner, when the finger of the user is pressed on the terminal TP, the TP acquires the position coordinates of the finger and the TP touch point, and at the same time, the TP acquires the maximum value and the minimum value of the vertical position coordinate in the pressing area corresponding to the touch point and the horizontal direction. The maximum and minimum values of the position coordinates. Generally, the pressing area is an elliptical area, and the deflection direction of the pressing area can be determined according to the maximum value and the minimum value of the longitudinal position coordinates and the maximum value and the minimum value of the lateral position coordinates in the pressing area corresponding to the touch point acquired by the TP. . Specifically, when the lateral coordinate of the position coordinate having the maximum value of the longitudinal position coordinate is greater than the lateral coordinate of the position coordinate having the minimum value of the longitudinal position coordinate, the left hand is held, and the pressing area is an elliptical area inclined to the right; otherwise, Hold for the right hand, the pressing area is an elliptical area that is inclined to the left.

In another embodiment of the terminal antenna adjusting device provided by the present invention, as shown in FIG. 16, the method further includes:

The screen display mode determining module 1601 is configured to determine a screen display manner of the terminal, and the screen display manner includes: a horizontal screen display mode or a vertical screen display mode;
