Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The embodiment provides the setting methods and terminal of a kind of terminal antenna transmission power, solve terminal day
The transmission power of line is difficult to the problem of meeting user SAR and call performance simultaneously.
First embodiment
As shown in Figure 1, the embodiment provides a kind of setting methods of terminal antenna transmission power, comprising:
Step 101: it is on call in terminal, and user at a distance from terminal be less than pre-determined distance when, judge terminal
Whether the specific absorption rate SAR of antenna is greater than default SAR value.
When terminal is on call, the distance between user face and terminal can be detected by Proximity Sensor
Whether it is less than pre-determined distance, pre-determined distance is less than at a distance from Proximity Sensor detects user's head between terminal, i.e.,
When user's head is close to terminal, judge whether the SAR of terminal antenna is greater than default SAR value.
Specifically, when whether the SAR for judging terminal antenna is greater than default SAR value, it can be by judging that terminal antenna is current
Transmission power whether be greater than predetermined power threshold value, if the current transmission power of terminal antenna is greater than the predetermined power threshold value,
Judge that the SAR of terminal antenna is greater than default SAR value, otherwise, it is above-mentioned default to judge that the SAR of terminal antenna is less than or equal to
SAR value.
Step 102: if more than default SAR value, then in real time according to the volume value of terminal microphone input sound and default sound
The relationship for measuring threshold value carries out reduction processing to preconfigured transmission power, and will reduce that treated transmission power is set as
The transmission power of terminal antenna.
Specifically, obtaining the volume value of terminal microphone input sound in real time, and defeated according to the terminal microphone got
Enter the volume value of sound and the relationship of default volume threshold, reduction processing is carried out to preconfigured transmission power, and will reduce
Transmission power that treated is set as the transmission power of the terminal antenna.
In the embodiment of the present invention, the volume value of real-time monitoring terminal microphone input sound, and according to microphone input sound
The relationship of the volume value of sound and default volume threshold carries out reduction processing to preconfigured transmission power, reaches according to Mike
The volume value of wind input sound carries out reduction processing to preconfigured transmission power in real time, so that the transmission power symbol after reducing
Close current call demand.
Here default volume threshold may be configured as 0, i.e., is not zero in the volume value of terminal microphone current input sound
When, it determines that power de-rating values at this time are the first power de-rating values, otherwise determines power de-rating values at this time for the second power drop
Volume value, second power de-rating values are greater than the first power de-rating values, can guarantee terminal not when the second power de-rating values are arranged
It goes offline.
In addition, user is silent, but still has the case where other noises, above-mentioned default volume threshold in communication process
Value can not also be 0, can be configured according to user demand in setting.
Here, as long as detecting that the SAR of a certain antenna of terminal is greater than default SAR value, terminal antenna is entered by power shape
State, i.e., according to the relationship of the volume value of terminal microphone current input sound and default volume threshold, to preconfigured transmitting
Power carries out reduction processing.Here transmission power can be specially antenna total radiant power (Total Radiated Power,
TRP)。
It is smaller or to when there is no sound in microphone input sound in the embodiment of the present invention, antenna transmission power drop
More, when having voice input or sound is bigger, antenna transmission power drops few, or even does not drop, thus effectively
Ensure that microphone has input sound and communication effect when larger sound, and microphone voice is smaller or when not having sound, leads to
News effect difference will not cause very big influence to the call of user, combine SAR and communication effect.
The setting method of the terminal antenna transmission power of the embodiment of the present invention, it is on call in terminal, and user with
When the distance of the terminal is less than pre-determined distance, judge whether the specific absorption rate SAR of terminal antenna is greater than default SAR value；If big
In the default SAR value, then in real time according to the relationship of the volume value of terminal microphone input sound and default volume threshold, to pre-
The transmission power first configured carries out reduction processing, can be when the volume value of terminal microphone current input sound is larger, will be preparatory
The transmission power drop of configuration it is few, the volume value of terminal microphone current input sound it is smaller even without sound when,
Preconfigured transmission power is dropped it is more, guarantee terminal antenna SAR it is not exceeded under the premise of, guarantee the logical of terminal
Talk about performance.
Second embodiment
