Abstract

Embodiments of the present invention disclose a method for controlling terminal signal transmission, and a terminal. A method for controlling terminal signal transmission includes: monitoring a current working mode of a terminal; transmitting a signal according to first transmit power if it is found through monitoring that the terminal is currently in a first working mode, and transmitting the signal according to second transmit power if it is found through monitoring that the terminal is currently in a second working mode, where the first transmit power is greater than the second transmit power. The technical solution of the embodiments of the present invention helps to enable the terminal to obtain as good radio reception and transmission performance as possible at a same radiation absorption index.

Claims

1. A method for controlling terminal signal transmission, comprising:

monitoring a current working mode of a terminal;

receiving, by the terminal, an instruction from a base station instructing the terminal to transmit at a specific transmit power level;

transmitting a signal according to a first transmit power, which is an enhanced transmit power that is greater by a first power threshold than the specific transmit power level at which the terminal was instructed to transmit by the base station, if it is found through monitoring that the terminal is currently in a first working mode; and

transmitting the signal according to a second transmit power if it is found through monitoring that the terminal is currently in a second working mode, wherein the first transmit power is greater than the second transmit power.

2. The method according to claim 1, wherein the first working mode is a working mode in which a user is still capable of using the terminal to perform a service normally when a distance between the terminal and the body of the user is at least a first distance threshold.

3. The method according to claim 1, wherein

the monitoring the current working mode of the terminal comprises:

if it is detected that the terminal performing a call service is connected to a headset or uses a handsfree function, or it is detected that the terminal only performs a data service currently, determining that the terminal is in the first working mode; and

if it is sensed through a light sensor that the terminal performing a call service is close to the body of the user, or it is sensed through a distance sensor that a distance between the terminal performing a call service and the body of the user is smaller than a first distance threshold, or it is detected that the terminal performing a call service does not use the headset or the handsfree function, determining that the terminal is in the second working mode.

4. The method according to claim 2, wherein

the transmitting the signal according to the first transmit power comprises:

searching a preset power table, preset in the terminal, according to the specific transmit power level at which the terminal was instructed to transmit by the base station, wherein

the power table records correspondence between transmit power levels and enhanced transmit powers, respectively, and

for each respective transmit power level, the corresponding enhanced transmit power is greater by the first power threshold than a standard transmit power corresponding to the respective transmit power level,

to thereby find, from the power table, an enhanced power corresponding to the specific transmit power level at which the terminal was instructed to transmit by the base station; and

transmitting the signal according to the found enhanced transmit power corresponding to the specific transmit power level at which the terminal was instructed to transmit by the base station.

5. The method according to claim 2, wherein

a value range of the first power threshold is 1 to 2 decibels.

6. The method according to claim 1, wherein the first working mode is one or more of the following working modes:

a working mode of making a call by using a headset, a working mode of making a call by using a handsfree function, and a data service transmission mode.

7. A non-transitory readable storage medium of a computing apparatus, wherein the storage medium stores a computer program, and the program is configured to instruct the computing apparatus to perform the method according to claim 1.

8. A terminal, comprising:

a monitoring module, configured to monitor a current working mode of the terminal; and

a power control module, configured to transmit a signal according to a first transmit power, which is an enhanced transmit power that is greater by a first power threshold than a specific transmit power level at which the terminal was instructed to transmit by a base station, when the monitoring module finds, through monitoring, that the terminal is currently in a first working mode, and to transmit the signal according to a second transmit power when the monitoring module finds, through monitoring, that the terminal is currently in a second working mode, wherein the first transmit power is greater than the second transmit power.

9. The terminal according to claim 8, wherein

the first working mode is a working mode that a user is still capable of using the terminal to perform a service normally when a distance between the terminal and the body of the user is at least a first distance threshold.

10. The terminal according to claim 9, wherein

the first power control submodule comprises:

a power control subunit, configured to transmit the signal according to the enhanced transmit power that is found by the power search subunit and corresponds to the specific transmit power level at which the terminal was instructed to transmit by the base station.

11. The terminal according to claim 8, wherein

the monitoring module is specifically configured to, if it is detected that the terminal performing a call service is connected to a headset or uses a handsfree function, or it is detected that the terminal only performs a data service, determine that the terminal is in the first working mode;
