After detecting the GPIO2 port and being drawn high, then realize the radio-frequency emission power of second transmitter module 3040 in the CDMA module 304 is obtained.Particularly, in time, can carry out directly obtaining before the radio-frequency transmissions, also can after radio-frequency transmissions, obtain through the feedback circuit in the CDMA module 304 at second transmitter module 3040; On obtain manner; Can be through the connection line between connection line, LTE module 302 and the processor 306 between CDMA module 304 and the processor 306; After by CDMA module 304 radio-frequency emission power of second transmitter module 3040 being sent to processor 306; Be forwarded to LTE module 302 by processor 306; Also independent detection module 308 (like power detector) can be set in addition, directly second transmitter module 3040 be detected, and the radio-frequency emission power that detection obtains is forwarded to LTE module 302.
LTE module 302 itself is preset with the complete machine radio-frequency power with CDMA module 304 residing terminals; The then radio-frequency emission power and preset complete machine radio-frequency power of second transmitter module 3040 that will combine to receive of the control module 3022 in the LTE module 302; Thereby calculate the desirable radio-frequency emission power of first transmitter module 3024 in the LTE module 302, control first transmitter module 3024 then and carry out the emission of radiofrequency signal according to this ideal radio-frequency emission power.
Fig. 4 shows the particular flow sheet of the method for adjustment of terminal radio frequency transmitting power according to an embodiment of the invention.
As shown in Figure 4, the idiographic flow of the method for adjustment of terminal radio frequency transmitting power comprises according to an embodiment of the invention:
Step 402 supposes that the terminal comprises CDMA module and LTE module, and wherein, the CDMA module is used for voice communication service, and the LTE module is used for data service.On CDMA module and LTE module, there is the GPIO port respectively, between two GPIO ports, sets up data transmission link.When the CDMA module begins voice call, the GPIO port on the CDMA module is drawn high, and when the CDMA module finishes voice call, then this port is dragged down.
Step 406 is closed the CDMA power detection.
Step 408 judges whether the LTE module is carrying out data communication service, if then get into step 412, otherwise return step 404.
Step 412 is opened the CDMA power detection.Particularly, promptly the radio-frequency emission power to the CDMA module detects, and this testing process can directly be obtained before the CDMA module is carried out radio-frequency transmissions in time, also can after radio-frequency transmissions, obtain through the feedback circuit in the CDMA module; On obtain manner; Can be through the connection line between connection line, LTE module and the processor between the processor at CDMA module and terminal; After by the CDMA module self radio-frequency emission power being sent to processor, be forwarded to the LTE module, also independent detection module (like power detector) can be set in addition by processor; Directly the CDMA module is detected, and the radio-frequency emission power that detection obtains is forwarded to the LTE module.
Step 414 through the CDMA power detection, is obtained the radio-frequency emission power P of CDMA
CDMA
There are preset complete machine radio-frequency emission power in step 416, terminal itself, with this complete machine radio-frequency emission power and P
CDMAAfter analyzing jointly, obtain the desirable radio-frequency emission power P of LTE module
LTE1
Step 418 is to the original radio frequency transmitting power P of LTE module
LTE0Adjust, make it with P
LTE1Launch, in the hope of the complete machine radio-frequency emission power at terminal is realized reducing.
More than be described with reference to the accompanying drawings technical scheme of the present invention, considered in the correlation technique, under the situation for the voice-and-data service concurrence; Can't realize adjusting for the radio-frequency emission power of a plurality of modules; Therefore, the invention provides the method for adjustment of a kind of terminal and a kind of terminal radio frequency transmitting power, can be when the voice-and-data service concurrence; Through the professional radio-frequency emission power of restricting data; With the complete machine transmitting power of control terminal, thereby when guaranteeing voice call quality, satisfy the SAR test request.
The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
