In having technology to describe, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only
Some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, also
Other accompanying drawing can be obtained according to these accompanying drawings.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
As it is shown in figure 1, the embodiment of the present invention provides a kind of optimization method launching power switching point, specifically include following step
Rapid:
Step 1, presets with reference to mobile terminal emitting power switching point.
In this step, prepare a Radix codonopsis pilosulae in advance and examine mobile terminal.Specifically, it is possible to use the JINJI of product line
(standard mobile terminal of calibration production line radio frequency design) is as with reference to mobile terminal.In product line JINJI spot check process
In, and according to mobile terminal launch in centre under power balance in signal nonlinear indicator and radio-frequency current select one moderate
Value, is set as launching power switching point.
Step 2, detects mobile terminal to be measured and with reference to mobile terminal under the same PA gain-state, a certain gain level
Launch power difference.
In this step, the tranmitting frequency of mobile terminal can be tested by comprehensive test instrument.Wherein, comprehensive test instrument is this area
Measurement mobile phone radio frequency index instrument known to technical staff, does not repeats for concrete test process here.For reference
The detection of mobile terminal, can record a certain gain under a certain gain-state during product line JINJI spot check
The actual power of grade.For mobile terminal to be measured, then according to comprehensive test instrument under the same gain level of same gain-state, inspection
Rope RF transceiver transmits signals to reach the transmitting power of radio frequency point test bench.
Wherein, under different communication modes, in mobile terminal, the gain-state of PA is also different.Generally GSM has 3～4
PA gain-state, and TD-SCDMA, WCDMA, LTE or CDMA generally have 2～3 PA gain-state.Each PA gain-state
Comprise multiple gain level.In high-pass platform, the gain level of GSM refers to that (RF gain index, rf gain refers to RGI
Number) grade；For CDMA, WCMDA, TD-SCDMA, LTE, gain level then refer to AGC (automatic gain control,
Automatic growth control) grade.
Illustrating, the PA gain-state of CDMA BC0 frequency range includes: PA state 1 and PA state 0.Wherein, PA
The gain level of state 1 is from 40 to 73, and the gain level of PA state 0 is from 0 to 60.Power between each gain level
Difference 1dBm.PA gain-state is different, and the output of same gain level is also different.Generally, under same gain level
(such as gain level is 50), the PA state 0 power than PA state 1 is low.Owing to PA state 1 uses in high-gain
Under state, PA state 0 uses under low gain state.In order to take into account electric current optimization, preferably under low gain state, detection is same
Transmitting power during one gain level.
Step 3, optimizes mobile terminal to be measured according to reference to mobile terminal emitting power switching point and transmitting power difference
Launch power switching point.
Wherein, there are two between each two PA gain-state and launch power switching point: be respectively high-gain to low gain
Downward switching point and low gain switching up a little to high-gain.The transmitting power switching point optimized in the present invention is downward
Switching point.A little it is usually definite value, for 3dbm with downward switching point difference owing to switching up.As long as therefore adjusting and switching downwards merit
Rate switching point, the power switching point switched up adjusts according to " definite value ".Such as, downwardly and upwardly power switching point is distinguished
For 0dBm, 3dBm.If the switching point of switching optimizes 1dBm downwards, then the downwardly and upwardly power switching point after optimizing is respectively
1dBm, 4dBm.
Illustrating, the gain level of PA state 1 is 73～40, the power bracket under different gains grade is-
2.7dBm～29.9dBm；The gain level of PA state 0 is 60～0, and the power bracket under different gains grade is 15.4dBm
～-49dBm.
At PA state 1, power is that 5dBm drops to-0.5dBm, owing to downward switching point is 0dBm, then drops to
During 0dBm, then switched to PA state 0 by PA state 1.If instead PA is increased beyond 3dBm by-0.5dBm, and upwards
Switching point is 3dBm, then when rising to 3dBm, then switched to PA state 1 by PA state 0.
Specifically, when being optimized, when mobile terminal emitting power to be measured is more than reference mobile terminal emitting power,
Then with reference on the basis of mobile terminal emitting power switching point plus launching power difference accordingly, be after optimization is to be measured
Mobile terminal emitting power switching point；When mobile terminal emitting power to be measured is less than during with reference to mobile terminal emitting power, then exist
Launch power difference accordingly with reference to deducting on the basis of mobile terminal emitting power switching point, be the movement to be measured after optimization
Terminal transmission power switching point；When mobile terminal emitting power to be measured is equal to reference to mobile terminal emitting power, then terminate optimizing.
Further, movement to be measured is being optimized according to transmitting power switching point and the transmitting power difference with reference to mobile terminal
Before the transmitting power switching point of terminal, needs judgement transmitting power difference and the size of predetermined threshold value:
If launching power difference to be less than or equal to predetermined threshold value, then terminate optimizing；
If launching power difference to be more than predetermined threshold value, then according to reference to mobile terminal emitting power switching point and transmitting power
Difference optimizes the transmitting power switching point of mobile terminal to be measured.
Further, movement to be measured is being optimized according to transmitting power switching point and the transmitting power difference with reference to mobile terminal
After the transmitting power switching point of terminal, the method also includes:
Under non-signaling pattern, the transmitting signal nonlinear indicator measuring mobile terminal to be measured is the most up to standard.
Wherein, when detecting radio frequency amplifier nonlinear indicator and being the most up to standard, using of different communication networks is different
Parameter detects.Such as in LTE, WCDMA ACLR (Adjacent Channel Leakage Ratio, adjacent channel leakage
Than) and spectral emission template, GSM are modulation spectrum and switch frequency spectrum, TD-SCDMA be ACLR (adjacent channel is revealed and compared) and
CDMA is TX conducted Spurious emisions.For how to carry out nonlinear indicator detection according to above-mentioned parameter,
Being already belonging to the technology known to skilled person, it will not be described here.
When transmitting information carries out nonlinear indicator detection, need to test near transmitting power switching point.Example
If PA State 0 is low gain mode, then need to carry out under PA State 1 state slightly below launching power switching point non-
Linear index is tested；If nonlinear indicator is the most up to standard, then by reducing power switching point raising nonlinear indicator.Specifically, root
Mobile terminal emitting power switching point to be measured is gradually reduced, till nonlinear indicator is up to standard according to default stepping power.Example
As, pre-set with 0.5dBm for stepping power, the transmitting power switching point after optimization is 13dBm, then survey after reducing 0.5dBm
Whether nonlinear indicator is up to standard for amount (i.e. 12.5dBm): if the most up to standard, then continue to measure nonlinear indicator at 12dBm up to standard, until
Till up to standard.
When under non-signaling pattern, measure the transmitting signal nonlinear indicator of mobile terminal to be measured up to standard time, then will adjust
After transmitting power switching point store.Such as, for high-pass platform, by static for the write of this transmitting power switching point NV
?.Wherein, saving, in static NV, some parameter values that modules in system operation may be used, user is can not
Arbitrarily access, can only be written and read by testing tool QXDM.

When state comprises a certain gain level, then under low gain state, power difference is launched in detection.
Further, the power switching point of launching optimizing that unit 23 optimizes is high gain state to the power of low gain state
Switching point.
Further, this device includes judging unit 24, for according to reference to mobile terminal transmitting power switching point and
Before launching the transmitting power switching point that power difference optimizes mobile terminal to be measured, it is judged that transmitting power difference is big with predetermined threshold value
