And it can be implemented in accordance with the contents of the specification, and in order to allow above and other objects of the present invention, feature and advantage can
It is clearer and more comprehensible, the followings are specific embodiments of the present invention.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only
Some embodiments of the present invention, for those of ordinary skill in the art, without any creative labor, also
Other drawings may be obtained according to these drawings without any creative labor.
Fig. 1 is the flow chart of transmission power switching point optimization method in the embodiment of the present invention；
Fig. 2 is the structural block diagram that transmission power switching point optimizes device in the embodiment of the present invention.
Specific embodiment
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.
As shown in Figure 1, the embodiment of the present invention provides a kind of optimization method of transmission power switching point, following step is specifically included
It is rapid:
Step 1, it presets with reference to mobile terminal emitting power switching point.
In this step, one is prepared in advance with reference to mobile terminal.Specifically, the golden machine of product line can be used
(standard mobile terminal of calibration production line radio frequency design) is as with reference to mobile terminal.Process is examined in product line gold machine point
In, and according to mobile terminal under intermediate transmission power in signal nonlinear indicator and radio-frequency current tradeoff select one it is moderate
Value, is set as transmission power switching point.
Step 2, mobile terminal to be measured is detected and with reference to mobile terminal under the same PA gain-state, a certain gain level
Transmission power difference.
In this step, the tranmitting frequency of mobile terminal can be tested by comprehensive test instrument.Wherein, comprehensive test instrument is this field
Measurement mobile phone radio frequency index instrument known to technical staff, does not here repeat them here specific test process.For reference
The detection of mobile terminal, can be during product line gold machine point be examined, a certain gain that is recorded under a certain gain-state
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 the transmission power up to radio frequency point test bench.
Wherein, under different communication modes, the gain-state of PA is also different in mobile terminal.Usual GSM has 3~4
PA gain-state, and TD-SCDMA, WCDMA, LTE or CDMA usually have 2~3 PA gain-states.Each PA gain-state
Include multiple gain levels.In high-pass platform, the gain level of GSM refers to that (RF gain index, rf gain refer to RGI
Number) grade；For CDMA, WCMDA, TD-SCDMA, LTE, gain level then refer to AGC (automatic gain control,
Automatic growth control) grade.
For example, 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
Differ 1dBm.PA gain-state is different, and the output power of same gain level is also different.In general, under same gain level
(such as gain level is 50), PA state 0 is lower than the power of PA state 1.Since 1 use of PA state is in high-gain
Under state, 0 use of PA state is under low gain state.Electric current optimizes in order to balance, detects preferably under low gain state same
Transmission power when one gain level.
Step 3, mobile terminal to be measured is optimized according to reference mobile terminal emitting power switching point and transmission power difference
Transmission power switching point.
Wherein, there are two transmission power switching points between every two PA gain-state: respectively high-gain to low gain
Downward switching point and low gain switching up a little to high-gain.The transmission power switching point optimized in the present invention is downward
Switching point.It is usually a little definite value with downward switching point difference due to switching up, is 3dbm.As long as therefore adjusting switching function downwards
Rate switching point, the power switching point switched up are adjusted according to " definite value ".For example, downwardly and upwardly power switching point is distinguished
For 0dBm, 3dBm.If the switching point optimization 1dBm switched downwards, the downwardly and upwardly power switching point after optimization are respectively
1dBm, 4dBm.
For example, 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.
In PA state 1, power is that 5dBm drops to -0.5dBm, since downward switching point is 0dBm, is then dropped to
When 0dBm, then PA state 0 is switched to by PA state 1.If instead PA is increased beyond 3dBm by -0.5dBm, and upward
Switching point is 3dBm, then when rising to 3dBm, is then switched to PA state 1 by PA state 0.
Specifically, when optimizing, when mobile terminal emitting power to be measured is greater than with reference to mobile terminal emitting power,
Corresponding transmission power difference is then added on the basis of reference mobile terminal emitting power switching point, it is to be measured after as optimizing
Mobile terminal emitting power switching point；When mobile terminal emitting power to be measured is less than with reference to mobile terminal emitting power, then exist
Movement to be measured with reference to corresponding transmission power difference is subtracted on the basis of mobile terminal emitting power switching point, after as optimizing
Terminal transmission power switching point；Mobile terminal emitting power is referred to when mobile terminal emitting power to be measured is equal to, then terminates optimization.
Further, movement to be measured is being optimized according to the transmission power switching point and transmission power difference of reference mobile terminal
Before the transmission power switching point of terminal, need to judge the size of transmission power difference and preset threshold:
If transmission power difference is less than or equal to preset threshold, optimization is terminated；
If transmission power difference is greater than preset threshold, according to reference mobile terminal emitting power switching point and transmission power
Difference optimizes the transmission power switching point of mobile terminal to be measured.
Further, movement to be measured is being optimized according to the transmission power switching point and transmission power difference of reference mobile terminal
After the transmission power switching point of terminal, this method further include:
Under non-signaling mode, whether the transmitting signal nonlinear indicator for measuring mobile terminal to be measured is up to standard.
Wherein, detect radio frequency amplifier nonlinear indicator it is whether up to standard when, different communication networks using different
Parameter is detected.Such as ACLR (Adjacent Channel Leakage Ratio, adjacent channel leakage in LTE, WCDMA
Than) and spectral emission template, GSM be modulation spectrum and switch frequency spectrum, TD-SCDMA be ACLR (adjacent channel leakage ratio) and
CDMA is TX conducted Spurious emisions.For how according to above-mentioned parameter carry out nonlinear indicator detection,
Technology known to skilled person is already belonged to, it will not be described here.
When carrying out nonlinear indicator detection to transmitting information, need to be tested near transmission power switching point.Example
If PA State 0 is low gain mode, then need to carry out under 1 state of PA State of slightly below transmission power switching point non-
Linear index test；If nonlinear indicator is not up to standard, nonlinear indicator is improved by reducing power switching point.Specifically, root
Mobile terminal emitting power switching point to be measured is gradually reduced according to preset stepping power, until nonlinear indicator is up to standard.Example
Such as, the transmission power switching point preset using 0.5dBm as stepping power, after optimization is 13dBm, then surveys after reducing 0.5dBm
Measuring (i.e. 12.5dBm), whether nonlinear indicator is up to standard: if it does not meet the standards, then continuation is up to standard in 12dBm measurement nonlinear indicator, until
Until up to standard.
Under non-signaling mode, measure mobile terminal to be measured transmitting signal nonlinear indicator it is up to standard when, then will adjustment
Transmission power switching point afterwards is stored.For example, static state NV is written in the transmission power switching point for high-pass platform
?.Wherein, some parameter values that modules may be used in system operation are saved in static NV, user is cannot
It arbitrarily accesses, can only be written and read by testing tool QXDM.
