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 some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
Fig. 1 shows the flow chart of the multiple antennas optimization method of one embodiment of the invention, is applied to mobile terminal, mobile
Terminal includes more antennas, and multiple antennas optimization method includes:
Step S1: target scene locating for identification mobile terminal.
In the present embodiment, for the difference of scene locating for mobile terminal, different antenna prioritization schemes is taken.Thus
In the step, the target scene that mobile terminal is presently in is identified first.
Target scene transverse screen scene, vertical screen scene, call scene, scene of game etc..
For example, mobile terminal includes upper and lower two antennas, in the case where mobile terminal is in transverse screen scene, based on use
The posture of mobile terminal is held at family, and two hands are just held on antenna, therefore the interference caused by aerial signal is larger；Mobile whole
In the case that end is in vertical screen scene, the posture of mobile terminal is held based on user, two hands are not held on antenna, therefore to day
It is interfered caused by line signal smaller.
For another example, different based on the currently running interface of mobile terminal, such as interface, call interface, therefore it is locating
Scene is also different, and under different scenes, disturbing factor is different, and the annoyance level caused by aerial signal is also different, therefore antenna
Performance parameter it is also different.
Step S2: first performance parameter of the more antennas under target scene is obtained respectively.
In this step, two kinds of implementations are included at least.
In one implementation, after identifying target scene locating for mobile terminal, according to the feature of target scene, to more
The performance of root antenna carries out analysis assessment, to obtain first performance parameter of the more antennas under target scene.
In another implementation, after identifying target scene locating for mobile terminal, it can obtain in mobile terminal and store
History first performance parameter of the more antennas under target scene.
Step S3: determine that first performance parameter in more antennas meets at least one target antenna of default capabilities parameter.
Standard according to assessment performance is different, and the established standards of default capabilities parameter are also different.For example, the mark of assessment performance
Standard includes performance is poor, better performances, performance are good etc., and accordingly, it is good that the setting of default capabilities parameter can be performance.
In this step, if the first performance parameter of at least one antenna obtained is that performance is good, at least one antenna
First performance parameter meet default capabilities parameter.
Therefore, in this step, the quantity of determining target antenna can be one, be also possible to more.
Preferably, the target antenna that first performance parameter meets default capabilities parameter in more antennas is also possible to: more
A best antenna of first performance performance parameters in antenna.Therefore, default capabilities parameter here in the form of comparative degree into

Can be ideal, for receiving and transmitting signal not by any interference, the performance parameter of each antenna can satisfy default capabilities parameter.
Illustratively, 5G mobile terminal is in the case where locating any scene other than free state, such as scene of game, due to holding for hand
It the objective factors such as holds, the characteristic parameter of each antenna is caused to be more big changes.Accordingly, the fisrt feature parameter of antenna A be A1,
The fisrt feature parameter of antenna B is B1, the fisrt feature parameter of antenna C is C1, the fisrt feature parameter of antenna D is D1, this
The set of characteristic parameters of each antenna is { A1, B1, C1, D1 } under scape.
Illustratively, for the ease of difference, mobile terminal under more scenes, the n-th characteristic parameter of antenna A be An,
The n-th characteristic parameter of antenna B is Bn, the n-th characteristic parameter of antenna C is Cn, the n-th characteristic parameter of antenna D is Dn, thus n-th
Set of characteristic parameters is { An, Bn, Cn, Dn }.
Preferably, the first scene is any scene in transverse screen scene, vertical screen scene, call scene, scene of game etc..Its
In, in the case that mobile terminal is in the first scene, the characteristic parameter of the antenna of acquisition is second feature parameter.
Therefore, in this step, set of characteristic parameters of each antenna under different scenes is obtained, is carried out as historical data
Storage.
Preferably, the characteristic parameter of each antenna can be acquired by the related sensor in mobile terminal.
Accordingly, step S1 includes:
Step S11: in the case where mobile terminal is in the first scene, the target signature ginseng of more antennas is obtained respectively
Number.
In this step, the case where whether the first scene that mobile terminal is presently in unidentified out is target scene
Under, obtain the target signature parameter of more antennas, and composite object characteristic parameter respectively first.
Step S12: it is all larger than in the target signature parameter of every antenna with the similarity of corresponding second feature parameter pre-
If in the case where value, determining that the first scene is target scene.
If in target signature parameter sets, the second of the respective antenna of the target signature parameter and aforementioned storage of every antenna
The similarity of characteristic parameter is greater than preset value, then illustrates the corresponding scene of target signature parameter field corresponding with second feature parameter
Disturbing factor present in scape is identical, then identifies that the first scene is target scene.
In the present embodiment, a kind of method that identification mobile terminal is presently in scene is provided.Because mobile terminal is in spy
There is general character, for example, mobile terminal is under transverse screen scene, user's hand griping position is fixed, therefore same position under fixed scene
The characteristic parameter for the antenna set must be changed within the scope of one.To which different scenes can be stored in advance in mobile terminal
Under each antenna features parameter sets, and then be used for subsequent identification.As it can be seen that recognition methods provided in this embodiment is from objective spy
Sign is set out, and the accuracy rate of identification is higher.
On the basis of embodiment shown in Fig. 2, Fig. 4 shows the flow chart of another embodiment of the present invention, step S5 it
Afterwards, further includes:
Step S6: according to the second feature parameter of more antennas, the first performance parameter of more antennas is obtained respectively.
Preferably, the performance parameter of each antenna is detected using the transmitting-receiving access inside mobile terminal.
For example, mobile terminal is under free state, the performance parameter of antenna A is a0, the performance parameter of antenna B be b0,
The performance parameter of antenna C is c0, the performance parameter of antenna D is d0, further component property parameter sets be a0, b0, c0,
d0}。
For another example, mobile terminal is under scene of game, the performance parameter of antenna A is a1, the performance parameter of antenna B be b1,
The performance parameter of antenna C is c1, the performance parameter of antenna D is d1, further component property parameter sets be a1, b1, c1,
d1}。
For another example, mobile terminal is under any scene, the performance parameter of antenna A is an, the performance parameter of antenna B be bn,
The performance parameter of antenna C is cn, the performance parameter of antenna D is dn, further component property parameter sets be an, bn, cn,
dn}。
Wherein, in the case that mobile terminal is in the first scene, the characteristic parameter of the antenna of acquisition is second feature parameter,
The corresponding performance parameter obtained is first performance parameter.
Step S7: the mapping relations of the second feature parameter Yu first performance parameter of every antenna under the first scene are established.
The attainable performance parameter of the characteristic parameter of each antenna under first scene and institute is stored, and establishes and reflects one by one
Penetrate relationship.
Accordingly, step S3 includes:
Step S31: according to the mapping relations of the second feature parameter Yu first performance parameter of every antenna under the first scene,
Obtain the first performance parameter for meeting default capabilities parameter.
Step S32: the corresponding antenna of first performance parameter for meeting default capabilities parameter is determined as target antenna.
In step S31 and step S32, after identifying that the first scene is target scene, reflected according to the first scene is corresponding
Relationship is penetrated, available into first performance parameter sets, first performance parameter can satisfy the antenna of default capabilities parameter, from
And target antenna can be directly determined according to the corresponding mapping relations of the first scene, and work antenna is switched to target antenna.
In the present embodiment, the characteristic parameter of each antenna under any scene is stored in advance, and according to characteristic parameter to each
The performance parameter for each antenna that the detection of antenna performance obtains, and mapping relations are formed, thus after identifying target scene, it can be straight
It connects mapping relations according to the pre-stored data and determines target antenna.Therefore, user uses mobile terminal under any scene, can
Ensure that Antenna Operation is in optimum state, optimizes antenna performance under more scenes to realize, improve user experience.
On the basis of the embodiment shown in fig. 4, Fig. 5 shows the flow chart of another embodiment of the present invention, step S12 it
Afterwards, further includes:
Step S8: according to the target signature parameter of more antennas, the target capabilities parameter of more antennas is obtained respectively.
Step S9: the mapping relations of the second feature parameter and first performance parameter of every antenna under the first scene are updated.
In the case where determining the first scene is target scene, the target signature parameter of more antennas is obtained in step S11
Later, can based on the performance of each antenna of target signature parameter detecting of acquisition, to obtain the target capabilities parameter of each antenna, thus
Update the mapping relations of the second feature parameter Yu first performance parameter of every antenna under the first scene.
In the present embodiment, in user during continuing on, the characteristic parameter under Same Scene is constantly updated, and
Corresponding performance parameter, to be used for a long time based on user with specific customary way, progress real-time storage update, under each scene
The characteristic parameter of each antenna and corresponding performance parameter can settle out.To identify the target field that mobile terminal is presently in
Jing Hou, it will be able to which mapping relations according to the pre-stored data are rapidly switched to the antenna of optimum performance, and then more intelligent, rapid
Ground optimizes the real-time performance of mobile terminal antenna, promotes user experience.
For example, under transverse screen scene, according to the mapping relations of storage it is found that the performance of antenna C is best, to directly switch
For antenna C.At the same time, the collection apparatus and performance detection of each antenna are carried out, the performance for obtaining antenna D is best, to update
Mapping relations under transverse screen scene.It, can be according to updated mapping relations, directly when mobile terminal is again under transverse screen scene
It connects and is switched to antenna D.
Preferably, mobile terminal includes 4 antennas.
