First embodiment
It is improved often by hardware to solve solution TDD noises at present, debugging difficulty is big, and circuit is very multiple
Miscellaneous, the problem of hardware cost increases, present embodiments provides a kind of multi-antenna terminal that is applied to (i.e. at least two antennas
Terminal, such as dual-antenna terminal, triantennary terminal etc.) on reduction TDD influence of noises method.It is this reality referring to Fig. 2, Fig. 2
The method basic flow chart of the reduction TDD influence of noises of example offer is provided, including：
S201：When terminal is in GSM mode, current work audio parts group is determined；
It should be understood that for terminal, TDD noises are the working methods due to the time division multiple acess under GSM standards
And generate.And existing multi-standard terminal currently on the market, therefore, for multi-standard terminal, terminal needs first to determine
Whether itself is under GSM mode.But for being only capable of in the terminal that GSM standards work, then can directly it carry out current
The determination step for the audio parts group that works.
In practical applications, there are two kinds of specific patterns under GSM standards, are GSM speech patterns and GSM online moulds respectively
Formula.Therefore in the present embodiment, GSM mode can be only GSM speech patterns (i.e. at this time only when terminal is in GSM speech patterns
When just execute the present embodiment provided reduction TDD influence of noises method each step), may also be only GSM online mould
Formula (the method for only just executing the reduction TDD influence of noises that the present embodiment is provided when terminal is in GSM online patterns at this time
Each step), can also simultaneously include GSM speech patterns and GSM online pattern (i.e. terminal is in equal when any GSM mode
Execute each step of the method for the reduction TDD influence of noises that the present embodiment is provided).Typically, TDD noises mainly exist
It is generated under GSM speech patterns, therefore considering for saving terminal resource, in a kind of specific implementation mode of the present embodiment,
It is GSM speech patterns that GSM mode, which can be arranged,.
In the present embodiment, work audio parts group includes at least one audio parts, and in the audio parts group that works
Included audio parts should be at working condition.
In the present embodiment, audio parts refer to the electronics device that can be received or be played to voice signal in terminal
Part, such as receiver, microphone, loud speaker, earphone, sound equipment etc..
In the present embodiment, the audio parts included in audio parts group that work can be the arbitrary audio device in terminal
Part, such as can be the arbitrary audio parts of terminal built-in, such as receiver, microphone, boombox, can also be that terminal is external
Arbitrary audio parts, such as external loudspeaker (loudspeaker, sound equipment), earphone etc..
But it should be noted that the spy that audio parts included in work audio parts group can also be pre-set
The audio parts that fixed audio parts are concentrated.It is audio parts that certain some audio parts can be preassigned in the present embodiment
The audio parts of concentration determine hereafter when determining work audio parts group according only to the audio parts of audio parts concentration
Work audio parts group.For example, setting the audio parts of preset audio parts concentration as earphone, loudspeaker.Then work as in terminal determination
When preceding work audio parts group, it is only necessary to determine whether that earphone and/or loudspeaker are in running order.Typically, eventually
The built-in audio parts in end can all be protected so that produced by the audio parts of terminal built-in on hardware or circuit structure
TDD noises reduce, but the protecting effect that the external audio parts of terminal then can not be protected or be generated is weaker.Cause
In a kind of specific implementation mode of the present embodiment, it includes earphone that the audio parts that preset audio parts are concentrated, which can be arranged, for this
At least one of with external loudspeaker.
It should be understood that since the audio parts that preset audio parts are concentrated may not include to own in terminal
Audio parts, therefore there may be the current work that can not determined current work audio parts group or determine at this time
Audio parts group is the situation of sky.The i.e. controllable default antenna of terminal continues to work as work antenna at this time.Here it needs
It will be clear that for terminal, default antenna is often set to realize the reception of initial signal.In addition, terminal is also
Other patterns other than GSM mode are there may be, while there is also do not need audio parts but antenna is needed to work
The case where, therefore for terminal, setting default antenna is will also tend to realize that the signal of these situations receives.
It is worth noting that, in the method for the reduction TDD influence of noises that the present embodiment is provided, signified terminal is more days
Line terminal.In fact, current multi-antenna terminal is and stale, (exist for example, see as a kind of dual-antenna terminal shown in Fig. 3
32 two antennas of antenna 31 and antenna), it is shown in Figure 4 be that (there are antenna 41, antenna 42 and antennas for a kind of triantennary terminal
43 3 antennas), in addition there are four antenna terminals, five antenna terminals etc., structure and dual-antenna terminal and triantennary terminal class
Seemingly, it will not enumerate herein.
S202：Preferred day corresponding with the work audio parts group is determined according to the work audio parts group determined
Line；
It should be noted that preferred antenna corresponding with work audio parts group refers in the present embodiment so that this is really
The most weak antenna of TDD noises in the work audio parts group made.It should be understood that the TDD described in the present embodiment makes an uproar
It refers to that generated entirety TDD noises are most in each in running order audio parts in the audio parts group that works that sound is most weak
It is weak.Meanwhile the power of TDD noises refers to each in running order audio parts in the audio parts group that works in the present embodiment
In noise sound caused by generated TDD noises whole size.
In the present embodiment, it is determined according to the work audio parts group determined corresponding with the work audio parts group
The concrete mode of preferred antenna includes at least following three kinds, any one mode may be used in the present embodiment to determine to work as
Preferred antenna corresponding to preceding work audio parts group.
Mode one：Can according to pre-save work audio parts group and antenna correspondence, by with current work
Make the corresponding antenna of audio parts group and is determined as preferred antenna.
In mode one, the correspondence of the audio parts group that works and antenna can obtain in laboratory environments.
Specifically, can be in laboratory environments, first so that terminal is under GSM mode, then under different audio scenes one by one
TDD noise testings are carried out as work antenna using different antennas, it is most weak to finally obtain TDD noises under each audio scene
That antenna.What needs to be explained here is that audio parts in running order in terminal under different audio scenes
Combination (work audio parts group) is often different, such as terminal in running order audio device when plain old telephone is answered
Part is receiver and microphone, when headset phone is answered (setting earphone has microphone) then in running order audio parts are ears
Machine.Special, if the combination of in running order audio parts is identical in terminal under certain several audio scene, engineer exists
An audio scene can be only chosen when detection to be detected.It should also be noted that, having obtained difference in laboratory environments
Audio scene under after most weak that antenna of TDD noises, need the work audio device that will be corresponded under each audio scene
That most weak antenna of the TDD noises that are corresponded under part group and the audio scene, which generates correspondence and recorded in terminal, to be protected
It leaves and.In the present embodiment, the correspondence of the audio parts group that works and antenna can be stored in end by forms such as charts
In end, such as preserved by form shown in following table one.
Table one
| Work audio parts group | Respective antenna |
| Receiver+microphone | Antenna 2 |
| Microphone+loud speaker | Antenna 1 |
| … | … |
| Earphone | Antenna 2 |
In fact, due to the generated TDD noises in an audio parts power often and the audio parts with
The distance between antenna work in inverse ratio, i.e., the remoter TDD noises that it is generated are often with a distance from work antenna for audio parts
It is weaker.Therefore for the work audio parts group under an audio scene only include an audio parts or comprising multiple sounds
When frequency device is respectively positioned on the same side of terminal, can also directly determine apart from an audio parts or it is multiple be located at terminal it is same
The antenna that the audio parts of side are farthest is antenna corresponding with the work audio parts group under the audio scene.For example, see Fig. 5
Shown in terminal, microphone 51 and loud speaker 52 be set to terminal bottom side, and terminal upper and lower ends are respectively equipped with antenna 53 and antenna 54,
If the work audio parts group under present video scene is microphone and loud speaker, then can directly determine and work at present audio device
The corresponding antenna of part group is antenna 53.Antenna corresponding with audio parts group is determined using audio miracle and the distance of antenna
When, above-mentioned repeated detection need not be carried out, terminal resource and time are saved.
It should be understood that scheme one has universality.Because for a terminal, all structures are consistent
, therefore only need to obtain pair of work the audio parts group and antenna of a terminal with a terminal in laboratory environments
After should being related to, when producing or sell thereafter this terminal, directly the correspondence obtained under laboratory environment can be protected
It is stored in each terminal, terminal no longer needs self to carry out looking for for correspondence in use.In addition, scheme one for
(mainly the position of aerial position structure and audio parts is tied with for the other-end of the terminal close structural of test in laboratory
Structure is close with the terminal of test in laboratory), the work audio parts group of the terminal of test in laboratory and the correspondence of antenna can
To be grafted directly on this Terminal Type, it is no longer necessary to detect again.

S601：Whether the correspondence of current work audio parts group and a certain antenna has been preserved in detection terminal；
If so, going to step S602；Otherwise, step S603 is gone to.
In scheme two, the correspondence of the audio parts group that works and antenna is gradually added simultaneously during the use of user
It preserves.Therefore, if when user's using terminal, the work audio parts group under present video scene has been saved before
It (has been had confirmed during use before with the correspondence of a certain antenna and has used current work audio parts group
When, the most weak antenna of TDD noises in the audio parts group that works), then it can directly invoke correspondence and directly determine preferably
Antenna executes step S602.If do not preserved when user's using terminal, in terminal current work audio parts group with it is a certain
The correspondence of antenna, then terminal needs be detected, to find out antenna corresponding with current work audio parts group.
S602：Determine that antenna corresponding with current work audio parts group is preferred antenna.
It should be understood that for terminal, the position relationship of each antenna and each audio parts is fixed.Therefore i.e.
Make under different signal environments, each antenna is also constant to the strong or weak relation of the TDD influence of noises caused by each audio parts
's.Therefore the preferred antenna of the current work audio parts group of record is also still current work under the present circumstances before
The preferred antenna of audio parts group.It is antenna A that the corresponding preferred antenna of earphone is had recorded before such as, then under the present circumstances
The corresponding preferred antenna of earphone is still necessarily antenna A.Therefore by searching for the current work audio preserved in scheme two
The correspondence of device group and a certain antenna, you can directly confirm the preferred antenna of current work audio parts group.
S603：The work audio current as work antenna and when recording each Antenna Operation successively by each antenna of terminal
The TDD noise figures generated in device group；
In the present embodiment, it is m seconds (m is more than 0) that each antenna, which can be arranged, as the working time of work antenna, in turn
It is recorded in each antenna in this m seconds and makes the TDD noise figures generated in current work audio parts group.In the present embodiment,
The TDD noise figures of record can be the TDD noise figures that each antenna to generate in current work audio parts group in m seconds
Peak value or average value etc..
It should be understood that for terminal, in baseband chip can grab frequency from audio parts and be
The TDD noise signals of 217Hz, and then TDD noise figures can be obtained according to the TDD noise signals grabbed.
S604：The antenna that corresponding TDD noises are most weak in each antenna is determined according to each TDD noise figures of record；
S605：Determine that the most weak antenna of TDD noises is preferred antenna corresponding with current work audio parts group；
Only include a sound for work audio parts group it should be understood that in addition to aforesaid way obtains preferred antenna

Each audio parts distance directly is determined that apart from farthest antenna be preferred antenna in device group.
S606：Record and preserve the correspondence of the most weak antenna of the TDD noises and current work audio parts group.
Particularly, for directly to determine by the way of preferred antenna using distance, it should be record at this time and protects
Deposit the correspondence of the preferred antenna and current work audio parts group.
It should be noted that stringent sequential relationship is not present in above-mentioned steps S605 and step S606.That is step S605 can
It to be carried out before step S606, can also carry out, can also be carried out at the same time with step S606 after step S606.
Scheme three：Flow diagram shown in Figure 7 is determined corresponding with current work audio parts group preferred

Audio parts group can only carry out one-time detection, follow-up only to carry out corresponding pass to obtain corresponding correspondence and preserve
The calling of system.And it is then required to detect again and look for when carrying out the audio work under GSM mode each time in mode three
Go out corresponding preferred antenna.

Work antenna is then switched to preferred antenna by antenna；If preferred antenna is exactly default antenna, cutting for work antenna is no longer executed
Change operation.
It should be understood that for terminal, under different communication environments, communicated sometimes using default antenna
Audio parts may also can't be made to generate TDD noises, or the TDD noises very little generated can be ignored.Therefore at this time into
The switching of row antenna may then cause the unnecessary wasting of resources, while the antenna after switching can be not so good as to write from memory for the transmitting-receiving of signal
It is good to recognize antenna.Therefore, in the present embodiment when terminal is in GSM mode, current work audio device can also be being determined
The TDD noise parameter current to terminal is detected before part group, and then when the value of TDD noise parameters is more than predetermined threshold value,
It determines current work audio parts group again and finds corresponding preferred antenna to switch over.For the value of TDD noise parameters
The case where less than or equal to predetermined threshold value, then can no longer execute above-mentioned flow as shown in Figure 2, and directly use default antenna for
Work antenna works.
It needs to know, when terminal works are in GSM standards, the bigger generated TDD noises of signal transmission power
Will be bigger, therefore can determine the need for executing by detecting current signal transmission power above-mentioned as shown in Figure 2
Flow.In addition, the baseband chip in terminal can also directly grab TDD noise signals, therefore can also be made an uproar by detecting TDD
Sound value determines the need for executing above-mentioned flow as shown in Figure 2.Therefore, the TDD noise parameters in the present embodiment can wrap
Include at least one of TDD noise figures and signal transmission power.
It should be understood that when terminal 100 as shown in Figure 1 is multi-antenna terminal, reduction TDD provided in this embodiment
Each step in the method for influence of noise can independently be realized by terminal 100 as shown in Figure 1.Specifically, can pass through
