Based on foregoing description, detect that secondary antenna switching is completed in acquisition when completing the switching of previous secondary antenna at the t2 moment
When switch over the antenna switching threshold 5dbm i.e. above-mentioned of judgement, and calculated by the value when carrying out antenna switching again
Antenna switching threshold.To which when carrying out antenna switching again, the RSSI of even each antenna meets antenna switching threshold i.e.
5dbm also switches without antenna, only just carries out antenna when the new antenna switching threshold that satisfaction is calculated based on 5dbm
Switching.And with the continuous progress of antenna handover process, antenna switching threshold also keeps dynamic change.In addition, according to preceding primary
Antenna switching threshold when antenna switching threshold when switching carries out antenna switching to calculate again can according to different application scene
Take different calculations.
Optionally, the antenna switching threshold switched according to i-th antenna calculates the antenna switching of i+1 secondary antenna switching
Threshold value, comprising:
A default adjusting parameter；
I+1 secondary antenna is calculated by preset algorithm according to the antenna switching threshold of i-th antenna switching and adjusting parameter
The antenna switching threshold of switching；The antenna that the antenna switching threshold of i+1 secondary antenna switching is greater than the switching of i-th antenna switches threshold
Value.
In the present embodiment, for prevent complete a secondary antenna switching when begin to be switched next time immediately.For example,
In a preceding handoff procedure, for antenna Ant0 as having switched primary antenna, antenna when set preceding primary switching switches threshold
Value is 5dbm, wherein the difference of the received signal strength of another antenna Ant1 and Ant0, which meets, is greater than 5dbm, therefore antenna occurs and cuts
It changes and chooses antenna Ant1 as primary antenna.When calculating antenna switching threshold when carrying out antenna switching again, can pass through
Preset algorithm such as addition algorithm, antenna switching threshold in preceding primary switching on the basis of, increase by an adjusting parameter value such as 2dbm
Come obtain carrying out next time switching when for determining the antenna switching threshold of the difference of destinations traffic parameter such as RSSI, i.e. 5dbm+
2dbm=7dbm, and so on, the subsequent relatively previous total phase of antenna switching threshold of antenna switching threshold when switching over again
To 2dbm is increased, that is, be followed successively by 7dbm, 9dbm, 11dbm ... therefore, with the lasting carry out antenna switching threshold of switching behavior
Also continue dynamic change.In addition, preset algorithm can also be multiplication algorithm, then a weighted factor is set by adjusting parameter,
Such as 1.2, it can be cut again according to the product of the weighted factor and antenna switching threshold when preceding primary switching to determine at this time
Antenna switching threshold when changing, i.e. 5dbm × 1.2=6dbm.
S303, the destinations traffic parameter for obtaining multi-antenna terminal, antenna when being switched according to i+1 secondary antenna switch threshold
It is worth, judges whether to need to carry out i+1 secondary antenna switching, destinations traffic parameter is used to characterize the performance of antenna.
Based on foregoing description, current primary antenna, that is, aforementioned Ant1 obtains the destinations traffic of each antenna of multi-antenna terminal at this time
Parameter simultaneously thereby determines that target primary antenna such as Ant0, according to aforementioned calculating process it is obtained again carry out antenna switching when needs
The antenna switching threshold of satisfaction is 7dbm, determines whether the difference of the received signal strength of Ant0 and Ant1 is greater than 7dbm, if
Meet and just determines the next secondary antenna switching of progress, even if when difference is 6dbm, although antenna when being greater than preceding primary switching is cut
Change threshold value 5dbm, but due to whether meeting the condition switched again and be not based on same antenna switching threshold and determined,
Because antenna switching threshold when switching over again is changed, and with the antenna switching threshold 7dbm phase currently calculated
It than being not out, therefore does not do and switches when difference is 6dbm, thus delayed the switching of antenna.
Optionally, i+1 is calculated by preset algorithm according to the antenna switching threshold of i-th antenna switching and adjusting parameter
After the antenna switching threshold of secondary antenna switching, further includes:
Whether the antenna switching threshold for judging the switching of i+1 secondary antenna is more than upper threshold；If it is not, be then calculated
The antenna switching threshold of i+1 secondary antenna switching is effective.
In the present embodiment, for prevent carry out antenna switching threshold adjustment when with antenna switching behavior continue into
Row and constantly become larger, it is contemplated that if more than when will antenna be switched when certain value to the target of multi-antenna terminal
Messaging parameter judgment criteria becomes excessively high, so that being difficult to reach antenna switching condition and influence the antenna of multi-antenna terminal just
Normal performance of handoffs.Day when therefore, it is necessary to based on a preset upper threshold such as 20dbm to the switching again being calculated
Line switching threshold is judged that the upper threshold is the threshold value for guaranteeing antenna switching and being normally carried out, as long as when switching again
Antenna switching threshold is no more than 20dbm, and then the calculated value is virtual value, can continue to carry out antenna switching according to preset rules
Determine and antenna switching threshold calculates.
Optionally, i+1 is calculated by preset algorithm according to the antenna switching threshold of i-th antenna switching and adjusting parameter
After the antenna switching threshold of secondary antenna switching, further includes:
Whether the antenna switching threshold for judging the switching of i+1 secondary antenna is more than upper threshold, if so, a selected correction value
As antenna switching threshold；Correction value include upper threshold value, the switching of i-th antenna antenna switching threshold, initial antenna cuts
Change threshold value.
Based on foregoing description, if from first secondary antenna switching persistently carry out antenna be switched to certain number when, when switching again
Antenna switching threshold to be difficult to the difference of destinations traffic parameter full
When the foot value, it is excessive that antenna switches difficulty, if or continuing to increase even if being currently able to satisfaction subsequent antenna switching threshold, meeting eventually
Cause antenna switching that can not continue, therefore, when antenna switching threshold is more than upper threshold when switching again, needs to meter
Obtained antenna switching threshold is modified and is returned to normal level, so as to maintain to carry out day according to preset rules
Line is switched and determined.In some embodiments, threshold can be switched using upper threshold 20dbm as antenna when switching over again
Value, then using 20dbm as the decision content of destinations traffic parameter when progress antenna switching again when carrying out antenna switching every time,
If subsequent carry out not continuing to carry out threshold calculations according to preset rules when antenna switching again.It, can be in other embodiments
The antenna switching threshold that the antenna switching threshold that this is calculated once switches over before being modified to, if then subsequent carry out again
It will also continue to determine with the revised threshold value when antenna switches, and antenna can not be carried out according still further to preset rules and switch threshold
Value calculates.It is, of course, also possible to which the antenna switching threshold that this is calculated is modified to day when initial time carries out antenna switching
Line switching threshold, i.e., initial value 5dbm as the aforementioned, in this case, if it is subsequent carry out can continuing when antenna switching again according to
Preset rules carry out antenna switching determination and antenna switching threshold calculates.
It should be noted that in some embodiments adjusting parameter can also be set to a variable value, thus in antenna
The dynamic corrections that antenna switching threshold can also be carried out while antenna switching threshold dynamic adjusts, example are realized during switching
Such as, the collection of antenna switching threshold once switched over before selecting is combined into such as { 6,9,12,15,18,21 ... ... } dbm, corresponding
The set of adjusting parameter may be configured as such as { 5,3,3,1,1, -3 ... } dbm, then according to it is corresponding it is preceding once switch over when
Antenna switching threshold when switching over again that antenna switching threshold and adjusting parameter are calculated be 11,12,15,16,
19,18 ... } dbm avoids the normal switching of antenna by shadow so that the flexibility of antenna switching threshold and validity are stronger
It rings.In the present embodiment, the configuration mode of antenna switching threshold and adjusting parameter mapping relations when previous secondary antenna switches can
To select system configuration or manual configuration, system configuration voluntarily to be configured by system as shown in figure 4, user can according to need,
Manual configuration can then require user's self-setting respectively adjusting parameter corresponding with antenna switching threshold when preceding primary switching.

Method includes:
S501, it detects whether to complete the switching of i-th antenna, antenna switching is for redefining at least three groups of antennas and main receipts
The connected relation between access, auxiliary receiving path is sent out, to select new primary antenna, auxiliary antenna and spare antenna.If so,
Step S502 is executed, continues to execute this step S501 if it is not, then returning.
The specific implementation process of the step can be with reference to the related narration in above-mentioned first embodiment, and details are not described herein.
S502, the target primary antenna when detecting that completing i-th antenna switches, after counting the switching of i-th antenna respectively
When total when being switched to the total degree of primary antenna in preset period of time with current primary antenna and/or being used as primary antenna
It is long, determine that the use of target primary antenna and current primary antenna after the switching of i-th antenna is preferential according to total degree and/or total duration
Grade.
It is switched to the higher frequency for illustrating whithin a period of time to use the antenna as primary antenna of total degree of primary antenna
Rate is higher, and the more long then explanation resident time on this antenna of total duration when being used whithin a period of time as primary antenna
It is longer, in both cases, it usually can illustrate that the destinations traffic parameter of the antenna is better, i.e., by user's use state
Or the influence of the factors such as placement status is smaller, then can define the use priority of the antenna higher.
Optionally, the current user information received is identified；
The mapping of use priority when according to preset user information and each antenna of multi-antenna terminal as primary antenna is closed
System, determines use priority when each antenna is as primary antenna when active user uses multi-antenna terminal；
The use priority of each antenna when multi-antenna terminal as primary antenna when is used to determine i-th day according to active user
The use priority of target primary antenna and current primary antenna after line switching.
The hand-held habit of the different terminals of different user can generate Different Effects to the destinations traffic parameter of different antennae, referring to
Fig. 6, Fig. 6 are status diagram when user uses multi-antenna terminal, when in terminal including three groups of antennas, such as can be by this
Three groups of antennas are separately positioned on the top, lower left and lower right at the terminal back side, respectively antenna 1, antenna 2 and antenna 3, when
User is then located at lower right antenna 3 when practising righthanded using terminal is blocked maximum by one's hands, the antenna 2 positioned at lower left
Certain influence of blocking may also be will receive, and the antenna 1 being located above terminal is not blocked by hand then completely, can guarantee best
Communication environment therefore the use priority of this three groups of antennas can be ranked up, i.e. 1 > antenna of antenna, 2 > antenna 3.This
According to the identification information of different user and the difference being arranged according to the habit of user's using terminal in terminal in embodiment
The use priority information of the antenna in orientation establishes corresponding relationship, and when different user is in using terminal, terminal receives user
Identification information such as fingerprint, sound etc., thus when directly obtaining this using terminal according to corresponding relationship each antenna using excellent
First grade, and then determine the use priority for completing the target primary antenna and current primary antenna that determine after preceding primary switching.
S503, the antenna switching threshold for obtaining the switching of i-th antenna；Current primary antenna after obtaining the switching of i-th antenna

Amount.Therefore after the completion of secondary antenna switching, if the use that the use priority of current primary antenna is higher than target primary antenna is preferential
Grade, should guarantee to reside in without being switched immediately on current primary antenna, i.e., current primary antenna is switched to target primary antenna as far as possible
It is more demanding, and by increase again carry out antenna switching antenna switching threshold can increase triggering antenna switching difficulty
Degree；If the use priority of current primary antenna is lower than the use priority of target primary antenna, the main day of target should be switched to as early as possible
Line gets on, i.e., the requirement that current primary antenna is switched to target primary antenna is lower, and carries out the day of antenna switching again by reducing
Line switching threshold can reduce the difficulty of triggering antenna switching.It can be corresponding preferential according to target primary antenna and current primary antenna
The difference of grade definition value configures antenna switching threshold when switching again to correspond to.In some embodiments, such as preceding primary

Be corresponding with an adjusting parameter all in accordance with certain mapping relations with absolute difference, as absolute difference collection is combined into 1,2,3,4,
5 }, the collection of corresponding adjusting parameter is combined into { 2,4,6,8,10 } dbm, i.e., it be corresponding adjusting parameter is 4dbm that difference, which is 2, if target
Primary antenna is greater than the use priority of current primary antenna, then antenna switching threshold when previous secondary antenna switches subtracts adjusting parameter
Difference be again carry out antenna switching antenna switching threshold, such as previous secondary antenna switching when antenna switching threshold be it is aforementioned
5dbm, adjusting parameter 4dbm, then again carry out antenna switching antenna switching threshold are as follows: 5dbm-4dbm=1dbm so that
It only needs to meet a lesser antenna switching threshold 1dbm when this time switching and can switch over, guarantee being switched to as quickly as possible
The high antenna of use priority gets on.Conversely, if target primary antenna is less than the use priority of current primary antenna, preceding primary day
Antenna switching threshold when line switches is the antenna switching threshold that carries out antenna switching again plus the sum of adjusting parameter, if such as
The use priority of target primary antenna and current primary antenna is respectively 2 and 4, then difference is -2, and difference equally corresponds to for -2
Adjusting parameter 4dbm, the antenna switching threshold 5dbm as the aforementioned when previous secondary antenna switches, then carry out antenna switching again
Antenna switching threshold are as follows: 5dbm+4dbm=9dbm, compared to it is preceding it is primary carry out antenna switching when antenna switching threshold increase compared with
It is more, increase the difficulty of triggering antenna switching so that resided on current primary antenna as far as possible so that the communication quality of antenna by
The influence of the factors such as user's use state or placement status is smaller.
S504, the destinations traffic parameter for obtaining multi-antenna terminal, antenna when being switched according to i+1 secondary antenna switch threshold
Value, judges whether to need to carry out i+1 secondary antenna switching, if so, thening follow the steps S505.This is continued to execute if it is not, then returning
Step S504.
S505, antenna switching is carried out.
The specific implementation process of the step can be with reference to the related narration in above-mentioned first embodiment, and details are not described herein.
By the implementation of the present embodiment, antenna switching threshold when being switched by previous secondary antenna calculate it is current again into
The antenna switching threshold of row antenna required satisfaction when switching, that is, when needing to carry out antenna switching again, even if current each antenna
Signal parameter meet initial antenna switching threshold, antenna switching will not be carried out, it is only full in the signal parameter of current each antenna
When antenna switching threshold when switching over again being calculated enough, antenna switching is just carried out again.As antenna switching is held
Antenna switching threshold keeps dynamic change while reforwarding row, has delayed antenna handover process, has solved existing multi-antenna terminal
Frequently operation antenna handoff algorithms carry out the problem that antenna switching causes power consumption larger, realize in antenna switching field to table tennis
The control of effect.Simultaneously by comparing the use priority and basis of current primary antenna and target primary antenna after preceding primary switching
Comparison result configures the antenna switching threshold switched again, so that main antenna is resided on the high antenna of priority as far as possible, makes
The communication quality of antenna is influenced smaller by user's use state or such as placement status other factors, thus take into account
The individual requirement that multi-antenna terminal switches antenna according to different use priorities, further enhance user uses body
