In the present embodiment, parameter decision threshold value corresponding with first object messaging parameter is provided with, is being calculated two After two differences, each same parameter decision threshold of difference two-by-two can be compared, determined whether thereafter according to comparative result Into switching the stage to be sentenced.

In the present embodiment, switch stage entry condition to be sentenced could be arranged to：Exist in difference two-by-two and be more than parameter The situation of decision threshold, judgement, which enters, switches the stage to be sentenced；Or it could be arranged to：It is not present in difference two-by-two and sentences more than parameter Determine the situation of threshold value, judgement, which enters, switches the stage to be sentenced.It should be understood that foregoing two ways is only capable of selecting one and is configured.

It is worth noting that, if the first object messaging parameter got only can characterize antenna communication comprising one kind The messaging parameter of energy, then when calculating the difference two-by-two of each antenna first object messaging parameter, it can only will obtain for the communication The difference two-by-two of parameter, so, determine whether that satisfaction switches the stage to be sentenced in the difference two-by-two based on first object messaging parameter During entry condition, it is only necessary to be compared each difference two-by-two with default parameter decision threshold value, you can draw a conclusion.But For in the case of the first object messaging parameter got includes two or more messaging parameters, how this is based on Parameter decision threshold value is made decisions, and such two kinds of solutions are set forth below that (entry condition is arranged in following scheme Exist two-by-two in difference and illustrated in case of being more than parameter decision threshold value, is arranged to for entry condition in difference two-by-two In be not present more than parameter decision threshold value situation, overall process is consistent with following manner, differs only in and parameter decision threshold The manner of comparison of value is different)：

Scheme one, for the different communication parameter in first object messaging parameter, different parameter decision thresholds is set respectively Value.To difference judges two-by-two when, for the difference two-by-two of different communication parameter, using different parameter decision thresholds Value is compared.For example, being directed to antenna A1 and A2, the first object messaging parameter got includes two messaging parameters of x and y, Then one parameter decision threshold value can be set for x and y respectively.It is poor two-by-two under x parameter that antenna A1 and A2 is now calculated respectively Value, and the difference two-by-two under y parameters.Again respectively by the parameter decision for messaging parameter x threshold value two-by-two with messaging parameter x Threshold value is compared, and will be compared for messaging parameter y threshold value two-by-two with messaging parameter y parameter decision threshold value.

For a certain messaging parameter in first object messaging parameter, if any one in each difference two-by-two is more than ginseng Number decision threshold, you can judge that the messaging parameter meets to switch stage entry condition to be sentenced.If one is all unsatisfactory for, judge The messaging parameter is unsatisfactory for switching stage entry condition to be sentenced.Certainly, determine whether a messaging parameter meets to switch rank to be sentenced During section entry condition, other conditions can also be passed through.Such as, for being more than parameter decision threshold in each difference two-by-two of the messaging parameter Whether the number of value reaches predetermined number.For example, among multi-antenna terminal X, it is desirable to for the difference two-by-two of a certain messaging parameter, There must be 2 to reach parameter decision threshold value, just can be determined that the messaging parameter meets to switch stage entry condition to be sentenced, if then Among multi-antenna terminal X, there is 3 antennas, then must have two two-by-two difference be more than or equal to parameter decision threshold value.For Whether other messaging parameter meets to switch when stage entry condition is sentenced, and in this way, repeats no more here.

After whether meeting that the judgement for switching stage entry condition to be sentenced is completed to each messaging parameter, it is also necessary to further Whether the number for judging to reach the messaging parameter for switching stage entry condition to be sentenced reaches predetermined number, if so, really judging to meet Switch stage entry condition to be sentenced, otherwise, it is determined that being unsatisfactory for switching stage entry condition to be sentenced.For example it is assumed that predetermined number is 1, and first object messaging parameter includes 3 messaging parameters, then waits to sentence when any one satisfaction in this 3 messaging parameters switches During stage entry condition, you can judge that antenna performance meets the judgment condition when the leading decision stage.

Scheme two：One nondimensional parameter decision threshold value is only set.Here illustrated by taking certain two antenna as an example：Can Selection of land, dimension first is carried out to each difference two-by-two of this two antennas and handles to obtain corresponding standard deviation, then calculate two days The mean difference of each standard deviation of line.

Hereafter when relatively, by each antenna two-by-two between mean difference with adjudicate the stage phase threshold compared with, when Any one in each mean difference is more than parameter decision threshold value, or when each mean difference reaches more than the ratio of parameter decision threshold value During to preset ratio, judge that satisfaction switches stage entry condition to be sentenced.

Here to going dimension processing simply to be introduced by taking received signal strength and received signal quality as an example：For receiving Signal intensity, determine its maximum P in antenna practical application_MAX.Similarly, for signal quality, determine that it is likely to be breached Maximum Q_MAX.It is assumed that the difference two-by-two of two antennas A1 and A2 of certain being calculated current received signal strength is P, connect The difference two-by-two for receiving signal quality is Q, then the standard deviation point obtained after dimension processing is carried out for the two messaging parameters Wei not P/P_MAXAnd Q/Q_MAX.So the mean difference between this two antenna standard values is (P/P_MAX+Q/Q_MAX)/2.It should be understood that , can also be carried out in the following manner when calculating mean difference：It is assumed that two antennas A1 and A2 of certain got are current Received signal strength be respectively P1 and P2, received signal quality is respectively Q1 and Q2, then is carried out for the two messaging parameters The obtained standard value P1/P of antenna A1 received signal strengths is removed after dimension processing_MAX, the standard value Q1/ of received signal quality Q_MAX；The standard value P2/P of antenna A2 received signal strengths_MAX, the standard value Q2/Q of received signal quality_MAX.This two antenna marks Mean difference between quasi- value is (∣ P1/P_MAX-P2/P_MAX∣+∣Q1/Q_MAX-Q2/Q_MAX∣)/2。

Certainly, among some other example of the present embodiment, can be counted using modes such as weighted average or arithmetic averages Calculate mean difference.Alternatively, it is also possible to without calculate mean difference, for example, when phase threshold be for standard deviation sum set When, it is possible to directly by (P/P_MAX+Q/Q_MAX) be compared with phase threshold.

It should be appreciated that the method for going dimension to handle has a lot, in addition to the mode of above-mentioned example, " phase can also be used To changing processing method ", " function processing method ", " extreme value method ", " standardized method ", " method for normalizing " etc. carry out Dimension is gone to handle.In fact, said process is the mode that dimension is gone in a kind of simple normalization.

It should be appreciated that when carrying out dimension and handling, some messaging parameters belong to " direct index ", and its value is higher, then It is better to characterize antenna performance, such as received signal quality, received signal strength etc..But some messaging parameters then belong to " negative to refer to Mark ", such as MPTL (Maximum transmit power level, maximum transmission power in the bit error rate, uplink communication parameter Ratio value) etc., its value is smaller, then representative antennas performance is more excellent.It is average calculating for " positive and negative index " be present simultaneously The messaging parameter for direct index and negative index is needed during difference to be needed to be considered.For example it is assumed that certain being calculated The standard deviation of two antenna received signal strengths is P11, and the standard deviation of the bit error rate is J11, then can use Arithmetic Expressions Using (P11-J11)/2 mean difference is obtained.Now mean difference is bigger, that is, it is more excellent to characterize antenna performance.It is it should be appreciated that foregoing Calculation is only a kind of feasible simple examples, does not represent the present invention and is only capable of using this kind of calculation pair while exists " just The situation of negative index " is handled.In fact, pair can also be existed simultaneously using processing modes such as " relative processing methods " The situation of " positive and negative index " is handled.

It should be appreciated that in a kind of implementation of the present embodiment, first object messaging parameter can also judged Difference two-by-two be unsatisfactory for switching when stage entry condition is sentenced, directly judge whether antenna needs to switch.Specifically：

Can be by the difference two-by-two of first object messaging parameter compared with the default first direct switching condition；If the The difference two-by-two of one destinations traffic parameter meets the first direct switching condition, then judges to need to carry out antenna switching.

In aforesaid way, the first direct switching threshold can be set, and will respectively difference and the first direct switching threshold two-by-two Value is compared, if each difference two-by-two is more than the first direct switching threshold, that is, judges to meet the first direct switching condition, it is necessary to enter Row antenna switches.It should be appreciated that in this fashion, if first object messaging parameter includes two or more lead to Believe parameter, can refer to such scheme one and the processing mode described in scheme two is handled, it is not described in detail herein.

S304：When the difference two-by-two of first object messaging parameter meets to switch when stage entry condition is sentenced, into switching Stage to be sentenced so as to decide whether to need carry out antenna switching；

Specifically, the second of each antenna corresponding with switching the stage to be sentenced can be obtained switching stage multi-antenna terminal to be sentenced Destinations traffic parameter, and calculate the difference two-by-two of the second destinations traffic parameter of at least three antennas；Judge that the second target is led to again Whether the difference two-by-two of letter parameter meets default antenna switching condition；If satisfied, judge to need to carry out antenna switching.

It should be appreciated that it can also be descending logical that the second destinations traffic parameter got, which can be uplink communication parameter, Believe parameter.It will be clear that for the number of messaging parameter in the second destinations traffic parameter for getting, in the present embodiment not Specifically limited, can be one or two and more than.It should be appreciated that either uplink communication parameter is also It is downlink communication parameter, the performance of antenna can be characterized.Therefore the second destinations traffic parameter can characterize the performance of antenna.Also It should be appreciated that the second destinations traffic parameter got in the present embodiment can be identical with first object messaging parameter, Can also be different.

In the present embodiment, switching the stage to be sentenced can be divided into the progress antenna switching condition judgement of the second messaging parameter In N number of judgement stage, judge whether antenna switching condition meets further according to the court verdict in N number of judgement stage.Wherein N value More than or equal to 1.As for specific value, can by the designer of multi-antenna terminal or by user according to oneself to power consumption, property The requirement of energy etc. the either self-defined setting such as hobby.

In the present embodiment, at least two different operating process in each judgement stage be present：

Operating process one：It is shown in Figure 4, used by each judgement stage operating process include：

S401：Obtain the second destinations traffic parameter of each antenna；

It should be appreciated that among each example of the present embodiment, the second destinations traffic for being obtained in each judgement stage Parameter can be identical, for example, MTPL and received signal quality can be obtained in each judgement stage；In each judgement stage Second destinations traffic parameter of middle acquisition can also be incomplete same, for example, can be obtained in the first judgement stage MTPL and received signal quality；MTPL and received signal strength are obtained in the second judgement stage.

S402：Calculate the difference two-by-two of the second destinations traffic parameter of each antenna；

It should be appreciated that the mode for calculating the difference two-by-two of the second destinations traffic parameter of each antenna calculates respectively with foregoing The mode of the difference two-by-two of the first object messaging parameter of antenna is identical, therefore will not be repeated here.

S403：Phase threshold based on the judgement stage determines whether result of calculation meets judgement corresponding to the judgement stage Condition；If go to step S404；Otherwise step S407 is gone to.

In the present embodiment, corresponding phase threshold is both provided with for each judgement stage, it is poor two-by-two being calculated After value, each difference two-by-two can be compared with phase threshold, if at least one difference two-by-two be present is more than stage threshold Value, then show to determine that each current performance of antenna has reached a certain distance according to comparative result, so as to illustrate each day The gap of performance has met the necessity for when the judgment condition in leading decision stage, existing and carrying out antenna switching between line；It is no Then, illustrate that the performance of current each antenna is similar, do not switch needs, so, can directly judge, which need not carry out antenna, cuts Change, exit antenna switching flow.

It is similar with step S303, if the second destinations traffic parameter got only can characterize antenna comprising one kind The messaging parameter of communication performance, then when calculating the difference two-by-two of each the second destinations traffic of antenna parameter, it can only will be directed to The difference two-by-two of the messaging parameter, so, when judging whether to meet judgment condition corresponding to the judgement stage, it is only necessary to will be each Individual difference two-by-two with phase threshold be compared i.e. it could be assumed that.Identical, if in the second destinations traffic ginseng got When number includes two or more messaging parameters, it can be joined come the mode made decisions to result of calculation based on phase threshold Such scheme one and the mode described in scheme two are examined, is no longer carefully stated here.

S404：Judge whether the presently described judgement stage is last judgement stage；If go to step S405；It is no Then, step S406 is gone to；

, it is necessary to judge this current when judging to meet the judgment condition in judgement stage among a judgement stage Whether the judgement stage is last judgement stage.If it is not, next judgement stage also be present in explanation, therefore, when Preceding antenna performance also needs to do further assessment, therefore, into S406.If it is, explanation antenna performance is completely logical The judgement in N number of judgement stage has been crossed, so, it is possible to determine that currently antenna switching condition is met, it is necessary to carry out antenna switching, because This can enter S405.

S405：Judgement needs to carry out antenna switching.

After judging to need to carry out antenna switching, it is possible to enter the process for reselecting primary antenna and auxiliary antenna.

S406：Into next judgement stage.

It should be appreciated that respectively the flow in judgement stage is similar in the present embodiment, therefore here no longer to other judgement stages Process be introduced.

S407：Judgement need not carry out antenna switching.

When being judged to that antenna switching need not be carried out, i.e., directly exit antenna switching flow.

Operating process two：It is shown in Figure 5, used by each judgement stage operating process include：

S501：Obtain the second destinations traffic parameter of each antenna；

Likewise, the second destinations traffic parameter obtained in each judgement stage can be identical or endless Exactly the same.

S502：Calculate the difference two-by-two of the second destinations traffic parameter of each antenna；

It should be appreciated that the mode for calculating the difference two-by-two of the second destinations traffic parameter of each antenna calculates respectively with foregoing The mode of the difference two-by-two of the first object messaging parameter of antenna is identical, therefore will not be repeated here.

S503：The difference two-by-two of each second destinations traffic parameter is compared with the phase threshold in judgement stage；According to Comparative result judges whether to meet to work as the second direct switching condition corresponding to the leading decision stage；If satisfied, go to step S504；It is no Then, step S505 is gone to.

In the present embodiment, corresponding phase threshold is both provided with for each judgement stage, it is poor two-by-two being calculated After value, each difference two-by-two can be compared with when phase threshold corresponding to the leading decision stage, and according to comparative result Judge whether to meet to work as direct switching condition corresponding to the leading decision stage, that is, determine whether the current performance of each antenna has reached Very big gap.If meeting the second direct switching condition, the gap for illustrating performance between each antenna it is very big, it is necessary to Antenna switching is carried out at once.

It is similar with step S303, if the second destinations traffic parameter got only can characterize antenna comprising one kind The messaging parameter of communication performance, then when calculating the difference two-by-two of each the second destinations traffic of antenna parameter, it can only will be directed to The difference two-by-two of the messaging parameter, so, when judging whether to meet judgment condition corresponding to the judgement stage, it is only necessary to will be each Individual difference two-by-two with phase threshold be compared i.e. it could be assumed that.Identical, if in the second destinations traffic ginseng got When number includes two or more messaging parameters, it can be joined come the mode made decisions to result of calculation based on phase threshold Such scheme one and the mode described in scheme two are examined, is no longer carefully stated here.

S504：Directly judge to need to carry out antenna switching.

After judging to need to carry out antenna switching, it is possible to enter the process for reselecting primary antenna and auxiliary antenna.

S505：Judge whether to need to enter next judgement stage；If so, go to step S506；Otherwise, step is gone to S507。

In the present embodiment, judging whether to need a kind of concrete mode into next stage is：Judge currently this Whether the individual judgement stage is last judgement stage, that is, a judgement stage in the presence of judging whether also.If it is not, say Bright can also be done to current antenna performance is assessed again, therefore, into S506.If it is, explanation antenna performance has been entered Go the judgement in continuous N number of judgement stage, and antenna not can determine that antenna needs in the judgement in this continuous N number of judgement stage Switching.So, it is possible to determine that currently it is unsatisfactory for antenna switching condition, it is not necessary to carry out antenna switching, therefore S507 can be entered.

In the present embodiment, can also be further to when leading decision rank after next judgement stage is judged whether The difference two-by-two for the messaging parameter that section obtains switches over the judgement of threshold value, specifically：By when the leading decision stage obtain it is logical The difference two-by-two of parameter is believed compared with default handoff threshold value, if comparative result meets when corresponding to the leading decision stage Next judgement stage entry condition, i.e., into next judgement stage；Otherwise, directly judge that antenna switching need not be carried out.For example, If when the leading decision stage only obtains a kind of messaging parameter, by each difference two-by-two of the messaging parameter obtained when the leading decision stage Compared with default handoff threshold value, it is more than default handoff threshold value if there is at least one difference two-by-two, then sentences Surely enter next judgement stage, otherwise, directly judge that antenna switching need not be carried out.It should be appreciated that for working as leading decision Stage only obtains the situation of two or more messaging parameter, can be that different communication parameter sets different cut respectively Threshold value is changed, then handoff threshold value corresponding with the messaging parameter is carried out respectively by each difference two-by-two corresponding to different communication parameter Compare, be more than preset requirement in the number that the messaging parameter that at least one difference two-by-two is more than corresponding handoff threshold value be present During number, judge to enter next judgement stage；Or the difference two-by-two of different communication parameter two antennas is carried out at dimension Manage and mean difference is calculated, then the handoff threshold by each mean difference default mean difference corresponding with working as the leading decision stage Value is compared, and when at least one mean difference be present more than corresponding handoff threshold value, judges to enter next judgement stage.

It should be appreciated that in each judgement stage, the handoff threshold value of setting should be less than the phase threshold set. In the present embodiment, phase threshold and handoff threshold value can be preset by engineer according to the practical situations of antenna. Simultaneously it should be appreciated that in the different judgement stages, can also be set even with the handoff threshold value of same messaging parameter Difference.

S506：Into next judgement stage.

It should be appreciated that respectively the flow in judgement stage is similar in the present embodiment, therefore here no longer to other judgement stages Process be introduced.

S507：Judgement need not carry out antenna switching.

When being judged to that antenna switching need not be carried out, i.e., directly exit antenna switching flow.

It is worth noting that, in above two operating process, each phase threshold for adjudicating the stage can with it is equal can also It is not completely equivalent.The phase threshold in each judgement stage, which is not completely equivalent, refers at least two judgement ranks in each judgement stage be present The phase threshold of section is unequal.In the present embodiment, respectively the phase threshold in judgement stage can gradually successively decrease, namely preceding sentence Certainly the phase threshold in stage is more than the phase threshold in the rear judgement stage.Such as the advanced judgement of condition in some multi-antenna terminal It is central, including 3 judgement stages, wherein the phase threshold in the first judgement stage to the 3rd judgement stage is respectively D1, D2 and D3, These three phase thresholds meet D1>D2>D3 relation.

It should be appreciated that the main of the advanced judgement of condition is carried out to each antenna using each judgement stage in the present embodiment Purpose is to carry out more objective performance evaluation to each antenna, so as to ensure the validity and accuracy of antenna switching.Simultaneously It should be appreciated that for uplink communication parameter, what it was mainly characterized is sending performance of the antenna to signal, and under For row messaging parameter, what it was mainly characterized is receptivity of the antenna to signal.Therefore, antenna is carried out to be further ensured that Performance evaluation it is objective, comprehensive, obtain each step of first object messaging parameter and the second destinations traffic parameter in the present embodiment In rapid, it may be set in all messaging parameters got and comprise at least a kind of uplink communication parameter and a kind of downlink communication ginseng Number.I.e.：In the present embodiment, comprised at least in the first object messaging parameter got and the second destinations traffic parameter in one kind Row messaging parameter and a kind of downlink communication parameter.

In the present embodiment, if N is more than or equal to 2, latent period can be set to each judgement stage.It is appreciated that It is that the time span undergone during antenna is bigger, and assessment result is more objective if assessed.So the one of the present embodiment Among a little examples, the undergone time is adjudicated in order to which the condition of extending is advanced, can be set between the two neighboring judgement stage etc. The cycle is treated, by the time-consuming of latent period, the influence of accidentalia can be excluded by the time of abundance.But latent period Duration the longer the better yet, because if latent period is oversize, then arriving causes whole antenna switch step long, Ke Neng Consumer's Experience is influenceed in some cases.For example, the current primary antenna performance of terminal is excessively poor, the performance of spare antenna can but expire substantially Sufficient user's request, user just converse in this case, then are badly in need of carrying out antenna switching.But the latent period set is long, this Antenna can be caused to be switched and determined time-consuming especially long, so as to cause call experience of the user within a very long time all bad.Cause Setting for this latent period should the compatible influence considered to assessment result and Consumer's Experience.In the present embodiment, latent period Duration can be pre-set by Terminal Design personnel, or can also be set by User Defined.In the present embodiment, wait Between the value in cycle could be arranged to 0.1s-10s, such as it could be arranged to 1s.

Due to not fully being bound between each judgement stage, therefore, latent period among each judgement stage can with equal, It can also be not completely equivalent.For example, the latent period for respectively adjudicating the stage is 3s, or the latent period in the first judgement stage is 3s, and the latent period in the second judgement stage is only 2s, this is also feasible.Among some examples of the present embodiment, respectively sentence Certainly the latent period in stage gradually successively decreases.In addition, the different demands of multi-antenna terminal radio-frequency enabled can be corresponded to for user Different latent periods is set, for example, in user's communication and online etc. to that under the scene of radio-frequency enabled heavy dependence, can incite somebody to action Latent period sets shorter, and for other scenes insensitive to data transmit-receive, then it can increase the length of latent period The stage is spent, can not have to set latent period.It should be appreciated that when judging to need to carry out antenna switching, Ke Yizhi Tap into the process into day line options.

In the present embodiment, determine that each antenna performance meets the judgement bar in this judgement stage in a judgement stage Part, and determine when also needing to enter next judgement stage, it is introduced into when the latent period in leading decision stage, when latent period terminates Afterwards, next judgement stage is entered back into.In this way, the undergone duration of the advanced judgement of further extension condition, so as to right The performance of each antenna performance in a longer period of time is evaluated, and draws more fully conclusion, is further lifted antenna performance and is commented Estimate the accuracy of conclusion.

It should be appreciated that an initial latency can be set into before switching the stage to be sentenced in the present embodiment In the cycle, switch it is determined that needing to enter when the stage is sentenced, first waited according to the duration set by the initial latency cycle, then obtain Take the second destinations traffic parameter.This can also equally exclude the influence of accidentalia, be further ensured that the validity of antenna switching And accuracy.In the present embodiment, the duration in initial latency cycle can also be pre-set or by user by Terminal Design personnel Self-defined setting.

To sum up, in the present embodiment, respectively there are 4 kinds of facilities in the phase threshold in judgement stage and latent period：It is i.e. N number of The phase threshold in judgement stage is equal, and the latent period in each judgement stage is equal；The phase threshold in N number of judgement stage is equal, And the latent period in each judgement stage is unequal；The phase threshold in N number of judgement stage is unequal, and the wait week in each judgement stage Phase is equal；The phase threshold in N number of judgement stage is unequal, and the latent period in each judgement stage is also unequal.

S305：When judging to need to carry out antenna switching, at least three antennas and main transmitting-receiving path, auxiliary reception are redefined Connected relation between path is so as to selecting new primary antenna, auxiliary antenna and spare antenna.

When primary antenna, auxiliary antenna is reselected, it can be carried out according to based on the messaging parameter got before Selection, can also reacquire current messaging parameter, then the performance ranking further according to each antenna under the messaging parameter, select Select best performance one is used as primary antenna, the main transmitting-receiving communication with the multi-antenna terminal, selects one of performance suboptimum As auxiliary antenna, connected with the auxiliary receiving path of the multi-antenna terminal, using remaining antenna as spare antenna.

Specifically, when being selected based on the messaging parameter got before, following two selection modes at least be present：

One：Select one kind to be used as critical parameter from each messaging parameter got before, and will get before The critical parameter of each antenna be compared, the optimal antenna of critical parameter is defined as new primary antenna and replaces former primary antenna With main transmitting-receiving communication, the antenna of critical parameter suboptimum is defined as new auxiliary antenna and replaces former auxiliary antenna to lead to auxiliary receive Road connects, and remaining antenna is defined as spare antenna.

For example, setting selection MTPL as critical parameter, provided with three antennas A1, A2 and A3, A1, A2 and A3 are got before MTPL be respectively M1, M2 and M3, M1, M2 and M3 are compared, if M1>M2>M3, then A1 is selected to connect with main transmitting-receiving path It is logical, select A2 to be connected with auxiliary receiving path, A3 is defined as spare antenna.

Secondly：All messaging parameters corresponding to each antenna are calculated respectively according to default computation rule, distinguished Critical parameter corresponding with each antenna；The critical parameter of each antenna got is compared again, critical parameter is optimal Antenna is defined as new primary antenna and replaces former primary antenna and main transmitting-receiving communication, and the antenna of critical parameter suboptimum is defined as The new former auxiliary antenna of auxiliary antenna and replacement connects with auxiliary receiving path, and remaining antenna is defined as spare antenna.

For example, being provided with three antennas A1, A2 and A3, getting messaging parameter before has transmission signal power and reception signal Intensity, if the transmission signal power got before A1, A2 and A3 is respectively P1, P2, P3, the reception signal got before is strong Degree is respectively Q1, Q2, Q3.Then P1, P2, P3 and Q1, Q2, Q3 are carried out respectively dimension handle to obtain P11, P21, P31 and Q11、Q21、Q31.Parameter value after going dimension to handle corresponding to each antenna is summed (it should be appreciated that can also be here Averaged, multiplication, weighted sum etc. calculate, and are not especially limited in the present embodiment), obtain A1 critical parameter a= P11+Q11, A2 critical parameter b=P21+Q21, A3 critical parameter c=P31+Q31.A, b, c are compared again, if a>b >C, then A1 and main transmitting-receiving communication are selected, select A2 to be connected with auxiliary receiving path, A3 is defined as spare antenna.

When the current messaging parameter of reacquisition is selected, critical parameter can be preset as any or a variety of tools The messaging parameter of body.

When it is a kind of messaging parameter to preset critical parameter, critical parameter can be obtained and be compared, by critical parameter Optimal antenna is defined as new primary antenna and replaces former primary antenna and main transmitting-receiving communication, by the antenna of critical parameter suboptimum It is defined as new auxiliary antenna and replaces former auxiliary antenna to be connected with auxiliary receiving path, remaining antenna is defined as spare antenna.

When it is two or more messaging parameter to preset critical parameter, its selection mode with it is above-mentioned be based on before Selection mode is similar in second when the messaging parameter got is selected, can be laggard in the messaging parameter for getting each antenna Row goes dimensionization to handle, and a new parameter is calculated, by compare the new parameter determine primary antenna, auxiliary antenna and Spare antenna.

It should be appreciated that each step of the antenna switching method in the present embodiment can be by terminal as shown in Figure 1 100 independently realize, specifically, each of above-mentioned antenna switching method can be achieved by being stored in the memory 109 of terminal 100 The processing routine of individual step, the processing routine is performed by processor 110 antenna is made whether to need progress antenna to cut to realize The judgement changed；Simultaneous processor 110 also realizes the control performance when judging to need to carry out antenna switching after performing the processing routine An optimal antenna and main transmitting-receiving communication, an antenna of control performance suboptimum connect with auxiliary receiving path.

Meanwhile in the present embodiment, a kind of computer-readable recording medium is also provided, such as floppy disk, CD, hard disk, flash memory, U Disk, CF cards, SD card, mmc card etc., be stored with the computer-readable recording medium realize above-mentioned each step one or Multiple programs, this one or more program can be by one or more computing devices, so as to realize above-mentioned antenna switching side Each step of method.

The antenna switching method and computer-readable recording medium that the present embodiment provides, first obtain the first object of each antenna Messaging parameter, and antenna is carried out to determine a need for entering on the difference two-by-two of first object messaging parameter according to each antenna Switching switches the stage to be sentenced, and is switching the second destinations traffic parameter of stage acquisition to be sentenced, further according to each antenna on second The difference two-by-two of destinations traffic parameter come determine a need for carry out antenna switching.When judging to need to carry out antenna switching, then The connected relation between each antenna and main transmitting-receiving path, auxiliary receiving path is redefined so as to select new primary antenna, auxiliary day Line and spare antenna.So due to that before determining the need for reselecting main and auxiliary antenna, can have sequential pass in the presence of two In the stage of system, the performance of nature can be done in the two stages and assessed at least twice, so compared to the side disposably assessed Formula, antenna performance not exclusively simply undergoes to be judged at least twice, moreover, importantly, can be to each antenna in bar Overall performance in during the advanced judgement of part carries out objective comprehensive evaluation, excludes influence of the accidentalia to antenna performance, from And make it that follow-up switching is reliable and effective, each antenna for ensureing to participate in work after switching possesses really stable superperformance, So as to lift Consumer's Experience.

Second embodiment

The present embodiment is on the basis of first embodiment, is equal to 2 with N, first object messaging parameter is MTPL, the second mesh In case of messaging parameter is marked as received signal strength, present invention work is further illustrated.

Referring to Fig. 6, Fig. 6 is a kind of specific antenna handoff procedure schematic diagram that second embodiment of the invention provides, if institute It is triantennary terminal to state multi-antenna terminal.Three antennas in terminal are designated as respectively：Antenna A1, antenna A2 and antenna A3.If The initial latency cycle is T1, and latent period corresponding to first judgement stage is T2.Antenna handoff procedure includes：

S601：Obtain MTPL corresponding to each antenna in multi-antenna terminal；

If now getting antenna A1, MTPL corresponding to antenna A2 and antenna A3 is respectively M1, M2 and M3.

S602：The difference two-by-two of the MTPL of each antenna in multi-antenna terminal is calculated；

Now be calculated the Zhi ∣ of Cha two-by-two M11-M12 ∣, antenna A1 and antenna A3 between antenna A1 and antenna A2 it Between the Zhi ∣ M11-M13 ∣ of Cha two-by-two, and the Zhi ∣ M12-M13 of Cha two-by-two ∣ between antenna A2 and antenna A3.
