S302, when judging to meet the first trigger condition according to first messaging parameter, obtain for characterizing the communication Second messaging parameter of the current primary antenna performance of terminal.

For a better understanding, illustrated with reference to specific example：

When the first messaging parameter of acquisition only includes a messaging parameter, by a messaging parameter of the acquisition with it is corresponding The first parameter threshold be compared, when judging a messaging parameter and the first parameter threshold mismatch of the acquisition, it is determined that Meet the first trigger condition.

Such as a messaging parameter for acquisition is transmission signal power, now corresponding with transmission signal power first joins Number threshold value can be transmission signal power threshold P.Assuming that the transmission signal performance number obtained is P1, the transmitting can now be believed Number power P 1 judges whether P1 and P matches compared with corresponding transmission signal power threshold P, if it is determined that when mismatching, Then determine to meet the first trigger condition, on the contrary, if it is determined that when mismatching, it is determined that be unsatisfactory for the first trigger condition.

It should be noted that it is above-mentioned judge whether matching foundation can be：

So that the messaging parameter of acquisition is transmission signal power as an example, when the P1 values of acquisition are more than or equal to the transmitting of corresponding setting During signal power threshold value P, then it is considered that the transmission signal power P 1 mismatches with corresponding transmission signal power threshold P, by In when transmission signal performance number is bigger, it may indicate that antenna performance is poorer.Namely the messaging parameter that obtains and it is correspondingly arranged Messaging parameter threshold value is compared, when can more reflect the primary antenna poor-performing, then it is assumed that the messaging parameter of the acquisition is with being correspondingly arranged Messaging parameter threshold value mismatch, meet the first trigger condition；Conversely, if the messaging parameter obtained and the communication being correspondingly arranged are joined Number threshold value is compared, when can more reflect that the primary antenna performance is more excellent, then it is assumed that the messaging parameter of the acquisition and the communication being correspondingly arranged Parameter threshold matches, and is unsatisfactory for the first trigger condition.

Similarly, for maximum transmission power ratio value MTPL, when the MTPL numerical value of acquisition is more than or equal to the logical of corresponding setting When believing parameter threshold, then it is considered that messaging parameter MTPL mismatches with corresponding messaging parameter threshold value, because working as MTPL values When bigger, show that antenna performance is poorer.

For CQI, when the CQI numerical value of acquisition is less than the messaging parameter threshold value of corresponding setting, then it is considered that the communication Parameter CQI mismatches with corresponding messaging parameter threshold value, because when CQI value is bigger, shows that antenna performance is more excellent.

For SNR, when the SNR numerical value of acquisition is less than the messaging parameter threshold value of corresponding setting, then it is considered that the communication Parameter CQI mismatches with corresponding messaging parameter threshold value, because when SNR value is bigger, shows that antenna performance is more excellent.

For RSRQ, when the RSRQ numerical value of acquisition is less than the messaging parameter threshold value of corresponding setting, then it is considered that this is logical Letter parameter RSRQ mismatches with corresponding messaging parameter threshold value, because when RSRQ values are bigger, shows that antenna performance is more excellent.

, then it is considered that should when the EC/IO numerical value of acquisition is less than the messaging parameter threshold value of corresponding setting for EC/IO Messaging parameter EC/IO mismatches with corresponding messaging parameter threshold value, because when EC/IO values are bigger, shows that antenna performance is more excellent.

For RSSI, when the RSSI numerical value of acquisition is less than the messaging parameter threshold value of corresponding setting, then it is considered that this is logical Letter parameter RSSI mismatches with corresponding messaging parameter threshold value, because when RSSI value is bigger, shows that antenna performance is more excellent.

For RSCP, when the RSCP numerical value of acquisition is less than the messaging parameter threshold value of corresponding setting, then it is considered that this is logical Letter parameter RSCP mismatches with corresponding messaging parameter threshold value, because when RSCP values are bigger, shows that antenna performance is more excellent.

For Rx-AGC, when the Rx-AGC numerical value of acquisition is less than the messaging parameter threshold value of corresponding setting, then can consider Messaging parameter Rx-AGC mismatches with corresponding messaging parameter threshold value, because when Rx-AGC values are bigger, shows antenna performance It is more excellent.

It should be appreciated that the above-mentioned messaging parameter that the present embodiment is enumerated only only belongs to a kind of exemplary illustration, this hair Respective communication parameter that is bright to be not limited to above-mentioned messaging parameter, can also being applied under following new communication standard (such as 5G).

A messaging parameter (transmission signal power) for above-mentioned acquisition is uplink communication parameter, corresponding, at this A downlink communication is comprised at least when messaging parameter meets corresponding first trigger condition, in the second messaging parameter of acquisition to join Number.

When the first messaging parameter of acquisition includes at least two messaging parameters, by least two messaging parameters of the acquisition Respectively compared with messaging parameter threshold value corresponding to each messaging parameter, when comparative result be with corresponding messaging parameter threshold value not When the number for the messaging parameter matched somebody with somebody reaches default m, judge to meet the first trigger condition, wherein m is more than or equal to 1, is less than or equal to The number of the messaging parameter obtained.

For example, the first messaging parameter obtained includes (this when two channel quality indicator (CQI), signal to noise ratio snr messaging parameters In the first messaging parameter include a uplink communication parameter and a downlink communication parameter, now subsequently obtain second communication ginseng Number can be any at least one in upstream or downstream messaging parameter), pre-setting messaging parameter threshold value should include： Channel quality instruction threshold value (being assumed to be A) corresponding with channel quality instruction and snr threshold corresponding with signal to noise ratio are (false It is set to B).Further, the channel quality indicator (CQI) value (being assumed to be A1) of the acquisition and channel quality instruction A are compared Compared with if compared with A, A1 can more reflect that the primary antenna poor-performing, namely A1 are less than A, then judge that A1 and A is mismatched；Similarly, If judging signal to noise ratio (being assumed to be B1) and the snr threshold matching (namely B1 is more than B) obtained, B1 matches with B.Assuming that work as When predetermined number m is 1 in preceding first trigger condition, then it can determine that the channel quality instruction A1, the signal to noise ratio B1 that obtain are jointly full Foot first trigger condition, because both unmatched numbers are 1 (A1 is mismatched, B1 matchings), predetermined number m is reached.

It should be appreciated that predetermined number m should be more than or equal to 1, and less than or equal to the number of the messaging parameter obtained. When m is equal to the number of the messaging parameter obtained, that is to say each messaging parameter that needs obtain with corresponding messaging parameter threshold When value mismatches, just meet first trigger condition.

In some instances, when the first messaging parameter of acquisition includes at least two messaging parameters, will can also obtain At least two messaging parameter be normalized to obtain the first normalization numerical value, by first normalization numerical value with setting in advance The first normalized threshold put is compared, and is that the first normalization numerical value and the first normalized threshold mismatch in comparative result When, it is determined that meeting the first trigger condition.

For example, obtain the first messaging parameter for received signal strength indicator RSSI, received signal code power RSCP this two Individual downlink communication parameter, now the RSSI value (being assumed to be C1) of acquisition, RSCP values (being assumed to be D1) can be subjected to normalizing respectively Change is handled, it is assumed that respectively obtains C11 and D11, the C11 and D11 are combined into processing obtains the first normalization numerical value, by this First normalization numerical value is compared with the first normalized threshold, when judging to mismatch, it is determined that meeting the first trigger condition.

Can be specifically weighted sum processing with reference to processing, such as C11 weighted value is assigned as 0.8, D11 weighted value point With for 0.2, then the first obtained normalization numerical value can be：0.8C11+0.2D11.By value 0.8C11+0.2D11 and in advance If the first normalized threshold be compared, if 0.8C11+0.2D11 is less than first normalized threshold, judge satisfaction first Trigger condition.

The concrete mode of normalized can be：Assuming that the messaging parameter value obtained is RSSI, one can be preset admittedly Determine RSSI value, by the RSSI value got divided by the fixation RSSI value, obtain the normalization numerical value of the RSSI value of the acquisition.Such as The RSSI value of acquisition is -90dB, and default fixed RSSI value is 100dB, then the RSSI value for getting this is normalized After obtain：- 90dB/100d B=0.9.Illustrated above to be used only for exemplary illustration, the method for normalizing specifically used can be with According to actual conditions flexible Application.

The present embodiment also provides the side that a kind of the first messaging parameter according to acquisition judges whether to meet the first trigger condition Formula, in order to more fully understand, illustrated so that the first messaging parameter of acquisition only includes transmission signal power as an example, refer to figure 4, comprise the following steps：

S401, when predetermined time reaches, obtain the current primary antenna of communication terminal transmission signal power.

S402, by the transmission signal power of the acquisition compared with default multiple threshold ranges.

S403, the transmission signal power for judging the acquisition turn when first threshold scope (being greater than being equal to K1) is interior To step S404.

It should be appreciated that K1 should be more than K2 in this example, when the transmission signal power of acquisition is more than K1, say The poor-performing of the bright current primary antenna of terminal, step S404 is turned now to, namely determine to meet the first trigger condition, so as to trigger The handoff procedure of subsequent antenna, ensure the accuracy and validity of antenna switching.

S404, determine to meet the first trigger condition.

When S405, wait setting duration T1 are reached, step S401 is gone to.

When it is determined that meeting first trigger condition, so as to the antenna switching operations of triggering following, it can now wait Duration T1 to be set, the duration of setting can just re-execute to obtain current primary antenna hair after subsequent antenna switching is completed The process of signal power is penetrated, saves power consumption of terminal.

S406, judge that the transmission signal power of the acquisition (is, for example, less than K1, and be more than or equal in Second Threshold scope K2 when) interior, step S407 is gone to.

When the transmission signal power of the acquisition is in Second Threshold scope, it that is to say more than or equal to K2, less than K1, now Illustrate the performance of the primary antenna, compared with first threshold scope, there is some superiority, but may still need to further determine that, because This goes to step S407, counts the transmission signal power of current primary antenna continuously in the number of Second Threshold scope.

Current number of the transmission signal power in Second Threshold scope for continuously meeting the acquisition of S407, statistics.

It should be appreciated that it is not continuously full in Second Threshold scope, or currently in the transmission signal power currently obtained Foot, then should be clear by the number currently counted in number the first trigger condition of triggered satisfaction of Second Threshold scope Zero.

S408, judge whether the number reaches default first number y, in this way, go to step S404.

In the transmission signal power repeatedly measured continuously in the Second Threshold scope when, namely the number reaches default first During number, illustrate that the performance of the primary antenna is constantly in this poor situation.The influence of accidentalia is avoided, improves antenna switching Accuracy.Now determine to meet the first trigger condition, go to step S404.

If it should be appreciated that the number not up to presets first number, should persistently be judged.

When S409, wait setting duration T2 are reached, step S401 is gone to.

In the transmission signal power that step S406 judges to obtain in Second Threshold scope, and currently it is unsatisfactory for the first triggering bar During part, setting duration T2 is waited, then goes to the transmission signal power that step S401 obtains current primary antenna.

S410, when the transmission signal power for judging the acquisition is interior in the 3rd threshold range (being, for example, less than K2), go to Step S411.

When the transmission signal power of acquisition is in the 3rd threshold range, illustrate that the primary antenna performance is relatively preferable, the master Antenna performance can meet the normal use demand of user, it is not necessary to carry out antenna switching, go to step S411, it is determined that being unsatisfactory for First trigger condition, so as to not trigger antenna switching.Improve the accuracy of antenna switching.

S411, determination are unsatisfactory for the first trigger condition.

When S412, wait setting duration T3 reach, step S401 is gone to.

When the corresponding transmission signal power of acquisition is in default 3rd threshold range, illustrate current primary antenna performance compared with It is good, it is thus determined that being unsatisfactory for the first trigger condition, avoid performing follow-up antenna handoff procedure, ensure the accuracy of switching.This When, the respective performances parameter value of current primary antenna can reacquired when setting duration T3 reaches.

In this example, T1, T2, T3 value can flexibly be set according to actual conditions, could be arranged to it is identical, for example, 1 Second, 2 seconds etc., it can also be provided that it is different, for example, T3 can could be arranged to the longer time, because in acquisition relative to T2 When transmission signal power is in the 3rd threshold range, illustrate that current primary antenna performance is relatively preferable, because can be with proper extension The time interval of respective communication parameter is once obtained, reduces power consumption of terminal.

It should be appreciated that in this programme, when the first messaging parameter is unsatisfactory for first trigger condition, can not obtain Second messaging parameter, it now can directly determine not trigger antenna switching.Or meet the first triggering bar in the first messaging parameter Part, and when the second messaging parameter is unsatisfactory for corresponding second trigger condition, it can also directly determine not trigger antenna switching.

S303, according to second messaging parameter judge meet the second trigger condition when, it is determined that triggering antenna switching； When one messaging parameter comprises at least uplink communication parameter, the second messaging parameter comprises at least downlink communication parameter；In the first communication When parameter comprises at least downlink communication parameter, the second messaging parameter comprises at least uplink communication parameter；Antenna switching is included again It is determined that at least three groups of antennas and main transmitting-receiving path, auxiliary reception communicate between connected relation, so as to select new primary antenna, auxiliary Antenna and spare antenna.

In the present embodiment, the second messaging parameter of acquisition can only include a messaging parameter, now by acquisition this one Individual messaging parameter is judging the messaging parameter and the second parameter threshold of the acquisition compared with corresponding second parameter threshold When value mismatches, it is determined that meeting the second trigger condition.

The second messaging parameter obtained can also include at least two messaging parameters, now by least two of the acquisition Messaging parameter is respectively compared with messaging parameter threshold value corresponding to each messaging parameter, when comparative result is and corresponding messaging parameter When the number of the unmatched messaging parameter of threshold value reaches default n, judgement meets first trigger condition, and wherein n is more than etc. In 1, less than or equal to the number of the messaging parameter of acquisition.

The second messaging parameter obtained is when including at least two messaging parameters, can also be by by described at least two of acquisition Messaging parameter is normalized to obtain the second normalization numerical value, and numerical value and pre-set second are normalized by described second Normalized threshold is compared, and is that the described second normalization numerical value mismatches with second normalized threshold in comparative result When, it is determined that meeting the second trigger condition.

It should be appreciated that the above-mentioned process for being judged whether to meet the second trigger condition according to the second messaging parameter, and upper State and whether meet that the process of the first trigger condition is similar according to the first messaging parameter, will not be repeated here.

The present embodiment provides a kind of antenna handover trigger control method, applied to including main transmitting-receiving path, auxiliary receiving path And the communication terminal of at least three groups antennas, with main transmitting-receiving communication it is currently primary antenna in this at least three groups of antenna, when It is preceding connected with auxiliary receiving path supplemented by antenna, remaining is spare antenna, based on hardware architecture provided by the invention, is being monitored The connected relation between terminal each group antenna and main transmitting-receiving path, auxiliary receiving path is redefined when meeting to antenna trigger condition So as to select new primary antenna, auxiliary antenna and spare antenna, the switching of antenna is completed, namely the work role of antenna is movable State change, it can be adjusted flexibly, avoided because antenna performance deterioration causes to go offline or the situation of call drop, lifting according to current demand Consumer's Experience；In addition, the present invention is judged whether completely by obtaining the first messaging parameter of the current primary antenna of communication terminal first The first trigger condition of foot, and the second messaging parameter of the primary antenna is obtained when meeting first trigger condition again, wherein first When communication antenna comprises at least uplink communication parameter, the second messaging parameter comprises at least downlink communication parameter；In the first communication ginseng When number comprises at least downlink communication parameter, the second messaging parameter comprises at least uplink communication parameter；With reference to the up logical of the acquisition Letter parameter and downlink communication parameter are assessed the performance of current primary antenna, so as to be determined whether to trigger day according to assessment result Line switches, namely based on two different dimensions (uplink communication parameter and downlink communication parameter) and different sequential messaging parameters come The foundation that the performance of current primary antenna is good and bad, switches as triggering antenna is assessed, therefore can ensure to trigger the standard of antenna switching True property and reliability, as long as while when meeting respective antenna trigger condition, can just perform and follow-up redefine antenna role Process, therefore antenna can be avoided frequently to switch, save resource and power consumption, further lift the satisfaction of Consumer's Experience Degree.
