Specific scene or demand are flexibly set, in the hope of reaching best communication efficiency or making its shadow by environmental change
Sound is smaller.
It should be appreciated that primary antenna can receive extraneous send to the data message of this terminal and outwards in the present embodiment
Transmission signal, and auxiliary antenna can be used for auxiliary reception signal.It should be noted that each group of the communication terminal in the present embodiment
Antenna should be respectively provided with transmitting and reception signal function, but only in main working condition (namely with it is main transmitting-receiving path connect
Logical antenna) primary antenna can just carry out the transmitting-receiving of signal, and in auxiliary working condition (namely the day connected with auxiliary receiving path
Line) auxiliary antenna only carry out the reception of signal, and the spare antenna in idle condition need not then carry out the reception of signal, also not
The transmitting of signal must be carried out.And because spare antenna is not both with main transmitting-receiving communication, also do not connected with auxiliary receiving path, therefore
The reception or transmitting of signal can not be carried out.Namely the working condition of each antenna is by the company with main transmitting-receiving path, auxiliary receiving path
Understanding and considerate condition determines.
The signal performance parameter for needing exist for how obtaining communication terminal primary antenna illustrates, the master in the present embodiment
Electric wave signal may be converted to high frequency electrical signal, the electricity by antenna after outer signals are received by electromagnetic induction
Signal will flow to communication terminal and carry out signal transacting, and the information for handling to obtain may can be obtained and be used by communication terminal,
, wherein it is desired to it is noted that communication terminal can acquire the performance parameter of current primary antenna in this process：Receive letter
Number intensity and received signal quality, but the mode for obtaining performance parameter can be real-time, for example conversing or networking
During, user can wish the progress that the communication of communication terminal can be smooth, then communication equipment can be obtained constantly always to be come
The performance data of the electric wave signal of self-consistent antenna, and these performance datas are assessed and analyzed.If in addition, this communication terminal
It is constantly in the state for the parameter for obtaining primary antenna in real time, it will increase the power consumption of this communication terminal, shorten making for communication terminal
Use duration.
This communication terminal can obtain the performance parameter of primary antenna again with separated in time, for example can be spaced 5s and obtain again
The received signal strength and received signal quality of the primary antenna of communication terminal are taken, further, if communication terminal interval acquiring master
When the received signal strength and received signal quality of antenna, the performance parameter of the primary antenna obtained every time in certain time be all compared with
Alright, certain extension can be made by obtaining the interval time of aerial signal, for example interval extends 1s, 2s etc., so can be more
The effective electricity for saving communication terminal, so as to extend the use duration of communication terminal.It should be noted that it is above-mentioned enumerate between
Understand every duration just for the sake of convenient.
In the present embodiment, communication terminal mainly obtains current received signal strength and received signal quality the two signals
Parameter is used for judging the quality of current primary antenna performance.
In the present embodiment, GSM (Global System for Mobile are currently in the communication terminal
Communication, global system for mobile communications) under network formats when, received signal strength and received signal quality the two
Signal parameter is respectively received signal strength indicator (RSSI, Received Signal Strength Indication) and letter
Make an uproar than (SNR, SIGNAL-NOISE RATIO).
S302：The performance of the current primary antenna is carried out with reference to the received signal strength and the received signal quality
Assess.
Here how to judge communication terminal that primary antenna performance quality illustrates, and acquires currently in communication terminal again
After the two signal performance parameters of the received signal strength and received signal quality of primary antenna, communication terminal can be to current main day
The performance of line is assessed, the received signal strength that can be specifically got by comparing and received signal quality and corresponding threshold
The magnitude relationship of value, wherein, when the communication terminal is currently under GSM network standard, received signal strength and reception are believed
The two signal parameters of number quality are respectively received signal strength indicator and signal to noise ratio.It should be noted that the reception signal
Intensity instruction resulting first comparative result with the received signal strength threshold value compared with, and the signal to noise ratio with it is described
Received signal quality threshold value is compared resulting second comparative result.Next the mode of assessment is illustrated, specific point
For following several situations：
It is that the received signal strength indicator is less than the received signal strength threshold value in first comparative result, or
It is that the signal to noise ratio is less than the received signal quality threshold value, i.e. received signal strength indicator and letter in second comparative result
Make an uproar and be less than than both one of them when each correspond to the threshold value set, be considered as assessment result be current primary antenna performance compared with
Difference, antenna switching flow can be triggered.
Compared by the performance parameter of the primary antenna signal of acquisition and the threshold value of setting, trigger antenna switching flow, a side
Face, only when meeting trigger condition, illustrate that current primary antenna performance is in poor state, the now switching of triggering following again
Journey, so as to improve the accuracy of follow-up switching judging and reliability；On the other hand, when being unsatisfactory for corresponding trigger condition,
Illustrate that current primary antenna performance is in more excellent state, may not necessarily now perform follow-up antenna handoff procedure, therefore can keep away
Exempt from frequently to carry out antenna switching, reduce the occupancy to communication terminal system resource, reduce the power consumption of communication terminal.
In some instances, can also be that signal intensity instruction is strong less than the signal in first comparative result
Threshold value is spent, and is that the signal to noise ratio is less than the signal quality threshold, i.e. received signal strength in second comparative result
When both instruction and signal to noise ratio are required for being less than set respective threshold, it can just think that assessment result is poor for signal performance,
Antenna switching flow is now triggered again.
We can first carry out judging the magnitude relationship of signal to noise ratio and the received signal quality threshold value, if signal to noise ratio is less than
The received signal quality threshold value, then the received signal strength indicator and the received signal strength threshold value are subjected to size ratio
Compared with if current received signal strength instruction is again smaller than the received signal strength threshold value, then it is signal to be considered as assessment result
Poor-performing, antenna switching flow can be triggered；Similarly, the order being compared can be adjusted by we, first by described in
Received signal strength indicator and the received signal strength threshold value carry out size comparison, if current received signal strength instruction is less than
The received signal strength threshold value, then judge the magnitude relationship of signal to noise ratio and the received signal quality threshold value, if noise
Than again smaller than the received signal quality threshold value, then be considered as the poor-performing that assessment result is signal, antenna can be triggered
Switching flow.The sequencing of above-mentioned deterministic process can adjust, but once it is determined that sequencing, then the judgement first carried out
The prerequisite for the judgement flow that flow is carried out after just becoming, if the judged result first carried out can not meet to carry out latter judgement
Condition requirement, then will not carry out latter judgement, this saves flow is judged, saving that also can be to a certain extent communication end
The power consumption at end.When being unsatisfactory for trigger condition, illustrate that the performance of current primary antenna is more excellent, current antenna combination can be continued to use.
In addition to the mode of current performance parameters and performance parameter threshold value is compared in above-mentioned direct judgement, we additionally provide
A kind of normalization numerical value for being normalized to obtain by performance parameter value is compared with the normalized threshold pre-set
Mode, it is described normalization numerical value with the normalized threshold compared with obtained by the 3rd comparative result, according to the 3rd compare
Relatively result come judge to determine whether trigger antenna switching flow, the mode of this normalized comparison is illustrated below：
When communication terminal is under GSM network standard, by received signal strength be specially received signal strength indicator and
Signal to noise ratio is normalized.Specifically, for example, the received signal strength indicator currently obtained from primary antenna and noise score
Not Wei P and Q, the affiliated UHF band reception signal intensity instruction of setting and the maximum of signal to noise ratio are respectively PMAXAnd QMAX, by the P
Divided by the PMAXTo be normalized to obtain P/PMAX, similarly by the Q divided by QMAXTo be normalized to obtain Q/QMAX, then will
The two parameter P/P obtained after above-mentioned normalizedMAXAnd Q/QMAXCarry out asking processing to obtain a result parameter (assuming that being equal to
M), so as to obtain the first normalization numerical value M, finally obtained value M and our normalized thresholds (assuming that being equal to N) of setting are entered
Row compares.
After received signal strength indicator and signal to noise ratio are normalized respectively, summation operation is carried out, obtains the
One normalization numerical value, then obtained summed result and the normalization pre-set and threshold value are compared, obtain the 3rd and compare
As a result, the 3rd comparative result is whether the first normalization numerical value is less than the normalization and threshold value, then judge whether can be with
Trigger antenna switching flow.
For example, the received signal strength indicator and signal to noise ratio that are currently obtained from primary antenna are respectively P1And Q1, setting it is affiliated
UHF band reception signal intensity indicates and the maximum of signal to noise ratio is respectively PMAXAnd QMAX, by the P1Divided by the PMAXTo carry out
Normalization obtains P1/PMAX, similarly by Q1Divided by the QMAXTo be normalized to obtain Q1/QMAX, then by above-mentioned normalized
The two parameter P obtained afterwards1/PMAXAnd Q1/QMAXCarry out summation process P1/PMAX+Q1/QMAX(assuming that being equal to M1), so as to obtain
One normalization numerical value M1, the value M that will finally obtain1The normalization set with us and threshold value are (assuming that be equal to N1) be compared, if
M1<N1When, i.e. it is that the described first normalization numerical value is less than the normalization and threshold value to meet the 3rd comparative result, then can trigger
Antenna switching flow；If M1≥N1, then antenna switching flow will not be triggered.
In some instances, the received signal strength indicator currently obtained and signal to noise ratio can also be normalized
Afterwards, the two values after normalized are carried out asking business's computing, obtains the second normalization numerical value, then ask business to tie by what is obtained
Fruit and the normalization business's threshold value pre-set are compared, and obtain the 3rd comparative result, and the 3rd comparative result is the second normalization
Numerical value is more than or equal to the normalization and threshold value, it is determined that can trigger antenna switching flow.For example, currently obtained from primary antenna
Received signal strength indicator and signal to noise ratio be respectively P2And Q2, the affiliated UHF band reception signal intensity of setting indicates and signal to noise ratio
Maximum be respectively PMAXAnd QMAX, while will be by the P2Divided by the PMAXTo be normalized to obtain P2/PMAX, similarly will
Q2Divided by the QMAXTo be normalized to obtain Q2/QMAX, then the two parameter P that will be obtained after above-mentioned normalized2/PMAXWith
Q2/QMAXCarry out asking business to handle (P2/PMAX)/(Q2/QMAX) (assuming that being equal to M2), so as to obtain the second normalization numerical value M2, finally will
Obtained value M2The normalization business threshold value set with us is (assuming that be equal to N2), it is compared, if M2≥N2When, i.e. meet the 3rd
Comparative result is that the described second normalization numerical value is more than or equal to normalization business's threshold value, then can trigger antenna switching flow；
If M2<N2, then antenna switching flow will not be triggered.
In some instances, the received signal strength indicator currently obtained and signal to noise ratio can also be normalized
Afterwards, the two values after normalized are carried out seeking difference operation, obtains the 3rd normalization numerical value, then poor knot is sought by what is obtained
Fruit and the normalization difference threshold value pre-set are compared, and obtain the 3rd comparative result, and the 3rd comparative result is returned for the described 3rd
One, which changes numerical value, is more than or equal to the poor threshold value of normalization, then judges that antenna switching flow can be triggered.For example, currently from primary antenna
The received signal strength indicator and signal to noise ratio of acquisition are respectively P3And Q3, the affiliated UHF band reception signal intensity of setting indicates and letter
Make an uproar than maximum be respectively PMAXAnd QMAX, while will be by the P3Divided by the PMAXTo be normalized to obtain P3/PMAX, together
Manage Q3Divided by the QMAXTo be normalized to obtain Q3/QMAX, then the two parameter P that will be obtained after above-mentioned normalized3/
PMAXAnd Q3/QMAXCarry out seeking difference processing (P3/PMAX)-(Q3/QMAX) (assuming that being equal to M3), so as to obtain the 3rd normalization numerical value M3,
The value M that will finally obtain3The normalization difference threshold value set with us is (assuming that be equal to N3), it is compared, if M3≥N3When, i.e. it is full
The 3rd comparative result of foot is that the described 3rd normalization numerical value is more than or equal to the poor threshold value of normalization, then can trigger antenna switching
Flow；If M3<N3, then antenna switching flow will not be triggered.
It should be noted that should not be limited to it is above-mentioned by the signal intensity instruction and signal to noise ratio be normalized
Three kind modes of the obtained normalization numerical value compared with the normalized threshold pre-set, normalized and and normalization
Threshold value compares judges whether that triggering antenna cuts it is possible to prevente effectively from two parameters occur and being in influence communication terminal under extremity
The situation of change of current journey, it can make it that the judgement of communication terminal is more accurate and effective.
