Embodiment one
Reference picture 1, show a kind of step flow chart of antenna tuning method of the embodiment of the present invention one.
The antenna tuning method of the embodiment of the present invention comprises the following steps：
Step 101：After mobile terminal is opened, the main carrier bandwidth of antenna is defined as working frequency range.
After presetting mobile terminal unlatching in mobile terminal, default main carrier antenna condition is called to stay net.Wherein, master is called
It is bandwidth corresponding to main carrier by the working frequency range of antenna that carrier antenna state, which stays net,.
Main carrier bandwidth, which why is set, as working frequency range is due to, uplink and downlink are contained simultaneously in main carrier
Channel, and only descending channel is included in secondary carrier, only only main carrier when, basic proper communication can be maintained, and only
Only secondary carrier when be unable to maintain that basic proper communication.
Step 102：Judge whether descending interband carrier aggregation pattern opens.
Mainly whether there is descending interband secondary carrier signal in the network information of mobile terminal persistent district by detecting when judging
To realize.If descending interband carrier aggregation pattern is opened, step 103 is performed, if descending interband carrier aggregation pattern is not opened,
Then maintain main carrier antenna condition.
Step 103：When descending interband carrier aggregation pattern is opened, the main carrier downlink bandwidth of antenna and auxiliary load are obtained
Wavestrip is wide.
Main carrier downlink bandwidth, secondary carrier bandwidth are carried to send in downlink data to mobile terminal, mobile terminal and received
To after downlink data, you can determine the downlink bandwidth of the two subcarriers.Because secondary carrier only includes down channel, therefore auxiliary load
The downlink bandwidth of the wide as secondary carrier of wavestrip.
Step 104：Judge whether main carrier downlink bandwidth is less than secondary carrier bandwidth；If so, then perform step 105；If it is not,
Then perform step 106.
Such as：Main carrier is B1, subcarrier B3, the downlink bandwidth allocated B1 when carrying out descending interband carrier aggregation
For 5MHZ, a width of 20MHZ of band allocated B3, B1 and B3 downlink bandwidth is subjected to size and compared, then can determine that B3 bandwidth
Downlink bandwidth more than B1.

Humorous method, when mobile terminal is operated in descending interband carrier aggregation state, the working frequency range of antenna be tuned to downlink bandwidth it is big
Subcarrier corresponding under frequency range, and the antenna performance of the big subcarrier of downlink bandwidth compares the less subcarrier day of downlink bandwidth
Linearly can be more excellent, therefore the downloading experience of user can be lifted.
Embodiment two
Reference picture 2, show a kind of step flow chart of antenna tuning method of the embodiment of the present invention two.
The antenna tuning method of the embodiment of the present invention specifically includes following steps：
Step 201：After mobile terminal is opened, the main carrier bandwidth of antenna is defined as working frequency range.
After a kind of preferable mobile terminal is opened, determine that the mode of the working frequency range of antenna is as follows：
First, after mobile terminal is opened, default antenna condition is determined；
Wherein default antenna condition is first state corresponding to main carrier.Antenna condition includes first state and second
State, each state correspond to different subcarriers, and main carrier is corresponded to first state in the embodiment of the present invention, and the second state is corresponding
Illustrated exemplified by subcarrier.
Secondly, the main carrier bandwidth of antenna is determined；
The main carrier bandwidth of different antennae is different, it is therefore desirable in mobile terminal is determined after mobile terminal starts first when
The main carrier bandwidth of preceding installed antenna.
Finally, main carrier bandwidth is defined as working frequency range.
In the embodiment of the present invention, it is due to be wrapped simultaneously in main carrier why to set main carrier bandwidth as working frequency range
Contained the channel of uplink and downlink, and only descending channel included in secondary carrier, only only main carrier when, can maintain basic
Proper communication, and only only have during secondary carrier and be unable to maintain that basic proper communication.
Step 202：Judge whether there is descending interband secondary carrier signal in the network information of mobile terminal persistent district；If it is not,
Then perform step 203；If so, then perform step 204.
Mobile terminal is after net to certain special frequency channel, you can passes through the frequency range and sends upstream data, receives persistent district hair
The downlink data sent the i.e. network information.If there is descending interband carrier signal in downlink data, illustrate that descending carrier removes main carrier
Secondary carrier also be present outside, descending interband carrier aggregation pattern has turned on.
Step 203：Determine that descending interband carrier aggregation pattern is not opened.
When determining that descending interband carrier aggregation pattern is not opened, then current main carrier antenna condition is maintained.
Step 204：Determine that descending interband carrier aggregation pattern has turned on.
In the embodiment of the present invention, after powering, antenna tuning unit calls default antenna condition to mobile terminal, makes movement
Terminal stays net to special frequency channel.Then according to the information in net of mobile terminal, whether default descending interband carrier aggregation is detected
Start, if terminal already is resident within the network of descending interband carrier aggregation, give tacit consent to calling antenna condition it is default based on carry
The antenna condition of frequency range where ripple.Why so do, be because for descending interband carrier aggregation, included simultaneously in main carrier
The channel of uplink and downlink, and only include descending channel in secondary carrier, thus only only main carrier when, can maintain basic
Proper communication, and subcarrier mainly to further lifting downstream rate.
Step 205：Obtain the main carrier downlink bandwidth and secondary carrier bandwidth of antenna.
When mobile terminal is resident descending interband carrier aggregation state, then the information that can be reported by mobile terminal network side
The main carrier downlink bandwidth and secondary carrier bandwidth of reading antenna.
For main carrier downlink bandwidth, the specific method of salary distribution of secondary carrier bandwidth, determined by the network of operator institute cloth.
Step 206：Judge whether main carrier downlink bandwidth is less than secondary carrier bandwidth；If it is not, then perform step 207；If so,
Then perform step 208.
Preferably, after the main carrier downlink bandwidth of antenna and secondary carrier bandwidth is obtained, delay preset time performs
Step 206 carries out antenna condition switching.This kind of preferable mode makes the net of staying of mobile terminal more stablize.
Step 207:Keep the working frequency range of a width of antenna of main carrier band.
Step 208：By the working frequency range that secondary carrier Bandwidth adjustment is antenna
When the descending allocated bandwidth of main carrier is less than the bandwidth that secondary carrier is allocated, antenna is switched to where secondary carrier
Antenna condition corresponding to frequency range, to lift network downstream speed.
Step 209：Judge whether secondary carrier signal intensity increment is more than the first preset value, obtain the first judged result.
Wherein, the first preset value can be configured according to the actual requirements by those skilled in the art, the embodiment of the present invention
In this is not specifically limited.
Due to secondary carrier be mainly used in lifted downstream rate, therefore by antenna condition by main carrier antenna condition switching supplemented by
After carrier antenna state, downstream signal intensity will have been lifted, therefore secondary carrier signal intensity increment is judged.
Step 210：Judge whether main carrier ascending power reduction is default less than second and be worth to the second judged result, with
And whether main carrier downstream signal intensity reduction amount is preset less than the 3rd and is worth to the 3rd judged result.
Wherein, the second preset value, the 3rd preset value can be configured according to the actual requirements by those skilled in the art, this
This is not specifically limited in inventive embodiments.
After antenna condition is switched into secondary carrier antenna condition by main carrier antenna condition, the ascending power of main carrier, under
Row signal intensity can be affected, it is therefore desirable to judge whether influence of this antenna condition switching to these two aspects reaches
Limit.
Step 211：According to the first judged result, the second judged result and the 3rd judged result, it is determined whether keep auxiliary
Carrier bandwidths are the working frequency range of antenna.
A kind of the first judged result of preferably foundation, the second judged result and the 3rd judged result, it is determined whether keep
The mode of the working frequency range of a width of antenna of secondary carrier band is as follows：
If the first judged result, the second judged result and the 3rd judged result are when being, secondary carrier bandwidth is kept
For the working frequency range of antenna；
If in the first judged result, the second judged result and the 3rd judged result it is at least one for it is no when, by main load
The wide working frequency range for being adjusted to antenna of wavestrip.
After determining to keep the working frequency range of a width of antenna of secondary carrier band in step 211, then return and perform step 209, follow
Ring performs step 209 to step 211；When in step 211 determine by main carrier Bandwidth adjustment be antenna working frequency range after, then return
Receipt row step 205 obtains the main carrier downlink bandwidth and secondary carrier bandwidth of antenna, and judges the size of the two, if secondary carrier
Band is wider than main carrier downlink bandwidth, then by secondary carrier Bandwidth adjustment be the antenna working frequency range, it is on the contrary then without day
Line working frequency range adjusts.To antenna work during circulation execution step 205 to step 211 then achievable descending interband carrier set
Make the dynamic adjustment of frequency range.Enter Mobile state adjustment to Antenna Operation frequency range, the return loss of antenna can be reduced, so as to lift day
The downlink data treatment effeciency of line.
The antenna tuning method in the embodiment of the present invention is illustrated with an instantiation below.
Such as：The antenna installed in mobile terminal can realize the descending interband carrier aggregation of two subcarriers of B1+B3,
Wherein, B1 is main carrier, and B3 is secondary carrier, and B1 is corresponding corresponding with a width of 20MHZ with a width of 5MHZ, B3.
After mobile terminal unlatching, the working frequency range of antenna is adjusted into 5MHZ makes mobile terminal under net to the frequency range.
Then whether opened according to the descending interband carrier aggregation pattern of the infomation detection in net of mobile terminal, the descending bands of B1 are determined if opening
It is wider than B3 bandwidth, then 20MHZ is adjusted to new Antenna Operation frequency range, the letter that secondary carrier B3 is received is judged after the completion of adjustment
Whether number intensity increment is more than the first preset value, judges whether main carrier B1 ascending powers reduction is less than second and default is worth to
Whether the second judged result, and main carrier B1 downstream signal intensity reductions amount are less than the 3rd preset value；If three judged results
It is to be, then maintains current secondary carrier antenna condition i.e. using bandwidth corresponding to secondary carrier B3 as the working frequency range of antenna；If three
It is no to have a result in individual judged result, then recovers main carrier antenna condition i.e. using bandwidth corresponding to main carrier B1 as antenna
Working condition.
