Referring to fig. 3, an antenna tuning method provided in an embodiment of the present invention is applied to the mobile terminal, and the method includes:
step S210: the mobile terminal acquires a wireless communication frequency band when meeting a first preset condition.
Generally, a mobile terminal performs wireless communication based on a certain wireless communication frequency band. Correspondingly, the mobile terminal is also based on a certain wireless communication frequency band when establishing the wireless link. In this embodiment, the mobile terminal acquires the wireless communication band based on which the wireless link is subsequently established when the first preset condition is satisfied.
By way of example, the first preset condition includes at least one of the following conditions: when the mobile terminal establishes a communication link with a base station; after the mobile terminal establishes a communication link with a base station; after the mobile terminal moves according to a preset track; and when the distance signal collected by the distance sensor arranged on one side of the screen of the mobile terminal changes.
When the mobile terminal establishes the communication link with the base station, the mobile terminal is characterized to respond to the dialing operation of a user or other trigger events, and a request for establishing the communication link is sent to the base station. After the communication link is established between the mobile terminal and the base station, the characteristic that the mobile terminal still monitors a plurality of feed points of an antenna of the mobile terminal in real time or in a preset period after the wireless communication link with the base station is established is that the signal intensity of the feed point is the best corresponding to the wireless communication frequency band of the established communication link.
For example, six feedpoints S1, S2, S3, S4, S5, and S6 are disposed in the mobile terminal antenna, and correspond to different antenna turn-on lengths, respectively, and the optimal wireless communication frequency bands corresponding to different feedpoints at a certain time are different, as shown in fig. 4, an abscissa in fig. 4 represents a wireless communication frequency band, and it can be seen that at this time, the wireless communication frequency band corresponding to the feedpoint S1 is 971MHZ, the wireless communication frequency band corresponding to the feedpoint S2 is 1830MHZ, the wireless communication frequency band corresponding to the feedpoint S3 is 2074MHZ, the wireless communication frequency band corresponding to the feedpoint S4 is 2263MHZ, and the wireless communication frequency band corresponding to the feedpoint S5 is 2464 MHZ. The mobile terminal will still listen to the best one of the 890MhZ radio signals on the six feedpoints S1, S2, S3, S4, S5 and S6. For example, as shown in fig. 5, the switch of the mobile terminal is currently the 1900MHZ wireless communication performed by the turned-on feed point S2, and when the optimum 1900MHZ wireless signal at the S3 feed point is detected, as shown in fig. 6, the mobile terminal controls the switch to gate the S3 feed point, so as to establish the 1900 MHZ-based wireless communication link with the base station based on the S3 feed point. It should be noted that the optimal wireless communication frequency band of a certain feed point is a frequency band with the strongest signal strength or a signal strength value exceeding a preset value. The signal strength may be an RSSI value or other parameter values that may represent the strength of the wireless signal.
And after the mobile terminal moves according to the preset track, representing that the mobile terminal is in a state of monitoring that the motion track of the mobile terminal accords with the preset path. For example, when a user leans against the mobile terminal to answer a call, the mobile terminal is in a relatively vertical state, and when the user places the mobile terminal on a desktop, the mobile terminal is in a relatively horizontal state, and when the movement track of the mobile terminal from the relatively vertical state to the relatively horizontal state is monitored to be a preset track, the mobile terminal acquires a wireless communication frequency band.
It can be understood that the wireless communication band acquired by the mobile terminal is a wireless communication band supported by the mobile terminal itself, for example, the mobile terminal supports the 890-909MHZ band and the 1880 MHZ-1920 MHZ band, and then the mobile terminal can acquire the wireless communication band in the 890-909MHZ band and the 1880 MHZ-1920 MHZ band.
It should be noted that the number of feeders and the wireless communication frequency band of the injury are merely exemplary, and the specific number of feeders and the wireless communication frequency band may be set according to different application environments.
Step S220: and acquiring a target feed point from the plurality of feed points, wherein the target feed point is a feed point of which the wireless signal intensity corresponding to the wireless communication frequency band meets a second preset condition.
After the frequency band to be wirelessly communicated is obtained, the target feed point is selected. The target feed point is a feed point, of the plurality of feed points, of which the wireless signal intensity corresponding to the wireless communication frequency band meets a second preset condition. The second preset condition is that the wireless signal intensity is maximum or the wireless signal intensity is greater than a preset value.
The target feedpoint obtained based on the obtained wireless communication frequency band may be determined by re-acquiring signal intensities of a plurality of feedpoints corresponding to the obtained wireless communication frequency band after the wireless communication frequency band is obtained. In order to improve the acquisition efficiency and reduce the waiting time of the user, the waiting time may be determined based on the signal strength of the wireless communication frequency band that has been acquired by the mobile terminal and corresponds to a plurality of feeders that have been stored in advance before the mobile terminal acquires the wireless communication frequency band.
As a mode, the wireless signal strength of the plurality of feed points corresponding to the wireless communication frequency band is obtained in advance through an MIPI interface included in the mobile terminal.
Step S230: and controlling the switch to gate the target feed point so that the mobile terminal can carry out wireless communication based on the wireless communication frequency band.
In the antenna tuning method provided by the embodiment of the present invention, a plurality of feed points are set in an antenna and a switch for selecting and gating the feed points is set, so that the mobile terminal obtains a wireless communication frequency band when meeting a first preset condition, then obtains a target feed point, of which the wireless signal strength corresponding to the wireless communication frequency band meets a second preset condition, from the feed points, and controls the switch to gate the target feed point, so that the mobile terminal performs wireless communication based on the wireless communication frequency band. Thereby enabling wireless communication based on a plurality of wireless communication bands even if only one antenna is provided in the mobile terminal. In addition, because an antenna is not required to be independently arranged for each wireless communication frequency band, the space of the mobile terminal is saved.
Referring to fig. 7, an antenna tuning method provided in an embodiment of the present invention is applied to the mobile terminal, and the method includes:
step S310: and the mobile terminal detects the wireless signal intensity of the plurality of feed points corresponding to the plurality of wireless communication frequency bands respectively at a preset frequency.
As a mode, the wireless signal strength of the plurality of feed points corresponding to the wireless communication frequency band is obtained in advance through an MIPI interface included in the mobile terminal.
Step S320: and storing a target feed point corresponding to each wireless signal frequency band, wherein the target feed point is a feed point of which the wireless signal intensity corresponding to each wireless signal frequency band meets a second preset condition, so that when the mobile terminal performs communication in the selected wireless signal frequency band, the switch is controlled to be switched on to perform wireless communication based on the selected wireless communication frequency band.
In summary, in the antenna tuning method and the mobile terminal provided in the embodiments of the present invention, a plurality of feed points are set in an antenna, and a switch for selecting and gating the feed points is set, so that the mobile terminal obtains a wireless communication frequency band when meeting a first preset condition, then obtains a target feed point, in the plurality of feed points, where the wireless signal strength corresponding to the wireless communication frequency band meets a second preset condition, and then controls the switch to gate the target feed point, so that the mobile terminal performs wireless communication based on the wireless communication frequency band. Thereby enabling wireless communication based on a plurality of wireless communication bands even if only one antenna is provided in the mobile terminal. In addition, because an antenna is not required to be independently arranged for each wireless communication frequency band, the space of the mobile terminal is saved.
