Embodiment
Hereinafter, with reference to the accompanying drawings to embodiments of the invention are described in detail.However, it is possible to come in many different forms real
Apply the present invention, and the specific embodiment of the invention that should not be construed as limited to illustrate here.Conversely, there is provided these implementations
Example is in order to explain the principle and its practical application of the present invention, so that others skilled in the art are it will be appreciated that the present invention
Various embodiments and be suitable for the various modifications of specific intended application.In the accompanying drawings, identical label will be used for table all the time
Show identical element.
Reference picture 1, the method for the interference for the reduction mobile terminal gps signal that the present embodiment provides include step：
S1, judge whether mobile terminal is sending gps signal.
Wherein, mobile terminal needs to send location information to base station when placement of emergency calls, therefore, in step S1
In can by detect mobile terminal whether placement of emergency calls come judge mobile terminal whether send gps signal, certainly,
It can also judge whether mobile terminal is sending gps signal by other means.
If S2, mobile terminal send gps signal, whether the communications band of detection mobile terminal is B13 frequency ranges.
In step s 2, if mobile terminal does not send gps signal, the communications status maintains normal condition of mobile terminal,
Here, the normal condition of mobile terminal includes voice communication or data communicate.The different systems of mobile terminal include multiple respectively
Communications band, and can just produce interference when only the communications band of mobile terminal is B13 frequency ranges to gps signal, therefore, it is determined that
Whether the communications band that mobile terminal also needs to detect mobile terminal when sending gps signal is B13 frequency ranges.
If the communications band of S3, mobile terminal is B13 frequency ranges, the communications band of mobile terminal is adjusted.
In step s3, if the communications band of mobile terminal is not B13 frequency ranges, the communications status of mobile terminal maintains just
Normal state.
Three kinds of modes are provided in the present embodiment to be adjusted to the communications band of mobile terminal, pass through these three modes
Interference of the communications band to gps signal of mobile terminal can be reduced respectively, lift the positioning performance of mobile terminal.
Specifically, the communications band of mobile terminal is switched to change the communications band of mobile terminal for first way
Other communications bands are to switch to other frequency ranges after removing B13 frequency ranges, so, the signal of communication of gps signal and mobile terminal
It is transmitted respectively by different frequency ranges, gps signal will not be influenceed by the communications status of mobile terminal.
The second way is the antenna of switching mobile terminal, specifically, step is adjusted to the communications band of mobile terminal
Suddenly include：
Judge whether mobile terminal is communicated by upper antenna, wherein, mobile terminal includes upper antenna and lower antenna, on
Antenna and gps antenna are respectively positioned on the top of mobile terminal, and lower antenna is located at the bottom of mobile terminal, therefore, in mobile terminal
, it is necessary to judge whether mobile terminal is communicated by upper antenna when communications band is B13 frequency ranges；
If mobile terminal is communicated by upper antenna, the antenna of mobile terminal is switched into lower antenna, so will
Reduce interference of the signal of communication of mobile terminal to gps signal.If mobile terminal is communicated by lower antenna, mobile terminal
Communications status maintains normal condition.
The third mode is reduces the power of mobile terminal, specifically, reduces transmitting work(of the mobile terminal in B13 frequency ranges
Rate, for example, the transmission power of mobile terminal is reduced into 1~2dB.
Certainly, the second way and the third mode can be carried out simultaneously in the present embodiment, so, can be further
Reduce interference of the signal of communication of mobile terminal to gps signal.Specifically, step is adjusted to the communications band of mobile terminal
Including：
Judge whether mobile terminal is communicated by upper antenna；
If mobile terminal is communicated by upper antenna, the antenna of mobile terminal is switched into lower antenna, meanwhile, reduce
Transmission power of the mobile terminal in B13 frequency ranges；If mobile terminal is communicated by lower antenna, the communications status of mobile terminal
Maintains normal condition.
In the present embodiment, after the gps signal end of transmission, mobile terminal returns to original communications band or communication frequency
Rate or antenna are that mobile terminal returns to normal condition.
