Below interference threshold.
The power limit instruction sent by receiving processor, the transmission power that can systematically adjust first antenna are big
It is small, prevent the limitation to maximum antenna transmission power to be not up to standard.
Step 402, modem judges whether the transmitting antenna of radio-frequency module work at present is first antenna.
Wherein, above-mentioned first antenna is located at close-shot as head end, and modem can pass through the state of acquisition radio-frequency module
Whether information is first antenna come the transmitting antenna for judging work at present.
It, can be to avoid waste work by judging whether the transmitting antenna of the radio-frequency module work at present is first antenna
Efficiency, because transmission power when dolly-out,ing dolly-back as head end Antenna Operation there is no fear of generating interference, work at present to camera
Transmitting antenna be first antenna when just execution step 403.
Step 403, modem limit the transmission power of the first antenna antenna transmission power interference threshold with
Under.
Wherein, modem is according to the power limit instruction received to the transmission power of the first antenna of radio-frequency module
It is limited, if the transmission power at this time of first antenna is more than antenna transmission power interference threshold, modem is by the
The transmission power of one antenna return back to above-mentioned antenna transmission power interference threshold hereinafter, if the transmission power at this time of first antenna
It is less than antenna transmission power interference threshold, then limiting its transmission power and will not fluctuate to above-mentioned day due to modem
It is more than line transmission power interference threshold.
By limit the radio-frequency module first antenna transmission power the antenna transmission power interference threshold with
Under, the transmission power for being located at the transmitting antenna of nearly camera side in radio-frequency module can be carried out certain when camera works
The adjustment of degree, the interference for generating it to camera are substantially reduced, and reduction brings the appreciable camera flower screen of user or card
The bad experience paused.

Step 506.
Step 506, modem sends feedback information to application processor, and the feedback information is for making using processing
Device re-execute the steps 501.
Step 507, modem judges whether the radio-frequency module meets antenna switching condition.
Wherein it is possible to the signal condition by judging current second antenna, when the signal condition of the second antenna is in normal
When state, then assert and meet antenna switching condition, when the signal condition of the second antenna is not enough to that it is supported to complete normal work
When, for example it will will lead to no network using the second antenna at this time, then being just unsatisfactory for antenna switching condition at this time.
If meeting antenna switching condition, 508 are thened follow the steps, if being unsatisfactory for antenna switching condition, thens follow the steps 509.
By judging whether the radio-frequency module meets antenna switching condition, can be prevented from another angle camera by
To the interference of antenna transmission power, the efficiency of the practice of the application can be improved.
Step 508, modem switches the transmitting antenna of the radio-frequency module work at present from the first antenna
To the second antenna.
Wherein, the second antenna, which is located at, dolly-out,s dolly-back as head end, and modem can directly control first antenna, and temporarily entrance is stopped
Dormancy state, the second antenna of control take over first antenna and continue normal power emission.
It, can be with by the way that the transmitting antenna of the radio-frequency module work at present is switched to the second antenna from the first antenna
The interference for generating it to camera is substantially reduced, and reduces the bad body for bringing the appreciable camera flower screen of user or Caton
It tests.
Step 509, modem limits the transmission power of the first antenna in the antenna transmission power interference threshold
