Meet predetermined power backoff rules, if so, 350 are thened follow the steps, it is no to then follow the steps 380.
Wherein, predetermined power backoff rules include independent backoff rules and joint backoff rules.
Illustratively, if it is close to state that the usage scenario, which is the relative positional relationship, screen state is to extinguish shape
State and WiFi switch state are in an open state, it is determined that the usage scenario meets independent backoff rules.If described use field
Scape is that the relative positional relationship is close to state, and screen state is that illuminating state and WiFi switch state are in an open state,

2555MHz-2575MHz (China Unicom), 2370MHz-2390MHz and 2635MHz-2655MHz (China Telecom) etc..
Step 408 obtains antenna of the intelligent terminal in different communication frequency range according to the type and geographical location information
Power measurements.
Illustratively, SAR standard based on testing is determined according to geographical location, and the day of intelligent terminal is determined according to type
Line design information.The antenna power value that test is reduced every time can be determined according to Antenna Design information.According to intelligent terminal
Communications band, SAR standard and Antenna Design information, test the antenna power in different communication frequency range, and determination both met
SAR standard, and the target antenna power of intelligent terminal performance is not influenced.
The antenna fallback value that step 409, acquisition are arranged according to the antenna power test result, is protected using back-off table
