Method and apparatus for setting working mode of PA blanking
View Patent ↗A method and an apparatus for setting a working mode of power amplifier (PA) blanking are disclosed, which resolve a problem that, in the prior art, when a Global System for Mobile Communications (GSM) is working, because a PA blanking function cannot be configured flexibly to an enabled state or a disabled state, quality of a Global Positioning System (GPS) receiving signal is degraded. When a GPS is running, it is detected, at a preset interval, whether a GSM service is running. When the GSM service is running, a current quantity of timeslots occupied by the GSM service and a current power control level used by the GSM service are acquired.
1. A method for setting a working mode of power amplifier (PA) blanking, comprising:
detecting, at a preset interval, when a Global Positioning System (GPS) is running, whether a Global System for Mobile Communications (GSM) service is running;
acquiring a current quantity of timeslots occupied by the GSM service and a current power control level used by the GSM service, when the GSM service is running;
searching, according to the current quantity of timeslots and the current power control level, a preset table for indication information of the working mode of PA blanking corresponding to the current quantity of timeslots and the current power control level, wherein the preset table comprises indication information of working modes of the PA blanking that correspond to different quantities of timeslots occupied by the GSM service and different power control levels used by the GSM service, and wherein the indication information is used to indicate that the working mode of the PA blanking is in an enabled state or a disabled state;
determining whether the indication information is consistent with a current working mode of the PA blanking;
setting, when the indication information is not consistent with the current working mode of the PA blanking, the current working mode of the PA blanking to a working mode corresponding to the indication information;
enabling the PA blanking when the working mode of the PA blanking is in the enabled state and the current working mode of the PA blanking is in the disabled state; and
disabling the PA blanking when the working mode of the PA blanking is in the disabled state and the current working mode of the PA blanking is in the enabled state.
2. The method for setting the working mode of PA blanking according to claim 1 , wherein detecting, at the preset interval, whether the GSM service is running comprises detecting, at the preset interval, whether a state value of the GSM service is a working state value.
3. The method for setting the working mode of PA blanking according to claim 1 , further comprising:
detecting the current working mode of the PA blanking, when the GSM service is not running; and
disabling the PA blanking, when the current working mode of the PA blanking is in the enabled state.
4. The method for setting the working mode of PA blanking according to claim 3 , further comprising maintaining the current working mode of the PA blanking on the current working mode of the PA blanking, when the indication information is consistent with the current working mode of the PA blanking.
5. An apparatus for setting a working mode of power amplifier (PA) blanking, comprising:
a memory; and
a processor coupled to the memory and configured to:
detect, at a preset interval, whether a Global System for Mobile Communications (GSM) service is running when a Global Positioning System (GPS) is running;
acquire a current quantity of timeslots occupied by the GSM service and a current power control level used by the GSM service when the GSM service is running;
search, according to the current quantity of timeslots and the current power control level, a preset table for indication information of a working mode of PA blanking corresponding to the current quantity of timeslots and the current power control level, wherein the preset table comprises indication information of working modes of the PA blanking that correspond to different quantities of timeslots occupied by the GSM service and different power control levels used by the GSM service, and wherein the indication information is used to indicate that the working mode of the PA blanking is in an enabled state or a disabled state;
determine whether the indication information is consistent with a current working mode of the PA blanking;
set the current working mode of the PA blanking to a working mode corresponding to the indication information when the indication information is not consistent with the current working mode of the PA blanking;
enable the PA blanking when the working mode of the PA blanking is in the enabled state and the current working mode of the PA blanking is in the disabled state; and
disable the PA blanking when the working mode of the PA blanking is in the disabled state and the current working mode of the PA blanking is in the enabled state.
6. The apparatus for setting the working mode of PA blanking according to claim 5 , wherein the processor is configured to detect, at the preset interval, whether a state value of the GSM service is a working state value.
7. The apparatus for setting the working mode of PA blanking according to claim 5 , wherein the processor is further configured to:
detect the current working mode of the PA blanking when the GSM service is not running; and
disable the PA blanking when the processor detects that the current working mode of the PA blanking is in the enabled state.
8. The apparatus for setting the working mode of PA blanking according to claim 7 , wherein the processor is further configured to perform no processing on the current working mode of the PA blanking when the processor determines that the indication information is consistent with the current working mode of the PA blanking.
