Abstract
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.

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;
- and
- 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.
An apparatus for setting a working mode of power amplifier (PA) blanking, comprising:
- a detecting unit configured to, when a Global Positioning System (GPS) is running, detect, at a preset interval, whether a Global System for Mobile Communications (GSM) service is running;
- an acquiring unit configured to, when the detecting unit detects that the GSM service is running, acquire a current quantity of timeslots occupied by the GSM service and a current power control level used by the GSM service;
- a searching unit configured to search, according to the current quantity of timeslots and the current power control level that are acquired by the acquiring unit, 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;
- a determining unit configured to determine whether the indication information found by the searching unit is consistent with a current working mode of the PA blanking;
- and
- a processing unit configured to set, when the determining unit determines that 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.
