Embodiment 1

[0021] figure 1 It is a schematic flowchart of a method for reducing GPS interference of the Global Positioning System provided by Embodiment 1 of the present invention. The method can be executed by a device for reducing GPS interference of the Global Positioning System, wherein the device can be implemented by software and / or hardware, and generally integrated in the mobile terminal.

[0022] Such as figure 1 As shown, a method for reducing GPS interference of the global positioning system provided by Embodiment 1 of the present invention specifically includes the following operations:

[0023] Step S101, after detecting that the GPS is turned on, start the multi-core working mode by applying for a set number of CPU cores to work, so that the operating frequency of the electronic device is higher than the operating frequency of the GPS receiver, wherein the set number is an integer greater than 1.

[0024] In this embodiment, when the user needs to use the GPS function, f...

Embodiment 2

[0041] figure 2 It is a schematic flow diagram of a method for reducing GPS interference of the global positioning system provided by Embodiment 2 of the present invention. This Embodiment 2 is optimized on the basis of the above-mentioned embodiments. In this embodiment, the step "working on the GPS In the process, if the set cancellation condition is satisfied, then cancel the CPU multi-core work mode" is further optimized as: monitor the GPS work process; judge whether the GPS work process is running in the background; if so, directly cancel the CPU multi-core work mode; if not, Then, after the GPS captures the satellite signal, the CPU multi-core working mode is cancelled.

[0042] Such as figure 2 As shown, a method for reducing GPS interference of the global positioning system provided by Embodiment 2 of the present invention specifically includes the following operations:

[0043] Step S201, after detecting that the GPS is turned on, enable the multi-core working mo...

Embodiment 3

[0055] image 3 A schematic flow chart of a method for reducing GPS interference provided by Embodiment 3 of the present invention. Embodiment 3 is optimized on the basis of the above-mentioned embodiment. In this embodiment, the step "in the GPS working process Among them, if the setting cancellation condition is satisfied, then cancel the CPU multi-core working mode" is further optimized as: monitoring the screen status of the mobile terminal during the GPS working process; After the signal, cancel the CPU multi-core working mode; otherwise, if the mobile terminal screen is in a lock screen state or a standby state, then directly cancel the CPU multi-core working mode.

[0056] In this embodiment, it should be noted that the third embodiment can be understood as a technical solution in parallel with the second embodiment, that is, in the working state of GPS, in addition to the CPU multi-core working mode mentioned in the second embodiment In addition to the cancellation co...

Abstract

The embodiment of the invention discloses a method and apparatus for reducing GPS interference, and a mobile terminal. The method comprises: after turning on of a GPS is detected, a set number of CPUs are applied for core working to start a multi-core working mode and thus the working frequency of an electronic device is higher than that of a GPS receiver, wherein the set number is an integer larger than 1; and during the GPS working process, if a set cancelling condition is met, the multi-core working mode of the CPUs is cancelled. With the method, a problem of the noise interference on the GPS receiver by the electronic device can be solved and the precision of the mobile terminal GPS can be improved. Besides, reasonable utilization of the CPU resources of the mobile terminal during GPS working is also realized, thereby guaranteeing normal processing on other functional applications by the CPU in the mobile terminal.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of GPS, and in particular to a method, a device and a mobile terminal for reducing GPS interference of a global positioning system. Background technique [0002] Global Positioning System (Global Positioning System, GPS) is a system that uses GPS positioning satellites to perform real-time positioning and navigation around the world. At present, as a mature positioning and navigation system, GPS has been widely used. At the same time, GPS is gradually integrated into intelligent mobile terminals to provide convenience for people's life. [0003] In the smart mobile terminal, the integrated GPS receiver is mainly used to receive GPS satellite signals and determine the ground space position according to the received satellite signals. Therefore, when GPS receives satellite signals, it is susceptible to interference from various external signals. [0004] For example, during the GPS w...
