Abstract

The embodiment of the invention discloses an interference processing method, a device and mobile terminal, the problem thatwhen TDD frequency band and the GPS coexist, the TDD frequency band generatesinterference on the GPS to cause inaccurate GPS positioning or satellite loss is solved; The method comprises the steps of when it is monitored that the mobile terminal works in a first frequency band and a second frequency band at the same time, determining the first working state of the mobile terminal in the second frequency band according to the current position information of the mobile terminal and/or the carrier-to-noise ratio of the second frequency band; And determining whether to adjust the current working state of the mobile terminal in the second frequency band according to the first working state of the mobile terminal in the second frequency band. According to the technical scheme, the influence on the performance of the second frequency band when the first frequency band and the second frequency band coexist can be reduced to the maximum extent, and the problem that the user experience is influenced due to the fact that the mobile terminal directly stops working in thesecond frequency band is avoided.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to an interference processing method, device and mobile terminal. Background technique [0002] With the popularization of mobile terminals, there are many application scenarios for coexistence of multiple frequency bands, such as the coexistence of GPS (Global Positioning System, global positioning system) and TDD (Time Division Duplexing, time division duplexing) frequency bands. For example, there is a situation where GPS and LTE work together during location sharing and Voice LTE calls. The TX in the TDD frequency band will generate noise that falls into the GPS frequency band. At this time, if the suppression and antenna isolation on the TX channel reach If it is not required (the noise received at the GPS antenna must be less than -174dbm / Hz, otherwise the GPS performance will be degraded), the TX noise will be received by the GPS antenna, resulting in a decrease in ...
