Problems solved by technology

Since it is difficult for the Wi-Fi filter and the TDD-LTE filter on the terminal to completely eliminate the interference from adjacent frequency bands, when Wi-Fi and TDD-LTE are working at the same time, it is easy to generate adjacency between the two. frequency interference

Abstract

The embodiment of the invention discloses a method and a device for switching an access point and a mobile terminal. The method comprises the following steps: acquiring a standby access point when the terminal is determined to be in a preset adjacent-channel interference state, wherein the standby access point is an accessible access point other than a current access point; detecting whether the standby access point satisfies a preset low adjacent-channel interference condition or not; if the standby access point is detected to satisfy the preset low adjacent-channel interference condition, determining the standby access point as a target access point; and controlling the terminal to switch to the target access point. Compared with the prior art, the method, the device and the mobile terminal have the advantages that the terminal can be switched to the standby access point satisfying the preset low adjacent-channel interference condition when the terminal is in the preset adjacent-channel interference state, so that adjacent-channel interference inside the terminal is lowered.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method, a device and a mobile terminal for switching an access point. Background technique [0002] Wireless Fidelity (Wireless Fidelity, hereinafter referred to as Wi-Fi) is a technology that allows electronic devices to connect to a wireless local area network, usually using a 2.4GHz or 5GHz radio frequency band. Among them, the frequency range of the 2.4GHz frequency band used by Wi-Fi is 2400-2483.5MHz, and its bandwidth is 83.5MHz, and 14 sub-channels are divided into this bandwidth. The frequency bands used by the Time Division Duplexing Long Term Evolution (TDD-LTE) communication technology include frequency bands numbered 38, 39, 40 and 41, namely Band 38, Band 39, Band 40 and Band 41. . Among them, Band 40 covers a range of 2300-2400MHz, and Band 41 covers a range of 2496-2690MHz. [0003] It can be known from the above that the lower frequency par...
