Embodiment Construction

[0032] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] The embodiment of the present invention provides a method to suspend USB3.0 data transmission when the mobile communication device performs wireless communication in certain scenarios, or use a low-speed USB mode (such as USB2.0) when the mobile communication device performs wireless communication, thereby It avoids USB3.0 (or USB3.1) and other possible relatively high-speed USB transmissions from interfering with the wireless communication of the mobile communication device.

[0034] figure 2 Shown is a flow chart of a mobile communication method for avoiding interference of a USB interface to a mobile communication device according to an embodiment of the present invention. Such as figure 2 As shown, the mobile commun...

Abstract

The invention discloses a mobile communication method and a mobile communication device. The mobile communication method is applied to the mobile communication device. The mobile communication method comprises the steps of detecting whether the mobile communication device is in a USB data transmission mode or not; judging whether the strength of the wireless communication signal of the mobile communication device in each wireless communication mode is smaller than a first threshold value or not; judging whether the strength of the wireless communication signal of the mobile communication device in any wireless communication mode is smaller than the first threshold value or not; on the condition that the mobile communication device is in the USB data transmission mode, switching the device from a first data transmission speed in the current USB transmission mode to a second data transmission speed in a low-speed USB transmission mode, wherein the first speed is larger than the second speed. As a result, the influence of the high-speed USB data transmission on the wireless communication of the mobile communication device can be avoided.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a mobile communication method and a mobile communication device. Background technique [0002] Due to the lower rate of USB2.0, the higher rate USB3.0 and USB3.1 will soon completely replace USB2.0. However, the spread spectrum processing of USB3.0 and USB3.1 causes its spectrum to cover from 0Hz to 5GHz, and the frequency of mobile phone communication is usually 700MHz to 2.7GHz, so USB2.0 data transmission is likely to cause interference to the wireless communication of mobile communication devices. [0003] Take USB3.0 as an example, figure 1 Shown is the measured signal spectrum of USB3.0. Depend on figure 1 It can be seen that the USB3.0 is likely to cause interference to the wireless communication of the mobile communication device. [0004] The interference generated by USB3.0 high-frequency communication is a broadband interference that cannot be eliminated...
