Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0030] At present, frequency hopping is used to solve the interference of MIPI signal transmission on the radio frequency communication system in the terminal equipment. Specifically, the MIPI frequency hopping scheme includes: according to the communication frequency band of the current terminal equipment (for example: network frequency band, frequency point, channel, etc.), several preset fixed clock signals (clock, CLK) are adjusted in real time, so ...

Abstract

The embodiment of the invention discloses a data transmission control method, a data transmission control device and terminal equipment. The method comprises the following steps: acquiring a channel bandwidth contrast value of a working frequency band of the terminal equipment; determining a target bandwidth according to the channel bandwidth contrast value, the target bandwidth being greater thanor equal to the channel bandwidth contrast value; taking the target bandwidth as an adjustment base number, and adjusting the adjustment parameter until the transmission frequency of the mobile industry processor interface MIPI is not overlapped with the working frequency band, the transmission frequency corresponding to the adjustment parameter; and determining a data transmission mode of the MIPI according to the transmission frequency. By utilizing the embodiment of the invention, the problem that the traditional MIPI cannot avoid various communication frequency bands at the same time, sothat the MIPI interferes with a communication system, and the communication performance of the terminal equipment is influenced can be solved.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and in particular, to a data transmission control method, device, and terminal equipment. Background technique [0002] With the continuous development of communication and terminal technologies, terminal equipment has more and more functional components, and these functional components will cause great interference to the radio frequency communication system in the terminal equipment. For example, the terminal device will transmit data between the peripheral devices (such as cameras and LCD screens) that support the Mobile Industry Processor Interface (MIPI) protocol and the terminal device. During this process, the MIPI signal is easily affected by the radio Communication systems cause interference when sending and receiving signals. [0003] At present, the traditional MIPI adopts a preset fixed clock frequency, so that it avoids the transceiver frequency band of the radio freq...
