Embodiment 1

[0032] figure 1 It shows the flow of a mobile terminal information transmission method provided by the first embodiment of the present invention, and only shows the part related to the embodiment of the present invention for convenience of description.

[0033] In step S101, the character information is encoded to generate encoded information.

[0034] In the embodiment of the present invention, the text information may be fixed text or text existing in the device, including letters, numbers or even symbols, etc., and the encoding method for encoding the text information is preset. This encoding mapping relationship is stored in the mobile terminal. For example, four numbers can be used to uniquely correspond to a character, or different combinations of dots and dashes can be used to uniquely correspond to different characters. This encoding method is not unique, as long as it meets the requirements of the encoding method All within the protection scope of the present inventi...

Embodiment 2

[0047] figure 2 It shows the flow of a mobile terminal information transmission method provided by the second embodiment of the present invention, and only shows the part related to the embodiment of the present invention for convenience of description.

[0048] In step S201, text information is acquired according to an input trigger signal.

[0049] In the embodiment of the present invention, the text information is fixed text, including letters, numbers, symbols, etc., and a trigger button is provided on the mobile terminal, and the trigger button can be a physical button or a virtual button on the screen. button, after the user has finished inputting a paragraph of text on the mobile terminal, by triggering the button, the mobile terminal can obtain the text information input by the user and prepare for subsequent information encoding; the text information can also be the text information preset by the mobile terminal, For example, for the SOS distress signal, the user do...

Embodiment 3

[0058] image 3 It shows that the third embodiment of the present invention provides a structure of an information transmission device for a mobile terminal, and only the parts related to the embodiment of the present invention are shown for convenience of description.

Abstract

The invention is applicable to the field of information transmission control, and provides a mobile terminal and a method and a device for information transmission of the mobile terminal. The method includes: coding text messages to generate coded information; and loading the coded information to a luminous element of the mobile terminal and sending out the same. If the coded information contained in light needs to be analyzed, the method further includes the steps: receiving the light and taking out the coded information contained in light by a light sensing element; and decoding the coded information into the text messages. The text messages are converted into the coded information according to a preset scheme, then the coded information is loaded onto the light for transmission, and since light is long in transmission distance and less susceptible to external interference and light transmission has directivity, the information can be only transmitted to a designated target receiver, and safety is high.

Description

technical field [0001] The invention belongs to the field of information transmission control, and in particular relates to a method and a device for information transmission and coded information transmission of a mobile terminal and a mobile terminal. Background technique [0002] In order to increase the confidentiality of information transmitted by mobile terminals, the information is usually encrypted and transmitted. In this way, the transmission of information requires a dedicated information encryption sending part and a corresponding information receiving and decrypting part. For example, existing mobile terminals can pass text information according to The predetermined encoding method controls the speaker to sound, and the microphone in the mobile terminal at the other end receives the sound and restores it into text information according to the predetermined decoding method. However, due to the limited range of sound transmission and the large signal attenuation, i...
