Mobile communication system capable of information data transfer function and method thereof

Abstract

The present invention provides one kind of mobile communication system and method possessing information data transmitting function. The system includes several mobile communication terminals to create, transmit and receive information data including moving image; and several radio communication terminals to transmit and receive the information data in FM mode and modulate and demodulate before transmitting to the mobile communication terminals. By means of the mobile communication system and method possessing information data transmitting function, the information data created in the mobile communication terminals may be transmitted to military radio communication network to raise combat command efficiency.

Description

technical field [0001] The invention relates to a mobile communication system, in particular to a mobile communication system with information data transmission function and its method. Background technique [0002] The radio transceiver wirelessly transmits and receives voice signals converted into FM (Frequency Modulation) modulated signals. When the frequency is adjusted to the frequency that the FM receiver can receive, the radio transceivers with the same frequency can send and receive signals, but when multiple users send together, they cannot receive the voice clearly. At this time, they can only be changed. used by frequency. [0003] Before the radio transceiver receives a call from the other party, that is, when there is no signal in the frequency band set by itself, it is in the standby mode with the power supply minimized, and starts talking when the signal in the frequency band gradually increases. That is, when there is no signal, turn off the speaker, otherw...

AI Technical Summary

Problems solved by technology

[0004] The use of a unidirectional half-duplex or a bidirectional full-duplexer is determined by using one channel for sending and receiving or using the sending channel and receiving channel respectively, that is, channels of different frequencies are used for two-way communication , one-way communication uses the same frequency to send and receive, so the circuit is simple, but it can only be sent or received once

[0005] The existing military wireless communication is a voice-based communication network, which cannot transmit moving images or photos of the battlefield or mission execution, so the commander cannot accurately grasp the current situation of the battlefield

[0006] Moreover, in order to transmit a text message with a code content, a cryptic table is used to convert the code number into a voice and transmit it or use a bulky security device, so there are problems that it is inconvenient to carry and the corresponding operations cannot be quickly processed by the communication soldiers.
