Mobile terminal and communication method thereof

Abstract

The invention discloses a mobile terminal and a communication method thereof. The mobile terminal comprises a main processor, and a wireless communication module and a visual intercom module which are connected with the main processor respectively, wherein the wireless communication module is used for performing wireless communication with a target mobile terminal through an external wireless network; the visual intercom module comprises a modulating and transmitting module and a frequency modulation receiving module; the modulating and transmitting module is used for receiving voice and video information of a user, performing frequency modulation on the voice and video information and transmitting the modulated information; and the frequency modulation receiving module is used for receiving the voice and video information which is modulated by the target mobile terminal and transmitted by the transmitting module, demodulating the voice and video information and playing the demodulated information. The mobile terminal can realize the switching of visual intercom on the basis of wireless communication so as to relieve the dependence on the wireless network and improve user experience.

Description

technical field [0001] The present invention mainly relates to the field of mobile communication, in particular to a mobile terminal and a communication method for the mobile terminal. Background technique [0002] With the rapid development of mobile communication technology and the improvement of people's living standards, mobile terminal devices such as mobile phones have become an indispensable device in daily work or life. At the same time, people have higher and higher requirements for mobile terminals. They not only want to be portable, but also want to integrate rich functions into a mobile terminal to adapt to the changing external environment. [0003] Existing mobile terminals such as mobile phones and MIDs (Mobile Internet Devices, Mobile Internet Devices) are usually connected to the mobile communication network through a mobile interface, receive signals from the mobile network, and communicate through the channel of the mobile network. Communication is bound ...

AI Technical Summary

Problems solved by technology

For example, in public places, a wireless network generally can only support a limited number of users to access the network at the same time in a certain coverage area. If there are many people making calls at the same time, some users will not be able to access the network normally.

In the blind areas of urban network coverage or in mountainous areas where there is no wireless network signal coverage or when the wireless network is abnormal, it is even more impossible to carry out wireless communication that relies on the wireless network. The connection brings great inconvenience, and even causes great losses to users

[0004] In the process of realizing the present invention, the inventor found that the prior art has at least the following defects: the current mobile terminals such as mobile phones or MIDs rely too much on wireless networks for communication, and there are inconveniences and defects in actual use.
