Portable satellite telephone voice communication terminal and method

Abstract

The invention discloses a portable satellite telephone voice communication terminal and method. The portable satellite telephone voice communication terminal comprises a satellite antenna, a satellite communication module, a control module, a tone coder-decoder and a telephone module, wherein the satellite antenna is used for outputting data of the portable satellite telephone voice communication terminal; the satellite communication module is used for establishing a voice call connection, coding and decoding a voice signal, and transmitting and receiving the voice signal; the control module is used for controlling modules in a coordinated way, and controlling call making and receiving; the tone coder-decoder is used for coding and decoding a dialing or incoming call number; and the telephone module is used for realizing a function of a telephone. The invention also discloses a portable satellite telephone voice communication method. Through adoption of the portable satellite telephone voice communication terminal and method, the problem of voice communication in geodetic networks of forests, deserts, oceans and the like and special environment areas which are not under the coverage of 2G / 3G / 4G is solved. The portable satellite telephone voice communication terminal and method play very important roles in field rescue and reporting.

Description

technical field [0001] The invention relates to a satellite phone voice communication terminal, in particular to a portable satellite phone voice communication terminal. Background technique [0002] my country's recent successful launch of the Tiantong-1 communication satellite is known as the "Chinese version of the maritime satellite." Its successful launch marks that my country has entered the mobile phone era of satellite mobile communication, filling the gap in the country. The technical indicators and capabilities of Tiantong-1 communication satellite have reached the level of the international third-generation mobile communication satellite, which can meet the diverse communication needs of users. Compared with the terrestrial mobile communication system, the mobile communication satellite system can achieve full coverage of the area from top to bottom, and is not affected by factors such as terrain. [0003] In the prior art, office work in areas with relatively h...

AI Technical Summary

Problems solved by technology

Traditional fixed-line telephones need switches to home lines, and need to deploy networks on the ground, but there are no such facilities in special environments such as forests, deserts, and oceans. Therefore, fixed-line telephones cannot be used for communication in these special environments; and for Devices that rely on 2G / 3G / 4G communication may not be covered by 2G / 3G / 4G communication networks in special environments such as forests, deserts, and oceans, and cannot perform mobile phone voice communication, and cannot communicate with external devices.

According to statistics, the national ground mobile communication coverage is less than 10% of the country's land area, and it is even more difficult to achieve full coverage of ground mobile communication in such a vast area as the South China Sea

[0004] Therefore, the use of terrestrial network and 2G / 3G / 4G network communication is very limited, and the coverage is not wide. Moreover, these communication devices have problems such as relying on the network deployment of the Telecom Union and the coverage of the base stations of the three major operators, large volume, and complex line equipment.
