Abstract

The invention discloses digital trunking communication system and method based on a VSAT satellite land station. Soft exchange of communication modes of a VSAT satellite communication network and different digital trunking systems is realized by land interface units of interconnection of a VSTA satellite communication system and the digital trunking systems, thereby realizing remote interconnection of different types of digital trunking systems. The invention has the advantages of wide coverage range, wide service range, multiple service functions, complete managing and scheduling functions, high resource utilization ratio, high networking speed and low maintenance cost.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a communication system and method for interconnecting digital trunking systems based on VSAT satellite ground station switching technology. Background technique [0002] The digital trunking communication system is a high-efficiency and cheap advanced dedicated advanced mobile command and dispatch mobile communication system. The limited communication channels of the trunking communication system are automatically, dynamically and optimally assigned to all users in the system under the control of the central console. It is especially suitable for the unified dispatch and emergency communication of the military, enterprises, and government departments. There are several TETRA and iDEN digital trunking communication systems in operation in China, which can be adapted to the fixed public network. Since different digital trunking communication systems have different...
