Embodiment Construction

[0022] Aiming at the problems existing in the prior art, the present invention proposes a new broadband digital trunking communication system, which is implemented based on TD-LTE technology.

[0023] TD-LTE technology is a model for the integration of mobile communication and broadband wireless access, and it is also one of the mainstream standards for future broadband mobile communication. The broadband digital trunking communication system based on TD-LTE technology will inherit many advantages of TD-LTE technology such as high speed and large bandwidth. Compared with the existing narrowband digital trunking communication system, it has larger channel capacity and higher spectrum utilization. rate, stronger anti-interference ability and better transmission performance, and has incomparable advantages in the autonomy of system research and development with other broadband wireless technologies.

[0024] In addition, the broadband digital trunking communication system of the ...

Abstract

The invention discloses a broadband digital trunked communicated system which is realized on the basis of a long term evolution technology of a time division duplex (TD-LTE). A multimedia trunked scheduling subsystem and the required interfaces and a signaling process are added so as to realize related trunking functions, the change of the architecture of the existing TD-LTE system, each network element function, the interface and the signaling process is very small, and therefore the realization of the product is relatively simple, the cost is low, and the communication system is very good in portability and extendibility.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a broadband digital trunking communication system. Background technique [0002] The trunking communication system is a dedicated wireless communication system for industry applications developed to meet the needs of industry command and dispatch. Similar to the public mobile communication system, the trunking communication system has also experienced the development process from the first generation analog trunking communication system to the second generation narrowband digital trunking communication system. [0003] The narrowband digital trunking communication system is currently the most widely used trunking communication system, which represents the Terrestrial Trunked Radio (TETRA, Terrestrial Trunked Radio) system defined by the European Telecommunications Standards Institute (ETSI, European Telecommunications Standards Institute) and the comprehensive digital trunking s...
