Embodiment Construction

[0070] Aiming at the problems existing in the prior art, the present invention proposes a new digital trunking communication system, which is implemented based on TD-LTE technology. TD-LTE technology is a Time Division Synchronous Code Division Multiple Access (TD-SCDMA) evolution technology. It 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 digital trunking communication system based on TD-LTE technology will inherit many advantages such as high speed and large bandwidth of TD-LTE technology. Compared with the existing digital trunking communication system, it has larger channel capacity, higher spectrum utilization, Stronger anti-interference ability and better transmission performance can not only meet the needs of modern digital trunking communication systems such as large capacity, large bandwidth, high speed and high spectrum utilization, bu...

Abstract

The invention discloses a digital clustering communication system, in particular a digital clustering communication system based on a TE-LET technology, which is realized on the base of a time division-long term evolution technology and by expanding the functions of a certain network elements and adding new network elements of the prior TD-LTE technology. The invention also provides two clustering service implementation methods. The system and the methods not only can better provide broadband clustering multimedia services but also can backwards evolve smoothly.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a broadband digital trunking communication system based on Time Division-Long Term Evolution (TD-LTE, Time Division-Long Term Evolution) technology and a method for realizing trunking services. Background technique [0002] Due to its unique characteristics of dispatching, group calling and fast calling, the digital trunking communication system has played a huge role in the field of professional communication. Since the mid-1990s, the digital trunking communication system has risen in the world, has been widely used, and has achieved good economic and social benefits. [0003] Existing digital trunking communication systems mainly include: APCO25, Tetralpol, EDACS, DIMRS (iDEN), TETRA, IDRA, Geotek, and GoTa based on Code Division Multiple Access (CDMA) technology and GT800 based on Global System for Mobile Communications (GSM) technology Wait. The following briefly d...
