Method for realizing trunking traffic and trunking user terminal

Abstract

The invention discloses a method for realizing trunking traffic and a trunking user terminal. The method is realized in a digital trunking communication system based on a time division long term evolution (TD-LTE) technique. In the digital trunking communication system based on the TD-LTE technique, a logical channel and a transmission channel which are used for realizing the trunking traffic arenewly added, wherein the logical channel is a trunking paging control channel (TPCCH) and a trunking traffic channel (TTCH), the transmission channel is a trunking paging transmission channel (TPCH),and identifications and mapping approaches which are used for distinguishing the logical channel from the other logical channels are respectively defined for the TPCCH and the TTCH. Through the TPCCH, paging and control messages, such as the call setup, the call release, the discourse right notice and the like of the trunking traffic, are loaded. Through the TTCH, the data messages of the trunking traffic are loaded. By applying the scheme of the invention, call setup time can be shortened, and resource utilization ratio can be increased.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method for implementing trunking services in a digital trunking communication system based on Time Division-Long Term Evolution (TD-LTE, Time Division-Long Term Evolution) technology and a trunking user terminal. 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. Existing digital trunking communication systems mainly include: TETRA (Terrestrial Trunked Radio) system, integrated digital enhanced network (iDEN, Integrated Digital Enhanced Networks) system, open trunking architecture (GoTa, Global Open Trunking Architecture) system And GT800 syst...

AI Technical Summary

Problems solved by technology

Since the existing digital trunking communication systems are mostly based on Global System for Mobile Communications (GSM, Global System for Mobile Communications) or Code Division Multiple Access (CDMA, Code Division Multiple Access) technology, the base station needs to be controlled uniformly by the base station controller, which cannot communicate with the core Therefore, there are many signaling interactions during the establishment of trunking services such as group call service and broadcast call service, which in turn leads to prolonged call establishment time.

In addition, in the existing digital trunking communication system, trunking services are all carried in the circuit domain, so the sharing of service channels cannot be realized, resulting in reduced resource utilization
