Problems solved by technology

Since the existing digital trunking communication systems are mostly implemented based on Global System for Mobile Communications (GSM, Global System for Mobile Communications) or Code Division Multiple Access (CDMA, Code Division Multiple Access) technology, base stations need to be controlled uniformly by base station controllers, which cannot communicate with the core network Direct communication, so ther

Embodiment Construction

[0047] Aiming at the problems existing in the prior art, the present invention proposes a brand-new trunking service implementation scheme, which introduces TD-LTE technology into the digital trunking communication system, thereby obtaining a digital trunking communication system based on TD-LTE technology, and based on The digital trunking communication system realizes trunking services.

[0048] figure 1 It is a schematic diagram of the network architecture of the existing digital trunking communication system based on TD-LTE technology. Such as figure 1 As shown, it includes: trunking user terminals, trunking broadband wireless access subsystems, and trunking network subsystems.

[0049] Among them, the trunking user terminal is connected to the trunking broadband wireless access subsystem or the trunking network subsystem through an air interface, etc., to provide users with various push-to-talk (PTT, Push-To-Talk) voice services, broadband trunking multimedia services a...

Abstract

The invention discloses a trunked service implementation method, comprising: a trunked user terminal detects whether dispatching information of a TPCCH (trunked paging control channel) exists periodically; if so, a TB (transmission block) containing information borne by the TPCCH is searched, and the TB is decoded to acquire the information borne by the TPCCH; a user terminal detects the PDCCH (physical downlink control channel) in each TTI (transmission time interval), searches the TB of the borne information, successfully decodes as well as configures and establishes a service plane channel; a calling trunked user terminal adopts the established service plane channel to initiate a conservation; and a called trunked user terminal detects the PDCCH in the TTI, searches the TB of the information borne by a TTCH (trunked traffic channel), and decodes the searched TB. The invention also discloses a trunked user terminal. After the embodiment of the invention is applied, the time for establishing a calling is shortened, and the resource utilization rate is improved.

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: Terrestrial Trunked Radio (TETRA, Terrestrial Trunked Radio) system, Integrated Digital Enhanced Networks (iDEN, Integrated Digital Enhanced Networks) system, Open Trunking Architecture (GoTa, Global Open Trunking Architec...
