Problems solved by technology

Since existing group call services are basically implemented in the digital trunking communication system based on the second generation mobile communication system (2G, 2nd Generation) or the third generation mobile communication system (3G, 3rd Generation), such as based on GSM technology For the GT800 system based on CDMA technology and the GoTa system based on CDMA technology, the base station needs to be uniformly controlled by the base station controller, and cannot directly communicate with the core network, so there are many signaling interactions during the group call establishment process, which increases the call establishment delay. ; In addition, the existing group call services are generally implemented in the circuit domain, and it is difficult to achieve a smooth backward evolution of the system

Embodiment Construction

[0023] The broadband wireless access subsystem consists of multiple enhanced eNodeBs (E-eNodeBs). The radio trunking dispatch function module (RTDF, Radio Trunking Dispatch Function) in the E-eNodeB is responsible for the related processing of the trunking service in the E-eNodeB, for example, receiving the trunking control from the enhanced mobility management entity (MME, Mobility Management Entity) (eMME) Signaling, which allocates downlink shared resources for the cell where the called terminal is located, and transmits the trunking service data stream received from the serving gateway (S-GW, Serving Gateway) to the called user terminal and the like.

[0024]The network subsystem includes eMME, S-GW, enhanced packet data network gateway (P-GW, PDN Gateway) (eP-GW), enhanced home subscriber server (HSS, Home Subscriber Server) (eHSS) and scheduling gateway ( D-GW, Dispatch Gateway). Among them, the trunking control function module (TCF, Trunking Control Function) in the eM...

Abstract

The invention discloses a group call business realizing method which is realized on the basis of a TD-LTE broadband digital trunking communication system to carry out network register and trunking business register when each user terminal in the system starts; when group call needs to be built, comprising: a calling user terminal sends a group call request to a network side to ask for building group call; the network side builds S5 / S8 load bearing for the call; the network side distributes uplink resource for the calling user terminal and builds a radio bearer and a S1 load bearing; at the same time, the network side distributes shared downlink resource to called user terminals belonging to the same district in all called user terminals corresponding to current call, and notices the called user terminals; the network side grants speech right to the calling user terminal and notices the called user terminals to finish building group call. If applied, the method of the invention can well shorten call building time delay and can progress smoothly and backwards.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method for realizing a group call service based on a Time Division-Long Term Evolution (TD-LTE, Time Division-Long Term Evolution) broadband digital trunking communication system. 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. In the existing digital trunking communication technology system, terrestrial trunking radio (TETRA, Terrestrial Trunked Radio) and integrated digital enhanced network (iDEN, Integrated Digital Enhanced Networks) are the most widely used. DivisionMultiple Access) open trunking architecture (GoTa, Global Open Trunking Archite...
