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.
