Speaking right distribution method in group calling service, cluster core network and dispatching desk

Abstract

The embodiments of the invention provide a speaking right distribution method in a group calling service, a cluster core network and a dispatching desk. The distribution method comprises the followingsteps of according to speaking right authorization confirmation information sent by the dispatching desk, starting a time limit timer corresponding to the speaking right of the dispatching desk in abroadband cluster communication system and sending the occupation information of the speaking right to other user terminals in a group where the dispatching desk is located; and after the time limit timer ends timekeeping, sending speaking right prompting information to the dispatching desk so that the dispatching desk acquires the residual occupation time of the speaking right according to the speaking right prompting information. In the invention, when the speaking right is about to be overtime, the dispatching desk is timely and accurately prompted, the speaking right of the dispatching desk can be intelligently distributed, and the communication stability and the reliability of the group calling service in a broadband cluster communication system are guaranteed.

Description

technical field [0001] The invention relates to the technical field of broadband trunking communication, in particular to a method for distributing speaking rights in a group call service, a trunking core network and a dispatching station. Background technique [0002] The broadband trunking communication system is developed to meet the command and dispatch needs of industry users, and is a dedicated wireless communication system for specific industry applications. The trunking communication system has a wide range of application markets in government departments, public safety, emergency communications, electric power, civil aviation, petroleum, ports and other fields. The broadband trunking communication system based on TD-LTE technology takes TD-LTE as the core technology, and integrates the high speed and large bandwidth of TD-LTE with the characteristics of resource sharing, fast call establishment, and command and dispatch in digital trunking technology. A communicati...

Problems solved by technology

[0004] In the current discourse right allocation process, there is no notification mechanism for the discourse authority between the dispatcher and the cluster core network. The cluster core network cannot notify the dispatcher that the discourse right is about to time out, which also causes the dispatcher to be unable to execute the discourse right. Renewal: If the time that the dispatcher occupies the right to speak exceeds the duration of the right to speak, that is to say, in the process of allocating the right to speak, the right to speak can only be obtained by re-initiating the application process for the right to speak after the right to speak is forcibly released. The renewal of the right to speak is triggered during the aging process of the right to speak, and for users in industries with high real-time scheduling requirements such as public security and fire protection, it will seriously affect the effectiveness and real-time performance of dispatching and commanding
