Embodiment Construction

[0018] The present invention is applied to a cluster system, and the architecture of the cluster system is as follows figure 1 As shown, it includes a core network 11, a bearer network 12, a base station 13 and a terminal 14, wherein the core network 11 is connected to multiple base stations 13 through the bearer network 12, and the bearer network 12 may specifically be an IP bearer network. The trunking system may be a broadband trunking system, such as an LTE (Long Term Evolution, Long Term Evolution) broadband trunking system, or a narrowband trunking system such as a PDT (Professional Digital Trunking, dedicated digital trunking) trunking system.

[0019] In different cluster systems, the core network 11 may have different core network devices. For example, in an LTE broadband trunking system, the core network 11 may include eMME (enhanced Mobility Management Entity, enhanced mobility management entity), TCF (Trunking Control Function, cluster control function module), eHS...

Abstract

The invention discloses core network equipment and a trunking communication method thereof. The trunking communication method comprises the steps that after the core network equipment conducts media negotiation after receiving a speaking right request sent by a user terminal; the core network equipment adds the speaking right application into a speaking right application queue to queue and sends a response message containing a speaking right queueing notification and a media negotiation result to the user terminal; and when the speaking right application sent by the user terminal queues to the front end of the speaking right application queue, the core network equipment sends speaking right authorization to the user terminal to enable the user terminal to conduct trunking communication. In this way, the trunking communication method has the advantages that when the speaking right application queues to the front end of the queue, speaking right authorization can be achieved immediately, the signaling procedures are decreased, time is saved, and the trunking communication process is accelerated.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a core network device and a cluster communication method thereof. Background technique [0002] The trunking communication service refers to the trunking communication network composed of the trunking communication system with technical characteristics such as channel sharing and dynamic allocation, and provides dedicated command and dispatching and other communication services for group users such as multiple departments and units. The trunking communication system is an advanced mobile dispatching system, which represents the development direction of a dedicated mobile communication network, one of the communication systems. [0003] In trunking communication, when there are too many terminals applying for the speaking right service, queuing is often required. In the existing speaking right application queuing technology, when a terminal applies for the speaking right, i...
