specific Embodiment approach 1

[0017] Specific implementation mode one, combine figure 1 Describe this embodiment mode, the broadband multimedia trunking system based on TD-LTE, it comprises terminal 1, broadband wireless access subsystem 2, network subsystem 3 and operation and maintenance subsystem 4,

[0018] The terminal 1 includes a handheld mobile station 101, a vehicle-mounted station 102, a fixed station 103, a wireless dispatcher 104 and a plurality of DC wired dispatchers 105,

[0019] The broadband wireless access subsystem 2 is composed of multiple eNodeB evolved base stations 201, and the multiple eNodeB evolved base stations 201 are connected through the X2 interface. The RTDF wireless cluster scheduling function entity 202 is integrated in the eNodeB evolved base station 201. The RTDF The wireless trunking scheduling function entity 202 is responsible for trunking processing of trunking services;

Abstract

The invention discloses a realization method of a speaking right signaling of a broadband multimedia cluster system dispatching station based on TD-LTE (Time Division Long Term Evolution), which relates to a realization method of a speaking right signaling of a broadband multimedia cluster system dispatching station and solves the problems of low efficiency and easy mistake making of the traditional digital cluster technology. The realization method of the speaking right signaling is completed on the basis of a broadband multimedia cluster system. The system comprises a terminal connected with a broadband wireless access subsystem through an LTE-Uu (Long Term Evolution User to User) interface, the broadband wireless access subsystem is connected with a network subsystem through an S1-MME (Mobility Management Entity) interface, and the network subsystem and the broadband wireless access subsystem are connected with an operation maintenance subsystem. The specific procedures of the realization method are as follows: when group calling is established, a DC (data center) sends a speaking right application request to a TDS (Transaction Data Set), and the TDS replies a speaking right application response to inform the DC whether the speaking right is granted; when the DC owns the speaking right and conversation is finished, the DC sends a speaking right release request to the TDS, and the TDS releases the speaking right and returns a speaking right release response to the DC. The invention can satisfy the application requirements of commanding and dispatching.

Description

technical field [0001] The invention relates to a method for realizing speech right signaling of a broadband multimedia trunking dispatching station. Background technique [0002] With the development of society and economy, especially with the rapid development of public mobile communications, government departments, enterprises and institutions have increasingly extensive and urgent needs for trunking systems with team command and dispatch functions. The cluster system is widely used in my country's large-scale enterprises and institutions, administrative law enforcement and other industries, and plays an active role in guaranteeing its production command and dispatch. Although these trunking systems have played a positive role, there are also many disadvantages, mainly in the fact that most of the trunking systems currently in use are analog technologies, and analog trunking systems have shortcomings such as large interference, many blind spots, and limited frequencies. ...
