specific Embodiment approach 1

[0013] Specific implementation mode 1. Combination 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,

[0014] The terminal 1 includes a handheld mobile station 101, a vehicle-mounted station 102, a fixed station 103, a wireless dispatcher 104 and at least one DC wired dispatcher 105,

[0015] The broadband wireless access subsystem 2 is composed of at least two eNodeB evolved base stations 201, each two eNodeB evolved base stations 201 are connected through an X2 interface, and each eNodeB evolved base station 201 is integrated with an RTDF wireless cluster scheduling function module 202. The RTDF wireless cluster scheduling function module 202 is used to be responsible for cluster processing of cluster services,

[0016] The handheld mobile station 101, the vehicle-mounted station 102, the fixed station...

specific Embodiment approach 2

[0035] Specific embodiment two, the present embodiment is the realization method of multi-dispatch station hierarchical scheduling of the broadband multimedia trunking system based on TD-LTE, and its process is as follows:

[0036] The level and authority settings of the DC wired dispatcher 105 are saved on the HSS home domain signing server 302. When the DC wired dispatcher 105 initiates a dispatch operation, the TDS cluster dispatcher 303 obtains the DC wired dispatcher 105 in the HSS home through the D6a interface. information on the domain subscription server 302, and judge whether the DC cable dispatcher 105 can perform the dispatching operation through the obtained information, and its judgment criterion is:

[0037] 1. When there is only one DC wired dispatcher 105 in the dispatching operation, the TDS cluster dispatching server 303 judges whether to allow the DC wired dispatcher 105 to perform the dispatching operation through the dispatching authority of the DC wired d...

specific Embodiment approach 3

[0042] Specific embodiment three, the further description of this embodiment and specific embodiment two, the level and authority setting of DC wired dispatching station 105 are as follows:

[0043] A. The dispatching level of the DC cable dispatching station 105 is:

[0044] According to different user needs, the DC cable dispatching station 105 is rated as one to five levels, sorted in order, the first level is the lowest level, and the fifth level is the highest level;

[0045] B. The dispatching authority of the DC cable dispatching station 105 is:

[0046] 1) Called: the user can be called by some authorized users;

[0047] 2) Group call: an authorized user calls all users in the talk group;

[0048] 3) Team call: an authorized user calls all users in the call team;

[0049] 4) Single call: the user can choose any wireless user machine in the system as the call object for one-to-one communication;

[0050] 5) All calls: the dispatcher can call all users in the entire ...

Abstract

The invention provides a time division-long time evolution (TD-LTE)-based wideband multimedia cluster system and a method for implementing hierarchical dispatching of multiple dispatcher stations. The invention relates to a method for hierarchically dispatching by the multiple dispatcher stations, which solves the problem that the commanding and dispatching requirements of different industries are not conveniently met due to high cost and complicated setting of hardware configuration of the multiple dispatcher stations, and single dispatching mode of the multiple dispatcher stations in the conventional digital cluster technology. The system comprises a terminal, a broadband wireless access subsystem, a network subsystem and an operation maintenance subsystem. The method comprises the following steps that: as the level and authorization setting of a direct current (DC) cable dispatcher station are stored in a home subscriber server (HSS) attribution domain signing server, when the DC cable dispatcher station initiates primary dispatching operation, a Tivoli directory server (TDS) cluster dispatching server acquires information of the DC cable dispatcher station on the HSS attribution domain signing server through a D6a interface and judges whether the DC cable dispatcher station can perform the dispatching operation or not according to the acquired information. Therefore, the industrialization of broadband wireless access systems in China is greatly promoted.

Description

technical field [0001] The invention relates to a method for realizing hierarchical dispatching of multi-dispatching stations of a broadband multimedia cluster. 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 fre...
