Abstract

The invention discloses a broadband multimedia cluster architecture system based on TD-LTE (Time Division Long Term Evolution), which relates to a broadband multimedia cluster architecture system and solves the problems of low efficiency and easy mistake making of the traditional digital cluster technology. The broadband multimedia cluster system comprises a terminal, a broadband wireless access subsystem, a network subsystem and an operation maintenance subsystem. The terminal comprises a handheld mobile station, a vehicle mounted station, a fixed station, a wireless dispatching station and a plurality of DC (data center) wired dispatching stations. The broadband wireless access subsystem comprises a plurality of eNodeB evolutionary base stations. The terminal is connected with the broadband wireless access subsystem through an LTE-Uu (Long Term Evolution User to User) interface, the broadband wireless access subsystem is connected with the network subsystem through an S1-MME (Mobility Management Entity) interface, and the network subsystem and the broadband wireless access subsystem are connected with the operation maintenance subsystem. The invention can satisfy the application requirements of commanding and dispatching.

Description

technical field [0001] The invention relates to a broadband multimedia trunking system. 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. The traditional digital trunking system can well support the v...
