Method for transmitting monitoring videos in real time in broadband digital clustering communication system

Abstract

The invention relates to a method for transmitting monitoring videos in real time in a broadband digital clustering communication system, which comprises the following steps: a terminal sends a monitoring video request message to a network subsystem; the network subsystem authenticates the terminal, interacts with an information application subsystem to generate quality of service (QoS) policies,and allocates clustering specially-loaded QoS parameters; the network subsystem sends the clustering specially-loaded QoS parameters to a broadband wireless access subsystem, and the broadband wireless access subsystem allocates downlink resources and sends the downlink resources to the user terminal; the user terminal completes the configuration of each layer according to the description of the downlink resources; the broadband wireless access subsystem sends clustering contexts to the network subsystem to establish a completion message; and the information application subsystem interacts with the network subsystem and sends business data streams of the monitoring videos to the user terminal through the network subsystem and the broadband wireless access subsystem. After the embodiment of the invention is applied, the high rate and low time delay of real-time transmission of the monitoring videos can be guaranteed, thereby providing the QoS guarantee.

Description

technical field [0001] The present invention relates to the field of communication technology, more specifically, to a method for real-time transmission of monitoring video in a broadband digital trunking communication system based on Time Division Long Term Evolution (TD-LTE, Time Division-Long Term Evolution) technology. Background technique [0002] The digital trunking communication system is a mobile command and dispatch system, which plays a huge role in the field of professional communication. Compared with the public mobile communication system, the digital trunking communication system supports private calls and group calls, and the call connection is fast, and the users in the group share the downlink business channel, which has a high spectrum utilization rate. [0003] Due to its unique characteristics of dispatching, group calling and fast calling, the digital trunking communication system has played a huge role in the field of professional communication. Since...

Problems solved by technology

However, with the advancement of information technology and the vigorous development of Internet applications, the business requirements of trunking users in various industries, enterprise users, and government departments for digital trunking communication systems are gradually shifting from ordinary dispatching voice to integrating voice, data, image and The direction of broadband multimedia integrating video is changing. It is hoped that the broadband digital trunking communication system with high speed, low delay, and quality of service (QoS) can be used to improve work efficiency and speed up informatization construction. However, the existing digital trunking communication system is still Unable to provide real-time transmission of broadband multimedia services, surveillance video, etc.
