Method for achieving video scheduling

Abstract

The invention provides a method for achieving video scheduling, which is achieved based on a TD-LTE (Time Division Long Term Evolution) broadband digital trunked communication system. The system comprises a terminal, a broadband wireless access subsystem, a network subsystem, a multimedia cluster scheduling subsystem and an operation maintenance subsystem. The method comprises the following steps that: the terminal requests video scheduling business to the multimedia cluster scheduling subsystem; the multimedia cluster scheduling subsystem authenticates the terminal according to the request, and indicates the network subsystem to initiate a video scheduling business establishing process; the network subsystem initiates a cluster bearing establishing process according to the indication, and completes the establishment of the cluster bearing together with the broadband wireless access subsystem; the network subsystem determines the establishment of the video scheduling business to the multimedia cluster scheduling subsystem; and the multimedia cluster scheduling subsystem determines the establishment of the video scheduling business to the terminal. By using the method, the real-time transmission of the video scheduling business can be achieved.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a method for realizing video scheduling. Background technique [0002] The 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 has the characteristics of fast call connection, high safety and reliability, and high resource utilization rate, and is especially suitable for command and dispatch. Since the mid-1990s, the digital trunking communication system has risen in the world, has been widely used, and has achieved good economic and social benefits. At present, the widely used digital trunking communication systems in China include TETRA, iDEN, GoTa, GT800 and so on. [0003] The comprehensive advancement of informatization has prompted users in the trunking industry to not only be satisfied wi...

Problems solved by technology

Due to the limitations of bandwidth and data transmission rate, several existing digital trunking communication systems can only provide voice scheduling services and some low-speed data services, and cannot realize real-time transmission of video scheduling services, that is, it is difficult to provide services such as on-site video backhaul , video call and video surveillance and other video dispatching services

If the video network is built separately, or the existing public broadband wired / wireless network is used to transmit the video dispatching service, not only the network construction cost is high, the security and confidentiality are poor, but also it cannot be compatible with the trunking communication system, which is not conducive to centralized control and dispatching
