Problems solved by technology
[0005] However, the group call and video transmission control under the MCVideo system launched by 3GPP are mainly for the public safety network, while the railway mobile communication network has its specialization and particularity, and there are certain differences from the public safety network; in addition, the railway trunking communication and The application scenarios of dispatching communication services are special, therefore, the MCVideo mechanism in the 3GPP standard cannot be applied

The invention discloses a method for controlling group calling video transmission of a railway MCVideo system, which can meet the authority control requirements of various user terminals in the application scene of railway trunking communication and dispatching communication services, is beneficial to more reasonable application of railway private network resources, and can ensure the feasibility, controllability and high efficiency of video transmission in railway video group calling. Specifically, different video transmission permissions can be respectively configured for different types of user terminals according to characteristics and application strategies of the user terminals, and a more perfect video sending control, transmission notification and receiving control method (collectively referred to as a video transmission control method) is provided on this basis. Through the user video transmission permission configuration and video transmission control method, the railway clustering and dispatching communication application requirements are greatly met, and the command and communication efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of railway wireless communication, in particular to a method for controlling group call video transmission in a railway MCVideo system. Background technique [0002] With the continuous research and advancement of railway mobile communication technology towards broadband and intelligence, my country's railways have now made it clear that 5G-R will be used to realize the next-generation railway mobile communication system. [0003] The International Organization for Standardization 3GPP (3rd Generation Partnership Project) standard has successively launched a series of standards based on key business communication mechanisms: MCPTT (critical voice communication), MCData (critical data communication) and MCVideo (critical video communication), the above three are collectively referred to as For MCX (critical business communication), they become the main development direction of future trunking communication. ...
