Abstract

The invention relates to a data transmission method, device and system, multicast management equipment and user equipment, and relates to the technical field of communication. The method comprises: establishing a signaling multicast channel and a data multicast channel; initiating signaling multicast through the signaling multicast channel, so that each user equipment joining in the multicast group of signaling multicast judges whether to join in the multicast group of data multicast corresponding to signaling multicast or not according to the message of signaling multicast; and initiating data multicast through the data multicast channel, so that the user equipment joining in the multicast group of the data multicast acquires the data packet from the message of the data multicast. According to the technical scheme, the data transmission efficiency can be improved.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a data transmission method, a data transmission device, a data transmission system, a multicast management device, user equipment, and a computer-readable storage medium. Background technique [0002] The data distribution and reception technology is applicable to various service applications. For example, the IPTV (Interactive Personality Television, Interactive Internet Television) set-top box upgrade can be realized through the data distribution and reception technology. [0003] In related technologies, data distribution and reception are realized through unicast transmission. For example, multiple IPTV set-top boxes can be upgraded through unicast transmission. Contents of the invention [0004] The inventors of the present disclosure found the following problems in the above-mentioned related technologies: when the number of concurrent users increa...
