The embodiment of the invention discloses a data transmission method of a multicast service, related equipment and related equipment, which are used for solving the problems of how to transmit a datapacket of the multicast service in a 5G system and how to guarantee the service quality of the multicast service in the prior art. The method provided by the embodiment of the invention comprises thefollowing steps: a first network element receives a first request message from first terminal equipment, the first request message is used for requesting multicast service, and the first request message comprises identification information of the first terminal equipment and / or identification information of the multicast service; and the first network element acquires a first QoS strategy corresponding to the multicast service, so that a data packet of the multicast service is transmitted on a unicast tunnel between a second network element and a third network element according to the first QoS strategy.
Description
technical field [0001] The present application relates to the field of communications, and in particular to a data transmission method for a multicast service and related equipment. Background technique [0002] Compared with unicast and broadcast, multicast, also known as multicast, can efficiently solve the problem of point-to-multipoint transmission and distribution. In a multicast scenario, data can be sent to a group of users along a specific path, and there is at most one copy of the same multicast data on each link. For example, for some services such as Internet Protocol Television (IPTV), the contents of the packets sent by the server to different users are the same, such as Figure 1a As shown, in the unicast mode, the server needs to copy the packets for different users and send them to the corresponding users respectively; while in the multicast mode, the server only needs to send a packet for each downstream routing device joining the multicast group. Then, the...
