Problems solved by technology

[0004] The difference between the data transmission in the mobile network and the data transmission in the fixed network is that the transmission equipment in the fixed network usually forwards the data hop by hop according to the destination address of the data. After the data arrives at the transmission equipment closest to the terminal, the transmission equipment It is directly forwarded to the terminal; and the transmission mechanism of the mobile network becomes more complicated due to the mobility of the terminal. After the data reaches the connection device, it needs to go through the data connection carried by multiple intermediate devices to reach the terminal. The data connection is the terminal. Dedicated data channel, therefore, a piece of multicast data needs to be copied into multiple copies at the connecting device, and sent to multiple terminals through the data connection of each terminal, so that the intermediate equipment of the mobile network transmits a large amount of repeated multicast data. Caused a waste of transmission resources of the mobile network

Abstract

The invention provides a method and device for sending multicast data. A mobile network comprises a core network, and the method comprises the following steps that a core network user plane network element establishes a plurality of data connections with a terminal; the core network user plane network element determines a first data connection, wherein the plurality of data connections comprise the first data connection; the core network user plane network element receives multicast data sent to the terminal; and the core network user plane network element sends the multicast data to the access network element through the first data connection. The first data connection is partial data connection in the plurality of data connections, and the core network user plane network element sends the multicast data to the terminal through the partial data connection in the plurality of data connections, thereby reducing the redundant multicast data transmitted in the core network, and avoiding the waste of transmission resources.

Description

technical field [0001] The present application relates to the field of communications, and in particular, to a method and apparatus for sending multicast data. Background technique [0002] Multicast communication is a communication technology that can save bandwidth. When a multicast source device sends data to multiple target devices in a multicast group, only one piece of data is transmitted, and the transmission device (for example, a router) close to the target device receives the data. After the data is received, the data is copied and distributed to multiple terminals respectively. Since only one piece of data is transmitted between the multicast source device and the transmission device, multicast communication can save transmission bandwidth. [0003] In the combined fixed network and mobile network, the fixed network is usually used as the communication network between the multicast source device and the transmission device, and the mobile network is usually used a...
