Core Network User Plane Element Multicast Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multicast communication, the mobile network experiences resource wastage due to the replication of multicast data across multiple intermediate devices, leading to inefficient data transmission.
Innovation Solution
A method where the core network user plane element establishes data connections with terminals and selectively transmits multicast data through a designated first data connection, reducing redundant data transmission and alleviating load on network elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multicast data is replicated and transmitted through multiple data connections in the mobile network, then all terminals can receive the data, but transmission resources are wasted and intermediate devices transmit large amounts of repeated data
Solution Approach 1:
The patent merges multiple data connections into a single data connection for multicast data transmission. The core network user plane network element establishes multiple data connections to terminals but selects only one (the first data connection) for transmitting multicast data, combining the function of multiple connections into a single efficient transmission path while maintaining reliable data delivery to all terminals in the multicast group
Solution Approach 2:
The patent extracts the essential function of multicast data transmission from the multiple data connections and concentrates it into a single selected data connection. By determining a first data connection from the plurality of data connections and sending multicast data only through this first data connection, the system removes redundant transmission paths and eliminates wasted transmission resources
2Adaptability or versatility
If multicast data is transmitted through multiple data connections, then all terminals can be served, but the load on core network user plane network element increases
Solution Approach 1:
The patent combines the service function for multiple terminals into a single data connection. The core network user plane network element maintains multiple data connections for flexibility but consolidates the multicast data transmission through one selected first data connection, thereby serving all terminals while reducing the processing load on the network element
Solution Approach 2:
The patent extracts the multicast data transmission function from the set of multiple data connections and isolates it in a single first data connection. This extraction reduces the computational burden on the core network user plane network element by avoiding the need to process and manage data transmission across multiple connections simultaneously

AI summary
This application provides a method and an apparatus for sending multicast data. The mobile network includes a core network, and the method includes: A core network user plane network element establishes a plurality of data connections to a terminal. The core network user plane network element determines a first data connection, where the plurality of data connections include the first data connection. The core network user plane network element receives multicast data sent to the terminal. The core network user plane network element sends the multicast data to an access network element through the first data connection. The first data connection is a part of the plurality of data connections. The core network user plane network element sends the multicast data to the terminal through the part of the plurality of data connections. This reduces redundant multicast data transmitted in the core network, so that a waste of transmission resources is avoided.
