Multicast Group Processing for Air Interface Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing network data processing technologies, when multiple terminals request the same network data, duplication of data occurs, leading to inefficient use of communication and air interface resources, resulting in resource waste.
Innovation Solution
Implementing a multicast group processing method where terminals are grouped based on channel requests, allowing data to be delivered using a single air interface resource and communication resource, with each terminal in the group decoding the data using a group scheduling identifier, and dynamically managing resources based on channel quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network data is duplicated for multiple terminals requesting the same channel, then each terminal can receive data independently, but transmission resources are wasted due to redundant data delivery
Solution Approach 1:
The patent merges multiple unicast data delivery operations into a single multicast data delivery operation. When multiple terminals request the same network data, the gateway creates a multicast group and delivers one copy of the data to all group members simultaneously, eliminating redundant transmissions and saving transmission resources while ensuring reliable delivery to all terminals.
2Loss of energy
If multicast group is implemented for multiple terminals, then transmission resources are saved, but device complexity increases due to group management overhead
Solution Approach 1:
The gateway implements a universal multicast group management mechanism that handles multiple terminals' data requests through a unified process. The same multicast group creation and data delivery procedure is applied regardless of the number of terminals, making the system scalable and reducing per-terminal management complexity while improving transmission efficiency.

AI summary
The present disclosure relates to network data processing methods and apparatus. One example method includes receiving a multicast group join request sent by a terminal, adding a terminal identifier to a multicast group corresponding to a target channel identifier, where the multicast group corresponding to the target channel identifier includes an identifier of a terminal that has requested network data corresponding to the target channel identifier, and delivering the network data based on the multicast group and a group scheduling identifier corresponding to the multicast group by using an air interface resource corresponding to the multicast group, where a terminal in the multicast group decodes the air interface resource based on the group scheduling identifier to obtain the network data.
