Group-Based Data Routing to Cut Mobile Signaling Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data transmission architectures result in high signaling overheads due to frequent creation and release of channels between terminal devices and user plane functions as they move, leading to inefficient resource utilization.
Innovation Solution
Implementing a data transmission method that manages channels based on terminal groups rather than individual devices, using a routing device to store and forward data packets associated with a group, thereby reducing the need for frequent channel creation or release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If channels are managed based on individual terminal devices, then each terminal device can have dedicated channel control, but signaling overheads increase due to frequent channel creation and release as devices move
Solution Approach 1:
The patent merges multiple terminal devices into a terminal group with a common channel between the access network device and the routing device. This combining approach allows shared channel resources among group members, eliminating the need for individual channel creation and release for each device, thereby reducing signaling overhead while maintaining operational control.
2Stability of the object's composition
If fixed channels are established between terminal devices and user plane functions, then channel stability is improved, but resource utilization decreases due to inability to adapt to device movement
Solution Approach 1:
The patent introduces dynamic channel management at the terminal group level, where the channel between the access network device and routing device can be dynamically established, maintained, or released based on the collective movement and activity of terminal devices in the group. This dynamic approach maintains channel stability for active groups while improving resource utilization by releasing channels when groups become inactive or move out of service areas.

AI summary
This application discloses a data transmission method and a communication apparatus. The data transmission method includes: The access network device receives a first data packet from a first terminal device, where the first data packet is associated with a terminal group, the terminal group including the first terminal device. The access network device sends the first data packet to a first routing device for forwarding. The first routing device corresponds to the terminal group. The first routing device stores routing information of one or more respective terminal devices of the terminal group. The routing information is for forwarding the first data packet. Signaling overheads can be reduced by using embodiments of this application.
