Data Forwarding Information Exchange for 5G Cell-Group Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communication systems, there is a challenge in efficiently forwarding uplink or downlink transmission data and selecting a transmission path to reduce data transmission delay during cell or cell group selective activation.
Innovation Solution
A method for transmitting data forwarding information is implemented by a first node, which sends data forwarding information to a second node based on a predetermined trigger event, enabling fast data transmission through negotiation between network nodes and updating pre-configured cell or cell group configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If data forwarding information is transmitted during cell or cell group selective activation, then data transmission delay is reduced, but transmission path selection complexity increases
Solution Approach 1:
The system pre-configures multiple transmission paths and data forwarding information before activation is needed. When cell or cell group selective activation occurs, the pre-configured paths enable immediate data forwarding without real-time path computation, thus reducing transmission delay while avoiding complexity during critical moments
Solution Approach 2:
A control node acts as an intermediary to manage transmission path selection and data forwarding information transmission. This intermediary handles the complexity of path selection centrally, allowing terminal devices to simply follow forwarding instructions, thereby reducing overall system complexity while enabling fast data transmission
2Speed
If multiple transmission paths are pre-configured for fast switching, then data transmission speed is improved, but system configuration complexity increases
Solution Approach 1:
Multiple transmission paths are pre-configured and stored in the system before activation events occur. This preliminary configuration allows instantaneous path switching during activation without real-time computation, achieving fast data transmission while confining configuration complexity to setup phase rather than operation phase
Solution Approach 2:
The system dynamically selects among pre-configured transmission paths based on activation events and current network conditions. This dynamic selection capability allows the system to adapt to different scenarios using multiple paths while maintaining manageable configuration complexity through standardized selection criteria
