Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication networks face significant signaling overhead and access delay issues due to frequent connection establishment and release processes, particularly for UEs with static or low mobility and non-continuous data transmission needs, which are exacerbated by the increasing demand for real-time applications.
Innovation Solution
Implementing a light connection control method and apparatus that involves acquiring and utilizing light connection information to manage UE connections more efficiently, including identity, mobility area scope, and paging assistance, thereby optimizing paging and mobility control to reduce signaling overhead and access delay.

Engineering Contradiction Analysis
1Speed
If frequent connection establishment and release processes are implemented to meet real-time application demands, then responsiveness to real-time applications is improved, but signaling overhead increases
Solution Approach 1:
The system performs preliminary actions by establishing connections in advance for real-time applications and maintaining them in a suspended state rather than releasing and re-establishing them. The network side suspends connections proactively before they are needed again, preserving connection context and avoiding repeated establishment procedures, thus reducing signaling overhead while maintaining quick responsiveness.
Solution Approach 2:
The connection state is made dynamic by introducing a suspended state that allows flexible transitions between connected and disconnected states. The system can dynamically adjust connection status based on real-time application needs, switching to suspended state when connection is temporarily not needed but may be required soon, thereby optimizing the balance between responsiveness and signaling overhead.
2Productivity
If connection is released for UEs with static or low mobility, then resource utilization is improved, but access delay increases when reconnection is needed
Solution Approach 1:
The network performs preliminary suspension of connections for UEs with static or low mobility patterns, maintaining connection context in a suspended state rather than fully releasing it. This preliminary action allows the UE to quickly resume communication when needed without going through full reconnection procedures, thus reducing access delay while still freeing up resources for other uses.
Solution Approach 2:
The connection state parameter is changed from binary (connected/disconnected) to a three-state model (connected/suspended/disconnected). This parameter change enables the system to maintain a middle ground where resources are partially released but connection context is preserved, allowing fast reactivation for UEs that may need to reconnect soon, thereby reducing access delay while improving resource utilization.
3Reliability
If full connection establishment procedure is performed for each data transmission, then connection reliability is improved, but signaling overhead and access delay worsen
Solution Approach 1:
Instead of performing a full connection establishment procedure every time, the system applies partial action by using connection suspension and resumption mechanisms. The suspension procedure performs only the necessary minimal actions to maintain connection context, avoiding the excessive signaling of full establishment procedures while still ensuring connection reliability when data transmission is needed.
Solution Approach 2:
The connection is maintained in a continuous suspended state rather than being fully released and re-established, preserving the useful action of connection context. This continuity allows the system to maintain connection reliability through state preservation while avoiding the repeated signaling overhead of full establishment procedures, as the connection essence continues to exist in suspended form.
