Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In software-defined networking, the control device serving as a network control center cannot communicate effectively with the base station, hindering the implementation of software-defined networking in wireless communication systems.
Innovation Solution
The solution involves receiving messages from network devices, determining matching conditions based on control policies that include specific criteria such as RNTI, channel identifiers, and IP addresses, and processing these messages according to corresponding operation information, enabling the base station to process messages according to a control policy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the control plane is separated from the data plane to form a wireless network operating system, then the control plane becomes independent and centralized, but the control device cannot communicate with the base station
Solution Approach 1:
The patent introduces a flow table as an intermediary component between the control device and base station. The flow table stores flow entries that act as mediation rules, enabling the control device to communicate with the base station through predefined matching conditions and operations, thus resolving the communication barrier while maintaining control plane independence
Solution Approach 2:
The patent pre-configures flow entries in the flow table with matching conditions and operations before actual communication occurs. This preliminary setup allows the base station to automatically process messages according to pre-defined rules, enabling communication without requiring real-time control device intervention, thus solving the communication problem while preserving architectural independence
