Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If WLAN information is shared between cellular base stations and wireless LAN termination devices, then management efficiency and resource allocation are improved, but information loss and sharing inaccuracies occur
Solution Approach 1:
The patent implements a feedback mechanism where the wireless LAN termination device sends WLAN information (including AP identifiers, frequencies, and channel numbers) to the cellular base station, and the base station sends back control information. This bidirectional feedback loop ensures accurate information sharing and allows for real-time updates, resolving the issue of information loss while maintaining management efficiency.
Solution Approach 2:
The patent establishes the Xw interface between the cellular base station and wireless LAN termination device in advance, pre-configuring the information sharing framework. This preliminary setup ensures that WLAN information is accurately transmitted and shared from the beginning, preventing information loss before it occurs while enabling efficient management operations.
2Loss of information
If an interface is formed between cellular base station and wireless LAN termination node, then information sharing is improved, but device complexity increases
Solution Approach 1:
The patent designs the Xw interface to serve multiple functions: it transmits WLAN information (AP identifiers, frequencies, channel numbers), carries control information from the base station, and enables bidirectional communication. By making this single interface multi-functional, the patent avoids the need for multiple separate interfaces, thereby reducing overall device complexity while maintaining accurate information sharing.
3Productivity
If wireless LAN access points are managed through cellular base station, then resource allocation is optimized, but management precision deteriorates
Solution Approach 1:
The patent introduces the wireless LAN termination device as an intermediary between the cellular base station and the WLAN access points. This intermediary device receives detailed WLAN information directly from the access points, processes it, and shares it with the base station. This mediation ensures that the base station receives accurate and precise WLAN management information while still allowing for optimized resource allocation through the coordinated control mechanism.
