Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LTE-WLAN aggregation and interworking enhancements are implemented without standardized procedures, then network integration capability is improved, but operational complexity and management difficulty increase
Solution Approach 1:
The patent segments the LTE-WLAN integration process into distinct standardized procedures: WT addition procedure, WT modification procedure, and WT release procedure. Each procedure handles specific aspects of WLAN termination management, breaking down the complex integration task into manageable, standardized steps that reduce operational complexity while maintaining integration capability.
Solution Approach 2:
The patent introduces specific parameters and message types (e.g., WT Reconfiguration Complete message, addition modification release indicators) that standardize the control and management of WLAN termination. These parameter changes enable automated, policy-driven resource allocation and simplify the management of aggregated networks by providing structured control mechanisms.
2Ease of manufacture
If manual resource management methods are used in LTE-WLAN integration, then implementation simplicity is maintained, but network efficiency and automation level decrease
Solution Approach 1:
The patent enables the network to self-manage WLAN termination resources through automated procedures. The eNodeB automatically performs WT addition, modification, and release based on network conditions and policies, without requiring manual intervention. This self-service approach maintains implementation simplicity while significantly improving network efficiency through automated resource allocation and management.
Solution Approach 2:
The patent implements feedback mechanisms where the eNodeB receives acknowledgments (e.g., WT Addition Request Acknowledge message) and sends reconfiguration complete messages to confirm resource allocation. This structured feedback loop ensures reliable automated resource management, improving network efficiency while maintaining simplicity through standardized confirmation protocols.
3Productivity
If unified control procedures are implemented for WLAN termination management, then network management efficiency is improved, but system complexity increases
Solution Approach 1:
The patent creates universal procedures for WLAN termination management that can be applied across different scenarios (addition, modification, release). These standardized procedures provide a unified control framework that improves network management efficiency by enabling consistent, policy-driven resource allocation across the entire LTE-WLAN aggregated network, while the modular nature of the procedures keeps system complexity manageable.

AI summary
A method and apparatus for performing a wireless local area network (WLAN) termination (WT) addition/modification procedure in a wireless communication system is provided. For the WT addition procedure, an eNodeB (eNB) transmits a WT Addition Request message to a WT via a Xw interface, and receives a WT Addition Request Acknowledge message from the WT via the Xw interface. For eNB initiated WT modification procedure, the eNB transmits a WT Modification Request message to a WT via a Xw interface, and receives a WT Modification Request Acknowledge message from the WT via the Xw interface. For the WT initiated WT modification procedure, the eNB receives a WT Modification Required message from a WT via a Xw interface, and transmits a WT Modification Confirm message to the WT via the Xw interface. The WT is a logical node that terminates the Xw interface.
