Link Setup Level Coordination for Wireless Terminal Offloading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face inefficiencies in link setup and data offloading due to infrequent network updates, network congestion, and device link failures, which affect service quality and increase delays in discovering and authenticating with WLAN networks.
Innovation Solution
The method involves determining and communicating a minimum and maximum link setup level to a terminal, allowing it to perform specific operations before reporting network availability, with the evolved Node B (eNB) coordinating wireless local area network (WLAN) operations and setting expected link setup levels based on access technologies, traffic types, and network conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal performs complete link setup operations (discovery, authentication, association) before reporting network availability, then the reliability of network connection is improved, but the time delay and power consumption increase
Solution Approach 1:
The terminal performs preliminary link setup operations (discovery, authentication, association) with the WLAN network before the actual data offloading is needed. By completing these operations in advance and reporting network availability to the base station, the terminal ensures reliable network connection when needed while avoiding time delays during actual data transmission.
Solution Approach 2:
The link setup process is segmented into distinct phases: discovery phase, authentication phase, association phase, and data transmission phase. The terminal can report network availability after completing authentication and association, while the actual data transmission occurs in a separate phase, allowing the system to balance between connection reliability and transmission speed.
2Reliability
If the terminal performs complete authentication and association operations, then the security and stability of network connection are improved, but the power consumption and processing overhead increase
Solution Approach 1:
Authentication and association operations are performed in advance before data offloading is required. The terminal completes these power-intensive operations when the network is available, reports availability to the base station, and can quickly resume data transmission without repeating the authentication process, thereby reducing overall power consumption while maintaining connection stability.
3Reliability
If the network discovers and authenticates WLAN networks frequently to ensure availability, then the service quality is improved, but the processing overhead and network congestion increase
Solution Approach 1:
The terminal autonomously performs WLAN network discovery, authentication, and association operations without requiring continuous network coordination or control. The terminal independently manages its link setup process, reports availability to the base station, and can resume data transmission quickly, reducing processing overhead on the network side while ensuring service availability.

AI summary
Various communication systems may benefit from coordination in interworking. For example, certain wireless communication systems may benefit from link setup level coordination, such as coordination between a first radio access technology base station and a terminal that is setting up a link to a second radio access technology. A method may include, for example, determining an allowed link setup level for a terminal. The method may also include communicating the allowed link setup level to the terminal.
