Wireless Terminal Interworking Control via Network Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, existing technologies face challenges in efficiently controlling interworking between heterogeneous networks due to the UE's autonomous decision-making, which hinders network efficiency and leads to increased transmission delays and re-transmissions when interworking with different access points.
Innovation Solution
A method where the UE performs interworking procedures with a second network and reports the results to the first network, allowing the first network to instruct and configure the UE for efficient interworking, including authentication, association, and authorization procedures, and measurement configurations for access points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the UE autonomously determines whether to perform interworking with a second network, then the UE can independently manage interworking procedures, but the network cannot control transmission efficiency and monitor interworking results
Solution Approach 1:
The UE reports the result of interworking procedures to the first network, creating a feedback mechanism that allows the network to monitor and control interworking operations while maintaining UE autonomy in decision-making
Solution Approach 2:
The first network provides measurement configuration for access points in the second network before the UE performs interworking, allowing the network to pre-establish control parameters and criteria for successful interworking
2Adaptability or versatility
If the UE performs interworking with multiple access points in the second network, then interworking flexibility increases, but transmission delays increase and aggregation of partial streams becomes difficult
Solution Approach 1:
The first network provides measurement configuration including criteria for successful interworking before the UE performs interworking procedures, allowing the UE to pre-evaluate access points and select only those meeting the criteria, thus avoiding unnecessary transmission delays
Solution Approach 2:
The measurement configuration includes specific parameters and thresholds that the UE uses to evaluate access points, changing the decision-making parameters based on network conditions and requirements to optimize transmission timing
3Speed
If the UE autonomously selects access points for interworking, then the interworking procedure can be initiated quickly, but the first network cannot be aware of the situation and control the process
Solution Approach 1:
The UE reports the result of interworking procedures including which access point was selected and whether the procedure succeeded, providing the first network with complete awareness of the interworking situation while maintaining fast UE-initiated selection
