3GPP Network Service Transfer Optimization via UE Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communications, the existing methods for service transfer between 3GPP and WLAN networks often result in inefficient resource utilization due to inappropriate policy selection by the 3GPP network side, leading to suboptimal service quality and resource waste, as user equipment (UE) may select WLAN access points based on policies other than those sent by the 3GPP network, and the network lacks feedback to optimize its assistance.
Innovation Solution
A method where the UE acquires and reports service transfer results to the 3GPP network, using information types A, B, and C to determine and select a target WLAN access point, allowing the network to optimize its parameters and improve resource allocation based on actual service transfer outcomes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the 3GPP network side directly assists or controls the UE to select the WLAN access point, then service transfer efficiency of the terminal is improved, but system resources of the 3GPP network are wasted due to inappropriate policy selection
Solution Approach 1:
The patent implements a feedback mechanism where the UE reports service transfer results (success or failure) back to the 3GPP network side. The network side uses this feedback to optimize assistance information for future service transfer operations. This closed-loop feedback system enables the network to learn from actual outcomes and improve policy appropriateness, thereby reducing resource waste while maintaining high service transfer efficiency.
2Adaptability or versatility
If the UE selects a WLAN access point by itself, then selection flexibility is improved, but WLAN access points become overloaded in crowded places resulting in deteriorated service quality
Solution Approach 1:
The patent introduces the 3GPP network side as an intermediary that provides assistance information to guide UE's WLAN access point selection. The network side obtains information about multiple WLAN access points and uses this information to generate optimized assistance information that the UE then uses for selection. This intermediary role maintains UE selection flexibility while ensuring that selected access points are appropriate and not overloaded, thus preserving service quality.
3Extent of automation
If the 3GPP network side sends policy information to assist UE selection, then service transfer control is improved, but the UE may not follow the policy resulting in resource waste
Solution Approach 1:
The patent implements feedback where the UE reports whether service transfer succeeded or failed to the 3GPP network side. Based on this feedback, the network side optimizes its assistance information and policy recommendations. This feedback loop ensures that the network can adapt its automated control policies to actual outcomes, improving the likelihood that UEs will successfully follow the policies while reducing resource waste from inappropriate policy enforcement.
