Transaction-Sensitive Access Network Discovery and Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional access network discovery and selection functions (ANDSF) are unable to consider value-added benefits and user preferences when selecting non-cellular access networks, leading to inefficient network selection and longer processing times.
Innovation Solution
The introduction of transaction-sensitive ANDSF technology, which receives mobile device information and vendor access network resource information to determine appropriate access network resource selection based on current, historical, and predicted device states, as well as event information, allowing for improved detection and selection of access networks that provide value-added features and user preferences.

Engineering Contradiction Analysis
1Productivity
If conventional ANDSF technology is used to provide network selection rules and access network lists to UEs, then basic access network discovery and selection functionality is achieved, but the system cannot consider value-added benefits and user preferences leading to inefficient network selection and longer processing times
Solution Approach 1:
The system pre-processes and stores access network information including vendor-specific value-added benefits and user preferences in a database before selection is needed. When a UE requests network selection, the system quickly retrieves pre-analyzed recommendations rather than performing complex analysis in real-time, thus reducing processing time while maintaining selection efficiency
Solution Approach 2:
The system incorporates user feedback and historical usage patterns to continuously refine network selection recommendations. By analyzing past user choices and network performance data, the system learns user preferences and vendor benefit patterns, improving future selection efficiency and reducing processing time for subsequent selections
2Adaptability or versatility
If conventional ANDSF functionality is implemented with basic network selection rules, then the system structure remains simple, but the system lacks the capability to detect and select access networks based on vendor-specific benefits and user preferences
Solution Approach 1:
The system introduces an intermediary access network information database that stores vendor-specific value-added benefits and user preferences. This intermediary layer sits between the conventional ANDSF functionality and the UE, allowing enhanced selection capabilities without fundamentally redesigning the core ANDSF system architecture, thus managing complexity while improving adaptability
Solution Approach 2:
The system segments access network information into distinct components: basic network parameters, vendor-specific value-added benefits, user preferences, and selection recommendations. This segmentation allows each component to be processed and managed independently, enabling sophisticated selection capabilities while maintaining manageable system complexity through modular information handling

AI summary
Transaction sensitive access network discovery and selection function (TSANDSF) features are disclosed. TSANDSF features can include access network resource (ANR) selection based on vendor ANR information and UE information. TSANDSF features can further include facilitating access, via a UE, to vendor value added products or service, vendor selected information, or vendor advertisements as a result of establishing a communication link with a vendor ANR. In contrast to conventional ANDSF, TSANDSF can facilitate improved ANR ranking and selection based on rules that correlate UE information with determined vendor ANR features.
