Visited Network Data Saving Profiles for Selective UE Traffic Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment (UE) experiences varying performance and charges when connecting to visited telecommunication networks, leading to poor user experience and additional costs due to unoptimized data transmission behaviors.
Innovation Solution
A data saving profile is activated in response to triggering events, applying rules that limit some data transmissions without stopping all data transmissions, including features like stopping background data, limiting SMS retries, and restricting certain network uses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data transmission rules are configured for home network behavior, then data transmission is optimized for home network performance and charges, but data transmission performance deteriorates when connected to visited networks
Solution Approach 1:
The patent implements dynamic data transmission rules that automatically adjust based on network detection. The system transitions from static home-network-optimized rules to dynamic rules that adapt when a visited network is detected, modifying parameters such as background data transmission, SMS retry behavior, and timeout settings to match visited network conditions.
Solution Approach 2:
The system changes transmission parameters when transitioning from home to visited networks. Specific parameters including background data transmission rates, SMS retry attempts, and timeout values are modified to align with visited network performance characteristics and charging models, resolving the contradiction between home network optimization and visited network performance.
2Loss of energy
If all data transmissions are stopped to avoid additional charges, then cost is reduced, but user connectivity and data transmission capability are lost
Solution Approach 1:
The patent segments data transmissions into different categories with different rules. Essential user-initiated transmissions are permitted while background and automated transmissions are restricted or stopped. This segmentation allows the system to reduce costs by eliminating unnecessary transmissions while preserving user connectivity and essential data exchange.
Solution Approach 2:
Instead of stopping all data transmissions, the system applies partial action by selectively limiting only certain types of transmissions (background data, automated updates) while allowing essential user-initiated communications. This partial restriction achieves cost reduction without completely sacrificing user connectivity.
3Loss of energy
If data transmissions are limited to reduce costs, then additional charges are reduced, but user experience deteriorates due to slow loading and timeouts
Solution Approach 1:
The patent applies different quality levels of data transmission to different types of data. High-priority user-initiated transmissions receive full bandwidth and no artificial limitations, while background and low-priority transmissions are restricted. This local quality differentiation ensures excellent user experience for essential operations while reducing costs through selective limitation of non-essential transmissions.
Solution Approach 2:
The system implements feedback mechanisms to monitor transmission performance and user behavior. Based on this feedback, the system dynamically adjusts which transmissions are limited and which are permitted, ensuring that cost-saving measures do not degrade essential user experience while still achieving overall cost reduction.
Data Source
AI summary
Described herein is a user equipment (UE) configured to determine an occurrence of a triggering event associated with a data saving profile and, in response, activate the data saving profile. The data saving profile includes rules for at least two of stopping background data, limiting short message service (SMS) retries, early timeouts, stopping incoming calls or redirecting incoming calls to voicemail, blocking video streaming, limiting connection attempts, restricting use of the UE as a personal hotspot, or restricting use of certain access point names (APNs) or data network names (DNNs). The UE then applies the rules of the data saving profile to at least one of incoming data or outgoing data. The applying of the rules limits some data transmissions without stopping all data transmissions.
